* fix(chat): warn before "regenerate" permanently deletes later messages
Both "regenerate" entry points — the per-message footer's ↻ "Regenerate
from here" button, and the vision editor's "Regenerate message" button —
call POST /api/session/{id}/truncate, which does a real, permanent SQL
delete of every message after the point clicked, then generates a new
reply. Clicking either on anything but the very last exchange did this with
zero warning: the button's own label doesn't say it also erases the rest
of the conversation, and neither button visually signals it's destructive
differently from any other message-footer action.
Caught live: a mis-click destroyed a real conversation with no way to
recover it (no backup covered the affected window). This adds a
confirmation prompt — via the existing uiModule.styledConfirm — whenever
the action would delete more than just the message(s) being regenerated,
stating the exact count of messages that would be lost. Regenerating the
most recent exchange (the everyday case, nothing exists after it) is
unaffected and still proceeds with zero friction.
New test: tests/test_regenerate_truncate_warning_js.py — drives the real
regenerateFrom/resendUserMessage functions under Node with a fake message
list DOM, confirming: the last-exchange case never prompts and truncates
directly; an earlier case prompts with the correct count; cancelling
aborts before any network call; confirming proceeds with the correct
keep_count. Also fixed a pre-existing, unrelated gap this surfaced while
verifying the full suite: test_pr6020_browser_review_regressions.py's
Node harness never stubbed `navigator` at all (sessions.js reads
navigator.platform at module load) — a gap on origin/dev itself, not
caused by this branch's diff, using the same Object.defineProperty fix
already applied on #6019/#6148 for the sibling issue there (Node 21+'s own
getter-only navigator global, not relevant to this specific failure but
the same defensive pattern).
Verified: full pytest suite in-container, 5798 passed / 11 pre-existing
unrelated failures (README/docs/agent-loop baseline) / 0 new.

* test(chat): cover plain resend after dev's replace-by-default change
dev made plain resend (no options) replace from the clicked turn by
default, with append-only resend opt-in via { append: true } (see
test_resend_message_nondestructive.py). The footer "Resend message"
button calls resendUserMessage(el) with no options, so it now truncates
everything after the clicked turn and goes through this PR's warning.
Replace the old "plain resend never prompts" test, which assumed the
previous append-by-default behavior, with one asserting that plain
resend on an earlier pair prompts with the right count, and one
asserting that explicit append-only resend never truncates or prompts.
Also resolve ui.js/sessions.js through the same cache-busting query
string chat.js imports them with. ES modules cache by full URL, so the
harness's unversioned import of ui.js was a second module instance and
its uiMod.styledConfirm stub never reached the instance chat.js calls.

* fix(chat): warn before an edit deletes later messages; offer to fork instead
Sending an edited user message truncates the chat at that message, the
same unrecoverable server-side delete as regenerate and resend, but did
it with no prompt. It now goes through the same confirmation, worded for
the action ("Sending this edit will also permanently delete the N
messages after it"). Cancelling leaves the editor open with the draft.
The confirmation for all three actions (regenerate, resend, edit) also
offers "Fork from here": it forks the chat just before the user turn,
switches to the new chat, and replays the action there (the same message,
or the edited text), leaving the original chat untouched. forkFrom now
shares the same fork helper.
Tests drive the real editUserMessage Send handler under Node and cover
the edit prompt (count, cancel, last-message no-prompt) and the fork
choice for each action (fork keep_count, no truncate, replayed text).

* fix(chat): cut and fork a chat by message id, not loaded-page position
Regenerate and edit sent keep_count, the clicked message's position among
the messages loaded in the page. A long chat loads only its newest messages
until the user scrolls up, so that position is smaller than the real one and
the truncate deleted real messages above the clicked one (regenerating the
latest reply in a ~50-message chat removed about a dozen earlier messages).
Resend already sent before_msg_id; regenerate and edit now do the same.
The fork options this PR adds had the same flaw. Fork now accepts
before_msg_id (fork before that message) and through_msg_id (include it),
resolved against the stored messages; keep_count stays as the fallback for a
message that has no id yet.

* fix(chat): keep a regenerated turn's message id current; stop on a refused cut
Regenerate keeps the original user bubble on screen and resubmits its text
without drawing a new bubble. The resubmitted message is a new DB row, but
the bubble kept the deleted row's id, so the next regenerate's cut was
refused (404) and the page sent the turn anyway, stacking a second reply.
The stream now reports the saved user message's id (user_message_saved),
which the page attaches to the user bubble, or to the bubble a regenerate
kept. Regenerate and edit stop with an error when the server refuses the
cut instead of sending.

* test(chat): name the buttons in words instead of symbols
CONTRIBUTING asks for no Unicode emoji in UI or code; the test comments
used the regenerate and pencil glyphs to name buttons.

* refactor(chat): share the fork-and-send step across edit, resend and regenerate

* fix(chat): pass the regenerate fork its attachment ids explicitly
Resend already hands its collected file ids to _forkAndSend; regenerate
relied on the earlier _pendingRegenAttachments assignment. Pass _regenIds
too so both fork paths read the same, and check the hand-off in the
regenerate tests.

* test(chat): assert fork choices keep the user message's attachments
Run regenerate and resend's "Fork from here" against a user message with
an uploaded file and check that the send fired in the fork carries its
file id, replacing the source-text check. chat.js exposes a read-only
_pendingRegenAttachmentIds() for this, like cookbook-hwfit.js's test hooks.

* fix(history): reject implicit and coerced truncation targets
* fix(history): reject falsy non-string message IDs; drop redundant keep_count guard
The or-chain used to resolve before_msg_id / message_id evaluated
falsy non-strings (False, 0) to '' before the isinstance(…, str) check
was reached, so they silently bypassed type validation. Replace the
chain with explicit presence-aware logic that falls through on None or
empty string (preserving alias semantics) but rejects any other
non-string value with HTTP 400.
Also remove the now-tautological 'if keep_count >= 0:' guard, which
is always True after the negativity check introduced in the parent
commit. The DB block is unconditional and indented accordingly.
Tests: add {'before_msg_id': False}, {'before_msg_id': 0},
{'message_id': 0} to the parametrised rejection suite.

* feat(settings): opt-in reasoning effort for utility model calls
Add utility_reasoning_effort (empty = provider default) and let utility
calls inherit a chat session's effort only on that session's matching
endpoint+model route. Explicit caller effort wins; otherwise the utility
setting wins over session inheritance on utility-chain routes. Resolve
the chain and setting per user and validate levels against model evidence.
No-session work uses the setting only, with no chat-effort crossover.
- src/utility_effort.py owns effort_for_call and candidate_effort_factory
- remove global effort fill from llm_call/llm_call_async; utility call
sites pass effort explicitly, so unrelated calls on the same route do
not pick it up
- wire auto-title, memory/persona/skill extraction, memory suggest/import/
audit, compaction, auto-sort, and per-owner background task candidates
- wire no-session email writing-style, summary, and translation calls,
plus skills evaluation, necessity/retrieval audits, and improvement
- deliberately exclude email replies because thinking_mode='off'
- add the optional candidate_request_factory to llm_call_async_with_fallback
- add sync llm_call reasoning_effort and include it in the cache key
- show the Utility Model effort selector only for advertised levels
Fixes#6569
* fix(utility): exclude email replies and support inherited effort in settings
Pass reasoning_effort='' to task_llm_call_async for scheduled reply drafting to honor the email reply exclusion. In AI settings, resolve the effective Default Chat endpoint and model when Utility is set to 'Same as chat' so supported reasoning effort levels can be selected.
* feat(utility): support same-as-chat effort and session model fallback in compaction
In AI settings, show 'Same as chat' as the default effort option when Utility Model is inherited, and support an explicit 'Provider default' (off) override. Pass the active session fallback in context compaction callers so compaction shares the live chat session's model and reasoning effort for maximum prompt/KV cache affinity.
* fix(settings): clarify chat effort inheritance and keep option visible
Label inherited effort as 'Same as chat (when supported)' and mention
cache affinity and latency speedups in the help text. Ensure the effort
control remains visible when the utility model is set to 'Same as chat'
even if the default chat model lacks advertised reasoning levels, and
populate candidate levels across configured endpoints so the user can
configure effort or keep provider default.
* feat(settings): per-fallback reasoning effort for utility model
Each utility fallback row gets an Effort select, shown only when the
selected model advertises reasoning levels. The choice is stored as
reasoning_effort on the utility_model_fallbacks entry and sent only to
that candidate; an empty value means provider default.
* fix(utility): transmit reasoning effort in non-streaming calls

* 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(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

Slice 2d of the route-domain reorganization (#4082/#4071, per
specs/architecture-runtime-inventory.md §6.3). Moves history_routes.py into
routes/history/, 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, and memory #5007 slices) so that `import
routes.history_routes`, `from routes.history_routes import X`,
`importlib.import_module(...)`, and the `import ... as history_routes` +
`monkeypatch.setattr(history_routes, ...)` pattern used by
test_history_compact_tool_calls.py / test_fork_session_metadata.py all
operate on the same module object the application uses.
The canonical module does NOT depend on the shim — routes/history/
history_routes.py imports only from core/, src/, and routes.session_routes
(a sibling route module whose old import path stays valid via its own shim
when session is migrated later).
Three source-introspection test sites repointed to the new canonical path:
- test_history_db_fallback_hidden.py
- test_history_order_by_timestamp_regression.py
- test_model_helper_owner_scope.py
Adds tests/test_history_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 4351 passed, 3 skipped.
