* fix(upload): honor no-login mode after account setup
* ci: refresh checks against the current dev base
* test(upload): add regression tests for unconfigured auth and no-login POST
* fix(upload): fail closed on missing auth_manager and preserve cross-user isolation
Enforce strict cross-user isolation so that authenticated users cannot access
files owned by other accounts when app.state.auth_manager is absent or None.
Fail closed with HTTP 503 for non-loopback requests when AUTH_ENABLED=true and
authentication infrastructure is unexpectedly unavailable, while preserving
intended single-user mode (AUTH_ENABLED=false) and intentional first-run setup
mode (auth_manager.is_configured=False).
* fix(upload): eliminate fail-open paths for unconfigured manager and loopback transport
- Eliminate early return on unconfigured auth_manager (Finding A): fail closed with HTTP 401 Setup required
- Eliminate loopback transport bypass when auth_manager is missing (Finding B): fail closed with HTTP 503
- Enforce strict ownership isolation: non-owners and legacy ownerless uploads require verified administrator access
- Add regression suites in tests/test_upload_no_login.py covering Finding A, Finding B, bearer tokens, and ownerless files
- Explicitly set AUTH_ENABLED=false for unauthenticated tests in tests/test_upload_routes_owner_scope.py
* fix(upload): prevent delegated API tokens from inheriting admin privileges and enforce upload scopes
- Prevent delegated bearer API credentials from inheriting interactive administrator privileges over other users' files or legacy ownerless files.
- Enforce granular upload scopes for delegated credentials: chat and documents:write for upload creation and vision OCR editing; chat, documents:read, and documents:write for downloads, thumbnails, and vision OCR reads.
- Reject requests with missing token owners or reserved sentinel identities (api, demo, system, internal-tool) with 403 Forbidden.
- Add comprehensive regression tests in tests/test_upload_no_login.py verifying delegated token scope isolation, sentinel rejection, owner isolation, and untouched OCR state on rejected edits.

* 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.
36 passed, 0 failed (Python 3.14.4 / pytest 9.1.1).
