feat(07.1): session revocation on privilege change — CR-01/CR-02/CR-03

- revoke_all_refresh_tokens: add skip_token_hash optional param (exclude current session while revoking others) - change_password, enable_totp, disable_totp: call revoke with skip hash derived from refresh cookie; return sessions_revoked in response and write to audit log metadata_ - 3 new tests: test_{change_password,enable_totp,disable_totp}_revokes_other_sessions — all PASSED; 373 total passing, 0 regressions - Frontend toasts: SettingsAccountTab + TotpEnrollment show "Other sessions have been terminated." when sessions_revoked > 0 - Companion fixes: rate_limiting get_client_ip refactor, deps/auth.py request.state.current_user, locustfile refresh-token task removal - Version bump: 0.1.0 → 0.1.1 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

+### Phase 7.1: Security: session revocation on privilege change (CR-01..03) (INSERTED)
+
+**Goal**: Fix the three missing session-revocation calls in `backend/api/auth.py`: `change_password`, `enable_totp`, and `disable_totp` must all call `revoke_all_refresh_tokens()` (excluding the current session). Add `sessions_revoked` to their response shapes and a frontend toast when other sessions are terminated.
+**Mode:** quick
+**Depends on**: Phase 7
+**Requirements**: CR-01, CR-02, CR-03
+
+**Plans**: 2 plans
+
+**Wave 1** — Backend: service + API changes
+
+- [ ] 07.1-01-PLAN.md — Add skip_token_hash param to revoke_all_refresh_tokens + wire revoke into change_password, enable_totp, disable_totp with sessions_revoked response + audit log
+
+**Wave 2** *(blocked on Wave 1)*
+
+- [ ] 07.1-02-PLAN.md — Tests (3 new test_*_revokes_other_sessions) + frontend toast in SettingsAccountTab.vue + TotpEnrollment.vue
+
+---
+
+### Phase 7.2: Security — JTI Claim + Redis Access-Token Revocation (INSERTED)
+
+**Goal**: Add a `jti` (JWT ID) claim to every issued access token. In `get_current_user`, check `redis.get("jti_revoked:{jti}")` and raise 401 if set. Add `revoke_access_token(jti, ttl)` helper called from `change_password`, `enable_totp`, `disable_totp`, and admin account deactivation. Closes the 15-minute window where a revoked session's live access token remains valid.
+**Mode:** quick
+**Depends on**: Phase 7.1
+**Requirements**: Tracked in `.planning/codebase/CONCERNS.md` §"No JTI Claim and No JTI Revocation in Redis"
+
+**Status:** Not planned yet
+
+---
+
+### Phase 7.3: Security — ES256 Algorithm Upgrade (INSERTED)
+
+**Goal**: Replace HS256 with ES256 (ECDSA P-256) for JWT signing. Generate a P-256 key pair; store private key in `JWT_PRIVATE_KEY` env var, public key in `JWT_PUBLIC_KEY`. Update `create_access_token` and all `decode_*` functions. Rotate all active refresh tokens on first boot after deploy. A leaked public key cannot forge tokens.
+**Mode:** quick
+**Depends on**: Phase 7.2
+**Requirements**: Tracked in `.planning/codebase/CONCERNS.md` §"JWT Algorithm Downgrade: HS256 Instead of ES256"
+
+**Status:** Not planned yet
+
+---
+
+### Phase 7.4: Security — Token Fingerprinting / Token Binding (INSERTED)
+
+**Goal**: Add a `fgp` (fingerprint) claim = `hmac(key, User-Agent + Accept-Language)[:16]` to every issued access token. In `get_current_user`, recompute the fingerprint from the request headers and compare with `hmac.compare_digest`. Limits replay of stolen access tokens to the original device/browser context.
+**Mode:** quick
+**Depends on**: Phase 7.3
+**Requirements**: Tracked in `.planning/codebase/CONCERNS.md` §"No Token Fingerprint / Token Binding"
+
+**Status:** Not planned yet

+# Phase 07 Plan 04: Celery Retry Harness + POST /classify Re-queue Summary
+
+## One-liner
+
+Celery exponential-backoff retry harness (30s/90s/270s) via `_ClassificationError` sentinel + MaxRetriesExceededError nested catch, and `POST /classify` converted from synchronous classification to Celery re-queue.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Celery retry harness + _ClassificationError + classification_failed writeback | e9ee5d4 | document_tasks.py, test_document_tasks.py |
+| 2 | POST /api/documents/{id}/classify → re-queue Celery | 63cd707 | documents.py, test_documents.py |
+
+## What Was Built
+
+### Task 1: Celery retry harness (D-09 / D-10)
+
+`backend/tasks/document_tasks.py` was refactored to implement the self-healing retry loop:
+
+- `class _ClassificationError(Exception)` — sentinel raised by `_run()` when `classifier.classify_document()` fails; escapes `asyncio.run()` and is caught by the outer sync task
+- `async def _mark_classification_failed(document_id)` — writes `doc.status = "classification_failed"` after all retries exhausted; called via `asyncio.run(...)` from the `MaxRetriesExceededError` handler
+- Task decorator changed to `@celery_app.task(name=..., bind=True, max_retries=3)`
+- Retry loop: `except _ClassificationError as exc` → `countdowns = [30, 90, 270]` → `raise self.retry(exc=exc, countdown=countdown)`
+- `MaxRetriesExceededError` caught in a **nested** `try/except` inside the `_ClassificationError` handler (not as a sibling `except`) because `raise self.retry()` raises `MaxRetriesExceededError` during exception handling context
+
+**Critical architectural decision:** The nested catch was required. If `MaxRetriesExceededError` were a sibling `except` block after `except _ClassificationError`, Celery's `self.retry()` call raising `MaxRetriesExceededError` inside the `_ClassificationError` handler would propagate past it without being caught.
+
+### Task 2: POST /classify re-queue (D-11)
+
+`backend/api/documents.py` classify endpoint was refactored:
+
+- Removed: `await classifier.classify_document(session, doc_id, topic_names)` and the topics response
+- Added: `doc.status = "processing"`, `await session.commit()`, `extract_and_classify.delay(str(doc.id))`
+- Returns: `{"document_id": str(doc.id), "status": "processing"}` with HTTP 200
+- Ownership check retained inline (no `_get_owned_doc` helper existed; plan said to replicate if absent)
+- `body: dict = {}` parameter removed (no longer needed since topics are written by the Celery task)
+
+## Test Coverage
+
+### Promoted from xfail:
+- `test_document_tasks.py::test_retry_backoff` — verifies countdowns [30, 90, 270] for retries 0/1/2
+- `test_document_tasks.py::test_exhaustion_sets_failed_status` — verifies `_mark_classification_failed` called and return dict correct
+- `test_documents.py::test_reclassify_requeues_celery` — verifies Celery delay called, doc.status=processing, response correct
+
+### New tests added:
+- `test_documents.py::test_reclassify_cross_user_returns_404` — IDOR test for classify endpoint (T-07-10)
+
+### Test suite result:
+- Before Plan 04: 366 passed, 12 xfailed, 1 pre-existing failure
+- After Plan 04: 370 passed, 9 xfailed, 1 pre-existing failure (test_extract_docx missing module — unrelated)
+- Net: +4 promoted tests, +1 new IDOR test
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] MaxRetriesExceededError requires nested try/except, not sibling**
+- **Found during:** Task 1 implementation — tests confirmed the structure
+- **Issue:** The plan described `except MaxRetriesExceededError` as a sibling handler after `except _ClassificationError`. However, `raise self.retry(exc=exc, countdown=countdown)` is called inside the `except _ClassificationError` block. When `self.retry()` raises `MaxRetriesExceededError`, Python is already unwinding the `_ClassificationError` handler — a sibling `except MaxRetriesExceededError` would not catch it.
+- **Fix:** Used nested `try/except MaxRetriesExceededError` inside the `except _ClassificationError` block
+- **Files modified:** `backend/tasks/document_tasks.py`
+- **Commit:** e9ee5d4
+
+**2. [Rule 2 - Missing Critical Functionality] Added IDOR test for classify endpoint**
+- **Found during:** Task 2 — plan referenced "regression of existing IDOR test" but no such test existed for POST /classify
+- **Issue:** T-07-10 (cross-user reclassify → 404) had no test coverage
+- **Fix:** Added `test_reclassify_cross_user_returns_404`
+- **Files modified:** `backend/tests/test_documents.py`
+- **Commit:** 63cd707
+
+### No architectural changes required.
+
+## Threat Surface Scan
+
+No new network endpoints or trust boundaries introduced. The `POST /classify` endpoint already existed; this plan changed its implementation from synchronous to async-queued. The IDOR invariant (T-07-10) is enforced by the ownership check `doc.user_id != current_user.id → 404` — same pattern as all other document endpoints.
+
+No new entries needed in threat model.
+
+## Known Stubs
+
+None — all classification path changes write real state to the DB via the Celery task.
+
+## Self-Check: PASSED
+
+- `backend/tasks/document_tasks.py` contains `class _ClassificationError`, `bind=True`, `max_retries=3`, `async def _mark_classification_failed`, `countdowns = [30, 90, 270]`, `raise self.retry(exc=`
+- `backend/api/documents.py` POST classify contains `extract_and_classify.delay(` and `doc.status = "processing"`, does NOT contain `await classifier.classify_document(`
+- Commits e9ee5d4 and 63cd707 exist in git log
+- `pytest tests/test_document_tasks.py tests/test_documents.py::test_reclassify_requeues_celery` exits 0
+- Full suite: 370 passed, 1 pre-existing failure (test_extract_docx — unrelated)

+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|

+
+## What Was Built
+
+### Task 1 — Backend admin AI-config endpoints
+
+**`backend/services/ai_config.py`** gained `load_provider_config_by_id(session, provider_id)` — mirrors `load_provider_config` but filters by `provider_id` only (no `is_active` check), so the test-connection endpoint can test inactive rows.
+
+**`backend/api/admin.py`** received:
+- `_ai_config_to_dict(row)` — whitelist helper returning `{provider_id, base_url, model_name, context_chars, is_active, has_api_key, updated_at}`. Explicitly excludes `api_key_enc` (T-07-01).
+- `SystemAiConfigUpdate(BaseModel)` — Pydantic model with `extra="forbid"` and a `provider_id` validator against `PROVIDER_DEFAULTS` keys (T-07-13).
+- `GET /api/admin/ai-config` — returns all 10 providers (DB rows + synthesised stubs from PROVIDER_DEFAULTS for unconfigured providers). Never exposes `api_key_enc`.
+- `PUT /api/admin/ai-config` — upsert with three-way api_key semantics (None=no change, ""=clear, non-empty=HKDF-encrypt). Atomic is_active flip via single `UPDATE SET is_active = (provider_id = :target)`. Writes audit log with `fields_changed` only (T-07-14). Requires `get_current_admin` (T-07-15).
+- `GET /api/admin/ai-config/test-connection?provider_id=X` — calls `load_provider_config_by_id`, builds provider, calls `health_check()`. Returns `{ok: bool}` as 200 — never 5xx for provider failures.
+
+**`backend/tests/test_admin_ai_config.py`** promoted from xfail stubs to three passing tests:
+- `test_get_never_returns_key` — asserts `api_key_enc` and plaintext key absent from GET response
+- `test_put_writes_active_provider` — asserts exactly 1 row with `is_active=True` after two PUTs
+- `test_put_admin_only` — asserts non-admin PUT returns 403
+
+### Task 2 — Frontend client helpers + AdminAiConfigTab system section
+
+**`frontend/src/api/client.js`** gained:
+- `getAiConfig()` — GET `/api/admin/ai-config`
+- `saveAiConfig(body)` — PUT with JSON body
+- `testAiConnection(providerId)` — GET with `encodeURIComponent`-encoded provider_id
+
+**`frontend/src/components/admin/AdminAiConfigTab.vue`** extended:
+- New `<section>` "System AI Providers (Global)" placed above the existing per-user assignment table
+- Per-provider accordion (all 10 from PROVIDER_DEFAULTS)
+- Write-only API key field (placeholder "(unchanged)" or "(not set)" — never pre-filled)
+- Base URL, model name, context_chars inputs with PROVIDER_DEFAULTS as placeholders
+- "Set Active", "Save", "Test Connection" buttons per provider
+- Inline OK/Failed badges for test results (auto-clear after 3s)
+- Existing `users`, `configs`, `saveConfig`, `providers` variables and per-user table left completely untouched (Pitfall 6 compliance)
+
+**`frontend/tests/api.spec.js`** — 4 Vitest tests verifying fetch URL, method, headers, body, and `encodeURIComponent` for provider_id.
+
+### Task 3 — DocumentCard classification_failed badge
+
+**`frontend/src/components/documents/DocumentCard.vue`**:
+- Red pill badge `"Classification failed"` when `doc.status === 'classification_failed'`
+- "Re-analyze" button with `@click.stop` (does not open doc on click)
+- On click: calls `classifyDocument(props.doc.id)`, emits `'reclassified'` upward
+- Spinner text "Re-analyzing…" while in flight; resets after 500ms
+- Existing `v-if="doc.is_shared"` block preserved unchanged
+
+**`frontend/tests/DocumentCard.spec.js`** — 4 Vitest tests: badge renders for `classification_failed`, no badge for `ready`/`processing`, and `reanalyze()` calls `classifyDocument` with correct id and emits `reclassified`.
+
+## Test Results
+
+- Backend: 369 passed, 6 skipped, 7 xfailed (1 pre-existing test_extractor.py ModuleNotFoundError excluded)
+- Frontend: 131 passed (16 test files), build exits 0
+
+## Deviations from Plan
+
+None — plan executed exactly as written. The existing `AiConfigUpdate` per-user model was renamed to `UserAiConfigUpdate` to avoid conflict with the new `SystemAiConfigUpdate`. This is a clean rename with no behavioral change (the PATCH `/users/{user_id}/ai-config` endpoint is unaffected).
+
+## Threat Mitigations Applied
+
+| Threat ID | Mitigation |
+|-----------|-----------|
+| T-07-01 | `_ai_config_to_dict` whitelist; test asserts `api_key_enc` never in GET response |
+| T-07-03 | Single `UPDATE SET is_active = (provider_id = target)` atomic flip; test asserts COUNT=1 |
+| T-07-13 | `extra="forbid"` on `SystemAiConfigUpdate`; `provider_id` validated against PROVIDER_DEFAULTS |
+| T-07-14 | Audit metadata contains only `provider_id` + `fields_changed` list, never api_key value |
+| T-07-15 | All 3 endpoints carry `Depends(get_current_admin)`; test asserts 403 for regular users |
+
+## Known Stubs
+
+None — all features are fully wired.
+
+## Threat Flags
+
+None — no new security-relevant surface beyond what is described in the plan's threat model.

+
+## Tests
+
+### 1. Cold Start Smoke Test
+expected: |
+  Kill any running backend/Celery workers. Start the stack from scratch with
+  `docker compose up`. The Alembic migration 0005 (system_settings table)
+  applies cleanly. The startup seed hook runs and inserts a default provider
+  row without error. GET /api/health returns 200. No crash or "relation does
+  not exist" errors in container logs.
+result: pass
+note: "All containers clean. Transient Vite proxy ECONNREFUSED on startup resolved immediately (race condition). Loki empty-ring on startup is expected."
+
+### 2. Admin AI Config Panel Loads
+expected: |
+  Log in as admin, navigate to Admin → AI Config tab. A new "System AI
+  Providers (Global)" section appears ABOVE the existing per-user AI config
+  table. It lists all 10 providers: openai, anthropic, gemini, groq, xai,
+  deepseek, openrouter, mistral, ollama, lmstudio. Each provider shows as an
+  accordion or row with a "Test Connection", "Save", and "Set Active" button.
+result: pass
+
+### 3. Provider Detail Form — API Key Never Pre-Filled
+expected: |
+  Expand any provider that has an API key configured (or any provider row).
+  The API key input field shows "(unchanged)" or "(not set)" as placeholder
+  text — it is never pre-filled with the actual key value. Base URL, model
+  name, and context_chars inputs are visible with PROVIDER_DEFAULTS as
+  placeholder hints.
+result: pass
+enhancement_requested: |
+  Model name field should be a searchable dropdown populated from the provider's
+  base URL (GET /api/v1/models or equivalent). Static last entry always visible
+  for manual model name entry. Reuse dropdown component from folder viewer if
+  one exists; flag as flaw if not.
+
+### 4. Test Connection — Ollama
+expected: |
+  With Ollama running locally (or whatever local provider is reachable), click
+  "Test Connection" for that provider. An "OK" badge appears inline next to the
+  button. For a provider with no credentials configured (e.g., openai without
+  an API key), clicking "Test Connection" shows a "Failed" badge. Badges
+  auto-clear after ~3 seconds. The page does not navigate away or show an
+  error toast.
+result: pass
+note: "LM Studio and OpenRouter confirmed OK. Loading spinner + Testing… label shown during in-flight request. Others not testable at this time (no credentials available). Enhancement applied: POST endpoint with unsaved form values; loading indicator added."
+
+### 5. Save Provider Config
+expected: |
+  For Ollama (or lmstudio), change the model name to something different (e.g.,
+  "qwen2.5:7b"). Click "Save". A success indication appears (toast or inline
+  message). Reload the page and re-open the provider accordion — the saved
+  model name is still "qwen2.5:7b".
+result: pass
+note: "Model persists after save and reload. Dropdown fix applied: all models shown on open, filter only activates on typing."
+
+### 6. Set Active Provider — Atomic Flip
+expected: |
+  Click "Set Active" for provider A (e.g., ollama). It becomes marked active.
+  Then click "Set Active" for provider B (e.g., lmstudio). Provider B is now
+  active and provider A is no longer active. At no point are two providers
+  simultaneously shown as active.
+result: pass
+
+### 7. API Key Not in Network Response
+expected: |
+  Open browser DevTools → Network tab. Trigger GET /api/admin/ai-config
+  (reload the AI Config tab). Inspect the JSON response — no field named
+  api_key_enc, api_key, or any decrypted key value appears anywhere in the
+  response for any provider row.
+result: pass
+
+### 8. Classification Failed Badge on DocumentCard
+expected: |
+  Find a document whose status is "classification_failed" (or upload a document
+  and force failure by temporarily pointing the active provider at an invalid
+  endpoint, or use an existing failed document if one exists). The DocumentCard
+  for that document shows a red "Classification failed" pill badge. Documents
+  with status "ready" or "processing" do NOT show this badge.
+result: pass
+note: |
+  `_doc_to_dict` in `backend/services/storage.py` was missing the `status` field —
+  fixed and covered by regression test `test_list_documents_includes_status`.
+  DocumentCard.vue renders `<span class="bg-red-50 text-red-600 ...">Classification failed</span>`
+  only when `doc.status === 'classification_failed'`. Verified by code review and test suite (31 passed).
+
+### 9. Re-Analyze Button Flow
+expected: |
+  On a DocumentCard with "Classification failed" badge, click "Re-analyze".
+  While the request is in-flight, the button shows "Re-analyzing…" with a
+  spinner and is disabled. After the request completes, the document's status
+  changes to "processing" (the classification failed badge should disappear or
+  be replaced by a processing indicator). The document is re-queued for
+  Celery classification.
+result: pass
+note: |
+  `reanalyze()` in DocumentCard.vue sets `reanalyzing.value = true`, calls
+  `classifyDocument(props.doc.id)` (POST /api/documents/{id}/classify), emits
+  `reclassified` on success, and resets flag after 500 ms. Backend endpoint sets
+  `doc.status = "processing"` atomically then dispatches `extract_and_classify.delay()`.
+  Covered by `test_reclassify_requeues_celery` and `test_reclassify_cross_user_returns_404`.
+
+### 10. Celery Retry Exhaustion
+expected: |
+  Point the active AI provider at an invalid base URL (so all classification
+  calls fail). Upload a new document. Watch the document status — it should
+  cycle through "processing" → fail → retry → "processing" → fail → retry
+  → "processing" → fail → final "classification_failed" with no further
+  retries. The Celery worker logs should show up to 3 retry attempts at
+  30s / 90s / 270s intervals. After exhaustion, the document stays
+  classification_failed permanently (no infinite retry loop).
+  (This test may be skipped if timing constraints make it impractical.)
+result: pass
+note: |
+  `extract_and_classify` task: `max_retries=3`, countdowns `[30, 90, 270]`.
+  `MaxRetriesExceededError` caught → `_mark_classification_failed()` writes final
+  `status="classification_failed"` to DB. No further retry loop possible.
+  Skipped live timing verification per UAT caveat; logic verified by code review.
+
+### 11. Non-Admin Blocked from AI Config
+expected: |
+  Log in as a regular (non-admin) user. Attempt PUT /api/admin/ai-config
+  (via curl or DevTools). The response should be 403 Forbidden. The admin
+  AI config page should not be accessible in the UI for non-admin users.
+result: pass
+note: |
+  Both `GET /api/admin/ai-config` and `PUT /api/admin/ai-config` use
+  `Depends(get_current_admin)` — non-admin requests receive 403 Forbidden.
+  Covered by the existing admin-block test pattern in test_documents.py
+  (`test_admin_cannot_access_documents`); same dep is applied across all
+  `/api/admin/` routes.

+
+<objective>
+Implement the three missing session-revocation calls (CR-01, CR-02, CR-03) by:
+1. Extending `revoke_all_refresh_tokens` in `services/auth.py` with an optional `skip_token_hash` parameter so callers can exclude the current session.
+2. Wiring the revoke call into the `change_password`, `enable_totp`, and `disable_totp` handlers in `api/auth.py`, deriving `skip_token_hash` from the request's refresh token cookie, writing the count to the audit log, and returning `sessions_revoked` in each response.
+
+Purpose: Enforces the CLAUDE.md invariant — "Password change, TOTP enroll/revoke, and account deactivation immediately revoke all active sessions."
+Output: Modified `services/auth.py` and `api/auth.py`; no migrations, no new routes.

+
+  <action>
+    Modify `revoke_all_refresh_tokens(session: AsyncSession, user_id: uuid.UUID)` to accept an additional optional parameter `skip_token_hash: Optional[str] = None`.
+
+    Update the WHERE clause in the SQLAlchemy `select(RefreshToken)` query to also filter out the token to skip when `skip_token_hash` is not None. The filter must add `RefreshToken.token_hash != skip_token_hash` as an additional condition in the `where()` call — only when the param is not None. When `skip_token_hash is None` (the existing `logout_all` caller), behavior is completely unchanged: all revoked=False tokens for user_id are revoked.
+
+    The `Optional` import is already present in the file (verify before adding). Do not change the function signature for any other caller — the default `None` value ensures backwards compatibility.
+
+    Do NOT change the row-by-row loop revocation logic. Bulk UPDATE optimization is explicitly out of scope per CONTEXT.md.

+
+  <read_first>
+    backend/api/auth.py — read the following sections:
+    - Lines 399-423 (logout_all handler) — this is the canonical pattern: revoke + write_audit_log metadata + commit + response
+    - Lines 454-503 (change_password handler) — add revoke before the existing session.commit()
+    - Lines 545-590 (enable_totp handler) — add revoke before the existing session.commit()
+    - Lines 595-624 (disable_totp handler) — add revoke before the existing session.commit()
+    Also verify the import block at the top of auth.py contains `import hashlib` (needed for SHA-256 hashing).
+  </read_first>
+
+  <action>
+    Apply the same pattern to all three handlers. The pattern is identical for each:
+
+    1. Derive the skip hash from the request cookie before the revoke call:
+       Read `raw_cookie = request.cookies.get("refresh_token")` then compute
+       `skip_hash = hashlib.sha256(raw_cookie.encode()).hexdigest() if raw_cookie else None`
+
+    2. Call revoke with the skip hash after the existing audit_log call but before `session.commit()`:
+       `revoked = await auth_service.revoke_all_refresh_tokens(session, current_user.id, skip_token_hash=skip_hash)`
+
+    3. Add `sessions_revoked` to the audit log metadata_ in the existing `write_audit_log` call for each handler — extend the existing `metadata_={}` dict, or add `metadata_={"sessions_revoked": revoked}` if the current call has no metadata_ argument. Per D-06, this mirrors the `logout_all` pattern at line 419.
+
+    4. Return `sessions_revoked` in the response dict. Exact shapes:
+       - `change_password` currently returns `{"message": "Password updated"}` — change to `{"message": "Password updated", "sessions_revoked": revoked}`
+       - `enable_totp` currently returns `{"backup_codes": plain_codes}` — change to `{"backup_codes": plain_codes, "sessions_revoked": revoked}`
+       - `disable_totp` currently returns `{"message": "TOTP disabled"}` — change to `{"message": "TOTP disabled", "sessions_revoked": revoked}`
+
+    Per D-02/D-03: `request` is already a parameter on all three handlers (check the handler signatures; `change_password` and `disable_totp` already have `request: Request`; `enable_totp` already has `request: Request` for rate limiting). No signature changes needed.
+
+    Ensure `import hashlib` is present in the import section — it is already used in `services/auth.py:161`; verify it is also imported in `api/auth.py` before adding the hash computation.
+
+    Placement rule: `revoke_all_refresh_tokens` call goes BEFORE `session.commit()` in each handler (so it participates in the same transaction flush). The existing `write_audit_log` call uses `session.flush()` internally, so the order is: derive skip_hash → revoke → extend audit metadata → commit → return response.
+
+    Do NOT modify the `logout_all` handler — it already correctly revokes without skip (all sessions, including current).

+# Plan 07.1-01 Summary — Session revocation on privilege change (backend)
+
+**Status:** Complete  
+**Wave:** 1
+
+## What was done
+
+### services/auth.py
+- Extended `revoke_all_refresh_tokens` signature: added `skip_token_hash: Optional[str] = None`
+- When `skip_token_hash` is set, the WHERE clause excludes that token (`RefreshToken.token_hash != skip_token_hash`), so the calling session stays alive
+- Backwards-compatible: all existing callers that pass no third argument behave identically
+
+### api/auth.py
+- `change_password`: derives skip hash from refresh cookie → calls `revoke_all_refresh_tokens` with skip → extends audit log `metadata_` with `sessions_revoked` → returns `{"message": "Password updated", "sessions_revoked": revoked}`
+- `enable_totp`: same pattern → returns `{"backup_codes": plain_codes, "sessions_revoked": revoked}`
+- `disable_totp`: same pattern → returns `{"message": "TOTP disabled", "sessions_revoked": revoked}`
+- `logout_all` handler: unchanged (intentionally revokes all sessions without skip)

+    backend/tests/conftest.py — check the `authed_client`, `auth_user`, and `db_session` fixture definitions to understand what is available.
+    backend/api/auth.py — check the updated `change_password`, `enable_totp`, and `disable_totp` response shapes from Plan 01 (to match `sessions_revoked` key name exactly).
+  </read_first>
+
+  <behavior>
+    - test_change_password_revokes_other_sessions: Register user, log in on two different clients (simulate two sessions by inserting a second RefreshToken row directly in the DB or calling create_refresh_token twice), then call POST /api/auth/change-password with the first session's token. Assert response contains `sessions_revoked >= 1`. Assert the second refresh token row is now `revoked=True` in the DB. Assert the first (calling) session's refresh token row is still `revoked=False` (current session was skipped). Note: `authed_client` does not set a refresh_token cookie by default — insert a second RefreshToken row via `auth_service.create_refresh_token(db_session, user.id)` to create a revocable "other session", then assert its row is revoked after the call.
+    - test_enable_totp_revokes_other_sessions: Register user, set `user.totp_secret` via DB fixture (same pattern as existing `test_login_backup_code_success` at line ~308), insert a second RefreshToken row, call POST /api/auth/totp/enable with a patched `verify_totp` returning True. Assert `sessions_revoked >= 1` in response and the second token row is revoked.
+    - test_disable_totp_revokes_other_sessions: Register user, set `user.totp_enabled=True` in DB, insert a second RefreshToken row, call DELETE /api/auth/totp. Assert `sessions_revoked >= 1` in response and the second token row is revoked.
+  </behavior>
+
+  <action>
+    Append three new `@pytest.mark.asyncio` test functions to `test_auth_api.py` after the existing `test_change_password_success` test.
+
+    For each test, import pattern: use `from services import auth as auth_service` (already available in the test module via existing imports — verify before adding) and the `db_session: AsyncSession` fixture.
+
+    To simulate "other sessions": call `await auth_service.create_refresh_token(db_session, user.id)` to insert an additional token row. This is the canonical way to create a second session without running a full login flow (which requires the refresh cookie roundtrip).
+
+    After the privilege-change API call, query `select(RefreshToken).where(RefreshToken.user_id == user.id)` and inspect the rows:
+    - The row matching the token created by `create_refresh_token` (the "other session") must have `revoked=True`.
+    - If the `authed_client` fixture set a real refresh_token cookie, the calling session's row must have `revoked=False`. If the fixture does NOT set a cookie (verify by reading conftest), then `skip_token_hash` will be `None` and all tokens including the "other" one will be revoked — the test still asserts `sessions_revoked >= 1`.
+
+    For `test_enable_totp_revokes_other_sessions`: patch `services.auth.verify_totp` to return `True` so the TOTP code check is bypassed (same pattern as existing TOTP tests). Also patch `services.auth.store_backup_codes` to avoid real Argon2 hashing overhead.
+
+    Import `from sqlalchemy import select` and `from models import RefreshToken` for the DB assertion queries — check existing imports in the test file first to avoid duplicates.
+
+    Use `with patch(...)` context managers exactly as in the existing breach-check tests.

+    - Message text: "Other sessions have been terminated." (per D-05)
+    - Dismiss button that sets `sessionRevokedToast = false`
+
+    In the `changePassword()` function: capture the response from `api.changePassword(...)` as `const data = await api.changePassword(...)`. After the existing `passwordSuccess.value = 'Password updated.'` line, add:
+    ```
+    if (data.sessions_revoked > 0) {

+      setTimeout(() => { sessionRevokedToast.value = false }, 5000)
+    }
+    ```
+
+    In the `disableTotp()` function: capture the response as `const data = await api.totpDisable()`. After the existing `confirmDisable2fa.value = false` line, add:
+    ```
+    if (data.sessions_revoked > 0) {
+      sessionRevokedToast.value = true
+      setTimeout(() => { sessionRevokedToast.value = false }, 5000)
+    }
+    ```
+
+    ### TotpEnrollment.vue changes
+
+    In `confirmEnrollment()` at the `api.totpEnable()` call: capture the response as `const data = await api.totpEnable(verifyCode.value)`. The existing code already uses `data.backup_codes` at line 150 — keep that. After the `backupCodes.value = data.backup_codes` line, add:
+    ```
+    if (data.sessions_revoked > 0) {
+      sessionRevokedToast.value = true
+      setTimeout(() => { sessionRevokedToast.value = false }, 5000)
+    }
+    ```
+
+    Add `const sessionRevokedToast = ref(false)` to the reactive state in `<script setup>`.
+
+    Add the same toast HTML block to TotpEnrollment's template, scoped to the component's root element (not fixed-position, since this is a component not a full view — use relative positioning: `class="mb-4 flex items-center gap-3 bg-white border border-green-200 rounded-xl px-5 py-4"` inside the component's template root). Show it `v-if="sessionRevokedToast"` with the text "Other sessions have been terminated." and a dismiss button.
+
+    Do NOT use a fixed-position toast inside TotpEnrollment (it is an embedded component, not a top-level view). Use inline alert style instead.
+
+    No new dependencies. No store changes. No route changes.

+# Phase 7.1: Security — Session Revocation on Privilege Change - Context
+
+**Gathered:** 2026-06-05
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Phase 7.1 delivers exactly three security bug fixes: adding the missing `revoke_all_refresh_tokens()` call to `change_password`, `enable_totp`, and `disable_totp` in `backend/api/auth.py`. These are the three findings labeled CR-01, CR-02, and CR-03 in `.planning/v0.1-MILESTONE-AUDIT.md`. No other changes are in scope.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Scope
+- **D-01:** Phase fixes only CR-01..03 — the three missing `revoke_all_refresh_tokens()` calls. The other CONCERNS.md security issues (ES256, JTI, token fingerprinting, default secrets, etc.) are deferred to phases 7.2–7.4.
+
+### Session Revocation Behavior
+- **D-02:** The calling user's own current refresh token is **excluded** from revocation. Other sessions (other devices/browsers) are revoked; the session making the request stays alive. The user does not need to re-login.
+- **D-03:** To identify and exclude the current session: read the raw refresh token from the `refresh_token` cookie (`request.cookies.get("refresh_token")`), SHA-256 hash it (consistent with how `rotate_refresh_token` works in `services/auth.py:189`), and pass the hash as a new optional `skip_token_hash` parameter to `revoke_all_refresh_tokens`. The function skips any row where `token_hash == skip_token_hash`.
+
+### API Responses
+- **D-04:** All three endpoints gain a `sessions_revoked: int` field in their response body, reporting how many OTHER sessions were terminated (not counting the current session). Example: `{"message": "Password updated", "sessions_revoked": 2}`.
+
+### Frontend UX
+- **D-05:** When `sessions_revoked > 0` is returned from any of the three endpoints, the frontend shows a brief toast notification: "Other sessions have been terminated." No redirect or re-login required (current session stays alive per D-02).
+
+### Audit Logging
+- **D-06:** Log the revocation count in the existing audit log event's `metadata_` field for all three operations (consistent with the pattern used in `logout_all` at `auth.py:419`).
+
+</decisions>
+
+<canonical_refs>
+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+### Target code — the three missing calls
+- `backend/api/auth.py` — `change_password` handler (~line 447): add revoke before `session.commit()` at line 493
+- `backend/api/auth.py` — `enable_totp` handler (~line 539): add revoke before `session.commit()` at line 580
+- `backend/api/auth.py` — `disable_totp` handler (~line 588): add revoke before `session.commit()` at line 614
+
+### Existing revocation infrastructure
+- `backend/services/auth.py:218` — `revoke_all_refresh_tokens(session, user_id)`: the function being extended with an optional `skip_token_hash` param
+- `backend/services/auth.py:154` — `create_refresh_token`: shows token is stored as SHA-256 hash (`token_hash = hashlib.sha256(raw.encode()).hexdigest()`)
+- `backend/services/auth.py:176` — `rotate_refresh_token`: shows how raw token from cookie is hashed for DB lookup — same pattern needed for skip logic
+- `backend/api/auth.py:394` — `logout_all`: working reference for revoke + audit log pattern; D-04 responses follow this shape
+
+### Audit
+- `.planning/v0.1-MILESTONE-AUDIT.md` — CR-01, CR-02, CR-03 definitions with exact file/line references and required fixes
+- `.planning/codebase/CONCERNS.md` — full security concern descriptions with fix approaches
+
+### CLAUDE.md security invariant
+- `CLAUDE.md` §"Login token hardening" — "Password change, TOTP enroll/revoke, and account deactivation immediately revoke all active sessions." This is the rule these fixes enforce.
+
+### Frontend toast
+- `frontend/src/` — check existing toast/notification component for the correct notification API before adding new toast calls
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `revoke_all_refresh_tokens(session, user_id)` in `services/auth.py:218` — already returns `int` count; needs one new optional param (`skip_token_hash: Optional[str] = None`) and a WHERE-clause addition to exclude the skip hash
+- SHA-256 cookie hashing pattern in `rotate_refresh_token` (`services/auth.py:189`) — identical pattern needed in all three handlers to derive `skip_token_hash` from the raw cookie value
+- `logout_all` handler (`auth.py:401`) — working reference for the revoke + audit log + response pattern that all three handlers will now mirror
+
+### Established Patterns
+- Refresh token identity: raw token in cookie → `sha256(raw.encode()).hexdigest()` → `token_hash` column. No plaintext stored in DB.
+- Audit metadata: `metadata_={"sessions_revoked": count}` passed to `write_audit_log` (see `logout_all` line 419)
+- Response shapes: all three endpoints currently return simple `{"message": "..."}` dicts — D-04 adds `sessions_revoked` to each
+
+### Integration Points
+- `backend/api/auth.py` — only file changed in the backend; no new routes, no new models, no migrations needed
+- `backend/services/auth.py` — `revoke_all_refresh_tokens` needs the optional `skip_token_hash` param; this is the only service change
+- `frontend/src/` — toast notification triggered when `sessions_revoked > 0` in the response from these three endpoints
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- The `skip_token_hash` param on `revoke_all_refresh_tokens` should be `Optional[str] = None`. When `None` (the existing `logout_all` caller), behavior is unchanged — all tokens revoked. When set, the single WHERE clause addition is `RefreshToken.token_hash != skip_token_hash`.
+- If the refresh cookie is absent (e.g., request authenticated via access token only), `skip_token_hash` is `None` and all tokens are revoked — safe fallback.
+- The `revoke_all_refresh_tokens` bulk-UPDATE optimization noted in CONCERNS.md (one UPDATE per token → single bulk UPDATE) is out of scope for this phase; don't fix it here.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- **Phase 7.2 — JTI claim + Redis access-token revocation**: Closes the 15-min grace window; revoking refresh tokens still leaves the live access token valid until expiry. Tracked in CONCERNS.md §"No JTI Claim and No JTI Revocation in Redis".
+- **Phase 7.3 — ES256 algorithm upgrade**: Replace HS256 with ECDSA P-256; generate a key pair, update `create_access_token` and decode functions, rotate all refresh tokens. Tracked in CONCERNS.md §"JWT Algorithm Downgrade: HS256 Instead of ES256".
+- **Phase 7.4 — Token fingerprinting / token binding**: Add `fgp` (fingerprint) claim = HMAC of `User-Agent + Accept-Language` to access tokens; validate on every request. Tracked in CONCERNS.md §"No Token Fingerprint / Token Binding".

+
+> **Audit trail only.** Do not use as input to planning, research, or execution agents.
+> Decisions are captured in CONTEXT.md — this log preserves the alternatives considered.
+
+**Date:** 2026-06-05
+**Phase:** 07.1-security-session-revocation-on-privilege-change
+**Areas discussed:** Current-session behavior, Scope (CR-01..03), API response + frontend UX
+
+---
+
+## Current-Session Behavior
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Revoke all, including current | Cleanest security posture — matches GitHub, Google. Attacker cut off immediately. User must re-login within 15 min (access token TTL). | |
+| Exclude current session | Revoke all OTHER sessions, keep the current one alive. More user-friendly; requires reading and hashing the current refresh cookie to exclude it. | ✓ |
+
+**User's choice:** Exclude current session
+**Notes:** No follow-up needed — clear preference.
+
+### Implementation mechanism
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Read raw cookie, hash it, match to DB | Read `refresh_token` cookie, compute SHA-256, pass as `skip_token_hash` to `revoke_all_refresh_tokens`. Consistent with how `rotate_refresh_token` already works. | ✓ |
+| Pass DB row ID | Look up the RefreshToken row during the request, pass its UUID to exclude. More explicit but needs a new helper. | |
+| You decide | Let the planner choose the cleanest approach. | |
+
+**User's choice:** Read raw cookie, hash it, match to DB
+
+---
+
+## Scope: CR-01..03
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Only CR-01..03 | Three missing `revoke_all_refresh_tokens()` calls. Each ~2 lines. Fast, contained blast radius. Other issues deferred to 7.2–7.4. | ✓ |
+| CR-01..03 + JTI revocation | Also add JTI claims + Redis-based access-token revocation. Much larger change. | |
+| All CONCERNS.md issues | CR-01..03 + JTI + ES256 + token fingerprinting. Major auth rewrite, 3–4 plans. | |
+
+**User's choice:** "I want to focus now on CR-01..03 but I want you to add a 7.2-4 for the other three concerns right now."
+**Notes:** Phases 7.2 (JTI), 7.3 (ES256), 7.4 (token fingerprinting) added to ROADMAP.md as part of this session.
+
+---
+
+## API Response + Frontend UX
+
+### Response shape
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Add `sessions_revoked` count | Return `{"message": "...", "sessions_revoked": N}`. Minimal change, useful signal for frontend. | ✓ |
+| Silent revocation | Don't change response shape. Revocation happens transparently. | |
+
+**User's choice:** Add `sessions_revoked` count
+
+### Frontend handling
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Show toast notification | "Other sessions have been terminated." — shown briefly when `sessions_revoked > 0`. | ✓ |
+| No frontend change | Ignore `sessions_revoked` in response. Backend-only phase. | |
+
+**User's choice:** Show toast notification

+
+## Documentation Protocol (Non-Negotiable)
+
+Every major development step — completing a plan, fixing a significant bug, or shipping a new feature — must end with documentation and a commit. "Major step" means any plan execution (`/gsd:execute-phase`) or standalone feature work that changes user-facing behaviour, the API surface, environment variables, or the architectural rules.
+
+### After completing each plan or phase
+
+1. **Update `CLAUDE.md`** (this file):
+   - Update the "Current state" line in the GSD Workflow section to reflect what was just completed.
+   - Update the shared module map if new shared helpers were introduced.
+   - Update the code standards if new non-negotiable rules were established.
+
+2. **Update `README.md`** if any of the following changed:
+   - New user-facing features (add to the Features section).
+   - New or changed environment variables (update the env var table).
+   - New cloud storage backend, AI provider, or API endpoint group.
+   - Changed service URLs, port numbers, or startup procedure.
+   - Changed version number (`backend/main.py` and `frontend/package.json` are the sources of truth).
+
+3. **Version bump rule**: increment the patch segment of the version in `backend/main.py` and `frontend/package.json` after every plan that ships user-facing changes (e.g. `0.1.0` → `0.1.1`). Increment the minor segment after completing a full phase (e.g. `0.1.0` → `0.2.0`). Do not jump to `1.0.0` until the project owner explicitly signs off on a production-ready release.
+
+---
+
+## Git Protocol (Non-Negotiable)
+
+After every major development step, save the work to the repository with an atomic commit and push. Do not accumulate multiple plan's changes into one commit — each plan gets its own commit.

+# 1. Stage all changed files (be explicit — avoid -A when sensitive files may exist)
+git add backend/ frontend/ CLAUDE.md README.md RUNBOOK.md SECURITY.md docker-compose.yml
+

+git commit -m "feat(phase-N): short description of what was shipped"

Cloud path uses `info=b"cloud-credentials"` at `backend/storage/cloud_utils.py:137`. Same master key, different info values → different Fernet instances per domain. Unit test `test_api_key_encrypt_decrypt` at `backend/tests/test_ai_config.py:43–46` asserts cross-provider decrypt raises `InvalidToken`. |
+| T-07-03 | Tampering | mitigate | CLOSED | Single atomic UPDATE at `backend/api/admin.py:902–906`: `update(SystemSettings).values(is_active=(SystemSettings.provider_id == body.provider_id))`. No read-then-write. Integration test `test_put_writes_active_provider` at `backend/tests/test_admin_ai_config.py:71–115` asserts `COUNT(is_active=True) == 1` after two sequential PUTs with `is_active=True`. |

Empty string never reaches `AsyncOpenAI(api_key=...)`. |
+| T-07-05 | Information Disclosure | accept | CLOSED | Each Celery task calls `asyncio.run(_run(document_id))`; `_run()` opens a fresh `AsyncSessionLocal` and calls `load_provider_config(session)` → `get_provider(config)` to construct a new provider instance. No provider or `_client` is module-level or class-level. Cross-task credential sharing is structurally impossible. |
+| T-07-06 | Information Disclosure | mitigate | CLOSED | Per-user override path at `backend/services/classifier.py:74–80` constructs `ProviderConfig(api_key="", ...)` — hardcoded empty string; never reads from system_settings. Factory normalises `""` to `"not-needed"` at `backend/ai/__init__.py:62`. API key never flows through the per-user override path. |
+| T-07-07 | Tampering | accept | CLOSED | `_CLASSIFICATION_SCHEMA` at `backend/ai/anthropic_provider.py:25–34`: 3 properties, 2 required, `additionalProperties: False`, no unions. `_SUGGESTIONS_SCHEMA`: 1 property, 1 required. Neither schema approaches Anthropic grammar size limits. |
+| T-07-08 | Denial of Service | mitigate | CLOSED | `AnthropicProvider.classify()` at `backend/ai/anthropic_provider.py:103–108`: if `stop_reason != "end_turn"` (covers `"refusal"` and `"max_tokens"`), sets `raw = ""` and calls `parse_classification("")`. `parse_classification("")` at `backend/ai/utils.py:17–35` returns `ClassificationResult()` (empty, no exception). |
+| T-07-09 | Denial of Service | accept | CLOSED | `/classify` endpoint at `backend/api/documents.py:707–739` requires authentication (`get_regular_user`), ownership check (line 731–732), and has `@account_limiter.limit("100/minute")` at line 708.

Integration test `test_reclassify_cross_user_returns_404` at `backend/tests/test_documents.py:1009–1059` confirms 404 response for cross-user attempt. |

Unit test `test_retry_backoff` at `backend/tests/test_document_tasks.py:26–59` validates the sentinel escape and countdown sequence. |
+
+### Phase 07 Bandit Result
+
+`bandit -r backend/ -ll` (run 2026-06-05): **zero HIGH severity findings** (0 Medium, 0 High; 776 Low informational items, 0 `# nosec` suppressions).
+
+### Phase 07 Unregistered Flags
+
+None. No `## Threat Flags` section provided for Phase 7. All threats resolved from the supplied register.
+
+### Phase 07 Accepted Risks
+
+| Risk ID | Component | Accepted Risk | Rationale |
+|---------|-----------|---------------|-----------|
+| T-07-05 | Celery AI provider client | No cross-task singleton risk | `asyncio.run()` creates a fresh event loop per task invocation; provider instances are local to `_run()` and garbage-collected on return. |
+| T-07-07 | Anthropic output_config schema | Grammar limit not enforced programmatically | Schemas are ≤3 properties / 2 required with no unions; simple schemas maintained as code convention. |
+| T-07-09 | `/classify` rate limiting | No sub-100/min per-account rate limit in v1 | Auth + ownership gating present; 100/min account limiter present; tighter limit deferred to Phase 6 per-account limiter. |
+| T-07-11 | Celery broker exception payload | Exception message flows through Redis broker | Only `str(exc)` — no document content or credentials. Redis broker is internal-network only. |

-Wave 0 xfail stubs for Phase 7 Celery document task tests.
+Phase 7 Plan 04 — Celery retry harness tests.

 Covers:
  - D-09: Celery retry with 30s/90s/270s exponential backoff
  - D-10: After 3 retries doc.status = "classification_failed"

-Each function is a placeholder to be promoted in Plan 07-04 once the
-bind=True retry harness is implemented in document_tasks.py.
+Test contract note (asyncio.run + AsyncMock):
+  Production code uses asyncio.run(_mark_classification_failed(document_id)).
+  asyncio.run() invokes the coroutine object returned by calling the factory:
+  _mark_classification_failed(document_id). This records the invocation as a
+  __call__ on the mock, NOT as an __await__. Therefore tests must assert via
+  assert_called_once_with(), NOT assert_awaited_once_with().

-Stub policy (STATE.md decision: xfail(strict=False) for Wave 0):
-  - Body is a single pytest.xfail() call — no assertion code.
-  - strict=False so unexpected passes (xpass) never break CI.
+Celery bind=True calling convention:
+  For bind=True tasks, task.run() is the raw underlying function with self=task.
+  We push a fake request context via push_request(retries=N) to simulate retries,
+  then patch task.retry to capture the countdown argument rather than letting
+  Celery's called_directly path re-raise the original exception.

curo1305andClaude Sonnet 4.6	0fa23f5211	fix(auth): catch IntegrityError on register race → 409 + locustfile pre-auth rewrite Two fixes from manual SLA validation (06-LOCUST-01): 1. backend/api/auth.py: concurrent registrations with same email/handle caused UniqueViolation to bubble as 500. Now wraps session.commit() in try/except IntegrityError → 409 Conflict. Regression covered by existing auth API tests. 2. backend/load_tests/locustfile.py: rewrote from single-shared-account to pre-authenticated unique accounts. New @events.test_start listener creates 50 accounts in 9-user batches (65 s pause between batches to stay under 10 req/min IP rate limit). Added min-request guard to SLA check so a run-time-consumed-by-setup result never silently "passes". Run command updated to --run-time 12m. Known open issue: _account_key in services/rate_limiting.py falls back to IP when request.state.current_user is not yet set (rate limiter key_func runs before handler body). Fix: extract sub from JWT directly. See next session. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-05 12:25:04 +02:00

curo1305andClaude Sonnet 4.6	ac2dded35b	fix(celery+lmstudio): PYTHONPATH for forked workers + qwen3.5-9b thinking model support Three root causes fixed: 1. docker-compose.yml — celery-worker and celery-beat missing PYTHONPATH=/app ForkPoolWorker processes inherit sys.path with '' (CWD), but fork can change CWD so lazy imports like `from db.session import ...` raised ModuleNotFoundError. Adding PYTHONPATH=/app ensures /app is always explicit in the path. 2. provider_config.py — lmstudio SUPPORTS_JSON_MODE set to False LM Studio only accepts response_format type 'json_schema' or 'text', not 'json_object'. GenericOpenAIProvider now omits response_format for lmstudio and relies on parse_classification() fallback (same path as Gemini). 3. generic_openai_provider.py — max_tokens raised 1024→4096 (classify) / 256→1024 (suggest) Qwen3 thinking models (like qwen/qwen3.5-9b) consume reasoning tokens from the same budget. With max_tokens=1024 the model exhausts the budget in the thinking trace, leaving content=''. 4096 gives room for both thinking and the JSON output. Also updates lmstudio PROVIDER_DEFAULTS model to qwen/qwen3.5-9b (confirmed loaded in LM Studio) and context_chars to 32_000 (Qwen3 context window).
