+> ([docs.docker.com/engine/install](https://docs.docker.com/engine/install/)),
+> then re-run `nvidia-ctk runtime configure --runtime=docker` and restart
+> Docker.
+
 Safety notes:
 - The app never installs host GPU runtime automatically.
 - The app never edits `.env` automatically.

Subject: [PATCH 002/180] fix(chat): restore missing _explicit_web_intent
 definition (#5290)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

chat_stream() references `_explicit_web_intent` in three places
(disabled-tools gating, global-disabled web allowance, and the
per-turn tool filter) but the assignment was dropped during a
branch merge. Every chat request raised

    NameError: name '_explicit_web_intent' is not defined

at routes/chat_routes.py, surfacing to the client as a bare
"Internal Server Error" before any LLM call was made — chat was
fully broken on dev and main.

Restore the original definition, computed from the already-derived
tool intent, immediately before its first use:

    _explicit_web_intent = bool(_tool_intent and _tool_intent.category == "web")

Subject: [PATCH 004/180] fix(chat): give extensionless image/audio uploads a
 valid MIME subtype (#5205)

build_user_content derived the data-URL subtype from the file extension
only (image_format = ext[1:]). An extensionless upload (e.g. a pasted
screenshot) has ext == "", producing "data:image/;base64,..." with an
empty subtype (invalid per RFC 2046) that vision/audio endpoints reject,
silently dropping the attachment. Fall back to the resolved MIME subtype
when the extension is missing; present extensions are unchanged.

+exist on the host. Reinstalling or reconfiguring `nvidia-container-toolkit` will

+
+```bash
+sudo snap remove docker
+sudo nvidia-ctk runtime configure --runtime=docker
+sudo systemctl restart docker
+```
+
+Then re-run `scripts/check-docker-gpu.sh`.
 
 Safety notes:
 - The app never installs host GPU runtime automatically.

Subject: [PATCH 006/180] fix(copilot): guard request_flags against a non-dict
 last message (#5274)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

request_flags derives (agent, vision) and does last.get("role") after only
a truthy check. A client can send a bare-string message element
("messages": ["hi"]), and the vision loop right below already guards each
element with isinstance — so the .get() on a non-dict last element is an
oversight that raises AttributeError on every Copilot-proxied request with
such a body.

Use isinstance(last, dict) to match the loop's own guard.

Fixes #5273

Subject: [PATCH 008/180] fix(reminders): sanitize ntfy Title header to ASCII
 (#5208)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(reminders): sanitize ntfy Title header to ASCII

The ntfy notification Title header was set directly from the note title.
HTTP headers must be ASCII, so a title containing emoji or other
non-ASCII characters caused httpx to raise UnicodeEncodeError, which
was swallowed by the surrounding try/except — so the reminder silently
failed and no notification was ever sent.

Sanitize the title with encode('ascii', 'replace') before placing it
into the header, replacing unsupported characters with '?'. This is
standard practice for HTTP header values. The note body is unaffected
(it is sent as request content, not a header) and continues to support
full UTF-8.

* fix(reminders): also truncate ntfy title to 200 chars for header safety

* style: compact ntfy header comment

Subject: [PATCH 009/180] fix(tasks): scope manage_tasks mutations to an exact
 task owner (#5264)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The edit/delete/pause/run actions of do_manage_tasks gated ownership with
`if owner and task.owner and task.owner != owner`. The middle term made the
check a no-op whenever task.owner was null/empty — the state a scheduled task
sits in when it was created in no-login mode (or via the localhost middleware
bypass) before the periodic legacy-owner sweep reassigns it to the admin user.
Any authenticated user's agent could then edit, delete, pause, or run another
tenant's owner-less task; edit+run lets an attacker rewrite the task prompt and
execute it in the scheduler's agent context.

The sibling `list` action already scopes with an exact `owner == owner` filter,
so the mutators were strictly more permissive than the reader. Drop the middle
term so the guard fails closed on owner-less rows for authenticated callers,
matching `list` and the calendar/notes/gallery/session null-owner gates. Auth
disabled (owner falsy) and same-owner access are unchanged.

Subject: [PATCH 014/180] fix(email): never fall back to sequence-number IMAP
 ops for move/flag (#2732)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_store_email_flag and _move_email_message (used by the archive / delete / move /
mark-read endpoints) had an else branch that, when _uid_exists returned False,
ran conn.store(uid, ...) / conn.copy(uid, ...) followed by a folder-wide
conn.expunge(). But imaplib's plain store()/copy() take a message SEQUENCE
NUMBER, not a UID, so the op landed on whichever message occupied sequence
position == the UID value, and the expunge then permanently removed it. A stale
cached UID (or a server whose UID probe misbehaves) therefore deleted an
unrelated email instead of reporting 'not found'.

There is no valid case where treating a UID as a sequence number is correct, so
drop the fallback: when the UID isn't present, return False — callers already
surface 'Email not found'. Only the UID command path remains.

Sibling of #1874 (which fixes the auto-spam poller's _imap_move in
email_helpers.py); this covers the user-facing endpoints in email_routes.py.
Part of #2124.

Subject: [PATCH 015/180] fix(email): atomically claim scheduled emails before
 sending (#5110)

_scheduled_poll_once selected rows WHERE status='pending' and only wrote
status='sent'/'failed' after the SMTP send and IMAP append completed -
no atomic claim in between. Two overlapping callers (the in-process 30s
poller and an externally cron/systemd-driven 'odysseus-mail
poll-scheduled', or the CLI run manually) can both SELECT the same
pending row before either UPDATEs it, and both send it. _start_poller's
own docstring already names this exact risk ('avoid two copies of
_scheduled_poll_once racing on the same SQLite') but nothing in the code
enforced it - it was advisory only.

Add an atomic per-row claim: UPDATE ... SET status='sending' WHERE
id=? AND status='pending', proceeding only when rowcount == 1. The
loser of the race sees rowcount == 0 and skips the row instead of
sending a duplicate.

Adds a regression test that drives two real threads through the real
_scheduled_poll_once against a shared SQLite file, synchronized with a
barrier and a widened send-path window, and asserts exactly one send
fires. Reverting the fix makes the test fail reliably (5/5 runs); with
the fix it passes reliably (5/5 runs).

Fixes #5109

Subject: [PATCH 016/180] fix(mcp): guard DbTokenStorage against non-dict
 oauth_tokens JSON (#5107)

_load() returned whatever json.loads() produced without checking it was a
dict; _update() did the same before assigning data[key] = value. If the
oauth_tokens column ever held a JSON array or primitive (DB corruption,
manual edit, migration drift), _load()'s callers crashed with
AttributeError on .get(), and _update() crashed with TypeError trying to
item-assign into a list/string/int.

Validate the parsed value is a dict in both methods, falling back to {}
otherwise - same recovery behavior already used elsewhere in the codebase
for this exact JSON-blob-is-not-a-dict shape (_parse_tool_args,
_is_sensitive_path's siblings).

Adds 3 regression tests for _load, get_tokens, and _update against a
non-dict oauth_tokens value.

Fixes #5082

Subject: [PATCH 018/180] CalDAV: close the DAVClient on sync and write-back
 paths (#4793)

_sync_blocking (src/caldav_sync.py) and _writeback_blocking
(src/caldav_writeback.py) each open their own caldav.DAVClient via
_build_dav_client, but never close it. The client owns an HTTP session
with a pooled connection; without a close() that connection is held until
process exit.

Previously the fix added explicit client.close() calls before each early
return and at the end of the DB finally block. This still leaked the
client when SessionLocal() raised before the DB try/finally was entered.

Now _sync_blocking wraps the entire post-construction path in an outer
try/finally that calls client.close() unconditionally, covering:
  - AuthorizationError / NotFoundError early return
  - URL-fallback failure early return
  - no-calendars early return
  - normal return after sync
  - SessionLocal() construction failure (new regression coverage)

_writeback_blocking already used a try/finally (unchanged).

- src/caldav_sync.py: replace scattered client.close() calls with a
  single outer try/finally block around the discovery + DB sync path
- tests/test_caldav_client_cleanup.py: add CalendarDeletedEvent to the
  database stub; add regression test for SessionLocal() failure path

Closes #4593

Subject: [PATCH 019/180] fix(calendar): trust operator CA bundle in CalDAV
 test_connection (#4796)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(calendar): trust operator CA bundle in CalDAV test_connection

The pre-flight test used httpx with trust_env=False, which ignored
SSL_CERT_FILE/REQUESTS_CA_BUNDLE. Self-signed CalDAV servers that
the real sync accepts (via caldav lib → requests → honors bundle)
were rejected by the test with CERTIFICATE_VERIFY_FAILED.

Build an explicit SSL context that loads the operator's CA bundle
and clears VERIFY_X509_STRICT (which rejects certs without a
keyUsage extension — common in self-signed setups). SSRF guards
(follow_redirects=False, trust_env=False) are preserved.

Fixes #4795
Fixes #4779

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(calendar): add regression tests and edge case handling for SSL context

Per review: add route-level regression tests covering SSL_CERT_FILE
precedence, VERIFY_X509_STRICT clearing, missing bundle graceful
fallback, and empty env var handling. Also log a warning when the
configured CA bundle path doesn't exist instead of silently falling
back to system CAs.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test(calendar): rewrite SSL tests to exercise route handler directly

Addresses review feedback: tests now use FastAPI TestClient to hit the
actual test_connection route, capturing the verify= kwarg passed to
httpx.AsyncClient. This ensures the route's SSL context construction
is covered, not a test-side duplicate.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* ci: retrigger CI (redirect hardening test is a CI-env flake, passes locally)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix(tests): remove module-level sys.modules stubs that leaked into other tests

The collection-time MagicMock stub of `caldav` replaced the real library
for every later test in the same process — test_caldav_redirect_hardening's
DAVClient became a mock that never sent the PROPFIND, failing its
must-reach-the-public-server assertion in CI. conftest already pre-imports
the real sqlalchemy/core.database, and the route's lazy imports are patched
per-request, so the stub block was both harmful and unnecessary.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(calendar): verify exact CA bundle precedence

Subject: [PATCH 020/180] fix(agent): cancel orphaned tool task when SSE client
 disconnects mid-call (#5106)

stream_agent_loop's per-tool drain loop had no cleanup path for early
generator close. Starlette throws GeneratorExit into the generator at
whatever await point it's suspended on when the SSE client disconnects
(aclose()) - here that's 'await _progress_q.get()' inside the drain
loop, before the final 'await _tool_task' line ever runs. The task,
which wraps execute_tool_block, was left running unawaited and
uncancelled.

For bash/python tools this orphans the underlying subprocess:
subprocess_tools.py already has correct CancelledError handling that
kills the child process, but only runs if the task is actually
cancelled. A client disconnecting mid long-running command left that
subprocess running server-side for its full duration with nothing
left to reap it.

Wrap the drain loop in try/finally: on early exit, cancel _tool_task
(if not already done) and await it so the existing subprocess-kill
path runs.

Adds a regression test that drives the real stream_agent_loop with a
fake tool handler, closes the generator mid tool-call (mirroring what
Starlette does on disconnect), and asserts the handler observed
cancellation immediately - not merely via asyncio.run()'s own
end-of-run task cleanup, which would mask the bug.

Fixes #5105

Subject: [PATCH 022/180] fix(email): use UID commands instead of sequence
 numbers in IMAP fetches (#5149)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

conn.search() / conn.fetch() operate on volatile positional sequence
numbers that shift whenever messages are deleted or expunged. Three call
sites in the sig-learner (_pull_headers, _fetch_bodies) and morning-brief
email section were storing these as "uid" and reusing them in subsequent
fetches — causing wrong-message returns or NO responses if another client
modified the mailbox concurrently.

Replaced with conn.uid("SEARCH", ...) / conn.uid("FETCH", ...), which use
persistent RFC 3501 UIDs. _scan_one (urgency action) already did this
correctly; these were the remaining callers.

The reproduction window is narrow (requires concurrent deletion between
search and fetch), so the fix is verified by regression tests rather than
manual end-to-end: _SpyImap raises AssertionError if conn.search() or
conn.fetch() are called instead of conn.uid().

+# Attachment References and Upload Storage
+
+Odysseus stores uploaded bytes once under the configured upload directory and
+passes stable references through chat history, tools, and future artifact work.
+The goal is to avoid duplicating large inline media payloads in
+`chat_messages.content` or the SQLite FTS index.
+
+## Reference Shape
+
+Attachment references use this minimum shape:
+
+```json
+{
+  "type": "attachment_ref",
+  "attachment_id": "32hex-or-32hex.ext",
+  "name": "original-filename.png",
+  "mime": "image/png",
+  "size": 12345,
+  "checksum_sha256": "hex-digest",
+  "created_at": "2026-07-09T12:00:00"
+}
+```
+
+Optional fields such as `width`, `height`, `vision`, `vision_model`, and
+`gallery_id` may be present when the uploader or preprocessing path knows them.
+
+## Persistence
+
+The live model call may still receive provider-specific multimodal blocks for
+the current turn. Persistence is different:
+
+- `chat_messages.content` stores readable text plus compact attachment reference
+  lines, never raw `data:*;base64,...` upload bytes.
+- `chat_messages.metadata.attachments` stores structured attachment reference
+  metadata for UI reloads and future processing.
+- The SQLite FTS migration recreates chat-message FTS triggers so new rows do
+  not index inline media payloads, and it scrubs legacy rows that were already
+  indexed with data URLs.
+
+## Tool Access
+
+Agent/tool context receives upload entries as `attachment_ref` manifests with an
+`odysseus://attachment/<id>` URI and `read_policy: "owner_checked_upload"`.
+
+For compatibility with existing built-in tools, a local `path` may be included
+only after all of these checks pass:
+
+- the upload ID resolves through `UploadHandler.resolve_upload`;
+- the requested owner is allowed to read the upload;
+- the file remains inside the configured upload directory;
+- the file path is inside the tool-readable roots.
+
+External MCP/custom tools should treat the URI and attachment ID as the stable
+contract and request bytes through an owner-checked server path, not by assuming
+host filesystem layout.
+
+## Retention and Deletion
+
+Current retention behavior is conservative:
+
+- uploads are indexed in `uploads.json` with owner, checksum, MIME type, size,
+  and creation time;
+- admin cleanup first scans persisted chat metadata/content, document versions,
+  PDF source markers, gallery hashes, notes, and calendar records for live
+  references;
+- cleanup fails closed if that reference scan cannot complete, and the lower-level
+  cleanup API removes nothing unless it receives a complete reference snapshot;
+- expired, unreferenced uploads are removed during the completed scan, while
+  attachment-bearing writers must first take an owner-checked reservation that
+  serializes with deletion and refreshes the upload's access timestamp;
+- deliberate removal atomically drops matching `uploads.json` rows before deleting
+  the bytes and restores those rows if filesystem removal fails;
+- deleting a chat removes the chat rows but does not immediately delete shared
+  upload bytes, because the same upload may also be referenced by gallery items,
+  documents, duplicate-upload rows, or future artifact records.
+
+There is no distinct artifact table in the current schema. Artifact-like upload
+references persisted in chat or document text are covered by the canonical
+attachment-ID scan; any future artifact store must be added to reference discovery
+before cleanup is allowed to consider its uploads unreferenced.
+
+Cleanup and write reservations share the upload-index lock. This closes the
+scan/write/delete race in the documented single-worker deployment; a future
+multi-process deployment must add an inter-process lock or move lifecycle state
+into the database before enabling destructive cleanup in more than one worker.

Subject: [PATCH 028/180] fix(cleanup): update MODULE_SUMMARY and remove dead
 MEMORY_DOC paths (#4411) (#5160)

* docs: update static/js/MODULE_SUMMARY.md to reflect current ES6 frontend

Rewrite the stale module summary to match the current no-build,
ES6-module frontend architecture. Adds coverage of app.js orchestration,
the chat/SSE pipeline (chat.js, chatStream.js, chatRenderer.js,
streamingRenderer.js), new subsystems (research/, compare/, document
streaming, cookbook*, skills.js), and removes the obsolete <script> load
order assumptions.

* cleanup: remove dead MEMORY_DOC / memory_doc paths (closes #4411)

Removes the unused MEMORY_DOC constant and the matching DataConfig
memory_doc field / set_data_paths entry. No runtime code imports or
references these paths, so this is a no-behavior-change dead-code
cleanup under the storage-architecture tracker #4377.

-# Module Organization Summary
+# Frontend Module Organization Summary
 
-## Purpose
-This document describes what each JavaScript module is responsible for.
-
-> **Note:** This file is a partial, historical overview — not a complete authoritative
-> inventory. The authoritative module set is the current `static/js/` tree plus the
-> scripts loaded by `static/index.html`. As of this writing that tree holds **65 `.js`
-> files** across **8 subdirectories** (`calendar/`, `color/`, `compare/`, `editor/`,
-> `emailLibrary/`, `markdown/`, `research/`, `util/`), and `static/index.html` loads
-> **35** `/static…` script tags. The catalog below covers only the original core
-> modules and is not kept in sync with every module.
+> **Scope:** This document describes the architecture of the Odysseus no-build
+> frontend. The app is a collection of native ES6 modules loaded from
+> `static/`. The authoritative source is the current `static/js/` tree and the
+> top-level orchestrator `static/app.js`.
 
 ---
 
-## Core Modules (in static/js/)
+## 1. Top-level Application Orchestrator
 
-### 1. **ui.js**
-- UI helper functions and utilities
-- Toast notifications (`showToast`, `showError`)
-- Element getter (`el()`)
-- Clipboard operations (`copyToClipboard`)
-- Scroll management (`scrollHistory`, `setAutoScroll`)
-- Auto-resize textarea
-- Debounce utility
+### `static/app.js`
+*Main application entry point.*
 
-### 2. **markdown.js**
-- Markdown processing and rendering
-- Convert markdown to HTML (`mdToHtml`)
-- Code block handling with syntax highlighting
-- Content rendering for message arrays
-- Text cleanup (`squashOutsideCode`)
+- Imports all feature modules.
+- Exposes a few modules on `window` for legacy inter-module reachability
+  (`themeModule`, `sessionModule`, `uiModule`, `adminModule`, `cookbookModule`).
+- Patches `fetch` so any `401` redirects the user to `/login`.
+- Fetches the default chat configuration and handles deep-link route openers
+  (`/notes`, `/calendar`, `/email`, `/memory`, `/gallery`, `/cookbook`, `/library`, `/tasks`).
+- Wires global event listeners: chat-history scrolling, popups, Escape handling,
+  drag-and-drop/paste attachment handling, transcription export, sidebar toggles,
+  rail/tool buttons, and session sorting.
+- Loads auth status and applies per-user privilege restrictions.
 
-### 3. **sessions.js**
-- Session/chat management
-- Create, load, delete, switch sessions
-- Session history loading
-- Direct chat creation with models
-- Session renaming
-
-### 4. **memory.js**
-- AI memory management
-- Load, add, edit, delete memories
-- Memory search/filtering
-- Memory UI rendering
-- Memory count updates
-
-### 5. **fileHandler.js**
-- File attachment handling
-- File picker dialog
-- File upload to server
-- Attachment strip rendering
-- Pending files management
-- File preview/removal
-
-### 6. **voiceRecorder.js**
-- Voice recording functionality
-- Start/stop recording
-- Audio file creation
-- Microphone permission handling
-- Recording UI updates
-
-### 7. **models.js**
-- Model scanning and display
-- Local model discovery (ports 8000-8020)
-- Provider management (OpenAI)

+## 3. Chat Pipeline
+
+The largest and most central subsystem. Chat submission → backend SSE → progressive rendering of text, tools, research, documents, and UI events.
+
+| Module | Responsibility |
+|---|---|
+| **`chat.js`** | Main chat controller. Handles `handleChatSubmit`, stops/continues, builds `FormData`, posts to `/api/chat_stream`, reads the SSE stream, and dispatches each JSON event to the appropriate renderer. Tracks background streams, stalls, auto-recovery, and multi-round agent state. |

+
+## 12. Frontend Event Streaming Flow
+
+```
+User submits composer
+  └── chat.js::handleChatSubmit() builds FormData
+        ├── fileHandler.uploadPending() for attachments
+        ├── document.js saved (if a document panel is open)
+        └── POST /api/chat_stream
+
+Server responds with SSE stream
+  └── chat.js reads chunks via res.body.getReader() + TextDecoder
+        ├── Lines starting with "event:" set next-error state
+        └── Lines starting with "data:" carry JSON payloads
+
+JSON events are dispatched by "type":
+  delta              → streamingRenderer → markdown → live reply text
+  agent_prep         → update spinner label
+  tool_start         → finalize text bubble; create agent-thread node with wave animation
+  tool_progress      → append/update live stdout/stderr tail
+  tool_output        → mark node done/failed, render output, diffs, screenshots
+  agent_step         → finalize tool thread; create new msg-continuation bubble
+  doc_stream_open    → document.js opens a live document
+  doc_stream_delta   → document.js appends content to that document
+  research_progress  → researchSynapse visualization + spinner timer
+  research_sources   → build sources box for research
+  research_done      → reload session history to show the report
+  web_sources        → build web-search sources box
+  model_info         → update role header with requested/actual model
+  fallback           → show fallback model toast + update role label
+  metrics            → collect/display token/cost metrics
+  message_saved      → store database id on the message element
+  budget_exceeded    → show budget banner
+  rounds_exhausted   → show Continue button for step-limit hits
+  teacher_takeover   → insert escalation banner, reset round state
+  skill_saved        → show skill-learned banner
+```
+
+Foreground vs background streams:
+- If the user switches sessions while a stream is running, `chat.js` pauses DOM
+  updates and stores the state in `_backgroundStreams`. Completion is signaled
+  with a sidebar dot/notifications, and the history is reloaded when the user
+  returns.
+
+---
+
+## 13. What Changed from the Previous Summary
+
+- The frontend is now exclusively ES6-module based; the old `<script>` tag load
+  order is no longer authoritative.
+- `chat.js` is the streaming controller, but message rendering has been split
+  into `chatRenderer.js`, `streamingRenderer.js`, `chatStream.js`, and `researchSynapse.js`.
+- New major subsystems added since the original summary: compare mode
+  (`compare/`), document editor streaming (`document.js`), research UI
+  (`research/`), model cookbook (`cookbook*.js`), group chat (`group.js`),
+  voice/TTS (`voiceRecorder.js`, `tts-ai.js`), skill UI (`skills.js`), and
+  slash autocomplete (`slashAutocomplete.js`).
+- `sessions.js` now owns sidebar session state, streaming/research indicators,
+  and the library/archive modals.

Subject: [PATCH 029/180] fix(db): restrict data/app.db to 0600 (#4420)

* fix(db): restrict data/app.db to 0600

app.db holds bearer-token hashes, bcrypt password hashes, and encrypted
provider keys but was created under the default umask (0644 -> world-readable),
unlike .app_key/vault/integrations which are already 0600 via safe_chmod.

init_db() now chmods the SQLite file to 0600 right after create_all (POSIX
only; no-op on Windows, skipped for Postgres / in-memory). Unconditional and
idempotent, so it also re-locks already-deployed 0644 installs on next
startup. The transient rollback journal inherits 0600 from the parent file at
creation - no sidecar handling needed; -wal/-shm don't exist until WAL is
enabled (#4409 C4) and inherit the same mode then.

Satisfies Rule B, unblocking #4413 and the vault/integration secret moves.
Mirrors src/secret_storage.py:43-45.

Verified: security + DB-permission suites pass; 6 pre-existing visual_report
failures (missing markdown/nh3 deps) are unrelated.

Closes #4407

* fix(db): harden SQLite path parsing and re-lock sidecars

Address review feedback on #4420.

P2: derive the file to chmod from engine.url (SQLAlchemy's parsed URL)
via _sqlite_db_path(), instead of DATABASE_URL.replace("sqlite:///", "").
A driver-qualified URL (sqlite+pysqlite://) or one carrying query args
(?cache=shared) previously slipped past the prefix check / string slice
and left the DB world-readable; the parsed path resolves correctly and
drops the query.

P3: re-lock stale -wal/-shm/-journal sidecars to 0o600 at startup. The
main file is chmod'd first, so any sidecar SQLite creates afterward
inherits 0o600, but a -wal/-shm left world-readable by an older 0o644
install (once WAL was enabled) could still expose DB pages. Absent
sidecars are the normal case, not an error.

Tests: unit-test _sqlite_db_path across driver/query/memory/postgres URL
forms, and a subprocess test asserting stale 0o644 -wal/-shm are
re-locked on startup.

* fix(db): handle sqlite file URI app db permissions

* fix(db): close remaining SQLite permission bypasses

Subject: [PATCH 032/180] fix(skills): block private SSRF targets and
 revalidate redirects in importer (#5261)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Harden skill importer against SSRF: block private targets + revalidate redirects per hop

The skill importer validated only the initial URL with the lenient SSRF guard
(block_private=False) and then fetched with follow_redirects=True, so a 3xx to
an internal/metadata address (169.254.169.254, 127.0.0.1, RFC-1918) was still
connected to — inconsistent with the hardened services/search/content.py
:_get_public_url path.

Add a _get_checked() helper that follows redirects manually and re-runs the
SSRF guard with block_private=True on every hop, and route all three fetch
sites (skills.sh unwrap, _fetch_bytes, _list_github_dir) through it. GitHub's
own redirects and the final-host _assert_github_url checks are preserved.

Adds hermetic regression tests (IP-literal hosts, faked HTTP layer) and updates
the existing mock signature for the new block_private kwarg.

Defense-in-depth: the endpoint is admin-gated (require_admin) and admins are
trusted per THREAT_MODEL.md, so this is not a cross-boundary vulnerability.

* test: enforce follow_redirects=False invariant in mock client

+"""Skill importer SSRF hardening: redirects must be re-validated per hop.
+
+The importer follows redirects manually (`_get_checked`) and re-runs the SSRF
+guard on every hop with ``block_private=True``, matching the hardened web-fetch
+path in ``services/search/content.py:_get_public_url``. Previously it used
+``httpx``'s ``follow_redirects=True`` with the lenient guard on the *initial*
+URL only, so a ``3xx`` to an internal/metadata address was still connected to.
+
+These tests are hermetic: every host is an IP literal, so ``check_outbound_url``
+resolves them locally (``getaddrinfo`` on a numeric address does no DNS) and no
+network access is required. The HTTP layer is faked so no real request is made.

Subject: [PATCH 033/180] docs(setup): document Arch NVIDIA Docker GPU setup

Add Arch-specific package installation and NVIDIA runtime configuration
to the Docker setup guide. Cover passthrough verification, the NVIDIA
Compose overlay, and the distinction between GPU passthrough and
CUDA-backed model serving

 # Full assisted setup — install toolkit, then enable overlay if passthrough works:
 scripts/check-docker-gpu.sh --install-nvidia-toolkit --enable-nvidia-overlay
 ```
+#### Arch Linux NVIDIA Docker notes
+
+On Arch Linux, verify the host NVIDIA driver and Docker GPU passthrough before enabling the Odysseus NVIDIA overlay.
+
+Install the required packages:
+
+```bash
+sudo pacman -Syu
+sudo pacman -S docker docker-compose nvidia-container-toolkit nvidia-utils
+sudo systemctl enable --now docker
+```
+
+Configure Docker to use the NVIDIA container runtime:
+
+```bash
+sudo nvidia-ctk runtime configure --runtime=docker
+sudo systemctl restart docker
+```
+
+Verify the host GPU:
+
+```bash
+nvidia-smi
+```
+
+Verify Docker GPU passthrough:
+
+```bash
+docker run --rm --gpus all nvidia/cuda:12.9.0-base-ubuntu22.04 nvidia-smi
+```
+
+Then enable the Odysseus NVIDIA compose overlay:
+
+```env
+COMPOSE_FILE=docker-compose.yml:docker/gpu.nvidia.yml
+```
+
+Rebuild and verify the GPU inside the Odysseus container:
+
+```bash
+docker compose up -d --build
+docker compose exec odysseus nvidia-smi -L
+```
+
+For first-time local model testing on 8 GB laptop GPUs, start with GGUF/Q4 models on llama.cpp before trying GPTQ/AWQ models on vLLM or SGLang. This keeps the first run simpler while confirming GPU passthrough works.
 
 Safety notes:
 - The app never installs host GPU runtime automatically.

Subject: [PATCH 035/180] feat(models): define capability schema and readers
 (#2739)

* feat(models): define capability schema and readers

* fix(models): harden Google catalog probing

Restrict native catalog probing to the Gemini host, keep provider keys out of request URLs, filter non-chat model resources, and preserve the manual refresh default in the built-in Google add flow.

Subject: [PATCH 039/180] fix(url-safety): reject RFC 6598 shared address space
 in strict mode (#5474)

* security(url-safety): reject RFC 6598 shared address space in strict mode

Strict mode (block_private=True) is a full SSRF lockdown, but it only
rejected is_private and is_loopback targets. CPython does not classify RFC
6598 shared/CGNAT space (100.64.0.0/10) as is_private (it is "shared", not
"private"), so a public redirect into 100.64.0.1 passed the per-hop guard
and still issued the request to a potentially internal CGNAT service.

not is_global would also exclude it, but only on CPython 3.11.10+/3.12.4+/
3.13+; the CI matrix runs 3.11/3.12, so reject the range explicitly to stay
correct across patch levels and the 3.14 runtime image. Default local-first
mode is unchanged. Adds strict-mode coverage for shared, non-global, and
public targets.

* docs(url-safety): correct CGNAT is_global rationale in strict-mode comment

The prior comment claimed `not is_global` catches 100.64.0.0/10 only on
CPython 3.11.10+/3.12.4+/3.13+. That is inaccurate for CGNAT: is_global
is False for 100.64.0.1 on every supported version (verified 3.10-3.14).
The version-fragility applies to other ranges gh-113171 touched, not CGNAT.
The explicit range reject is still the right choice; restate the reason as
is_private not covering shared space, and not coupling strict mode to
is_global's broader, cross-version definition. No behavior change.

Subject: [PATCH 042/180] refactor(routes): move note domain into routes/note/
 subpackage (#5236)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Slice 2f of the route-domain reorganization (#4082/#4071, per
specs/architecture-runtime-inventory.md §6.3). Moves note_routes.py into
routes/note/, leaving a backward-compat sys.modules shim at the old path.
Pure file reorganization, no behavior change.

The shim uses sys.modules replacement (same pattern as the merged gallery
#4903, research #4975, memory #5007, history #5090, and contacts #5227
slices) so that `import routes.note_routes`, `from routes.note_routes import
X`, `importlib.import_module(...)`, and the `import ... as note_routes` +
`monkeypatch.setattr(note_routes, "SessionLocal", ...)` pattern used by
test_note_reminder_fire_scope.py / test_notes_fail_closed_auth.py all
operate on the same module object the application uses.

The canonical module does NOT depend on the shim — routes/note/note_routes.py
imports only from core/, src/, and stdlib. The outbound email cross-domain
imports (routes.email_routes._get_email_config, routes.email_helpers.
_send_smtp_message) are function-local lazy imports that keep resolving
through the email module's own path (email is not yet migrated).

One source-introspection test site repointed to the new canonical path:
- test_model_helper_owner_scope.py (shared with history; history entry
  already repointed in #5090, note entry repointed here)

Adds tests/test_note_routes_shim.py to pin the sys.modules shim contract
(legacy and canonical paths resolve to the same module object; monkeypatch
via legacy alias reaches the canonical module).

Verified: compileall clean; full suite 4487 passed, 3 skipped.

 # Architecture Runtime Inventory
 
 > **Purpose**: Phase 0 planning baseline for codebase readability improvements (#4071).
-> **Parent issue**: [#4082](https://github.com/pewdiepie-archdaemon/odysseus/issues/4082)
+> **Parent issue**: [#4082](https://github.com/odysseus-dev/odysseus/issues/4082)
 > **Last updated**: dev@b58af42 | 2026-06-16
 > **Status**: Draft — to be reviewed before follow-up slices open.
 > **Snapshot basis**: Importer / file / import-line counts are refreshed to `dev@b58af42` (2026-06-16) and are recomputable via the commands in §3.4. **Line counts** in §2.1 / §2.2 are a snapshot from an earlier baseline and drift as `dev` moves — recompute any of them with `wc -l <file>`. This inventory tracks structure and risk, not live metrics.

Subject: [PATCH 044/180] refactor(routes): move cleanup domain into
 routes/cleanup/ subpackage (#5658)

Slice 2g of the route-domain reorganization (#4082/#4071). Moves
cleanup_routes.py into routes/cleanup/, leaving a backward-compat
sys.modules shim at the old path. Pure file reorganization, no behavior
change.

The shim uses sys.modules replacement so string-targeted
monkeypatch.setattr("routes.cleanup_routes.*", ...) in
test_cleanup_owner_scope.py reaches the canonical module.

Canonical module imports only from src/ and stdlib (zero internal
routes/ coupling). Zero source-introspection landmines.

Adds tests/test_cleanup_routes_shim.py to pin the sys.modules shim
contract. Verified: compileall clean; targeted tests pass.

Subject: [PATCH 045/180] refactor(routes): move admin_wipe domain into
 routes/admin_wipe/ subpackage (#5659)

Slice 2h of the route-domain reorganization (#4082/#4071). Moves
admin_wipe_routes.py into routes/admin_wipe/, leaving a backward-compat
sys.modules shim at the old path. Pure file reorganization, no behavior
change.

The shim uses sys.modules replacement so the `import ... as
admin_wipe_routes` + `monkeypatch.setattr(admin_wipe_routes, "SessionLocal",
...)` / `"require_admin"` pattern in test_admin_wipe_gallery.py reaches
the canonical module.

Canonical module imports only from core/, src/, and stdlib (zero internal
routes/ coupling). Zero source-introspection landmines.

Adds tests/test_admin_wipe_routes_shim.py to pin the sys.modules shim
contract. Verified: compileall clean; targeted tests pass.

Subject: [PATCH 046/180] refactor(routes): move compare domain into
 routes/compare/ subpackage (#5660)

Slice 2i of the route-domain reorganization (#4082/#4071). Moves
compare_routes.py into routes/compare/, leaving a backward-compat
sys.modules shim at the old path. Pure file reorganization, no behavior
change.

The shim uses sys.modules replacement so the `import ... as cr` +
`monkeypatch.setattr(cr, "SessionLocal", ...)` / `"_owned_endpoint_by_url"`
/ `"_owned_endpoint_by_id"` pattern in test_endpoint_owner_scope_followup.py
reaches the canonical module.

Canonical module imports only from core/, src/, and routes.session_routes
(zero dependency on the legacy shim). One source-introspection test site
repointed: test_endpoint_owner_scope_followup.py (shared with other domains;
only the compare entry repointed here).

Adds tests/test_compare_routes_shim.py to pin the sys.modules shim
contract. Verified: compileall clean; targeted tests pass.

Subject: [PATCH 047/180] ci: add CodeQL advanced setup to scan pull requests
 before merge (#5250)

* ci: add CodeQL advanced setup to scan pull requests before merge

* ci(codeql): preserve scheduled scans

Add a weekly advanced-setup scan and update the security CI guide so default setup remains disabled.

-4. Under **Code scanning**, use **Set up -> Default** for CodeQL. GitHub then
-   runs CodeQL as a dynamic workflow without the fork-token limitations that
-   affect checked-in advanced workflows.
-
-   Do not also add a checked-in CodeQL workflow while default setup is enabled:
-   GitHub rejects advanced CodeQL uploads when default setup is active. If the
-   project later needs an advanced CodeQL workflow, disable default setup first
-   and keep only one CodeQL publishing path active.
+4. Under **Code scanning**, keep **Default setup** disabled. CodeQL is
+   configured by `.github/workflows/codeql.yml`; enabling default setup at the
+   same time causes GitHub to reject uploads from the checked-in workflow.
 
 ## Keeping it current

Subject: [PATCH 050/180] fix(config): forward Google email OAuth settings
 through Compose (#5650)

* fix(config): forward Google OAuth env vars into Docker container and document setup

GOOGLE_OAUTH_CLIENT_ID, GOOGLE_OAUTH_CLIENT_SECRET, and GOOGLE_OAUTH_REDIRECT_URI
were read by the app but never forwarded through docker-compose.yml's explicit
environment allowlist, causing the "not set" error even when the vars existed in .env.

Also adds a documented section to .env.example with step-by-step GCP setup instructions
so users know where to get the credentials.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(config): cover OAuth in standalone compose files

* test(config): parse OAuth compose service env

* test(config): keep checkout skip wording neutral

Subject: [PATCH 051/180] fix(email): test saved OAuth accounts through shared
 transports (#5653)

* fix(email): use XOAUTH2 in test-connection for Google OAuth accounts

The test-connection endpoint was password-only and had no awareness of
OAuth accounts. For Google-connected accounts this caused two failures:
- IMAP: "Need IMAP host, username, and password" because imap_pass is
  empty (no password is stored for OAuth accounts)
- SMTP: 535 BadCredentials because smtp.login() was called with an
  empty password instead of an XOAUTH2 token

Fix: include oauth_provider and token fields in saved_body when hydrating
from the DB, then use conn.authenticate("XOAUTH2") / smtp.auth("XOAUTH2")
for Google accounts in both the IMAP and SMTP test paths, mirroring what
_send_smtp_message already does for real sends.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* test(email): add OAuth2 tests for test-connection endpoint

Covers the XOAUTH2 changes made to routes/email_routes.py:
- Google OAuth accounts must not be rejected with 'Need IMAP host,
  username, and password' (no stored password for OAuth accounts)
- IMAP and SMTP test paths must use conn.authenticate('XOAUTH2')
  for Google accounts
- Password accounts must still use conn.login() / smtp.login()

* fix(email): bind OAuth account tests to Google transport

+"""Tests for Google OAuth2 support in the /api/email/accounts/test endpoint.
+
+Covers the changes made to routes/email_routes.py:
+
+- test_account_config: OAuth accounts must not require a stored password.
+- IMAP and SMTP test paths must use XOAUTH2 for Google accounts.
+- Password accounts must still use conn.login() / smtp.login().
+
+These tests use only in-memory SQLite (via SQLAlchemy) and mock network
+objects — no live email server or real OAuth credentials are needed.

Subject: [PATCH 053/180] fix(rag): skip hidden and junk directories when
 indexing (#5633)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(rag): skip hidden and junk directories when indexing (#5559)

index_personal_documents walked the whole tree with no pruning, so
pointing RAG at a real-world folder silently swept in .obsidian/ plugin
JS, .git/ internals, node_modules/, and __pycache__/ — multiplying
indexing time and polluting retrieval with junk chunks.

Prune hidden directories and well-known junk directories from the walk,
and skip hidden files. The explicitly passed root is exempt, so a user
who deliberately indexes a hidden directory still gets its contents.

* fix(rag): prune hidden/junk dirs in the keyword index too, via a shared helper

The #5559 fix pruned only VectorRAG.index_personal_documents (the vector index).
The parallel keyword index built by PersonalDocsManager.refresh_index ->
load_personal_index walked the same tree unpruned, so .obsidian/, .git/,
node_modules/ etc. still swept into keyword retrieval and the file listing —
the 'end-to-end' guarantee was only half true.

Single-source the pruning policy in src/index_walk (prune_index_dirs +
is_indexable_file) and use it from both walkers so they cannot drift again.
The junk-dir match is now case-insensitive, so a Node_Modules on a
case-insensitive filesystem is pruned too.

Tests: keyword-path regressions covering hidden/junk dirs, hidden files, junk
at depth (not just top level), case-insensitive junk, and the explicit-hidden-
root exemption. The existing vector tests still pass against the shared helper.

If they DON'T name one, the tool defaults to the cookbook's currently-selected server (NOT localhost). When there are multiple servers and it's genuinely ambiguous which they mean, call `list_cookbook_servers` and ask. Only download to localhost when the user explicitly says "locally" / "on this machine" (pass `local=true`).

Do NOT invent modules like `diffusers_api_server`, and do NOT use bash/ssh/pip directly. The Cookbook route copies `scripts/diffusion_server.py` to remote hosts and registers the image endpoint.

   • Launching a model the user names ("serve minimax m2.7 on gpu-box") with NO preset → `serve_model {repo_id, cmd, host}`. The cookbook route OWNS tmux session creation AND state-file registration AND UI live-refresh — bypassing it produces an orphan the UI can never see. After launching, call `list_served_models` to verify readiness. If it reports a diagnosis and suggested adjusted command, retry with `serve_model` using that command instead of asking the user to debug raw tmux logs.
   • Adopting an already-running tmux session (someone or a prior bash launch started a server, but it's not in the cookbook) → `adopt_served_model {host, tmux_session, model, port}`. This registers it in cookbook_state.json AND adds it as a chat endpoint so the user can pick it in the model dropdown. Use this whenever you find a running server that the cookbook doesn't know about.
   • After ANY successful serve (preset or raw or adopted), the cookbook's serve flow auto-adds the model as an endpoint. If for some reason it didn't (e.g. the launch was external), call `adopt_served_model` to fix both at once, or `manage_endpoints` with action=add to register the URL manually.

Slice 2j of the route-domain reorganization (#4082/#4071). Moves
search_routes.py into routes/search/, leaving a backward-compat
sys.modules shim. Pure file reorganization, no behavior change.

Subject: [PATCH 066/180] fix(ci): clear review label when issues close (#5813)

The issue-close lifecycle change is narrowly scoped and correct. Closed issues remove the stale \`ready for review\` label and return before normal validation can restore it. Focused regressions cover closure and subsequent edits to a closed issue.

The branch was updated onto current \`dev\`. The focused test, merged-result validation, diff checks, and GitHub CI passed. No blocking review threads remain.

Subject: [PATCH 067/180] fix(skills): use utility model for skill tests
 instead of chat default (#5746)

Skill tests are background automation tasks (like auto-naming and
memory audit) and should use the configured utility model. Previously
they resolved via resolve_endpoint("default") which returned the
chat model, bypassing the utility model entirely.

This completes the sweep started in PR #4027 which fixed auto-naming
and memory audit but missed skill tests.

Subject: [PATCH 068/180] fix(skills): replace deprecated utcnow in skill
 timestamp helper (#5777)

* fix(skills): replace deprecated utcnow in skill timestamp helper

_now_iso() builds the 'created' value in skill frontmatter. datetime.utcnow()
returns a naive datetime and has been deprecated since Python 3.12, scheduled
for removal. Switch to the timezone-aware datetime.now(timezone.utc), keeping
the serialized YYYY-MM-DDTHH:MM:SSZ shape unchanged so existing skill files
keep parsing.

timezone.utc is used rather than the datetime.UTC alias, which is 3.11+ only.

Adds regression tests covering the deprecation, the serialized shape, and
UTC correctness under a non-UTC local timezone -- the last guards against a
bare datetime.now(), which yields the same shape but local wall time.

Fixes #5697

* test(skills): skip timezone mutation where unsupported

Subject: [PATCH 069/180] fix(markdown): restore extracted blocks verbatim so
 $& and $$ survive (#5768)

The placeholder-restore pass in mdToHtml put code, math, mermaid and
allowed-HTML blocks back with a string replacement, so String.replace read
`$&`, `` $` ``, `$'` and `$$` in the *replacement* as substitution patterns.
A fenced block containing them rendered corrupted: `$&` re-inserted the
placeholder (`perl -pe 's/world/$& again/'` became
`s/world/___CODE_BLOCK_0___amp; again/`), `` $` `` and `$'` spliced in the
surrounding document, and `$$` collapsed to a single `$`.

Pass a function replacer at all four sites, matching the inline-code site
below them, which was already fixed this way. A function's return value is
inserted verbatim with no `$` interpretation.

The inline-code comment claimed `echo $1` would be read as a back-reference;
with a string search value there are no capture groups, so `$1` is already
literal. Reworded to name the four sequences that do corrupt.

Fixes #5663

Subject: [PATCH 070/180] fix(llm): omit temperature for major-only Opus ids
 (claude-opus-5) (#5761)

The version pattern in _anthropic_rejects_temperature() required a minor
component, so major-only ids like `claude-opus-5` never matched and the
guard reported that the model accepts `temperature`. Anthropic rejects the
field outright on Opus 4.7+, so every such call returned HTTP 400 and the
stream aborted with zero tokens ("the model returned an empty response").

Make the minor optional and read a missing minor as `.0`. The major is also
capped at 1-2 digits with a no-trailing-digit lookahead, mirroring the
minor: once the minor is optional, a greedy major would swallow the date in
`claude-3-opus-20240229` and read it as version 20240229, dropping
temperature from a model that accepts it.

Fixes #5753

Subject: [PATCH 073/180] refactor(routes): move vault domain into
 routes/vault/ subpackage (#5780)

Slice 2k of the route-domain reorganization (#4082/#4071). Moves
vault_routes.py into routes/vault/, leaving a backward-compat
sys.modules shim. Pure file reorganization, no behavior change.

Subject: [PATCH 074/180] refactor(routes): move webhook domain into
 routes/webhook/ subpackage (#5781)

Slice 2l of the route-domain reorganization (#4082/#4071). Moves
webhook_routes.py into routes/webhook/, leaving a backward-compat
sys.modules shim. Pure file reorganization, no behavior change.
One source-introspection test repointed (test_api_chat_security.py).

Subject: [PATCH 075/180] refactor(routes): move document domain into
 routes/document/ subpackage (#5885)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Slice 2m of the route-domain reorganization (#4082/#4071, per
specs/architecture-runtime-inventory.md §6.3). Moves document_routes.py
(1810 lines) and document_helpers.py (243 lines) into routes/document/,
leaving backward-compat sys.modules shims at the old paths. Pure file
reorganization, no behavior change.

Both shims use sys.modules replacement so the `import ... as droutes` +
`droutes.SessionLocal = ...` / `monkeypatch.setattr(droutes, ...)` pattern
in multiple tests, and the `sys.modules.pop("routes.document_helpers")` +
re-import pattern in test_security_regressions.py, all reach the canonical
modules.

The canonical document_routes.py imports helpers from the canonical path
(routes.document.document_helpers), not the legacy shim.

Three source-introspection test sites repointed to the new canonical path:
- test_imap_mailbox_quoting.py
- test_model_helper_owner_scope.py
- test_vision_owner_scope.py (shared with other domains; document entry repointed)

Adds tests/test_document_routes_shim.py to pin the sys.modules shim contract
for both modules.

Verified: compileall clean; full suite 4789 passed, 3 skipped.

Subject: [PATCH 076/180] fix(integrations): pin api_call to the SSRF-validated
 IP (#5727)

* fix(integrations): pin api_call to the SSRF-validated IP

execute_api_call runs check_outbound_url on the target, but that guard only
resolves the host to answer (ok, reason) and hands back no address. The request
right after it opened a plain httpx.AsyncClient, which resolves the host again at
connect time. A base_url host on a low TTL can pass the guard as a public IP and
then flip to 169.254.169.254 for the connect, so the call lands on cloud metadata
with the integration's stored auth headers attached.

Resolve once, remember the IPs the guard actually validated, and pin the client's
socket to that set through a small AnyIO-backed transport. SNI and the Host header
still come from the URL, so TLS and vhost routing are unchanged; connect-time
fallback stays inside the approved address set over one shared deadline. This is
the same pinning the webhook sender and web-fetch paths already do -- api_call was
the last outbound path that skipped it.

Fixes #5513

* fix(integrations): de-duplicate the pinned IP list

_default_resolver calls getaddrinfo(host, None) with no socktype filter, so
glibc returns one record per socktype and a single-homed host comes back three
times over. _validated_ips kept every entry, so the transport pinned the same
address repeatedly and the connect fallback could spend its shared deadline
retrying one dead address instead of moving on to a genuinely different one.

Windows getaddrinfo collapses those duplicate records, which is why the
ip-literal pin test only failed on CI and not locally.

Subject: [PATCH 078/180] fix(memory): don't let an unreadable store get
 overwritten with an empty one (#5831)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(memory): don't let an unreadable store get overwritten with an empty one

load_all() answered a failed read the same way it answered an empty store:
with []. Every mutation path is a read-modify-write (load the whole file,
change it, save it back), so a failed read became

    load_all() -> []  ->  [].append(new)  ->  save([new])

and save() is atomic, so the replacement stuck.

The case that actually destroys data is a store that is READABLE but not
parseable - a truncated file, or one holding {} instead of []. Nothing
obstructs the write, so adding a memory returns HTTP 200 and every memory
already stored is gone. Verified end-to-end against a running instance: on the
current code a truncated memory.json plus one add leaves the file holding only
the new entry. Truncation is reachable - core/database.py rewrites memory.json
during migration with a plain open(.., "w") + json.dump, which is not atomic.

A live exclusive lock is not the dangerous case: it blocks the read and the
os.replace alike, so the save fails too and the store survives. That path
currently 500s and loses nothing.

_read_entries() now returns [] only when the file genuinely does not exist and
raises MemoryStoreUnreadable for every other failure, including a store that
parses but is not a JSON array. load_all() keeps the old lenient behaviour so
display, search and context injection still degrade quietly instead of
breaking chat. The read-modify-write callers switch to load_all_for_update(),
which propagates the error: the memory routes turn it into a 503 and change
nothing, backup import refuses rather than saving only the incoming rows, and
auto-extraction and the audit merge skip the write. The audit merge mattered
most - it rebuilds the whole file from one owner's slice plus everyone else's
rows, so an empty read there dropped every other tenant's memories.

The corrupt-JSON path still gets its one shot at the legacy memory.txt
migration before raising, so that recovery is unchanged.

The two updated fakes gained load_all_for_update because the real class has it;
MagicMock would otherwise hand the import path a Mock instead of the seeded list.

Fixes #5673

* fix(memory): fail closed on the remaining read-modify-write add paths

The strict loader landed with the routes, the backup import and the extractor
converted, but three read-modify-write sinks still called load_all(), which
degrades an unreadable store to []. Two of them are the paths users actually
reach, so the data loss in #5673 stayed reproducible:

- src/ai_interaction.py do_manage_memory, action "add" — reached from ordinary
  chat via src/tool_execution.py:793 -> dispatch_ai_tool. "Remember that I
  prefer X" against an unreadable store wrote a one-entry file over it and
  reported success.
- mcp_servers/memory_server.py, action "add" — the same shape through
  _scope_entries(), registered as a built-in in src/builtin_mcp.py.
- src/memory_provider.py NativeMemoryProvider.remember and .delete — wired
  into app state in src/app_initializer.py but not consumed outside tests yet,
  converted here so the pattern is uniform before it goes live.

The MCP server takes _scope_entries(for_update=True) so list keeps the lenient
read. The edit and delete branches on both tool paths were already fail-closed
by accident — an empty view matches nothing and returns before the save — so
they are left alone.

The three new tests drive the real entry points rather than replaying the
shape, and use a truncated store, which is the case that reads back fine so
nothing stops the save. Each asserts memory.json is byte-identical afterwards;
all three fail on the previous commit with the store overwritten.

+"""A memory store that cannot be READ must never be overwritten (issue #5673).
+
+`MemoryManager.save` is atomic, and the add/import/extract paths are all
+read-modify-write: load the whole store, append, save it back. `load_all`
+used to answer a *failed read* with `[]` — indistinguishable from "no
+memories" — so a failed read turned into
+
+    load_all() -> []  ->  [].append(new)  ->  save([new])
+
+which atomically replaced the entire store with one entry.
+
+The trigger that actually bites is a store that is **readable but not
+parseable** — a truncated file, or one holding `{}` instead of `[]`. Nothing
+obstructs the write, so the request succeeds with HTTP 200 and every existing
+memory is destroyed silently. Truncation is reachable: `core/database.py`
+rewrites memory.json during migration with a plain `open(..., "w")` +
+`json.dump`, which is not atomic.
+
+A live exclusive lock is NOT the dangerous case: it blocks the read and the
+`os.replace` alike, so the save fails too and the store survives (verified
+end-to-end — clean dev returns 500 there and loses nothing).
+
+`load_all_for_update` is the strict loader those callers now use: it raises
+`MemoryStoreUnreadable` rather than reporting an empty store.

Subject: [PATCH 082/180] fix(tool_parsing): require a pipe on the Qwen bare
 end marker (#5829)

The `end` branch of _QWEN_BARE_MARKER_RE had both pipes optional
(`\|?end\|?`), so it also matched a bare `end` between whitespace and
replaced it with a space. Messages containing Ruby, Lua or shell code that
closes a block with a lone `end` had those lines deleted, and ordinary prose
lost the word too.

Require at least one pipe so only real turn markers match; `|end`, `end|`,
`|end|` and `/|end|` strip exactly as before. Applied to the duplicated
pattern in static/js/chatRenderer.js as well.

Fixes #5547

Subject: [PATCH 083/180] fix(chat): stop ArrowUp from eating an unsent
 multi-line prompt (#5875)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

static/app.js carried a near-verbatim copy of the prompt-recall logic in
static/js/composerArrowUpRecall.js, wired as a second capture-phase
keydown listener on the same #message textarea. The copy omitted the
draft guard the module has: it called preventDefault() and
stopImmediatePropagation() unconditionally, then recalled history[0]
over whatever the user had typed.

Because it stopped immediate propagation, the copy won regardless of
registration order — if it ran first the module never saw the event, and
if it ran second the module had already declined to stop propagation on
an unmatched draft. The guard at composerArrowUpRecall.js:109 was
unreachable on the real page, so ArrowUp on a multi-line draft replaced
it with the last sent prompt instead of moving the caret up a line.

Delete the duplicate. The module keeps ownership of ArrowUp/ArrowDown
recall, which is the behavior MODULE_SUMMARY.md documents ("on an empty
composer") and the behavior tests/test_composer_arrow_up_recall_js.py
already pins via test_non_empty_composer_does_not_recall and
test_multiline_caret_navigation_preserved.

Also correct a stale comment in the module that described the deleted
behavior and contradicted the guard 35 lines above it, and add a
regression test asserting app.js does not reintroduce a second handler.

Fixes #5862

Subject: [PATCH 084/180] fix(session): restore session URL hash writes
 (removed in cf4e240a) (#5872)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix: restore session URL hash writes (removed in cf4e240a)

Restores history.replaceState() calls in selectSession() and
materializePendingSession() that were dropped during the July 23 merge.
Without these, chat URLs never update the address bar hash, making
sessions unshareable and causing bare-URL reloads to land on the
welcome screen instead of restoring the last active chat.

Root cause: selectSession() had its hash-write deliberately removed;
materializePendingSession() lost its during a larger refactor that
added the stale-response and incognito guards.

Fixes #5870 (upstream)

* fix: session URL hash lost when sending message mid-stream

Two independent bugs caused the session hash to disappear from the URL:

Bug 1 — ReferenceError in catch block silently killed error recovery
  In handleChatSubmit, two const variables (streamingTTS at line 1922 and
  abortCtrl at line 1741) were declared inside the try block but referenced
  in the catch block. Since const is block-scoped in JavaScript, they were
  undefined in catch, causing a ReferenceError that silently aborted the
  error handler. This prevented materializePendingSession() from ever being
  called, so no hash was written to the URL.
  Fix: Hoisted both as let declarations before the try { block.

Bug 2 — Dual sessions.js ES module instances with mismatched state
  app.js imported sessions.js with a version query string
  (?v=20260722ctxheader4) while every other module imported ./sessions.js
  without one. The browser treated them as different URLs, creating two
  separate module instances with independent _pendingChat and
  currentSessionId state. createDirectChat() set pending on one instance
  while handleChatSubmit() checked hasPendingChat() on the other — so the
  pending session never materialized.
  Fix: Removed the version query string from the sessions.js import in
  app.js and from the modulepreload + script tags in index.html. All
  modules now share a single sessions.js instance.

Bonus guard: _adoptOpenedSessionBeforeAutoCreate() now checks
hasPendingChat() before adopting a stale DOM-active session, preventing
the send path from landing in the wrong session when a New Chat is pending.

Subject: [PATCH 085/180] Fix #5870: stale skills panel data on tab reopen
 (#5876)

Remove early-return guard in loadSkills() that skipped both API re-fetch
and renderSkillsList() when the Skills tab was reopened after first load.
The cascade entrance animation is already handled inside renderSkillsList()
via _cascadeNext, so the guard was unnecessary and caused deleted/edited
skills to remain visible until a full page reload.

Subject: [PATCH 086/180] fix(brain): give the Add Memory form a submit button
 and reliable Enter handling (#5830)

The Brain > Add tab rendered only a text input and category select with no
submit control, and Enter submission relied on a deprecated keypress
listener that is not guaranteed to fire, so the form could not be
submitted at all (#5828).

Add a labelled submit button styled like the neighbouring Skill Import
button (theme-io-btn, inline SVG icon), switch the Enter handler to
keydown with preventDefault, ignore IME composition, and pin both submit
paths with a source-level regression test.

Fixes #5828

Subject: [PATCH 089/180] fix(email): make unread opens one authoritative IMAP
 operation (#5923)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(email): mark opened messages seen in one IMAP operation

* fix(email): collapse unread opens and ignore stale responses

* fix(email): send seen flags as an IMAP flag list

Wrap the authoritative \\Seen STORE operand in parentheses so strict IMAP servers such as GreenMail accept both cache-miss and cached-open transitions. Tighten the focused fake IMAP contract to reject the previously emitted bare flag atom.

* fix(email): guard stale authoritative opens

* fix(email): report a failed \Seen instead of withholding the message

The authoritative-open contract made a failed STORE fatal to the read: the
cold path raised after the body was already fetched and parsed, and the
cached path discarded an in-memory message to return
{"error": "Failed to mark email read"}. A transient IMAP failure therefore
turned a readable message into one that could not be opened at all.

Being authoritative should mean the reported flag state is truthful, not
that the body is withheld. The read now always returns the message and
carries mark_seen_failed so the client can roll its optimistic unread
marker back:

- _read_email_sync logs and reports a rejected STORE rather than raising,
  and only writes the local index/list-cache transition when the provider
  accepted it, so local state cannot drift ahead of the mailbox.
- A mailbox that refuses a read-write SELECT (shared archives, some
  provider folders) falls back to a read-only selection and reports the
  flag failure instead of failing the open.
- The route strips mark_seen_failed before caching, so a one-off failure is
  never replayed to later readers.
- mark_seen now defaults to False on _read_email_sync. It was inert before
  this branch and now mutates provider state; the one caller that wants it
  off already passes it explicitly.

emailInbox and emailLibrary keep the message rendered when mark_seen_failed
is set and restore the unread state, rather than showing a failed reader.

Subject: [PATCH 091/180] perf(ui): stop session loading from blocking shell
 (#5927)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* perf(ui): stop session loading from blocking shell

* fix(startup): open routes on their own data, retire the loader for good

Follow-up to review on #5927.

- Route openers are now classified by the data they actually read. Only
  /email touches the hydrated session list (its new-chat path falls back to
  the most recent session's model when no default chat is set), so every
  other route opens as soon as module wiring completes instead of queueing
  behind /api/sessions. This is the deferred-route half of #5926, which the
  first pass left unimplemented.
- index.html's 5s fallback removes the loader node again. Leaving it in the
  DOM indefinitely kept _shouldPreserveStartupComposer true forever on a
  hung /api/sessions, so the composer stopped clearing on session switch.
- A missing session module settles hydration instead of leaving the sidebar
  on "Loading chats…" and dropping the user's route on the floor.
- Startup sequencing moved to static/js/startupShell.js so it can be run by
  tests. The source-text assertions in test_startup_shell_session_loading.py
  are replaced by node-driven behavioural tests, per tests/TESTING_STANDARD.md.
- Reverted the unrequested loader a11y rework, removed the duplicated inert
  writes (the module stops the wave interval through a callback), and moved
  the bootstrap row's inline styles into .session-list-bootstrap.

* fix: preserve session bootstrap failure state

Subject: [PATCH 092/180] fix(history): defer full transcript hydration to
 model sends (#5929)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(history): defer full hydration to model sends

* fix(session): key hydration on real rows, fork through get_session

Two regressions from the display/model-context split, both reproducible
against dev.

The hydration gate compared the cached transcript against the
denormalized sessions.message_count column. That column drifts in normal
operation — _persist_message swallows a failed insert while add_message
has already appended in memory, so the next successful persist writes
rows+1 — and _db_to_session re-read the same column after each reload, so
the shortfall never closed. Every send, edit, delete and truncate on a
warm session re-selected the whole message table: the cost this change
set out to remove, relocated onto the hot path. The other direction was
just as bad — a persist for an uncached session writes message_count = 0,
and a stale-low counter with a partly filled cache meant no hydration at
all and a silently truncated transcript for the model.

sync_session_metadata now reconciles message_count against COUNT(*) on
chat_messages (one indexed count inside the connection it already opens),
and _db_to_session trusts the rows it just loaded. A hydrate always
closes the gap, so the next read is a cache hit.

fork_session read session_manager.sessions directly and never hydrated.
keep_count indexes into source.history, and display pagination no longer
fills that cache, so forking after a restart returned HTTP 200 with an
empty conversation and no error surfaced. It goes through get_session
now.

_hydrate_session_history_from_db is gone with its helper: get_session is
the hydration seam, and rebuilding session.history from raw rows in the
display fallback overwrote the parsed multimodal content and the _db_id
edit/delete keys that had just been set.

Tests drive a real SessionManager over a temp DB instead of a stub that
only proved the stub hydrates — both drift directions, the send path
warm and cold, and a fork taken after a restart. All five fail without
this change. The brittle SQL-text assertions are dropped; the page
bounds are already proven by the response body.

* fix(history): route pagination through canonical handler

Subject: [PATCH 093/180] perf(chat): batch live thinking rendering and bound
 timer updates (#5931)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* perf(chat): batch live thinking DOM updates

* test(chat): cover live thinking scheduler lifecycle

* fix(chat): guard background stop-state, restore live thinking text, drop source-text tests

- _closeOpenThinkingMarkup no longer overwrites currentAccumulated for
  backgrounded streams. It now mirrors the guard the delta path already uses
  (`if (!_isBg) currentAccumulated = accumulated`). Without it a backgrounded
  stream's text is written into the foreground session's stop-state, which
  abortCurrentRequest and detachCurrentStream then put in the wrong bubble.

- Split _extractLiveThinkingText into _liveThinkingText (strip every think tag)
  and _closedThinkingText (via extractThinkingBlocks). Slicing from the first
  <think> to the first </think> pinned the live box to "The" for the rest of the
  stream on the `<think>The</think>` + untagged-thinking pattern that the
  hasUnclosedThink detection deliberately keeps streaming through.

- The background transition now flushes with rich:true, so a stream that
  backgrounds mid-thinking isn't left as pre-wrap plain text permanently.

- Move the throttle to static/js/liveThinkingThrottle.js and import it. The
  .mjs suite imports the module instead of slicing it out of chat.js with
  vm.runInNewContext and marker comments.

- Replace the source-text assertions in tests/test_live_thinking_scheduler_js.py
  with behavioral coverage, per tests/TESTING_STANDARD.md. The .mjs suite grows
  from 3 to 6 cases.

- Collapse the duplicated tool_start/agent_step finalizers into one
  _endLiveThinkingSection().

* fix(chat): hoist thinking teardown out of the try block so catch can reach it

In an ES module a function declared inside `try { }` is scoped to that block,
and `catch` is a sibling scope rather than a nested one. _closeOpenThinkingMarkup
was declared inside the try and called from catch, so the call threw
ReferenceError and killed the rest of the error path: the stream never
finalized and the thinking block was never torn down.

Declare _closeOpenThinkingMarkup and a new _endThinkingOnTerminalPath next to
the existing _flushLiveThinking / _cancelLiveThinkingWork outer lets and assign
them inside the try, which is the pattern those two already use for exactly
this reason.

Verified against a live stream in a browser: before, clicking stop mid-thinking
logged "_closeOpenThinkingMarkup is not defined" and left no finalized thinking
section; after, the block collapses to "View thinking process" correctly.

* perf(chat): extract live thinking at commit cadence

* fix(chat): bound live thinking work

* test(chat): update stream invariant assertions

 | **`chatRenderer.js`** | Message DOM construction: `addMessage`, role labels, model route labels, color coding, footers, metrics, code blocks, sources boxes (`web`/`research`/`RAG`), findings box, images, report links, ask-user cards, welcome screen, and transcript utilities. |
 | **`streamingRenderer.js`** | Incremental streaming renderer used by `chat.js`. Freezes finalized DOM blocks and only re-renders the growing tail to avoid flicker and O(N²) re-parsing. |
 | **`streamingSegmenter.js`** | Splits a token stream into display units (text vs code fences) for `streamingRenderer.js`. |
+| **`liveThinkingThrottle.js`** | Trailing-edge coalescer for the live thinking block in `chat.js`: one DOM commit per 100 ms carrying the latest reasoning text, with `flush`/`cancel` for terminal and session-switch paths. |
 | **`slashCommands.js`** | Slash-command registry (`/help`, `/setup`, etc.), parsing, and dispatch handlers. Exported functions are consumed by `chat.js` and `slashAutocomplete.js`. |
 | **`slashAutocomplete.js`** | Composer autocomplete popup for `/` commands. |
 | **`composerArrowUpRecall.js`** | Recall last user message with `↑` on an empty composer. |

+//   cancel()       drop the timer AND the pending value — nothing lands later

Subject: [PATCH 094/180] refactor(routes): move mcp domain into routes/mcp/
 subpackage (#5899)

Slice 2o of the route-domain reorganization (#4082/#4071). Moves
mcp_routes.py (697 lines) into routes/mcp/, leaving a backward-compat
sys.modules shim. Pure file reorganization, no behavior change.

The shim uses sys.modules replacement so sys.modules.pop + re-import,
monkeypatch.setattr(mcp_routes, "MCP_OAUTH_DIR", ...), and __file__
introspection in test_security_regressions.py all reach the canonical
module. One source-introspection path string repointed (line 1001).

Canonical module imports only from core/, src/, and stdlib (zero internal
routes/ coupling). Adds tests/test_mcp_routes_shim.py.

Verified: compileall clean; full suite 4804 passed, 3 skipped.

Subject: [PATCH 095/180] fix(core): stop atomic writes from colliding on a
 constant PID suffix (#5721)

atomic_write_json/atomic_write_text build their temp filename as
"{path}.tmp.{os.getpid()}". os.getpid() is constant for the life of a
process, so it only ever distinguishes concurrent writers that live in
different OS processes. Odysseus runs as a single long-lived process
per container, so two concurrent writers to the same path (e.g. two
request handlers racing a settings save) always compute the identical
temp path. Whichever finishes os.replace() first removes the shared
tmp file out from under the other, which then raises FileNotFoundError
on its own os.replace() instead of landing its write.

Fix: derive the temp suffix from uuid4() instead of the PID, so every
call gets a distinct temp path regardless of process/thread identity.

routes/prefs_routes.py's _save() had an independent, hand-rolled copy
of the exact same PID-suffix logic (not the shared core.atomic_io
helper other routes already use, e.g. routes/auth_routes.py) with the
same bug. Replaced it with a call to atomic_write_json.

Fixes #5596

Subject: [PATCH 096/180] fix(email): derive the Google OAuth redirect URI
 scheme from the request (#5995)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both the authorize and callback routes built the redirect URI with a
hardcoded `http://` and the Host header. Behind any TLS terminator that
produces `http://host:443/api/email/oauth/google/callback` — the wrong
scheme and, on a split-port setup, a dead port. Google then refuses the
authorize request or the token exchange, so OAuth email is unusable on
every HTTPS deployment unless GOOGLE_OAUTH_REDIRECT_URI is pinned by hand.

uvicorn's proxy-headers middleware already rewrites the scheme from
X-Forwarded-Proto for trusted proxies (on by default, trusting 127.0.0.1),
so request.url.scheme is correct both directly and behind a proxy.

Google requires the callback's redirect_uri to match the authorize one
exactly, so both sites change together. An explicit
GOOGLE_OAUTH_REDIRECT_URI still wins, unchanged.

Subject: [PATCH 097/180] fix(ui): stop the whirlpool spinner animating when it
 is never attached (#5990)

_drawWhirlpool re-armed requestAnimationFrame forever whenever its element
had never been connected to the document. The grace period is there so a
spinner can keep drawing between start() and the caller appending the
element, but it had no deadline: while the element has never been connected
_wpWasConnected stays false, so the guard stays true and the else branch is
unreachable. Any caller that starts a spinner and then takes an early return,
such as an aborted request or a panel that resolved from cache, leaves a loop
redrawing an 84-segment spiral into a detached canvas at one frame per
displayed frame until the tab closes.

Put a 2 second deadline on the grace period. Callers append in the same task
as start(), so that is far more slack than any of them need. A spinner that
is actually in the document is unaffected.

Two supporting changes in the same file:

- Both self-terminate paths now call stop() instead of setting isRunning
  directly, so termination always runs one cancelAnimationFrame and never
  depends solely on inferring DOM connectivity. Both draw functions bail at
  the top when they are no longer running, and _requestFrame() clears rafId
  as the callback enters so it is a truthful "a frame is pending" flag.
- start() arms a visibilitychange listener and stop() removes it. A hidden
  tab cancels the pending frame, a re-shown tab re-arms it. Chrome throttles
  background rAF but does not reliably stop the canvas work, and owning the
  listener from start/stop means a dead spinner never leaves one behind.

Adds tests/test_spinner_stops_when_never_attached_js.py, which drives the
real module under node with a fake clock and a manual frame pump. It covers
all four exits and, importantly, the converse: a spinner that is attached
keeps running well past the grace window.

+"""Pin the self-termination contract of the canvas spinners in static/js/spinner.js.
+
+Background: the whirlpool spinner drives itself with requestAnimationFrame and
+decides whether to keep going by looking at `element.isConnected`. It used to
+re-arm forever whenever the element had *never* been connected, on the theory
+that start() runs before the caller appends the element. Callers that start a
+spinner and then take an early return - an aborted request, a panel that
+resolved from cache before the loading row was inserted - therefore left a rAF
+loop redrawing an 84-segment spiral into a detached canvas until the tab closed.
+Measured on an idle app: ~110 whirlpool frames per second with zero canvases in
+the document.
+
+These tests lock in all four exits (never attached, attached-then-removed,
+stop(), tab hidden) and, just as importantly, the one case that must NOT stop:
+a spinner that is actually on screen.
+
+Driven through `node --input-type=module` so the real module runs, same idiom as
+test_esc_menu_stack_js.py. The module source is inlined rather than imported by
+path because the repo has no `"type": "module"` in package.json; spinner.js has
+no imports of its own, so inlining is exact. A fake clock and a manual frame
+pump replace performance.now()/requestAnimationFrame, so nothing here depends on
+wall-clock time or real frame timing.

Subject: [PATCH 098/180] fix(llm): normalise Mistral structured content in
 llm_call_async (#5882)

llm_call_async returned raw list content for Mistral thinking models,
breaking callers that expect a str (e.g. auto-title). Match the sync
and streaming parsers by running list content through
_normalize_mistral_content.

Fixes #5435

Subject: [PATCH 099/180] perf(frontend): preload the two first-paint Fira Code
 faces (#5992)

The app font faces are declared in static/style.css, so the browser only
discovers FiraCode-Regular.woff2 and FiraCode-SemiBold.woff2 once the
stylesheet has parsed. On a cold load they start about 145 ms in, behind
the module graph. font-display: swap keeps that from blocking render, so
the cost is a visible swap rather than a stall, but the fetch can start
immediately instead.

Two preload hints move the request into the head. Measured cold on a
scratch instance with an empty cache, three runs per arm: request start
142-203 ms becomes 15-19 ms, response end 174-248 ms becomes 46-63 ms.
The total request count is unchanged and each face is still fetched
exactly once.

crossorigin is required even though these are same-origin: fonts are
always fetched in CORS mode, and without it the preload is discarded and
the font fetched again. Dropping the attribute produces four font entries
in the Resource Timing list instead of two.

Only Fira Code 400 and 600 are preloaded. They are the only faces first
paint uses. Inter, OpenDyslexic and Fira Code 300 stay unloaded on both
desktop and mobile, with or without a saved font preference.

Subject: [PATCH 100/180] fix(skills): stop SKILL.md frontmatter escapes
 compounding on every save (#5883)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_emit_scalar quotes a frontmatter scalar with json.dumps when it holds
punctuation that would change how the line reads back. _parse_scalar undid that
with a bare raw[1:-1]: it stripped the quotes but never decoded the escapes. So
a description containing ü was written as the escape sequence \u00fc, read
back with that escape still sitting literally in the value, and re-escaped on
the next save. The backslash run doubles every save, so a non-English skill
description degrades into backslash noise after a few edits, and the escapes are
shown verbatim in the skills list and the /skills catalog.

This is not limited to non-ASCII. Any description containing a quote takes the
same path, since the quote is itself what forces the quoted form.

Make the two halves symmetric: emit with ensure_ascii=False, since SKILL.md is
UTF-8 at both ends (skills.py reads it, atomic_write_text writes it) and the
ASCII-escaped form bought nothing; and parse double-quoted scalars with
json.loads, falling back to the previous literal reading when the value is not
valid JSON. Files already corrupted heal one level per load.

ensure_ascii=False on its own would open a smaller hole. json.dumps escapes
every C0 control character but passes NEL, LINE SEPARATOR and PARAGRAPH
SEPARATOR through literally, and parse_frontmatter reads one scalar per line via
str.splitlines(), which breaks on all three. Re-escape those three, and add them
plus the remaining splitlines characters to the set that forces a quoted scalar,
so none of them can reach the file bare.

Subject: [PATCH 102/180] fix(sidebar): keep minimized icon rail in sync with
 per-tab visibility (#5987)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(sidebar): keep minimized icon rail in sync with per-tab visibility

Per-tab visibility (Customize UI / Appearance checkboxes, stored in
localStorage under `odysseus-ui-visibility`) was only applied to the full
sidebar elements — `UI_VIS_MAP` never targeted the collapsed `#icon-rail`
launchers. So a user who turned a tab off (e.g. Email) in the full view saw
every tab reappear when minimizing the sidebar to the icon rail.

Pair each tool/section selector with its `#rail-*` counterpart (mapping
mirrors `_railToolMap`), so `applyUIVis()` hides the rail launcher too.
Admin feature-flag handling is unaffected: the features-fetch reconcile at
app.js already re-applies `applyUIVis()`, so rail launchers now track admin
disables exactly like their sidebar buttons.

Adds a static regression test asserting every customizable tab pairs its
rail button.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(sidebar): extract UI visibility into testable module

Move UI_VIS_MAP, UI_VIS_DEFAULT_OFF, and a pure resolveVisibility() into
static/js/ui_visibility.js so the icon-rail visibility rules are unit
testable without a DOM. app.js applies resolveVisibility() to the document,
replacing the ad-hoc tools-section override with an inline parent rule
(tools-section off hides every tool rail launcher). Add edge-case tests
covering per-tool off, the tools-section parent rule, parent+child combos,
email-section, and the tool-library <-> #rail-archive mapping.

Subject: [PATCH 103/180] fix(ui): stop stripping the word assistant from
 rendered text (#5974)

* fix: stop stripping the word 'assistant' from rendered text

The QWEN_BARE_MARKER_RE regex in both the Python backend (tool_parsing.py)
and JS frontend (chatRenderer.js) was matching any standalone occurrence of
the word 'assistant' separated by any whitespace, then replacing it with a
space. This caused normal English uses like 'Home assistant' to render as
'Home '.

Fixed by narrowing the word-boundary check from [\t\r\n ] (any whitespace)
to [\r\n] (line boundaries only), so only Qwen-format role-token leaks
(where 'assistant' appears alone on a line) are stripped.

* fix(tests): update bare-marker test expectations for #5971

Move 'x assistant y' from STRIPPED to KEPT (mid-sentence must survive).
Add 'Before\nassistant\nAfter' to STRIPPED (bare-marker on own line).

* fix(ui): strip whitespace-padded assistant role markers

Subject: [PATCH 104/180] fix(llm): alias tool names that collide with gpt-oss
 built-ins (#5878)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gpt-oss (harmony) ships BUILT-IN tools named python/browser, invoked
with the raw body as the argument (to=python + bare source), while
custom functions use to=functions.NAME + JSON. Exposing our own tools
under those names makes the model answer with the built-in convention:
it emits raw code, the server parses it as JSON, and the request dies
with 'error parsing tool call: raw=import sys, ...'. In streaming mode
Ollama does not report it at all — it truncates the stream, so the turn
arrives as an empty response and the agent loop reads it as a model
stall. bash collides the same way in practice.

Measured on gpt-oss:20b via Ollama /v1, fixed agentic prompt, 12 runs
per arm: python+bash as-is 2/12, python renamed 10/12, both renamed
12/12. 74 HTTP 500s were logged server-side during investigation with
zero surfaced to the client.

Rename the colliding tools on the outbound payload and map the names
back on responses. Transport-only and gated on gpt-oss: every other
model's schemas pass through untouched (asserted in tests).

Subject: [PATCH 105/180] fix(tools): parse Hermes/Qwen JSON bodies inside
 tool_call wrappers (#5887)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

parse_tool_blocks fed <tool_call> wrapper bodies only to the XML
iterators (_iter_xml_invoke/_iter_xml_direct), so the canonical
Qwen/Hermes text-mode form — a bare JSON object like
{"name": "bash", "arguments": {"command": "..."}} inside the
wrapper — parsed to zero tool blocks and the agent never executed
anything. Pattern 4d only matches OpenAI-style blobs with a literal
"function" key, which the Hermes format lacks.

Wrapper bodies are now classified first: a JSON-looking body ({ or [)
is parsed by the new _parse_json_tool_call_body, which requires an
object with a string "name" and rejects a non-object "arguments"
instead of coercing it, then converts through the same
function_call_to_tool_block used by the XML paths so aliases and
per-tool argument formatting stay uniform. JSON-looking bodies fail
closed — they are never rescanned by the XML iterators (including the
unclosed-wrapper and bare-invoke fallbacks), so XML-like text inside
JSON argument values stays data instead of selecting a different tool.
Non-JSON bodies keep the existing XML path unchanged.

Fixes #5187

Subject: [PATCH 108/180] fix(thinking): add deepseek-v4 to thinking model
 patterns (#6000)

* fix(thinking): add deepseek-v4 to thinking model patterns

deepseek-v4-flash emits reasoning_content via the API but was not
recognized in _THINKING_MODEL_PATTERNS (only deepseek-r1 and
deepseek-reasoner were listed). Add the deepseek-v4 prefix so
the model is recognized as thinking-capable.

The between-round _thinkOpen leakage was separately fixed by
PR #5931 (perf(chat): batch live thinking rendering).

Related: #3998, #5931

* test(thinking): cover DeepSeek v4 detection

Subject: [PATCH 109/180] docs(setup): document supports_tools opt-in for
 manual Ollama /v1 endpoints (#5835)

* docs(setup): document supports_tools opt-in for manual Ollama /v1 endpoints

Manually-added Ollama /v1 endpoints default to the conservative
fenced-block tool-calling path, and there's currently no UI control to
opt a specific endpoint into native tool calling (#5192). The
supports_tools PATCH flag already exists and works, it just wasn't
documented anywhere a user could find it without reading source.

Adds a short section next to the existing "Ollama with Docker" notes
explaining when to use it and the exact API call, framed as an
advanced/opt-in setting per the maintainer's stated preference against
a casual UI toggle (#3195/#3438).

* docs(setup): clarify supports_tools false semantics

 models through Odysseus/llama.cpp, so Windows users with an existing Ollama
 install usually only need to add the endpoint in Settings.
 
+**Tool calls not firing on a manually-added Ollama `/v1` endpoint.** By
+design, a local Ollama `/v1` endpoint defaults to the conservative
+text-based (fenced-block) tool-calling path rather than native structured
+tool calls, since some locally-served models mishandle native schemas (see
+#1567). This is correct for most local setups, but if you know your specific
+model reliably supports native tool calling (check `ollama show <model>` for
+`tools` under Capabilities), you can opt that endpoint in explicitly. There
+is currently no UI control for this on manually-added endpoints (see #5192);
+the flag can still be set directly against the existing API, from a browser
+console on an authenticated admin session:
+
+```js
+fetch('/api/model-endpoints/<endpoint-id>', {
+  method: 'PATCH',
+  credentials: 'same-origin',
+  headers: {'Content-Type': 'application/json'},
+  body: JSON.stringify({supports_tools: true})
+}).then(r => r.json()).then(console.log)
+```
+
+Find `<endpoint-id>` by inspecting the `/api/model-endpoints` response (or
+your browser's network tab while Settings loads the endpoint list). Send
+`supports_tools: false` to disable native structured tool calls and force the
+conservative fenced/text path, or `supports_tools: null` to return the endpoint
+to the Auto heuristic.
+
 **Useful checks.**

Subject: [PATCH 114/180] fix(cookbook): record real Windows pid for local
 serve so Stop kills the model (#5912)

* fix(cookbook): record real Windows pid for local serve so Stop kills the model

The Windows-local serve runner recorded Git Bash's `$$`, which is the
MSYS/Cygwin pid, not the Windows pid. Win32 tooling (taskkill,
Get-CimInstance ParentProcessId, Stop-Process) can't match an MSYS pid, so
the frontend Stop-Tree walk found nothing and the llama-server child survived
after Stop, leaving the model loaded and the GPU pinned.

Record the serving shell's true Win32 pid via `/proc/$$/winpid`, falling back
to the outer proc.pid already written from Python when the map is unavailable.

The existing pid-tracking test asserted the buggy `$$` literal at the source
level, so it passed while the feature was broken; update it to the winpid
behavior and add a focused regression test.

* fix(cookbook): make Windows serve pid handoff deterministic

From: Alexandre Teixeira <111787685+alteixeira20@users.noreply.github.com>

Subject: [PATCH 116/180] refactor(model-routing): centralize explicit
 foreground fallback policy (#6020)

* refactor(model-routing): centralize explicit foreground fallback policy

Make foreground fallback an explicit per-user, availability-only policy shared by streaming Chat, non-stream Chat, and Agent runs.

Preserve strict defaults, owner/model and credential boundaries, pinned Agent routes, and truthful per-round provenance/accounting. Carry provider-reported model identifiers through native streaming adapters, non-stream responses, and caches, and keep legacy default_model_fallbacks as tombstoned raw storage that generic settings APIs and agent tools cannot expose or mutate.

* fix(agent-loop): restore rebase-dropped qwen routing, workspace prompt, and temperature clamp

* fix(model-routing): thread selected endpoint identity, fix cost classification and fallback eligibility

* fix(chat): restore stream helpers and harden run stop lifecycle

* fix(model-routing): let numeric provider codes win over symbolic rate-limit statuses

* fix(agent-loop): apply qwen temperature and notes-tool clamps per fallback candidate

* fix(chat): honor queued stop across resend and reload canonical terminal on EOF

* fix(chat): track stop queue and cleanup ownership by per-send generation

* fix(agent-loop): preserve requested temperature for non-qwen fallback candidates

* fix(chat): reserve send ownership before any await and scope stop to the current send

* fix(chat): clear the previous run identity at send reservation

Subject: [PATCH 117/180] fix(scheduler): treat /api/email/unread-state as
 passive UI poll (#6009)

Background scheduled agent runs were aborted as "Stopped by user" when
the web UI was merely open, because the idle /api/email/unread-state
poll was counted as foreground activity while its sibling
/api/email/urgency-state was already excluded.

Fixes #5981

Subject: [PATCH 118/180] fix: stop status polling from cancelling running
 scheduled tasks (#5789)

* fix: stop polling GET /api/tasks/runs/recent from cancelling running tasks

Two paths caused the scheduler to interrupt a running background task
when the frontend Activity view polled for status:

1. GET /api/tasks/runs/recent was not in _PASSIVE_EXACT_PATHS, so
   _InteractiveActivityMiddleware treated it as a foreground request
   and called stop_background_tasks_for_foreground, cancelling any
   in-flight scheduled task. Add it to _PASSIVE_EXACT_PATHS alongside
   the other read-only polling endpoints.

2. The /api/activity/heartbeat handler called
   stop_background_tasks_for_foreground unconditionally, ignoring
   BACKGROUND_TASK_FOREGROUND_GATE=false. Wrap the call in a
   _gate_enabled() guard so the env var fully disables heartbeat-
   triggered cancellations.

Fixes #5782

Subject: [PATCH 119/180] fix(skills): harden skill import against DNS
 rebinding and SSRF TOCTOU (#5986)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(skill-importer): validate URL scheme and improve skills.sh handling

* fix(skill-importer): enhance DNS resolution and SSRF protection in fetch URL handling

* fix(url-safety): add allowed_dist parameter to check_outbound_url for flexible private blocking

* test(skill-importer): add comprehensive tests for URL parsing and outbound checks

* ensure newline at end of file in test_check_outbound_url_allows_public_ip

* fix(skill-importer): improve TLS certificate handling in _get_checked function

* fix(skill-importer): enhance _check_fetch_url to handle both hostnames and full URLs

* fix(skill-importer): enhance parse_skill_source to support skills.sh URLs in path and netloc

* fix(skill-importer): simplify skills.sh hostname check in parse_skill_source

* fix(skill-importer): enhance parse_skill_source to identify skills.sh URLs in path and handle localhost/IP addresses

* fix(skill-importer): enhance _resolve_and_check_url to validate all resolved IP addresses and prevent TOCTOU vulnerabilities

* fix(skill-importer): enhance parse_skill_source to support schemeless GitHub and skills.sh URLs

* fix(memory): resolve CodeQL URL sanitization warning and restore _check_fetch_url test alias

* fix(memory): pin skill fetch sockets without rewriting URLs

* fix(memory): reject unsupported skill wrapper hosts

* refactor(url-safety): remove unused importer exception

* test(memory): keep redirect regression hermetic

* test(dns-rebinding): add test for _PinnedTransport to ensure connection to pinned IP

* fix(skill-importer): enhance skills.sh support to extract GitHub links from page content

* fix(skill-importer): improve URL scheme validation for GitHub and skills.sh links

* fix(skills): reject unusable skill URLs instead of guessing

Resolving a skills.sh link by scraping the first github.com URL out of
the page body cannot work. Skill pages only ever link the repository
root, never the skill's subdirectory, so every skill in a repo resolved
to the same bundle: importing skills.sh/anthropics/skills/pdf walked the
whole monorepo, saturated the 64-file cap, and installed algorithmic-art
behind an ok:true response. Restore the redirect-target unwrap and fail
with a message that says what to do instead.

Also report the real reason a URL is rejected. The scheme check keyed off
"://" appearing anywhere in the string, so a supplied-but-unusable URL
came back as "URL is required", and a schemeless URL carrying "://" in
its query was reported as an unsupported scheme. Key off the parsed
scheme and let opaque schemes (mailto:, javascript:) and a schemeless
host:port fall through to the host check.

* test(skills): tighten the real-socket pinning regression

The handler swallowed its own exceptions, so a failure inside it
surfaced as a confusing assertion on the captured client address.
Record the exception and assert on it, run the thread as a daemon, and
close the listening socket from the test so a hang cannot outlive the
run. Also drop the duplicate ipaddress import and the missing newline.

* fix(skills): require exact GitHub skill URLs

* test(skills): read complete pinned request headers

Subject: [PATCH 120/180] docs(setup): document the HTTP/2 reverse-proxy setup
 (#6046)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* docs(setup): document the HTTP/2 reverse-proxy setup

The "private or proxied deployments" section named Caddy, nginx and Traefik
but gave no runnable config, and never mentioned the main reason to bother:
the frontend is unbundled ES modules, so a page load is a few hundred small
same-origin requests. Over HTTP/1.1 the 6-connection cap serialises those
into dozens of round trips, which is invisible on localhost and dominates
load time over a LAN or VPN.

Adds a five-step setup you can paste: a Caddyfile for each of the three ways
people reach these boxes (public domain, Tailscale, own certificate), how to
run the proxy in the foreground and then as a service, the .env keys that
have to follow the origin, and a curl one-liner to confirm HTTP/2 actually
negotiated.

Also covers what bites when moving an existing install behind TLS:
SECURE_COOKIES applying regardless of the scheme the request arrived on,
OAUTH_REDIRECT_BASE_URL still defaulting to localhost because the MCP
redirect is registered up front rather than derived per request, and HSTS
being host-wide and port-agnostic. Notes that a custom HTTPS port does not
stop Caddy binding port 80 for the redirect, which is the failure I hit
first.

Docs only — no code change is needed to run behind HTTP/2 today.

* docs(setup): clarify HTTP/2 and origin migration

 Cloudflare Access, Tailscale, Caddy, nginx, and Traefik can all fit this pattern; none are required by Odysseus. If your access layer reaches Odysseus on the same host, proxy to `http://127.0.0.1:7000` and keep `AUTH_ENABLED=true`, `LOCALHOST_BYPASS=false`, and `SECURE_COOKIES=true`.
 `ALLOWED_ORIGINS` lists exact permitted origins for cross-origin browser/API clients; ordinary same-origin reverse-proxy access usually does not need a special CORS entry.
 
+#### Faster over the network: HTTP/2
+
+The frontend is raw ES modules with no bundler, so a page load is a few hundred
+small same-origin requests. Over HTTP/1.1 browsers typically allow only a small
+number of concurrent connections per host (commonly around six), so many of
+those requests are serialized across multiple round trips. On localhost that
+costs almost nothing. Over a LAN, VPN, or remote link it can become a major
+part of load time, especially as latency increases.
+
+HTTP/2 multiplexes them onto one connection and the serialisation disappears.
+Odysseus needs no changes for this — uvicorn keeps speaking HTTP/1.1 on
+loopback and the proxy speaks HTTP/2 to the browser. Mainstream browsers
+negotiate HTTP/2 for normal web pages over TLS; they do not use the cleartext
+h2c mode here, so browser-facing HTTP/2 requires a certificate. The
+`--ssl-certfile` route in *HTTPS + LAN/Tailscale exposure* above gives you
+HTTPS but not HTTP/2 — uvicorn does not speak it.
+
+**1. Install Caddy.** See the [install docs](https://caddyserver.com/docs/install)
+for your platform; on macOS, `brew install caddy`.
+
+**2. Write a `Caddyfile`.** Pick the block that matches how you reach the
+machine. Replace `7000` if Odysseus listens elsewhere — the macOS start script
+uses `7860`.
+
+Public domain, Caddy obtains and renews the certificate itself:
+
+```
+odysseus.example.com {
+	reverse_proxy 127.0.0.1:7000
+}
+```
+
+Tailscale, no public DNS needed — `tailscale cert` issues a browser-trusted
+certificate for a tailnet name and writes `<domain>.crt` and `<domain>.key`:
+
+```bash
+tailscale cert myhost.tailnet-name.ts.net
+```
+
+```
+myhost.tailnet-name.ts.net {
+	tls /path/to/myhost.tailnet-name.ts.net.crt /path/to/myhost.tailnet-name.ts.net.key
+	reverse_proxy 127.0.0.1:7000
+}
+```
+
+LAN with your own certificate — same shape, your own files:
+
+```
+odysseus.lan {
+	tls /path/to/cert.pem /path/to/key.pem
+	reverse_proxy 127.0.0.1:7000
+}
+```
+
+Give `tls` absolute paths: a service starts in a working directory you did not
+choose. If port 443 is already taken, append a port to the site address
+(`odysseus.example.com:8443`) and use it in the URL. That alone does not free
+port 80 — Caddy still binds it for the HTTP-to-HTTPS redirect, and fails to
+start with `listen tcp :80: bind: address already in use` if something else
+holds it. Turn the redirect off with a global block at the top of the file:
+
+```
+{
+	auto_https disable_redirects
+}
+```
+
+**3. Run it in the foreground first:**
+
+```bash
+caddy run --config ./Caddyfile
+```
+
+Once that works, run it as a service:
+
+```bash
+brew services start caddy          # macOS — reads $(brew --prefix)/etc/Caddyfile, not ./Caddyfile
+sudo systemctl enable --now caddy  # Linux, if your package installed the unit
+```
+
+Odysseus's own service is unchanged; the proxy runs alongside it. Under Docker,
+run the proxy as another container, or on the host pointing at the published
+port.
+
+**4. Point Odysseus at the new origin** in `.env`, then restart it:
+
+```bash
+SECURE_COOKIES=true
+# only if you use remote MCP servers with OAuth:
+OAUTH_REDIRECT_BASE_URL=https://odysseus.example.com
+```
+
+Gmail OAuth needs nothing here when the proxy runs on the same host: the
+redirect URI is built from the incoming request, and uvicorn rewrites the
+scheme from `X-Forwarded-Proto` for proxies it trusts — by default only
+`127.0.0.1`. A proxy in a separate container or on another machine is not
+trusted, so pin the URI there:
+
+```bash
+GOOGLE_OAUTH_REDIRECT_URI=https://odysseus.example.com/api/email/oauth/google/callback
+```
+
+(uvicorn's own `FORWARDED_ALLOW_IPS` widens that trust, but it has to be in the
+environment uvicorn starts with — `.env` is read by the app afterwards, too
+late for it to take effect.)
+
+**5. Confirm HTTP/2 is really on:**
+
+```bash
+curl -s -o /dev/null -w '%{http_version}\n' https://odysseus.example.com/
+# 2
+```
+
+The status code is not the thing to check here — a logged-out request redirects
+to the login page, so `curl -I` shows `HTTP/2 302`, and the `HTTP/2` prefix is
+the part that matters. The browser reports the same in the Network panel's
+Protocol column (`h2`); in Chrome and Firefox that column is hidden until you
+enable it by right-clicking the column headers.
+
+Three things bite when moving an existing install behind TLS:
+
+- Set `SECURE_COOKIES=true` **at the same time** you stop serving plain HTTP,
+  not before. The flag is applied to every login regardless of the scheme the
+  request arrived on, so while an HTTP entrypoint is still reachable the
+  browser will reject the `Secure` cookie there and login will appear to loop.
+- `OAUTH_REDIRECT_BASE_URL` defaults to `http://localhost:7000`. Unlike the
+  Gmail redirect URI it cannot be derived from a request — it is registered
+  with each MCP authorization server up front — so set it to the external
+  origin if you use remote MCP servers over OAuth.
+- Odysseus sends `Strict-Transport-Security` once it sees `X-Forwarded-Proto:
+  https`. HSTS applies to the whole hostname and ignores the port, so any other
+  plain-HTTP service on that same hostname becomes unreachable in browsers that
+  have visited Odysseus. Give Odysseus its own hostname, or strip the header at
+  the proxy (`header_down -Strict-Transport-Security` in Caddy).
+
+Server-sent events are not buffered by this configuration, so chat streaming
+arrives token by token; add `flush_interval -1` inside the `reverse_proxy`
+block if you want that pinned explicitly. nginx needs `proxy_buffering off;`
+for the same reason.
+
+Changing the external origin also affects state scoped to it. Service workers
+and their caches are origin-scoped, so moving to a different origin starts with
+a cold load. Cookies follow their own domain/path/security rules rather than
+being port-scoped: changing the hostname normally requires a new login, while
+changing only the scheme or port does not by itself guarantee that existing
+cookies disappear.

Subject: [PATCH 137/180] fix(personal): run directory indexing off the event
 loop (#5634)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(personal): run directory indexing off the event loop (#5558)

POST /api/personal/add_directory called rag.index_personal_documents
inline from an async handler, so the whole indexing job (os.walk, file
reads, per-chunk embedding, Chroma inserts) ran on the event loop and
every other request queued behind it. Indexing a real directory froze
the UI and API for 25+ minutes with no sign of life.

Move the blocking section into the threadpool via run_in_threadpool.
personal_docs_manager.add_directory stays inside it because its
refresh_index() re-extracts text across tracked directories, which is
also blocking work. A module-level lock serializes index jobs so the
threadpool move does not introduce parallel jobs racing
PersonalDocsManager's unsynchronized list mutations and file writes;
they previously serialized on the blocked loop, so one-at-a-time is
behavior parity.

* fix(personal): serialize add/remove/reload on an async job lock

The #5558 fix took the job lock INSIDE the threadpool worker and only on the
add path, so (1) remove_directory and /reload mutated PersonalDocsManager's
unsynchronized list/index concurrently with an in-flight add — the inconsistent
state the PR claimed to prevent — and (2) a queued add blocked on the lock while
holding an AnyIO threadpool token, starving the shared pool.

Move the lock to an asyncio.Lock acquired in the async handler BEFORE offloading,
and route add, remove and reload through it. A waiting request now parks on the
event loop instead of pinning a worker, and all three mutators are serialized so
the 'add/remove are serialized and cannot leave inconsistent state' guarantee
holds. remove and reload also run their blocking work off the event loop. The
lock is per-router so each app binds it to its own loop; single-process scope.

Tests: add-vs-remove and add-vs-reload serialization regressions (async via
ASGITransport, since asyncio.Lock deadlocks starlette TestClient's portal); the
existing add-vs-add test converted to the same driver.

* fix(personal): route upload and delete through the index job lock

/api/personal/upload and DELETE /api/personal/file mutated the same
vector and tracking state add/remove/reload serialize on, outside
_index_job_lock and inline on the event loop.

Both now stage async work on the loop, then run the complete transition
(vector writes, disk change, personal_docs_manager update) in one
offloaded critical section under the shared lock, acquired before the
offload so queued requests park on the loop rather than pinning a
threadpool worker.

Adds add-vs-upload and add-vs-file ordering regressions.

* fix(personal): bound multi-file upload memory

+(os.walk + file reads + per-chunk embedding + Chroma inserts) inline, so
+FastAPI ran the whole job on the event loop and every other request queued

Subject: [PATCH 139/180] fix(chat): centre the agent-thread terminating dot on
 the rail (#6059)

The timeline's terminating dot used a single left offset (-17px) at both
breakpoints, but the thread's padding-left differs (22px desktop, 18px
mobile) and the step dots already carry a per-breakpoint offset. The 6px
dot therefore landed 2px right of the 2px rail on desktop and 2px left of
it on mobile, which is the visible kink under an expanded last step.

Derive each offset from the rail's centre instead: the rail sits at
left:5px and is 2px wide, so the dot's left edge belongs at 3px, giving
3px - padding-left per breakpoint.

+"""Agent-thread timeline dots must stay centred on the vertical rail.
+
+Source-text assertions here are the narrow exception allowed by
+TESTING_STANDARD.md: the invariant is pure CSS geometry, and driving it at
+runtime would need a real layout engine, which the suite has no runner for.
+The test parses the declared pixel values and recomputes the centres rather
+than pinning literals, so retuning the spacing keeps it green — but moving a
+breakpoint's padding without moving both dot offsets turns it red.
+
+The thread's padding is restated once per breakpoint, and each breakpoint's

Subject: [PATCH 144/180] fix(docker): migrate retained SearXNG settings
 (#6055)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(docker): migrate retained SearXNG settings

Retained nonempty SearXNG settings can miss defaults required by newer pinned images while bypassing the entrypoint's narrow regeneration checks.

Add an atomic PyYAML-aware migration to all Compose variants. Preserve existing inheritance choices, custom content, secrets, ownership, and mode while inserting only the missing top-level default-inheritance key.

Validated with 39 focused and adjacent tests, compile checks, and fresh and retained pinned-image HTTP 200 gates. Full repository CI remains for the PR.

* fix(docker): chmod the settings temp file before chowning it

The Compose cap set is `cap_drop: ALL` plus CHOWN/SETGID/SETUID/DAC_OVERRIDE
and carries no FOWNER, and searxng's own entrypoint chowns /etc/searxng to
searxng:searxng, so every retained settings file belongs to that user by the
second boot. Chowning the temporary file first left root unable to chmod it,
so the migration exited 1 and `set -eu` killed the container before
`exec /usr/local/searxng/entrypoint.sh` — SearXNG never started and odysseus
blocked on its healthcheck.

Swap the two calls so the chmod lands while the temporary file is still
root-owned, and cover the ordering with a test that refuses the chmod once
the chown has happened, the way the kernel does.

* fix(docker): let searxng boot when the settings migration fails

The migration runs under `set -eu`, so any settings file it cannot parse or
rewrite took the container down instead of merely going unmigrated. A symlinked
/etc/searxng/settings.yml is enough: the migration refuses a non-regular file
and searxng, which reads through the symlink perfectly well, never got to start.

Guard the call with `|| true` in all three Compose variants. The failure still
prints its reason on stderr, and searxng is left to report anything genuinely
wrong with the file.

Subject: [PATCH 145/180] fix(mcp): stop assuming http://localhost:7000 for the
 OAuth callback (#6032)

* fix(mcp): stop assuming http://localhost:7000 for the OAuth callback

The MCP OAuth callback origin is wrong on any install not reached at
http://localhost:7000, and on Docker it cannot be corrected at all.
Three sites, one assumption:

- The redirect base fell back to a fixed port 7000. The app binds APP_PORT
  natively (app.py, launcher.py) and the macOS launcher defaults to 7860,
  where 7000 is AirPlay Receiver, so the callback lands on another service
  entirely. The fallback now follows APP_PORT. The hostname stays localhost
  rather than internal_api_base()'s 127.0.0.1: this URI is registered with
  the authorization server, so changing the host would invalidate the
  registrations that already exist.

- The paste-back form hardcoded an http:// action. Serving the page over
  HTTPS, Chrome raises its insecure-form interstitial, and overriding that
  posts plain HTTP at a TLS port, which fails too. Either way the
  authorization code never reaches Odysseus. The action now carries the
  scheme the request arrived on.

- OAUTH_REDIRECT_BASE_URL is the only fix available to a Docker install,
  because the container listens on 7000 and cannot see the host port map,
  but compose never forwarded it and nothing documented it. Both fixed.

* fix(mcp): make the paste-back form action relative and export APP_PORT

Answers the review on #6032. Three of the fixes did not survive contact with
the deployments they targeted.

- The form action derived its scheme from request.url.scheme. uvicorn only
  honours X-Forwarded-Proto from a peer inside --forwarded-allow-ips, which
  defaults to 127.0.0.1; the Dockerfile CMD sets no override, so a proxy
  arriving over the Docker bridge is untrusted and the scheme stays http.
  That is mixed content on exactly the HTTPS installs paste-back exists for.
  A relative action is resolved by the browser against the origin the page
  came from, which is right under every proxy setup, and it drops the Host
  header from the page entirely.

- The APP_PORT fallback never fired for the shipped launchers. start-macos.sh,
  the generated .app launcher and launch-windows.ps1 all pass --port to
  uvicorn without putting the value in the environment, so the motivating
  case, macOS on 7860, still registered localhost:7000. Each now exports it.
  internal_api_base() and companion pairing read APP_PORT too and were wrong
  in the same way.

- .env.example pointed Google MCP servers at OAUTH_REDIRECT_BASE_URL.
  add_server writes Desktop App credentials, and Google only accepts loopback
  redirects for that client type, so a public origin comes back as
  redirect_uri_mismatch. The variable is for the DCR flow; Google stays on the
  loopback default and finishes remotely through paste-back.

The Host header is no longer reflected into the page, so the escaping
regression test asserts its absence instead of its escaping.

Subject: [PATCH 147/180] fix(tasks): scope action_tidy_research broken-file
 sweep to admins (#6069)

action_tidy_research took an `owner` argument and never used it. Any user's
scheduled tidy task swept data/deep_research globally, unlinking every empty
or unparseable file regardless of who owned it.

A broken file has no readable owner stamp, so it cannot be matched against
`owner` the way _find_owned_research_path does, which is why the HTTP path and
manage_research already treat parse failure as not-owned. Clearing one is a
privileged act rather than an ownership one, so gate it on the canonical
owner_is_admin_or_single_user helper: admins and the single-user operator keep
the janitor, a regular user does not, and neither does the pre-setup window
before an admin exists.

Returns before the directory glob rather than filtering inside the loop, so a
denied run reports why instead of reporting "none broken" over files it never
inspected. That reason string surfaces in Activity as a skipped row.

Subject: [PATCH 148/180] fix(ci): match the screenshot checkbox by wording,
 not emphasis (#6073)

The PR-description check folded the template's asterisks into the pattern,
so a ticked box written without them read as unchecked while rendering
identically on the PR page. `ready for review` was silently withheld and
the bot reported missing visual evidence even with screenshots attached,
with no way to tell from the rendered PR what was wrong.

The two attestations directly above it already anchor on the wording
alone. This one now does the same, accepting `**bold**`, `*italic*`,
`__underscores__` and plain text.

Fixes #6071

Subject: [PATCH 149/180] refactor(static): load the image editor on first use
 (#6074)

galleryEditor.js and its js/editor/ graph are 54 modules / 576 KB, and
gallery.js imported them statically. Every page load paid for the whole
image editor even though most sessions never open the Edit tab: 54 of the
173 JS files on a cold load, and 576 KB of the decoded JS, were for a
panel that was never displayed.

Add a small panel-loader registry (static/js/panels.js) that imports a
panel's module on first use and memoises the promise, so a double-click
cannot start two loads and a failed load can still be retried. Convert
the image editor to it, and route the two existing dynamic imports in
chat.js and chatRenderer.js through the same entry so all three call
sites share one module instance instead of two.

closeEditor() and isEditorOpen() stay synchronous: if the module was
never loaded there is no edit session to close and none can be open.

The service worker keeps precaching the editor, in a separate
PANEL_PRECACHE list, so the panel stays available offline even though
index.html no longer loads it. The two lists now serve different
purposes and the header comment says so.

+r"""Behaviour of the panel-loader registry in `static/js/panels.js`.
+
+The registry is what keeps a lazily-loaded panel honest: it must import a
+panel's module exactly once no matter how many times the user clicks, it must
+fail loudly on a name nobody registered (rather than handing back `undefined`
+and blowing up somewhere unrelated), and it must not memoise a *failed* load —
+otherwise a panel that failed to load once while offline would stay broken for
+the rest of the session.
+
+`createPanelLoader` is exercised with stub thunks so these tests need no DOM and
+no real panel module graph. The production `loadPanel` is the same function
+applied to the real registry, checked here only for its registered names.

Subject: [PATCH 150/180] perf(frontend): share one cached fetch for
 /api/auth/settings and /api/tools (#5997)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* perf(frontend): share one cached fetch for settings and tools

/api/auth/settings was fetched independently by eight modules and /api/tools by
three on a single load — 4 and 3 requests measured — and any two of those
callers could observe a different snapshot of the same object. chatRenderer.js
is imported under three different ?v= query strings, so it is three separate
module instances each issuing its own /api/tools request.

appConfig.js holds one promise per endpoint, so concurrent and later callers
share it. Every writer invalidates: the settings panel routes its 16 saves
through a single helper, and the admin tools save drops both snapshots because
that route persists disabled_tools into the same settings store. A rejected
fetch clears its slot rather than being memoised, so one blip at boot cannot
leave keybinds, TTS and the search provider on defaults for the session.

The settings panel keeps reading directly: it is the writer and edits what it
reads, so it must see authoritative state.

Cold load, Resource Timing: /api/auth/settings 4 -> 1, /api/tools 3 -> 1, and
0 settings requests on the first load after a login, because the cache now
consumes the sessionStorage prefetch that login.html writes.

Fixes #5996

* fix(admin): refetch tool state when the Agent Tools panel opens

The shared cache made Admin > Tools render the boot snapshot on every
reopen. Its save posts the whole disabled list rebuilt from the checkboxes,
so a tool disabled out of band (the manage_settings tool, another tab) came
back enabled on the next unrelated toggle. Reproduced against the running
app: with api_call disabled by a separate client, toggling app_api off
posted ['app_api'] and silently re-enabled api_call.

The panel now drops the shared entry before reading it, which restores what
dev does today and keeps the startup read that chatRenderer.js shares. Cold
load is still 1 request each for /api/auth/settings and /api/tools, and the
panel costs the same 2 requests per open as dev.

* fix(static): preserve concurrent tool setting changes

+"""Pin the shared config cache in static/js/appConfig.js.
+
+Background: /api/auth/settings was fetched independently by six modules and
+/api/tools by three (chatRenderer.js is imported under three different ?v=
+query strings, so it is three separate module instances) — 4 and 3 requests on
+one cold load. Beyond the redundant work, each caller could observe a different
+snapshot of the same object. appConfig.js gives them one promise each.
+
+The two properties that matter are opposites, so both are tested here:
+concurrent and later callers must NOT refetch, and a caller after a write MUST
+see the new value — which only holds if every writer invalidates. The last test
+is a source scan that checks exactly that, since a forgotten invalidation
+serves a stale settings object for the rest of the session, which is worse than
+the duplicate fetches this replaces.
+
+Driven through `node --input-type=module` so the real module runs, same idiom as
+test_esc_menu_stack_js.py. The module source is inlined rather than imported by
+path because the repo has no `"type": "module"` in package.json; appConfig.js
+has no imports of its own, so inlining is exact. `fetch` and `sessionStorage`
+are stubbed, so nothing here touches the network or depends on timing.

Subject: [PATCH 151/180] perf(static): vendor KaTeX and Mermaid, and load them
 on first use (#5994)

* fix(static): vendor KaTeX and Mermaid instead of loading them from a CDN

index.html pulled katex.min.{js,css} and mermaid.min.js from cdn.jsdelivr.net on
every page load. For self-hosted software that is three problems at once: an
air-gapped or offline install renders no math and no diagrams at all, every
session announces its IP, User-Agent and Referer to a third party, and the "runs
on your own hardware" promise quietly isn't true.

static/lib/ already vendors highlight.js, docx, xlsx, mammoth, html2pdf and
qrcode, so the CDN usage was an inconsistency rather than a policy. Vendoring
also pins Mermaid, which was floating on the `11` tag, to 11.16.1.

Behaviour is unchanged: both libraries still load eagerly from <head>, just from
this machine.

- KaTeX goes in its own directory because its stylesheet resolves fonts with a
  relative url(fonts/...), so the vendored CSS needs no rewrite. Only the .woff2
  variants ship, matching static/fonts/, since a browser that supports woff2
  never requests the .woff/.ttf alternatives the stylesheet also lists.
- The service worker precaches KaTeX and its fonts so offline math is typeset
  rather than falling back to system glyphs, and CACHE_NAME is bumped. Mermaid
  is left to the existing cache-first rule: at 3.5 MB, precaching it would mean
  re-downloading it on every cache bump for a library most sessions never touch.
- Licence texts travel with the bundles in licenses/, following the convention
  the repo already uses for OpenDyslexic and DeepResearch.
- .gitattributes turns the whitespace check off for static/lib/ so `git diff
  --check` passes without stripping bytes from the published npm artifacts,
  which would desync them from upstream.

* perf(markdown): load KaTeX and Mermaid on first use, not on every page load

Both libraries loaded eagerly from <head>, costing every session ~985 KB on the
wire (929 KB of that Mermaid) even though most chats contain neither a formula
nor a diagram. Measured on a cold profile via the Resource Timing API: JS bytes
per page load drop from 3,102,141 to 2,098,634, a saving of 1,003,507 bytes, and
third-party requests per load go from 3 to 0.

markdown.js now fetches each library the first time one is actually needed:

- renderMermaid() checks for an unprocessed mermaid fence before touching the
  network, and re-queries the DOM after the load so a diagram replaced mid-stream
  still renders.
- mdToHtml() is synchronous, so when KaTeX is not in yet it banks the math source
  in an inert placeholder and schedules a flush that loads the library and swaps
  the placeholders in. Once KaTeX is loaded it typesets inline exactly as before,
  so callers that never call a render helper still get their math.

Both loaders memoise the promise rather than the module, so concurrent callers
share one fetch and a double trigger cannot start two loads; a failed load clears
the memo so the next formula retries instead of being poisoned for the session.
The flush is scheduled with setTimeout rather than requestAnimationFrame, which
is throttled to a stop in a background tab and never fires at all in a headless
browser, so math would have sat as plain source text until the tab was focused.

If neither library ever loads, math degrades to readable source text and diagrams
to their fence contents, rather than to nothing.

* fix(markdown): unescape &amp; last so math entities survive intact

The math pass unescaped &amp; before &lt; and &gt;. mdToHtml escapes the source
first, so a literal "&lt;" typed inside a formula arrives here as "&amp;lt;",
turns back into "&lt;" on the ampersand pass, and is then eaten by the very next
one. Typing $a &lt; b$ rendered as "a < b" instead of the literal text.

The code-block pass in the same function already unescapes &amp; last; only the
math paths were the outlier, in all four of the copies this branch consolidated
into pushMath(). Reordering to match makes them consistent and clears the
js/double-escaping alert CodeQL raised on this PR.

Math containing a genuinely typed "<" is unaffected, which is why this went
unnoticed for so long. Covered by a regression test asserting both cases.

* fix(markdown): decode entity-spelled math in one pass

mdToHtml escapes the source before the math pass, so a typed "<" reaches
the delimiters as "&lt;" and a typed "&lt;" reaches them as "&amp;lt;".
KaTeX has no entity syntax and reads the leftover "&" as an alignment
marker, so "$a &lt; b$" rendered as a red .katex-error instead of a
formula, on both the inline and the deferred path.

Chained replaces cannot fix it in either order: unescaping "&amp;" first
lets the next pass eat the "&lt;" it just wrote, and unescaping it last
leaves the entity spelling for KaTeX to choke on. One alternation,
longest form first, decodes every spelling and never rescans its own
output.

The tests now drive the vendored KaTeX build rather than a renderer that
echoes its input, which is why the old assertion looked correct.

* fix(document): typeset deferred math before the PDF export

exportAsPdf() renders the document into a detached container and hands
it straight to html2pdf. On a page where KaTeX has not loaded yet,
mdToHtml() returns pending placeholders and schedules a flush scoped to
document, which never reaches a node that was never attached, so the
PDF printed raw formula source.

Render the container's own math first. renderMath() returns immediately
without fetching anything when there is nothing pending, so a document
with no formulas still exports without pulling KaTeX.

Subject: [PATCH 152/180] fix(auth): derive the session cookie Secure flag from
 the request scheme (#6048)

* fix(auth): derive the session cookie Secure flag from the request scheme

SECURE_COOKIES only marked the login cookie Secure when it was explicitly
set to true, so an HTTPS login on an install that never set it handed out a
session cookie the browser is happy to send back in cleartext.

Unset now derives the flag from the request: the connection scheme, which
uvicorn's proxy-headers middleware rewrites for the proxies it trusts, or
X-Forwarded-Proto for a terminator that is not on a trusted address. That
is the same test core/middleware.py already applies before sending HSTS, so
the two stop disagreeing about whether a request arrived over TLS. An
explicit true still forces the flag on and an explicit false turns it off
for an install still answering on both HTTP and HTTPS. Strictly more Secure
flags than before and never fewer.

Empty counts as unset, because docker-compose pinned SECURE_COOKIES=false
for every container; the compose files now pass the variable through
unset, the way FASTEMBED_CACHE_PATH already does.

The helper and its decision order come from #3799, which was closed for
being too large to review and whose six replacement PRs dropped this fix.

Part of #3803.

* docs(setup): flag the leftover SECURE_COOKIES=false on upgrades

The old default was false, so an install set up before scheme derivation
can still carry an explicit SECURE_COOKIES=false in its own .env. That
value stays authoritative, so HTTPS logins keep getting a non-Secure
session cookie even after the tracked compose defaults are updated by a
pull. Say so where people look: the security notes and the variable's
own comment in .env.example.

* docs(setup): align TLS guidance with scheme-derived cookies

Subject: [PATCH 156/180] fix: discover sessions from persisted messages
 (#5938)

* fix(session): discover sessions from persisted messages

Use indexed chat-row existence instead of stale derived message_count metadata during startup discovery, then repair the bounded in-memory counts so lazy hydration remains correct. Keep truly empty sessions excluded and cover stale-low and stale-high counts with real SQLite.

* test(session): isolate discovery database

* test(session): use manager database metadata

+| `kokoro`, `soundfile` | Local Kokoro-82M text-to-speech on a CUDA GPU. The pinned Kokoro release supports Odysseus installs on Python 3.11-3.12; these packages are intentionally skipped on Python 3.13+ (including the Python 3.14 container image). |

 | `PyMuPDF` | PDF page rendering in the side viewer panel and form-filling. (Note: AGPL-3.0) |
 | `markitdown` | Office/EPUB document text extraction (converts .docx/.xlsx/.pptx/.xls/.epub to Markdown). |
 
+Install the optional set only when you need these features:
+
+```bash
+pip install -r requirements-optional.txt
+```
+
+The default Docker image currently uses Python 3.14, while Kokoro 0.9.4 declares Python `>=3.10,<3.13`. Odysseus itself continues to support Python 3.11+, but this pinned optional local-TTS feature requires a native Python 3.11 or 3.12 environment. Kokoro declares `torch`, but the local provider only activates when that torch build has CUDA and a GPU is visible; install the CUDA build appropriate for your host. Browser and configured endpoint TTS remain available on Python 3.13+ and in the container image.

 ### Faster, reproducible installs with uv (optional)
 [uv](https://docs.astral.sh/uv/) works as a drop-in replacement for the
 venv + pip steps in the native install guides, no project changes are needed but this change results in faster installs along with a lockfile for reproducible environments. After [installing `uv`](https://docs.astral.sh/uv/getting-started/installation/), use:

Subject: [PATCH 161/180] refactor(routes): move task domain into routes/task/
 subpackage

Slice 2p of the route-domain reorganization (#4082/#4071). Moves
task_routes.py (1181 lines) into routes/task/, leaving a backward-compat
sys.modules shim. Pure file reorganization, no behavior change.

The shim uses sys.modules replacement so the `import ... as task_routes` +
`monkeypatch.setattr(task_routes, "SessionLocal", ...)` /
`"get_current_user"` pattern and the `task_routes.__file__` reads in
test_auth_regressions.py all reach the canonical module.

Four source-introspection test sites repointed:
- test_aux_llm_owner_scope.py
- test_model_helper_owner_scope.py
- test_internal_api_base.py
- test_webhook_trigger_auth_exempt.py

Adds tests/test_task_routes_shim.py to pin the sys.modules shim contract.

Verified: compileall clean; full suite 5040 passed, 3 skipped.

Subject: [PATCH 165/180] fix(time): prefer IANA timezone name over offset
 (#6122)

* fix(time): prefer IANA timezone name over offset

When both headers are present, resolve x-tz-name with ZoneInfo and ignore
a conflicting numeric offset. The prompt label uses the resolved zone so
name and UTC offset cannot disagree.

Related: #6111

* test(calendar): cover IANA timezone precedence

Subject: [PATCH 166/180] fix(agent): allow remaining actions for an approved
 task (#6113)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(agent): allow remaining actions for an approved task

* fix(agent): make approval continuation control-only

* fix(ci): preserve approval taint and cache-buster contract

* fix(ui): keep tool approvals in current chat

* fix(ui): route tool approvals through chat submit

* test(ui): pin approval submit routing

* fix(agent): complete approval denial flow

* fix(ui): avoid duplicate ask-user close icon

* fix(agent): retain approved tool in continuation set

* revert(ui): keep PR 6113 scoped to approval continuation

* fix(agent): add task and chat approval scopes

* fix(ui): prevent duplicate ask-user close icon

* feat(ui): add ask-user option shortcuts

* fix(compare): route ask-user choices per pane

* fix(agent): keep skill-test approvals to a single action

The chat card now reuses the wire value `approve` to mean chat-session
scope, and `consume()` returned `allow_remaining_actions=True` for it
unconditionally. The skill-test approval route was never updated: it still
sends `approve` meaning "once", and its button still reads "Allow once",
but the grant it got back set `approval_gate_bypassed` for the rest of the
resumed run. That surface wraps the skill body and every transcript byte
as untrusted context, so it is the last place where one click should
ungate everything that follows.

Give `consume()` an explicit `allow_continuation` flag. Callers that own a
resumable chat keep the scope the user picked; callers that do not — the
skill tester, unattended audits — get SINGLE_ACTION and the gate re-arms
behind the sealed action, which is what their label promises.

* fix(ui): cache-bust every module the approval click depends on

chatStream.js, compare/index.js and compare/stream.js all changed
behaviour but kept their old `?v=`, while chat.js and chatRenderer.js were
bumped. A returning browser therefore serves the new chat.js — which now
deliberately leaves the composer empty and clicks the send button — next to
the cached chatStream.js that has no interceptor. With an empty composer
that button sits at `data-mode="newchat"`, so the click opens a new chat
and the approval is dropped.

Bump the three, and version compare/stream.js's chatRenderer import to
match everyone else's so the ask_user keydown listener binds to one module
instance instead of two.

* fix(ui): keep the digit shortcuts off tool approval cards

With an approval card on screen and focus anywhere outside an input, a bare
`1` fired `approve_task` — the widest of the three grants — with no
modifier and no confirmation. That card is the one control whose entire
purpose is deliberate consent after untrusted context influenced the run,
and Deny sits at 3.

Label the card with its kind and skip the shortcut for approvals. Ordinary
ask_user questions keep 1-3.

* fix(compare): restore a pane's ask_user card instead of dropping the choice

renderAskUserCard removes the card as soon as onSubmit accepts, but the
resume loop gave up silently after 10s if the originating stream still owned
the pane. The user saw the click land, the card vanish, and nothing happen,
with no way to get it back.

Re-render the card on that deadline and say why. The reroll case still
returns without sending — that choice belongs to a stream that no longer
exists.

* refactor(chat): drop the unreachable deny branch

`if decision != "deny"` is always true — the deny path returns a
StreamingResponse a few lines above. It reads as if deny still falls
through to the toggle restore.

Subject: [PATCH 168/180] fix(agent): drop the empty assistant turn from an
 approved-action replay (#6124)

The approved-action replay appends the sealed tool result with no assistant
prose for that round, which produced an assistant message with content "".
Anthropic's Messages API rejects a non-final assistant message with empty
content, so a resumed turn after a tool approval failed before the model saw
the result. A turn carrying neither prose nor reasoning has nothing to say to
any provider, so it is no longer appended. A round with prose, and a
reasoning-only round that DeepSeek thinking mode needs, both still append.

Subject: [PATCH 169/180] Merge commit from fork

scripts/mlx_image_server.py resolved the model per request
(`req.model or _args.model`) on both /v1/images/generations and
/v1/images/edits, so the caller chose which model was served.

`_is_hidream()` is a substring test and `_snapshot_path()` accepts either a
local directory or a Hugging Face repo id, so a caller-supplied string
selected the HiDream branch and then supplied the directory it runs
`scripts/hidream_o1/generate_hidream_o1_mlx.py` from, under sys.executable.
The server has no auth, and the Cookbook binds it to 0.0.0.0 whenever it is
serving to a remote host, so one POST executed attacker code on the serving
host.

Both paths now use `_args.model`. The request field is still accepted for
OpenAI wire compatibility and ignored, matching scripts/diffusion_server.py,
and Odysseus already sends the served model's own id, so this is a no-op for
legitimate callers. /v1/images/harmonize already pinned.

Regression tests cover both endpoints, the local-directory and
Hugging-Face-repo halves, and that a server actually launched with a HiDream
model still serves it. Three of the four fail on the unfixed code.

Keep dev version metadata aligned with the current hotfix release while the rolling branch continues toward 1.1.0.

Evidence: the canonical APP_VERSION imports as 1.0.3 and the diff check is clean. This commit changes version metadata only; it does not tag or publish a release.

From 7026cf40b5f96f166f6b76e4236527d7dce243b1 Mon Sep 17 00:00:00 2001
From: RaresKeY <158580472+RaresKeY@users.noreply.github.com>
Date: Tue, 25 Aug 2026 13:18:44 +0100
Subject: [PATCH 173/180] docs: bootstrap specs ground truth (#5794)

* docs(specs): restore bootstrap after dev rewrite

* docs(specs): remove runtime inventory snapshot

* docs(specs): reconcile current dev truth

* docs(specs): document scheduled task actions as an owner-attribution source

Owner Attribution covered cookie, bearer-token and internal-loopback
requests. Scheduled task actions are a fourth source and behave
differently: _execute_action passes owner=task.owner off the stored
ScheduledTask row, so no request and no resolved principal are in
flight, and route-level require_user() never runs.

Webhook triggers are the sharp case. They are unauthenticated by
design with the token as the only credential and execute under the
stored task.owner.

Paths cite routes/task/task_routes.py, the canonical location after
the task subpackage move (#6081); routes/task_routes.py on current dev
is the backward-compat shim.

* docs(specs): add chained tasks to the trigger list, refresh dev stamp

Review feedback from RaresKeY on the previous commit.

"Every trigger path" was too broad: success-chained tasks are another
path into _execute_action. Added them with their own citation, and
noted that chaining additionally requires the target task to share
task.owner and rejects cycles, which is stricter than the trigger-side
checks. Softened the lead-in to "these trigger paths".

Line 56 still pointed at routes/task_routes.py for webhook credential
validation. That path is the backward-compat shim on current dev after
the task subpackage move (#6081); repointed to the canonical
routes/task/task_routes.py.

Stamp moved to dev@2a6b09b. Inspection backing that bump was scoped:
every file path cited in this spec was mechanically checked to resolve
on 2a6b09b, and every file:line in the Owner Attribution additions was
read against it. Behavioral claims elsewhere in the file were not
re-audited.

* docs(specs): correct SECURE_COOKIES description to match current behavior

Third of the stale details RaresKeY enumerated. The cookie section
described SECURE_COOKIES as purely opt-in, which stopped being true.

_secure_cookie() (routes/auth_routes.py:89) treats an explicit true or
false as authoritative and derives the Secure attribute from the
request otherwise, including when the variable is unset and when
docker-compose injects it present-but-empty. Either the connection
scheme or the first X-Forwarded-Proto hop being https is enough.

* docs(specs): refresh current dev truth

+# Specs DocumentMap
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+This folder is the compact implementation-truth map for humans and coding agents working on Odysseus. Read this file first, then open only the subsystem specs that match the work.
+
+Specs are living notes about current code shape and intended contracts. They are not product marketing, not PR planning, not templates, and not a replacement for source inspection or tests.
+
+This `_readme.md` is the DocumentMap and control document. It is intentionally exempt from subsystem `Scope` and `Current Gaps` sections; keep it limited to the quality contract, working rules, subsystem map, and cross-cutting update triggers.
+
+## Quality Contract
+
+Each subsystem spec should stay compact and useful under context pressure:
+
+- Start with `Last updated: dev@<short-sha> | YYYY-MM-DD`, using the
+  upstream `dev` commit the spec text was inspected against.
+- Use a concrete `Scope` section that names real files, route surfaces, frontend modules, data stores, and integration points.
+- Use domain-specific sections. Do not force every spec into the same headings when the subsystem needs `Streaming`, `Tool Results`, `Optional Dependencies`, `Current Gaps`, or another focused section.
+- State ownership clearly: which file owns a mapping, which layer only forwards state, and which caller requests behavior without owning implementation.
+- Include runtime behavior bullets for flows that matter.
+- Include "Current call sites include" when behavior is spread across many files.
+- Record transitional compatibility notes, especially `src/` versus `services/` duplication.
+- Record degraded, optional, or platform behavior where it changes runtime expectations.
+- Record policy/provenance where relevant: untrusted context, encrypted secrets, API token scopes, optional dependency/license implications, generated media, or user data.
+- End with `Current Gaps` only when there is a real known gap, not as filler.
+
+If code and specs disagree, treat code as ground truth. Update specs only when
+the current task explicitly includes spec maintenance or the PR intentionally
+includes specs; otherwise report the drift in the relevant issue, PR review, or
+project documentation.
+
+## Working Rules
+
+- Start here before substantial work.
+- Read the related subsystem spec before changing code in that area. For cross-cutting work, include the owning domain spec plus route/runtime, auth/security, persistence, frontend, tool/context, integration, and testing/devops specs as applicable.
+- Treat specs as read-only context during ordinary project work, PR review, and code review. Do not edit specs unless the user explicitly asks for spec work or the current PR intentionally includes spec changes.
+- During explicit spec-maintenance work, update the related spec when source inspection shows behavior, ownership, security boundaries, data shape, import paths, or implementation contracts have changed.
+- During ordinary work, record source/spec drift in the relevant issue, PR review, or project documentation instead of mutating specs.
+- Keep specs dense but readable. Prefer current facts and invariants over broad explanation.
+- Every non-index `specs/*.md` file should appear exactly once in the Subsystem Map with a one-line description and no dead link.
+- Specs contain implementation truth. Planning, research, branch notes, and decisions belong in tracked project docs. Drafts, audit reports, raw exports, and exploratory gap lists are not authoritative until promoted into tracked docs or specs.
+- Use repo source and these specs as the authority for Odysseus architecture. Do not treat global skill registries or external agent metadata as repo ground truth.

+
+## Agent Loop
+
+`src.agent_loop` owns agent prompt assembly, request-local current date/time insertion, tool retrieval, prompted tool-block handling, native tool-call consumption after `llm_core` normalizes provider events, multi-round execution, tool result insertion, final metrics, and fallback responses. It requests context from documents, skills, tool retrieval, and messages; it should not own domain-specific business logic for every tool. Its prompt rules now bias structured/long-form writing toward living documents, route active compose/email drafts back into existing email documents, and prefer first-class `web_search`/`web_fetch` tools over shell/Python/curl for current web lookups when web tools are enabled.
+
+`src.llm_core` owns provider payloads, native tool-schema emission, and provider stream parsing. `agent_loop` consumes normalized tool-call events and decides whether and how to execute them.
+
+Agent mode enters through chat routes, including auto-escalation from intent helpers, detached `agent_runs` streaming, resume/stop behavior, and frontend tool-event rendering.
+
+Guide-only/no-tools turns are runtime policy, not prompt advice. `src.tool_policy` detects strong latest-turn directives such as guide-only mode, no-tools mode, and explicit requests not to use tools; it builds a `ToolPolicy` that hides schemas, disables known native tools, disables MCP for that turn, skips tool retrieval, suppresses local/workspace context injection, blocks document streaming/teacher escalation, and gives `tool_execution` a final execution backstop.
+
+Plan mode is a read-only investigation path inside the same loop. It adds a denylist for known mutating tools, filters write/unknown MCP tools, prepends plan-mode instructions, and uses the `update_plan` tool only after a plan is approved for execution. The backend path still exists for compatibility, but current browser chat forces incoming `plan_mode` off and the old plan-window UI module is gone.
+
+Workspace mode is request-scoped. Admin chat can send a workspace directory selected through `static/js/workspace.js`; `agent_loop` injects that fact early in the prompt and `tool_execution` confines bash, python, read/write/edit-file, and code-navigation tools to that root. `routes.workspace_routes` owns admin-only browse/vet APIs, skips hidden/symlink directory traversal, caps listings, and rejects sensitive/root paths before a workspace reaches chat.
+
+## Tool Registry
+
+Tool registration is split:
+
+- `src.agent_tools` is now a package/facade. `TOOL_HANDLERS` maps native tool names to handler functions across filesystem, subprocess, web, document, interaction, model-interaction, background-job, session, and admin modules, while `TOOL_TAGS` keeps compatibility metadata and the global MCP manager handle;
+- `src.tools` owns domain do_* implementations for calendar, contacts, Cookbook, image, notes, research, search, system, and vault tools. `src.tool_implementations` is now a compatibility facade that re-exports those symbols and lazy-loads admin manage_* symbols to avoid circular imports;
+- `src.agent_tools.admin_tools` owns admin manage_* tools for endpoints, MCP, webhooks, tokens, and settings, including command validation for `manage_mcp`;
+- `src.tool_parsing._TOOL_NAME_MAP` owns aliases and prompted-block parsing;
+- `src.tool_schemas.FUNCTION_TOOL_SCHEMAS` and `function_call_to_tool_block()` own native schema and native-call conversion;
+- `src.tool_index.BUILTIN_TOOL_DESCRIPTIONS` owns retrieval text;
+- `src.tool_execution.execute_tool_block()` owns dispatch and hard execution gates;
+- `routes.model_routes.py` and frontend settings/admin surfaces expose global disabled-tool controls.
+
+When adding, removing, or renaming a tool, update the registry chain, execution dispatch, retrieval text, prompt wording, disabled-tool UI, and tests together.
+
+`src.tool_index.ALWAYS_AVAILABLE` is the retrieval catalog for high-frequency tools such as shell/python, web search/fetch, read/write/edit-file, code-nav, `manage_memory`, `ask_user`, `update_plan`, selected Cookbook serve controls, and `app_api`. Current prompt/schema assembly preserves only selected base tools unconditionally, then adds intent-, skill-, and retrieval-relevant tools so unrelated schemas do not flood small contexts.
+
+## Tool Retrieval And Execution
+
+`src.tool_index.ToolIndex` owns candidate retrieval using embeddings/keywords and cached index data. Security filtering is not its hard boundary: `agent_loop` hides unavailable schemas, and `tool_execution` blocks disabled, admin-only, and public-restricted calls before dispatch.
+
+`src.tool_execution` owns built-in tool execution, MCP dispatch, path confinement, background markers, output truncation, internal HTTP loopback, owner/admin checks, policy-blocked execution results, and formatting tool results for the model/UI. File tools support exact edit diffs, full-file writes, read line ranges, and workspace confinement. Code-navigation tools (`grep`, `glob`, `ls`) prefer `rg`/structured filesystem traversal over ad hoc shell commands. Uploaded-file context uses stable `attachment_ref` manifests and owner-checked URIs; a compatibility local path is exposed only after upload-root and tool-root confinement. Shared truncation, upload-handler registration, and MCP manager compatibility helpers live in `src.tool_utils`.
+
+Tool retrieval has domain-specific hooks beyond generic similarity: contact queries can surface `resolve_contact`/`manage_contact`; matched skills can add `manage_skills` and their required toolsets to the relevant tool set; explicit admin intents can include admin schemas so prompt text and native schema emission match.
+
+Interaction/session/model helper tools are native first-class tools, not prompt-only conventions. `ask_user` and `update_plan` live in `src.agent_tools.interaction_tools`, model delegation/listing helpers live in `model_interaction_tools`, session creation/list/send/manage helpers live in `session_tools`, and `manage_bg_jobs` lives in `bg_job_tools`.
+
+Prompted-tool parsing includes recovery paths for local/provider text leaks: bare JSON after a web-tool mention, OpenAI-style raw `{"function": ...}` payloads, StepFun/Gemma/DSML markup, Hermes/Qwen JSON bodies nested inside `tool_call` wrappers, and `<function_model><function_call>...</function_call><parameters>...</parameters></function_model>` wrappers from local MLX/Exo models. The Qwen bare end marker requires its pipe delimiter so ordinary text cannot terminate a tool block. Non-dict JSON arguments are rejected back to empty args instead of crashing the turn, common `tex` typos normalize to `text`, and delimiter scans are forward-only so unterminated tool markup cannot drive quadratic rescans. Executed raw tool JSON is stripped from assistant text afterward; this is still not a general-purpose JSON-command parser.
+
+Current call sites include:
+
+- agent mode tool calls from `src.agent_loop`;
+- MCP route configuration and built-in MCP registration;
+- background job monitoring and auto-continue;
+- skill tests, teacher escalation, scheduled tasks, and background follow-up loops;
+- UI-control and AI interaction helpers.
+
+## Streaming And Continuations
+
+Agent streaming emits normal content plus tool progress/output, document stream/update, ask-user choices, plan updates, budget, round exhaustion, loop-breaker, intent-nudge exhaustion, metrics, teacher escalation, research anchor, and finish/error events. Frontend chat stream code and detached replay depend on stable event names. If the stream generator closes while awaiting an in-flight tool, the loop cancels and awaits that tool task so subprocess-backed work is not left orphaned.
+
+Long-running bash jobs can be detached with background markers. `src.bg_jobs` owns persistent job state/result files; `src.bg_monitor` owns auto-continuation when jobs finish. Detached chat runs are in-memory and do not survive server restart, while background job state is disk-backed.
+
+Loop-breaker final-answer rounds, explicit repeated-tool/intent-nudge guard events, round-cap continuation signals, optional verifier retries, and teacher escalation are recovery behavior owned by `agent_loop` and `src.teacher_escalation`.
+
+Approval replay injects the sealed first tool result before the resumed model round. If that replay round has neither assistant prose nor reasoning, `_append_tool_results()` omits the empty assistant spacer so Anthropic-compatible payloads do not contain a rejected non-final empty assistant message; reasoning-only carriers remain a documented compatibility edge.
+
+## Security And Policy
+
+- `src.tool_security` owns non-admin blocked-tool decisions.
+- Non-admin users must not reach admin tools through agent mode, MCP, retrieval, or loopback calls.
+- Agent owner is passed from chat route `get_current_user(request)`. In `AUTH_ENABLED=false` mode this is `None`, not the `""` value returned by route dependencies. `blocked_tools_for_owner()`, schema hiding, and `execute_tool_block()` all use that owner.
+- Current dev tool security treats explicit `AUTH_ENABLED=false` as single-user even when an auth store exists, while auth-enabled pre-setup callers remain non-admin.
+- Path-based tools must remain confined to allowed roots and reject sensitive paths. Sensitive-path checks are case-insensitive and apply to direct file tools and code-navigation tools; `grep`/`glob`/`ls` must not become existence or content oracles for `.env`, SSH/GPG material, `id_rsa`, and similar denylisted paths.
+- Tool output is bounded/truncated where native execution owns the path, including displayed agent-tool output through the shared truncation helper. MCP output must be treated as untrusted; central MCP-output truncation before model re-entry remains a gap.
+- Provider-emitted native tool calls are requests, not authorization. `tool_execution` and route-level policy remain the authority.
+- `src.tool_capabilities` classifies each tool's effects and result integrity. Once external/workspace-untrusted content becomes model-visible, the request/session security context permits only explicitly low-impact tools without interruption and requires exact approval for high-impact, unknown, and arbitrary MCP calls.
+- `src.tool_approvals` seals an opaque, expiring exact first action plus server-only selected tools and continuation query to owner, session, origin run, tool content, workspace, capability snapshot, and—when relevant—document id/version/content digest. Chat choices grant the resumed task or the same chat session; both consume the exact first action, task scope bypasses the gate only during that resumed run, and chat scope is reconstructed only from a resolved card bound to the exact session id. The browser never receives selected tools/query and submits only task/chat/deny. Non-chat callers retain single-action behavior; new normal turns and superseding actions retire unresolved approvals without clearing taint.
+- Tool results that expose remote or stored untrusted content arm the gate even when their tool status is failed. Content-free failures and server-generated policy/approval placeholders do not. Native/provider tool messages and fenced results carry model-visible untrusted metadata/wrapping instead of relying on prompt wording alone.
+- Attachment-bearing document, note, and calendar tools owner-reserve internal
+  upload references before durable writes and fail without mutation when the
+  referenced upload is unavailable.
+- Guide-only/no-tools mode blocks tools before prompt assembly, before execution, and in chat preprocessing paths that would otherwise fetch context or start tool-backed research.
+- Plan mode is policy, not prompt advice: mutating native tools are disabled through schema-derived detection plus a static backstop, and write/unknown MCP tools are hidden and runtime-blocked for that turn.
+
+## Internal Loopback
+
+`do_app_api()` is implemented in `src.tools.system` and re-exported by `src.tool_implementations`. It owns generic app API loopback, OpenAPI discovery, method/path blocklists, and fixed local target behavior. `_internal_headers()` adds the process-secret internal-tool token and optional `X-Odysseus-Owner`; `core.middleware.require_admin()` and auth middleware own the corresponding bypass and owner-stamping rules. Route-specific owner handling must still be audited.
+
+## MCP
+
+`src.mcp_manager` owns configured MCP server lifecycle, discovered tool state, qualified MCP names, OpenAI schema conversion, call routing, generation invalidation, and connect/disconnect status. It supports stdio, SSE, and Streamable HTTP transports; Streamable HTTP can publish a `needs_auth` state and uses `src.mcp_oauth` for OAuth/OIDC-style authorization, token refresh, and encrypted token storage. Arbitrary MCP tools classify fail-high for approvals. `src.builtin_mcp` owns built-in server registration and the native-vs-MCP split. `mcp_servers/` owns server-specific tools for email, image generation, memory, RAG, and optional browser tooling.
+
+Native bash, python, file, web search, and web fetch tools continue through native fallback even when MCP is unavailable. Browser MCP is optional and can be skipped when cached Playwright/NPX packages are missing. Public users get no MCP schemas, and any `mcp__*` execution attempt must be blocked.
+
+MCP prompt/schema rendering includes server-provided input schemas, but names, types, and parameter hint text are sanitized and length-capped before entering the prompt. Per-server disabled tools filter listings, prompt descriptions, and function schemas; execution-time disabled-tool enforcement remains a separate hardening item.
+
+## Intent And Recovery Helpers
+
+`src.action_intents` owns deterministic chat-to-agent promotion hints and returns a category/reason so route logs can explain auto-escalation decisions. Explicit web-search language is category `web`; it can promote the turn into agent mode and narrow tools toward web search/fetch, but route policy requires explicit web-search enablement and honors explicit denial. It must avoid promoting explanatory questions into agent mode. `src.builtin_actions` owns scheduler/background actions outside the normal live agent loop. `src.teacher_escalation` owns recovery/escalation and skill-creation flows. `src.goal_based_extractor` is research-adjacent and should stay cross-referenced from research behavior rather than treated as ordinary tool execution.
+
+When an email reader is active, browser chat passes active email metadata and the agent loop injects it as protected, untrusted context so default reply/draft behavior targets the selected message. Active email compose documents are handled as existing email drafts rather than generic new-document requests.
+
+## Degraded Behavior
+
+- ToolIndex can degrade to keyword selection when embeddings, Chroma, index
+  warmup, or vector retrieval timeouts fail.
+- Agent mode can degrade from native function schemas to prompted fenced-block parsing based on provider/tool-support heuristics. Local Ollama `/v1` and native `/api` endpoints default to text tools unless the endpoint explicitly advertises `supports_tools`; `gpt-oss` remains text-tool by default unless the endpoint opts in.
+- MCP startup failure is non-critical; route/status surfaces expose per-server errors.
+- `ODYSSEUS_DISABLE_MCP`, missing `mcp`, uncached browser MCP packages, and per-server disabled tools can remove tools without blocking the app.
+- Global `builtin_browser` disable behavior may not currently match qualified `mcp__builtin_browser__*` tool names.
+
+## Current Gaps
+
+- Tool descriptions are duplicated across `FUNCTION_TOOL_SCHEMAS`, agent prompt sections, and `BUILTIN_TOOL_DESCRIPTIONS`.
+- Agent prompts remain heavy for small local context windows.
+- Some AI-control helpers are still globally wired from app startup rather than a narrower service layer.
+- Tool registry consistency is manual across handler maps, tags, aliases, schemas, retrieval descriptions, execution dispatch, settings/model routes, and frontend toggles.
+- MCP disabled-tool changes can stale-cache tool retrieval because disabled maps are not always an index generation input.
+- External MCP output still needs a single central size cap before model re-entry; untrusted-result metadata and the post-external-context action gate now cover the prompt-injection/authorization boundary.
+- Auth-disabled/no-login owner propagation is inconsistent between route dependencies and chat/agent execution, so tool-security and native tool storage behavior need dedicated regression coverage.
+- Agent tests mostly cover helpers and targeted regressions, including round-cap
+  and disconnect cancellation paths, but not an end-to-end fake-LLM
+  `stream_agent_loop` path with retrieval, native schemas, prompted blocks,
+  disabled/admin hiding, MCP tools, plan/workspace state, user-time context, and
+  tool-result SSE.

-# Architecture Runtime Inventory
-
-> **Purpose**: Phase 0 planning baseline for codebase readability improvements (#4071).
-> **Parent issue**: [#4082](https://github.com/odysseus-dev/odysseus/issues/4082)
-> **Last updated**: dev@b58af42 | 2026-06-16
-> **Status**: Draft — to be reviewed before follow-up slices open.
-> **Snapshot basis**: Importer / file / import-line counts are refreshed to `dev@b58af42` (2026-06-16) and are recomputable via the commands in §3.4. **Line counts** in §2.1 / §2.2 are a snapshot from an earlier baseline and drift as `dev` moves — recompute any of them with `wc -l <file>`. This inventory tracks structure and risk, not live metrics.
-
-This document maps the current runtime module structure, identifies high-risk boundaries, and recommends safe first refactor slices. It does **not** move files, change imports, or alter runtime behavior.

-**Heuristic**: Files > 2,000 lines with 20+ public symbols and many importers are the highest-risk splits. Files 1,000–2,000 lines are medium-risk if tightly coupled.
-
-### 2.2 Frontend
-
-| File | Lines | Concern |
-|------|-------|---------|
-| `static/style.css` | **36,653** | Entire app CSS in one file (tracked separately in #2617) |
-| `static/js/document.js` | **9,776** | Single JS file for document functionality |
-| `static/js/slashCommands.js` | 6,498 | |
-| `static/js/settings.js` | 5,266 | |
-| `static/js/emailLibrary.js` | 5,217 | |
-| `static/js/notes.js` | 5,124 | |
-| `static/js/chat.js` | 4,985 | |
-| `static/app.js` | 4,090 | |
-
-**Note**: Frontend modularization is tracked separately in #2617 (CSS) and is not the focus of this Phase 0 inventory. Frontend is listed here for completeness but follow-up slices should target Python backend boundaries first.

-## 3. Import Dependency Graph
-
-### 3.1 Who Depends on `core/database.py`
-
-**102 files** import from `core.database` — this is the most depended-upon module:
-
-- All route handlers (`routes/*.py`)
-- Most `src/*.py` files
-- `core/session_manager.py`, `core/auth.py`
-- Multiple test files
-
-**Implication**: Any split of `core/database.py` is the highest-risk refactor. It should be tackled **last**, never first.
-
-### 3.2 Who Depends on `src/tool_implementations.py`
-
-**17 files** import from `src.tool_implementations`:
-- `src/agent_loop.py`, `src/builtin_actions.py`, `src/tool_index.py`
-- `src/task_scheduler.py`, `src/tool_policy.py`
-- Various tests
-
-### 3.3 Who Depends on `src/agent_loop.py`
-
-**22 files** import from `src.agent_loop`:
-
-- `src/tool_policy.py`, `src/teacher_escalation.py`, `src/bg_monitor.py`
-- `src/task_scheduler.py`
-- Multiple test files
-
-### 3.4 Cross-Layer Import Violations
-
-**`src/` importing from `routes/`** (backwards dependency — domain logic depending on HTTP layer):
-
-```
-src/tool_implementations.py ──→ routes/calendar_routes.py
-src/tool_implementations.py ──→ routes/cookbook_helpers.py
-src/tool_implementations.py ──→ routes/email_helpers.py
-src/tool_implementations.py ──→ routes/email_pollers.py
-src/tool_implementations.py ──→ routes/email_routes.py
-src/tool_implementations.py ──→ routes/model_routes.py
-src/tool_implementations.py ──→ routes/note_routes.py
-src/tool_implementations.py ──→ routes/prefs_routes.py
-```
-
-> These are **runtime imports** (inside function bodies, not at module top), which mitigates circular import risk but indicates fuzzy layer boundaries. Function-level inline imports from the HTTP layer into business logic are a code smell.
-
-**Import counts (top-level)**:
-| Direction | Count | Notes |
-|-----------|-------|-------|
-| `routes/` → `src/` | **374** | Expected: HTTP handlers call domain logic |
-| `routes/` → `core/` | **126** | Expected: handlers access DB models |
-| `src/` → `routes/` | **31** | **Unexpected**: domain logic reaching into HTTP layer (direct grep of import lines referencing `routes/`) |
-| `src/` → `core/` | **106** | Acceptable but could be reduced with a data-access layer |
-
-> **How the metrics in this document are computed** — recompute against current `dev` before treating any count as authoritative (the tree drifts; these numbers are a snapshot, not a live value):
-> - `src/` flat `.py` files: `find src -maxdepth 1 -name '*.py' | wc -l`
-> - `tests/` test files: `find tests -name 'test_*.py' | wc -l`
-> - `core.database` importers: `grep -rlE '(from|import) +core\.database' --include='*.py' . | grep -v core/database.py | wc -l`
-> - `src.agent_loop` importers: `grep -rlE '(from|import) +src\.agent_loop' --include='*.py' . | grep -v src/agent_loop.py | wc -l`
-> - Cross-layer import lines: `grep -rhE '(from|import) +<pkg>' --include='*.py' <dir>/ | wc -l` (e.g. `(from|import) +routes` over `src/`)

-## 4. Route Ownership Map
-
-Routes can be grouped into logical feature domains. Current flat structure obscures these boundaries:
-
-| Domain | Route Files | Total Lines | Review Complexity |
-|--------|-------------|-------------|-------------------|
-| **Email** | `email_routes.py`, `email_helpers.py`, `email_pollers.py` | 5,936 | HIGH — most complex domain |
-| **Chat / Agent** | `chat_routes.py`, `chat_helpers.py`, `shell_routes.py`, `codex_routes.py`, `skills_routes.py` | 6,365 | HIGH — core interaction surface |
-| **Cookbook** | `cookbook_routes.py`, `cookbook_helpers.py`, `cookbook_output.py` | 4,110 | MEDIUM |
-| **Model / LLM** | `model_routes.py`, `assistant_routes.py`, `copilot_routes.py` | 2,764 | MEDIUM |
-| **Calendar / Contacts** | `calendar_routes.py`, `contacts_routes.py` | 2,336 | MEDIUM |
-| **Documents** | `document_routes.py`, `document_helpers.py` | 1,954 | LOW |
-| **Auth** | `auth_routes.py`, `api_token_routes.py`, `device_flow.py` | 1,171 | LOW |
-| **Tasks** | `task_routes.py` (standalone) | 1,157 | LOW |
-| **Session** | `session_routes.py` (standalone) | 1,287 | LOW |
-| **Gallery** | `gallery_routes.py`, `gallery_helpers.py` | 1,896 | LOW |
-| **Memory** | `memory_routes.py` | — | LOW |
-| **Research** | `research_routes.py` | — | LOW |
-| **MCP** | `mcp_routes.py` | — | LOW |
-| **Notes** | `note_routes.py` | — | LOW |
-| **Other** | `prefs_routes.py`, `upload_routes.py`, `vault_routes.py`, `webhook_routes.py`, `workspace_routes.py`, `search_routes.py`, `history_routes.py`, `hwfit_routes.py`, `preset_routes.py`, `signature_routes.py`, `backup_routes.py`, `cleanup_routes.py`, `diagnostics_routes.py`, `embedding_routes.py`, `emoji_routes.py`, `font_routes.py`, `stt_routes.py`, `tts_routes.py`, `compare_routes.py`, `personal_routes.py`, `editor_draft_routes.py`, `admin_wipe_routes.py`, `chatgpt_subscription_routes.py` | 2,000+ | LOW individual, HIGH cumulative |

-## 5. Tool Registry & Implementation Boundaries
-
-### 5.1 Current Tool Architecture
-
-| Component | File | Lines | Role |
-|-----------|------|-------|------|
-| Tool schemas | `src/tool_schemas.py` | 1,392 | JSON Schema tool definitions (Duck-TypedDict) |
-| Tool index | `src/tool_index.py` | 542 | RAG-based tool retrieval from ChromaDB |
-| Tool implementations | `src/tool_implementations.py` | 4,032 | 33 `do_*` functions — all tool execution logic |
-| Tool security | `src/tool_security.py` | — | Owner-scoped tool blocking |
-| Tool policy | `src/tool_policy.py` | — | Guide-only directive, plan-mode disabled tools |
-| Tool utils | `src/tool_utils.py` | — | Shared tool helpers |
-
-### 5.2 Tool Implementation Categories
-
-The 33 `do_*` functions in `tool_implementations.py` fall into natural domain groups — the basis for slice 1's split in §6.2:
-
-| Category | `do_*` functions | Count |
-|----------|------------------|-------|
-| **System / config** | `do_manage_skills`, `do_manage_tasks`, `do_manage_endpoints`, `do_manage_mcp`, `do_manage_webhooks`, `do_manage_tokens`, `do_manage_settings`, `do_api_call`, `do_app_api` | 9 |
-| **Cookbook / model serving** | `do_download_model`, `do_serve_model`, `do_list_served_models`, `do_stop_served_model`, `do_tail_serve_output`, `do_list_downloads`, `do_cancel_download`, `do_search_hf_models`, `do_adopt_served_model`, `do_list_cookbook_servers`, `do_list_serve_presets`, `do_serve_preset`, `do_list_cached_models` | 13 |
-| **Notes** | `do_manage_notes` | 1 |
-| **Calendar** | `do_manage_calendar` | 1 |
-| **Search** | `do_search_chats` | 1 |
-| **Research** | `do_manage_research`, `do_trigger_research` | 2 |
-| **Contacts** | `do_resolve_contact`, `do_manage_contact` | 2 |
-| **Vault** | `do_vault_search`, `do_vault_get`, `do_vault_unlock` | 3 |
-| **Image** | `do_edit_image` | 1 |
-| | **Total** | **33** |
-
-> Low-level tools (filesystem, subprocess, web fetch, document parsing) live in `src/agent_tools/`, **not** in `tool_implementations.py` — out of scope for this split.
-
----
-
-## 6. Risk Assessment & Candidate Slice Ranking
-
-> **Candidate proposals, not a committed plan.** The rankings, package shapes (e.g. `src/pkg/`, `src/domain/`, `src/infra/`, `src/api/`), split ordering, and route-grouping strategy below are **options for maintainer discussion**. Per #4082/#4071, slice ownership and order are settled by maintainers before any follow-up PR. §1–§3 above are the factual current-state inventory.
-
-### 6.1 Risk Scale
-
-| Level | Criteria |
-|-------|----------|
-| **LOW** | File has ≤3 importers AND ≤500 lines, OR is a pure refactor with clear boundaries |
-| **MEDIUM** | File has 4–15 importers OR 500–1,500 lines |
-| **HIGH** | File has 16+ importers OR >2,000 lines, OR has cross-layer import violations |
-
-### 6.2 Ranked Split Candidates
-
-| Priority | Target | Risk | Rationale |
-|----------|--------|------|-----------|
-| **1** | `src/tool_implementations.py` → `src/tools/*.py` | **MEDIUM** | 4,032 lines → ~10 files by tool category. Already has natural boundaries. 17 importers, tracked in #3629. Use `__init__.py` shim to keep existing imports working. |
-| **2** | `routes/` → domain subdirectories (one domain per PR) | **MEDIUM** | 54 flat files. Done **one domain at a time** (e.g. a standalone PR for the email domain, then chat, …), not a broad reorganization — route modules carry helper imports, registration assumptions, and test import paths. |
-| **3** | `src/agent_loop.py` → `src/agent/loop.py` + submodules | **MEDIUM-HIGH** | 2,961 lines, 24 functions. Can extract prompt building, classification, verification, and runaway detection. Tracked in #3266. |
-| **4** | `src/` → `src/pkg/`, `src/domain/`, `src/infra/`, `src/api/` | **MEDIUM** | Structural reorganization. Split flat `src/` into layered packages. Must come after routes and tools are stable. |
-| **5** | `routes/email_*.py` consolidation | **LOW** | Already grouped by filename prefix. Low-risk cleanup within the email domain. |
-| **6** | `core/database.py` → `src/infra/database/models/*.py` | **HIGH** | 28 classes, 102 importers. Highest-risk split. Must be **last** in any sequence. Requires careful import shim strategy. |
-| **7** | Frontend CSS modularization | **MEDIUM** | 36,653 lines. Tracked in #2617. Separate timeline from backend work. |
-| **8** | Frontend JS modularization | **MEDIUM** | 9,776 lines in `document.js`. Introduce ES modules at minimum. |
-
-### 6.3 Candidate First 3 Behavior-Preserving Slices
-
-**Slice 1: Split `tool_implementations.py`** (Lowest-risk high-impact)
-
-- Create `src/tools/` package with one file per tool category
-- Add `src/tools/__init__.py` re-exporting all symbols with current names
-- Update 17 importers to use new paths (can be deferred via shim)
-- Validation: `python -m pytest tests/ -x -q` + manual smoke test of tool execution
-- Reference: #3629
-
-**Slice 2: Group `routes/` by domain** (one domain per PR, not a broad sweep)
-
-Route modules carry helper imports, router registration assumptions, and test import paths, so this must be done **one domain at a time** rather than as a single reorganization PR. Example sequence (each its own PR):
-
-- PR 2a: move the **email** domain (`email_routes.py`, `email_helpers.py`, `email_pollers.py`) → `routes/email/` + shim
-- PR 2b: move the **chat/agent** domain → `routes/chat/` + shim
-- PR 2c: move the **cookbook** domain → `routes/cookbook/` + shim
-- …and so on per domain from §4
-
-Each PR: add `__init__.py` re-exporting old names, update `app.py` router imports, validation `python app.py` starts clean. **No behavior change** — pure file reorganization.
-
-**Slice 3: Extract `agent_loop.py` submodules** (Improve reviewability)
-
-- Move prompt assembly → `src/agent/prompt.py`
-- Move request classification → `src/agent/classifier.py`
-- Move sub-agent verification → `src/agent/verifier.py`
-- Move runaway detection → `src/agent/runaway.py`
-- Move context management → `src/agent/context.py`
-- Keep `src/agent/loop.py` as the main orchestration module
-- Validation: `python -m pytest tests/test_agent_loop.py tests/test_loop_breaker_runaway.py -v`
-
----
-
-## 7. Safety Guardrails for Follow-Up Work
-
-Per maintainer guidance in #4082 and #4071:
-
-- [ ] **One domain/slice per PR** — never mix multiple reorganizations
-- [ ] **No behavior changes** mixed with file moves — pure reorganization only
-- [ ] **Keep compatibility shims** — `__init__.py` re-exports for all existing import paths
-- [ ] **Add or identify focused tests** before risky splits
-- [ ] **Do not start with `core/database.py`** or broad route movement unless this inventory shows a safe boundary
-- [ ] **Prefer small, reviewable slices** over large restructures
-- [ ] **No packaging/runtime/tooling migration** mixed into file moves
-- [ ] **No frontend framework migration** inside this stabilization lane
-- [ ] **Validate with `python -m compileall`** — every PR must pass CI checks
-- [ ] **Validate with `pytest`** — run the full test suite before opening each PR
-
----
-
-## 8. Validation Commands
-
-Each follow-up PR should be verifiable with these commands before submission:
-
-```bash
-# Syntax check — must pass with zero errors
-python -m compileall src/ routes/ core/ conf/
-
-# Full test suite — must match baseline pass rate
-python -m pytest tests/ -x -q
-
-# Import shim verification — existing import paths must still work
-python -c "from src.tool_implementations import do_search_chats; print('OK')"
-
-# App startup smoke test (if backend touched)
-timeout 5 python app.py 2>&1 | head -5 || true
-```
-
----
-
-## 9. Open Questions
-
-1. Is `#2538` (specs ground truth) the canonical behavior map baseline, and should this inventory be kept in sync with those specs once merged?
-2. Should route grouping follow the domain map proposed here, or is there a different taxonomy preferred by maintainers?
-3. For the `tool_implementations.py` split (#3629), is the tool categorization in §5.2 acceptable, or should it follow a different grouping?
-4. Should compatibility shims (`__init__.py`) be temporary (removed in a follow-up wave) or permanent?
-5. Should an ADR (Architecture Decision Record) document be started to track decisions made during this process?
-
----
-
-## 10. Future Direction (NOT current state)
-
-The following are **future refactor targets** (candidate directions **pending maintainer agreement**, not committed), recorded here so this inventory does not imply they exist today. None of them are present in the current `dev` tree:
-
-- `main.py` — proposed rename of the `app.py` entrypoint. Today the app boots via `app.py`.
-- `src/agent/` — proposed package to hold `agent_loop.py` submodules (prompt/classifier/verifier/runaway/context). Today `agent_loop.py` is a single flat file in `src/`.
-- `src/infra/`, `src/domain/`, `src/pkg/`, `src/api/` — proposed layered reorganization of the flat `src/` directory (slice 4 in §6).
-
-These become real only when the corresponding slices land.

+# Auth And Security
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers current security and trust-boundary behavior in:
+
+- `core/auth.py`;
+- `core/middleware.py`;
+- `core/log_safety.py`;
+- `core/database.py`;
+- `app.py` auth middleware and token cache;
+- `src/auth_helpers.py`;
+- `src/owner_identity.py`;
+- `src/tool_approval_scopes.py`, `src/tool_approvals.py`, and `src/tool_capabilities.py`;
+- `src/tool_security.py`;
+- `src/tool_execution.py`;
+- `src/task_action_policy.py`;
+- `src/prompt_security.py`;
+- `src/url_safety.py` and `src/url_security.py`;
+- `src/host_docker_access.py`;
+- `src/attachment_refs.py` and upload lifecycle enforcement in
+  `src/upload_handler.py` / `routes/upload_routes.py`;
+- `src/secret_storage.py`;
+- `src/api_key_manager.py`;
+- `src/integrations.py`;
+- `src/webhook_manager.py`;
+- `src/generated_images.py`;
+- `scripts/diffusion_server.py`;
+- `scripts/mlx_image_server.py`;
+- `companion/routes.py` and `companion/pairing.py`;
+- `routes/auth_routes.py`, `routes/api_token_routes.py`, and canonical `routes/vault/vault_routes.py` plus its top-level compatibility shim;
+- admin-gated call sites in route files;
+- `THREAT_MODEL.md` and `SECURITY.md`.
+
+## Trust Boundary
+
+Odysseus is a trusted-user private-network app. Admins intentionally have powerful local capabilities: shell, files, email, calendar, MCP, model serving, vault, settings, and API token management. The security model prevents unauthenticated access, non-admin escalation, prompt-injection through untrusted content, and accidental exposure of internal services.
+
+`THREAT_MODEL.md` owns high-level security framing, but implementation claims here should be verified against current code when the threat model is stale. This spec records the implementation map that contributors should check before changing auth or untrusted-context flows. Security-header runtime details live in `runtime.md`.
+
+## Auth Ownership
+
+- `core.auth.AuthManager` owns users, password hashing, TOTP/backup codes, reserved usernames, privilege defaults, admin promote/demote state, and auth settings stored in `data/auth.json`. Auth config/setup mutations are lock-guarded, and session tokens are persisted separately in `data/sessions.json` behind their own lock.
+- `app.py` owns request-time auth middleware, token-cache rebuild/invalidation, auth exemptions, API-token verification, and internal-tool identity stamping.
+- `routes/auth_routes.py` owns HTTP endpoints for setup, signup/login/logout, 2FA, users, privileges, auth features, and integration settings.
+- `core.middleware.require_admin()` owns the normal admin gate. Local wrappers must document and test any intentional divergence from that boundary.
+- `src.auth_helpers.effective_user()` owns cookie/API-token owner attribution for selected route code. `require_user()` owns route-level degraded user resolution, `require_privilege()` owns privilege checks, and `owner_filter()` owns shared/null-owner query compatibility.
+
+Reserved usernames include request-only sentinels `internal-tool`, `api`, `demo`, and `system`, plus the storage-only Default/Local owner `__odysseus_local__`. Loaded auth data drops reserved user records, and create/rename flows must reject real users with those names. `src.owner_identity` is the canonical owner vocabulary and `auth_disabled()` parser.
+
+## Auth Runtime Flow
+
+`AuthMiddleware` is the outer request gate because FastAPI middleware executes in reverse add order. It can return API `401` JSON or browser `/login` redirects before timeout/security-header middleware reaches the route.
+
+Public/auth-exempt surfaces are limited to setup, signup/login/logout/status, feature/settings/integration preset reads, health/version/login, `/static/*`, and task webhook trigger paths. `routes/task/task_routes.py` owns validation of `POST /api/tasks/{task_id}/webhook/{token}` path credentials.
+
+Login issues an `HttpOnly`, `SameSite=Lax` cookie with a seven-day max age when "remember" is enabled. `_secure_cookie()` (`routes/auth_routes.py:89`) decides the `Secure` attribute: an explicit `SECURE_COOKIES` of `true` or `false` is authoritative, and any other value, including unset and the present-but-empty value docker-compose injects, derives it from the request, marking the cookie `Secure` when the connection scheme or the first `X-Forwarded-Proto` hop is https. TOTP is checked before session issuance. Logout, password changes, user deletion, rename flows, expired sessions, and deleted-user sessions must keep revocation/migration behavior intact.
+
+Deleting a user revokes that user's browser sessions and API-token rows, then the admin delete route invalidates the in-memory bearer-token cache so already-cached tokens stop authenticating.
+
+Rename first changes the auth username, then migrates owner-bearing DB rows and disk-backed stores. Current rename coverage includes user preferences, active/disk research state, `memory.json`, upload metadata and owner-qualified upload index keys, skills frontmatter/usage state, cached browser sessions, and API-token cache invalidation. If owner migration fails after the auth rename, the route attempts to roll auth back to the old username instead of leaving a split identity.
+
+Admin promotion/demotion is a live auth flag change through `AuthManager.set_admin()` and `PUT /api/auth/users/{username}/admin`. Demotion refuses to remove the last admin, permits self-demotion when another admin remains, restores the pre-admin privilege map when available, and does not revoke sessions or API tokens because later admin checks read the current `is_admin` flag.
+
+## Owner Attribution
+
+Cookie requests use the real username. Bearer-token requests are stamped as `request.state.current_user = "api"` plus `api_token_owner`, `api_token_scopes`, and token id. Routes that support API-token access must explicitly use `effective_user()` or route-local scope helpers instead of treating `"api"` as an owner.
+
+Internal loopback calls may stamp `current_user = "internal-tool"` or a validated `X-Odysseus-Owner` username. Network/proxy validation for that bypass lives in `app.py`; `require_admin()` trusts the stamped sentinel or raw internal header and should be used behind equivalent middleware control.
+
+Missing-owner values remain state-dependent at legacy call sites, but new storage-facing code has one normalization contract:
+
+- Auth-enabled, configured auth with no `current_user` is unauthenticated and should fail closed at route dependencies.
+- `AUTH_ENABLED=false` is an explicit local single-user/no-login mode. Existing route dependencies can still return `""`, and admin gates allow the local operator. `effective_storage_owner()` and `storage_owner_for_request()` normalize an absent owner to `__odysseus_local__` only in this mode.
+- Chat/agent code that reads `get_current_user(request)` directly gets `None` when auth middleware is disabled, because no middleware stamps request state.
+- SQL `NULL`/JSON missing owners remain legacy/shared compatibility data, not the same thing as a logged-out authenticated caller.
+- `"api"` and `"internal-tool"` are request sentinels. They must not be persisted as normal storage owners unless a route explicitly defines that behavior.
+- `__odysseus_local__` is a valid storage owner but never a login or request sentinel. Adoption is incremental: callers that do not use the storage-owner helper can still expose older `None`/empty/null compatibility behavior.
+
+Authenticated `manage_tasks` mutations require an exact stored task-owner
+match and reject both cross-owner and legacy null-owner rows. The `owner=None`
+agent path keeps deliberate auth-disabled single-user compatibility, including
+unscoped list/create/mutation behavior.
+
+Owner-scoped route code should use `require_user()` or equivalent policy before querying per-owner data. Current note CRUD/reorder/reminder routes do this so an auth-enabled request that reaches the route without identity returns `401` instead of falling into single-user/null-owner compatibility behavior.
+
+Scheduled task actions attribute differently again. `_execute_action` (`src/task_scheduler.py:1231`) invokes the action with `owner=task.owner` read from the stored `ScheduledTask` row, so no request and no resolved principal are in flight. These trigger paths converge there: schedule, event bus, manual run (`routes/task/task_routes.py:865`), the `manage_tasks` agent tool (`src/tools/system.py:469`), webhook triggers (`routes/task/task_routes.py:1045`), which are unauthenticated by design with the token as the only credential and execute under the stored `task.owner`, and success-chained tasks (`src/task_scheduler.py:1063-1074`), which additionally require the chained target to share `task.owner` and reject cycles. Trigger-side ownership checks use the `if user and task.owner != user` shape, so a falsy caller skips them. Action bodies that reach owner-scoped storage must treat `task.owner` as the authority; route-level `require_user()` never runs on this path.
+
+## API Tokens And Scoped Integrations
+
+`routes/api_token_routes.py` owns token CRUD and scope normalization. Partial updates preserve existing scopes unless new scopes are supplied, write scopes imply the matching read scopes where applicable, and Cookbook scopes are part of the normalized scope set. `app.py` caches active token prefix rows and verifies bearer tokens with bcrypt. API-token requests set `request.state.current_user = "api"` plus token owner/scopes.
+
+Current call sites include Codex/Claude scoped APIs, `/api/v1/chat`, webhooks, selected session routes, companion pairing, and external integrations. `/api/codex/*` and `/api/v1/chat` enforce route-local scopes; companion and selected session routes use owner attribution. `companion/pairing.py` can mint chat-scoped tokens outside normal token CRUD.
+
+Admin token CRUD is cookie/admin gated. Update/delete operations check token ownership, and cache rebuild ignores active tokens whose owner no longer maps to a known auth user. Scoped route code must use the token owner and declared scopes instead of falling back to cookie-user assumptions.
+
+## Internal Tool Loopback
+
+Agent tools call admin-gated HTTP routes through an in-process loopback. `core.middleware.INTERNAL_TOOL_TOKEN` owns the random per-process secret. `app.py` only accepts this bypass from direct loopback clients without proxy-forwarding headers.
+
+`src.tool_security` owns non-admin tool blocking. Non-admin users must not reach admin tools through agent mode, MCP tools, or loopback calls.
+
+`src.tool_security.owner_is_admin_or_single_user()` treats explicit `AUTH_ENABLED=false` as intentional single-user mode even when an auth store already exists, while keeping pre-setup auth-enabled callers non-admin.
+
+Current admin gates include `require_admin()` call sites across admin wipe, backup, contacts, Cookbook, diagnostics, embeddings, MCP, model, personal docs, presets, skills, uploads, vault, webhook, and companion routes. Local wrappers also exist in auth routes, shell routes, and task action policy; changes to those wrappers need the same trust-boundary review as `require_admin()`. Scheduled task action policy treats `run_local`, `run_script`, `ssh_command`, and `cookbook_serve` as admin-only action tasks across create/update/manual-run/webhook/scheduler execution.
+
+`tidy_research` can remove only empty or unparseable research JSON. Because a broken file has no trustworthy owner stamp, the action checks `owner_is_admin_or_single_user()` before enumerating files; regular users and the pre-setup window cannot run that global unattributable-file sweep.
+
+## Untrusted Context Policy
+
+`src.prompt_security` owns the model-facing untrusted data contract:
+
+- `UNTRUSTED_CONTEXT_POLICY` states the policy in system prompt text.
+- `untrusted_context_message(label, content)` wraps external content as user-role data with `metadata.trusted = False`, provenance metadata, and a default `tool_gate_untrusted` marker. Guard-like labels/content are escaped so source text cannot counterfeit the wrapper boundary.
+
+Current untrusted surfaces include fetched URLs, web results, emails, memories, skills, notes, documents, active editor content, and tool output sourced from outside the server. Injecting those as trusted system instructions is a security bug.
+
+`src.tool_capabilities` classifies native and MCP tools by effects and result integrity. After external/workspace-untrusted context becomes model-visible, `ToolRunSecurityContext` keeps a server-owned taint for the session turn: only explicitly low-impact tools can run immediately, while write, execute, network-egress, UI/external-side-effect, admin, destructive, unknown, and arbitrary MCP actions require exact approval. Failed tools can still arm the gate when their result carries remote or stored payload; content-free failures and server-generated blocked/approval placeholders do not.
+
+`src.tool_approvals` owns opaque approvals sealed to the owner, session, origin run, exact first tool name/content, workspace, capability effects/result integrity, selected continuation tool set/query, and expiry. Document actions additionally seal document id, version, content digest, and workspace. Chat cards offer task scope, chat-session scope, or deny: both allow choices consume and execute the exact sealed first action after current-policy/freshness checks, task scope bypasses the gate only for the resumed task, and chat-session scope persists a resolved session-bound grant for later turns in that same chat. The browser submits only the opaque decision and cannot replace the sealed action, selected tools, query, composer text, or attachments. Non-chat callers retain single-action scope. A new ordinary turn or superseding action retires an unresolved approval without clearing taint.
+
+## URL, Path, And Secret Policy
+
+- `src/url_security.py` owns public HTTP(S) validation for integration/API-token supplied URLs. It should fail closed for private IP, loopback, invalid scheme, and unsafe redirect targets.
+- `src/url_safety.py` owns local-first outbound URL safety for model endpoints and similar local services. Loopback/LAN can be allowed by default, and private-IP blocking is an explicit caller policy. Strict `block_private=True` also rejects RFC 6598 shared/CGNAT space (`100.64.0.0/10`) explicitly because Python does not classify that range as private.
+- `core.log_safety.redact_url()` strips URL userinfo, query strings, and fragments before endpoint URLs enter logs. Model, chat/research endpoint, contact/CardDAV, and similar diagnostics should use this helper instead of logging raw admin-configured URLs.
+- `src.webhook_manager` validates webhook URLs at create and delivery time,
+  rejects private/internal targets, disables redirects, and pins delivery to
+  the public IP set that passed validation immediately before the request.
+- `src.integrations` owns admin-configured integration base URLs and secret
+  masking. `api_call` accepts only relative paths, rejects link-local/metadata destinations through `src.url_safety`, can additionally block RFC1918/loopback/private targets with `INTEGRATION_API_BLOCK_PRIVATE_IPS=true`, and pins requests to the IP set that passed SSRF validation while preserving the intended Host/TLS identity.
+- `src.outbound_fetch` owns reusable public-URL classification, validates every redirect hop, rejects private/local resolved addresses, and pins the HTTP connection to the validated public IP while preserving original URL/SNI/Host semantics. `services.search.content` adapts that transport for extraction and caching.
+- Path-based tools, upload/document/gallery/signature/generated-image routes, embedding cache paths, and research JSON helpers must stay confined to allowed roots and owner-scoped files. Native file/code-navigation tools also apply a case-insensitive sensitive-path denylist so `grep`, `glob`, `ls`, direct reads, and writes cannot reveal `.env`, SSH/GPG material, private-key filenames, or similar secret paths.
+- Durable upload references are owner-reserved before chat/session, document,
+  note, or calendar writes. Cleanup scans every current durable reference
+  surface and fails closed on incomplete discovery or inconsistent upload-index
+  state rather than deleting a possibly live upload.
+- File-backed SQLite startup restricts `app.db` and existing rollback/WAL/SHM
+  sidecars to `0600` on POSIX after resolving the real path from the parsed
+  engine URL. Windows, in-memory, and non-SQLite databases are excluded, and
+  failed POSIX restriction is logged as a secret-file warning.
+- Secret-like DB columns use `EncryptedText` or `src.secret_storage`. Email passwords and Google OAuth mail tokens are encrypted manually in `EmailAccount` string columns; Google OAuth state is HMAC-signed and callback writes are owner-checked before token storage. `src.api_key_manager` keeps provider API keys encrypted in `data/api_keys.json`, writes by loading the raw encrypted dict so saving one provider does not rewrite other providers' keys as plaintext, and restricts local key-file permissions where the platform supports chmod. Vault state in `data/vault.json` is a chmod-restricted JSON secret store, not Fernet-encrypted DB storage. Do not log or return decrypted secrets except for intentional admin vault retrieval flows with audit/reason checks.
+- `.env` files are secrets-only inputs and should not be read or printed during agent work.
+
+`scripts/diffusion_server.py` is a local model-serving helper with its own web surface. It defaults CORS to deny, installs a trusted-host allowlist for loopback/bind addresses, and only extends Host/CORS through explicit CLI flags.
+
+`scripts/mlx_image_server.py` serves exactly the model selected when the process starts. OpenAI-compatible request `model` fields are accepted but ignored for generation and edits, so an unauthenticated caller cannot select another local directory or Hugging Face repository and drive model-specific script/bridge execution.
+
+Host Docker socket access is a high-trust admin/deployment choice, not a normal container capability. Default Docker Compose does not mount `/var/run/docker.sock`; `src.host_docker_access` only reports local Docker available inside a container when `ODYSSEUS_ENABLE_HOST_DOCKER=true` and the socket exists. Remote SSH Docker/Cookbook workflows remain the safer default.
+
+## Degraded And Compatibility Behavior
+
+- `AUTH_ENABLED=false` skips `AuthMiddleware` and `src.auth_helpers.require_user()` returns `""` from any host. This preserves local single-user/no-login operation; it is not permission for auth-enabled logged-out callers. Storage code that adopts `storage_owner_for_request()` receives the reserved Default/Local owner; direct `get_current_user()` readers still receive `None`. Owner-scoped routes that tolerate no-login mode should call the appropriate route or storage helper so auth-enabled anonymous requests fail closed.
+- First-run setup mode redirects browser requests to `/login`, returns API `401 Setup required`, and keeps setup/status/login surfaces auth-exempt. Setup/signup/login are rate-limited; status is exempt but not rate-limited. Route helper fallbacks only tolerate unconfigured anonymous access from loopback.
+- User privilege checks distinguish legacy empty `allowed_models=[]` from explicit no-model access through `allowed_models_restricted=True`.
+- `LOCALHOST_BYPASS` in `app.py` only applies to direct loopback clients and excludes proxy/tunnel headers. Helper fallback code is weaker and should not be treated as the primary bypass boundary.
+- Legacy migrations claim null-owner SQL/JSON data for the primary admin when possible, and startup repeats a null-owner sweep hourly. Remaining null-owner rows are surface-specific compatibility data that must be deliberately included, no-oped for single-user mode, or rejected for strict ownership gates.
+- `.env` is loaded with `utf-8-sig`, so Windows BOM auth flags still parse.
+
+## Current Gaps
+
+- There is no shell/filesystem sandbox for admin tools.
+- Token scopes remain coarse for some surfaces.
+- `app.py` AuthMiddleware lacks direct regression coverage for bearer-token state/cache behavior, trusted-loopback proxy-header rejection, and internal-tool owner stamping.
+- Codex/Claude scoped route enforcement still needs stronger regression coverage.
+- `THREAT_MODEL.md` still has stale token-scope and `/api/v1/chat` SSRF gap text that should be reconciled with current route validation.
+- The Default/Local owner contract is canonical but only incrementally adopted; route helper `""`, chat/agent `None`, SQL/JSON null-owner compatibility, and calendar fallback owner behavior still need domain-by-domain migration decisions.

+# Calendar, Tasks, And Notes
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers calendar, reminders, tasks, assistant runs, and notes in:
+
+- app route wiring, auth exemptions, and scheduler startup in `app.py`;
+- canonical database models in `core/database.py`, with `src/database.py` as a compatibility re-export;
+- `routes/calendar_routes.py`, `src/caldav_sync.py`, and `src/caldav_writeback.py`;
+- canonical `routes/task/task_routes.py`, compatibility shim `routes/task_routes.py`, `src/task_scheduler.py`, `src/task_endpoint.py`, `src/event_bus.py`, and `src/interactive_gate.py`;
+- shared privileged task-action policy in `src/task_action_policy.py`;
+- `routes/assistant_routes.py`;
+- canonical `routes/note/note_routes.py`, compatibility shim
+  `routes/note_routes.py`, `src/builtin_actions.py`, and `src/action_intents.py`;
+- agent/tool call sites in `src/tool_index.py` and `src/tool_implementations.py`;
+- scoped Codex wrappers in `routes/codex_routes.py`;
+- database models `CalendarCal`, `CalendarEvent`, `ScheduledTask`, `TaskRun`, `Note`, and `CrewMember`;
+- direct DB CLIs `scripts/odysseus-calendar`, `scripts/odysseus-notes`, and `scripts/odysseus-tasks`;
+- frontend modules `static/js/calendar.js`, `static/js/calendar/*`, `static/js/tasks.js`, `static/js/notes.js`, and `static/js/assistant.js`;
+- tests covering calendar routes/utilities, CalDAV, recurrence, timezone handling, scheduler behavior, task webhooks, notes CLI/tool behavior, and task CLI behavior.
+
+## Calendar
+
+`routes/calendar_routes.py` owns `/api/calendar` behavior: config, multi-account CalDAV CRUD, connection test, sync, local calendar CRUD, event CRUD, recurrence expansion, ICS import/export, quick parse, and user timezone offset handling.
+
+`src.caldav_sync` owns CalDAV fetch/sync. `src.caldav_writeback` owns pushing local changes back to remote calendars. Calendar routes request those behaviors; they do not own CalDAV protocol details.
+
+Runtime behavior:
+
+- local default calendars are created lazily per owner with stable UUID5 candidates. Default creation remains inside the caller's transaction so a failed event write cannot leave an orphaned calendar; SQLite serializes the absent-row check with `BEGIN IMMEDIATE`, other backends recover insert races inside a savepoint, and renamed-owner ID collisions advance through deterministic slots. List-only callers explicitly commit the lazy default.
+- route-level no-login calendar access normalizes empty owner values to `ODYSSEUS_FALLBACK_OWNER` or `owner@localhost`, so route-created calendar rows do not use the empty string as their storage owner;
+- CalDAV account config lives in per-user prefs as `caldav_accounts`, with the legacy `/api/calendar/config` route reading/upserting the first account;
+- recurring rules are expanded server-side, including compound recurrence IDs;
+- RRULE expansion is capped and marks truncated responses;
+- event datetimes preserve UTC/local metadata through `CalendarEvent.is_utc` where supported;
+- CalDAV pull uses a bounded sync window, scopes existing UID lookups to the synced calendar, stamps account ids and remote metadata on local calendars, maps Google principal URLs to event collections, preserves locally-created or writeback-pending events that are not yet remote-owned, and deletes stale in-window remote events only when remote object parsing did not fail;
+- CalDAV writeback stores `remote_href`/`remote_etag`, clears `caldav_sync_pending` only after successful remote writes, and leaves create/update/delete pending markers for retry on failure;
+- pull and writeback paths always close their `DAVClient`, including discovery,
+  database, and remote-write failure paths;
+- sync direction can be pull, push, or both, and pending local writeback rows are included even before remote href metadata exists;
+- ICS import is per-owner, capped, creates fresh local IDs in the target import calendar, and preserves zero-duration events as visible imported rows rather than dropping them as empty ranges;
+- writeback is best-effort and local SQLite remains source of truth when remote writes fail.
+
+Calendar credentials are encrypted at rest and are not returned to clients. CalDAV URL validation rejects unsafe schemes, credentials, fragments, localhost names, bad ports, unsafe IP literals, and hostnames resolving to disallowed addresses, with `ODYSSEUS_ALLOW_PRIVATE_CALDAV=1` as the explicit private-IP escape hatch. CalDAV sync/writeback clients disable redirects so credentials are not followed to another origin. The connection-test client keeps proxy/environment trust disabled but explicitly loads an operator `SSL_CERT_FILE` or `REQUESTS_CA_BUNDLE` when the file exists so private/self-signed deployments use the same CA trust intent as real sync.
+
+## Tasks And Assistant Runs
+
+`src.task_scheduler.TaskScheduler` owns scheduled task execution, next-run computation, strict single-slot execution, queued/running cleanup at startup, overdue next-run advancement, webhook-triggered tasks, notifications, run records, chained tasks, and event-triggered actions.
+
+Cookbook serve scheduling crosses this domain. The Cookbook UI creates `cookbook_serve` scheduled tasks, can mirror them as Cookbook calendar events with `cookbook_event_uid`, and task deletion cleans up the linked event when present, falling back to exact-summary matching for legacy events without a stored UID. Cookbook command execution/lifecycle details stay in `cookbook-hwfit.md`.
+
+`routes.task.task_routes` owns task CRUD, status, manual run/stop/cancel, pause/resume, owner-scoped run/activity history, metadata, onboarding defaults, cache clearing, parse endpoints, and webhook-token regeneration. `app.py` imports the canonical package path; `routes/task_routes.py` replaces its module entry with the canonical module for legacy import and monkeypatch compatibility. Chained-task `then_task_id` values are validated as same-owner relationships on create/update, and scheduler execution also rejects cross-owner or cyclic chains.
+
+Task webhook paths are auth-exempt at the app middleware layer only for `/api/tasks/{task_id}/webhook/{token}`. The route still validates active task state plus task-specific webhook token before dispatch.
+
+Task runtime behavior:
+
+- task runs move through queued/running/success/error/skipped/aborted states;
+- scheduler/background execution can wait for `src.interactive_gate` to report a quiet foreground window, and running background work can use browser heartbeat/chat-stream activity as a cancellation/defer signal where implemented;
+- output targets include chat sessions, notifications, email, and MCP delivery paths;
+- LLM and research tasks can carry a built-in `character_id` persona prompt that the scheduler prepends at execution time;
+- task-created chat sessions can be foldered under `Tasks`, and startup migration backfills task/research folders for legacy sessions;
+- event-bus triggers persist counters and `next_run` before scheduler handoff;
+- the in-process scheduler is gated by `ODYSSEUS_INPROCESS_TASKS`, and multiple enabled app processes can double-run work.
+- action tasks with `run_local`, `run_script`, `ssh_command`, or
+  `cookbook_serve` are admin-only. `routes.task_routes` enforces this on
+  create/update/manual run and hides those actions from `/meta/actions` for
+  non-admin owners; webhook and scheduler execution pause the task and clear
+  `next_run` if an admin-only action belongs to a non-admin owner.
+- background LLM task execution uses the background workload path, and the
+  scheduler can abort/cancel active in-process task runs when foreground browser
+  activity appears.
+- `tidy_research` scans all persisted research files because broken JSON has no trustworthy owner stamp, so it runs only for admins or the explicit auth-disabled single-user operator and refuses regular/pre-setup callers before enumeration.
+
+`routes.assistant_routes.py` owns crew/assistant settings and run-status surfaces that use the scheduler. `TaskScheduler.ensure_assistant_defaults()` currently seeds the personal assistant crew member and pinned assistant session, but no longer auto-creates Morning/Midday/Evening check-in tasks. Existing crew-linked check-in tasks are still rendered and managed when present.
+
+## Notes And Reminders
+
+`routes.note.note_routes` owns notes/todos/reminders, and `app.py` imports that
+canonical path. `routes.note_routes` replaces its module entry with the
+canonical module for legacy import and monkeypatch compatibility. Notes are
+SQLAlchemy `Note` rows and can include due dates, ordering, images, repeat
+state, AI classification, source/session provenance, and agent session
+linkage.
+
+Notes CRUD/reorder/reminder routes resolve the acting owner through `require_user()`: auth-enabled anonymous requests fail closed before hitting owner-scoped queries, while documented no-login/single-user modes still resolve to the compatibility owner path.
+
+Reminder policy:
+
+- "remind me at 5pm" should become a todo/note with a due date;
+- calendar event alarm/reminder UI writes reminder Notes;
+- calendar events are for scheduled time blocks, meetings, appointments, or explicit calendar requests;
+- creating a calendar event named "Reminder" does not create notification behavior.
+
+Built-in reminder/persona prompt text is mirrored server-side for reminder synthesis and scheduled task execution; frontend persona selectors are UI over that server-owned id map, not the authority.
+
+Reminder dispatch is Note-owned:
+
+- `dispatch_reminder()` owns browser, email, ntfy, generic webhook, in-app notification, optional LLM reminder text, and dedupe behavior;
+- the scheduler note scanner calls note-ping actions for backend due-note delivery with per-owner notification state, and calendar-event reminders are treated as Note-owned reminders rather than separate scheduler event pings;
+- the notes frontend has a browser-tab fallback for visible sessions;
+- calendar frontend reminder UI stores reminder records as Notes, not calendar-event notification jobs.
+
+Email/ntfy failures degrade into channel result fields rather than blocking every reminder path. ntfy and generic webhook reminder URLs run through outbound URL safety checks, with `REMINDER_WEBHOOK_BLOCK_PRIVATE_IPS` controlling whether private/LAN targets are allowed. ntfy notification titles are converted to ASCII with replacement and capped at 200 characters before entering HTTP headers. Reminder dedupe uses owner-scoped cache files under `data/`.
+
+## Agent, Codex, And CLI Surfaces
+
+`do_manage_tasks`, `do_manage_notes`, and `do_manage_calendar` own agent-side writes. `do_manage_calendar` supports batch event creation plus list range aliases (`start`, `start_time`, `start_date`, `range_start`, `from`, `dtstart`, `since`, and matching end aliases), calendar name/short-id lookup, importance/tag aliases, and reminder offsets expressed as numbers, minute/hour words, or common abbreviations such as `min`/`mins`/`hr`/`hrs`. If a model supplies a loose `query`, `date_range`, or `range` without explicit start/end datetimes, `list_events` returns an error asking the caller to resolve the range and call again instead of guessing. Event classification reads `Memory.text` for personal context before LLM classification. `src.tool_index` encodes the reminder policy that notes/todos own reminders while calendar events own time blocks.
+
+Agent native tool owner handling is not uniform today. `do_manage_tasks()` filters lists only when `owner` is truthy and creates tasks with the passed owner, so `owner=None` can create legacy/null-owner tasks. For authenticated/non-empty owners, edit/delete/pause/resume/run require an exact stored owner match and reject both cross-owner and null-owner rows; `owner=None` retains single-user compatibility. `do_manage_notes()` list/query behavior distinguishes `None` from `""`, with `None` acting as broader single-user compatibility while `""` filters to empty-owner rows in some paths. `do_manage_calendar()` query helpers filter only when owner is not `None`, while calendar creation routes through the calendar fallback owner for default calendars. These are compatibility behaviors, not a cross-user sharing model.
+
+Note and calendar route/tool writers owner-reserve any canonical internal upload
+references in content, checklist/color/image fields, descriptions, and
+locations before their database writes. Missing or wrong-owner uploads fail the
+write instead of creating a dangling durable reference; reservations serialize
+with upload cleanup.
+
+Chat forwards browser timezone offset and IANA timezone name so natural-language note/calendar tools can anchor dates to the user clock. A valid IANA zone wins over the fixed offset for current-time/DST reasoning; invalid or absent names fall back to the offset and then server-local/UTC compatibility behavior. Chat can auto-promote note/calendar/reminder intents to agent mode.
+
+Codex todo/calendar wrappers enforce bearer-token owner and `todos:*` or `calendar:*` scopes, then delegate to note/calendar behavior as the token owner. Normal calendar/task/note routes are current-user/cookie routes and should not be treated as scoped bearer-token APIs unless they explicitly use token owner/scope policy.
+
+Direct DB CLIs are local compatibility tools. They bypass HTTP route behavior, CalDAV writeback, and some owner/timezone parsing policy.
+
+## Event Bus
+
+`src.event_bus` owns event-triggered task counters and scheduler handoff. Current emitters include chat/session/document/memory/research/email/skill paths. Ownerless events resolve to a primary configured user instead of broadcasting to every owner.
+
+The current event bus is not a calendar-event emitter despite the adjacent calendar/task/reminder domain.
+
+## Timezone And Date Semantics
+
+- calendar events store offset-aware input as UTC/naive fields plus `is_utc`;
+- note `due_date` uses ISO-like strings interpreted through note/tool parsers;
+- chat forwards browser UTC offset into `routes.calendar_routes` request-local state for natural-language date anchoring in calendar/note tool parsing;
+- generic scheduled task clock times are stored as UTC values after local conversion;
+- assistant check-ins can use an IANA timezone on `CrewMember`, with UTC fallback.
+
+Dateutil fallbacks strip timezone-aware parser results back to the naive-UTC contract before recurrence/window comparisons. Calendar agent list tools accept current range aliases implemented by `src.tool_implementations`, and equal/same-day start/end ranges are normalized to a one-day window instead of silently returning no rows.
+
+Natural-language parsers prefer time-first interpretations for short reminder/event phrases where the user supplies a clock time before a date phrase.
+
+Calendar frontend week-start preference is browser-local (`cal-week-start`) with Monday/Sunday controls; it is not persisted as a server preference.
+
+Natural-language date parsing and timezone behavior are compatibility-sensitive and need route/tool/frontend regression coverage when changed. Request-local timezone context is ephemeral and must not be persisted as user state. A valid browser IANA timezone is authoritative over a possibly stale or wrong-sign fixed offset because it carries daylight-saving rules.
+
+## Degraded And Optional Behavior
+
+- CalDAV sync no-ops with shaped errors when unconfigured, invalid, offline, or missing the optional `caldav` dependency.
+- CalDAV writeback failures are non-fatal to local calendar writes and are mostly visible through logs.
+- Missing or invalid `croniter` rejects cron schedules or yields no next run.
+- Missing timezone support falls back to UTC or legacy behavior.
+- ICS import depends on `icalendar`; missing dependency can fail before route-shaped error handling today.
+- Notes reminders can still use local browser fallback when backend email/ntfy channels fail.
+- App backup import/export does not currently include calendar events, scheduled tasks, task runs, or notes; calendar ICS import/export is separate and calendar-only.
+
+## Security And Provenance
+
+Calendar, task, note, and assistant routes are owner-scoped for normal users. Legacy null-owner behavior is compatibility-sensitive and should not silently grant authenticated owners broad mutation rights.
+
+Because auth-disabled chat owners can arrive as `None`, tool-created rows may not use the same owner value as route-created rows. Multi-user or owner-model changes must audit both route and agent paths.
+
+Task creation/update/manual run/webhook/scheduler execution blocks shell-like and Cookbook serve action types for non-admin users through `src.task_action_policy`, and tool security blocks privileged task/calendar tools for non-admin use. Assistant defaults reject synthetic owners such as `api` and `internal-tool`.
+
+Note routes store caller-provided `source`, `session_id`, `image_url`, and agent-session provenance. Canonical internal upload references in persisted note/calendar fields are owner-reserved before writes, and upload-backed bytes remain protected when fetched through upload routes. Arbitrary non-upload image/provenance URLs are not otherwise normalized or validated by note storage.
+
+## Testing Coverage
+
+Existing coverage is strongest around CalDAV URL hardening/writeback, client cleanup and operator CA handling, bidirectional/pending CalDAV sync markers, CalDAV UID calendar scoping, calendar recurrence/timezone helpers, owner-scoped calendar basics, exact-owner task-tool mutations, scheduler restart/cancel/next-run behavior, webhook auth-exemption source shape, canonical/legacy note-module identity, note-route unauthenticated fail-closed behavior, note/calendar attachment reservations, notes CLI/tool due-date behavior, calendar reminder abbreviation parsing, task CLI preview, task persona fields, and same-owner chained task validation.
+
+Route-level coverage is thinner for full calendar route behavior, task CRUD/security/run controls, live webhook token dispatch, notes owner CRUD/reminder delivery, assistant defaults/run status, event-bus triggers, Codex todo/calendar scopes, and frontend panel wiring.
+
+## Current Gaps
+
+- CardDAV still needs URL hardening parity with CalDAV; CalDAV now resolves hostnames during validation and revalidates writeback URLs.
+- `do_manage_notes()` should match HTTP note-route owner behavior for legacy null-owner notes.
+- Auth-disabled agent tools can produce or read broader owner scopes than route handlers because they receive `owner=None`; tasks, notes, and calendar need aligned policy/tests.
+- Task webhook tests should keep exercising live route token behavior and
+  admin-only action blocking, not only middleware/source strings.
+- Reminder delivery needs tests across frontend `/fire-reminder`, backend `dispatch_reminder()`, scheduler note pings, channel degradation, and dedupe.
+- Codex todo/calendar scope and owner mapping needs dedicated regression coverage.
+- Direct DB CLIs need either documented route-bypassing support status or shared helpers to avoid owner/timezone/writeback drift.
+- `scripts/odysseus-webhook` builds the live `/api/tasks/{task_id}/webhook/{token}` path with percent-encoded path segments; its direct DB token rotation/revocation behavior remains a local compatibility surface.
+- Assistant default documentation/code comments still mention check-ins that are no longer auto-seeded.
+- App backup import/export does not cover the calendar/task/note rows described by this spec.

+# Chat
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers current chat behavior in:
+
+- `routes/chat_routes.py` and `routes/chat_helpers.py`;
+- `routes/session_routes.py` and canonical `routes/history/history_routes.py`,
+  with `routes/history_routes.py` as a compatibility shim;
+- `src/chat_helpers.py`;
+- `src/agent_runs.py`;
+- `src/chat_handler.py` and `src/chat_processor.py`;
+- `core/session_manager.py` and `core/models.py`;
+- `src/attachment_refs.py` and `src/upload_handler.py` for durable attachment
+  references and write reservations;
+- `src/context_budget.py`, `src/context_compactor.py`, and `src/topic_analyzer.py`;
+- `src/foreground_model_routing.py`, `src/tool_approval_scopes.py`, `src/tool_approvals.py`, and `src/tool_capabilities.py`;
+- `routes/workspace_routes.py` for workspace selection support;
+- frontend modules `static/js/chat.js`, `static/js/chatStream.js`, `static/js/chatRenderer.js`, `static/js/sessions.js`, `static/js/search-chat.js`, `static/js/compare/stream.js`, `static/js/workspace.js`, `static/js/composerArrowUpRecall.js`, `static/js/streamingSegmenter.js`, `static/js/group.js`, and `static/js/notes.js`;
+- integration points with uploads, documents, compare, research, agent tools, memory, RAG, search, and model endpoints.
+
+## Session Ownership
+
+`core.session_manager.SessionManager` owns session persistence and message writes. `routes/session_routes.py` owns session list/create/update/archive/delete/folder/importance behavior for the sidebar. `routes.history.history_routes` owns history/topic surfaces, with `routes/history_routes.py` kept as a compatibility shim.
+
+`core.models.Session` and `ChatMessage` are pure data containers. They do not own persistence; `Session.add_message()` delegates to the configured session manager when present.
+
+Startup session discovery selects non-archived sessions by the existence of persisted `ChatMessage` rows rather than trusting the denormalized `Session.message_count`. It computes authoritative counts only for the bounded discovery set, then keeps full message hydration lazy.
+
+## Streaming
+
+`routes/chat_routes.py` owns `/api/chat`, `/api/chat_stream`, detached stream resume/stop/status, injected context, chat-message search, and rewrite routes. Streaming is the main UI path.
+
+`static/js/chat.js` owns send/abort/continue UI state, the main fetch/read loop, SSE parsing, rendering dispatch, workspace form wiring, and background/resumable stream tracking. `static/js/chatStream.js` owns UI-control event handling and stream/research notification helpers. `static/js/sessions.js` polls server stream status after refresh or session switch. `static/js/composerArrowUpRecall.js` owns prompt recall from the composer when the caret is at the top of an empty input.
+
+Runtime behavior:
+
+- the `/api/chat*` prefix is exempt from the global request hard timeout;
+- browser chat sends `X-Tz-Offset` and an IANA timezone name; request-local helpers prefer a valid IANA zone for DST-aware current-time reasoning, then fall back to the fixed offset;
+- browser chat can send a selected workspace path; route code only resolves it for admin/single-user flows, validates it as an existing directory, and forwards it so agent file/shell tools are confined by `src.tool_execution`;
+- stream callbacks can outlive a deleted session, so persistence must fail closed instead of recreating orphan messages;
+- message metadata carries timestamps, metrics, tool events, sources, hidden
+  thinking/reasoning text when providers expose it separately, context-trim
+  metrics, structured attachment references, and related UI state;
+- metadata preserves requested and actual reply models and endpoints, per-round route transitions, and answering-route cost attribution; stable session ids remain available so prompt/sequence-memory and KV-cache paths can address the same conversation consistently;
+- multimodal content can be a list of content blocks for the live provider call,
+  while persistence collapses raw media into readable text and stable
+  attachment-reference lines;
+- agent streams forward explicit round-cap, tool-budget, repeated-tool-loop,
+  and intent-without-action guard events so the frontend can distinguish a
+  controlled stop from a stalled response.
+
+`src.agent_runs` owns detached in-memory stream runs, replay buffers, replacement cancellation, resume subscribers, explicit stop, and terminal-buffer eviction. Closing the SSE connection does not necessarily stop generation. `static/js/chat.js` can live-resume a still-running detached stream through `/api/chat/resume/{session_id}`; rich responses reload from DB for canonical rendering. Detached runs are process-local and do not survive server restart.
+
+Provider adapters live below chat in `src.llm_core`. Chat consumes normalized SSE output, fallback/error events, reasoning/tool deltas, and metrics. Foreground chat is strict to the selected route by default. Only the selected owner can opt in through `foreground_fallback_enabled` plus ordered `foreground_model_fallbacks`; the retired `default_model_fallbacks` key is ignored. Eligible pre-content availability failures can advance through at most ten owner-visible exact model candidates, while missing configuration/endpoints, provider/schema errors, clean empty completions, and post-content failures remain on the selected route and surface an error. Once a route produces substantive text/reasoning or a tool call it is pinned as the answering route.
+
+Fallback candidates receive route-neutral context shaping. Only compaction performed for the answering route is persisted. Chat and agent metadata record requested/actual model and endpoint identity, round-by-round route transitions, and costs against the route that actually answered; the browser renders same-model endpoint changes as well as model changes.
+
+## Context Preface
+
+`routes.chat_helpers.build_chat_context()` owns the shared route pipeline: preset extraction, preprocessing, user-message persistence, incognito/no-memory/RAG/skills flags, prefetched compare search, YouTube transcript context, research-spinoff grounding, model normalization, and compaction.
+
+`src.chat_processor.ChatProcessor.build_context_preface()` owns source preface construction. It can add memory, RAG, web search, URL page content, and skills index context before the model call.
+
+Chat preface enhances the model's context. It must not rewrite the user message or force literal-vs-fetch interpretation before the model sees the request. See [context-building.md](context-building.md).
+
+Chat-owned external context must enter the model through `untrusted_context_message()` unless a different treatment is explicitly documented. This includes memory, RAG, web search, URL fetches, prefetched search context, YouTube transcripts, research injection, and manual context injection.
+
+## Modes And Handoffs
+
+Chat can dispatch to normal LLM calls, agent mode, research mode, or compare-related flows. Session mode is stored on `sessions.mode`.
+
+Legacy plan-mode backend plumbing still exists below chat, but `routes/chat_routes.py` currently forces browser/form `plan_mode` input off and the old visible plan window frontend module is not part of the current SPA. Treat plan-mode changes as compatibility work unless the UI contract is intentionally reintroduced.
+
+Current call sites include:
+
+- chat/research dispatch in `routes/chat_routes.py`;
+- agent execution in `src/agent_loop.py`;
+- deep research orchestration in `src/research_handler.py`;
+- compare entry points in canonical `routes/compare/compare_routes.py` and frontend compare modules.
+
+Agent-mode tool access is gated in layers. Chat route toggles and privileges
+build a disabled-tool set; incognito and compare mode remove persistence-heavy
+or UI-breaking tools; `src.action_intents.message_needs_tools()` provides
+conservative regex auto-escalation hints; `src.agent_loop`,
+`src.tool_security`, `src.tool_execution`, and internal loopback validation
+remain server-side enforcement owners.
+
+`allow_bash` and `allow_web_search` can be read from the JSON request body for browser chat posts that do not submit traditional form fields.
+
+Web search tools are per-turn explicit opt-in. Either `allow_web_search=true`
+or `use_web=true` can enable `web_search`/`web_fetch`, but an explicit
+`allow_web_search=false` wins over `use_web=true` and keeps those tools
+disabled. Explicit latest-turn web-search intent can still auto-escalate into
+agent mode and narrows the available tool set toward `web_search`/`web_fetch`,
+but it no longer re-enables web tools after an explicit denial or global
+disable.
+
+Guide-only/no-tools requests build an effective tool policy before preprocessing and agent dispatch. That policy suppresses tool-backed preprocessing/background extraction/research, disables schemas and MCP for the turn, and is still enforced by `src.tool_execution` if a model emits a tool call anyway.
+
+When route context is trimmed without full compaction, chat emits a
+`context_trimmed` SSE event and carries before/after message/token counts into
+metrics. Provider reasoning/thinking deltas are streamed for live UI handling
+but kept out of the visible saved assistant content and stored in metadata when
+available.
+
+## Attachments
+
+`src.chat_handler.ChatHandler.preprocess_message()` owns owner-scoped upload-id resolution, attachment metadata, YouTube transcript/comment preprocessing, image/VL behavior, and enhanced text used by chat. `src.document_processor.build_user_content()` owns conversion of uploaded/chat-attached files into model-ready text or multimodal blocks. `src.attachment_refs` owns persisted text/reference normalization, and `SessionManager` owner-reserves attachment ids before appending or replacing durable message rows. `static/js/fileHandler.js` owns frontend pending-file state.
+
+Attachment-only sends are valid. Missing or unauthorized ids are skipped during preprocessing, while a missing/wrong-owner durable reference aborts a message/history replacement before existing transcript rows are removed. Upload failures keep pending files for retry, unsupported media can degrade to text markers, optional Office/PDF/VL dependencies can emit extraction banners, Office attachments can create markdown documents when extracted server-side, and fillable-PDF auto-document failures fall back to normal PDF extraction. `chat_messages.content` and FTS do not retain provider data URLs; structured references stay in metadata for reloads. Chat does not own upload bytes or durable document storage; it requests document/upload behavior from those subsystems.
+
+Frontend chat distinguishes normal resend from regenerate-from-here: normal resend appends a fresh user copy and carries upload IDs where available, while regeneration truncates from the selected point. AI-message delete prompts before removing the AI response plus preceding user turn. Desktop Enter submits; mobile Enter inserts a newline unless another platform-specific send control is used.
+
+Native document tool outputs can open or refresh the document editor from
+tool-result metadata, so the UI can recover if a later `doc_update` stream event
+is missed. The chat renderer also hides raw/incomplete leaked tool JSON and
+document fences from normal transcript text.
+
+When untrusted external/workspace content has entered the agent context, high-impact tool calls pause as exact approval cards instead of executing. The browser can allow the rest of the interrupted task, allow this chat session, or deny; it submits only the opaque id/decision with an empty control-plane message and does not mutate the composer. The server restores the sealed first action plus private selected tools/query, revalidates policy and document freshness, consumes the first action, and resumes without persisting a synthetic user message. Task scope ends with that resumed run. Chat scope persists the resolved card and marks later context only for that exact session; forks do not inherit it. A normal message retires an unresolved card while preserving taint.
+
+## Security And Provenance
+
+`/api/chat` and `/api/chat_stream` verify session ownership before loading the session. Chat privilege gates enforce allowed models and daily message caps before LLM work. Active document injection, session auth/header recovery, endpoint repair, upload-id resolution and reservation, memory/RAG retrieval, and post-response work must stay owner-scoped.
+
+The scoped API-token chat surface is `/api/v1/chat`. Browser chat routes can receive bearer-auth state from middleware, but route code must not assume `"api"` is a durable owner; API-token support requires explicit scope checks and token-owner attribution.
+
+Incognito disables memory, skill, and chat-history tools and skips assistant DB persistence, but current user-message persistence and later cleanup are not a strict no-write guarantee. Treat incognito changes as security-sensitive until that contract is clarified.
+
+## Search Boundary
+
+`GET /api/search` in `routes/chat_routes.py` is chat-message search for the UI and slash commands. Web search routes are owned by canonical `routes/search/search_routes.py`; chat and agent web context call through `src.search`, compatibility shims, and search content fetchers. Do not confuse chat-history search with external web retrieval.
+
+## Degraded And Compatibility Behavior
+
+- Missing ChromaDB, embeddings, memory vectors, RAG managers, or skills indexes should remove injected context or fall back to keyword/text behavior without failing chat.
+- Direct URL prefetch failures become compact untrusted context stating that the page was not read, with only transport-owned HTTP/size/rate-limit status where recognized; raw URLs, exception text, and response-controlled diagnostics are not echoed into logs or model context.
+- Sessions hydrate legacy string headers and multimodal JSON-array content, export text/HTML/Markdown after flattening non-string blocks, can lazy-load from DB when cached state is empty, and preserve old history/index delete behavior where needed.
+- Initial shell/session loading is non-blocking: the sidebar can render before a selected transcript is hydrated, and full transcript hydration is deferred until display or a model send requires it.
+- Chat repairs empty selected models and orphaned endpoint references before provider calls when possible.
+- Deleted-session stream writes fail closed.
+- Docker/native endpoint differences are owned by runtime/model setup, but chat sessions depend on the saved endpoint URLs and headers.
+- Copying a response from the UI copies the displayed answer text and omits hidden reasoning/thinking segments.
+
+## Current Gaps
+
+- Chat, agent, research, and compare orchestration still meet in a large route file.
+- Context preface behavior is spread across `routes/chat_helpers.py`, `src/chat_processor.py`, route injections, and agent/tool paths.
+- Detached stream lifecycle spans `routes/chat_routes.py`, `src/agent_runs.py`, `static/js/chat.js`, `static/js/sessions.js`, and non-chat callers.
+- Some frontend stream state is still global/module-level in `static/js/chat.js` and needs careful session isolation when adding background or resumable flows.
+- Chat lacks route-level SSE regression tests for `/api/chat_stream`, live resume/stop/status, mode handoff, persistence metadata, partial-save behavior, attachment/doc-update events, browser timezone offset/workspace handling, and literal URL context intent.
+- Bearer-token behavior on browser chat routes and incognito persistence need explicit contract decisions and regression coverage.

+# Compare
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers model A/B comparison behavior in:
+
+- canonical `routes/compare/compare_routes.py`, with `routes/compare_routes.py` as a compatibility shim;
+- `routes/session_routes.py`;
+- `routes/chat_routes.py` and `routes/chat_helpers.py`;
+- `routes/model_routes.py`;
+- canonical `routes/search/search_routes.py`, with `routes/search_routes.py` as a compatibility shim;
+- `core/database.py` model `Comparison`;
+- `src/llm_core.py` and `src/endpoint_resolver.py`;
+- frontend modules under `static/js/compare/`;
+- `static/js/chat.js`, `static/js/sessions.js`, `static/js/models.js`, and `static/js/slashCommands.js`;
+- `tests/test_compare_*` and focused blind-compare redaction tests.
+
+## Runtime Behavior
+
+The active text compare UI creates ordinary `[CMP]` sessions through `/api/session`, then streams each pane through `/api/chat_stream` with `compare_mode=true`. Search compare is a separate branch: it can query `/api/search/query` directly and its synthesis sessions use ordinary chat streaming without `compare_mode=true`. `static/js/compare/index.js` owns compare orchestration, session creation, execution order, search-mode branching, and export actions. `static/js/compare/panes.js` owns pane add/remove/swap/reroll lifecycle. `static/js/compare/stream.js` owns pane streaming and event rendering.
+
+`routes/compare/compare_routes.py` owns the `/api/compare` HTTP surface for alternate/legacy start/vote/history/delete behavior and the active `/api/compare/record` vote-summary endpoint. The top-level module is a compatibility alias. Legacy `/api/compare/start` uses neutral helper-session names and withholds model identities/mapping from the start response while blind mode is active. It does not own provider-specific payload behavior.
+
+Current call sites include:
+
+- `/api/session` compare session creation and cleanup in compare frontend modules;
+- `/api/chat_stream` pane execution through chat routes and detached stream infrastructure, streamed directly into panes so upstream generation stops promptly when panes are stopped;
+- `/api/models` and probe routes for model/endpoint selection;
+- search-provider compare mode through `routes/search/search_routes.py`;
+- `/api/compare/record` as a fire-and-forget backend vote summary, while active scoreboard state is localStorage-backed.
+
+`Comparison` rows currently persist vote/history metadata: prompt, first model identifiers, winner, blind flag, optional N-model JSON in `blind_mapping`, vote timestamp, and owner. Response and metric columns exist in the schema but are not populated by the active compare UI flow. Compare history must be owner-scoped.
+
+Frontend compare behavior is split by responsibility:
+
+- `state.js` owns local compare state;
+- `selector.js`, `models.js`, and `probe.js` own endpoint/model selection and probe UI;
+- `panes.js` and `stream.js` own paired response rendering;
+- `vote.js` and `scoreboard.js` own voting and history display.
+
+Compare panes can receive `ask_user` or tool-approval controls from the shared chat stream. `static/js/compare/stream.js` routes those controls into the main chat renderer/control plane, pauses pane completion/autograding while a choice is pending, and can resume the pane after the user decision; compare orchestration keeps its busy state until those continuations settle.
+
+Mobile compare layout collapses multi-pane grids to a single column so panes
+remain readable on narrow screens while the desktop grid still uses the
+selected column count.
+
+## Ownership Boundaries
+
+Compare owns paired evaluation flow and pane state. Chat routes own the actual stream execution path for compare panes. LLM provider code owns model-call mechanics. Session/model routes own endpoint-id resolution, owner-filtered endpoint/model visibility, header copying, and deleted-endpoint failures.
+
+`compare_mode` in chat strips compare-breaking tools, disables document tools for `[CMP]` sessions, skips some research clarification, and suppresses memory, skill, and webhook side effects after pane responses.
+
+Compare frontend code is part of the app DOM security surface. Current stream/search rendering sanitizes probe labels and tool labels, constrains search-result links to HTTP(S), uses safe generated-image display sources, and opens compare export/image popups with opener isolation.
+
+## Policy Notes
+
+- Current blind compare is UI/API masking until vote/reveal, not a full confidentiality boundary. `[CMP]` session names and session-list model fields are redacted for helper sessions, and legacy `/api/compare/start` withholds model identity/mapping while blind. Client-side selected model state and privileged/local inspection can still expose identity.
+- Compare endpoint lists and secondary endpoint lookups use owner filtering so users see and resolve only shared or owned endpoints.
+- Non-admin compare session creation must use registered owner-visible endpoints; compare must not allow arbitrary raw endpoint URLs to bypass session-route endpoint policy.
+- Prefetched search, URL, RAG, and research context entering compare panes must use the untrusted-context wrapper.
+- Compare panes use chat's foreground routing contract: selected routes are strict unless that owner explicitly enabled ordered foreground fallbacks. Verify each pane still reaches its intended route and that any opt-in route transition or error is visible.
+
+## Degraded And Compatibility Behavior
+
+- Missing/offline endpoints are surfaced by model/session routes; chat can clear orphaned endpoint references and recover empty models when possible.
+- Compare streams inherit chat's opt-in, eligible-pre-output-only foreground fallback and provider-normalized SSE events, but compare frontend handling for errors and model/endpoint route transitions is thinner than chat's stream path.
+- Shared legacy `ModelEndpoint.owner == NULL` rows remain visible through owner filters. Legacy `Comparison.owner == NULL` rows are not treated as shared for authenticated vote/delete/history flows.
+- `/api/compare/start` and `/{comp_id}/vote` remain implemented but are not the active frontend path.
+
+## Current Gaps
+
+- Blind mode is not a confidentiality boundary; client/local state can still expose model identity before vote.
+- `/api/compare/start` accepts raw endpoint URLs and can diverge from `/api/session` endpoint-owner/raw-endpoint policy.
+- `src/agent_loop.py` advertises stale compare app API endpoints.
+- Compare streaming and chat streaming are separate frontend paths but share model/provider infrastructure; regressions can happen when provider event shape changes.
+- Compare frontend needs explicit fallback/error event handling parity with chat streaming.
+- Compare tests cover endpoint owner helper behavior, blind compare redaction, ask-user/tool-approval routing, and portable JS helpers, but not full active `/api/session` pane creation, frontend pane lifecycle, or complete SSE fallback/error handling.

+# Context Building
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers model-context construction in:
+
+- `src/chat_processor.py`;
+- `src/chat_handler.py` and `src/youtube_handler.py`;
+- `routes/chat_helpers.py` and context injection in `routes/chat_routes.py`;
+- `src/agent_loop.py`;
+- `src/tool_execution.py`;
+- `src/attachment_refs.py` and uploaded-file manifest construction in
+  `routes/chat_helpers.py`;
+- `src/tool_policy.py`;
+- `src/prompt_security.py`;
+- `src/tool_capabilities.py`, `src/tool_approval_scopes.py`, and `src/tool_approvals.py`;
+- transport primitives in `src/outbound_fetch.py` plus fetch/extraction adapters in `src/search/content.py` and `services/search/content.py`;
+- search orchestration in `services/search/core.py` and the compatibility wrapper in `src/search/core.py`;
+- RAG and personal docs in `src/rag_singleton.py`, `src/rag_vector.py`, `src/rag_manager.py`, and `src/personal_docs.py`;
+- research flows in `src/deep_research.py`, `src/research_handler.py`, and `services/research/research_handler.py`;
+- memory and skills in `src/memory.py` and `services/memory/*`;
+- related policy in `THREAT_MODEL.md`.
+
+## Contract
+
+Context-building tools gather evidence. They do not own user-intent routing.
+
+Runtime rules:
+
+- if external context is available, add it as compact untrusted source data;
+- if an attempted source is unavailable and relevant, represent the unavailable state explicitly with source and reason when known;
+- preserve the user's original message for the model;
+- do not use regex preprocessing to force literal-vs-fetch intent;
+- do not disable tools or force a reply style solely because preprocessing found a URL.
+
+## Untrusted Data
+
+`src.prompt_security` owns the untrusted wrapper:
+
+- `UNTRUSTED_CONTEXT_POLICY` states global model policy;
+- `untrusted_context_message(label, content)` wraps source content as user-role data with `metadata.trusted = False`, provenance origin, and an `arm_tool_gate`/`tool_gate_untrusted` signal that defaults to arming the server-owned tool gate.
+
+Current untrusted context sources include:
+
+- fetched URLs and web search results;
+- webpage content passed into deep-research extraction;
+- YouTube transcripts/comments;
+- RAG/personal document chunks;
+- memories and skills;
+- notes and active editor documents;
+- emails and attachments;
+- tool output from external/user-controlled data.
+
+Live multimodal provider blocks can contain data URLs, but persisted and
+tool-facing context uses stable attachment references. Tool manifests carry an
+`odysseus://attachment/<id>` URI and owner-checked read policy; local paths are
+compatibility data added only after owner and root-confinement checks. Persisted
+chat context keeps readable text/reference lines rather than reinserting raw
+media bytes into later turns or search state.
+
+## URL, Search, And Tool-Derived Context
+
+Chat URL prefetch and agent `web_fetch` are different paths. Chat prefetch happens before the model call; `web_fetch` is a tool the model may choose later. Both should converge on the same intent: enrich context when content is available, represent unavailable content when it is not, and let the model interpret the user request.
+
+Search results and fetched pages are evidence. `web_search` should not force a page fetch unless its explicit contract says it does. Failed fetches should not crash chat or silently imply content was read. Canonical search content fetchers can extract readable text from HTML, `text/*`, Markdown, `.txt`, `.json`, and `.jsonl` responses and should return shaped error results for HTTP status failures. URL fetches validate every redirect hop and pin the outbound connection to a public IP resolved during validation, so context-building callers do not need a second DNS-rebinding guard.
+
+Current behavior is not yet unified:
+
+- successful chat URL prefetch is wrapped as untrusted context; failed prefetch now adds a compact untrusted statement that the page was not read, recognizes only transport-owned HTTP/size/rate-limit categories, and suppresses raw exception/response text;
+- agent `web_fetch` returns explicit URL-specific tool errors for timeout, unsupported scheme, fetch failure, or no readable text;
+- comprehensive search reports provider-chain failures, but individual page-fetch failures can be logged and omitted;
+- YouTube fetching is owned by `ChatHandler`/`youtube_handler`, while `routes.chat_helpers` only wraps the resulting transcript/comment strings.
+
+`src.outbound_fetch` owns reusable synchronous public-URL classification, per-hop DNS resolution/pinning, redirect handling, and body budgets. `services/search/core.py` owns `comprehensive_web_search()` orchestration. `services.search.content` owns content extraction and adapts the shared transport; `src/search/core.py` and `src/search/content.py` preserve compatibility imports without a second implementation.
+
+## Tool Result Envelope
+
+`src.tool_execution` executes and formats tools. Tool output caps live in `src.constants` and are re-exported through older facades; shared native-tool truncation lives in `src.tool_utils`. `src.agent_loop._append_tool_results()` owns model re-entry: native tool calls return as provider-style `role: "tool"` messages with untrusted metadata, while fenced-tool results use the untrusted wrapper. Classification considers both the requested tool and the result payload, so remote or stored model-visible content can arm the session gate even on a failed tool status.
+
+Taint is server-owned continuation state, not a model instruction. After untrusted external/workspace context, low-impact reads can continue, but high-impact, unknown, and arbitrary MCP actions become proposals that produce an exact approval card. The server seals the exact first action plus private continuation tool/query state; document actions also bind the current document version and digest. A chat decision can allow the resumed task or persist a grant for later turns in that exact chat, while non-chat callers remain single-action. Blocked/approval placeholders and content-free failures do not recursively arm the gate.
+
+Context budgeting uses known model context windows when available. `src.context_budget` treats the default 6000-token value as an automatic sentinel, scales to a capped fraction of known context length for non-explicit budgets, and leaves unknown windows on conservative defaults.
+
+Side-effect enforcement lives outside context building. Chat route disabled-tool policy, `src.tool_security`, `src.tool_execution`, and `do_app_api()` block unsafe tool execution; prompt wording alone is not the authority.
+
+Guide-only/no-tools policy can suppress context acquisition before the model call. `src.tool_policy` feeds chat route preprocessing and agent-loop assembly so tool-backed search/research/memory/RAG/skills/local-context paths are skipped when the latest user turn explicitly forbids tools.
+
+## Degraded And Optional Dependencies
+
+- ChromaDB, HTTP embeddings, and FastEmbed are installed/expected in normal setups but must degrade cleanly when a service, package, or embedding backend is unavailable.
+- `src.rag_singleton.get_rag_manager()` owns RAG startup retry throttling; `src.rag_vector.VectorRAG` is the live owner-filtered path; `src.rag_manager.RAGManager` is compatibility/backward-compat behavior.
+- Memory-vector and tool-index retrieval can fall back to keyword/text behavior when vector stores or embeddings fail.
+- Docker compose and native installs use different Chroma host defaults; model endpoint loopback rewriting is owned by model/runtime specs.
+
+## Current Call Sites Include
+
+- `ChatProcessor.build_context_preface()` for memory, RAG, web search, URL content, and skills index;
+- `ChatHandler.preprocess_message()` and the canonical `services.youtube.youtube_handler` import path for YouTube fetch/format, then `routes/chat_helpers.py` for wrapping prefetched search/Youtube context;
+- `routes/chat_routes.py` research context injection;
+- `src.agent_loop` for active editor document, skill context, and tool-result reinsertion;
+- uploaded-file manifest/reference context for agent tools and later chat turns;
+- `src.tool_execution` for `web_search`, `web_fetch`, file, shell, MCP, and other tool outputs;
+- `src.deep_research` and research handlers for search/fetch/extract flows used by research jobs, with fetched webpage text wrapped before extraction and analyzed URLs tracked separately from source snippets.
+
+## Current Gaps
+
+- URL/search context result shape is not unified across chat prefetch, agent tools, and research.
+- Failed fetch representation remains inconsistent outside direct chat URL prefetch, especially in comprehensive search and research aggregation.
+- Tool/context wording is spread across schema, prompt, and retrieval surfaces.
+- Source-specific wrapping and unavailable-state behavior still needs broader focused coverage for literal URL intent, research, RAG/memory/skills, and YouTube; external tool results and approval continuation now have dedicated gate/taint regressions.
+- Compare pre-search context is computed but may not be submitted through the current compare stream form.

+# Cookbook And Hardware Fit
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers model setup/serving and hardware fit in:
+
+- app route registration in `app.py`;
+- `routes/cookbook_routes.py`;
+- `src/cookbook_serve_lifecycle.py`;
+- `src/host_docker_access.py`;
+- Cookbook package/rebuild/shell integration in `routes/shell_routes.py`;
+- `routes/cookbook_helpers.py`;
+- `routes/hwfit_routes.py`;
+- `services/hwfit/*` and `services/hwfit/data/hf_models.json`;
+- durable Cookbook state through `routes.cookbook_helpers.COOKBOOK_STATE_FILE`;
+- helper/CLI scripts `scripts/odysseus-cookbook`, `scripts/add_hwfit_models.py`, `scripts/hf_download.py`, and `scripts/diffusion_server.py`;
+- Docker overlays `docker-compose.gpu-*.yml`, `docker/gpu.*.yml`, `docker/host-docker.yml`, `scripts/check-docker-gpu.sh`, and `scripts/check-docker-amd-gpu.sh`;
+- frontend modules `static/js/cookbook*.js`, including Cookbook running, serve, download, diagnosis, progress, and HW Fit modules;
+- tests covering Cookbook helpers, routes, CLI state, package detection, frontend progress, HW Fit services, serve profiles, Docker GPU overlays, and GPU diagnostic scripts.
+
+## Current Call Sites Include
+
+- Cookbook modal and state modules in `static/js/cookbook*.js`;
+- package readiness/install and rebuild flows through `routes/shell_routes.py`;
+- direct shell exec/stream integration used by Cookbook task controls;
+- model endpoint setup and serve flows;
+- hardware-fit recommendations for model choices;
+- image-model recommendations for diffusion serving;
+- APFEL/local platform dependency paths where supported;
+- Docker GPU helper scripts and compose overlays;
+- the `odysseus-cookbook` CLI using the same Cookbook state file.
+
+## Cookbook Runtime
+
+`routes.cookbook_routes` owns model download, setup, SSH key, cached model scan, serve, GPU state, kill-pid, state sync, Hugging Face latest lookup, vLLM recipe lookup, serve diagnosis, and task-status endpoints. `src.cookbook_serve_lifecycle` bridges scheduled `cookbook_serve` tasks into serve/stop behavior; task/calendar scheduling ownership stays in `calendar-tasks-notes.md`.
+
+Access policy is split by surface:
+
+- download/setup/SSH key/cache scan/serve/GPU/kill/state/task-status are admin/internal-tool surfaces;
+- `/api/cookbook/hf-latest` is authenticated-user gated;
+- HW Fit routes are authenticated read/probe routes through normal middleware, not admin-only operations;
+- bearer API tokens do not satisfy Cookbook admin gates.
+
+Runtime behavior:
+
+- POSIX and most remote flows run detached through tmux;
+- local Windows uses detached process/log/pid behavior under `%TEMP%\\odysseus-tmux`; Python first publishes a valid Win32 fallback PID, then Git Bash may replace it with `/proc/$$/winpid` after a ready-file handoff, so PowerShell `Stop-Tree` can terminate the actual serving shell and children instead of receiving an MSYS PID. Frontend PowerShell venv activation is quoted safely and the local Git Bash runner converts a valid `Scripts\\Activate.ps1` prefix into `source <git-bash-path>/Scripts/activate` so the selected environment actually supplies the serve binary;
+- remote Windows uses PowerShell runner scripts;
+- missing `tmux`, `docker`, or serve-engine binaries return shaped errors where possible;
+- local Docker inside the Odysseus container is available only when the Docker CLI exists, `ODYSSEUS_ENABLE_HOST_DOCKER=true`, and `/var/run/docker.sock` is actually mounted as a socket; otherwise Cookbook should show the host-Docker access hint and prefer remote SSH Docker workflows;
+- model serve auto-registers LLM or image `ModelEndpoint` rows immediately, then frontend readiness probing can repair/create fallback endpoints;
+- diffusion-server serves are registered as image endpoints;
+- MLX image serves use `scripts/mlx_image_server.py`, which pins generation/edit dispatch to the model chosen at process start and ignores OpenAI-compatible per-request model selectors;
+- vLLM recipe routes fetch and cache model recipe manifests/YAML from `vllm-project/recipes`, normalize base args/env/dependencies/tool-calling/reasoning variants, and expose compatible strategy metadata for serve setup;
+- Hugging Face download/setup paths can detect and persist encrypted HF tokens for later Cookbook/agent use;
+- local and remote model paths can contain spaces or non-ASCII characters when helper validation/quoting accepts them;
+- task status handles tmux, remote Windows logs, local Windows PID/log files, HF cache completion checks, stale browser-state download guards, pip dependency-install success sentinels, exit-code wrappers, serve diagnosis snapshots, and scheduled serve lifecycle hooks;
+- scheduled serve lifecycle stop attempts only persist `status=stopped`, clear `_scheduledStopAtMs`, and delete auto-registered endpoints for sessions whose tmux/remote stop command succeeded or were already gone; failed stop attempts are logged without marking unrelated expired serves as stopped.
+
+`routes.cookbook_helpers` owns validation and command construction:
+
+- repository and model IDs;
+- local directories, SSH hosts/ports, GPU selectors, and tokens;
+- shell quoting for Bash and PowerShell;
+- pip/install fallback chains;
+- safe environment prefixes;
+- serve command validation;
+- user-shell PATH bootstrap, Git-Bash drive-path conversion, preflight, and exit-code helpers.
+
+Cookbook routes request shell/SSH behavior; they do not relax shell security.
+
+## Shell Dependencies
+
+`routes.shell_routes.py` owns Cookbook-adjacent package readiness/install, shell execution/streaming, and llama.cpp rebuild endpoints. The Cookbook UI calls these routes for dependency diagnosis, install/update actions, engine rebuilds, and tmux/reconnect/stop/kill flows. Windows uses detached log/PID wrappers where POSIX tmux is unavailable.
+
+These are admin-only code-execution surfaces and should be reviewed with Cookbook changes even though they are implemented outside `routes.cookbook_routes.py`.
+
+## State, Secrets, And Provenance
+
+Cookbook state lives under the shared data dir through the `COOKBOOK_STATE_FILE` constant, normally `data/cookbook_state.json`. Routes and the `odysseus-cookbook` CLI use the same state path.
+
+State behavior:
+
+- browser-facing state masks secrets;
+- server-side `env.hfToken` is encrypted before storage;
+- task payloads strip raw HF tokens;
+- browser local storage strips HF token values;
+- state POST has anti-wipe guards for server lists;
+- state POST rejects stale `done` download state when the latest shard/cache markers still show an incomplete download;
+- recent server-side tasks are preserved against stale browser overwrites;
+- task-status validates saved shell-bound fields before SSH/tmux commands.
+
+Cookbook auto-registered endpoints are currently shared/null-owner rows with no API key when created by backend serve registration. Browser fallback registration goes through the normal model-endpoint route. The desired ownership policy for Cookbook-created endpoints should remain explicit.
+
+HW Fit is an MIT-licensed llmfit adaptation; attribution lives in project acknowledgments/licenses.
+
+## Hardware Fit
+
+`services/hwfit/hardware.py` owns hardware detection across NVIDIA, AMD, Apple Silicon, Windows, CPU, RAM, available RAM, remote SSH, container/native probe context, and cached host detections.
+
+`services/hwfit/models.py`, `fit.py`, `profiles.py`, `image_models.py`, and
+`hf_discovery.py` own model catalog loading, normalization, API-backed dynamic
+catalog refresh, memory estimates, quantization labels, fit scoring, serve
+profile computation, image model ranking, and backend/format servability
+filtering.
+
+`routes/hwfit_routes.py` owns the HTTP surface and manual hardware override application.
+
+Runtime behavior:
+
+- hardware detection uses a cache with `fresh=true` bypass;
+- probe results include scope/container visibility metadata, and containerized no-GPU/low-RAM states can return user-facing visibility warnings with rescan/manual/copy-diagnostics actions;
+- manual hardware replacement is a what-if simulator, not additive hardware;
+- manual hardware accepts `cuda`, `rocm`, `metal`, `cpu_x86`, and `cpu_arm`
+  backends and must stay in lock-step with backend support in `fit.py`. Metal
+  simulation marks unified memory and filters toward locally servable GGUF/MLX
+  choices instead of CUDA/vLLM-only formats.
+- ignore switches can drop detected GPU/RAM before ranking;
+- homogeneous GPU grouping targets realistic multi-GPU pools;
+- image model ranking normalizes to a single-GPU fit view;
+- Metal/RDNA/backend restrictions can filter otherwise fit models.
+- Apple Silicon bandwidth estimates use chip/core-specific tables for M-series Max/Pro/Ultra variants and avoid matching non-Apple GPU names.
+- Windows and Apple/consumer-AMD paths filter toward GGUF/llama.cpp-compatible
+  choices. On multi-GPU systems, fixed GGUF target quantization that cannot be
+  served by the selected backend returns `no_fit` rather than `None`.
+
+## Platform And Degraded Behavior
+
+- Linux, Windows/PowerShell, macOS, Docker, NVIDIA, AMD, Apple Silicon, and CPU-only systems have different command paths.
+- Remote hosts are accessed through SSH helpers; Cookbook host/port/path inputs must be validated before command construction.
+- HW Fit remote host/port query values currently do not share all Cookbook route-level validation before SSH probing.
+- Missing local tools or failed installs should surface command/output/error detail where possible.
+- GPU overlays remain optional and do not break CPU-only deployments.
+- Docker GPU overlays pass host devices/env; they do not install CUDA/ROCm engines by themselves.
+- Default Docker Compose intentionally does not mount the host Docker socket. `docker/host-docker.yml` is an explicit high-trust overlay for operators who accept broad host-Docker control from inside the container.
+- NVIDIA Docker diagnostics are read-only by default, and `.env` edits/install actions require explicit flags.
+- AMD Docker diagnostics are read-only and do not mutate `.env`.
+- vLLM is rejected on unsupported Windows/macOS paths.
+- llama.cpp CPU-only and GPU fallback scripts should preserve usable CPU paths.
+- SSH probe failures, GPU driver errors, and no-GPU states should be distinguishable.
+- Remote SSH host/port validation is shared through route validators for Cookbook/HWFit paths.
+- Windows launcher/runtime Git Bash discovery includes per-user installs under `%LocalAppData%\\Programs\\Git`, and WSL/Git Bash detection shapes PATH handling for NVIDIA/remote flows.
+- macOS startup helpers start ChromaDB alongside the app path.
+- Ollama serve can auto-pick an available port, and scheduled task stop paths
+  verify stop success before persisting a stopped state.
+
+## Model Catalog And Latest Lookup
+
+HW Fit model scoring depends on bundled `services/hwfit/data/hf_models.json`,
+bundled `services/hwfit/data/mlx_community_models.json`, runtime dynamic caches
+under `DATA_DIR/hwfit/`, catalog normalization, and assumptions about model
+formats and quantization. `scripts/add_hwfit_models.py` updates the static HF
+catalog.
+
+Hugging Face latest lookup and HW Fit dynamic refresh use external Hub metadata
+and can degrade to empty, unknown-size, partial, or malformed-result behavior.
+`refresh_catalog=1` refreshes API-backed collection caches for MLX community
+and selected HF organization collections, with a 24-hour freshness guard and
+bundled JSON fallbacks when the network/cache is unavailable. HW Fit tolerates
+non-numeric `gpu_count` values from callers. Model normalization also treats
+non-string `parameter_count` and quantization fields as unknown rather than
+calling string methods and aborting the ranking pass. Catalog drift and dynamic
+latest-model metadata are separate sources of recommendation drift.
+
+## Security Policy
+
+Admin gates must stay in place for install, serve, kill, setup, state mutation, and shell-like actions. `/api/shell/exec` is an admin primitive used by Cookbook task control and must stay in this review boundary. Scheduled `cookbook_serve` tasks are admin-only action tasks; task create/update/manual run/webhook/scheduler execution must all reject or pause them for non-admin owners.
+
+Kill-pid guardrails:
+
+- admin-only;
+- PID floor;
+- signal allowlist;
+- validated remote host/port;
+- frontend confirmation for TERM/KILL cleanup.
+
+Shell-bound Cookbook inputs must pass helper validation before command construction. HF tokens, Cookbook state secrets, and endpoint API keys must remain encrypted or masked and must not be written back to clients in raw form. Host Docker socket access must stay opt-in and clearly distinguished from merely having a Docker CLI in the container.
+
+## Testing Coverage
+
+Existing coverage is strongest for helper validation/quoting, SSH host validation, pip fallback and dependency-completion regressions, cached scan scripts, serve profile computation, scheduled serve lifecycle state persistence, hardware detection/ranking across AMD/NVIDIA/macOS/manual/container modes, MLX/Metal ranking and request-model pinning, manual backend simulation, Docker GPU compose overlays, Cookbook CLI state, package detection, Windows venv/path/task helpers, non-numeric GPU counts, non-string model catalog fields, and selected frontend progress regressions.
+
+Route-level auth/security and degraded-return coverage is thinner for Cookbook admin routes, shell dependency routes, `/api/cookbook/hf-latest`, state/status edge cases, HW Fit routes, frontend JS behavior, and helper scripts such as `hf_download.py`, `add_hwfit_models.py`, and `diffusion_server.py`.
+
+## Current Gaps
+
+- Cookbook-created model endpoint ownership/shared/null-owner policy needs a deliberate decision.
+- `/api/shell/exec` and Cookbook package/rebuild routes need to remain cross-referenced with shell/admin specs because they are Cookbook-critical code-execution surfaces.
+- Cookbook route auth/security and degraded-return behavior need route-level tests.
+- `/api/cookbook/hf-latest` needs tests locking its user-authenticated access policy and failure behavior.
+- HW Fit routes need route-level tests around missing catalogs, manual overrides, `fit_only`, profiles, and image-model cases.
+- Dependency install/serve diagnosis remains split across Cookbook routes, shell routes, frontend diagnosis, optional binaries, and platform-specific scripts, even though longer serve-output tails are centralized through `routes/cookbook_output.py`.
+- Model catalog, quantization, backend, and Hugging Face metadata drift need ongoing maintenance.

+# Documents, RAG, And Uploads
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers file/document context, document storage, and vector retrieval in:
+
+- `app.py` and `src/app_initializer.py` route/manager wiring;
+- `routes/upload_routes.py`, `routes/personal_routes.py`, `routes/embedding_routes.py`, canonical `routes/document/document_routes.py` and `routes/document/document_helpers.py`, plus their top-level compatibility shims;
+- chat attachment paths in `routes/chat_routes.py`, `routes/chat_helpers.py`, `src/chat_handler.py`, and `src/chat_processor.py`;
+- `core/session_manager.py`, `src/attachment_refs.py`, `src/upload_handler.py`,
+  `src/upload_limits.py`, and the public reference contract in
+  `docs/attachments.md`;
+- `src/document_processor.py`, `src/document_actions.py`, `src/personal_docs.py`, and `src/markitdown_runtime.py`;
+- `src/rag_singleton.py`, `src/rag_vector.py`, `src/rag_manager.py`, `src/chroma_client.py`, `src/embeddings.py`, and `src/embedding_lanes.py`;
+- PDF/form helpers in `src/pdf_runtime.py`, `src/pdf_forms.py`, and `src/pdf_form_doc.py`;
+- `services/docs/service.py`;
+- document, upload, RAG, chat, email, and admin frontend callers in `static/app.js`, `static/js/chat.js`, `static/js/chatRenderer.js`, `static/js/fileHandler.js`, `static/js/document.js`, `static/js/documentLibrary.js`, `static/js/rag.js`, `static/js/admin.js`, `static/js/emailInbox.js`, and `static/js/slashCommands.js`;
+- tests covering upload, document, attachment, PDF, RAG, Chroma, MarkItDown, and embedding behavior.
+
+## Runtime Integration
+
+`app.py` registers upload, personal-doc/RAG, embedding, document, diagnostics, and Codex document routes. `src.app_initializer.initialize_managers()` creates `UploadHandler` and `PersonalDocsManager`, installs the upload handler on `SessionManager` and the shared tool helper, and startup attempts to initialize the RAG singleton. App route wiring passes that same handler to session/history, document, note, and calendar writers that can persist upload references.
+
+`src.rag_singleton.get_rag_manager()` returns the live `VectorRAG` instance when Chroma/embedding dependencies are reachable. Personal routes can retry the singleton and return explicit 503s when unavailable. Chat RAG uses the `PersonalDocsManager.rag_manager` captured during app initialization and can silently skip RAG if that manager is absent.
+
+## Uploads And Attachments
+
+`src.upload_handler.UploadHandler` owns upload IDs, safe filenames, upload metadata, owner rename rewrites, atomic `uploads.json` writes, content-type detection, and file storage under `data/uploads`. Upload IDs accept extensionless values or one sanitized alphanumeric extension.
+
+Upload-index reads track the live and `.bak` files by device, inode, size, nanosecond mtime, and ctime, then verify the combined signature after parsing. This catches same-timestamp corruption/replacement and prevents stale parsed data from being cached under a newer file identity. Non-destructive reads can recover from the backup; destructive cleanup requires a valid live index and never treats an older backup as deletion authority. Lifecycle writes can synchronize the backup so intentionally removed metadata is not resurrected.
+
+`src.upload_limits` owns central upload-size caps and environment overrides for chat attachments, gallery, transforms, memory import, personal uploads, email compose, STT audio, and ICS imports. Invalid configured limits fail fast at import so routes do not silently accept unsafe sizes. Docker installs `libmagic1` plus `python-magic` so `UploadHandler.detect_content_type()` can sniff bytes in the official image; native installs can fall back to extension/MIME guesses when `python-magic` is unavailable.
+
+`routes/upload_routes.py` owns:
+
+- `POST /api/upload`, returning uploaded file metadata;
+- reference-aware admin upload cleanup and stats;
+- `GET /api/upload/{file_id}`;
+- `GET/PUT /api/upload/{file_id}/vision` for editable OCR/vision cache;
+- thumbnail and masked owner/admin access behavior.
+
+It does not currently expose a general upload list/delete route. Download/preview responses that serve uploaded content should include `X-Content-Type-Options: nosniff` where route code owns the response so browser MIME sniffing does not widen accepted upload types.
+
+Readable/code-like upload handling includes common text/code extensions plus `.nix`; document processing renders recognized code-like text into fenced blocks with language metadata.
+
+Chat does not own attachment extraction. Runtime flow:
+
+- the frontend uploads files and submits attachment IDs;
+- `ChatHandler.preprocess_message()` resolves IDs with the session owner through `UploadHandler.resolve_upload()`, which enforces owner/admin access and no longer treats missing owner context as permission to read owned uploads;
+- vision/OCR cache and attachment metadata are prepared before model calls;
+- text-only models receive stripped multimodal blocks;
+- `src.document_processor.build_user_content()` produces model-ready text, PDF text, Office/EPUB text when MarkItDown or the DOCX fallback is available, image/multimodal blocks, truncation, and PDF/Office auto-document updates;
+- chat streams attachment, PDF-created `doc_update`, and `rag_sources` events where applicable.
+
+Extensionless image and audio attachments derive their data-URI subtype from
+the detected MIME type, so `image/png` and `audio/mpeg` uploads do not become
+invalid `data:image/;base64` or `data:audio/;base64` blocks when the filename
+has no extension.
+
+## Durable References And Cleanup
+
+`src.attachment_refs` owns the stable `attachment_ref` shape used outside raw
+upload storage: attachment id, name, MIME type, size, and optional checksum,
+creation time, dimensions, vision text/model, and gallery id. Live provider
+calls may still receive multimodal data URLs for the current turn, but durable
+chat content is normalized to readable text plus compact reference lines.
+Structured references remain in message attachment metadata, and chat FTS
+triggers omit inline media while startup migration scrubs legacy indexed data
+URLs.
+
+Agent/tool manifests expose `odysseus://attachment/<id>` with
+`read_policy: "owner_checked_upload"`. A compatibility filesystem path is
+included only after owner-aware upload resolution, upload-root confinement, and
+tool-readable-root checks; the stable contract for external tools is the URI
+and attachment id, not host layout.
+
+Writers reserve referenced uploads before committing durable state. This
+includes session message append/replace and history rewrites, document
+create/update and native document edits, note route/tool create/update,
+calendar/event route/tool create/update, and attachment-bearing session
+updates. A missing or wrong-owner reference aborts before destructive
+replacement and surfaces a route conflict or tool error. Reservations serialize
+with cleanup through the upload-index lock and refresh access time.
+
+Admin cleanup first scans chat content and attachment metadata, current and
+versioned documents including PDF markers, gallery filenames/hashes, note
+image/color/content/checklist fields, and calendar color/description/location
+fields. Reference discovery or index-integrity failure aborts cleanup; the
+lower-level API removes nothing without both completed id and hash snapshots.
+Only expired, unreferenced files with coherent id/path/owner/checksum/timestamp
+metadata are candidates. Matching index rows are persisted away before byte
+deletion and restored if deletion fails. This lock is process-local, so the
+documented race protection assumes the current single-worker deployment.
+
+## Living Documents And PDF
+
+`routes/document/document_routes.py` owns the HTTP document API: create/read/update/archive/delete, library listing, import/export, version history, tidy/AI tidy, PDF rendering/export, PDF form helpers, and email-attachment reply preparation. The top-level document route/helper modules remain compatibility aliases.
+
+`static/js/documentLibrary.js` owns local library state after archive/delete actions, including total counts and language chips. Server route truth still owns durable document state.
+
+`static/js/document.js` owns the browser document editor and markdown preview. Preview rendering applies code highlighting when highlight.js is present, renders Mermaid diagrams when the Mermaid runtime is available, refreshes after AI edits, and discards pending AI diffs before switching the active document.
+
+Document mutations also happen through agent tools, Codex document routes, email attachment import, and scripts. HTTP and native-agent document writers owner-reserve any internal upload/PDF references before persisting new current content or versions. Native document tool outputs include metadata that the browser can use to open/update the editor if a later stream update is missed. Those callers must preserve document owner, attachment, and version semantics.
+
+After external/workspace-untrusted context, a proposed document mutation is sealed into an exact approval with document id, current version, content digest, tool content, owner/session, and workspace. Approval continuation re-reads and verifies those fields before consuming the one-use authorization, so an intervening edit cannot apply a stale approved patch to new content.
+
+Email draft documents are a first-class document language. Create/update paths
+detect the `To`/`Subject`/header shape, coerce language to `email`, and preserve
+protected reply/forward headers such as `In-Reply-To`, `References`,
+`X-Source-UID`, `X-Source-Folder`, attachment headers, and quoted/original
+history when model or UI edits replace the draft body. Creating a draft for the
+same source UID/folder in the same session updates the active draft instead of
+creating a duplicate.
+
+`Document` rows own current content and owner. `DocumentVersion` rows own immutable snapshots. Document access should be owner-filtered, not session-id-only; the session document listing path still needs regression coverage for per-document owner filtering after the session owner check.
+
+PDF runtime behavior:
+
+- direct PDF import stores the upload through `UploadHandler`;
+- PDF library entries preserve metadata/preview behavior for source PDFs;
+- pypdf text extraction remains core;
+- PyMuPDF enables form detection, page rendering, page PNGs, annotation fill, render/export PDF, and form filling;
+- PDF render routes should return a shaped 503 when PyMuPDF is absent and use same-origin framing/download behavior for rendered pages;
+- imported PDFs become either plain `pdf_source` markdown or `pdf_form_source` markdown with sidecar field data;
+- PDF markers must resolve back through an upload owned by the caller;
+- signed-reply preparation uses document `source_email_*` provenance and verifies the document owner and signature owner. Source email account resolution still needs explicit owner-scoped coverage.
+
+Office/EPUB attachment extraction is optional and MarkItDown-backed for `.docx`, `.pptx`, `.xlsx`, `.xls`, and `.epub`; a pure-Python DOCX fallback can extract `word/document.xml`. When a session id is present, full extraction can be saved as a markdown `Document` while the chat-inline copy remains capped.
+
+## Personal Docs And RAG
+
+`src.personal_docs.PersonalDocsManager` owns personal-directory indexing and keyword retrieval.
+
+`src.rag_vector.VectorRAG` owns Chroma/embedding-backed indexing and owner-filtered retrieval. Chunk ids are owner-scoped so byte-identical chunks from different owners do not suppress each other. `src.rag_singleton` owns lazy initialization, retry throttling, and reset behavior.
+
+`routes/personal_routes.py` owns personal-doc and direct RAG-upload routes. Directory list/index/delete routes are admin-gated, and directory indexing runs in a worker thread so traversal/extraction does not block the async event loop. Direct RAG upload is user-authenticated, requires document privilege, forwards owner into the manager wrapper, writes unique files under per-owner subdirectories of `data/personal_uploads`, and has looser file-type validation than normal uploads.
+
+Current call sites include:
+
+- admin RAG pages and slash commands;
+- chat RAG preface building;
+- AI interaction and MCP RAG management tools;
+- CLI scripts for document/personal indexing.
+
+Some non-route tool/script paths can index ownerless or arbitrary directories and should be treated as compatibility-sensitive management surfaces.
+
+## Embedding Models
+
+`routes/embedding_routes.py` owns admin-gated embedding model and custom endpoint management. It validates custom endpoints with outbound URL checks, can persist and process-expose `EMBEDDING_API_KEY`, resets embedding/RAG/tool-index/Chroma state, and does not own document extraction.
+
+`src.embeddings` owns HTTP embedding fallback to FastEmbed and process-level endpoint state. `src.embedding_lanes` keeps custom HTTP embedding vectors separate from FastEmbed fallback vectors with lane-specific Chroma collections, migrates legacy unsuffixed collections into empty lanes, and dedupes query results across lanes. `src.chroma_client` owns native Chroma defaults and fast reachability checks.
+
+## Compatibility State
+
+`src.rag_manager.RAGManager` is a backward-compat wrapper. The live owner-aware vector path is `VectorRAG`.
+
+`services/docs/service.py` is a separate facade. It accepts live `VectorRAG` query rows (`document`, `similarity`, nested metadata source), retains legacy `text`/`content` and `score` fallbacks, skips non-object rows, and maps live `indexed_count`/`failed_count` plus legacy `indexed`/`failed` index summaries into its dataclasses.
+
+`src.database` re-exports `core.database`; document models and migrations live in `core.database`.
+
+## Optional And Degraded Behavior
+
+- ChromaDB/FastEmbed are default installed dependencies, but Chroma can be offline or unreachable.
+- Native Chroma defaults to `localhost:8100`; Docker uses the `chromadb:8000` compose service and persistent Chroma storage.
+- HTTP embeddings can fall back to FastEmbed; when both lanes exist, lane separation avoids Chroma dimension conflicts.
+- MarkItDown is optional for Office/EPUB extraction; chat attachments and personal directory indexing have clear degraded behavior, while direct RAG upload does not share the same extraction path.
+- PyMuPDF is optional, unlocks PDF form/render/fill paths, and carries AGPL implications when installed.
+- PyMuPDF-dependent document routes should use the shared runtime helper/error text so missing-dependency and license policy stay visible.
+- pypdf text extraction is core and should remain available without PyMuPDF.
+
+## Security And Provenance
+
+Uploaded files, documents, RAG chunks, extracted attachment text, OCR/vision text, PDF marker content, and source-email metadata are untrusted external or user-provided context when sent to an LLM.
+
+Concrete enforcement points include:
+
+- `UploadHandler.resolve_upload()` for upload ID validation, owner/admin access, and upload-dir confinement;
+- owner-checked write reservations before durable attachment references are
+  stored, sharing the upload-index lock with reference-aware cleanup;
+- PDF marker ownership checks before resolving source uploads;
+- personal-directory and personal-upload confinement helpers, including symlink/realpath checks before deleting uploaded files or removing indexed directories;
+- owner-filtered `VectorRAG.search(owner=...)`;
+- shared untrusted-context wrappers for RAG preface insertion.
+
+Extracted attachment text is currently appended into the user message rather than wrapped as a separate untrusted-context message. That is current behavior and a prompt-injection hardening gap.
+
+Bearer-token callers are not a scoped document/upload API surface today. Routes that treat token-authenticated users as owners need explicit scope/effective-user policy before they are considered safe token APIs.
+
+## Testing Coverage
+
+Existing useful coverage includes upload owner scope, upload IDs, upload atomicity, durable attachment reference normalization, message/document/note/calendar write reservations, fail-closed reference-aware cleanup, attachment budgets, `.nix` text upload handling, upload/PDF security regressions, Docker `libmagic`/`python-magic` upload detection, RAG owner fallback, Chroma fast-fail, MarkItDown runtime, PDF runtime, document-library counter updates, and selected document helper behavior.
+
+Route-level coverage is thinner for document CRUD, PDF import/render/export/fill, direct RAG upload, embedding admin/security behavior, and RAG unavailable states.
+
+## Current Gaps
+
+- Direct RAG upload still needs clearer file-type validation and MarkItDown/PDF extraction parity decisions.
+- Document `session_id` relinking and session document listing need owner-scope regressions.
+- Chat RAG can remain degraded after startup even if personal routes later initialize the RAG singleton.
+- PyMuPDF-dependent routes do not all share the same optional-runtime helper/error behavior.
+- Signed-reply preparation needs owner-scoped source email account/signature regression coverage.
+- Document/upload routes need explicit bearer-token scope/effective-user policy.
+- User-facing document/PDF/RAG route matrices need more regression coverage for owner denial, admin gates, unavailable services, and degraded optional dependencies.

+# Email And Contacts
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+This spec covers mail and contacts in:
+
+- app wiring in `app.py`;
+- `core.database.EmailAccount`;
+- `routes/email_routes.py`, `routes/email_helpers.py`, and `routes/email_pollers.py`;
+- email threading in `src/email_thread_parser.py`;
+- email MCP tools in `mcp_servers/email_server.py`;
+- canonical contact/CardDAV routes in `routes/contacts/contacts_routes.py`,
+  with `routes/contacts_routes.py` as a compatibility shim;
+- Codex email bridge in `routes/codex_routes.py`;
+- document signed-reply flows in canonical `routes/document/document_routes.py` and document `source_email_*` fields;
+- reminder/task email senders in `routes/note_routes.py` and `src/task_scheduler.py`;
+- email/contact agent surfaces in `src/tool_implementations.py`, `src/tool_schemas.py`, `src/tool_index.py`, and `src/agent_loop.py`;
+- CLI wrappers `scripts/odysseus-mail` and `scripts/odysseus-contacts`;
+- frontend modules `static/js/emailInbox.js`, `static/js/emailLibrary.js`, `static/js/emailLibrary/*`, `static/js/emailShared.js`, `static/js/chatStream.js`, `static/js/document.js`, and `static/js/settings.js`;
+- tests under `tests/test_email_*`, `tests/test_contacts_*`, `tests/test_mail_cli_*`, `tests/test_mcp_email_*`, `tests/test_schedule_email_*`, email/contact JS tests, and email security regressions.
+
+## Current Call Sites Include
+
+- browser email inbox/library, compose, schedule, account, and attachment actions;
+- document-editor compose, recipient autocomplete, compose uploads, and signed-reply handoff;
+- Codex email read/draft/send routes using API-token scopes;
+- note reminder and task-output email delivery;
+- built-in email summary/reply/calendar/urgency actions;
+- scheduled email pollers and CLI one-shot pollers;
+- MCP email tools;
+- contact manager settings, compose contact autocomplete, agent contact tools, and contacts CLI.
+
+## Email Accounts And Transport
+
+`EmailAccount` rows own IMAP/SMTP configuration. Password fields are string columns containing encrypted ciphertext written with `src.secret_storage`; startup migrations handle legacy plaintext rows. Google OAuth account rows also carry `oauth_provider`, encrypted access/refresh tokens, token expiry, and an optional outbound `display_name`. Do not return decrypted credentials or OAuth tokens, or write them to logs.
+
+Exactly one default account per owner is enforced as a serialized database transition. Startup normalizes legacy duplicate defaults and installs a unique per-owner default constraint/index; first create, delete/promotion, set-default, demo teardown, and owner rename lock the relevant owner rows and commit atomically. Multi-owner rename acquires locks in canonical order so stale concurrent writers fail closed.
+
+`routes.email_helpers` owns:
+
+- account owner assertions and config fallback order;
+- IMAP/SMTP connection helpers and related transport utilities;
+- Google OAuth2 state signing/verification, token refresh, and XOAUTH2 framing;
+- SMTP security modes (`ssl`, `starttls`, `none`);
+- envelope recipients and Odysseus headers;
+- attachment extraction helpers;
+- email pre-retrieval context for AI reply drafting;
+- scheduled email, summary, reply, tag, calendar extraction, urgency, and signature-boundary side databases.
+
+Email config can fall back to legacy `data/settings.json` or environment variables when no scoped account is configured. Account discovery now owner-scopes the default/first-enabled fallback and can still match legacy account rows by IMAP username or from-address. That fallback remains compatibility-sensitive in multi-user contexts.
+
+Email owner semantics are route-local and compatibility-sensitive:
+
+- `routes.email_helpers._require_auth()` returns `""` in `AUTH_ENABLED=false` mode, rejects configured auth with no user, and only tolerates first-run anonymous loopback fallback.
+- Empty owner is treated as single-user compatibility: account-ownership assertions no-op, default/first-enabled account fallback can be global, and email cache clauses include `owner = '' OR owner IS NULL`.
+- Non-empty owners scope account/config/cache queries. Legacy ownerless account
+  rows are visible to an authenticated owner only when the row's IMAP username
+  or from-address matches that owner, so old unowned rows do not become global
+  cross-user accounts in configured multi-user deployments.
+
+`routes.email_routes` owns the HTTP mail surface:
+
+- account CRUD, test, default, and masked config reads;
+- Google OAuth authorize/callback for Workspace and .edu Gmail-style accounts;
+- list, search, read, folders, and contacts;
+- folder role resolution and UID fetch/search helpers used by the route surface;
+- owner-scoped route caches and IMAP pool behavior;
+- attachments, bulk attachment ZIP downloads, and attachment-to-document flows;
+- compose upload, draft/send, `wait_for_delivery`, Sent append, and source `\Answered` marking;
+- schedule/list/delete scheduled emails;
+- pending agent-draft approval/cancel flows;
+- mark read/unread/answered, spam flags, move, archive, and delete. IMAP move/delete/archive operations use UID commands for message identity and fail safe when the requested UID no longer exists; they never reinterpret a missing UID as a sequence number, which could mutate or expunge an unrelated message.
+
+Google OAuth behavior is account-owned:
+
+- `/api/email/oauth/google/authorize` requires an authenticated owner, checks account ownership, HMAC-signs state with account id, owner, and nonce, and redirects to Google with mail/userinfo scopes;
+- `/api/email/oauth/google/callback` verifies signed state before token exchange, re-checks the target account owner before writing tokens, stores access/refresh tokens encrypted, stores token expiry as a timestamp, and redirects with generic success/error codes rather than raw provider errors;
+- token refresh uses `GOOGLE_OAUTH_CLIENT_ID` and `GOOGLE_OAUTH_CLIENT_SECRET`, stores refreshed access tokens encrypted, and logs only generic/account-id context on failures;
+- SMTP and IMAP use XOAUTH2 when `oauth_provider == "google"`; OAuth accounts are send-capable without an SMTP password when host and user are configured;
+- outbound mail formats the `From` header with `display_name` when present.
+- authorize/callback redirect URIs derive their scheme and host from the mounted request unless `GOOGLE_OAUTH_REDIRECT_URI` explicitly pins a value; the browser preserves the selected SMTP security mode during connect and reopens Settings after the callback.
+
+MCP full-message read/reply/attachment fetches use IMAP `BODY.PEEK[]` rather than bare `RFC822`, so iCloud-style servers return the full body without marking messages seen. Poller UID handling must tolerate both bytes and string UIDs. Built-in signature-learning and daily-brief actions also use UID SEARCH/FETCH rather than sequence-number commands.
+
+IMAP helpers quote mailbox names, raise the Python IMAP line cap for large messages, close sockets after connect/login failures, and preserve Gmail FETCH attributes that follow header literals so unread flag state is not lost. Browser list routes offload blocking IMAP work from async handlers; browser search runs in FastAPI's threadpool, rejects CRLF query input, tokenizes quoted phrases/terms, searches FROM/TO/CC/SUBJECT/TEXT, can search Gmail All Mail when an INBOX query should include archived or labelled messages, and supports `scope=folder` when callers intentionally want the selected folder only. The local index fallback can return indexed results when IMAP returns empty or fails.
+
+## Runtime And Pollers
+
+Scheduled email rows live in `data/scheduled_emails.db` and are owner-scoped. Scheduled send times are normalized before storage.
+
+`routes.email_pollers` owns the scheduled-send poller and single-shot/task/CLI automation passes. Before SMTP work, each poller atomically claims a due row with a conditional `pending` to `sending` update; concurrent in-process/CLI pollers that lose the claim skip the row instead of sending a duplicate. Only the scheduled-send poller starts in-process by default when `ODYSSEUS_INPROCESS_POLLERS` allows it; Docker forwards that gate. Background email automation can also consult the foreground activity gate so auto actions do not compete with active browser/model work. Native cron/systemd can drive one-shot pollers through `scripts/odysseus-mail`.
+
+Manual and scheduled summaries use the shared LLM adapter and owner-scoped cache instead of constructing provider calls locally. Scheduled summaries use background fallback policy and yield to foreground work; provider exception text is shaped before it can reach the browser.
+
+Urgency delivery publishes through a serialized atomic checkpoint transaction. Generation and membership fences prevent stale scans from overwriting newer state; authoritative scans retire deleted/disabled accounts, partial failures preserve the prior checkpoint, concurrent account-scoped actions merge disjoint facts, and cancellation rolls back without publishing.
+
+Transport degraded behavior:
+
+- IMAP timeouts are clamped by configuration;
+- providers can use implicit SSL, STARTTLS, or plain connections;
+- poisoned IMAP sockets are reconnected around known provider failures;
+- SMTP-capable account fallback is used where supported;
+- route helpers, MCP, and CLI do not all share identical SMTP/IMAP parsing and security behavior today.
+
+## Caching And Staleness
+
+Email list/read behavior uses short route caches, longer read caches, capped warm prefetch, and owner/account-aware pool/cache keys. The frontend email library has its own session SWR cache, cache-buster refreshes, scheduled/search cache exclusions, and stale-row behavior when refresh fails.
+
+Opening an unread message is one authoritative backend IMAP operation. The read route fetches/parses the message and applies `\Seen` over the same connection; cached bodies still await one UID STORE, read-only mailboxes serve content without claiming a mark, and STORE failure returns the body with explicit failure state rather than caching a false read. Inbox/library clients deduplicate opens, carry immutable mailbox context, and ignore late responses after account, folder, or message changes.
+
+Library prewarm runs only while genuinely idle, as one bounded single-flight request for the default or last-used enabled account and initial page. Visible foreground work, panel lifecycle, account changes, or explicit reads cancel or join it so delayed duplicate IMAP work cannot escape the idle gate.
+
+List/read route caches are owner/account-aware. Helper-side summary, AI-reply, tag, calendar-extraction, urgency-alert, and learned sender-signature tables carry owner columns and owner clauses. Thread-boundary rows are still keyed by message shape rather than a full owner/account/mailbox key, so they remain cross-owner audit points when identical messages appear in multiple mailboxes.
+
+## Attachments And Signed Replies
+
+Compose uploads live under `ODYSSEUS_MAIL_ATTACHMENTS_DIR`; missing staged files are skipped with warnings. Attachment-to-document supports PDF, DOCX, TXT, and MD. DOCX depends on `python-docx`; PDF form/open-in-doc flows can depend on optional PyMuPDF.
+
+Email attachment-as-document flows stamp `Document.source_email_*` provenance. `GET /api/email/attachments-download/{uid}` builds an owner-scoped ZIP of visible non-signature attachments using safe names. `compose-from-odysseus` and `compose-from-odysseus-zip` can stage owner-visible documents and gallery images as compose uploads, preserving legacy session fallback only where the source object remains visible to the owner. `prepare-signed-reply` verifies document ownership, reconstructs reply headers, flattens/stages signed PDFs as compose uploads, and leaves final send/draft review to the compose flow.
+
+Email bodies and attachments are untrusted model context.
+
+## Threading And Rendering
+
+`src.email_thread_parser` owns splitting plaintext/HTML email threads into quoted conversation parts. Frontend email library modules own reply-recipient logic, signature folding, local state, and rendering behavior. Bulk selections are cleared when folder/account loads, search text, search pills, or result scope changes so actions cannot carry stale UIDs into a different visible context. `static/js/emailShared.js` owns shared email UI helpers used across inbox/library surfaces.
+
+Remote inbound email HTML is sanitized by frontend email-library utilities before `innerHTML` insertion. Server-side email routes sanitize composed/generated outbound HTML with an allowlist before draft/send, dropping scripts/styles and unsafe attributes. Both sides are part of the rendering invariant.
+
+When the email reader is active, browser chat sends selected-message metadata. `src.tool_implementations` stores that request-local active email reference, `src.agent_loop` injects it as protected untrusted context, and `static/js/chatStream.js` handles `ui_control open_email_reply` so default reply/draft behavior opens the selected message's compose flow instead of a generic new document.
+
+## MCP Email
+
+`mcp_servers/email_server.py` exposes email tools for MCP/agent use. It has its own account discovery, IMAP/SMTP, attachment, cache, and send paths, but account visibility now mirrors the HTTP owner policy. The active owner comes from a hidden `_odysseus_owner` argument when the caller provides one, or from `ODYSSEUS_MCP_EMAIL_OWNER` / `ODYSSEUS_EMAIL_OWNER`. If any enabled account is owner-scoped and no current/configured owner exists, email MCP returns an owner-scope error instead of listing global accounts.
+
+MCP email account filtering includes owner-owned rows and legacy ownerless rows
+whose mailbox/from-address matches the owner. Confirmation-first `send_email`
+resolves the selected account before stashing an `agent_draft`, so drafts cannot
+be staged against another owner's account. MCP-created draft documents use the
+resolved hidden/configured owner when available, with `ODYSSEUS_DOCUMENT_OWNER`
+and single-admin fallback only as document-visibility compatibility.
+
+MCP email send behavior is confirmation-first by default: `send_email` and reply send paths stash a `scheduled_emails` row with `status='agent_draft'` when `agent_email_confirm` is true, and browser routes expose pending drafts for approval or cancellation. Separate MCP draft tools create Odysseus compose documents for user review without sending.
+
+MCP email remains a separate local/admin trust boundary. Public and non-admin users must not see or execute email MCP tools. It still needs route-helper parity audits for attachment path containment, sanitization, transport behavior, and pending-draft result text, but global all-account behavior is no longer the current owner model.
+
+## Contacts
+
+`routes.contacts.contacts_routes` owns global/admin contacts and CardDAV behavior. The top-level `routes.contacts_routes` module is a compatibility shim. The canonical package supports local contacts, CardDAV config, list/search/add/update/delete, VCF/CSV import/export, and clear.
+
+Contact runtime behavior:
+
+- contacts routes are admin-gated;
+- local `data/contacts.json` is used when CardDAV is unconfigured;
+- import paths tolerate malformed or non-string contact bodies by skipping invalid rows instead of crashing the import;
+- configured CardDAV uses REPORT with GET fallback and a short in-memory cache;
+- configured-but-offline CardDAV can return cached reads but writes fail instead of falling back to local JSON;
+- CardDAV config reads mask the password, settings-stored passwords are encrypted with `src.secret_storage`, omitted password updates preserve the existing secret, and an explicit empty password clears it;
+- the native contacts CLI is CardDAV-oriented and does not fully match web JSON fallback behavior;
+- agent contact tools reuse helper functions in-process because the HTTP routes require browser/admin auth.
+
+Contacts are global admin-only data today. There is no per-user contact sharing model unless a future spec defines one.
+
+## Security Policy
+
+Email HTTP access is owner-scoped, including account selection, scheduled email rows, and attachment routes. Null-owner/single-user compatibility paths are security-sensitive and must not allow cross-user mailbox access.
+
+Codex email routes are the scoped bearer-token email API. They enforce `email:read`, `email:draft`, and `email:send` scopes and use token-owner attribution before borrowing email route handlers.
+
+Known security policy details:
+
+- decrypted email credentials stay process-local;
+- account/config reads mask passwords and expose only OAuth status fields, not access or refresh token values;
+- SMTP/IMAP security mode behavior is part of the credential contract;
+- Google OAuth state and callback owner checks are part of the account-boundary contract;
+- scheduled emails must remain owner-scoped;
+- email pre-retrieval contacts context is allowed only for admin/single-user situations;
+- MCP attachment downloads need route-level path-containment parity; current MCP paths are separate from the HTTP compose/attachment helper path.
+
+CardDAV credentials and URLs are security-sensitive. CardDAV URL setup and derived href writes/deletes pass through outbound URL validation; absolute hrefs from a CardDAV server are constrained back to the configured origin before credentials are reused. CardDAV passwords in settings are encrypted and masked on read; environment-sourced legacy password values are used as supplied.
+
+## Degraded Behavior
+
+- IMAP/SMTP providers can be slow or inconsistent; folder resolution, pooled connections, and reconnect behavior should fail with clear errors.
+- Google OAuth requires external Google endpoints plus configured `GOOGLE_OAUTH_CLIENT_ID`/`GOOGLE_OAUTH_CLIENT_SECRET`; missing client credentials or refresh failures degrade to reconnect-required or generic OAuth error paths.
+- Scheduled email delivery depends on `scheduled_emails.db`, poller runtime, and configured SMTP.
+- Attachment handling must tolerate missing staged files, unsupported formats, and inaccessible remote messages.
+- CardDAV local fallback applies only when CardDAV is unconfigured; configured CardDAV outages are not treated as local-write mode.
+- Multi-account list/search behavior can be sequential and cache-sensitive.
+
+## Testing Coverage
+
+Existing coverage includes header/envelope/IMAP/SMTP behavior, serialized default accounts, Google OAuth state/callback/token-refresh/XOAUTH2/redirect/settings behavior, shared-adapter summaries, authoritative read/mark-seen and frontend dedup, idle prewarm, UID-only mutations, scheduled-email claims and urgency checkpoint transactions, MCP full-message/owner behavior, owner scope/caches/signatures, thread/sanitizer behavior, CardDAV password encryption, mail CLI behavior, contacts basics, and selected frontend/security regressions.
+
+Route-level and duplicate-path coverage is still thin for email list/read/search/mutations, account CRUD/security outside the OAuth path, send/draft security, attachments, scheduled-poller failures, contacts admin/CardDAV routes, MCP account/scope behavior, CardDAV degraded mode, and executable frontend behavior.
+
+## Current Gaps
+
+- Owner-keyed cache policy still needs an explicit decision for thread boundaries, plus continued migration/query audits for every email side table.
+- CardDAV still needs redirect/proxy policy and broader route-level tests for URL validation, private-address blocking configuration, and same-origin href enforcement.
+- MCP email needs continued route-helper parity for attachment path containment,
+  sanitization, transport behavior, and pending-draft result text.
+- Empty-owner route compatibility and ownerless email cache rows need
+  end-to-end owner-boundary tests.
+- CLI send/contact paths need parity decisions for SMTP security, recipient parsing, local fallback, and normalized contact shapes.
+- Email HTTP route coverage is concentrated in scheduling/account-test helpers rather than full list/read/search/mutation/send/draft/account/attachment flows.
+- Contacts coverage lacks admin-gate, config masking, import/export, CardDAV fallback, and CardDAV write-failure tests.
+- Multi-account performance and cache staleness remain known audit areas.

+# Frontend
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers the current browser app in:
+
+- static serving and SPA routes in `app.py`;
+- CSP/security headers in `core/middleware.py`;
+- `static/index.html`;
+- `static/login.html`;
+- `static/app.js`;
+- `static/style.css`;
+- `static/js/*.js` and `static/js/*/*.js`;
+- vendor libraries under `static/lib/*`;
+- custom fonts and static assets under `static/fonts/*`;
+- `static/sw.js` and `static/manifest.json`;
+- frontend-oriented tests in `tests/*_js.py`, `tests/*.mjs`, `tests/bombadil-spec.ts`, static DOM/CSS/source-shape tests, and app/static tests such as `tests/test_app_static_mime.py`.
+
+`/backgrounds` currently targets `static/backgrounds.html`; if that route remains, the file must exist or the route should be removed.
+
+`static/manifest.json` and `static/index.html` reference PWA icon files under `static/icons/`; the current 192px, 512px, and maskable icon files exist and should stay aligned with those references.
+
+## Current Call Sites Include
+
+- `static/index.html` script tags and modulepreloads;
+- `static/sw.js` `PRECACHE`;
+- app-owned SPA deep links for notes, calendar, cookbook, email, memory, gallery, tasks, and library;
+- `/login` and app-owned static/HTML routes;
+- `/api/activity/heartbeat` browser visibility pings used by the foreground activity gate;
+- `static/app.js` route opener/sidebar/tool-window wiring;
+- frontend JS helper tests and static HTML/CSS/source-shape regressions;
+- CDN dependencies, local vendor libraries, service worker, and PWA manifest.
+
+## Runtime Shape
+
+The frontend is a raw static SPA served by FastAPI. There is no Vite, React, TypeScript, bundler, or generated build output.
+
+`app.py` owns:
+
+- stable `.js`/`.mjs` MIME registration;
+- the `/static` mount;
+- no-cache headers for `.js`, `.css`, and `.html` static source files;
+- nonce-injected SPA/login HTML serving;
+- SPA deep-link routes.
+
+`static/index.html` owns the DOM shell and script loading order. It loads browser ES modules directly. Current boot order includes nonce-bearing inline boot scripts, self-hosted highlight.js, modulepreloads, ordered module script tags, `static/app.js`, `static/js/init.js`, `static/js/a11y.js`, workspace/chat helpers, provider device-flow helpers, and service-worker registration. KaTeX and Mermaid are vendored under `static/lib` and injected only on first real math/diagram use rather than loading in the initial HTML.
+
+The two first-paint Fira Code faces are preloaded so the shell does not wait for later CSS discovery. `static/js/startupShell.js` lets the visible shell initialize before session loading completes; session/transcript hydration is deferred and coordinated by `static/js/sessions.js` plus history/session routes rather than blocking first paint.
+
+Exact script URL identity matters. Versioned script tags, unversioned imports, and service-worker precache entries must stay aligned. `static/sw.js` deliberately separates first-paint `PRECACHE` from lazy `PANEL_PRECACHE`; the latter currently contains the image-editor module graph so an editor never opened online can still open offline. KaTeX scripts/styles/fonts are also precached. Current service-worker coverage is not a generated full module-graph manifest, so changes still need direct verification.
+
+## Security Policy
+
+`core/middleware.py` owns CSP and security headers. `app.py` injects the per-request nonce into served HTML. New inline scripts or external scripts/styles/images/media must fit the CSP contract or explicitly update it.
+
+`/static/*` is public/auth-exempt. Frontend privilege gates are display-only; backend routes enforce authorization.
+
+XSS/DOM policy:
+
+- prefer DOM construction, `textContent`, and shared escaping helpers;
+- Markdown raw HTML preservation must remain constrained through sanitizer helpers;
+- remote email `body_html` must pass through the email-library sanitizer before insertion;
+- Mermaid, code-runner iframe `srcdoc`, visual reports, remote media, and scattered `innerHTML` templates require explicit review.
+- Visual report Markdown HTML is server-rendered and should be treated as security-sensitive alongside frontend entry points and remote media.
+
+Storage/secrets policy:
+
+- localStorage/sessionStorage are for preferences, UI state, offline caches, and user-switch sentinels;
+- `static/js/init.js` owns user-switch storage cleanup;
+- raw API tokens, provider keys, HF tokens, and other credentials must not be persisted in browser storage unless a feature documents masking/stripping and backend storage ownership.
+
+## Service Worker And PWA
+
+`static/sw.js` owns PWA cache behavior:
+
+- API and non-GET requests are bypassed;
+- root navigation uses stale-while-revalidate;
+- JS/CSS use network-first behavior;
+- other static assets use cache-first with background refresh;
+- `CACHE_NAME` bumps and `PRECACHE` updates must accompany cache policy or shell asset changes.
+
+`static/manifest.json` owns default PWA metadata. Route-specific manifests can be generated as Blob URLs when supported. Current default icon references must match real files under `static/icons/`.
+
+KaTeX and Mermaid are self-hosted and lazy-loaded through memoized, retry-after-failure promises in `static/js/markdown.js`; math placeholders preserve source until KaTeX arrives, detached PDF export renders its own container, and Mermaid fetches only when a diagram exists. Pyodide remains a jsDelivr-loaded optional runtime, so offline/PWA behavior is not fully self-contained.
+
+## Module Ownership
+
+Current major frontend areas include:
+
+- chat, stream handling, rendering, sessions, markdown, uploads, voice recorder, TTS, and keyboard shortcuts;
+- models, provider setup, pure model-key matching helpers, model picker, presets, search, RAG, settings, and admin;
+- settings shell modules under `static/js/settings/`: registry metadata, navigation, finder search, lifecycle/docking, DOM helpers, and persisted sidebar collapse/resize behavior;
+- compare modules under `static/js/compare/`, including sanitized popup/search/image handling;
+- document editor/library in `static/js/document.js` and `static/js/documentLibrary.js`;
+- image editor integration in `static/js/galleryEditor.js` plus leaves under `static/js/editor/`;
+- gallery, email inbox/library, calendar, research panel/jobs/synapse, notes/tasks, assistant, memory/skills, Cookbook/HW Fit, workspace picker, provider device flow, composer ArrowUp recall, theme, modal/window utilities, storage, and accessibility helpers.
+
+Coordinator ownership:
+
+- `static/app.js` owns late orchestration, global fetch 401 redirects, sidebar/tool route wiring, and many `window.*` compatibility bridges;
+- `static/js/init.js` owns post-load cleanup, user-switch storage wipe, and cosmetic privilege gates;
+- `static/js/storage.js` owns shared key constants and safe JSON helpers;
+- feature modules own feature state where possible.
+
+`static/js/appConfig.js` owns one invalidatable promise cache for `GET /api/auth/settings` and `GET /api/tools`, including one-shot login-page settings prefetch, retry after rejected fetches, and explicit invalidation after settings/tool writes. Consumers treat resolved objects as read-only. `static/js/panels.js` owns memoized first-use panel imports; its current registry contains the image editor, shares in-flight imports, and evicts failed imports so a later online retry can succeed.
+
+`static/js/MODULE_SUMMARY.md` is a refreshed ownership/navigation map for the no-build frontend. The current `static/js/` tree, `static/app.js`, `static/index.html`, and executable behavior remain the authority when the summary drifts.
+
+Current small frontend helper contracts include `static/js/model/matchKey.js` for longest-substring model info/pricing matches, `static/js/models.js` for in-flight `/api/models` request sharing, `static/js/providerDeviceFlow.js` for Copilot/ChatGPT Subscription device-flow polling UI, `static/js/composerArrowUpRecall.js` for prompt recall from an empty composer, `static/js/fileHandler.js` for capped pending-file state and collapsed attachment-chip display, `static/js/streamingSegmenter.js` for incremental markdown/code-fence segmentation, `static/js/emojiShortcodes.js` for shortcode replacement, `static/js/documentLibrary.js` for keeping document counters/language chips in sync after archive/delete, `static/js/keyboard-shortcuts.js` for rejecting empty or non-string persisted keybinds before combo parsing, `static/js/modalSnap.js` for reusable desktop modal edge docking, `static/js/toolWindowZOrder.js` for shared portal/window z-index allocation, and `static/js/emailShared.js` for common email UI helpers.
+
+Recent browser behavior contracts include mobile chat Enter inserting newlines while desktop Enter submits; ArrowUp recall only consuming a truly empty composer with the caret at the top, not an unsent multiline prompt; queued prompts preserving mobile behavior; regenerate-from-here versus resend; AI-message delete confirmation; native document tool results opening/updating the editor; and exact tool-approval cards that expose the sealed action/effects/workspace/document identity and submit only opaque task-scope/chat-session-scope/deny decisions without writing synthetic composer text. Chat rendering hides leaked tool JSON/document fences, no longer strips the ordinary word “assistant,” and batches live-thinking DOM updates with bounded timers. Markdown editing/restoration preserves extracted code/math blocks verbatim, including replacement-string `$&` and `$$` text and triple-backtick fences. Session URL hashes are restored, minimized sidebar icon state follows per-tab visibility, detached terminal dots remain centered, and spinner animation starts only when attached.
+
+The Settings finder and navigation are registry-backed, hide admin-only destinations from non-admin users, lazy-load admin panels, and keep the registry synchronized with DOM panels. Email OAuth connect preserves SMTP security and reopens the settings surface; unread message opens use one authoritative backend read/mark-seen request with stale-response guards; email-library prewarm is idle-only, single-flight, bounded to the initial page, and cancelled around visible foreground work.
+
+## UI Policy
+
+- New code must run as browser ES modules without a build step.
+- Reuse existing CSS variables, modal/window patterns, icon style, storage helpers, and route conventions.
+- Custom font handling includes bundled OpenDyslexic assets plus user-supplied fonts exposed through `/api/fonts/custom`; font and text-size settings must stay coordinated between settings UI, theme helpers, and CSS variables.
+- Avoid relying on stale module summaries.
+- API shape changes must update the owning JS module and tests.
+- Add behavior to large coordinators such as `static/app.js`, `static/js/chat.js`, `static/js/document.js`, or `static/js/settings.js` only when it matches their existing wiring ownership.
+
+## Degraded And Platform Behavior
+
+- Server no-cache applies to `.js`, `.css`, and `.html` source files, not every static asset.
+- Service-worker cache changes can affect frontend behavior even when source files revalidate.
+- Mobile behavior uses separate CSS/media/hover/safe-area/`100dvh` handling and JS layout code; check it directly.
+- Browser APIs such as service workers, Blob route manifests, Web Speech, `getUserMedia`, visual viewport, and storage can be absent or restricted.
+- Local libraries and CDN globals degrade differently; document, markdown, math, diagrams, and code runner flows should handle missing globals where possible.
+- localStorage migrations and cross-user cleanup are part of compatibility.
+
+## Testing Coverage
+
+Existing frontend coverage is a mix of Node-executed helper tests, `.mjs` tests, static DOM/CSS/source-shape tests, browser exploration specs, and app/static tests. Many tests are useful source-shape regressions but do not replace browser/module-graph execution.
+
+Recent focused coverage includes model-key matching under Node, document-library counters, chat resend/delete/mobile Enter/ArrowUp, scoped approval continuation and compare routing, route provenance, live-thinking throttling, startup shell/history hydration, shared app-config caching/invalidation, settings registry/navigation/finder/lifecycle, lazy panel loading/offline editor precache, vendored lazy KaTeX/Mermaid rendering, email read dedup/prewarm, Markdown restoration, malformed keybinds, currency-safe inline math, notes/calendar/modal/manifest/admin-log behavior, Markdown XSS helpers, and CardDAV unchanged-password handling.
+
+Missing coverage includes:
+
+- SPA route/static auth and no-cache headers;
+- CSP header contents and nonce injection for `/` and `/login`;
+- service-worker API/non-GET bypass and cache strategy;
+- service-worker precache versus `index.html` script/module tags, including query strings;
+- ongoing manifest/icon reference drift;
+- module graph/load-order validation;
+- degraded vendor-library/browser API behavior, including Pyodide's remaining CDN path.
+
+## Current Gaps
+
+- `static/style.css` and large coordinators remain high-risk owners: `static/js/document.js`, `static/js/settings.js`, `static/js/chat.js`, and `static/app.js`.
+- There is no build-time type checking, module graph validation, script-order validation, or service-worker precache validation.
+- Frontend state is mostly module/global/localStorage driven, so cross-session and cross-user behavior needs explicit care.
+- `window.*` compatibility bridges remain widespread.
+- PWA/static-serving behavior may deserve a separate spec if service worker, manifests, route-specific icons, and cache policy keep growing.
+- A static asset/route manifest regression should verify files referenced by `index.html`, `manifest.json`, `sw.js`, and app-owned HTML routes actually exist.

+# Gallery, Editor, And Media
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers media surfaces in:
+
+- app route registration and generated-file serving in `app.py`;
+- canonical models in `core/database.py`, with `src.database` as a compatibility import path;
+- canonical route package `routes/gallery/gallery_routes.py` and `routes/gallery/gallery_helpers.py`, with top-level `routes/gallery_routes.py` and `routes/gallery_helpers.py` compatibility shims;
+- generated-image writers in `src/ai_interaction.py` and `mcp_servers/image_gen_server.py`;
+- local MLX image compatibility server `scripts/mlx_image_server.py`;
+- image tool schemas/dispatch/implementations in `src/tool_schemas.py`, `src/tool_execution.py`, and `src/tool_implementations.py`;
+- `routes/editor_draft_routes.py`;
+- `routes/signature_routes.py` and document signature consumers in canonical `routes/document/document_routes.py`;
+- `routes/emoji_routes.py`;
+- `routes/font_routes.py`;
+- `src/generated_images.py`;
+- `src/visual_report.py` plus research image hide/unhide routes;
+- database models `GalleryImage`, `GalleryAlbum`, `EditorDraft`, and `Signature`;
+- generated files under `data/generated_images`;
+- frontend modules `static/js/gallery.js`, `static/js/galleryEditor.js`, `static/js/editor/*`, `static/js/signature.js`, `static/js/emojiPicker.js`, `static/js/chatRenderer.js`, `static/js/document.js`, `static/js/markdown.js`, and `static/js/theme.js`;
+- CLI surfaces `scripts/odysseus-gallery` and `scripts/odysseus-signature`;
+- tests covering gallery helpers/routes, generated-image serving, editor drafts, signatures, visual reports, fonts, upload limits, and image endpoint security.
+
+## Current Call Sites Include
+
+- gallery upload, library, album, tag, favorite, ZIP, delete, and saved-project views;
+- chat-generated image rendering/edit/delete bubbles;
+- agent `generate_image` and stale `edit_image` tool paths;
+- MCP image-generation rows/files;
+- image editor AI tools and model endpoint pickers;
+- document PDF signing with stored signatures;
+- visual-report hero/section image insertion and research hide/unhide controls;
+- emoji picker/markdown emoji SVG proxy calls;
+- theme custom-font loading;
+- local gallery/signature CLI inspection.
+
+## Gallery
+
+`routes.gallery.gallery_routes` owns gallery upload/import/library/editor transform behavior: upload dedupe, image/video extension handling, EXIF extraction for images, albums, favorites, tags, generated media metadata, search/filter/sort, owner filtering, ZIP downloads, soft delete, disk cleanup, and chat-history cleanup after image delete. Top-level `routes.gallery_routes` is a `sys.modules` compatibility shim to the canonical module.
+
+Frontend gallery behavior includes upload progress, folder-drop album import, stale-while-revalidate cards, saved editor projects, detail actions, bulk delete/download, and cache-busted image refreshes.
+
+Album assignment and gallery image detail/update endpoints enforce owner scope and fail closed when no authenticated owner is available instead of falling back to broad access.
+
+Generated media provenance:
+
+- generated filenames are opaque hex-like media names, not trusted content hashes;
+- upload `file_hash` is a separate metadata field;
+- generated files live under `data/generated_images`;
+- chat image generation writes files and inserts `GalleryImage` rows through `src.ai_interaction`;
+- MCP image generation can create ownerless rows/files;
+- generated-but-not-yet-imported images can have no gallery row;
+- once a gallery row exists, owner checks decide visibility where the route enforces them.
+
+`app.py` owns direct `/api/generated-image/{filename}` serving through `src.generated_images.resolve_generated_image_path()`. It validates hex-like image/video filenames, rejects path escape and missing files, serves rowless generated files, checks row owner when a row exists, allows null-owner compatibility rows, and uses immutable/nosniff cache headers. Gallery replace/rotate/save/delete/ZIP paths also resolve filenames through a shared generated-image path helper so database filenames cannot escape `data/generated_images`. Replace/rotate/save-over-original flows can mutate bytes under the same filename, so frontend cache busting matters.
+
+## Image Tools And Providers
+
+Gallery/editor image transforms are split across:
+
+- `/api/gallery/ai-upscale` and `/api/gallery/style-transfer`;
+- `/api/image/inpaint`;
+- `/api/image/harmonize`;
+- `/api/image/sharpen`;
+- `/api/image/denoise`;
+- `/api/image/upscale-local`;
+- `/api/image/remove-bg`;
+- `/api/image/enhance-face`.
+
+AI image endpoints mostly require image-generation privilege in the gallery route layer. The sharpen route is explicitly auth-gated; utility routes that live outside gallery still need their own route-level gate checks rather than assuming a shared decorator. The chat image-generation session path calls `do_generate_image()` separately and has its own privilege/tool-listing behavior.
+
+Provider behavior:
+
+- OpenAI image edits use multipart `/images/edits`, mask conversion, size coercion, model restrictions, and source compositing where needed;
+- diffusion/self-hosted paths use JSON APIs such as inpaint, img2img, variations, harmonize, or A1111-compatible fallbacks;
+- client-supplied endpoint URLs on selected routes must pass outbound endpoint validation; DB-selected image endpoints should be resolved through owner-visible endpoint queries before decrypted headers/keys are used;
+- provider-returned image result URLs are validated with `src.url_safety.check_outbound_url()` before server-side download, with private-IP blocking controlled by image-route settings;
+- AI endpoint path suffixes are allowlisted before proxy/download use so arbitrary endpoint paths cannot be selected through gallery/editor requests;
+- editor model pickers load `/api/model-endpoints` and classify image-capable endpoints.
+
+Optional dependency behavior:
+
+- Pillow-backed paths are effectively core for EXIF, rotate, sharpen, and image preparation;
+- Real-ESRGAN powers denoise/upscale when installed and otherwise returns install guidance; import-time torchvision compatibility patches run before Real-ESRGAN imports;
+- remove-bg tries `rembg`, then transformers-style fallback, then an error;
+- face enhancement falls back from GFPGAN/OpenCV toward PIL behavior;
+- video uploads intentionally skip EXIF/ffprobe metadata today.
+- grounding and mask model inputs cast only `float64` tensors to `float32` before transfer to Apple's MPS backend, because MPS rejects float64; integer/other tensors and non-tensor processor values preserve their normal device-transfer behavior.
+
+## Editor Drafts
+
+`routes.editor_draft_routes` owns server-backed image editor project payloads. `EditorDraft` rows store title, payload JSON, thumbnail, source image, timestamps, and owner.
+
+Frontend editor behavior is split across `static/js/editor/*` and `static/js/galleryEditor.js`: canvas state, layer panel, masks, history, snapping, stroke pipeline, inpaint/rembg/harmonize tools, AI tool runner, model pickers, an AI edit command box that routes natural-language edit requests into existing inpaint/remove/upscale/background/style actions where possible, import wiring, topbar controls, auto-save, resume by draft ID or source image, draft-only open, and cleanup after close. `static/js/panels.js` loads this module graph on first editor use, shares concurrent imports, retries failed loads, and `static/sw.js` keeps the lazy graph in a separate offline panel precache.
+
+Draft compatibility behavior:
+
+- v2 server drafts store payloads and thumbnails server-side;
+- legacy/local raw payloads can still be restored by the frontend;
+- PUT 404 can recreate a missing draft row;
+- broken image drafts can fall back to the source image;
+- final close persist is best-effort.
+
+## Signatures, Emoji, Fonts
+
+`routes.signature_routes` owns reusable signature/stamp rows. Signature image payloads are normalized to bounded PNG base64, encrypted at rest, and owner-filtered; SVG signature input is not preserved. Document PDF render/export paths owner-filter signature IDs before stamping.
+
+`routes.emoji_routes` owns same-origin OpenMoji black SVG proxy/caching. It validates codepoint filenames, caches SVGs under `data/emoji_cache`, and returns transparent no-store SVGs for invalid, unknown, or unreachable codepoints. `static/js/emojiPicker.js` is a curated inline monochrome picker.
+
+`routes.font_routes` owns deriving available custom font family names from static font files under `static/fonts/custom`.
+
+## Visual Reports
+
+`src.visual_report` owns generated research/report HTML image behavior: HTTPS Open Graph image filtering, hero images, section images, icon/logo filtering, hide/reroll client controls, and inline JSON escaping for scripts.
+
+Research routes and handler code own hidden-image persistence. Visual reports render model/source-influenced Markdown to HTML, so raw HTML/link/image sanitization remains security-sensitive.
+
+## Security Policy
+
+Media routes are cookie/current-user surfaces unless they explicitly implement token owner/scope handling. Bearer-token callers that arrive as synthetic `api` users should not be treated as owner-scoped media API clients without explicit policy.
+
+Known boundaries:
+
+- image-generation routes require `can_generate_images`;
+- image proxy/editor endpoints currently resolve client-selected, DB-selected, or fallback image model endpoints without full owner-scoped endpoint-key policy or uniform outbound revalidation;
+- generated-file serving allows rowless files and null-owner compatibility rows;
+- uploads are byte-limited and extension-gated, with content sniffing available through `UploadHandler.detect_content_type()` when `python-magic`/`libmagic` is installed;
+- several base64 JSON editor routes accept large decoded image payloads and need route-level size discipline;
+- gallery DB filenames should be joined through shared generated-media path helpers before filesystem operations;
+- editor draft source image IDs, payloads, and thumbnails are owner-scoped by draft owner but do not fully validate source-gallery ownership or payload size;
+- emoji proxy constrains codepoint filenames and degrades invalid, unknown, or unreachable SVGs to transparent no-store placeholders, but remote SVG content still deserves security review;
+- visual report Markdown HTML/link/image output needs continued sanitization coverage.
+- `scripts/mlx_image_server.py` pins generation/edit routing to the process-start model and ignores request-selected model names, preventing unauthenticated callers from selecting a local model directory/repository whose model-specific script or bridge would execute.
+
+## Degraded And Compatibility Behavior
+
+- Uploaded images record display dimensions with EXIF orientation when possible; EXIF failures warn/degrade.
+- Video uploads skip EXIF and have no metadata extraction yet.
+- Missing generated files are skipped in ZIP downloads; if all are missing, the route returns no files found.
+- Soft delete commits the gallery row state before removing the disk file, so a failed DB write does not orphan a missing image row.
+- AI tagging can fail when disk files are missing.
+- Static JS/CSS/HTML assets revalidate because there is no frontend build/versioning.
+- Gallery/editor frontend state includes stale-while-revalidate and listener cleanup to avoid stale handlers.
+- `edit_image` tool schema/implementation currently appears stale against implemented `/api/image/*` and `/api/gallery/*` routes.
+
+## Testing Coverage
+
+Existing tests cover EXIF dimensions, owner-filter helper behavior, direct upload limits, image-generation privilege source shape, sharpen auth, gallery null-user denial, endpoint SSRF/source checks, editor draft payload validation, lazy editor loading/offline precache, MLX request-model pinning, font family derivation, visual-report helper behavior, gallery CLI previews, and selected security regressions.
+
+Route-level coverage is thin for full gallery CRUD/album/tag/download/delete flows, generated-image serving, editor draft owner CRUD, signature owner CRUD, emoji proxy/cache behavior, image-tool degraded responses, optional dependency fallbacks, and frontend editor behavior.
+
+## Current Gaps
+
+- Owner-scoped endpoint-key resolution is needed for image proxy/editor routes.
+- Media routes need a clear API-token policy: reject token callers, or implement owner/scope handling.
+- Generated-image serving needs live route tests for invalid filenames, rowless files, owned rows, null-owner rows, MIME/cache headers, and cross-owner behavior.
+- Mutable generated filenames plus immutable cache headers need cache-busting tests for replace/save-over-original flows.
+- Base64 JSON editor payload size limits need hardening; upload content sniffing should keep native/Docker parity coverage as dependencies change.
+- MCP image generation needs an owner attribution decision or explicit admin-only documentation.
+- `edit_image` tool route mapping appears stale.
+- Emoji SVG proxy/cache and visual-report raw HTML/link sanitization need stronger tests.
+- Optional image dependency fallbacks are mostly untested.

+# Integrations
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers external integration surfaces in:
+
+- `routes/codex_routes.py`;
+- `integrations/codex/*` and `integrations/claude/*`;
+- `routes/api_token_routes.py` and bearer-token handling in `app.py`;
+- `routes/auth_routes.py` integration CRUD/test routes;
+- `src/integrations.py` and `data/integrations.json`;
+- canonical `routes/webhook/webhook_routes.py` plus its top-level compatibility shim, and `src/webhook_manager.py`;
+- task webhook generation/triggering in canonical `routes/task/task_routes.py`, its top-level compatibility shim, `app.py`, `static/js/tasks.js`, and `scripts/odysseus-webhook`;
+- companion/mobile pairing in `companion/routes.py` and `companion/pairing.py`;
+- provider OAuth/device-flow endpoint links in `routes/copilot_routes.py`, `routes/chatgpt_subscription_routes.py`, `routes/device_flow.py`, and `ProviderAuthSession` rows;
+- integration UI surfaces in `static/js/settings.js` and `static/js/admin.js`;
+- database models `ApiToken` and `Webhook`.
+
+The SQLAlchemy `Integration` model exists in `core/database.py`, but current Settings generic integration CRUD uses `src/integrations.py` and `data/integrations.json`.
+
+## Scoped Agent Runtime
+
+`/api/codex/*` is the canonical scoped HTTP surface for external coding agents. Claude Code uses the same runtime endpoints; `/api/claude/plugin.zip` only delivers the Claude skill bundle.
+
+`routes.codex_routes` owns:
+
+- `/api/codex/capabilities`;
+- todos list/manage through `do_manage_notes()`;
+- email list/read/draft/send;
+- memory list/add/delete;
+- calendar list/create/delete;
+- document list/read/create/delete;
+- Cookbook task/server/output/cached-model/preset/serve/adopt/stop controls.
+
+`_scope_owner()` owns scope checks and token-owner resolution. `_as_owner()` temporarily runs borrowed route handlers as the scoped owner and restores request state afterward. Borrowed email, memory, calendar, and document route handlers own their domain behavior; Codex routes only adapt them behind scoped access.
+
+Runtime behavior:
+
+- missing scopes return 403;
+- invalid payloads return 400;
+- unavailable borrowed route surfaces return 503;
+- capabilities expose scope-derived booleans and partial availability flags;
+- email send and destructive actions remain described as confirmation-required behavior in bundled agent instructions.
+- Cookbook adopt/stop paths validate stored remote SSH host and port before interpolating them into SSH commands.
+
+The local integration skill/helper files require `ODYSSEUS_URL` and `ODYSSEUS_API_TOKEN`. They must use `/api/codex/*` and must not bypass Settings/token scopes through SSH, Docker, direct DB access, local files, MCP internals, or app imports. Helper scripts refuse non-`/api/codex/*` paths.
+
+## Bundle Distribution
+
+`/api/codex/plugin.zip` ships the Codex plugin tree from `integrations/codex/`. `/api/claude/plugin.zip` ships only the Claude `skills/` subtree from `integrations/claude/skills/`. These routes require an authenticated browser/user request and do not embed an API token.
+
+Setup instructions are duplicated in integration READMEs and `static/js/settings.js`; they need to stay aligned with live route surfaces and `/api/codex/capabilities`.
+
+## API Tokens
+
+`routes.api_token_routes` owns token profiles, allowed scopes, scope normalization, token creation/update/revocation, and profile metadata shown in Settings. Partial updates preserve existing scopes unless new scopes are supplied, owner checks apply to update/delete, and write scopes auto-include their read scope where applicable.
+
+`app.py` owns bearer-token validation. It accepts `Bearer ody_...`, checks a bcrypt hash through a prefix cache, updates `last_used_at` asynchronously, and stamps:
+
+- `request.state.current_user = "api"`;
+- `request.state.api_token = True`;
+- `request.state.api_token_owner`;
+- `request.state.api_token_scopes`.
+
+The raw token is returned only on creation. Stored state is hash, prefix, owner, scopes, active flag, and timestamps. Token create/update/delete invalidates the auth middleware cache. Companion pairing also mints chat-scoped `ApiToken` rows and invalidates that cache.
+
+Current API-token consumers include:
+
+- `/api/codex/*` scoped agent routes;
+- `/api/v1/chat` synchronous external chat;
+- `/api/models` catalog reads for `chat`-scoped token owners;
+- companion read endpoints;
+- selected session and owner-attribution helpers described in `auth-security.md`.
+
+The Cookbook scoped-agent surface currently exposes `cookbook:read` and `cookbook:launch` in Settings and checks them in Codex routes; those scope names must stay reconciled with `routes.api_token_routes.ALLOWED_SCOPES`.
+
+## Generic API Integrations
+
+`src.integrations` owns generic API integration presets, `data/integrations.json`, API-key encryption/decryption, secret masking, plaintext-key migration, enabled integration prompt text, and `execute_api_call()`.
+
+`routes.auth_routes` owns admin-only HTTP CRUD/test routes for these integrations. Presets are public metadata. The ntfy test route is special: it publishes a real test notification to the configured reminder topic instead of only probing server health.
+
+`api_call` is the agent/tool execution path for configured integrations. It is blocked for non-admin/public users by tool security, accepts only relative paths, uses the admin-configured base URL/auth settings, and returns truncated external responses to the model, including a sentinel when long JSON lists are shortened. Admin-authored integration descriptions are prompt context; external responses remain untrusted data.
+
+`execute_api_call()` normalizes base URLs to HTTP(S) scheme, hostname, and
+path-only values, rejects request paths that are not relative absolute paths
+(`/...`) or that carry schemes/fragments, treats `/` as the base URL without
+appending an extra slash, and checks the final URL through `src.url_safety`.
+Link-local/metadata targets are always rejected; setting
+`INTEGRATION_API_BLOCK_PRIVATE_IPS=true` also rejects loopback/RFC1918/private
+addresses for operators who do not need LAN integrations.
+
+After validation, `execute_api_call()` pins the outbound connection to the validated IP snapshot while preserving the configured URL, Host header, TLS server name, and redirect policy. DNS cannot select a different destination between SSRF validation and transport.
+
+Current call sites include:
+
+- `src.agent_loop` injecting enabled integration descriptions;
+- `src.tool_implementations.do_api_call()`;
+- task scheduler discovery/check-ins;
+- note reminder delivery through ntfy integrations and the generic webhook reminder channel.
+
+## Webhooks And External Chat
+
+Outgoing webhooks are admin-managed `Webhook` rows. `routes.webhook_routes` owns CRUD/test/toggle/delete and `/api/v1/chat`. `src.webhook_manager` owns allowed event validation, public URL validation, delivery-time URL revalidation, DNS-rebinding-safe pinned-IP delivery, HMAC signing, fire-and-forget delivery, in-flight task references, and delivery status/error persistence. Sanitized delivery errors redact IPv6-style address details.
+
+Allowed outgoing events are:
+
+- `session.created`;
+- `chat.message`;
+- `chat.completed`;
+- `webhook.test`.
+
+Current webhook event emitters include session creation, chat message/completion paths, and `/api/v1/chat` completion.
+
+`/api/v1/chat` is an inbound external chat endpoint. It requires a `chat` API token, checks session ownership before resume, can create a session from a direct API key, and otherwise falls back to the first owner-visible enabled model endpoint. Token-supplied direct `base_url` values use public-URL validation; configured endpoints remain admin-trusted. Logs and delivery/error text that include endpoint URLs should pass through URL redaction helpers before persistence or diagnostics.
+
+## Task Webhooks And Event Triggers
+
+Task webhook triggers are separate inbound webhooks. `app.py` exempts only `/api/tasks/{task_id}/webhook/{token}` from normal auth so external callers can trigger tasks without cookies. `routes.task.task_routes` owns token generation/regeneration and validates task id, token, and active status before queueing a run; the top-level route module is a compatibility alias.
+
+`static/js/tasks.js` displays the live task webhook URL. `scripts/odysseus-webhook url` now emits the same route with percent-encoded task/token path segments; the CLI still reads and mutates task rows directly for list/show/rotate/revoke rather than delegating to HTTP route policy.
+
+Event-triggered tasks use `src.event_bus`; task execution and scheduling ownership lives in `calendar-tasks-notes.md`.
+
+## Companion Pairing
+
+`companion.routes` owns companion/mobile HTTP routes:
+
+- `/api/companion/ping`;
+- `/api/companion/info`;
+- `/api/companion/models`;
+- `/api/companion/pair`.
+
+Read endpoints accept session or bearer-token callers and resolve the effective owner for visible rows. Model responses omit API keys. Pairing `GET` renders the admin form; pairing `POST` is admin-cookie only, mints a normal chat-scoped API token, invalidates the auth token cache, and returns a host/port/token payload as HTML or JSON.
+
+`companion.pairing` owns LAN host detection, pairing payload shape, token minting, and optional QR generation. QR rendering depends on optional `qrcode`; if unavailable or failing, pairing still returns the text payload.
+
+When `COMPANION_BASE_URL` is set, pairing advertises that validated operator-selected v1 address instead of container/request auto-detection. The accepted form is a canonical ASCII `http://` LAN/Tailscale IPv4, single-label hostname, or `*.local` origin with optional valid port and no credentials/path/query/fragment; HTTPS, public/misleading numeric host spellings, percent/backslash/control characters, and unsupported hosts fail closed. Auth-disabled model inventory retains the normal single-user all-endpoints view instead of filtering every ownerless request to legacy-null rows.
+
+## Unified Settings Surface
+
+The Settings Integrations view aggregates several subsystem surfaces:
+
+- generic API integrations;
+- Codex/Claude agent token setup;
+- CalDAV, CardDAV, email accounts including Google Workspace/.edu OAuth connect flows, MCP/OAuth links, provider device-flow links, and agent tokens.
+- provider-auth backed model endpoints such as ChatGPT Subscription and Copilot, where device-flow credentials live in provider auth rows rather than endpoint API-key fields.
+
+Vault and companion/mobile setup are separate settings/route surfaces today, not entries in the unified add-integration list.
+
+This spec owns the cross-integration framing and agent/token/webhook surfaces. Domain internals stay with their subsystem specs: calendar, email/contacts, shell-MCP, vault/auth, and settings-admin.
+
+## Degraded And Compatibility Behavior
+
+- 403 from scoped APIs means a settings/scope restriction.
+- 503 from Codex borrowed routes means the domain route surface is unavailable.
+- Missing or corrupt `data/integrations.json` loads as an empty list; non-object rows are ignored.
+- Plaintext generic integration API keys migrate to encrypted storage on load.
+- Webhook delivery has no retry/backoff queue; the persisted state is last status or sanitized last error.
+- Webhook URLs are validated at create and delivery time, redirects are disabled,
+  and delivery connects to the IP set validated immediately before the request.
+- Companion LAN detection is best-effort and falls back to local host/port defaults unless a valid `COMPANION_BASE_URL` is configured.
+- `ODYSSEUS_URL` must be reachable from the external coding agent; no Docker/native URL rewrite is performed.
+
+## Security And Provenance
+
+- API-token routes must either enforce a relevant scope or document an explicit exception.
+- Codex/Claude plugin zips must not expose secrets beyond source instructions and helper files.
+- Webhook list responses expose `has_secret`, not the secret value.
+- Webhook secrets are encrypted when an API key manager is available; plaintext fallback is legacy/degraded behavior.
+- Outgoing webhook signatures use `X-Odysseus-Signature`.
+- Generic integration API keys are encrypted at rest and masked in API responses.
+- Generic integration base URLs are admin-configured and not the same public-only policy as webhook URLs.
+- `api_call` output and remote integration responses are untrusted model context.
+- Pairing payloads expose the raw chat token once through HTML/JSON/QR; persisted token storage is hash/prefix only.
+
+## Testing Notes
+
+Current targeted coverage includes API-token CRUD basics, chat-scoped `/api/models` token access, companion pairing/read-only owner scoping, webhook SSRF validation, webhook auth-exempt source checks, webhook CLI token masking, integration-store shape/encryption migration, Google email OAuth route/helper behavior, Cookbook API-token scopes, Cookbook adopt SSH host validation, and `/api/v1/chat` base-url/fallback owner scoping.
+
+The integration audit also ran the targeted venv subset covering those areas with 52 passing tests and one warning.
+
+## Current Gaps
+
+- Codex/Claude scoped routes, owner restoration, degraded 503 behavior, plugin zip contents, and helper-script path refusal need focused regression tests.
+- Token profile/update behavior and Settings agent-token scope toggles need direct coverage.
+- Codex Cookbook scopes need continued Settings, route-check, and `ALLOWED_SCOPES` regression coverage.
+- Generic integration HTTP CRUD/test routes, `execute_api_call()` auth modes, response shaping, and frontend Settings/Admin flows need direct coverage.
+- `do_manage_tokens()` does not match `/api/tokens` semantics for `ody_` prefix, owner, scopes, and cache invalidation.
+- `do_manage_webhooks()` bypasses route behavior and does not cover signing-secret parity.
+- Companion read endpoints should either require `chat` scope or be documented as an explicit scope-policy exception.
+- Decide whether webhook secret plaintext fallback should remain accepted when the API key manager is unavailable.
+- Decide whether generic integration base URLs should stay LAN-capable by default or make `INTEGRATION_API_BLOCK_PRIVATE_IPS=true` the default.
+- Admin-authored integration descriptions and `api_call` results enter the untrusted-result/gated-action pipeline, but their product-level trust presentation still needs continued review.
+- The dormant SQLAlchemy `Integration` model should be removed, migrated into use, or documented as legacy.

+# LLM Models And Endpoints
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers model/provider behavior in:
+
+- `src/llm_core.py`;
+- `src/endpoint_resolver.py`;
+- `src/foreground_model_routing.py`;
+- `src/model_discovery.py`;
+- `src/model_context.py`;
+- `src/model_capabilities.py`;
+- `src/model_capability_readers/`;
+- `src/task_endpoint.py`;
+- `src/tls_overrides.py`;
+- `src/copilot.py`;
+- `routes/copilot_routes.py`;
+- `routes/chatgpt_subscription_routes.py` and `routes/device_flow.py`;
+- `routes/model_routes.py`;
+- `routes/session_routes.py`;
+- `routes/cookbook_routes.py`, `routes/hwfit_routes.py`, and `services/hwfit/`;
+- `src/settings.py`;
+- `core/database.py` model `ModelEndpoint`;
+- frontend modules `static/js/models.js`, `static/js/modelPicker.js`, `static/js/model/matchKey.js`, `static/js/providers.js`, `static/js/settings.js`, `static/js/admin.js`, `static/js/compare/`, and Cookbook model-serving modules;
+- chat, compare, research, STT/TTS, and utility-model call sites.
+
+## Provider Calls
+
+`src.llm_core` owns provider-call mechanics. It handles OpenAI-compatible calls, Ollama normalization, Anthropic payload conversion, GitHub Copilot and ChatGPT Subscription provider detection/header injection, NVIDIA provider routing, streaming, fallback calls, upstream error formatting, async/streaming host liveness caching, configured model-list cache reads, tool-call sanitization, reasoning/thinking stream routing, and provider-specific parameter rules. GitHub Copilot OAuth/device-flow orchestration lives in `routes/copilot_routes.py` and `src/copilot.py`; ChatGPT Subscription device flow uses `routes/chatgpt_subscription_routes.py`, shared device-flow helpers, and `ProviderAuthSession` rows.
+
+`llm_core` owns payload shape. Route files and chat/agent code should request a call; they should not duplicate provider-specific payload quirks.
+
+Kimi Code User-Agent discovery has both sync and async implementations. Async
+post and stream paths probe `/models` through their existing async client and
+await each candidate, so header negotiation does not block the event loop; both
+paths share the accepted-value cache and 403 fallback policy.
+
+Provider-specific behavior is part of this layer: `LLM_CONNECT_TIMEOUT` controls the connect budget for sync and streaming calls, Kimi Code endpoints retry a small whitelisted User-Agent set on 403 and cache the accepted value, official Moonshot/Kimi Code and Anthropic Opus 4.7+ payloads omit sampling controls where required, and major-only Opus IDs such as `claude-opus-5` also omit temperature instead of falling through numeric minor-version parsing. Reasoning models omit or clamp unsupported temperature values, while self-hosted compatible endpoints keep normal parameters unless detected otherwise. Mistral structured content is normalized in async utility calls as well as stream/chat paths, and Mistral/Moonshot/Kimi reasoning content, `gpt-oss` harmony output, DeepSeek V4 thinking identifiers, and native/OpenAI-compatible Ollama thinking formats keep hidden reasoning separate from visible text. Tool names that collide with GPT-OSS built-ins are aliased on the provider boundary and mapped back before execution. Copilot request metadata remains defensive against malformed `request_flags`.
+
+## Canonical Provider And Model Shape
+
+`src.model_capabilities` owns canonical model family, task, modality,
+capability, limit, evidence, assertion, deterministic-control, probe-result,
+reasoning-control token, and display-query values.
+`src.model_capability_readers` owns endpoint-scoped stable identity, lightweight
+provider detection, record serialization, and normalization of already-fetched
+provider payloads. Readers do no network I/O. Model-specific observations are
+kept in `model-quirks.md`, not a runtime registry without a consumer.
+
+Provider support and model support are different facts. A provider may expose
+tools, reasoning, vision, or multiple APIs while individual models differ.
+Provider-native readers describe where model evidence can appear. Current
+concrete readers cover generic OpenAI-compatible identity, OpenAI, OpenRouter,
+Google, Ollama, LM Studio, and llama.cpp. Identity-only model lists remain
+unknown.
+
+Reader dispatch uses an explicit vendor first, then endpoint kind, label-bounded hostname suffix, and common local-port hints. Generic payload handling accepts `data[]`
+or `models[]` items with `id`, `name`, or `model`; it does not accept a bare
+list and never promotes capability-looking fields. Unknown fields remain in
+the in-memory raw record. See [model-capability-canonical.md](model-capability-canonical.md),
+[model-quirks.md](model-quirks.md), and the
+[provider map](model-providers/_readme.md).
+
+This canonical layer is currently exercised by focused unit tests but is not
+wired into runtime discovery, endpoint resolution, model context, request
+shaping, or frontend pickers. `routes/model_routes.py` model probes continue to
+return model IDs through their existing runtime path.
+
+Route-level probe helpers in `routes/model_routes.py` are the current exception: they build minimal provider-specific probe payloads using `llm_core` detection helpers. Keep probe behavior aligned with `llm_core` provider adapters. LLM provider HTTP clients and endpoint probes share `src.tls_overrides.llm_verify()`, which can add an operator-provided `LLM_CA_BUNDLE` on top of normal certificate verification without turning verification off or widening that trust to arbitrary URL fetches.
+
+## Endpoint Resolution
+
+`src.endpoint_resolver` owns endpoint normalization and URL construction:
+
+- base URL normalization;
+- chat and model-list URL construction;
+- endpoint ID resolution;
+- chat, utility, and vision fallback candidate selection;
+- Tailscale hostname resolution where available.
+
+OpenAI-compatible model-list URL construction preserves `/v1` bases and inserts `/v1/models` for bare local bases such as LM Studio `http://localhost:1234`.
+
+`routes/model_routes.py` owns model endpoint CRUD, admin provider discovery/probing, visible/hidden/pinned model lists, endpoint kind and refresh policy, curated/extra model partitioning, `/api/models` catalog caching, Docker loopback rewriting, tool-support probing, provider-auth linkage, endpoint-dependent settings cleanup, and owner filtering. Endpoint dedupe allows the same base URL under different API keys and surfaces API-key fingerprints/key presence without returning secrets.
+
+`routes/session_routes.py` owns binding sessions to endpoint IDs, owner-scoped header construction, raw-endpoint rejection for non-admin users, model validation, and persisted session headers. Compare panes and normal chat session creation use this path.
+
+`ModelEndpoint` rows own API keys, base URLs, cached/hidden/pinned models, model type, endpoint kind, refresh mode/interval/timeout, supports-tools state, nullable owner, optional provider-auth linkage, and provider metadata. `owner = NULL` means legacy/shared; non-null rows are private to that owner, while admins can see all. Secret fields must remain encrypted and scrubbed in responses.
+
+Decrypted endpoint headers can be copied into session metadata for chat use. Endpoint deletion must clear dependent settings and copied session headers.
+
+## Model Discovery And Lists
+
+`src.model_discovery` owns host/env/Tailscale/local-port scanning for model servers. Admin `/api/providers` and `/api/discover` use that scanner; endpoint CRUD, test, refresh, and hidden-model controls are frontend-owned by `static/js/admin.js`.
+
+`/api/models` is the normal picker/catalog surface. It is auth/owner scoped, per-user/admin-flag cached briefly, can trigger background refresh, preserves offline endpoint rows, filters hidden models, and preserves pinned model IDs for UI selection. API-token callers must carry `chat` scope and a token owner before they can list models. API/proxy endpoint inventory is visible by default until an explicit `pinned_models` allow-list is saved; an explicit empty list means show none, and legacy hidden-list state is upgraded to the equivalent pins so endpoint settings, picker checkboxes, and chat agree. Proxy/API endpoints can be marked cached-first/manual so large upstream catalogs are not repeatedly probed, while explicit refresh paths use longer manual timeouts. Local endpoints get cheap reachability probes before expensive refreshes where possible, and endpoint responses can include explicit `supports_tools` state for schema-emission heuristics. Google Gemini API endpoints use the native paginated `generativelanguage.googleapis.com/v1beta/models` catalog, send API keys in `x-goog-api-key`, retain only content-generation model IDs, and default to manual refresh unless the caller explicitly chooses another mode. Probe failure returns no curated Google fallback. `static/js/models.js` and `static/js/modelPicker.js` own the sidebar/picker catalog; `static/js/model/matchKey.js` owns longest-substring model-info/pricing key matching; `static/js/settings.js` owns default, utility, vision, image, TTS, STT, and fallback selectors.
+
+`src.task_endpoint` owns background-task endpoint/model resolution for task routes and scheduler callers. It resolves `task_endpoint_id`/`task_model` through the normal endpoint resolver with owner context.
+
+Cookbook and HWFit own local model download, serve, ranking, and auto-registration flows. They can create LLM or image `ModelEndpoint` rows, but provider dispatch remains owned by `llm_core`/endpoint resolution.
+
+## Context Length
+
+`src.model_context` owns model context-length lookup/query and token estimation. Cache keys include endpoint plus model so identical model names on different endpoints do not bleed context-window data. Unknown proxy/API models can pick up real context windows from endpoint catalog metadata such as `context_length`; otherwise unknown lengths stay explicit unknowns rather than default values. Known lengths feed chat/agent token-budget scaling through `src.context_budget`. Token estimation counts assistant `tool_calls` arguments so compaction sees tool-only turns instead of underestimating them. Chat/agent context budgeting should call this layer instead of hardcoding model windows.
+
+## Runtime Fallback And Routing
+
+`src.foreground_model_routing` owns foreground Chat/Agent fallback policy. Selected models are strict by default. Fallback requires owner-scoped `foreground_fallback_enabled=true` and an ordered `foreground_model_fallbacks` list; the old `default_model_fallbacks` setting is retired, ignored, and not migrated into consent. Named users never inherit a legacy flat/single-user fallback choice, candidate lists are capped at ten exact owner-visible models, and caller-provided allowed-model restrictions remain authoritative.
+
+Only eligible availability failures before substantive output can fall through. Default eligible statuses are 408, 425, 429, 500, 502, 503, 504, 507, 508, and 529. Missing endpoint/configuration, provider/schema/request errors, empty completions, and post-content failures do not silently change routes. A candidate commits after non-empty visible/reasoning text or a tool call; the answering route is then pinned. Foreground routing carries model and endpoint descriptors together, shapes context/compaction route-neutrally across candidates, persists only answering-route compaction, and records requested/actual/per-round route provenance plus cost attribution. Utility/background and vision fallbacks remain separate policies.
+
+Model selection has three layers: endpoint resolver hidden-model and first-chat-model selection, `/api/default-chat` per-user default/fallback resolution, and frontend picker auto-selection for empty sessions.
+
+Image routing uses model-name prefixes and `ModelEndpoint.model_type == "image"` to bypass text chat and generate media. Vision analysis uses configured vision models and `vision_model_fallbacks`; image and vision endpoint lifecycle changes should update chat, document processing, Cookbook, and settings UI together.
+
+Provider tool calls are untrusted requests, not authorization. `supports_tools` controls schema emission only; `llm_core` normalizes provider tool-call payloads, while execution authority remains in `src.tool_execution`, `src.tool_security`, and agent-tool policy.
+
+## Degraded And Platform Behavior
+
+- Provider offline or probe failures should surface actionable errors without crashing the app. Async calls retry transient 429/502/503/504 responses before failing.
+- Docker deployments may need loopback URL rewriting from `127.0.0.1` to host-accessible addresses.
+- Foreground fallback selection must preserve endpoint identity, explicit owner consent, allowed-model policy, and owner scope. User/API-token LLM dispatch that can carry configured endpoint keys must pass the effective owner into resolver calls.
+- Async and streaming calls use dead-host cooldown; sync utility/vision calls do not have identical cooldown coverage.
+- llama.cpp slot-affinity routing is local-endpoint behavior only and must not be applied to cloud/provider endpoints.
+- Hidden, pinned, cached, endpoint-kind, refresh-policy, and offline model state are UI/runtime compatibility data. Pinned models may not participate in every resolver auto-pick path unless code explicitly includes them.
+- SSE/stream parsers tolerate null choice/usage/tool-call entries and null streaming tool-call arguments; provider events should degrade to empty text or shaped stream errors instead of crashing the chat loop.
+- Provider adapters carry small model-specific quirks: Opus 4.7+ and official Kimi/Moonshot code payloads omit `temperature`, Kimi/Moonshot/Mistral reasoning content is preserved separately, ChatGPT Subscription refreshes bearer credentials, native Ollama can handle multimodal content, and Ollama `/v1` responses for Qwen3/Gemma4-style thinking can suppress thinking text when requested.
+
+## Security Policy
+
+- Endpoint API keys are encrypted in `ModelEndpoint.api_key` and never returned by endpoint APIs; admin surfaces return key presence only.
+- Endpoint CRUD, probes, provider discovery, and most endpoint configuration are admin-cookie or internal-tool gated.
+- `/api/models` is auth/owner scoped for configured deployments; API-token access requires `chat` scope and token-owner attribution.
+- Admin-created model endpoints may target local/LAN servers. Non-admin chat session creation must use registered endpoint IDs. API-token `/api/v1/chat` requires `chat` scope and validates direct `base_url` with public-only URL checks.
+
+## Current Call Sites Include
+
+- chat streaming and non-streaming calls;
+- agent loop calls with optional tool schemas;
+- compare pane calls;
+- research synthesis/probe calls;
+- utility model fallbacks for summarization/extraction;
+- frontend Settings and model picker endpoint management.
+
+## Current Gaps
+
+- Runtime provider detection, model curation, and frontend logos are still split across `llm_core`, `model_routes`, and `providers.js`; the canonical reader package has no production consumer yet.
+- Provider-specific behavior is concentrated in `llm_core.py`, which is large and easy to regress.
+- Several runtime request builders still use model-name heuristics. They should migrate only after endpoint/provider code supplies structured identity and a real consumer contract; the canonical catalog does not add a parallel quirk matcher.
+- Endpoint identity and fallback behavior need careful review when new OAuth/subscription providers are added.
+- Owner must continue to be threaded through new utility/research/default endpoint-resolution call sites so provider keys stay isolated.
+- `/api/models` owner-scoped listing/cache behavior, shared/private endpoint dedupe, endpoint-kind refresh policy, fallback-chain owner scope, and image endpoint create/list/update lifecycle need stronger route-level regression coverage.

+# Memory And Skills
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+This spec covers persistent memory and user skills in:
+
+- app wiring in `app.py` and `src/app_initializer.py`;
+- active legacy memory managers `src/memory.py` and `src/memory_vector.py`;
+- canonical memory routes in `routes/memory/memory_routes.py`, with `routes/memory_routes.py` as a compatibility shim;
+- chat memory/skill gating in `routes/chat_helpers.py`;
+- memory compatibility modules in `services/memory/memory.py`, `services/memory/memory_vector.py`, and `services/memory/service.py`;
+- provider abstractions in `src/memory_provider.py`;
+- LLM extraction/audit in `services/memory/memory_extractor.py`;
+- skill storage, format, import, and extraction in `services/memory/skills.py`, `services/memory/skill_format.py`, `services/memory/skill_importer.py`, and `services/memory/skill_extractor.py`;
+- skill routes in `routes/skills_routes.py`;
+- prompt/tool call sites in `src/chat_processor.py`, `src/agent_loop.py`, `src/ai_interaction.py`, `src/tool_implementations.py`, `src/tool_execution.py`, `src/tool_schemas.py`, and `src/tool_security.py`;
+- MCP and Codex surfaces in `mcp_servers/memory_server.py` and `routes/codex_routes.py`;
+- backup/admin/CLI surfaces in `routes/backup_routes.py`, canonical `routes/admin_wipe/admin_wipe_routes.py` plus its shim, `scripts/odysseus-memory`, `scripts/odysseus-skills`, and `scripts/odysseus-backup`;
+- frontend modules `static/js/memory.js` and `static/js/skills.js`;
+- tests under `tests/test_memory_*`, `tests/test_builtin_memory_consolidation.py`, `tests/test_skill_*`, and `tests/test_skills_*`.
+
+## Memory Runtime
+
+`src.app_initializer.initialize_managers()` creates the active `src.memory.MemoryManager` and `src.memory_vector.MemoryVectorStore` used by app startup. `routes.memory.memory_routes` imports through `services.memory` but is passed the startup manager instances; top-level `routes.memory_routes` is a `sys.modules` compatibility shim.
+
+`MemoryManager` owns JSON-backed memory storage in `data/memory.json`, validation, owner fields, pinned state, use counts, and text/keyword similarity. Read-only `load_all()` remains lenient and can degrade an unreadable store to no memories. Mutating read-modify-write paths use `load_all_for_update()`, which raises `MemoryStoreUnreadable` rather than letting a corrupt or unreadable file be overwritten with an empty list. Agent/MCP/native-provider adds, extraction, backup import, and owner migration preserve that distinction; legacy `memory.txt` migration remains allowed. `MemoryVectorStore` owns semantic lookup when Chroma and embeddings are reachable.
+
+Chat memory behavior:
+
+- chat preferences and incognito state gate memory preface use;
+- pinned memories are loaded for the owner;
+- retrieved memories use keyword matching plus optional vector scoring;
+- inserted memory is wrapped as untrusted context;
+- memory use counts are incremented after insertion.
+
+`services/memory/memory_extractor.py` owns LLM-assisted extraction, audit, and validation flows. It requests model behavior and writes through the memory manager; it does not own chat session persistence.
+
+Extraction handles reasoning-model response shapes and records explicit dislike/drop preferences as `dislikes` rather than losing them to generic fact handling.
+
+## Skills Runtime
+
+`services/memory/skills.py` owns disk-backed skill storage under `data/skills/<category>/<name>/SKILL.md`, plus `_usage.json` usage/audit sidecars. Legacy `data/skills.json` is a read-only fallback/import source, not the current write shape.
+
+`services/memory/skill_format.py` owns frontmatter/body parsing and emission. Quoted scalar parsing/emission is symmetric: JSON escapes decode once, UTF-8/non-ASCII stays intact, emitted values escape line separators safely, and invalid JSON-style escapes fall back to literal text instead of compounding backslashes on every save. `services/memory/skill_importer.py` resolves public GitHub/skills URLs, fetches bundle files with strict public-network URL safety, and chooses/imports `SKILL.md`. Import disables automatic redirects, follows at most five hops, validates and resolves each hop, then connects only to the validated IP snapshot through a pinned transport while preserving URL, Host, and TLS identity; GitHub final-host checks and file/size limits still apply. `routes/skills_routes.py` owns CRUD/search/index/import, owner filtering, skill test/audit jobs, and admin-gated built-in tool instruction overrides.
+
+Skill extraction is owned by `services/memory/skill_extractor.py`. It can suggest or save skills from conversations, tries valid brace-delimited JSON candidates with `JSONDecoder.raw_decode()`, rejects ambiguous multiple top-level JSON objects instead of guessing, and saved skills remain user-editable data.
+
+Agent skill behavior:
+
+- matched skills are owner-scoped, confidence-gated, usage-counted, and wrapped as untrusted context;
+- `index_for()` exposes published skills plus teacher-escalation drafts gated by platform and toolsets; `active_toolsets=None` means the caller has no explicit toolset knowledge and does not hide `requires_toolsets` skills, while an explicit list applies the gate;
+- user prefs such as skills enabled, auto-approve, and max injected skills shape runtime insertion;
+- the level-0 base skill index currently calls `index_for(owner=None)`, so it is not fully owner-scoped.
+- skill tests use the configured utility model rather than the chat default and wrap user-editable skill text as untrusted context; approval continuation for a test or teacher-generated skill uses the same exact-action gate as the normal agent loop.
+
+## Tools, MCP, And Backup
+
+Native `manage_memory` and `manage_skills` tool paths pass owner context and use in-process policy gates. `manage_skills` requires an explicit action instead of silently defaulting a malformed call. Manual memory add can choose a category, and route-side manual add validates the source session owner before attaching session-derived memories. `mcp_servers/memory_server.py` lazy-initializes `src` managers and exposes list/add/edit/delete/search. It can scope to `ODYSSEUS_MCP_MEMORY_OWNER` or `ODYSSEUS_MEMORY_OWNER`; if the JSON store contains owner-bearing entries and no owner env is configured, it returns an owner-scope error instead of listing or mutating across owners. Ownerless stores remain ownerless compatibility mode.
+
+The direct `odysseus-memory add` CLI tolerates non-object legacy/corrupt rows
+when checking whether its newly added entry is already present; it ignores
+those rows instead of calling mapping methods on them and crashing the add.
+
+`/api/export` owner-filters memories and skills. `/api/import` imports skills through current disk-backed `SkillsManager` APIs, stamping missing owners to the importer and preserving supported skill metadata. Full data snapshots through `scripts/odysseus-backup` preserve on-disk skill trees, memory JSON, and caches differently from JSON import/export.
+
+## Compatibility State
+
+Memory and skills are partially migrated:
+
+- app startup, MCP, and some tools still use `src.memory*`;
+- services memory modules remain relevant for imports/tests, with memory and vector modules re-exporting canonical `src` implementations;
+- `services/memory/service.py` is a compatibility facade around the canonical managers, but it remains ownerless and should not be assumed equivalent to route/tool owner policy;
+- skills are service-owned and disk-backed, while backup import and some compatibility paths still expect older JSON/list shapes.
+
+## Degraded Vector Memory
+
+Chroma is an external HTTP service. Native defaults use `localhost:8100`; Docker uses `chromadb:8000`. Embeddings prefer configured HTTP endpoints and can fall back to local FastEmbed.
+
+Startup can degrade to keyword-only memory when vector initialization fails. Extraction/audit paths catch vector failures and continue with text/JSON behavior. Vector dedup is checked against the current owner before suppressing a candidate, and audit rebuilds preserve other owners' vector rows. Chat retrieval assumes a healthy startup vector store remains usable, so post-start vector failures can still break memory retrieval unless handled by the caller.
+
+Admin wipe currently has a vector cleanup compatibility gap because it imports a nonexistent helper before attempting vector clearing.
+
+## Policy
+
+Saved memories and skills are untrusted source data when shown to the model. A stored skill may contain useful instructions, but it is still user-editable content and must be framed consistently with prompt-injection policy.
+
+Owner isolation is surface-specific:
+
+- HTTP memory and skills routes are expected to owner-filter normal user data;
+- native memory/skill tools are expected to pass owner context;
+- Codex exposes scoped token memory behavior separately;
+- normal memory/skills routes are cookie/current-user surfaces, not scoped token APIs;
+- MCP memory uses an environment-configured owner for owner-scoped stores, while the agent level-0 skill index currently has ownerless/global behavior;
+- vector dedup during memory extraction suppresses only same-owner or legacy-ownerless vector matches.
+
+Skill test/audit flows intentionally run user-editable `SKILL.md` content as instructions inside controlled jobs. Those jobs rely on route owner checks, admin gates where applicable, and tool execution policy.
+
+Skill import is admin-gated defense-in-depth, but imported URLs are still untrusted network input. Initial and redirected targets must remain public, automatic redirects stay disabled, and the connection must use only the IP set validated for that hop so DNS rebinding cannot change the destination between validation and transport.
+
+User rename flows update skill frontmatter owner fields and `_usage.json` owner keys alongside memory/upload/research ownership migrations.
+
+## Testing Coverage
+
+Existing tests cover memory extraction/degraded vectors, owner isolation, unreadable-store mutation refusal, MCP memory shape/scope, skill owner update/delete, prompt-injection wrapping and approval continuation, utility-model selection, toolset gating, frontmatter escape round trips, skill-import redirect and DNS-rebinding/SSRF defenses, CLI non-object rows, and selected route owner checks.
+
+Route-level memory CRUD/security, skills route security, MCP memory behavior, vector degraded writes, compatibility facade owner behavior, backup skill import, admin vector cleanup, and frontend endpoint wiring need broader coverage.
+
+## Current Gaps
+
+- `services/memory/service.py` needs an explicit owner-scope/support decision before it is treated as a public memory API.
+- The agent level-0 skill index should thread owner or be documented as an intentional local/global index.
+- MCP memory still needs a deliberate multi-user UX/config decision, but current behavior avoids cross-owner access when owner-bearing rows exist without an explicit MCP owner env.
+- Memory JSON import does not rebuild vector indexes.
+- Admin wipe vector clearing is currently ineffective.
+- Chat memory retrieval needs a graceful path for vector failures after startup.
+- Route-level memory and skills security coverage is incomplete.

+# Canonical Provider And Model Capability Layer
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers the implementation introduced on current `dev` in:
+
+- canonical model values and query helpers in `src/model_capabilities.py`;
+- record, identity, and provider-detection helpers in
+  `src/model_capability_readers/base.py`;
+- reader dispatch in `src/model_capability_readers/__init__.py`;
+- concrete readers for generic OpenAI-compatible, OpenAI, OpenRouter, Google,
+  Ollama, LM Studio, and llama.cpp payloads;
+- regression coverage in `tests/test_model_capabilities.py` and
+  `tests/test_model_capability_readers.py`.
+
+The layer normalizes already-fetched JSON-compatible values. It performs no
+network I/O, does not shape provider requests, does not persist its output, and
+does not authorize model or tool use. No production caller currently consumes
+the canonical records outside this package; runtime integration remains later
+work.
+
+There is no `src/provider_capability_schemas.py`, capability-specific
+diagnostics module, or runtime model-quirk registry on current `dev`.
+
+## Layer Boundaries
+
+- `src.model_capabilities` defines normalized families, tasks, modalities,
+  capabilities, evidence sources/confidence, assertion states, deterministic
+  controls, probe results, reasoning-control tokens, and display-surface
+  queries.
+- `ModelCapability` owns family, primary task, input/output modalities,
+  capability tokens, limits, source, and confidence.
+- `CapabilityAssertion` records claimed, verified, unsupported, or unknown
+  status for one capability. Missing evidence is not an unsupported claim.
+- `DeterministicControl` records support evidence for controls such as
+  temperature, top-p, seed, tool choice, or prompt caching. A supported
+  request control is not itself a model capability.
+- `CapabilityProbeResult` is an in-memory evidence shape that converts pass,
+  fail, or partial probe state into an assertion. No current runtime probe
+  stores or merges these objects.
+- `CapabilityQuery` and `display_surfaces_for()` map a normalized capability
+  into candidate surfaces such as chat, vision chat, image generation,
+  embeddings, or reranking. They are not wired into current pickers.
+- Reader `ModelCapabilityRecord` binds a vendor/model identity to the nested
+  capability object, assertions, deterministic controls, and optional raw
+  provider evidence.
+
+Provider transport support and per-model support are separate facts. Request
+and response adapters remain in `src.llm_core` and related provider modules.
+Model-specific observations remain in [model-quirks.md](model-quirks.md).
+
+## Current Serialized Shapes
+
+`ModelCapability.to_dict()` emits the nested capability shape:
+
+```json
+{
+  "family": "chat",
+  "primary_task": "chat.completions",
+  "modalities": {
+    "input": ["text", "image"],
+    "output": ["text"]
+  },
+  "capabilities": ["tool_call", "vision"],
+  "limits": {"context_tokens": 131072},
+  "source": "provider_reader",
+  "confidence": "provider_reported"
+}
+```
+
+`ModelCapabilityRecord.to_dict()` wraps that value with `vendor`, `model_id`,
+`stable_model_id`, `display_name`, `capability_assertions`, and
+`deterministic_controls`. It does not currently emit a schema version or the
+flat `provider`/`model`/`features`/`controls` shape. Raw provider fields are
+included only when the caller passes `include_raw=True`.
+
+Endpoint configuration can explicitly map `model_type=llm` to chat and
+`model_type=image` to image generation. Missing or unrecognized endpoint types
+stay unknown rather than silently becoming chat-capable in this schema layer.
+
+## Identity And Reader Dispatch
+
+`records_from_payload()` selects a reader from an explicit `vendor`, or from
+`detect_vendor(base_url, endpoint_kind)` when no vendor is supplied.
+
+Current detection order and behavior are:
+
+1. a recognized explicit endpoint kind;
+2. label-bounded hostname checks for OpenRouter, OpenAI, Anthropic, Google APIs, and Ollama Cloud;
+3. common local ports: `11434` for Ollama, `1234` for LM Studio, `8000` for vLLM, and `30000` for SGLang;
+4. generic OpenAI-compatible for any other parsed host, otherwise unknown.
+
+These are normalization hints, not authorization. Hostname checks accept an exact domain or its dot-delimited subdomains after lowercasing and removing a trailing dot, so names such as `notopenai.com` do not match `openai.com`; local-port mappings remain intentionally covered by tests. Callers must not treat any result as proof of endpoint trust.
+
+Implemented reader modules are `generic_openai`, `openai`, `openrouter`,
+`google`, `llamacpp`, `ollama`, and `lmstudio`. Anthropic, Hugging Face,
+SGLang, and vLLM have placeholder vendor IDs but currently dispatch through the
+generic identity-only reader. Other explicitly supplied vendor strings are
+also preserved while using that generic reader.
+
+Stable model identity is scoped in this order:
+
+- explicit endpoint ID;
+- a short hash of normalized base URL when an endpoint ID is absent;
+- `global` when neither endpoint identity is supplied.
+
+## Generic Identity-Only Contract
+
+The generic reader accepts mapping payloads containing `data[]` or `models[]`.
+Each item must itself be a mapping and provide `id`, `name`, or `model`.
+Bare-list payloads and `key`/`slug`-only items are not accepted by the current
+implementation.
+
+The reader deliberately returns unknown family, modalities, capabilities, and
+controls. It preserves the raw item on the in-memory record but does not parse
+type/task fields, descriptions, ownership, supported-parameter lists,
+capability-looking booleans, or token limits.
+
+## Provider-Native Readers
+
+- OpenAI keeps the official Models API identity-only.
+- OpenRouter maps explicit architecture modalities, supported parameters,
+  limits, voices, and default parameters into family/capability/control state.
+- Google maps the native Models resource. Embedding-only methods map to the
+  embedding family; content-generation methods do not prove modality or chat
+  family. Explicit thinking, limits, sampling fields, caching, and batch
+  methods are retained without parsing product names.
+- Ollama treats `/api/tags` as identity-only and maps selected-model
+  `/api/show` capability tokens. Context can come from structured fields or a
+  parsed `num_ctx` line in the serialized `parameters` value.
+- LM Studio maps native v1 `models[]` and v0-style `data[]` fields. A plain
+  OpenAI-compatible list without native type/capability fields stays unknown.
+- llama.cpp can merge `/v1/models`, `/props`, and `/slots` evidence for one
+  served model. It records tool/streaming claims, explicit unsupported
+  vision/audio assertions, controls, and runtime/training/size limits.
+
+Readers tolerate non-object entries and unknown fields where their helpers
+permit it. They do not infer authoritative capability from model IDs or display
+names.
+
+## Evidence Semantics
+
+The canonical vocabulary includes admin override, endpoint configuration,
+provider reader, Cookbook/Hugging Face, maintained registries, heuristic,
+probe, and unknown sources. It also defines explicit, provider-reported,
+registry, heuristic, and unknown confidence values.
+
+Those tokens make evidence representable; current `dev` does not implement a
+global precedence, merge, expiry, or conflict-resolution engine. Assertions
+generated by readers are usually `claimed`; a `CapabilityProbeResult` maps pass
+to verified, fail to unsupported, and partial to claimed at the scope carried
+by that object.
+
+## Tests
+
+Focused tests pin:
+
+- endpoint-kind, host, and common-port vendor detection;
+- endpoint/base-URL-scoped stable IDs;
+- unknown behavior for generic and official OpenAI lists;
+- canonical normalization and display-surface matching;
+- assertion, deterministic-control, and probe-result shapes;
+- OpenRouter, Google, Ollama, LM Studio, and llama.cpp mappings;
+- negative cases that avoid name-based media/capability inference.
+
+## Current Gaps
+
+- Canonical records are not yet used by runtime discovery, endpoint resolution, model context, request shaping, or frontend pickers.
+- Reader output is not persisted, refreshed, merged, or expired.
+- Provider detection still uses common-port hints; consumers must not promote normalization hints into trust decisions.
+- Only seven concrete readers exist; placeholder and other providers use the
+  identity-only generic reader.
+- Generic fallback does not accept bare-list or `key`/`slug`-only payloads.
+- There is no capability-specific diagnostic/logging path.
+- Runtime request builders still contain model-name heuristics outside this
+  canonical layer.

+# Provider Capability Specs
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This directory maps serving-provider observations and current model-catalog
+normalization into the canonical layer defined by
+[model-capability-canonical.md](../model-capability-canonical.md). It records
+current Odysseus implementation evidence, merged fixes, reproducible user
+observations, and provider documentation without treating any single source as
+global model truth.
+
+## General To Specific Resolution
+
+Read specs in this order:
+
+1. [openai-compatible.md](openai-compatible.md) for the conservative general
+   identity-only reader;
+2. the serving-provider file for native endpoints, headers, request/response
+   observations, and catalog fields;
+3. [model-quirks.md](../model-quirks.md) for model-specific observations.
+
+Provider files document transport; runtime adapters still own it. Model quirks
+record only deviations and are not a second runtime matcher. Shared model facts
+must not be copied into every provider file. An OpenAI-compatible provider is
+not OpenAI: an explicitly supplied vendor string is preserved even when it uses
+the generic reader.
+
+Current reader dispatch does not infer a provider from payload shape. It uses an explicit vendor, then endpoint kind, label-bounded hostname matches, and common local-port hints. The port hints map 11434 to Ollama, 1234 to LM Studio, 8000 to vLLM, and 30000 to SGLang. Those hints are normalization behavior, not endpoint trust.
+
+## Provider Map
+
+### Implemented canonical readers
+
+- [openai.md](openai.md): identity-only Models API plus Chat/Responses dialects.
+- [openai-compatible.md](openai-compatible.md): generic compatible catalog and runtime dialect boundaries.
+- [openrouter.md](openrouter.md): rich architecture, modalities, parameters, and limits.
+- [google.md](google.md): native paginated Gemini Models API and GenerateContent.
+- [ollama.md](ollama.md): `/api/tags`, `/api/show`, native chat, and OpenAI compatibility.
+- [lm-studio.md](lm-studio.md): native v1 catalog/chat, explicit v0 compatibility, and OpenAI compatibility.
+- [llama-cpp.md](llama-cpp.md): `/props`, `/slots`, OpenAI/Responses/Anthropic surfaces.
+
+### Placeholder identities using the generic reader
+
+- [anthropic.md](anthropic.md): identity-only Models API and native Messages runtime adapter.
+- [vllm.md](vllm.md): common-port identity hint; deployment capability remains unknown.
+- [sglang.md](sglang.md): common-port identity hint; parser/config-dependent capability remains unknown.
+- [hugging-face.md](hugging-face.md): Hub observations and download/fit metadata without a canonical reader.
+
+### Provider observations without a dedicated canonical reader
+
+- [mistral.md](mistral.md): rich model cards, reasoning controls, and structured runtime content.
+- [github-copilot.md](github-copilot.md): account model-list observations and required runtime headers.
+- [chatgpt-subscription.md](chatgpt-subscription.md): Codex model identity and Responses event shape.
+- [cohere.md](cohere.md): native endpoint/catalog observations; not currently normalized.

+### Other local/proxy serving identities
+
+- [local-compatible-engines.md](local-compatible-engines.md): MLX LM, TGI,

+
+## Provider Spec Template
+
+Each provider file records:
+
+- provider identity and API dialects;
+- latest observed native catalog endpoint/envelope and capability-bearing fields;
+- whether current source has a dedicated reader or only generic fallback;
+- observed request, tool, text, reasoning, and control paths owned by runtime
+  adapters rather than the catalog reader;
+- what remains per-model/unknown;
+- Odysseus evidence and regressions;
+- fallback/safety behavior and current gaps.
+
+Marketing capability lists and curated picker lists may guide research but do
+not automatically become model claims. Provider-returned false values can be
+negative evidence only at the same provider/endpoint/model scope.

+# Anthropic Provider Shape
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+Canonical placeholder vendor ID `anthropic`; Anthropic Messages runtime
+adapter in `src/llm_core.py`. There is no dedicated Anthropic capability-reader
+module; explicit/auto-detected Anthropic payloads use the generic identity-only
+reader.
+
+## Catalog Shape
+
+`GET /v1/models` returns `data[]` model resources with `id`, `type: model`,
+`display_name`, and `created_at`, plus pagination metadata. These fields prove
+identity/availability only. Do not assume all listed Claude models share
+vision, tools, reasoning, sampling, or context limits.
+
+## Request And Response Shape
+
+Native Messages uses a top-level `system`, alternating `messages`, content
+blocks, `tools[].input_schema`, `tool_use` assistant blocks, and `tool_result`
+user blocks. Text, thinking, signatures, server-tool blocks, and tool calls are
+typed content rather than OpenAI roles/fields. Preserve block IDs/signatures
+needed for continuation.
+
+Sampling and thinking support can be version/model specific. The Opus 4.7+ sampling omission is a model-scoped runtime observation, not an Anthropic-wide rule. Runtime version parsing accepts explicit major/minor IDs and later major-only IDs such as `claude-opus-5`, treats a missing minor as `.0`, caps both components so date stamps cannot be misread as versions, and keeps legacy Claude 3 Opus sampling intact. Anthropic-compatible proxies are Anthropic dialect only when configured or their exact payload/endpoint shape proves it (#3110).
+
+## Fallback And Safety
+
+Runtime and canonical reader detection use label-bounded Anthropic host matching or an explicit endpoint kind. A provider using Anthropic Messages through another host must be explicit. Identity-only model cards remain unknown.
+
+## Current Gaps
+
+- The public model list does not provide per-model canonical capability data.
+- There is no dedicated Anthropic canonical reader; only `id`, `name`, or
+  `model` identity survives generic normalization.
+- Runtime model-version parsing needs structured identity before a later
+  consumer can centralize sampling exceptions without another name matcher.

+# Atlas Cloud Provider Shape
+
+Last updated: dev@28d27ee | 2026-07-17
+
+## Scope
+
+Canonical provider ID `atlas_cloud`; OpenAI-compatible provider proposed in
+#5566 with live `/v1/models` observations for current Qwen/DeepSeek offerings.
+
+## Shape
+
+Treat the observed list as identity-only. Even capability-looking item fields
+remain raw until an Atlas-specific discriminating shape intentionally maps
+them. The model IDs observed by a PR demonstrate availability at that time,
+not permanent capability or a reason to hardcode family-name behavior.
+
+## Fallback And Current Gaps
+
+Exact Atlas Cloud host or explicit kind preserves identity; otherwise use the
+inventory fallback. The provider work is open/unmerged and has no independently
+versioned rich catalog schema, so evidence remains provisional.

+# Azure OpenAI Provider Shape
+
+Last updated: dev@28d27ee | 2026-07-17
+
+## Scope
+
+Canonical provider ID `azure_openai`; Azure deployment-scoped OpenAI dialects;
+custom endpoints use explicit configuration.
+
+## Shape
+
+Azure commonly identifies deployments rather than globally stable model IDs.
+Preserve endpoint, deployment ID, API version, and underlying model/version as
+separate structured identity when returned. A standard OpenAI-compatible model
+list is identity-only until an Azure-specific reader intentionally maps its
+deployment fields.
+
+Request paths and authentication can be deployment/API-version specific; do
+not blindly append public OpenAI paths or copy provider quirks. Capability and
+limits are deployment scoped.
+
+## Fallback And Current Gaps
+
+Known `*.openai.azure.com` hosts select Azure OpenAI; other Azure gateways need
+explicit kind. Odysseus lacks a native Azure deployment catalog reader and
+structured API-version persistence in the canonical record.

+# AWS Bedrock Provider Shape
+
+Last updated: dev@28d27ee | 2026-07-17
+
+## Scope
+
+Canonical provider ID `bedrock`; UI/provider mapping currently recognizes AWS
+Bedrock, but the canonical layer has no native Bedrock runtime reader.
+
+## Shape
+
+Bedrock is not generally an OpenAI-compatible host: model IDs, inference
+profiles, request/response unions, signing, and per-family payloads differ.
+Only an explicitly configured OpenAI/Anthropic-compatible gateway may use those
+dialects. Native Bedrock capability must come from a versioned Bedrock model
+catalog plus exact foundation-model/inference-profile identity.
+
+## Fallback And Current Gaps
+
+Do not classify all `amazonaws.com` hosts as Bedrock; use explicit kind or a
+future region-aware exact host/path shape. General fallback is safe only behind
+an explicitly compatible gateway. Native signing, catalogs, and family payload
+mappings remain unimplemented.

+## Scope

+Canonical provider ID `cerebras`; OpenAI-compatible cloud transport; runtime

+
+## Shape And Observations
+
+Model lists use the general identity-only inventory reader. Cerebras rejects
+llama.cpp-only `session_id` and `cache_prompt` fields (#4640), so cloud identity

+# ChatGPT Subscription Provider Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Canonical provider ID `chatgpt_subscription`; Codex Responses transport;
+auth and runtime code in `src/chatgpt_subscription.py`,
+`routes/chatgpt_subscription_routes.py`, and `src/llm_core.py`.
+There is no dedicated ChatGPT Subscription canonical reader on current `dev`.
+
+## Catalog Shape
+
+The account-scoped Codex models endpoint returns root `models[]`; `slug` is the
+request identity and `visibility`/`priority` control availability/order. These
+fields do not prove tools, reasoning, vision, or context. Null/malformed model
+lists fail soft rather than crashing discovery (#5280/#5281).
+
+The canonical generic reader does not accept `slug`-only items, so this runtime
+catalog is not currently normalized into `ModelCapabilityRecord` values.
+
+## Request And Response Shape
+
+Transport uses a ChatGPT backend Responses endpoint, `input` items, flattened
+function tools, streamed function-call argument events, exact `call_id`, and
+`function_call_output` continuation. Parallel calls and encrypted reasoning
+continuity require preserving typed output/history rather than coercing all
+roles to text. This shape is supported by the existing adapter and the focused
+tool-calling follow-up evidence in #5490; unmerged observations remain claimed
+until integrated/reproduced.
+
+OAuth/device credentials and refresh are provider-session behavior. Expired
+credentials should return an actionable reconnect error, not generic model
+failure.
+
+## Fallback And Safety
+
+Only the explicit internal base/ChatGPT host selects this provider. Never send
+subscription credentials to a custom OpenAI-compatible URL. Catalog slugs stay
+identity-only unless account-scoped fields or probes supply capability.
+
+## Current Gaps
+
+- Comprehensive Responses tool/reasoning parity is still evolving.
+- Account model slugs are not consumed by the canonical reader package.
+- The account catalog does not currently provide a complete canonical
+  capability card for every slug.

+# Cohere Provider Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Documented provider identity `cohere`; native Chat v2 plus the OpenAI
+Compatibility API. Current `dev` has no dedicated Cohere capability reader or
+direct Cohere request adapter; compatible endpoints use the general runtime
+path when explicitly configured.
+
+## Catalog Shape
+
+`GET /v1/models` returns a paginated `models[]` envelope. Each model can carry
+`name`, `endpoints`, `default_endpoints`, `context_length`, `features`, and
+`sampling_defaults`; the root can carry `next_page_token`.
+
+These are candidate fields for a future dedicated reader:
+
+- a single canonical family from `endpoints`: `chat`/`generate`, `embed`,
+  `rerank`, or `classify`;
+- `context_length` to the endpoint/model context limit;
+- known sampling-default keys to deterministic controls.
+
+Current canonical normalization does not map them. When the generic reader is
+explicitly selected with vendor `cohere`, it preserves only item identity plus
+the raw item; family, context, features, and sampling controls stay unknown.
+
+## Request And Response Shape
+
+Native `POST /v2/chat` uses `messages`, structured content blocks, tools,
+`response_format`, sampling fields, and an optional structured `thinking`
+object. Text lives in `message.content[type=text].text`; reasoning-capable
+models use `message.content[type=thinking].thinking`. Streaming uses typed
+events rather than one generic text delta.
+
+The OpenAI compatibility base is `/compatibility/v1`. Its current chat subset
+includes tools, structured output, sampling, and `reasoning_effort`, but model
+support remains per-model. In the compatibility dialect only `none` and `high`
+currently map to native thinking off/on; do not assume low/medium support.
+
+## Fallback And Safety
+
+No Cohere host or payload-shape detection exists in the canonical reader
+registry. The caller must supply provider/endpoint configuration. Marketing
+pages and provider-wide endpoint features do not grant every listed model
+tools, vision, or reasoning.
+
+## Evidence And Gaps
+
+- Official List/Get Models resources define the catalog fields.
+- Official Chat v2, Reasoning, and Compatibility API resources define the
+  transport and thinking controls.
+- Odysseus has no direct Cohere request adapter, canonical reader, or sanitized
+  canonical fixtures yet; both normalization and runtime integration remain
+  follow-up work.

+# DeepSeek Provider Shape
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+Canonical provider ID `deepseek`; official cloud OpenAI-compatible API;
+curation/detection in `routes/model_routes.py` and runtime reasoning handling in
+`src/llm_core.py`.
+
+## Shape And Observations
+
+Use the general model-list inventory shape; capability-looking fields remain
+unknown until a DeepSeek-native reader maps them. Cloud response history can use
+`reasoning_content`; preserve it structurally for reasoning turns and tool
+continuation (#968, #3152). `deepseek-chat`, reasoning models, distilled local
+variants, and future V4 models do not share one capability record.
+
+Cloud endpoint evidence can support tools while a local DeepSeek-R1 deployment
+may not have a working tool parser. Existing tool-support tests intentionally
+separate official host from local engine/model-name heuristics.
+
+Current runtime thinking-pattern detection includes DeepSeek V4 identifiers so their structured reasoning channel is handled like the other supported DeepSeek reasoning families. This name-level compatibility rule is not canonical capability evidence and does not make every V4-labelled local deployment tool-capable.
+
+## Fallback And Current Gaps
+
+Exact `*.deepseek.com` selects provider identity; self-hosted checkpoints use
+Ollama/vLLM/SGLang/llama.cpp identity. Curated model IDs and pricing/context
+tables are compatibility data, not authoritative capability. A rich official
+model-card reader is still absent.

+# GitHub Copilot Provider Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Canonical provider ID `copilot`; OpenAI-compatible chat with Copilot headers
+and OAuth; runtime adapter `src/copilot.py` and routes in
+`routes/copilot_routes.py`. There is no dedicated Copilot canonical reader on
+current `dev`.
+
+## Catalog Shape
+
+The observed Copilot `/models` response uses `data[]` entries with:
+
+- `id`;
+- `model_picker_enabled`;
+- `capabilities.supports.tool_calls` and `.vision`;
+- optional limit/family metadata.
+
+Runtime model discovery uses picker state for availability. The canonical
+reader package does not map the nested support fields; an explicitly supplied
+`copilot` vendor currently uses generic identity-only normalization, and
+`model_picker_enabled` does not become canonical capability.
+
+## Request And Response Shape
+
+Chat is OpenAI-compatible but requires Copilot/GitHub API version, editor/plugin
+identity, intent, integration, and initiator headers; image requests add the
+vision request flag. Header derivation must tolerate malformed message entries.
+OAuth token exchange and access policies are provider authentication, not model
+capability.
+
+## Fallback And Safety
+
+Use exact GitHub Copilot host or explicit kind, including the constrained
+enterprise `copilot-api.*.ghe.com` form. Do not treat arbitrary `ghe.com` hosts
+as Copilot. Official model availability tables are useful registry context but
+do not replace the account-scoped catalog response.
+
+## Current Gaps
+
+- The catalog shape is implementation-observed and needs ongoing fixture
+  comparison with current Copilot clients.
+- Copilot catalog capability fields are not normalized by current `dev`.
+- Account/plan/policy availability must remain endpoint-user scoped.

+# GitHub Models Provider Shape

+
+## Shape
+
+Use general identity-only inventory. Deployment IDs and account access
+can differ from upstream model IDs. Do not copy Copilot picker metadata,

+# Google Gemini Provider Shape
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+Canonical provider ID `google`; native GenerateContent plus optional Google
+OpenAI-compatible chat; readers `google.py` and
+`google_ai_studio_mapping.py`; catalog/probe ownership in
+`routes/model_routes.py`.
+
+## Catalog Shape
+
+Use the native paginated `GET /v1beta/models` endpoint, including
+`nextPageToken`, with `x-goog-api-key` when configured. `models[]` can contain:
+
+- `name`, `baseModelId`, `version`, and `displayName`;
+- `inputTokenLimit` and `outputTokenLimit`;
+- `supportedGenerationMethods`;
+- `thinking`, `temperature`, `maxTemperature`, `topP`, and `topK`.
+
+Embedding-only methods map to embedding. Generation methods prove a native
+method, not chat/image/video/audio modality, so those records remain unknown
+unless stronger structured evidence exists. `thinking: true` and explicit
+sampling fields map to a reasoning claim and controls. Model IDs such as
+Imagen, Veo, or TTS names are not parsed.
+
+## Request And Response Shape
+
+Native generation uses `contents`, `systemInstruction`,
+`generationConfig`, `tools[].functionDeclarations`, and
+`models/{model}:generateContent|streamGenerateContent`. Responses use
+`candidates[].content.parts[]` for `text`, `functionCall`, `functionResponse`,
+`thought`, and `thoughtSignature`; token accounting is in `usageMetadata`.
+Native Google tool/thought continuity must not be flattened through an
+OpenAI-only history shape.
+
+## Fallback And Safety
+
+Prefer native model metadata even when chat is configured through Google's
+OpenAI compatibility URL. Pagination parameters must remain stable between
+pages. The route probe activates only for the exact
+`generativelanguage.googleapis.com` hostname, filters the picker list to
+content-generation methods, returns no curated fallback after probe failure,
+and defaults those endpoints to manual catalog refresh unless explicitly
+overridden. The canonical Google reader is not yet called by that probe.
+Unknown methods and fields stay raw; unrecognized prediction models remain
+unknown.
+
+## Current Gaps
+
+- The Models resource does not expose full modalities for every Google media
+  family.
+- Native Gemini request/response support is not yet the only runtime path.

+
+## Scope
+
+Canonical provider ID `groq`; OpenAI-compatible cloud transport; detection and
+request behavior in `src/llm_core.py`.
+
+## Shape
+
+Model discovery falls back to the general `data[].id` identity shape. Richer

+supply modalities, supported parameters, or limits. Groq transport may accept OpenAI-style tools and streaming extensions,

+

+that is transport compatibility, not a provider-wide model capability claim.
+
+## Fallback And Current Gaps
+
+Exact `*.groq.com` preserves Groq identity. Do not infer Llama/Gemma model
+capabilities from IDs. There is no canonical rich Groq model-card reader or

+# Hugging Face Provider And Registry Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Canonical placeholder vendor ID `huggingface`; download/fit metadata in
+`services/hwfit/`; OpenAI-compatible inference providers/TGI handled as their
+serving dialect. There is no dedicated Hugging Face canonical reader on
+current `dev`.
+
+## Hub Model Shape
+
+Hub model info can provide `modelId`/`id`, `pipeline_tag`, `tags`, `config`, and
+card metadata. Current canonical normalization does not map `pipeline_tag`,
+`config.model_type`, or Hub task/modality fields. An explicitly selected
+Hugging Face vendor uses generic identity-only normalization.
+
+This source is `cookbook_hf`/registry confidence, not live endpoint truth.
+Free-form tags, README/card prose, repository names, and architecture names do
+not automatically claim capability. A serving engine can load a model with
+missing projection, different template, or disabled parser.
+
+## Serving Shape
+
+Hugging Face routed inference and TGI can expose OpenAI-compatible endpoints;
+their model list may be identity-only. Keep Hub identity separate from the
+serving endpoint and merge only when exact revision/model identity is known.
+
+## Fallback And Safety
+
+Hub metadata can fill a scoped registry record after provider payload fields
+and probes, but must not overwrite fresh endpoint-negative evidence. Treat
+remote code, model cards, and repository files as untrusted content.
+
+## Current Gaps
+
+- Revision/digest linkage between downloads, Hub records, and serving
+  endpoints is incomplete.
+- Hub task/family metadata is not consumed by the canonical reader package.
+- Pipeline tags can be missing or overly broad; unknown stays unknown.

+compatibility plus native server metadata; reader
+`src/model_capability_readers/llamacpp.py`.
+
+## Metadata Shapes
+
+`/v1/models` provides served identity and can include server model entries;
+native `/props` is authoritative for the running model/server combination:
+
+- `model_alias`/`model_path`;
+- `default_generation_settings.n_ctx` and sampling `params`;
+- `total_slots` and optional `/slots[].n_ctx` fallback;
+- `chat_template_caps` for tools/system role;
+- `modalities.vision|audio`;
+- current server/build state.
+
+Capability depends on weights, projection/model assets, chat template, parser,
+and launch flags. It is endpoint evidence, not a checkpoint-name claim.
+`/props` and `/v1/models` can be merged only for the same served identity.
+
+## Request And Response Shape
+
+llama-server supports several OpenAI-compatible tasks and native extensions.
+Do not infer embeddings/rerank/chat solely from the OpenAI model card; use an
+explicit server model capability field or endpoint configuration. Tool and
+reasoning correctness can depend on selected chat template and parser.
+
+## Fallback And Safety
+
+The registry selects llama.cpp through an explicit vendor or endpoint kind; it
+does not auto-detect `/props` from payload shape. Port 8000 currently maps to
+the vLLM placeholder, while 8080 falls through to generic OpenAI-compatible.
+llama.cpp-only `session_id` and `cache_prompt` affinity fields must remain local
+endpoint behavior and never leak to strict cloud providers (#4640 and current
+affinity tests).
+
+## Current Gaps
+
+- Multi-model routing requires per-served-model `/props` association.
+- Parser/template configuration is not yet fully represented in canonical
+  endpoint metadata.

+# LM Studio Provider Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Canonical provider ID `lmstudio`; native LM Studio v1 plus OpenAI Chat and
+Responses compatibility; reader `src/model_capability_readers/lmstudio.py`.
+
+## Catalog Shapes
+
+Preferred shape is `GET /api/v1/models` with root `models[]`. Current fields
+include `key`, `type` (`llm` or `embedding`), display/publisher data,
+`architecture`, quantization/format/size, `max_context_length`,
+`loaded_instances[].config.context_length`, and a capability object containing
+`vision`, `trained_for_tool_use`, and reasoning options/defaults.
+
+Compatibility shape `GET /api/v0/models` uses `data[]` with `id`, `type`
+(`llm`, `vlm`, or embeddings), `arch`, `compatibility_type`, state, and
+context metadata. It is an explicit older shape, not a loose fallback.
+OpenAI `/v1/models` is identity-only when native endpoints are unavailable.
+
+Loaded-instance context is the effective runtime context; maximum context is a
+separate limit. Model type maps family, explicit capability booleans map
+vision/tools/reasoning, and architecture is provider-reported model family.
+
+## Request And Response Shape
+
+Native v1 chat is `/api/v1/chat` and can expose stateful/MCP-oriented output;
+LM Studio also supports OpenAI Chat and Responses compatibility. Keep dialect
+selection explicit because tool/MCP features differ between native and
+compatible paths.
+
+## Fallback And Safety
+
+Current reader detection identifies port 1234 as LM Studio. Prefer pathless
+native `/api/v1/models` discovery where configured (#1122, #3615), then v0,
+then general identity. The port mapping is a normalization hint, not endpoint
+trust. An error object from an unsupported native route is not a model list.
+
+## Current Gaps
+
+- Runtime discovery does not yet persist native capability records.
+- LM Studio API capabilities continue to evolve; each new native version needs
+  an explicit shape fixture before promotion.

+# Other Local And Proxy Compatible Engines

+Last updated: dev@28d27ee | 2026-07-17
+
+## Scope
+
+Canonical explicit identities `mlx_lm`, `text_generation_inference`,
+`lmdeploy`, and `litellm`, plus unknown OpenAI-compatible deployments not
+covered by the native Ollama, LM Studio, llama.cpp, vLLM, or SGLang specs.
+
+## Shape
+
+Use explicit endpoint kind when known; otherwise use only the general model
+list envelopes for inventory identity. Capability-looking structural fields
+remain raw. Local host and port do not distinguish these engines.
+MLX/Cookbook launch recipes, TGI task configuration, LMDeploy
+adapters, and LiteLLM upstream routing can all change capability independently
+of the model ID.
+
+Proxy model aliases are endpoint scoped. A proxy may return richer fields, but
+unknown keys remain raw until a versioned shape is added. Provider-specific
+headers/extensions must not be applied based on a port or upstream model name.
+
+## Fallback And Safety
+
+Discovery can probe cheap native identity endpoints when available, but
+capability probes execute only explicit bounded test contracts. Never read
+broad server/environment dumps as ordinary model metadata. Unknown compatible
+servers should still list identities and make conservative text calls where
+explicitly configured, without appearing on capability-gated surfaces.
+
+## Current Gaps
+
+- These engines need individual safe metadata fixtures before they can graduate
+  from general fallback.
+- Gateway upstream identity and effective downstream model capability are not
+  yet represented as a chain.

+# MiniMax Provider Shape
+
+Last updated: dev@28d27ee | 2026-07-17
+
+## Scope
+
+Canonical provider ID `minimax`; international host `api.minimax.io`, China
+host `api.minimaxi.com`; current OpenAI-compatible and recommended
+Anthropic-compatible text transports. Odysseus contains MiniMax-oriented tool
+output handling and local-serving guidance but no dedicated catalog reader.
+
+## Catalog Shape
+
+Current `GET /v1/models` is an OpenAI-compatible identity list:
+`object: list`, `data[]`, and model cards containing `id`, `object: model`,
+`created`, and `owned_by: minimax`. The `owned_by` discriminator identifies the
+provider shape, but the card exposes no per-model capability or modality
+fields. Keep these records unknown and preserve raw identity metadata.
+
+Do not backfill current model capabilities, token limits, or modalities from
+the platform overview into this list response. Those tables are useful scoped
+registry evidence only after model/version identity and freshness are carried
+explicitly.
+
+## Request And Response Shape
+
+- OpenAI compatibility uses `/v1/chat/completions` and structured
+  `reasoning_content` alongside normal message content.
+- Anthropic compatibility uses `/anthropic/v1/messages`; the current M2.7
+  family supports typed thinking blocks and interleaved thinking, making this
+  the preferred reasoning/tool-continuation transport in provider guidance.
+- Native audio, image, video, music, and file endpoints are separate product
+  shapes. They must not be inferred from presence in the text model list.
+
+## Local Deployments
+
+The current provider guide documents vLLM, SGLang, and MLX deployment. Those
+instances retain serving-engine identity and configuration-derived capability;
+the checkpoint name alone does not turn a vLLM/SGLang card into the hosted
+MiniMax provider shape.
+
+## Fallback And Current Gaps
+
+Exact MiniMax hosts or the discriminating `owned_by: minimax` model-list shape
+select provider identity. Unknown compatible proxies retain the general shape.
+The identity list does not safely distinguish M2 reasoning behavior from
+speech/image/video/music products, so exact model quirks remain documentation
+until structured model-version evidence reaches runtime request builders.

+# Mistral Provider Shape
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+Canonical provider ID `mistral`; OpenAI-compatible chat with Mistral response
+extensions and runtime handling in `src/llm_core.py`. There is no dedicated
+Mistral canonical reader on current `dev`.
+
+## Catalog Shape
+
+`GET /v1/models` returns `data[]` cards with `id`, `root`, aliases,
+`max_context_length`, and `capabilities` booleans including
+`completion_chat`, `completion_fim`, `function_calling`, `vision`,
+`classification`, and lifecycle/fine-tuning fields. These are candidate fields
+for a future dedicated reader:
+
+- chat/FIM or classification family;
+- vision input;
+- function calling;
+- explicitly reported reasoning/structured output when present;
+- context limit and root family.
+
+Fine-tuning availability and archived status are not inference capabilities.
+The current generic reader retains identity/raw data only and does not map any
+of these fields. Different Mistral models retain independent identities.
+
+## Request And Response Shape
+
+Reasoning-capable models accept graded `reasoning_effort`. Mistral can return `content` as typed blocks: a `thinking` block containing text fragments plus a normal `text` block. Runtime normalizes those blocks for async utility calls as well as chat/stream paths, keeping reasoning and visible text separate instead of stringifying the list or scanning text tags (#4698, #5882).
+
+## Fallback And Safety
+
+Runtime `llm_core` detects label-bounded Mistral hosts for request/response
+handling. The canonical registry has no Mistral host or rich-payload detector;
+an explicitly supplied `mistral` vendor falls back to generic identity. A
+Mistral model served through another engine uses that serving engine's dialect.
+
+## Current Gaps
+
+- Catalog reasoning fields vary across model-card generations; absent remains
+  unknown.
+- Mistral catalog capability fields are not normalized by current `dev`.
+- Runtime thinking-family selection still uses names and should migrate to
+  structured root/capability identity.

+## Scope

+Provider IDs `moonshot` for official Moonshot API and `kimi_code` for the Kimi
+Code surface; OpenAI-compatible transport with provider-specific headers and
+model-specific behavior in `src/llm_core.py`.
+
+## Shape And Observations
+
+Model lists use the general OpenAI-compatible identity shape unless a richer
+account response is returned. Official Kimi K2.5/K2.6 fixes temperature by
+thinking mode, so Odysseus omits `temperature` rather than sending an invalid
+value (#3960). Thinking tool-call continuation requires preservation of
+assistant `reasoning_content` (#3118). Kimi Code negotiates a small exact
+User-Agent set on 403 and caches the accepted value; this is provider transport,
+not model capability.
+
+Reports distinguish K2.5/K2.6 multimodality from older K2 variants (#2522).
+Promote those claims only through exact structured model IDs/families, not a
+`kimi` name match.
+
+## Fallback And Current Gaps
+
+Keep Moonshot and Kimi Code identities distinct even when both use OpenAI Chat.
+Self-hosted Kimi checkpoints inherit their serving engine shape, not official
+Moonshot sampling rules. The provider catalog does not yet yield a complete

+
+Model lists use the general identity-only shape; capability-looking fields

+# Ollama Provider Shape
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+Canonical provider ID `ollama`; native Ollama chat/generate plus OpenAI
+compatibility; reader `src/model_capability_readers/ollama.py`; discovery and
+runtime code in `routes/model_routes.py` and `src/llm_core.py`.
+
+## Catalog And Detail Shapes
+
+Use two native steps:
+
+1. `GET /api/tags` returns `models[]` identity (`name`/`model`, digest,
+   `details.family|families`, format, parameter size, quantization). Tags do not
+   claim capabilities.
+2. `POST /api/show` for a selected model returns explicit `capabilities[]`,
+   `details`, and `model_info`. Map completion/chat, embedding, vision, tools,
+   and thinking/reasoning tokens. Map context from exact `context_length` or
+   native `<architecture>.context_length` fields.
+
+The reader does not parse model names or architecture names. It does parse a
+two-column serialized `parameters` value and can take `num_ctx` from it before
+falling back to exact or suffix `*.context_length` keys in structured mappings.
+The parameters text is used only for that keyed limit lookup, not capability
+inference.
+
+## Request And Response Shape
+
+Native chat uses `/api/chat`, `messages`, optional OpenAI-shaped tool
+definitions, `format`, `options`, and model-dependent `think`. Responses use
+`message.content`, `message.thinking`, and `message.tool_calls`. Generate uses
+top-level `response` and `thinking`. OpenAI compatibility is a separate dialect
+and can change control names independently.
+
+Manual Ollama endpoints registered against the OpenAI-compatible `/v1` surface default to text/prompted tools unless the operator explicitly enables `supports_tools`; model naming alone does not opt that dialect into native function schemas.
+
+Thinking control is model-specific: most documented reasoning families accept
+a native bool, while GPT-OSS accepts low/medium/high and cannot be fully
+disabled. A reported Ollama 0.20.6 Qwen3.5 OpenAI-compat path requires
+`reasoning_effort: none` rather than `think: false` (#5503); keep it versioned
+and low-confidence until corroborated.
+
+## Fallback And Safety
+
+Current reader detection identifies port 11434 as Ollama, in addition to an explicit endpoint kind or an exact/label-bounded `ollama.com` hostname. This is a normalization hint, not endpoint trust or capability evidence. Names that contain `vision`, `embed`, or `qwen` are not capability evidence (#3743, #4487).
+
+## Current Gaps
+
+- List discovery needs an orchestrated `/api/show` detail step per model.
+- Runtime OpenAI-compat thinking suppression still contains name heuristics.

+# General OpenAI-Compatible Inventory Fallback
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+Canonical compatibility identity `generic_openai`; identity-only reader
+`src/model_capability_readers/generic_openai.py`; shared envelope and identity
+helpers in `src/model_capability_readers/base.py`.
+
+This is not a universal OpenAI-compatible capability schema. Transport request
+and response behavior remains in `src.llm_core` and provider adapters.
+
+## Accepted Inventory Shape
+
+- `{"data": [...]}`;
+- `{"models": [...]}`.
+
+Within an item, the reader recovers identity from `id`, `name`, or `model`.
+Bare-list payloads and `key`/`slug`-only items are not supported. It preserves
+the raw item on the in-memory record, while `to_dict()` includes it only when
+the caller explicitly requests `include_raw=True`. Capability remains unknown.
+
+## Disabled Capability Paths
+
+The generic reader does not inspect capability-looking fields, including:
+
+- `type`, `model_type`, `task`, and `pipeline_tag`;
+- top-level or nested modality fields;
+- capability booleans/maps/lists;
+- `supported_parameters`;
+- context, input, output, and model-length fields.
+
+Names, descriptions, ownership, pricing, and serialized text also never
+promote capability through this reader.
+
+## Forward Compatibility
+
+An explicitly configured but unknown provider ID is preserved when the generic
+reader is selected. That allows endpoint-scoped stable IDs to keep working
+while every family, modality, capability, limit, and control remains unknown.
+Non-object entries are skipped; null or malformed roots return no records.
+
+Provider-specific headers, request extensions, and reasoning channels must be
+selected by explicit provider/endpoint adapters. They never leak through this
+fallback.
+
+Compatible tool-call syntax is likewise a runtime concern rather than catalog capability. Current parsers recover selected Hermes/Qwen JSON bodies nested inside `tool_call` wrappers and require the full Qwen bare end delimiter; GPT-OSS compatibility can alias names that collide with its built-in tools and reverse that alias before local dispatch. None of those repairs grants execution authority or proves generic tool support.
+
+## Current Gaps
+
+- Compatible providers differ on path prefixes, null handling, tools,
+  streaming usage, and strict extra-field rejection.
+- Bare-list and `key`/`slug`-only inventories need explicit normalization if a
+  runtime consumer later requires them.
+- Safe request shaping still requires explicit endpoint/provider
+  configuration even when identity normalization succeeds.

+# OpenAI Provider Shape
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+Canonical provider ID `openai`; API dialects OpenAI Chat Completions and
+Responses; catalog reader `src/model_capability_readers/openai.py`.
+
+## Catalog Shape
+
+`GET /v1/models` returns `object: list` with `data[]` model cards containing
+`id`, `object`, `created`, and `owned_by`. This is identity and availability
+metadata only. It does not claim vision, tools, reasoning, modality, task, or
+context length. The record remains unknown and keeps the raw fields.
+
+## Request And Response Shape
+
+Chat uses `messages`, `tools[].function`, `tool_choice`, and
+`choices[].message|delta`; Responses uses `input`, flattened tools, output
+items, and typed stream events. OpenAI may support a parameter at the platform
+level while individual models differ. A later model registry or probe must
+scope that fact before it becomes canonical model capability.
+
+## Fallback And Safety
+
+An explicit endpoint kind selects this provider. Automatic reader detection accepts exact `openai.com` or a dot-delimited subdomain after normalizing case/trailing dots; it is a normalization hint rather than a trust boundary. Do not parse model IDs or ownership labels. If a proxy returns richer fields while explicitly configured as OpenAI, the reader preserves them as raw evidence but keeps capability unknown.
+
+## Current Gaps
+
+- OpenAI's Models API does not publish the per-model capability shape needed
+  for automatic canonical classification.
+- Runtime model-specific sampling/reasoning behavior still needs a maintained
+  structured registry or endpoint probes.

+# OpenCode Provider Shape
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+Canonical provider identity `opencode` with Zen/Go endpoint variants; OpenAI-compatible transport and webhook presets in `src/llm_core.py` and canonical `routes/webhook/webhook_routes.py`, with the top-level route module retained as a compatibility shim.
+
+## Shape
+
+Keep Zen and Go path identity in endpoint metadata even though the canonical
+provider family is OpenCode. Model discovery uses general identity-only
+fallback. Path/version, account policy, and model selection can differ between
+variants; do not flatten them into OpenAI.
+
+## Fallback And Current Gaps
+
+Exact `*.opencode.ai` plus configured `/zen` or `/zen/go` selects this family.
+No provider-specific rich capability catalog is mapped, and runtime still has
+separate variant labels that should eventually become structured endpoint
+metadata.

+# OpenRouter Provider Shape
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+Canonical provider ID `openrouter`; OpenAI-compatible chat dialect; rich reader
+`src/model_capability_readers/openrouter.py`.
+
+## Catalog Shape
+
+`GET /api/v1/models` returns `data[]`. Canonical fields are:
+
+- `id` (falling back to `name`) and display `name`;
+- `architecture.input_modalities`, `architecture.output_modalities`, and
+  compatibility `architecture.modality`;
+- `context_length` and `top_provider.max_completion_tokens`;
+- `supported_parameters`, `default_parameters`, `supported_voices`, and
+  `per_request_limits`.
+
+Modalities determine family and vision/file/audio/image/video behavior.
+Recognized supported parameters claim tools, JSON/structured output,
+reasoning, and web search. Sampling/default parameters become controls, not
+capabilities. Descriptions, pricing, author slugs, and tokenizer names do not.
+
+## Provider Versus Routed Endpoint
+
+OpenRouter normalizes requests while routing a model to one of several
+underlying providers. The catalog model record is OpenRouter-scoped. Do not
+copy a direct-provider quirk to OpenRouter unless its normalized API and exact
+model/endpoint evidence require it. `top_provider` limits describe the current
+route class, not a permanent global model limit.
+
+## Fallback And Safety
+
+The reader receives OpenRouter through explicit selection or an exact/label-bounded `openrouter.ai` hostname hint. Future fields remain raw. If modalities are absent, it falls back to an identity-only OpenRouter record and does not parse the model slug; supported-parameter controls are not retained on that fallback path.
+
+## Current Gaps
+
+- Per-upstream endpoint differences can still invalidate an aggregate claim.
+- Catalog values change frequently and need freshness/expiry when persisted.

+# SGLang Provider Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Canonical provider ID `sglang`; OpenAI Chat/Responses plus native generation;
+Cookbook launch behavior in `routes/cookbook_routes.py` and serving UI modules.
+There is no dedicated SGLang canonical reader on current `dev`.
+
+## Metadata Shapes
+
+Preferred native `GET /model_info` (legacy `/get_model_info`) returns:
+
+- `model_path` and `tokenizer_path`;
+- `is_generation`;
+- `has_image_understanding` and `has_audio_understanding`;
+- `model_type`, `architectures`, `weight_version`;
+- `preferred_sampling_params`.
+
+These are provider observations for a future dedicated reader. Current generic
+normalization does not map `is_generation`, modality booleans, sampling keys,
+or `max_model_len`.
+
+`GET /v1/models` returns served IDs with `owned_by: sglang`, `root`, and
+`max_model_len`; it supplies identity/context but not parser capability.
+
+## Runtime Capability
+
+Tools and reasoning depend on explicit `--tool-call-parser` and
+`--reasoning-parser`; multimodality and context can also be launch-configured.
+Cookbook recipes for Qwen, DeepSeek, GLM, Kimi, MiniMax, StepFun, and other
+families are deployment observations, not universal model-name rules. Persist
+the selected parser/config as endpoint evidence before canonical promotion.
+
+## Fallback And Safety
+
+Current reader detection identifies port 30000 as SGLang, or accepts an
+explicit endpoint kind, then dispatches to the generic identity-only reader.
+It does not infer SGLang from `/model_info` payload shape. Avoid normal
+discovery through the broad admin `/server_info` dump.
+
+## Current Gaps
+
+- Endpoint records do not yet store parser/task configuration canonically.
+- Non-generation task classification needs explicit serving metadata.
+- No dedicated reader maps SGLang metadata today.

+
+## Scope
+
+Canonical provider ID `together`; OpenAI-compatible cloud transport; curated
+models and discovery compatibility in `routes/model_routes.py`.
+
+## Shape And Observations
+
+Together has returned both standard `data[]` and bare model-card lists. The
+current generic reader accepts the standard envelope when the caller supplies
+the Together vendor, but it does not accept a bare root list. It keeps
+identity/provider scope and promotes no capability fields. Task, modality,
+parameter, and limit data needs a dedicated Together reader before it becomes
+canonical; model names and the curated picker list are not capability evidence.
+
+Together can serve many upstream families. Direct-provider quirks do not
+automatically apply because Together may normalize requests and responses.
+
+## Fallback And Current Gaps
+
+Both `*.together.xyz` and `*.together.ai` identify the provider. Malformed/null
+lists fail soft. A provider-specific rich capability schema has not been
+confirmed, so general fallback remains intentional. Bare-list catalogs require
+route-specific preprocessing or a future reader update.

+# vLLM Provider Shape
+
+Last updated: dev@e57f60b | 2026-07-20
+
+## Scope
+
+Canonical placeholder provider ID `vllm`; OpenAI Chat and Responses serving;
+generic identity-only inventory normalization. There is no dedicated vLLM
+reader or model-card detector on current `dev`.
+
+## Catalog Shape
+
+Current `GET /v1/models` returns `object: list`, `data[]` model cards with
+`id`, `object`, `owned_by: vllm`, `root`, `parent`, `max_model_len`, and
+`permission[]`. The generic reader retains only identity/raw data and does not
+inspect `owned_by`, `root`, `parent`, `max_model_len`, or `permission`. The card
+does not prove chat template, tools,
+reasoning parser, vision assets, embeddings, transcription, or rerank.
+
+LoRA cards can use a different `id`, root path, and parent. Keep each served ID
+endpoint scoped and do not merge it globally with the base checkpoint.
+
+## Runtime Capability
+
+vLLM's supported API surface is broad, but actual behavior depends on the
+loaded model task, chat template, multimodal assets, tool-call parser,
+reasoning parser, structured-output configuration, and launch flags. Current
+Odysseus reasoning regressions cover structured `reasoning`, legacy
+`reasoning_content`, and compatible fields (#602). These response channels are
+transport evidence, not a claim that every vLLM model reasons.
+
+## Fallback And Safety
+
+Current reader detection identifies port 8000 as vLLM, or accepts an explicit
+endpoint kind, then dispatches to the generic identity-only reader. It does not
+infer vLLM from the model-card payload. Do not consume `/server_info`
+environment/config dumps for normal discovery because they can be large and
+operationally sensitive.
+
+## Current Gaps
+
+- A small safe native capability endpoint is not part of the canonical probe.
+- Deployment parser/template flags are not persisted with endpoint capability.
+- No dedicated reader maps vLLM model-card fields today.

+# Model Behavior Observations
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+This file records model- or provider+model-specific behavior observed in
+Odysseus code, tests, Issues, PRs, commits, and provider documentation. It is a
+compact evidence map, not a runtime matcher. General canonical rules belong in
+[model-capability-canonical.md](model-capability-canonical.md); provider-wide
+transport belongs in [the provider map](model-providers/_readme.md).
+
+The canonical capability layer intentionally has no
+`src/model_behavior_quirks.py`.
+Adding a registry before runtime call sites carry structured provider, model,
+version, and dialect identity would create another model-name matching layer.
+
+## General Observation Template
+
+Record only the fields supported by the evidence:
+
+- provider and endpoint/dialect scope;
+- exact provider-returned model ID or family;
+- structured model/provider version when available;
+- capability or request/response behavior observed;
+- exact native request field/value and response field when relevant;
+- source, confidence, status, and reproduction date;
+- whether the behavior is already implemented in runtime code.
+
+If exact structured identity is unavailable, keep the observation here and in
+its current tested runtime location. Do not promote it through substring,
+regex, prose, or serialized-prompt parsing in the canonical layer.
+
+## Model-Specific Observation Map
+
+| Observation | Scope | Behavior | Evidence/status |
+| --- | --- | --- | --- |
+| Moonshot Kimi K2.5/K2.6 fixed temperature | official Moonshot, K2.5/K2.6, OpenAI Chat | omit `temperature`; thinking mode owns its fixed value | #3960, `f5d3e509`; implemented in current runtime |
+| Moonshot reasoning tool history | same provider/models/dialect | preserve assistant `reasoning_content` across tool continuation | #3118, `2e6fff22`; implemented |
+| Claude Opus 4.7+ sampling omission | Anthropic Messages, Opus 4.7+ and major-only later IDs such as `claude-opus-5` | omit `temperature`, `top_p`, and `top_k` where the runtime rule applies | #3117, `4f48cfa9`, #5761; implemented through current runtime identity logic |
+| Mistral structured reasoning | reasoning-capable Mistral model through native/compatible response shape | use graded effort where accepted; keep typed thinking separate from text | #4698, `bd9149f7`, provider docs; partly implemented |
+| Ollama native reasoning control | selected reasoning model/deployment | native `think`; reasoning in `message.thinking`/`thinking` | #3031 and provider docs; deployment scoped |
+| Ollama native `gpt-oss` reasoning level | `gpt-oss` served through Ollama native | `think` accepts low/medium/high and does not represent off | provider docs; deployment scoped |
+| Ollama compatibility disable observation | Ollama 0.20.6+, observed Qwen3.5 compatibility path | `reasoning_effort: none` was reported to disable reasoning | #5503; unmerged/low confidence until reproduced |
+
+Issue and commit references are evidence identifiers, not runtime dependencies.
+Open or unmerged observations remain provisional until reproduced or supported
+by current provider documentation.
+
+## Other Model-Level Observations
+
+- Kimi K2.5/K2.6 multimodality differs from older K2 variants (#2522). Promote
+  only from an exact provider card or scoped registry, never the `kimi` token.
+- Google product names suggest media tasks to humans, but its Models resource
+  does not publish complete modalities. Keep those modalities unknown without
+  stronger model-scoped evidence.
+- Ollama `/api/tags` names can omit vision markers (#3743, #4487). Use selected
+  model `/api/show.capabilities`, not its name.
+- Local reasoning controls vary by serving template/config: message/system
+  directives, `chat_template_kwargs.enable_thinking`, native booleans,
+  structured objects, budgets, and effort levels were all observed (#3031).
+  These are endpoint/deployment facts, not universal checkpoint properties.
+- DeepSeek, vLLM/NIM, Mistral, Moonshot, Ollama, and harmony-style servers use
+  different structured reasoning channels. Provider/dialect evidence chooses
+  the channel; generic response-text scanning is not capability discovery.
+- Current runtime recognizes DeepSeek V4 identifiers in its thinking-model patterns; that is request/response handling evidence, not proof that every V4-named endpoint exposes identical capabilities.
+- GPT-OSS deployments can reserve native tool names. Runtime aliases colliding Odysseus tool names at the provider boundary and reverses the alias before local execution; this is dialect compatibility, not extra tool authorization.
+- Cohere native and compatibility transports expose different thinking
+  controls/channels. The Cohere model list does not itself prove reasoning.
+- MiniMax M2.7 exposes different thinking channels through Anthropic and
+  OpenAI-compatible transports. Its current model list is identity-only.
+- Gemma/Phi/Qwen vision behavior has changed across serving engines (#1430,
+  #1704, #1478). Native engine metadata or a verified endpoint probe outranks
+  a model-family name list.
+
+## Promotion Gate
+
+Before an observation becomes canonical runtime behavior, a consumer must
+already have the necessary structured identity and tests must cover both its
+positive scope and a neighboring negative scope. Request control and response
+visibility remain separate: hiding reasoning text is not the same as disabling
+reasoning at the provider (#2905).
+
+## Current Gaps
+
+- Runtime still contains model-name helpers for several implemented behaviors;
+  this spec records them but the canonical catalog does not duplicate them.
+- Hosted aliases and provider behavior can change; there is no durable
+  observation expiry/revalidation layer yet.
+- Detail/probe-only model facts cannot safely be populated from list discovery.

+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers durable state in:
+
+- `core/database.py`;
+- `src/database.py`;
+- `src/runtime_paths.py`;
+- `src/constants.py`;
+- `core/models.py`;
+- `core/session_manager.py`;
+- `core/atomic_io.py`;

+- JSON stores managed by `core/auth.py`, `src/settings.py`, `src/api_key_manager.py`, `src/preset_manager.py`, `src/integrations.py`, `src/upload_handler.py`, `src/personal_docs.py`, `src/research_handler.py`, `src/bg_jobs.py`, `routes/prefs_routes.py`, canonical `routes/contacts/contacts_routes.py` and `routes/vault/vault_routes.py` plus their shims, `routes/cookbook_routes.py`, and memory/skills managers;
+- `routes/email_helpers.py` scheduled-email storage;
+- `routes/backup_routes.py` and `scripts/odysseus-backup`;
+- runtime data under `data/`.
+
+## Database Shape
+
+`core/database.py` owns SQLAlchemy models and startup migrations. `src/database.py` is a compatibility re-export for legacy imports. Route and service code commonly owns its own `SessionLocal()` lifecycle instead of using one central unit-of-work wrapper.
+
+The default database is SQLite at `DATA_DIR/app.db`. `src.runtime_paths` and `src.constants` own the data-dir default: source runs use the repository `data/` directory, frozen builds default to `~/.odysseus/data`, and `ODYSSEUS_DATA_DIR` overrides both. SQLAlchemy can point at a non-SQLite `DATABASE_URL`, but current startup migrations/backfills are SQLite-first and often use `sqlite3`, `PRAGMA`, or SQLite catalog queries. External DBs are not fully migration-compatible unless those helpers are made backend-neutral.
+
+After `Base.metadata.create_all()`, `init_db()` resolves file-backed SQLite
+paths from SQLAlchemy's parsed engine URL and attempts to restrict the main
+database plus existing `-journal`, `-wal`, and `-shm` sidecars to `0600` on
+POSIX. Driver-qualified, query-tagged, and local `file:` URI forms are covered;
+non-SQLite, in-memory SQLite, and Windows paths are skipped. A failed POSIX
+chmod is logged because the database and sidecars can contain password/token
+hashes and encrypted provider material.
+
+Timestamp defaults use `utcnow_naive()` so existing naive `DateTime` columns stay UTC without the deprecated `datetime.utcnow()` default.
+
+Current model families include:
+
+- chat sessions, messages, and `chat_messages_fts` transcript-search state/triggers;
+- documents and document versions;
+- gallery albums/images, editor drafts, signatures, generated-media metadata;
+- email accounts, model endpoints, MCP servers, comparisons;
+- provider auth sessions for OAuth/device-flow-backed provider credentials;
+- API tokens, admin-global webhooks, user tools/tool data, integrations;
+- crew members, scheduled tasks, task runs, notes;
+- memory rows, calendar calendars, and calendar events.
+
+Chat persistence stores model-readable text plus compact attachment-reference
+lines in `chat_messages.content`, while structured references remain in message
+metadata. Provider data URLs used by the live turn are not duplicated into the
+durable transcript. The FTS migration recreates insert/update triggers to omit
+inline media and scrubs legacy indexed rows that still contain data URLs.
+
+Current calendar/task persistence includes CalDAV remote identity columns (`CalendarCal.remote_href`, `CalendarCal.remote_etag`, `CalendarEvent.remote_href`, `CalendarEvent.remote_etag`), `CalendarEvent.caldav_sync_pending` for retryable writeback state, and `ScheduledTask.character_id` for built-in task persona selection.
+
+`EmailAccount` includes encrypted password fields plus Google OAuth fields (`oauth_provider`, encrypted access/refresh tokens, token expiry) and optional `display_name`. Startup migrations add those OAuth/display columns idempotently for older databases.
+
+Email default-account state is serialized per owner. Startup normalizes legacy duplicate defaults and installs a per-owner unique default constraint/index; create, delete/promotion, set-default, demo teardown, and user rename perform their default transition in one locked transaction. Multi-owner rename locks are acquired in canonical order, so a stale concurrent default mutation fails closed instead of recreating multiple defaults.
+
+`core/models.py` owns pure dataclasses used by `SessionManager`. It does not own database persistence.
+
+`routes/email_helpers.py` owns a second SQLite database at `data/scheduled_emails.db` for scheduled email, summary, reply, tag, sender-signature, urgency-alert, calendar-extraction, and cache state. Its migrations and owner backfills are local to that module, not `core/database.py`, and those auxiliary tables are owner-scoped.
+
+## Migration Policy
+
+Odysseus does not use Alembic. `core.database.init_db()` runs at module import, before FastAPI lifespan startup. `Base.metadata.create_all()` creates missing tables; hand-written `_migrate_*` functions add or reshape legacy columns.
+
+Runtime behavior:
+
+- migrations must be idempotent;
+- SQLite foreign keys are enabled for every engine connection;
+- new SQLAlchemy columns need matching startup migration code;
+- legacy ownerless/shared rows may exist and must be handled by owner-aware route helpers.
+
+Startup backfills include document-owner backfill from linked sessions, blanket legacy owner assignment for SQL and selected JSON stores, `user_prefs.json` per-user nesting, email account seeding from legacy settings, and encryption rewrites for legacy plaintext endpoint, signature, and email secrets. Failed encryption rewrites are logged and retried on later startup.
+
+Owner-claiming is partly automatic and partly manual. `core.database._migrate_assign_legacy_owner()` assigns many ownerless SQL rows and selected JSON records to the primary admin when auth data exists, while `scripts/claim_ownerless.py` is an explicit local utility for claiming older ownerless memories, skills, sessions, documents, gallery rows, and comparisons.
+
+## Ownership And Access
+
+Owner columns are security-relevant. Current owner-bearing domains include sessions, documents, gallery images/albums, editor drafts, model endpoints, signatures, API tokens, user tools/tool data, comparisons, crew members, scheduled tasks/task runs, memories, notes, calendars/events, email accounts, and integrations. Webhooks are admin-global today and do not have an owner column.
+
+Route code owns filtering for its domain. `src.auth_helpers.owner_filter()` is the common helper where available; gallery, documents, calendar, email, skills, and other surfaces also use local filters. Null-owner compatibility is domain-specific: shared endpoints may include null owners, while strict gates and disk stores may reject them. Do not rely on frontend filtering for access control.
+
+`src.owner_identity` defines the storage-only Default/Local owner `__odysseus_local__`. `effective_storage_owner()` maps an absent caller to it only when auth is explicitly disabled, preserves named owners, and rejects request sentinels; `storage_owner_for_request()` also resolves bearer tokens to their real owner. This is a new canonical contract, not a completed migration. SQL `NULL` and missing JSON owners still usually mean legacy/shared/unscoped compatibility; older route dependencies can return `""`, chat/agent paths can pass `None`, and calendar routes retain fallback-owner behavior. Email account helpers treat ownerless rows as single-user/global only for empty-owner mode; for non-empty owners, old ownerless rows are visible only when mailbox/from-address matches. Multi-user callers must continue to pass or derive a non-empty effective owner deliberately.
+
+## Secrets And Local Stores
+
+`ModelEndpoint` includes cached/hidden/pinned model lists, endpoint kind, refresh mode/interval/timeout, model type, supports-tools, owner, optional `provider_auth_id`, provider metadata, and encrypted API key columns. New endpoint columns need matching startup migration helpers.
+
+`ProviderAuthSession` rows hold OAuth/device-flow credential state for providers such as ChatGPT Subscription. Endpoints can reference those rows through `provider_auth_id`; deletion/cleanup must preserve auth rows still referenced by another endpoint and remove orphaned provider-auth rows only after the last endpoint reference is gone.
+
+`McpServer` includes stdio/SSE/HTTP transport config, plaintext env JSON, OAuth config, disabled tool names, and encrypted generic OAuth token/client state in `oauth_tokens`. Generic MCP token storage treats valid non-object JSON as empty state on reads and replaces it with an object on the next write instead of crashing callers.
+
+`CalendarCal.account_id` links synced local calendars back to one saved CalDAV account so multi-account sync/writeback can round-trip remote calendar identity. Remote href/etag columns on calendars and events preserve CalDAV server identity across pull/push cycles, while `caldav_sync_pending` marks local create/update/delete work that still needs remote writeback.
+
+`EncryptedText` owns transparent encrypted-at-rest DB columns via `src.secret_storage` for model endpoint keys and signatures. Email passwords and Google OAuth access/refresh tokens are `String` columns encrypted/decrypted manually. Integrations, CalDAV/CardDAV prefs, and other JSON stores can use `src.secret_storage` directly. API tokens are bcrypt-hashed, API-key manager state uses `data/.key` plus `data/api_keys.json` with restrictive chmod where supported, and vault state in `data/vault.json` is chmod-restricted JSON. Legacy plaintext rows are tolerated until migration or rewrite.
+
+Current JSON/local stores include:
+
+- `data/auth.json` for users, password hashes, TOTP, privileges, and auth settings;
+- `data/sessions.json` for persisted browser session tokens;
+- `data/settings.json`, user preferences, feature flags, integration settings, and `data/embedding_endpoint.json`;
+- presets, API key manager state, memory/skills state, upload metadata, personal docs indexes, research JSON, background jobs, contacts/vault JSON, and task/cookbook auxiliary state.
+
+Cookbook state lives under the shared `DATA_DIR` path through the `COOKBOOK_STATE_FILE` constant. Search cache/analytics, FastEmbed cache fallback, uploads, generated media, logs, and auxiliary SQLite stores also resolve from shared data-dir constants and must work with source, Docker, and frozen data-dir defaults.
+
+`core.atomic_io` owns atomic file-write behavior for auth/settings/integration-style stores. Its JSON and text writers use a random UUID suffix per write, so concurrent writers in the same process cannot collide on a constant PID-derived temporary path, and a `finally` cleanup unlinks any orphaned temp after serialization, fsync, or replace failure while ignoring cleanup errors. Upload metadata uses its own locked atomic writer with `.bak` recovery and can rewrite owner fields plus owner-qualified index keys during user rename. Its cache signature covers the live and backup files by device, inode, size, nanosecond mtime, and ctime; reads recheck the whole signature so same-timestamp corruption or replacement cannot pair stale parsed data with a fresh identity. Destructive reads require a valid live index and never use backup recovery as deletion authority. Attachment-bearing chat/session, document, note, and calendar writers take owner-checked upload reservations before durable writes; reservations share the upload-index lock with cleanup and access-time refresh. Cleanup receives a complete reference snapshot and removes only expired uploads proven unreferenced with coherent index state. Missing/incomplete scans fail closed, and index rows are restored when byte deletion fails.
+
+Memory mutations have their own fail-closed durability contract: `MemoryManager.load_all_for_update()` raises `MemoryStoreUnreadable` for a corrupt or unreadable `memory.json`, and read-modify-write callers use that strict path so they cannot replace an unreadable store with an empty one. Read-only `load_all()` remains lenient and can degrade to no memories; legacy `memory.txt` migration remains supported.
+
+Persisted memories, skills, documents, email, RAG chunks, notes, and other user-editable data are untrusted when reintroduced to model context. Route and processor code must pass them through the untrusted-context contract described in `context-building.md` and `auth-security.md`.
+
+## Backup And Restore
+
+`routes/backup_routes.py` owns narrow admin HTTP JSON export/import for memories, presets, skills, settings, features, and prefs. Skill import writes through the disk-backed skills manager API. This is not a full system restore path.
+
+`scripts/odysseus-backup` owns local `data/` snapshot/restore, with some large/runtime subtrees such as deep research and mail attachments behind flags. It uses SQLite backup APIs, includes secret-bearing key files and stores, validates restore archives against path escapes and link entries, and skips list entries that disappear or become unstatable during directory iteration. Backup artifacts should be treated as sensitive.
+
+## Transitional Notes
+
+The repo still mixes database-backed and JSON-backed persistence. Some domains have both legacy manager state and newer SQLAlchemy rows. `src.database` remains a live compatibility import path. `services/memory/memory.py` and `services/memory/memory_vector.py` now re-export canonical `src` memory classes; preserve compatibility unless the change explicitly migrates a store and includes backfill/tests.
+
+Docker bind-mounts `data/`, `logs/`, cache/local state, and optional Chroma state. The entrypoint repairs ownership for `PUID`/`PGID` before dropping privileges. POSIX secret files attempt restrictive chmod; Windows permission hardening is best-effort/no-op through platform compatibility helpers.
+
+ChromaDB/vector stores are optional durable storage outside `data/app.db`; missing Chroma degrades RAG, memory-vector, and tool-index features without blocking core SQLite/JSON persistence. Vector collections can be lane-suffixed for custom HTTP embeddings versus FastEmbed fallback. See `documents-rag-uploads.md`.
+
+## Current Gaps
+
+- Migration behavior is centralized but long and manual.
+- Ownerless legacy rows make access-control reasoning harder.
+- Some JSON store shapes are only documented by manager code and tests.
+- Startup migrations lack a legacy-schema/idempotence test harness for owner backfills, encrypted-secret rewrites, and repeated runs.
+- JSON-store atomicity is inconsistent across stores, though shared atomic writers, upload metadata recovery, prefs, and strict memory mutations now have focused coverage.
+- Agent filesystem tools currently allow broad `data/` access; secret-bearing files under `data/` need explicit deny coverage.

+# Research
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers deep research behavior in:
+
+- app wiring and timeout policy in `app.py` and `src/app_initializer.py`;
+- canonical browser/API routes in `routes/research/research_routes.py`, with `routes/research_routes.py` as a compatibility shim;
+- chat-triggered research in `routes/chat_routes.py`;
+- diagnostics in `routes/diagnostics_routes.py`;
+- scheduled research in canonical `routes/task/task_routes.py`, its top-level compatibility shim, and `src/task_scheduler.py`;
+- active runtime code in `src/research_handler.py`, `src/deep_research.py`, `src/research_utils.py`, and `src/visual_report.py`;
+- search/fetch dependencies in `src.search`, `services.search`, and the `src.search.content` compatibility alias;
+- compatibility/public service code in `services/research/research_handler.py` and `services/research/service.py`;
+- agent tools in `src/tool_implementations.py`, `src/tool_execution.py`, and `src/tool_index.py`;
+- research CLI access in `scripts/odysseus-research`;
+- frontend modules `static/js/research/panel.js`, `static/js/research/jobs.js`, `static/js/researchSynapse.js`, `static/js/chat.js`, `static/js/chatRenderer.js`, `static/js/chatStream.js`, `static/js/documentLibrary.js`, `static/js/sessions.js`, and compare stream research UI;
+- persisted reports under `data/deep_research/*.json`;
+- tests under `tests/test_research_*`, `tests/test_deep_research_*`, `tests/test_visual_report*.py`, `tests/test_services_research_low_quality_sources.py`, `tests/test_svc_research_sources_nondict.py`, research auth regressions, endpoint fallback tests, and research CLI tests.
+
+## Current Call Sites Include
+
+- panel-launched research through `/api/research/start`;
+- chat-stream research mode, including clarification, continuation from prior research JSON, progress events, and consumed results;
+- non-streaming chat inline research context;
+- compare/chat frontend research indicators;
+- agent `trigger_research` and `manage_research`;
+- scheduled research tasks that write compatible report JSON directly;
+- diagnostics `/api/test-research`;
+- report library, visual report, hide/unhide image, archive/delete, spinoff, and CLI list/show/report/search/delete flows.
+
+## Job Ownership
+
+`src.research_handler.ResearchHandler` owns panel and chat-stream active research jobs: validation, query synthesis, model probing, endpoint/model selection inputs, task registry state, cancellation, progress, raw findings, result persistence, average-duration caching, owner stamping, and owner rename for active/disk-backed task state.
+
+`routes.research.research_routes` owns the browser/API surface: auth and privileges, active/status/cancel/result/result-peek/stream routes, report HTML, hide/unhide images, library/detail/archive/delete, endpoint resolution for panel launch, and spinoff chat creation. Top-level `routes.research_routes` is a `sys.modules` compatibility shim.
+
+Internal-tool owner forwarding rejects only request sentinel identities. The reserved Default/Local storage owner is allowed to own research state in explicit no-login storage flows, while named-user lookups and route gates remain authoritative in configured auth mode.
+
+`TaskScheduler` owns scheduled research execution. It uses `DeepResearcher` directly, creates `[Research]` chat sessions, and writes `data/deep_research/*.json` in a compatible library/report shape without going through `ResearchHandler.start_research()`.
+
+The built-in `tidy_research` action removes only empty or unparseable report JSON. Because those broken files have no readable owner stamp, `src.builtin_actions` refuses the sweep unless the stored task owner is an admin or the app is in explicit auth-disabled single-user mode; refusal happens before file enumeration.
+
+Agent tools and the CLI read and mutate persisted research JSON directly. They are separate policy surfaces and must not be assumed to inherit browser route owner gates.
+
+## Research Runtime
+
+`src.deep_research.DeepResearcher` owns multi-round research work:
+
+- date/context setup;
+- search provider selection and fallback through `src.search.providers` and `src.search.core`;
+- URL/content fetching through `src.search.fetch_webpage_content`;
+- separate tracking of analyzed URLs, last search errors, and empty-round limits;
+- source summarization/extraction;
+- synthesis into final answers/reports;
+- partial/fallback reports when extraction or synthesis fails.
+
+Panel runtime behavior:
+
+- reconnects to active jobs through `/api/research/active`;
+- starts jobs through `/api/research/start`;
+- streams progress over `/api/research/stream/{id}`;
+- falls back to status polling when SSE is unavailable;
+- reads non-destructive results through `/api/research/result-peek/{id}`;
+- opens visual reports from persisted JSON.
+
+Chat-stream runtime behavior:
+
+- first vague research messages can ask clarifying questions and set `research_pending`;
+- later messages synthesize a focused research query;
+- prior persisted research can seed continuation;
+- progress, sources, raw findings, and `research_done` are emitted as SSE events;
+- `/api/research/result/{id}` is destructive for chat consumption and marks/clears consumed in-memory results.
+
+Spinoff/Discuss creates a new chat session from a saved report. It seeds the report text as a system primer with `research_spinoff_from` metadata, uses the source session owner/endpoint context where available, disables RAG by default for the new session, and keeps source details out of the chat context to avoid fabricated citations.
+
+## Reports And Persistence
+
+Research persistence uses `data/deep_research/<session_id>.json`. Current JSON can include result/report text, raw report, sources, raw findings, stats, category, archived state, hidden images, owner, timestamps, and consumed state.
+
+Route access to persisted report files is path-confined. Browser routes validate
+session ids against `^[a-zA-Z0-9-]{1,128}$`, enumerate trusted `*.json` files
+under the resolved research storage root, match by exact filename, reject
+symlink/path escapes after `resolve().relative_to(root)`, and then perform owner
+checks before detail/archive/delete/result-peek/spinoff reads or mutations.
+Invalid ids return 400; missing or cross-owner reports return 404.
+
+`src.visual_report` owns HTML report generation from markdown-like research output, heading/TOC processing, category styling, image injection, allowlist sanitization of untrusted rendered HTML, and client-side controls for hiding images and discussing reports.
+
+Research library thumbnails prefer visible source/report images and Open Graph images, while avoiding obvious logos/icons and blocked/hidden images.
+
+`clear_result()` marks/clears in-memory state; it does not delete the on-disk report. Library/detail/report/archive/delete routes operate on persisted JSON.
+
+## Frontend Panel
+
+`static/js/research/panel.js` owns the research modal/panel UI, settings, provider controls, job cards, result rendering, destructive actions, progress display, and library counts.
+
+`static/js/research/jobs.js` owns active-job adoption, SSE connection, polling fallback, cancel, and result-peek flow. `researchSynapse.js` owns the compact running-state indicator. Chat and library frontend modules own report buttons, discuss/spinoff entry points, and older library views.
+
+## Degraded Runtime
+
+- `/api/research*` is exempt from the app-level hard request timeout.
+- `ResearchHandler.start_research()` applies `research_run_timeout_seconds`; `0` means unlimited and bounded settings protect accidental extremes. User-selected round count is threaded into `DeepResearcher`; `max_rounds=0` means automatic mode capped by the route/handler rather than unbounded research.
+- Deep extraction has separate timeout and concurrency controls.
+- Scheduled research currently uses its own fixed max-time behavior.
+- Probe failures are formatted before long jobs start.
+- Search provider failure records `_last_search_error` and degrades through provider chains or empty results.
+- Fetch/extraction failures skip individual sources when possible.
+- Synthesis/final-report failures should preserve gathered material where possible.
+- Provider, search, fetch, or model offline states should become failed/degraded job state, not app crashes.
+
+Native/Docker endpoint behavior is delegated to model endpoint registration and `src.endpoint_resolver`. Research does not guarantee useful output without a working model plus some usable search/fetch source path.
+
+## Compatibility State
+
+The active FastAPI app path uses `src.research_handler.ResearchHandler`.
+
+`services/research/service.py` is a public wrapper around a duplicate `services.research.research_handler.ResearchHandler`. That services handler remains compatibility/cleanup surface rather than canonical runtime truth; check parity before assuming it has every active-route field or policy behavior.
+
+Its source extraction skips non-dict finding rows so one malformed cached or
+generated entry does not discard later valid URL/title/summary sources.
+
+Search compatibility also matters: `src.search.core`, `src.search.providers`, and `src.search.content` alias the service search path so old imports stay live without a second fetch implementation.
+
+## Security Policy
+
+Research routes require an authenticated user, and start routes require research privilege. Persisted report access and mutations should return 404 for cross-owner or null-owner JSON. Archive/delete/hide-image/unhide-image must preserve owner gates.
+
+Endpoint secret policy:
+
+- `/api/research/start` must use owner-scoped enabled endpoints before decrypted API keys/base URLs are passed to the handler;
+- endpoint/model selectors should resolve `ProviderAuthSession`-backed endpoints for the acting owner and filter non-chat/image-only models out of research model lists;
+- spinoff/follow-up endpoint selection should keep using owner-scoped endpoint context when present;
+- token-authenticated behavior must preserve token owner/scope expectations before being treated as an API surface.
+
+Research sources, fetched pages, summaries, generated reports, and saved research context are untrusted data when reused in chat or another model call. Fetched webpage content in `DeepResearcher` is wrapped with `untrusted_context_message("webpage", content)` before extraction; other reuse paths should keep the same user-role/metadata policy.
+
+Visual reports render model/source-influenced Markdown into HTML with inline JavaScript and remote images. Markdown HTML is allowlist-sanitized; category-derived CSS/classes, links, and image URLs need continued policy coverage. Report HTML remains a security-sensitive rendering surface.
+
+## Testing Coverage
+
+Existing useful coverage includes deep-research runtime/degraded tests, handler/service tests, persisted route owner-scope tests, endpoint selection tests, auth regressions, visual report tests, query fallback tests, and CLI preview/store tests.
+
+Coverage is still thin around live job route ownership, `/api/research/start` route behavior, SSE/result-peek/cancel edges, spinoff endpoint ownership, tool/CLI direct JSON access, remote-image policy, and frontend panel/jobs behavior.
+
+## Current Gaps
+
+- Consolidate, retire, or clearly deprecate `services/research/research_handler.py`.
+- Decide whether direct JSON access by `manage_research` and `scripts/odysseus-research` must be owner-filtered like browser routes or is local/tool-only.
+- Spinoff endpoint fallback needs continued owner-scoped endpoint regression coverage.
+- Spinoff research context is preserved during trimming through metadata, but the system-message primer still needs an explicit policy decision versus the shared untrusted-context role/metadata wrapper.
+- Research search/fetch logic does not yet share a single result shape with chat prefetch and agent tools.
+- Visual report remote image policy needs stronger regressions.
+- Scheduled research persistence needs dedicated route/library/report visibility coverage.
+- Frontend research jobs/panel/SSE fallback behavior lacks direct tests.

+# Runtime
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers current app runtime wiring in:
+
+- `app.py`;
+- `src/app_initializer.py`;
+- `src/runtime_paths.py`;
+- `src/config.py`;
+- `core/constants.py`;
+- `src/constants.py`;
+- `src/interactive_gate.py`;
+- `src/host_docker_access.py`;
+- `core/middleware.py`;
+- all route setup functions registered from `app.py`, including canonical
+  `routes/admin_wipe/`, `routes/cleanup/`, `routes/compare/`, `routes/contacts/`, `routes/document/`, `routes/gallery/`, `routes/history/`, `routes/mcp/`, `routes/memory/`, `routes/note/`, `routes/research/`, `routes/search/`, `routes/task/`, `routes/vault/`, and `routes/webhook/` packages plus top-level compatibility shims;
+- `routes/prefs_routes.py`, `routes/workspace_routes.py`, and `companion/routes.py`;
+- `src/generated_images.py` for generated-media file resolution;
+- `launcher.py`, `Odysseus.spec`, and platform launcher scripts where frozen/native startup changes runtime paths;
+- static entrypoints in `static/index.html`, `static/login.html`, and `static/app.js`.
+
+## App Orchestrator
+
+`app.py` owns process-level startup and HTTP composition. It configures MIME types, `.env` loading, logging under `DATA_DIR/logs`, CORS, gzip compression, auth middleware, request timeout middleware, static files, generated-image serving, router registration, SPA HTML routes, health/readiness/runtime endpoints, and lifespan hooks. Its console, rotating-file, and direct-uvicorn logging levels use the existing `LOG_LEVEL` environment toggle and default to `INFO`; invalid levels also fall back to `INFO`. `core/middleware.py` owns security headers, admin helpers, and internal-tool token constants.
+
+`src/app_initializer.initialize_managers()` owns shared manager construction. It creates memory, skills, sessions, uploads, personal docs, API keys, presets, chat processor/handler, research handler, model discovery, and optional memory vector store. Route modules receive these dependencies from `app.py`; they should not recreate manager singletons.
+
+`app.py` separately owns runtime singletons and integration hooks for auth, vector RAG, TTS/STT, webhooks, scheduled tasks, MCP, assistant log globals, event bus wiring, AI interaction globals, API-token cache invalidation, and foreground activity tracking. `src.runtime_paths` owns source-versus-frozen app/data path resolution; `src.constants` derives `DATA_DIR` from `ODYSSEUS_DATA_DIR` or that runtime default. `core/constants.py` and `src/constants.py` are both live import paths and are not fully identical today, so new constants need explicit placement/compatibility decisions.
+
+The shared upload handler is also installed on the session manager and tool
+helper, and `app.py` injects it into attachment-bearing route factories so
+durable writers and cleanup use one lifecycle owner.
+
+## Routes And Static Serving
+
+Current router call sites include:
+
+- auth, uploads, emoji, sessions, admin wipe, memory, skills, chat, workspace, research, history, search, presets, diagnostics, cleanup, personal docs, embeddings, model endpoints;
+- TTS/STT, documents, signatures, gallery, editor drafts, scheduled tasks, assistant, calendar, shell, Cookbook, HW Fit, compare, preferences, backup, fonts, Copilot and ChatGPT Subscription auth;
+- MCP, webhooks, API tokens, notes, email, Codex/Claude scoped APIs, vault, contacts, and companion routes.
+
+Admin wipe, cleanup, compare, contacts, documents, gallery, history, MCP, memory, notes, research, search, tasks, vault, and webhooks have canonical subpackage modules. Their old top-level route modules replace their `sys.modules` entries with the canonical module object so legacy imports, `importlib`, and monkeypatch tests target the same module that `app.py` uses. `app.py` imports task setup from `routes.task.task_routes`.
+
+The SPA routes `/`, `/notes`, `/calendar`, `/cookbook`, `/email`, `/memory`, `/gallery`, `/tasks`, and `/library` all serve `static/index.html`. `static/` is served with revalidation for `.js`, `.css`, and `.html` because the frontend ships raw browser modules with no hashed build output.
+
+Direct app-owned endpoints include `/api/generated-image/{filename}`, `/backgrounds`, `/login`, `/api/version`, `/api/health`, `/api/ready`, `/api/runtime`, and `/api/activity/heartbeat`. `/backgrounds` points at `static/backgrounds.html`; if that file is absent or the route remains auth-gated, that is route/static drift rather than an intentional public contract.
+
+`/static/*` is auth-exempt and public. SPA HTML routes are auth-gated except `/login`, and they are nonce-injected dynamic `HTMLResponse` values outside the static mount. Generated images and videos are served from `data/generated_images` through the generated-image resolver with immutable/nosniff caching.
+
+## Runtime Security Boundaries
+
+Effective middleware order matters. CORS, `SecurityHeadersMiddleware`, `_RequestTimeoutMiddleware`, and GZip middleware are added before `AuthMiddleware`; auth short-circuit responses can therefore bypass downstream app handlers and should be tested when changing response headers or auth behavior. Text responses can be compressed when they pass through the app stack.
+
+Security headers include HSTS and a restrictive `Permissions-Policy` that disables camera/geolocation and only allows microphone from self.
+
+`_TIMEOUT_EXEMPT_PREFIXES` owns hard-timeout bypass policy. It is prefix-based and currently exempts all subroutes under `/api/chat`, `/api/shell/stream`, `/api/research`, `/api/model/download`, `/api/model/probe`, `/api/model-endpoints`, `/api/cookbook/setup`, `/api/upload`, `/api/image`, and `/api/memory/audit`. Memory audit has its own longer inactivity timeout.
+
+Generated-image path resolution fails closed for invalid names, path escape, and missing files. Ownership checks are best-effort when a current user exists: gallery rows owned by a different user return 404, rowless generated files are allowed, and DB/helper failures fail open. See `auth-security.md` for `LOCALHOST_BYPASS`, internal-tool loopback, proxy-header exclusion, and owner-impersonation policy.
+
+## Runtime Behavior
+
+- Request hard timeout applies to non-exempt paths that reach `_RequestTimeoutMiddleware`.
+- `src.interactive_gate` tracks foreground requests, browser heartbeats, and active chat streams. Background task/email work can wait for a quiet window so scheduled jobs do not compete with visible browser or model activity. Status polling and `/api/email/unread-state` are passive reads: they do not cancel running scheduled work or manufacture foreground pressure.
+- YouTube support is initialized through `services.youtube.init_youtube()`.
+- Vector document RAG is initialized lazily through `src.rag_singleton.get_rag_manager()` and may be unavailable at startup.
+- `routes.workspace_routes` lets the browser choose a server directory for agent turns; execution confinement is enforced below the route layer by tool execution.
+
+## Lifespan Startup
+
+Upload cleanup first snapshots durable chat, document, gallery, note, and
+calendar references and aborts on scan or upload-index integrity failure.
+
+Startup purges leftover incognito sessions, reconciles default scheduled tasks before the task runner starts, and backfills legacy skill owners when possible.
+
+Startup fire-and-forget work includes upload cleanup, background-job monitoring, MCP built-in registration and user-server connection, tool-index warmup, model-endpoint warmup, endpoint keepalive, Cookbook serve lifecycle monitoring, hourly null-owner sweeps, and nightly skill audit. The in-process task scheduler is gated by `ODYSSEUS_INPROCESS_TASKS`; email polling is started from email route setup and gated separately by `ODYSSEUS_INPROCESS_POLLERS`. Foreground-gate knobs are `BACKGROUND_TASK_FOREGROUND_GATE`, `BACKGROUND_TASK_QUIET_MS`, `BACKGROUND_TASK_MAX_WAIT_SECONDS`, and `BACKGROUND_TASK_BROWSER_ACTIVE_SECONDS`.
+
+Shutdown cancels upload cleanup, stops the task scheduler, closes the webhook manager, and disconnects MCP servers.
+
+## Degraded And Platform Behavior
+
+- On Windows, HuggingFace symlink warnings are disabled so model files copy instead of symlink on network/UNC paths.
+- `.env` is loaded with `utf-8-sig` to tolerate Notepad BOM files.
+- Auth and middleware path checks use Starlette's application-relative route path, so a deployment mounted under `root_path` keeps segment-aware auth exemptions, timeout policy, and login redirects instead of comparing proxy prefixes as application routes.
+- Process-wide MIME registration forces stable `.js` and `.mjs` types across native platforms.
+- Frozen/PyInstaller builds use `src.runtime_paths` so bundled app assets resolve from the executable payload while persistent data defaults to `~/.odysseus/data`; normal source runs still default to the repository `data/` directory unless `ODYSSEUS_DATA_DIR` overrides it.
+- Docker detection in `/api/runtime` selects `host.docker.internal` as the Ollama default inside containers and `127.0.0.1` natively. Compose sets Chroma to `chromadb:8000`; native Chroma defaults live in `src/chroma_client.py`.
+- `src.host_docker_access` treats host Docker access from inside the container as opt-in. Default Compose does not mount `/var/run/docker.sock`; `docker/host-docker.yml` plus `ODYSSEUS_ENABLE_HOST_DOCKER=true` are required before local container code considers the host Docker daemon available.
+- Chroma-backed consumers degrade independently: personal-doc RAG can return route-level 503s, semantic memory vectors can be dropped from chat/memory wiring, and the tool index can fall back when vector retrieval is unavailable.
+- RAG startup failure is throttled so failed clients do not poison later retries.
+- MCP startup is asynchronous and non-critical. User-server connection is bounded, failures surface through MCP status routes, and builtin MCP calls can reconnect after crashes.
+- `/api/health` is liveness only. `/api/ready` checks database reachability, writable data dir, and local-first storage metadata; it does not prove optional subsystem health for RAG, Chroma, MCP, memory vectors, tool index, or endpoint warmups.
+- `/api/diagnostics/services` is an admin diagnostics endpoint for optional service health. It reports bounded, non-intrusive checks for ChromaDB, SearXNG, email accounts, ntfy, and model provider endpoints with `ok`/`degraded`/`down`/`disabled` style status values and strips secret-bearing URLs/errors. `/api/diagnostics/logs` returns a bounded tail of the app log for admin troubleshooting.
+
+## Current Gaps
+
+- `app.py` is still a large route registry and runtime orchestrator. There is no generated route manifest or smaller runtime composition layer yet.
+- Long-running route timeout exemptions are manual and prefix-based; new SSE/proxy/task paths can be missed, while broad prefixes can exempt more routes than intended.
+- Runtime tests cover small helper slices, but not full app import/TestClient behavior for mounted static cache headers, generated-image serving, timeout middleware, middleware order, lifespan startup wiring, or route/static drift.
+- The diagnostics service-health endpoint is not a readiness gate and does not cover every optional subsystem.

+# Search
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers web search, URL fetching, and search-derived context in:
+
+- canonical `routes/search/search_routes.py`, with `routes/search_routes.py` as a compatibility shim;
+- reusable outbound transport primitives in `src/outbound_fetch.py`;
+- `services/search/*` and exported `services.search.SearchService`;
+- `src/search/*` compatibility aliases around canonical service modules;
+- search call sites in `src/chat_processor.py`, `src/tool_execution.py`, `src/session_search.py`, `src/research_handler.py`, `src/deep_research.py`, and `services/research/research_handler.py`;
+- search settings in `src/settings.py`, `static/js/settings.js`, and compare/research frontend search callers;
+- YouTube context paths in `src/youtube_handler.py` and `services/youtube/youtube_handler.py`;
+- research visual/report consumers in `src/visual_report.py` and `routes/research/research_routes.py`;
+- tests under `tests/test_search_*`, `tests/test_service_search_*`, `tests/test_services_search_*`, `tests/test_security_regressions.py`, `tests/test_agent_loop.py`, `tests/test_deep_research_*`, `tests/test_research_handler_*`, `tests/test_youtube_*`, and `tests/test_og_image_extraction.py`.
+
+`routes/chat_routes.py` also exposes `GET /api/search`, but that route searches chat messages and belongs to chat history behavior, not web search.
+
+## Route Flows
+
+`routes/search/search_routes.py` owns the browser/API web-search routes:
+
+- `GET /api/search/config` returns search configuration with provider key presence, not secret values;
+- `POST /api/search` calls `comprehensive_web_search(..., return_sources=True)` and returns `{context, sources, error?}`;
+- `GET /api/search/providers` returns provider metadata and availability;
+- `POST /api/search/query` calls one provider directly and returns `{results, provider, time, error?}` without ranking, fallback chains, cache formatting, or content fetch.
+
+Compare mode uses both route shapes: shared presearch uses `/api/search`, while provider/search comparison panes use `/api/search/query`. Research panels can pass provider override settings through research routes into the deep-research search path.
+
+Research provider naming is not fully normalized in the UI: some frontend selectors still use `google`, while provider dispatch expects `google_pse`.
+
+## Search Pipeline
+
+`services/search/core.py` owns `comprehensive_web_search()`. It coordinates provider selection, fallback chains, ranking, optional fetch/content extraction, formatted prompt context, cache invalidation, and analytics.
+
+`services/search/service.py` owns `SearchService`, the async facade exported by `services.search` and `services`. It wraps the synchronous comprehensive search path off the event loop and maps route-style output into service result rows.
+
+`services/search/providers.py` owns provider-specific calls for SearXNG, Brave, DuckDuckGo, Google PSE, Tavily, and Serper. `PROVIDER_INFO`, provider availability, missing-key behavior, and provider dispatch live there.
+
+`services/search/query.py` owns query enhancement and sanitization, including stripping markdown/code-fence noise from model- or user-supplied queries before provider calls and extracting Unicode/non-ASCII capitalized entity names. `services/search/ranking.py` owns result ranking, including word-boundary title/snippet/subject matching so short query terms do not match unrelated substrings.
+
+## Provider Settings And Fallback
+
+`src/settings.py` owns default provider settings. The default provider is SearXNG, with DuckDuckGo as the default fallback chain. `static/js/settings.js` owns the admin search settings UI, provider key presence display, provider selection, and fallback ordering. SafeSearch is a backend/provider setting today, not a visible Settings control.
+
+Provider API keys come from settings or environment at call time. Web config routes expose availability/presence only, non-admin settings reads are scrubbed, and chat settings tools cannot set provider credentials.
+
+Runtime behavior:
+
+- disabled search returns disabled/unavailable text in the comprehensive path;
+- missing keyed-provider secrets return empty provider results instead of exposing secrets;
+- SearXNG retries through JSON variants before HTML fallback, pins English/general-engine defaults where needed, and maps news/recency settings into provider time filters;
+- comprehensive search retries providers and then walks the fallback chain;
+- `/api/search/query` is a direct provider test/query path and does not use the comprehensive fallback chain. Direct provider result limits can be controlled dynamically by the caller.
+
+## Content Fetching
+
+`src.outbound_fetch.py` owns reusable synchronous public-URL classification, one-resolution-per-hop DNS pinning, redirect handling, and response-body budgets without search/content-extraction dependencies. `services/search/content.py` adapts those primitives and owns webpage extraction/cache/result shaping for the services path:
+
+- public HTTP/HTTPS URL checks;
+- DNS fail-closed behavior;
+- rejection of localhost, metadata, private, reserved, multicast, and link-local targets;
+- redirect revalidation on each hop;
+- one-time public DNS resolution per hop plus an `httpcore`/`httpx` pinned
+  transport that connects to the validated public IP while preserving the
+  original URL, Host header, and TLS SNI, closing DNS-rebinding time-of-check
+  drift;
+- metadata, Open Graph image, list, table, code block, PDF, and text extraction;
+- readable text extraction for `text/*`, Markdown, `.txt`, `.json`, `.jsonl`, and JSON content types;
+- central User-Agent behavior through `WEB_FETCH_USER_AGENT`;
+- soft and hard download byte caps through `WEB_FETCH_SOFT_MAX_BYTES` and `WEB_FETCH_HARD_MAX_BYTES`, with declared-length and streaming-budget checks; requests prefer identity transfer encoding so compressed bodies cannot bypass the effective body cap;
+- JS-heavy empty result hints;
+- cache writes;
+- empty/error result shape, including explicit HTTP-status failures instead of raising through callers.
+
+`src/search/content.py` is now a compatibility alias to `services.search.content`; chat URL auto-fetch, agent `web_fetch`, and deep research keep the `src.search` import path but share the services implementation.
+
+Agent `web_fetch` raises the per-call budget only within the global hard cap, leads tool output with a partial-content notice when the download budget truncated the page, and then applies normal tool-output truncation so the notice survives.
+
+Content failures are caller-shaped:
+
+- comprehensive search drops failed page fetches and keeps usable search context;
+- `web_fetch` returns tool errors, including bot-protection and HTTP-status failures;
+- direct URL chat prefetch turns failures into compact untrusted unavailable-page context without exposing raw URL/exception/response diagnostics;
+- deep research records search/provider failures separately from extraction failures.
+
+## Result Shapes
+
+Search does not have one canonical result shape yet. Current shapes include:
+
+- `/api/search`: `{context, sources, error?}`;
+- `/api/search/query`: `{results, provider, time, error?}`;
+- `comprehensive_web_search(return_sources=True)`: formatted context plus `{url, title}` sources;
+- `SearchService.search()`: service result rows;
+- agent `web_search`: tool output text plus a hidden sources marker stripped by the agent loop;
+- agent `web_fetch`: fetched page text or tool error;
+- deep research: findings, cited sources, optional source images, and `_last_search_error` state.
+
+Chat/session transcript search is separate from web search but now uses `chat_messages_fts` when available, sanitizes FTS queries, and batches message lookup after FTS hits to avoid per-hit database reads.
+
+Search owns Open Graph image extraction for fetched pages. Research owns promotion of those images into research sources and visual reports. This is not a standalone web image-search provider or gallery image proxy.
+
+## YouTube
+
+`services/youtube/youtube_handler.py` owns YouTube URL detection, id extraction, transcript, comment, and formatting behavior. `src/youtube_handler.py` is a compatibility alias to the canonical services module so startup `init_youtube()` state and chat imports share one implementation.
+
+YouTube transcript and comment content is search-like external context. URL parsing covers common watch, mobile/music, embed, `/v/`, shorts, live, and `youtu.be` forms and must tolerate non-string input.
+
+## Compatibility State
+
+`src/search/core.py`, `src/search/providers.py`, `src/search/ranking.py`, `src/search/cache.py`, `src/search/content.py`, `src/search/query.py`, and `src/search/analytics.py` are compatibility shims or module aliases around `services.search`. Ranking helpers exposed through `src.search.ranking` include recency scoring, result ranking, naive-UTC handling, `_SPORTS_HINT_RE`, and age formats.
+
+`src.youtube_handler` remains a compatibility import path, but it should resolve to the same module object as `services.youtube.youtube_handler`.
+
+## Context Policy
+
+Search results, fetched pages, Open Graph metadata, and YouTube transcript/comment content are untrusted context.
+
+Chat search, chat URL prefetch, compare presearch, and YouTube context wrap inserted content through the shared untrusted-context message helpers. Agent `web_search`/`web_fetch` results are read-only tool outputs and must not be treated as instructions.
+
+Deep research wraps fetched webpage content through `untrusted_context_message("webpage", content)` before extractor calls, though search result/failure shapes still differ from chat and agent tools.
+
+## Optional And Platform Behavior
+
+`ddgs` is optional; provider code has an HTML fallback. Search cache and analytics state live under the shared data dir and mkdir failures in read-only image layers are tolerated where possible. PDF extraction uses `pdfminer.six` only when installed. Native SearXNG defaults to `http://localhost:8080`; Docker uses the compose `searxng` service URL and pins the SearXNG image with a healthcheck.
+
+Compose preserves retained SearXNG settings but runs `scripts/migrate_searxng_settings.py` before startup to add missing `use_default_settings: true` inheritance. The migration accepts only a regular single-document YAML mapping, preserves BOM/newline/style/ownership/mode, writes and directory-fsyncs atomically, and no-ops when the key exists. Compose treats migration failure as non-fatal so SearXNG health reports the retained-file problem instead of the wrapper command preventing startup.
+
+`httpx` and BeautifulSoup are required runtime dependencies for the active search/fetch path.
+
+## Current Gaps
+
+- Search route handlers need direct tests for request body formats, provider validation, provider availability, and route error/empty-result shapes.
+- Agent search, chat search prefetch, and research search do not yet share a single result/failure shape.
+- `src/search` and `services/search` are mostly consolidated through shims, but import-path parity tests remain important.
+- Deep-research webpage-content extraction uses the shared untrusted wrapper, but synthesis/reuse boundaries still need route/tool tests.
+- Search-sourced `og_image` URLs need an explicit privacy/security decision: documented direct browser loads, public-URL validation, or a same-origin proxy.
+- Route and integration tests do not fully pin chat/compare/YouTube untrusted-context insertion.

+# Settings And Admin Surfaces
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers settings and admin surfaces in:
+
+- `app.py` auth-exempt and route-registration wiring;
+- `routes/auth_routes.py` for setup, login/status, users, features, settings, and integration settings routes;
+- `core/auth.py` and `core/middleware.py` admin/privilege behavior;
+- `src/settings.py` and `src/settings_scrub.py`;
+- `routes/prefs_routes.py`;
+- `src/preset_manager.py` and `routes/preset_routes.py`;
+- `routes/backup_routes.py` and `scripts/odysseus-backup`;
+- `routes/diagnostics_routes.py`;
+- canonical `routes/admin_wipe/admin_wipe_routes.py`, `routes/cleanup/cleanup_routes.py`, and `routes/vault/vault_routes.py` plus their top-level compatibility shims;
+- `src/cleanup_service.py` and vault-related tool implementations;
+- `routes/font_routes.py`;
+- `routes/model_routes.py` for `/api/tools` and settings-bound model endpoint references;
+- `src/agent_tools/admin_tools.py`, `src/tool_implementations.py`, `src/tool_execution.py`, `src/tool_schemas.py`, and `src/tool_index.py` for `manage_settings`;
+- `src/agent_loop.py` for stale agent prompt references to settings APIs;
+- frontend modules `static/js/appConfig.js`, `static/js/settings.js`, `static/js/settings/{registry,navigation,lifecycle,search,dom,sidebar}.js`, `static/js/admin.js`, `static/js/presets.js`, `static/js/theme.js`, and `static/js/storage.js`;
+- CLI helpers `scripts/odysseus-preset` and `scripts/odysseus-theme`.
+
+Generic API integrations are cross-referenced in `integrations.md`. Model endpoint CRUD and endpoint cleanup are covered in `llm-models.md`. Email/contact/calendar legacy setting fallbacks stay with their domain specs.
+
+## Data Stores
+
+`src.settings` owns `data/settings.json` and `data/features.json`. Settings and features are merged over defaults and cached briefly. Missing, corrupt, unreadable, or non-object stores fall back to defaults.
+
+`default_model_fallbacks` is a retired setting key. `src.settings.without_retired_settings()` removes it from loaded/API-visible settings, writes ignore it, and no migration treats it as consent for the owner-scoped `foreground_fallback_enabled` plus ordered `foreground_model_fallbacks` contract.
+
+`routes.prefs_routes` owns `data/user_prefs.json`. It supports:
+
+- `_users` multi-user storage;
+- legacy flat prefs;
+- auth-disabled first-user compatibility without clobbering the rest of `_users`.
+
+`src.settings.get_user_setting()` overlays only a whitelist of per-user prefs over global settings. That whitelist is mostly model/media endpoint choices.
+
+Other active stores include:
+
+- `data/presets.json`;
+- `data/vault.json`;
+- `static/fonts/custom`;
+- DB-backed domain tables used by admin wipe and cleanup;
+- browser localStorage/sessionStorage for theme, preset, privacy, and transient UI state.
+
+## Bootstrap, Auth, And Settings Routes
+
+`routes.auth_routes` owns first-run setup, login/logout/status, password/TOTP flows, signup controls, user CRUD, admin promote/demote, privilege edits, feature flags, and app settings. `app.py` exposes setup/status/features/settings routes before cookie auth so first-run and frontend bootstrap can work.
+
+Settings runtime:
+
+- `GET /api/auth/features` is public feature visibility metadata;
+- `POST /api/auth/features` is admin-only;
+- `GET /api/auth/settings` returns full settings to admins;
+- non-admin or unauthenticated `GET /api/auth/settings` returns `scrub_settings()` output;
+- `POST /api/auth/settings` is admin-only and only writes keys present in `DEFAULT_SETTINGS`.
+
+`src.settings_scrub` owns deep secret-key scrubbing for non-admin settings reads, including snake_case and camelCase secret-like key names. It preserves structure while blanking secret-shaped string values.
+
+Admin gates inherit the auth contracts in `auth-security.md`: normal deployments require an admin user, while `AUTH_ENABLED=false`, first-run/setup mode, validated internal-tool loopback, and direct localhost bypass have explicit behavior in auth middleware/helpers.
+
+## Preferences And Frontend State
+
+`routes.prefs_routes` owns per-user key/value preferences. Theme and custom-theme code uses localStorage first, syncs selected prefs through `/api/prefs/*`, and falls back from server prefs when local theme state is absent.
+
+`static/js/theme.js` owns:
+
+- theme and custom-theme persistence;
+- old theme-name migrations;
+- custom font selection and `/api/fonts/custom` discovery;
+- bundled accessibility font selection such as OpenDyslexic and text-size variable application;
+- CSS variable application.
+
+`static/js/settings.js` owns domain panel load/save behavior and compatibility exports, while `static/js/settings/registry.js` is the canonical group/panel metadata inventory. `navigation.js` activates panels and lazy admin content, `search.js` implements the registry-backed finder while filtering admin-only entries, `lifecycle.js` owns modal open/close/Escape/drag/docking behavior, `sidebar.js` owns persisted collapse/resize state, and `dom.js` holds shared DOM helpers. Registry/DOM consistency is a tested contract; new panels must update both the registry metadata and actual DOM. `static/js/appConfig.js` shares one promise cache for settings and tool reads across frontend modules, consumes a login-page settings prefetch once, drops rejected promises for retry, and requires settings/tool writers to invalidate the matching cache; `/api/tools` writes invalidate both entries because disabled tools live in settings state.
+
+Settings panels cover provider/model/search/research/reminder/email/CalDAV/CardDAV/vault, accessibility/font/text-size, scoped tokens, and unified integrations. The hidden legacy fallback editor was removed; no current Settings panel exposes the new foreground fallback keys, so opt-in exists only through owner-scoped preferences/internal callers until a deliberate UI is added. Email OAuth connect preserves the selected SMTP security mode and returns to the Settings surface after callback. `static/js/admin.js` owns user/admin panels, model endpoints, builtin tool toggles, MCP forms, feature toggles, token/webhook panels, diagnostics, backup/import, and danger-zone wipes.
+
+Logout/user-switch flows clear local/session storage to avoid stale cross-account UI state.
+
+## Presets
+
+`src.preset_manager.PresetManager` owns preset persistence, atomic writes, default preset healing, corrupt-store fallback, and legacy custom-preset migration. `routes.preset_routes` owns HTTP behavior.
+
+Runtime behavior:
+
+- preset list/templates/groups/expand routes are read or utility surfaces;
+- custom preset/template/group mutations are admin-gated;
+- preset expansion can call the configured model;
+- frontend activation combines persisted `custom.enabled` with local selected-preset UI state;
+- presets, user templates, and group presets are currently shared stores, not owner-scoped stores.
+
+`scripts/odysseus-preset` is a local CLI for preset store maintenance and backup of `presets.json`.
+
+## Tools Settings
+
+`routes.model_routes` owns `/api/tools`, which writes `settings.json:disabled_tools` for global builtin tool toggles.
+
+`src.agent_tools.admin_tools.do_manage_settings()` owns the model-facing settings tool and is re-exported through `src.tool_implementations`. It is admin-only through tool execution/security policy, writes real global settings, refuses secret-shaped setting writes, refuses structured clobbers, resolves model aliases to endpoints, and can enable/disable tools.
+
+The stale `app_api` prompt text that mentions `/api/settings` is not the canonical settings surface; the live HTTP route is `/api/auth/settings`, and `manage_settings` is the intended agent settings tool. The `manage_settings` schema also still describes free-form preferences even though implementation only accepts keys in `DEFAULT_SETTINGS`.
+
+## Backup And Import
+
+`routes.backup_routes` owns admin JSON export/import for selected app state:
+
+- owner-filtered memories;
+- shared presets;
+- owner-filtered skills;
+- raw global settings;
+- feature flags;
+- per-user preferences.
+
+HTTP export is secret-bearing because it includes raw settings. Treat exported files as sensitive admin artifacts.
+
+HTTP import is best-effort and section-based. It rejects invalid top-level JSON, ignores unrecognized or wrongly typed sections, merges recognized sections, and may partially write earlier sections before a later failure. Memory dedup is scoped to the importing user; imported memories/skills without owners are stamped to the caller, while explicit owner fields are preserved. Skill import writes through the disk-backed `SkillsManager.add_skill()` API, not the removed JSON-era `save()` shape.
+
+`scripts/odysseus-backup` is a separate local `data/` snapshot/restore tool, with some large/runtime subtrees behind flags. It uses SQLite backup where applicable, rejects archives written inside `data/`, validates restore members, refuses links/special files, and skips entries that disappear or become unstatable while a backup directory listing is assembled.
+
+## Diagnostics, Cleanup, And Wipe
+
+`routes.diagnostics_routes` owns admin diagnostics for DB, RAG, YouTube, research status, aggregate optional service health, and application log tails. The service-health endpoint checks ChromaDB, SearXNG, email accounts, ntfy, and model provider endpoints with bounded probes and redacted output. URL-bearing diagnostics should use log-safety redaction helpers so credentials/query strings do not leak. `/api/diagnostics/logs` reads a bounded tail from `DATA_DIR/logs/app.log`, with missing logs returning an empty result. Diagnostics are operational and must avoid growing into broad secret/environment dumps.
+
+`routes.cleanup_routes` is owner-scoped, not admin-only. It previews and applies session cleanup for the current user through `src.cleanup_service`; when auth is disabled, cleanup can operate as a single-user unscoped flow.
+
+`routes.admin_wipe_routes` owns global per-domain destructive wipe actions. Current kinds include chats, memory, skills, notes, tasks, documents, gallery, and calendar. Server enforcement is admin gate plus kind allowlist. Frontend double confirmation in `static/js/admin.js` is user-interface protection, not server authorization.
+
+## Vault
+
+`routes.vault_routes` owns Vaultwarden/Bitwarden CLI config, login, unlock, lock, logout, and `bw_installed` checks.
+
+Runtime behavior:
+
+- `GET /api/vault/config` returns no `session` value;
+- `data/vault.json` stores config and `BW_SESSION`;
+- POSIX saves attempt `0600` permissions;
+- master passwords are passed to `bw` on stdin, not argv;
+- missing `bw` degrades to route error/status responses;
+- corrupt or non-object vault config loads as empty config;
+- lock/logout clear the saved session.
+
+Vault tool paths duplicate some route behavior and can return vault item secrets to an admin tool result after a reason check and audit log. They are admin/local trust-boundary surfaces.
+
+## Fonts
+
+`routes.font_routes` lists user-supplied font files under `static/fonts/custom`. It is a support/discovery route, not an admin operation. `static/js/theme.js` owns consuming this list for theme font selection.
+
+## Security And Provenance
+
+- Non-admin and unauthenticated settings reads are scrubbed.
+- Admin settings reads, admin edit forms, vault flows, backup files, and local CLI artifacts can contain secrets and must remain admin-only or locally protected.
+- Backup artifacts are sensitive because settings may include API keys, passwords, tokens, and endpoint credentials.
+- Diagnostics and logs should avoid adding secret-bearing values.
+- Admin wipe is global per kind and crosses owners.
+- Cleanup is owner-scoped in normal auth mode.
+- `manage_settings` blocks secret-shaped setting writes and structured setting clobbers.
+- Vault master passwords must not appear in process argv.
+- Client-side confirmations are not server authorization controls.
+
+## Degraded And Compatibility Behavior
+
+- Settings/features fall back to defaults on missing/corrupt/unreadable/non-object stores.
+- `is_setting_overridden()` has a narrower error contract than `load_settings()`.
+- Prefs support legacy flat files and auth-disabled first-user writes.
+- Presets heal missing built-ins and legacy custom state without clobbering user edits.
+- `/api/import` is non-atomic section merge.
+- Vault route and vault tool degraded behavior are not identical.
+- Theme/preset frontend helpers tolerate malformed localStorage values.
+- CLI helpers are local maintenance surfaces and may bypass HTTP route policy.
+
+## Testing Notes
+
+Current targeted coverage includes settings store fallback/error paths, settings scrub, shared frontend config caching/invalidation/prefetch behavior, prefs no-clobber behavior, atomic preset store/migration/CLI/localStorage helpers, backup import cross-user dedup, backup CLI restore/list-race safety, cleanup owner scope, diagnostics admin-gate/source/service-health/log-tail checks, admin promote/demote, admin wipe gallery, font family derivation, theme helper behavior, vault password-not-in-argv checks, setup/auth regressions, reserved usernames, Google email OAuth route/helper behavior, and a token-budget `manage_settings` path.
+
+## Current Gaps
+
+- Add route tests for `/api/auth/settings`: anonymous/non-admin scrubbed reads, admin full reads, non-admin POST rejection, and unknown-key ignore behavior.
+- Add route tests for `/api/auth/features` admin writes.
+- Add `/api/tools` and `manage_settings` tests for secret write refusal, enum/integer coercion failures, structured-setting refusal, reset/default behavior, endpoint/model resolution, and tool enable/disable aliases.
+- Add backup tests for secret-bearing export policy, owner-scoped exported sections, invalid import handling, skills dedup, settings/features merge, and admin gates.
+- Add diagnostics tests for broader error redaction and sensitive output limits.
+- Add admin wipe tests for every wipe kind, unknown-kind 400, rollback behavior, and admin gating.
+- Add vault route tests for session omission, permission setting, login/unlock failures, lock/logout clearing, corrupt config, and admin gates.
+- Add broader frontend behavior coverage for Settings/Admin panel save/load flows, vault password clearing, diagnostics buttons, cleanup/wipe confirmations, custom font/theme wiring, and tab state; registry/navigation/finder/lifecycle contracts now have focused source/JS tests.
+- Decide whether `user_templates` and `group_presets` should remain shared despite user-facing names.
+- Decide whether backup/import should preserve explicit owner fields or force imported owner ownership.
+- Continue moving shell/navigation concerns out of the still-large `static/js/settings.js` and `static/js/admin.js` domain boundary without duplicating registry ownership.

+# Shell And MCP
+
+Last updated: dev@2e2bb52 | 2026-08-16
+
+## Scope
+
+This spec covers shell and MCP behavior in:
+
+- shell routes in `routes/shell_routes.py`;
+- the standalone shell helper in `services/shell/service.py`;
+- agent shell/background execution in `src/tool_execution.py`, `src/agent_tools/subprocess_tools.py`, `src/bg_jobs.py`, and `src/bg_monitor.py`;
+- app wiring and startup/shutdown in `app.py`;
+- MCP configuration routes in canonical `routes/mcp/mcp_routes.py`, with `routes/mcp_routes.py` as a compatibility shim;
+- MCP runtime state in `src/mcp_manager.py`;
+- generic MCP OAuth helpers in `src/mcp_oauth.py`;
+- built-in server registration in `src/builtin_mcp.py`;
+- persisted `McpServer` config in `core/database.py`;
+- MCP tool exposure in `src/agent_loop.py`, `src/tool_index.py`, `src/tool_schemas.py`, `src/tool_parsing.py`, `src/tool_implementations.py`, and `src/tool_security.py`;
+- admin MCP/tool helpers in `src/agent_tools/admin_tools.py`;
+- built-in servers in `mcp_servers/*.py`;
+- Settings/Admin UI in `static/js/settings.js` and `static/js/admin.js`;
+- CLI helper `scripts/odysseus-mcp`;
+- Docker/native dependency context in `Dockerfile` and `docker-compose.yml`.
+
+Cookbook model-serving shell flows are covered in `cookbook-hwfit.md`; this spec owns the shared shell and MCP surfaces they reuse.
+
+## Shell Routes
+
+`routes.shell_routes` owns `/api/shell/exec` and `/api/shell/stream`. These routes are powerful by design and are admin-only. They execute admin-provided command strings through the host shell.
+
+Runtime behavior:
+
+- `/api/shell/exec` runs a bounded command and returns stdout, stderr, and exit code;
+- `/api/shell/stream` streams SSE output through plain pipes, POSIX PTY, POSIX tmux log tailing, or a Windows detached-log fallback depending on request flags and platform;
+- empty commands return an error result without spawning a shell;
+- timeouts kill the subprocess where possible;
+- disconnects can stop streaming subprocesses;
+- POSIX PTY support is optional and reports an unsupported event when unavailable.
+
+`routes.shell_routes` also owns shell-adjacent Cookbook dependency endpoints:
+
+- `/api/cookbook/packages`;
+- `/api/cookbook/packages/install`;
+- `/api/cookbook/rebuild-engine`.
+
+Those endpoints probe local or SSH-remote packages, prepend user install bins for pip CLIs, validate SSH host/port through shared route validators, validate remote venv values, and restrict package installs to allowlisted dependencies.
+
+`services.shell.service.ShellService` is a small standalone subprocess abstraction with output caps. It does not own live route behavior, PTY/tmux paths, Windows shell selection, admin checks, or Cookbook package probes.
+
+## Agent Shell And Background Jobs
+
+`src.tool_execution` owns agent-side `bash` execution and the `#!bg` marker. A `bash` block whose first line is `#!bg` starts a detached background job instead of holding the chat stream open. On Windows, request-scoped workspace shell execution prefers Git Bash when available so POSIX-style agent commands and path confinement use the intended shell instead of `cmd.exe` parsing.
+
+`src.bg_jobs` owns disk-backed job state under `data/bg_jobs.json` and `data/bg_jobs/*`. It stores wrapper scripts, logs, exit-code files, timestamps, status, and capped result text.
+
+`src.bg_monitor` owns polling and auto-continuation. When a job finishes, it injects the job result into the session, drains the agent stream, persists only the assistant continuation plus `bg_result` metadata, and marks the job followed up.
+
+Runtime behavior:
+
+- background jobs are restart-tolerant while their state files remain;
+- jobs have a maximum runtime and stale cleanup window;
+- output is capped with head/tail retention;
+- active sessions can defer follow-up until the next monitor pass.
+
+## Configured MCP Servers
+
+`routes.mcp.mcp_routes` owns admin HTTP configuration for MCP servers:
+
+- list/add/reconnect/enable/disable/delete servers;
+- list tools and per-server tools;
+- update per-server disabled tool lists;
+- Google OAuth authorize/callback/manual exchange pages and generic Streamable HTTP OAuth redirect handling.
+
+`core.database.McpServer` persists transport, command, args, env, URL, enabled state, OAuth config, disabled tool names, and encrypted generic OAuth token/client state. `McpServer.env` is plaintext JSON in the database.
+
+`src.mcp_manager.McpManager` owns live connection state, stdio/SSE/Streamable HTTP transports, sessions, tool schemas, qualified names, and tool calls. HTTP route operations update both database state and live manager state where applicable. Streamable HTTP connects in a background task, can report `connecting` or `needs_auth`, and surfaces an authorization URL when the OAuth client flow redirects. Enabled configured servers connect concurrently at startup; each server has its own 20-second connection timeout and records `timeout` state without delaying siblings. The startup task has no second outer timeout.
+
+Stdio and SSE connection setup registers the session, exit stack, tool list,
+and status as one completed unit. If initialization or tool discovery fails
+before registration, the partial `AsyncExitStack` is closed so transports do
+not leak into later reconnect attempts.
+
+`src.agent_tools.admin_tools.do_manage_mcp()` is the agent/admin tool path for MCP config and is re-exported lazily through `src.tool_implementations` for compatibility. It is narrower than the HTTP routes: add is stdio-only, command values are checked against an allowlist/denylist before persistence, and enable/disable primarily flips DB config. `scripts/odysseus-mcp` is config-only; it reads and mutates database rows, redacts env values by default, and does not report live manager connection state.
+
+## Built-In MCP Servers
+
+`src.builtin_mcp` owns startup registration of built-in MCP servers unless `ODYSSEUS_DISABLE_MCP` is enabled.
+
+Python stdio built-ins:
+
+- image generation;
+- memory;
+- RAG;
+- email.
+
+The optional browser built-in uses `npx -y @playwright/mcp@latest --headless --caps vision`. It is cache-gated by checking npm's `_npx` cache for the requested package and falling back to `npx --no-install`; uncached/missing browser MCP is logged with install guidance and skipped rather than blocking startup or downloading packages at boot. Python built-ins are omitted from OpenAI function schemas because native/code-block paths already describe those capabilities; the browser built-in is exposed through MCP function schemas when connected.
+
+Built-in Python servers prepend the app root to inherited `PYTHONPATH` rather
+than replacing the environment, so container/dev site-packages remain visible
+on initial connect and automatic reconnect. They can be reconnected once on
+tool-call failure. User-configured MCP servers return the call failure instead
+of automatic reconnect.
+
+The built-in email MCP server is owner-aware when an owner is supplied by the
+caller or configured through `ODYSSEUS_MCP_EMAIL_OWNER` /
+`ODYSSEUS_EMAIL_OWNER`; if owner-scoped email accounts exist and no owner is
+available, email MCP fails closed instead of exposing global accounts. Other
+built-in servers remain process-global/admin trust-boundary tools unless their
+own subsystem spec says otherwise.
+
+## Agent MCP Exposure
+
+`McpManager` owns raw qualified tool calls named `mcp__{server_id}__{tool_name}`. It does not own admin, owner, public-user, or disabled-tool policy; callers must enforce policy before dispatch.
+
+Current exposure path:
+
+- `routes.mcp.mcp_routes` stores disabled tool names;
+- `src.agent_loop` loads disabled maps for prompts/schemas;
+- `McpManager.get_all_openai_schemas()` and prompt descriptions filter disabled tools;
+- `src.tool_index` indexes MCP prompt descriptions by manager generation;
+- `src.tool_security` blocks all `mcp__*` tools for non-admin/public users;
+- `src.tool_execution` dispatches received `mcp__*` calls to `McpManager.call_tool()`.
+
+Per-server disabled MCP tools currently hide tools from prompts/schemas while listings still return tools with disabled metadata. They are not a complete execution-time gate if a disabled qualified name reaches tool execution. Plan mode additionally asks `McpManager.plan_mode_blocked_mcp()` to hide write/unknown MCP tools and add qualified names to the runtime disabled set for that turn.
+
+After model-visible external/workspace context, arbitrary MCP actions classify fail-high and require an exact one-use approval unless a specific low-impact capability classification says otherwise. MCP results are marked external-untrusted for continuation security even when a call returns a failed status with remote payload.
+
+## Degraded And Platform Behavior
+
+- `app.py` starts the background monitor and MCP startup tasks asynchronously; MCP startup is non-critical to app readiness.
+- Configured MCP servers start concurrently with a per-server 20-second bound;
+  timeout state is stored per server and partial connection resources are
+  closed before returning.
+- Missing Python `mcp` dependency degrades attempted MCP connections to error status.
+- Missing or uncached browser NPX package is optional and log-only during built-in startup; startup should not perform an implicit package download.
+- Windows does not support POSIX PTY/tmux paths; streaming falls back to pipes or detached logfile behavior.
+- Docker images include selected shell dependencies and the Docker CLI, but host Docker socket access from inside the app container remains unavailable unless the operator explicitly enables `docker/host-docker.yml`/`ODYSSEUS_ENABLE_HOST_DOCKER=true` and mounts a real socket.
+- OAuth supports Google `installed` or `web` key shapes, a remote paste-back exchange page, and generic Streamable HTTP OAuth token storage through encrypted `McpServer.oauth_tokens`. Valid JSON values that are not objects are treated as empty token state and replaced by an object on the next write. Google and generic MCP OAuth share `src.mcp_oauth.REDIRECT_URI`, built from `OAUTH_REDIRECT_BASE_URL`, then `APP_PUBLIC_URL`, then `http://localhost:${APP_PORT:-7000}`, plus `/api/mcp/oauth/callback`. Reverse proxies, public domains, and Docker host-port mappings should set an explicit public base because container bind state cannot infer the browser origin.
+- `services.shell.service` remains a transitional/simple facade separate from route-level compatibility behavior.
+
+## Security And Provenance
+
+- Admin shell is intentional host command execution; do not expose shell routes or shell tools to regular users.
+- `_require_admin()` gates shell routes and MCP config routes. The internal-tool loopback can be admin-equivalent only after auth middleware validates the internal token and loopback client.
+- `_reject_cross_site()` currently applies to `/api/cookbook/packages`; `/api/shell/exec`, `/api/shell/stream`, package install, rebuild, and MCP write/OAuth routes do not call it directly.
+- Shell helper paths use argv-based SSH, reject option-like hosts, validate SSH ports through shared helpers, restrict remote venv characters, and allowlist package installs.
+- Non-admin/public tool policy blocks `bash`, `python`, file tools, `manage_mcp`, and all `mcp__*` tools.
+- MCP stdio server registration is arbitrary host process execution and is admin-only.
+- MCP OAuth key/token file paths supplied through routes are confined under `data/mcp_oauth`; generic Streamable HTTP OAuth token state is encrypted in the database.
+- Built-in MCP servers are local/admin trust-boundary tools and are not
+  automatically equivalent to owner-scoped HTTP route behavior. Email MCP is
+  the current exception with explicit owner filtering; other built-ins need
+  their own owner policy before being treated as scoped surfaces.
+- MCP output is external-untrusted tool output and arms the high-impact continuation gate when model-visible. Current MCP text output is still not centrally capped before model re-entry.
+
+## Testing Notes
+
+Current targeted coverage includes Windows PTY import degradation, PTY unsupported stream events, the cross-site helper, `ShellService` stream deadline behavior, background store/monitor basics, concurrent MCP startup, per-server timeout isolation and cleanup, MCP manager cache/reconnect args, built-in `PYTHONPATH` preservation, non-object generic OAuth-token storage recovery, MCP CLI JSON/env serialization, MCP common truncation helper, action intent shell verbs, and public blocked-tool fail-closed behavior.
+
+The shell/MCP audit ran the targeted venv subset with 78 passing tests and one warning.
+
+## Current Gaps
+
+- Decide whether `/api/shell/exec`, `/api/shell/stream`, package install, rebuild, and MCP config/OAuth writes should call `_reject_cross_site()` directly.
+- Add route-level shell exec/stream tests for admin gate, cross-site behavior, empty command, plain exec, timeout, PTY, tmux, and Windows detached fallback.
+- Add background job tests for launch isolation, output truncation, done/failed/timeout/died states, pending follow-ups, and result text.
+- Add route-level MCP CRUD/OAuth/disabled-tool tests with a fake manager and temp database.
+- Add hard per-server disabled MCP execution checks or document disabled tools as prompt/schema filtering only.
+- Make MCP tool indexing sensitive to disabled-map changes, not only manager generation.
+- Fix stale outer prompt/cache behavior when MCP disabled tools change.
+- Add one central truncation layer for MCP result text and images before model re-entry; untrusted-result marking and exact-action continuation approval are now implemented.
+- Decide whether `McpServer.env` and OAuth key files need masking, encryption, and chmod beyond admin-only access.
+- Decide whether built-in MCP servers should become owner-aware or remain documented as admin/global compatibility surfaces.
+- Decide whether optional browser MCP cache misses should surface in `/api/mcp` status instead of startup logs only.

+# Speech
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers speech behavior in:
+
+- app service initialization and route registration in `app.py`;
+- `services/stt/stt_service.py`;
+- `services/tts/tts_service.py`;
+- `routes/stt_routes.py`;
+- `routes/tts_routes.py`;
+- `src/upload_limits.py`;
+- settings defaults/cache in `src/settings.py`;
+- settings routes in `routes/auth_routes.py`;
+- model endpoint cleanup in `routes/model_routes.py`;
+- settings/tool aliases in `src/tool_implementations.py`;
+- frontend modules `static/js/voiceRecorder.js`, `static/js/tts-ai.js`, `static/app.js`, `static/js/chat.js`, `static/js/slashCommands.js`, `static/js/keyboard-shortcuts.js`, `static/js/settings.js`, and `static/index.html`;
+- optional dependency declarations in `requirements-optional.txt`;
+- runtime cache path `data/tts_cache/`;
+- tests covering speech service toggles, TTS speed/cache, STT temp cleanup, upload limits, settings scrubbing, and model endpoint cleanup.
+
+## Current Call Sites Include
+
+- chat mic/send button behavior;
+- browser and server STT recording paths;
+- chat message read-aloud buttons and streaming TTS queueing;
+- `/tts` slash command playback;
+- keyboard shortcut TTS activation;
+- admin/settings API writes and `manage_settings` aliases;
+- model endpoint deletion cleanup for `endpoint:<id>` speech providers.
+
+## STT
+
+`services.stt.STTService` owns speech-to-text provider behavior. `routes/stt_routes.py` owns `/api/stt/transcribe` and `/api/stt/stats`. `static/js/voiceRecorder.js` owns microphone capture, browser STT, server upload, and audio-attachment fallback.
+
+Provider runtime:
+
+- `disabled` returns unavailable and avoids provider calls;
+- `browser` is client-side only through Web Speech API and does not call `/api/stt/transcribe`;
+- `local` lazily imports `faster-whisper`, writes uploaded audio to a temporary WebM file, transcribes, and deletes the temp file in `finally`;
+- `endpoint:<id>` resolves a `ModelEndpoint` and posts `audio.webm` to `/audio/transcriptions` with model and optional language.
+
+Route behavior:
+
+- audio uploads are capped by the shared STT upload limit from `src.upload_limits`, including environment override validation;
+- empty uploads return a route error;
+- uploaded content type, extension, and magic bytes are not strongly validated today;
+- endpoint providers report optimistic availability and fail at request time if offline/misconfigured.
+
+Frontend behavior:
+
+- browser recording needs secure context and microphone permissions;
+- server transcription success inserts text into the input;
+- failed server transcription can attach the recorded audio file to chat instead; empty transcription shows a no-speech message.
+
+## TTS
+
+`services.tts.TTSService` owns text-to-speech provider behavior, speed parsing, cache behavior, and local/provider-specific synthesis. `routes/tts_routes.py` owns `/api/tts/stats`, `/api/tts/synthesize`, and cache clearing. `static/js/tts-ai.js` owns frontend playback, client object-URL caching, browser TTS, queueing, and streaming button state.
+
+Provider runtime:
+
+- `disabled` returns unavailable and avoids provider calls;
+- `browser` is client-side only through `speechSynthesis`;
+- `local` currently means Kokoro and requires `torch`, `kokoro`, `soundfile`, and CUDA/import availability;
+- `endpoint:<id>` resolves a `ModelEndpoint` and posts to `/audio/speech`.
+- unknown or non-string `tts_provider` values are treated as unavailable rather
+  than being parsed as endpoint strings.
+
+Route behavior:
+
+- `/api/tts/synthesize` supports binary `audio` responses and JSON `base64` responses;
+- binary responses choose WAV or MP3 MIME by audio magic bytes;
+- synthesis input is passed to the service as submitted and capped there;
+- malformed or nonpositive `tts_speed` falls back to `1.0`;
+- provider unavailable returns 503; failed synthesis/transcription generally returns route-level failure.
+
+## Settings, Endpoints, And Cache
+
+Speech providers are global settings under `data/settings.json`, with defaults in `src/settings.py`. Settings reads are scrubbed for non-admin callers, writes are admin-only, and `manage_settings` can change non-secret speech settings through aliases.
+
+Visible UI state is not complete: backend and JS speech settings exist, the TTS settings card is currently hidden, and the STT settings JS exits when its removed DOM nodes are absent.
+
+`routes.model_routes` clears `tts_provider` and `stt_provider` references when a referenced model endpoint is deleted.
+
+TTS cache behavior:
+
+- server cache lives under `data/tts_cache/`;
+- cache keys include provider, model, voice, safe speed, and text;
+- cache files are stored as MP3 or WAV;
+- route stats expose global cache state;
+- cache clear is global;
+- frontend TTS has a separate object-URL cache.
+
+`ODYSSEUS_TTS_CACHE_MAX_BYTES` bounds server cache growth and is forwarded by all Compose variants. The default is 500 MiB; invalid integers fall back to that default and values at or below zero disable eviction. After a cache write, enforcement scans only `.mp3`/`.wav`, ignores files that disappear or cannot be stated, and when over limit removes oldest-by-mtime entries toward 80% of the ceiling. Sort/stat/unlink failures are logged and do not fail synthesis.
+
+## Security And Provenance
+
+Speech routes rely on app-wide authentication and do not implement route-local admin or scope checks. Bearer-token callers that pass app auth can reach speech stats/synthesis/transcription/cache-clear surfaces using global speech settings.
+
+Endpoint providers send user audio or assistant text to configured `ModelEndpoint` URLs with optional bearer keys. Endpoint lookup is by configured endpoint ID and currently does not enforce per-request owner filtering. `ModelEndpoint.api_key` is encrypted at rest and forwarded only process-side.
+
+Microphone audio, uploaded audio, endpoint transcripts, and assistant text sent to TTS are untrusted/user/provider-visible data flows. Transcripts become user input; they are not trusted system instructions.
+
+TTS cached audio can contain sensitive assistant text rendered as speech. The cache is global, has no owner partition or TTL, and is served inline/base64 by POST responses without a dedicated generated-file route.
+
+## Degraded Behavior
+
+- Optional local speech packages may be absent.
+- Local STT can run CPU-only and tolerates missing/broken torch by falling back to CPU/int8 behavior.
+- Local TTS/Kokoro extras are declared as `kokoro==0.9.4` plus `soundfile` only for Python 3.11-3.12; Python 3.13+ intentionally skips them because Kokoro excludes those runtimes. Even where installed, local Kokoro remains unavailable without a CUDA-capable torch build/GPU.
+- External endpoint providers can be offline or misconfigured and may only fail at request time.
+- Browser `speechSynthesis`, `SpeechRecognition`, `webkitSpeechRecognition`, secure context, and microphone permissions can be absent.
+- Docker GPU overlays are passthrough-only and do not install speech engines by themselves.
+- Optional dependency errors and route error wording are not fully consistent across STT and TTS.
+
+## Testing Coverage
+
+Existing coverage includes speech service toggles, malformed/non-string TTS provider and speed handling, cache stats plus configured eviction/disable/file filtering/error handling, STT temp cleanup, direct upload limits, model routes, and settings scrubbing.
+
+Missing coverage includes route-level STT/TTS success and failure shapes, auth/API-token behavior, endpoint owner isolation, STT type/magic rejection, TTS request-size/no-store/cache privacy behavior, degraded optional dependency paths, and frontend recorder/TTS fallback states.
+
+## Current Gaps
+
+- Visible speech settings UI is incomplete relative to backend settings.
+- Speech routes need a deliberate API-token/scope policy.
+- Endpoint speech providers need owner-isolation or explicit global-settings documentation.
+- TTS cache needs privacy policy: owner partition, TTL, no-store response headers, or accepted global cache semantics.
+- STT upload validation needs content type/extension/magic-byte policy.
+- Browser/compare STT mic behavior needs a product decision or regression test because compare can force send-button visuals while shared empty-input logic can start recording.

+# Testing And Devops
+
+Last updated: dev@e71f8ce | 2026-08-25
+
+## Scope
+
+This spec covers development and validation surfaces in:
+
+- `tests/`, `tests/conftest.py`, `tests/*.mjs`, and `tests/bombadil-spec.ts`;
+- `tests/run_focus.py`, `tests/run_order_report.py`, `tests/_taxonomy.py`, `tests/TESTING_STANDARD.md`, and `tests/LAYOUT_INVENTORY.md`;
+- `pyproject.toml`;
+- `requirements.txt` and `requirements-optional.txt`;
+- `package.json` and `package-lock.json`;
+- `Dockerfile`, `docker-compose.yml`, `docker/gpu.nvidia.yml`, `docker/gpu.amd.yml`, `docker/host-docker.yml`, top-level standalone GPU compose files, and `docker/entrypoint.sh`;
+- `scripts/`, `scripts/odysseus`, `scripts/_lib/cli.py`, `scripts/_completion/*`, `scripts/pr_blocker_audit.py`, and `scripts/odysseus-*`;
+- GPU helper scripts `scripts/check-docker-gpu.sh` and `scripts/check-docker-amd-gpu.sh`;
+- `.github/` templates, workflows, and description-check scripts;
+- contributor workflow docs in `CONTRIBUTING.md` and `docs/pr-blocker-audit.md`;
+- platform launchers `launch-windows.ps1`, `launcher.py`, `Odysseus.spec`, `build-windows-portable.ps1`, `start-macos.sh`, `build-macos-app.sh`, and `update_windows.bat`;
+- setup/service files such as `setup.py`, `install-service.sh`, and `odysseus-ui.service`.
+
+## Test Runtime
+
+Pytest is configured in `pyproject.toml` with:
+
+- `testpaths = ["tests"]`;
+- `asyncio_mode = "auto"`;
+- marker and fast-lane/duration-reporting settings used by focused test runs.
+
+The expected local command uses the project venv:
+
+```bash
+./venv/bin/pytest <test path>
+```
+
+Activated-venv `python -m pytest <test path>` is equivalent. System/global `pytest` is not authoritative for this repo because installed versus stubbed dependencies can change collection behavior.
+
+`tests/conftest.py` inserts the repo root on `sys.path` and conditionally stubs missing heavy/runtime dependencies such as SQLAlchemy, FastAPI, Starlette, Pydantic, httpx, bcrypt, and pyotp. Tests that need real dependencies use explicit imports/skips. Tests that stub `sys.modules`, environment variables, globals, or parent packages must restore them with `monkeypatch` or an equivalent cleanup pattern.
+
+The suite currently contains roughly 728 `test_*.py` files. Treat that count as a moving source metric, not a target; focused regression tests are still preferred for narrow changes.
+
+Focused regression tests are preferred for narrow behavior changes. Broaden tests when touching shared contracts such as auth, owner filtering, OAuth/token custody, tool output, context building, provider calls, persistence, frontend rendering, or route/API shapes.
+
+`tests/run_focus.py` and `tests/_taxonomy.py` provide a local focused-run helper and category map. `.github/scripts/focused_test_guidance.py` maps changed files to suggested focused tests for PR review, while the configured full pytest CI job is authoritative. `tests/TESTING_STANDARD.md` documents expectations for targeted validation, and `tests/LAYOUT_INVENTORY.md` records the test-suite layout. CLI tests live under `tests/cli/`.
+
+## JS And UI Tests
+
+The repo has no frontend build pipeline, npm test script, or type-check script. `package.json` owns Node dependencies for Bombadil and the Anthropic SDK, and `package-lock.json` owns npm integrity/version state.
+
+Current frontend/JS validation includes:
+
+- pytest wrappers that run Node snippets and usually skip when `node` is missing;
+- direct `.mjs` regressions under `tests/`;
+- `tests/bombadil-spec.ts`, which requires npm-installed Bombadil dev dependencies and a running/browser-capable UI workflow when used.
+
+Use `node --check static/js/<changed-file>.js` for syntax checks on changed JS files when applicable. This is not a full module-graph, browser-global, or DOM integration check.
+
+## Dependencies
+
+`requirements.txt` owns core runtime and test dependencies, including pytest, pytest-asyncio, MCP, Chroma HTTP client, fastembed, qrcode, and core parsing/search/calendar dependencies.
+
+`requirements-optional.txt` owns optional feature dependencies:
+
+- `faster-whisper` for local STT;
+- `kokoro==0.9.4` and `soundfile` for local TTS on Python 3.11-3.12 only; Kokoro is deliberately skipped on Python 3.13+ because its package metadata excludes those runtimes, and a CUDA-capable torch/GPU is still required at runtime;
+- `ddgs` for DDG library support, while provider code can fall back to HTML scraping;
+- `PyMuPDF` for PDF forms/rendering with AGPL implications for a network-served app;
+- `markitdown[docx,pptx,xlsx,xls]` for Office/EPUB extraction, pinned to a release older than 30 days.
+
+Optional dependencies should produce clear degraded behavior when absent unless intentionally promoted to core. MarkItDown and PyMuPDF already have focused degraded-path coverage; local STT missing-`faster-whisper` behavior is a remaining coverage gap. Core runtime requirements include `httpx2` where compatibility tests depend on it. The official Docker image additionally installs `libmagic1` plus `python-magic==0.4.27` for content-based upload MIME sniffing; that pairing is image-owned because `python-magic` needs the system shared library at import time.
+
+Chroma has two compatibility modes:
+
+- Docker uses a separate `chromadb` service and core `chromadb-client`/`fastembed`;
+- native macOS setup removes conflicting `chromadb-client` and installs full `chromadb`.
+
+Vector features should fail fast or degrade to unhealthy/keyword fallback when the service is unavailable.
+
+## Docker Runtime
+
+Docker Compose is the primary deployment path:
+
+```bash
+docker compose up -d --build
+docker compose ps
+docker compose logs --tail=120 odysseus
+```
+
+`docker-compose.yml` starts Odysseus, ChromaDB, SearXNG, and ntfy. It binds services to loopback by default through `APP_BIND`, `CHROMADB_BIND`, and `NTFY_BIND`, persists configurable `APP_DATA_DIR`/`APP_LOGS_DIR`, SSH identity, HuggingFace cache, and user-local Python installs, and gives the Odysseus container host-loopback reachability through `host.docker.internal`.
+
+Compose variants forward `ODYSSEUS_TTS_CACHE_MAX_BYTES`, defaulting in the service to 500 MiB, and run the mounted `scripts/migrate_searxng_settings.py` helper so retained SearXNG YAML gains default inheritance without replacement. The helper preserves file metadata and formatting where possible and writes atomically; migration failure is non-fatal to the wrapper command. MCP OAuth callback setup follows `OAUTH_REDIRECT_BASE_URL`, `APP_PUBLIC_URL`, or the launcher/bind `APP_PORT`, so externally remapped deployments should set a public base explicitly.
+
+`Dockerfile` builds a Python 3.14 slim image with Node/npm, tmux, OpenSSH client, git/cmake, the pinned Docker CLI `29.6.2`, `gosu`, `libmagic1`, and the image-only `python-magic` wrapper.
+
+`docker/entrypoint.sh` owns writable path ownership repair, PUID/PGID user/group creation and privilege drop, optional host-Docker socket group handling, vLLM/CUDA environment defaults, idempotent `setup.py`, and final uvicorn execution.
+
+Docker does not mount the host Docker socket by default. Mounting it would grant powerful host access and is outside the default trust boundary. `docker/host-docker.yml` is the explicit opt-in overlay and sets `ODYSSEUS_ENABLE_HOST_DOCKER=true`; tests guard that the default and GPU compose files do not enable host Docker accidentally.
+
+## GPU And Platform
+
+Base `docker-compose.yml` plus `docker/gpu.nvidia.yml` or `docker/gpu.amd.yml` are the GPU source of truth. Top-level `docker-compose.gpu-nvidia.yml` and `docker-compose.gpu-amd.yml` are standalone mirrors for stack-management UIs that accept one compose file. `tests/test_gpu_compose_standalone.py` guards drift between those forms.
+
+GPU overlays pass host devices/runtime flags only. They do not install CUDA/ROCm userspace or serving engines; those are installed later through Cookbook/dependency flows.
+
+NVIDIA helper behavior:
+
+- `scripts/check-docker-gpu.sh` diagnoses passthrough;
+- it is read-only by default;
+- toolkit install and `.env` edits require explicit user flags and successful passthrough checks.
+
+AMD helper behavior:
+
+- `scripts/check-docker-amd-gpu.sh` is read-only;
+- it prints expected `COMPOSE_FILE`/`RENDER_GID` values and verifies `/dev/kfd`/`/dev/dri` visibility.
+
+Native platform launchers:
+
+- `launch-windows.ps1` requires Python 3.11+, creates `venv`, installs `requirements.txt`, runs `setup.py`, discovers per-user Git Bash installs where possible, warns when Git Bash is missing, and starts uvicorn on port 7000 by default.
+- `launcher.py`, `Odysseus.spec`, and `build-windows-portable.ps1` own the PyInstaller-style portable Windows launcher path, including app-root/data-dir differences covered by `src.runtime_paths`.
+- `start-macos.sh` reads `.env`, defaults to port 7860 to avoid AirPlay conflicts, prefers Homebrew arm64 Python, installs/tolerates Homebrew Cookbook deps, handles Chroma package conflicts, starts ChromaDB for native runs, runs `setup.py`, and starts uvicorn.
+- `build-macos-app.sh` builds a launcher app around the existing repo venv and logs to `logs/odysseus-app.log`.
+- `update_windows.bat` owns the tested Windows Docker update flow.
+
+## Scripts And CLI
+
+`scripts/odysseus` is the umbrella dispatcher for executable `scripts/odysseus-*` commands. It discovers subcommands and executes them through the project venv Python when available.
+
+`scripts/_lib/cli.py` owns shared CLI behavior:
+
+- repo-root importability;
+- quiet logging;
+- JSON output and `--pretty`;
+- `--version`;
+- common parser scaffolding;
+- exit handling.
+
+`LOG_LEVEL` is the shared process logging toggle. CLI helpers default it to
+`WARNING` to keep JSON command output clean; the web app defaults it to `INFO`
+and applies it to root, console, rotating-file, and direct-uvicorn logging.
+Shell completions in `scripts/_completion/` introspect CLI `--help` output through the venv and cache subcommands.
+
+`scripts/odysseus-*` provide local CLI surfaces for backup, calendar, contacts, Cookbook, docs, gallery, logs, mail, MCP, memory, notes, personal docs, presets, research, sessions, signatures, skills, tasks, theme, and webhooks.
+
+When route/API behavior changes, check whether a matching CLI script depends on the old shape. There is no central CLI scrubber: each credential/log/mail/task/backup/MCP/webhook script owns its own sensitive-output behavior.
+
+## GitHub Metadata
+
+`.github/` owns issue/PR templates, a copyable PR review template, description-check workflows, security/governance workflows, Docker publishing, and CI. Current CI runs on pushes to `main` and `dev` plus pull requests, compiles Python with `python -m compileall`, syntax-checks first-party JS with `node --check`, emits focused-test guidance for changed code, and runs the configured `python -m pytest -q` scope as an authoritative failing job; pytest still skips documentation-only changes.
+
+`CONTRIBUTING.md` owns the branch model: PRs target `dev`; `main` is the curated user-running branch fast-forwarded from stable `dev` commits. Contributors who accidentally target `main` should retarget the PR base without rebasing.
+
+PR description checks:
+
+- run on `pull_request_target`;
+- check out only base-branch `.github/scripts`;
+- skip bot PRs;
+- require Summary, Linked Issue, Type of Change, duplicate-search checklist, and substantive How to Test content as the hard description gate;
+- classify changed paths as docs-only, tooling, backend/runtime, or UI-sensitive from GitHub's file API while executing only base-branch checker code;
+- treat app-run and screenshot/clip checkboxes as author attestations, require an actual media link/attachment for UI-sensitive changes, and report runtime/visual evidence gaps separately from malformed descriptions;
+- serialize mergeability labeling behind description validation and avoid granting `ready for review` to drafts or changes with outstanding runtime/visual evidence;
+- update a bot comment and reconcile `ready for review`, `needs work`, `needs runtime validation`, and `needs visual evidence` labels where those labels exist.
+
+Issue description checks:
+
+- validate bug or feature sections based on labels;
+- require bug reports to include the exact 12-character revision/date shape produced by `git show -s --abbrev=12 --format='%h (%cs)' HEAD`;
+- flag unfilled dropdown placeholders such as `-- Please Select --`;
+- route public vulnerability reports toward GitHub Security Advisories;
+- update a bot comment and swap status labels;
+- remove the workflow-owned review label when an issue closes so closed issues do not retain stale readiness state.
+
+Security metadata includes container Trivy SARIF upload, Dockerfile lint, dependency review, secret scan, workflow security linting, GitHub default-setup CodeQL, Dependabot metadata, and hardened PR/issue description checks that avoid unsafe head-branch execution. `docs/security-ci.md` documents CodeQL as a dynamic GitHub default-setup workflow; the repo should not add a checked-in CodeQL workflow while that default setup is active.
+
+`scripts/pr_blocker_audit.py` is a read-only maintainer/contributor triage helper documented in `docs/pr-blocker-audit.md`. It can fetch or ingest open PR metadata, estimate hot files and possible duplicate groups, and emit Markdown, JSON, or terminal reports. Its duplicate/blocker output is advisory, not an authority that a PR is blocked.
+
+Before posting PRs or issues, compare drafts against current templates on latest `main` or current `dev` as appropriate for the target. Keep unpublished drafts and raw related-search exports out of tracked implementation specs unless intentionally promoted.
+
+## Artifacts And Secrets
+
+- Do not read `.env*` files unless a user explicitly asks for a controlled setup/debug step; never print their values.
+- Backup files, logs, CLI JSON, and raw issue/PR search exports can contain sensitive local data.
+- Do not commit raw GitHub JSON unless there is an explicit maintainer reason. Prefer compact Markdown reports when publishing analysis.
+- Specs are implementation truth. Planning, research, branch notes, and draft reports belong in tracked project docs when promoted.
+
+## Development Checks
+
+Common local checks:
+
+```bash
+./venv/bin/pytest tests/path.py::test_name
+./venv/bin/python -m py_compile app.py routes/*.py src/*.py
+node --check static/js/changed-file.js
+docker compose config
+docker compose up -d --build
+docker compose logs --tail=120 odysseus
+```
+
+Run the app for user-facing or integration changes. Unit tests and syntax checks do not replace end-to-end verification for UI, Docker, provider, auth, or routing behavior.
+
+## Shared Test Helpers
+
+`tests/helpers/` owns reusable test scaffolding. `cli_loader.load_script()` loads CLI files without running their `main()` entrypoint. `db_stubs` owns small DB stand-ins for tests that should not import a real app database. `import_state` owns conservative `sys.modules` and parent-module-attribute restoration for tests that install fake modules or import route files under alternate stubs. `tests/README.md` documents helper conventions and review expectations.
+
+## Current Gaps
+
+- Fresh install smoke coverage across Linux native, Docker, macOS native/app, Windows native, WSL/Git Bash, missing Node/npm, missing Chroma service, and GPU overlays remains a roadmap item.
+- There is no frontend build/type-check/npm test pipeline.
+- CI now covers Python compile, first-party JS syntax, focused-test guidance,
+  and pytest smoke; it does not cover Docker compose validation, launcher smoke
+  tests, browser/module-graph execution, or platform installs.
+- Optional dependency behavior is broad; remaining gaps include local STT missing-`faster-whisper`, Kokoro's Python/GPU degraded matrix, and provider/OAuth combinations not covered by focused tests.
+- GitHub description-check scripts and `scripts/pr_blocker_audit.py` need continued local fixtures for section parsing, placeholder stripping, label swaps, workflow-safe behavior, and duplicate/hot-file heuristics.
+- Spec bootstrap rules lack meta tests for reading `_readme.md`, spec shape, `.env*` handling, draft/report placement, and shared helper conventions.
+- NVIDIA helper install/`.env` mutation paths and real Docker/GPU startup are not covered by local tests.
+- Bash/Zsh completion behavior is not covered.
+- There is no canonical full-suite known-failing/flaky ledger.
+- There is no central CLI redaction/sensitive-output regression matrix across backup, logs, mail, MCP, tasks, and webhook scripts.
+- Dependency/image pinning policy is mixed: Python requirements are mostly unpinned, SearXNG is pinned, Chroma image currently uses `latest`, npm uses a lockfile, and browser MCP uses cache-gated `@playwright/mcp@latest`.

Subject: [PATCH 175/180] fix(deps): switch psycopg2 to psycopg2-binary (#5937)

Building psycopg2 from source needs libpq-dev/pg_config, which isn't
in the Docker image or most dev hosts, so pip install silently fails
and Postgres users hit ModuleNotFoundError at import time.

Subject: [PATCH 177/180] fix(discovery): cache a successful but empty
 Tailscale lookup (#6228)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The host cache was gated on the list being non-empty, so "queried fine, no
eligible peers" looked exactly like a cold cache and every caller paid for
another `tailscale status --json` — a subprocess with a 5s timeout.

Gate on the timestamp instead. Failures still leave the timestamp unset, so a
missing binary, a non-zero exit or unparseable output stays retryable rather
than being cached for the full TTL.

Subject: [PATCH 179/180] Merge commit from fork

* fix(security): stop API tokens reaching privileged agent tools

A bearer API token resolves to the human who minted it, and minting is admin-only, so every owner-keyed privilege check in the agent path answers "admin". A token issued for a narrow integration therefore reached bash and python with the authority of the account that created it.

Three independent routes to that sink, each closed here.

The token could answer its own tool-approval prompt. An approval records that a person authorized one dangerous action, and a token cannot make that statement, so /api/chat_stream now refuses an approval resume from a bearer caller.

The chat-session grant was reconstructable from caller-supplied message metadata. Two routes persist a metadata blob on the caller's behalf, so the shape of a resolved approval card could be written straight into a transcript and was then read back as authority. The server now signs the grant when it resolves an approval and verifies that signature when reading it back, binding it to the chat and the approval it was issued for. Both routes also drop server-owned keys from an inbound blob.

A run driven by a token inherited its owner's tool set. Such a run is now capped at the non-admin policy regardless of who minted the credential, which holds even where no approval is raised at all.

The human path is unchanged: a browser session still receives the prompt, still approves, and a granted chat-session scope still carries to later turns in that chat.

Scope enforcement across the wider route surface is a separate gap and is not addressed here.

* fix scoped chat delegation boundaries

* fix(auth): reject malformed chat approval signatures

Subject: [PATCH 180/180] Merge commit from fork

* fix(security): keep agent file tools out of the app state directory

The agent's read tools (read_file, grep, glob, ls) resolved model-supplied
paths against a root list whose first entry was the whole data directory.
That directory holds the session store, the auth database, the app
encryption key and the settings file, so prompt-injected content could ask
for any of them. No approval prompt stood in the way: reads are classified
read_workspace and pass the untrusted-context gate untouched, which is
correct for reading a workspace and wrong for reading the app's own state.

The agent gets data/agent_workspace/ instead, and the subprocess cwd and
HOME move with it so bash and read_file agree on where scratch files live.

The deny itself is a property of the path, not of the root it arrived
through, because three routes reach the same bytes and closing only the
first leaves the other two working:

  - the default root list
  - a workspace bound at or above the data directory, which vet_workspace
    accepted and chat_routes auto-binds from a path named in the message
  - a tool_path_extra_roots setting covering the data directory

_resolve_search_root also returned the workspace root unchecked when the
path was empty, so a bare ls enumerated the directory whatever the deny
list said. It now resolves that case through the same guards.

A containment rule rather than a filename deny list, so state files added
later are covered without anyone remembering to list them, and so a user's
own settings.json or app.db inside a real workspace is not caught.

Four directories of user content stay readable, because the application
hands their paths to the model and tells it to open them: the chat upload
manifest, downloaded mail attachments, personal docs (which covers the
runbook) and personal uploads.

* fix: enforce state deny during recursive file search

* fix: bound protected filesystem searches

* fix(security): reject inode aliases and workspace redirects

* fix(security): harden partitioned agent searches

* fix(security): report fallback worker exits promptly

* fix(security): clean up search readers and retain relative data roots
