+INSERT INTO ticket_history (ticket_record_id, field, old_value, new_value, changed_by, changed_at, created_at, updated_at, deleted_at, hash, canonical_version) VALUES ('06FY6QDAA8EWH7D2KKQF3TBHXR', 'description', NULL, 'Dockerfile runs `uvicorn ... --workers 2`, and `startup_event` in src/main.py creates a
+WikiChangeListener per worker. Each opens its own PostgreSQL LISTEN connection on
+`wiki_page_changes`, and Postgres delivers NOTIFY to *every* listening session — so both
+workers process the same event.
+
+Proven against production v1.9.1 on 2026-08-08:
+- pg_stat_activity shows two library_desk_listener sessions, both LISTEN "wiki_page_changes"
+- "Wiki.js change listener started successfully" is logged twice at startup
+- a single pg_notify(''wiki_page_changes'', ''claude-probe-no-colons'') produced exactly two
+  "Invalid notification payload" lines, one per worker (that payload is rejected before any
+  ingestion runs, so it is a side-effect-free probe)
+
+The debounce in wiki_change_listener.py (self._recent_notifications) is an in-process dict
+and cannot dedupe across workers. No Redis lock or other cross-process guard exists in the
+process_wiki_page_change path in src/routers/webhooks.py.
+
+IMPACT: each edit runs ingestion twice — duplicate embedding generation against Ollama plus
+duplicate Qdrant and Neo4j writes. On tower-of-joy, Ollama shares the GPU with
+Speaches/Whisper, so the wasted work has a cost beyond CPU.
+
+NOT YET ESTABLISHED: whether this is merely wasteful or actually corrupting. Check whether
+repeated ingestion of the same page creates duplicate Neo4j entities/relationships or
+duplicate Qdrant points — that changes the severity.
+
+OPTIONS TO WEIGH:
+- run the listener in one place only (single-worker sidecar, or elect an owner) so the
+  subscription is singular by construction
+- keep per-worker listeners and add a short-TTL Redis claim lock keyed on page_id, so only
+  the first worker to claim a notification processes it. Redis is already a dependency —
+  the job manager uses it.
+
+Whatever approach is taken must preserve the reconnect supervision added in v1.9.1 and its
+tests in tests/test_wiki_change_listener.py.

+WikiChangeListener per worker. Each opens its own PostgreSQL LISTEN connection on
+`wiki_page_changes`, and Postgres delivers NOTIFY to *every* listening session — so both
+workers process the same event.
+
+Proven against production v1.9.1 on 2026-08-08:
+- pg_stat_activity shows two library_desk_listener sessions, both LISTEN "wiki_page_changes"
+- "Wiki.js change listener started successfully" is logged twice at startup
+- a single pg_notify(''wiki_page_changes'', ''claude-probe-no-colons'') produced exactly two
+  "Invalid notification payload" lines, one per worker (that payload is rejected before any
+  ingestion runs, so it is a side-effect-free probe)
+
+The debounce in wiki_change_listener.py (self._recent_notifications) is an in-process dict
+and cannot dedupe across workers. No Redis lock or other cross-process guard exists in the
+process_wiki_page_change path in src/routers/webhooks.py.
+
+IMPACT: each edit runs ingestion twice — duplicate embedding generation against Ollama plus
+duplicate Qdrant and Neo4j writes. On tower-of-joy, Ollama shares the GPU with
+Speaches/Whisper, so the wasted work has a cost beyond CPU.
+
+NOT YET ESTABLISHED: whether this is merely wasteful or actually corrupting. Check whether
+repeated ingestion of the same page creates duplicate Neo4j entities/relationships or
+duplicate Qdrant points — that changes the severity.
+
+OPTIONS TO WEIGH:
+- run the listener in one place only (single-worker sidecar, or elect an owner) so the
+  subscription is singular by construction
+- keep per-worker listeners and add a short-TTL Redis claim lock keyed on page_id, so only
+  the first worker to claim a notification processes it. Redis is already a dependency —
+  the job manager uses it.
+
+Whatever approach is taken must preserve the reconnect supervision added in v1.9.1 and its
+tests in tests/test_wiki_change_listener.py.

-> **Start every session by reading this file.**
-> This file outlines the operational protocols, coding standards, and architectural decisions for this FastAPI project.
-
-## 1. Agent Operational Protocols
-
-### 🧠 Work Patterns (Plan-Act-Reflect)
-* **Plan:** Before writing code, briefly outline your plan. Identify which files you will touch and what the side effects might be.
-* **Act:** Execute the changes in small, atomic steps.
-* **Reflect:** After coding, verify your work. Did you break existing tests? Did you add new tests?
-
-### 🛡️ Git Discipline
-* **NEVER commit to `main` or `master` directly.** Always create a feature branch: `feature/your-feature-name` or `fix/issue-description`.
-* **Commit Messages:** Use the [Conventional Commits](https://www.conventionalcommits.org/) format.
-    * `feat: add user login endpoint`
-    * `fix: resolve database connection timeout`
-    * `refactor: split monolith dependency file`
-* **Atomic Commits:** Keep commits small. One logical change = one commit.
-
-### 📝 Changelog Maintenance
-* **Update `CHANGELOG.md`** with every user-facing change.
-* Format: `## [Unreleased] - YYYY-MM-DD` followed by `### Added`, `### Changed`, or `### Fixed`.
-
-### 🚀 Release Flow
-When changes are ready for deployment:
-
-1. **Ask user if deploy cycle is desired **
-
-2. **Update version** in `pyproject.toml`:
-   - Bug fixes: bump patch version (1.8.3 → 1.8.4)
-   - New features: bump minor version (1.8.4 → 1.9.0)
-
-3. **Update CHANGELOG.md**:
-   - Move items from `[Unreleased]` to new version section
-   - Add release date: `## [1.8.4] - 2025-12-16`
-
-4. **Commit and tag**:
-   ```bash
-   git add -A
-   git commit -m "fix: description of changes"
-   git tag v1.8.4
-   git push origin main --tags
-   ```
-
-5. **CI/CD triggers automatically**:
-   - Gitea CI builds Docker image on new tag
-   - Watchtower pulls and deploys to production
-   - Verify deployment: `curl http://192.168.86.149:8000/health`
-
----
-
-### 🧪 Local Development Setup
-* **Always test locally first** before committing and deploying. The build-deploy loop is slow.
-* **Start the local server** with `./wakeup.sh` - logs are written to `logs/server.log` for easy tailing
-* **Auto-reload**: The wakeup script runs uvicorn in reload mode - code changes are picked up automatically without restart (except for requirements.txt changes)
-* **Test REST endpoints** against `http://localhost:8778` using curl or similar tools
-* **Only deploy** when a phase or feature is complete and tested locally
-* **Environment**: Copy `.env.example` to `.env` and configure for your local setup (Ollama, Redis, Neo4j, Qdrant, Wiki.js hosts)
-* **Running tests**: Always use the venv explicitly to avoid environment mismatches:
-  ```bash
-  .venv/bin/python -m pytest tests/           # All tests
-  .venv/bin/python -m pytest tests/ -v        # Verbose output
-  ```

-## 2. FastAPI Architecture & Best Practices
-*Reference: [FastAPI Best Practices](https://github.com/zhanymkanov/fastapi-best-practices)*
-
-### 📂 Project Structure (Directory-based, NOT File-type based)
-Do **not** group files by type (e.g., one huge `routers` folder). Group by **domain/module** inside a `src/` directory.

+## [Unreleased]
+
+## [1.9.2] - 2026-08-16
+
+### Fixed
+
+- `/health` no longer reports the whole service unhealthy because one
+  dependency is merely slow. Its five probes (neo4j, qdrant, wikijs, searxng,
+  ollama) previously ran one after another with no timeout on neo4j or
+  qdrant, so a single hung dependency could block the response past the
+  container healthcheck's 10s timeout and get the container marked
+  unhealthy for a reason unrelated to its own liveness. Each probe is now
+  bounded at 2s and all five run concurrently, so one hanging dependency is
+  reported unhealthy on its own without holding up the others or the
+  response.
+- Internal-only: the three probes `check_service_health()` also computes
+  (paperless, system_settings, scheduler) received the same bounding and
+  concurrency, for consistency and because they carried the identical
+  unbounded-hang risk internally. This has no visible effect today — none
+  of the three is currently returned by `/health` — but protects a future
+  caller that does read them.
+
+## [1.9.1] - 2026-08-08
+
+### Fixed
+
+- The Wiki.js change listener now survives a database restart. It held a single
+  `LISTEN` connection with no supervision, so when the connection dropped it was
+  gone permanently while `running` stayed `True` — the service kept reporting
+  healthy and silently stopped indexing every page edit until someone restarted
+  the container. This happened for real on 2026-08-08 when `postgres-shared` was
+  redeployed. It now detects the drop via asyncpg's termination callback and
+  reconnects with bounded exponential backoff (1s doubling to a 60s cap),
+  retrying indefinitely because a database in maintenance does come back and
+  giving up would recreate the same silent deafness.
+- `WikiChangeListener.running` is derived from the live connection instead of
+  being assigned once at startup, so it can no longer claim a subscription that
+  does not exist.
+
+### Added
+
+- `/health` reports the change listener under `services.wiki_listener`
+  (`subscribed`, `reconnects`, `last_gap_seconds`). Nothing previously exposed
+  its state anywhere, which is why a dead listener went unnoticed. It is
+  deliberately excluded from the overall healthy/degraded verdict: it recovers on
+  its own, and flipping the container unhealthy for the duration of a database
+  outage would add a restart loop to an incident rather than information.
+- On reconnect the listener logs the outage duration and warns that `NOTIFY`
+  events emitted during the gap were lost and cannot be replayed, pointing at
+  `POST /maintenance/integrity-check` to reconcile. A reconciliation pass is not
+  performed automatically — tenant attribution for a changed page is non-trivial
+  here, and guessing it wrong writes content into the wrong user's namespace.
+
+## [1.9.0] - 2026-07-20
+
+### Security
+
+- The Wiki.js integration buttons no longer embed an API key in the browser. The re-index and entity-link endpoints now authenticate via the NPM `/library-desk/` proxy (Authentik session for external users, LAN bypass for internal), verified by a trusted proxy marker header. The previously-embedded key was a full-privilege key served to every wiki visitor; it has been rotated out of service.
+- `verify_api_key` now uses a constant-time comparison.
+
+### Changed
+
+- `static/wikijs-integration.js` calls library-desk same-origin (`/library-desk/...`) with `credentials: same-origin` and no `Authorization` header. Update the Wiki.js code-injection snippet to `<script src="/library-desk/static/wikijs-integration.js">`.
+- Machine callers (the Scheduler) continue to use the Bearer API key against the container-network endpoints; only the two browser endpoints switched to proxy auth.
+
+## [1.8.1] - 2026-07-19
+
+### Changed
+
+- Container images are now pushed via the `git.schweitz.net` registry endpoint (the `.internal` registry domain is being retired); no change to the image name consumed by Watchtower.
+- `.env.example` service URL defaults now use docker-dataplane container names (`wiki:3000`, `neo4j:7687`, `searxng:8080`, `paperless:8000`, `ollama:11434`) instead of host IP + published port, ahead of the Phase 4 port lockdown; AGENTS.md deploy health-check URL corrected from port 8000 to 8089.
+
+## [1.8.0] - 2026-07-14
+
+### Added
+
+- **Stub endpoints implemented** (`/ingest/check-updates`, `/ingest/status/{job_id}`, `/ingest/repo-status/{repository}`, `/deduplicate/check`) — all previously returned canned "not yet implemented" responses; all now require an explicit `user` (Phase B rule):
+  - `/ingest/check-updates` compares the `content_hash` now recorded on the tenant's Neo4j Document nodes at ingestion time against the SHA-256 of current Wiki.js page content in a single UNWIND Cypher query, returning `changed` / `new` / `deleted` page lists (auto-generated entity stubs excluded; documents whose stored hash predates hash tracking are flagged `stored_hash_missing` and count as changed).
+  - `/ingest/status/{job_id}` is backed by the Redis `JobManager` (jobs are tenant-scoped; other tenants' jobs return 404). `/ingest/page`, `/ingest/batch` and `/ingest/all` now record job entries and return a `job_id`.
+  - `/ingest/repo-status/{repository}` reports wiki page count vs indexed Document-node count under `users/{tenant}/{repository}` plus the tenant's Redis job statistics.
+  - `/deduplicate/check` runs a tenant-scoped Qdrant similarity scan: wiki chunk pairs above the threshold (default 0.9 cosine) grouped per page pair with best score, matching chunk-pair count, and page references. Read-only.
+- **Job + Scheduler task plumbing** — In-process hourly `job_cleanup_loop` (started at app startup, cancelled at shutdown) reclaims expired Redis job-set memberships (`JobManager.cleanup_expired_jobs`). `docs/scheduler-tasks.md` defines the four production Scheduler task payloads for the deploy checklist (nightly integrity 04:30, weekly quality report Sunday 03:00, daily Paperless orphan-cleanup 05:00 on the existing endpoint, and disabling `test_example_task`) with exact HTTP bodies (explicit `user=jpmschweitzer`, `${LIBRARY_API_KEY}` auth placeholder). `scripts/register_scheduler_tasks.py` reads the Scheduler API location from `SCHEDULER_URL` and registers them — dry-run by default (prints payloads), `--execute` gated and requiring `LIBRARY_API_KEY`.
+- **Weekly quality report** — `POST /maintenance/quality-report {user}` runs the duplicate scan, flags stale pages (not updated in N days AND ≤ M SearchQuery hits from the graph data), lists pages missing tags/description, folds in the latest integrity-check results (Redis-cached or run inline), and writes a dated report page to `users/{user}/system/quality-reports/YYYY-MM-DD` (same-day reruns update the same page — the page id is remembered in Redis because the Wiki.js listing lags page creation). Response returns the full report content + page path. Verified end-to-end against the local dev server as `llm_tester`.
+- **Nightly integrity check** — `POST /maintenance/integrity-check {user}` (read-only: reports, never auto-fixes) reports per tenant: wiki pages with ZERO vectors in Qdrant (silent-skip reindex victims), orphaned vectors whose wiki page no longer exists, unexpected Qdrant collections (test-tenant residue and unknown namespaces flagged; other services' collections counted as foreign), Neo4j Document nodes without wiki counterparts, plus counts and duration. The latest report is cached in Redis (30 days) so the weekly quality report can fold it in.
+
+### Fixed (Phase D review batch)
+
+- **Runtime prefetch registration is executable** - `SchedulerClient.register_volatile_fetch` (used by consolidation's `_register_prefetch`) registered tasks that were dead on arrival three ways: the JSON body sat under the ignored `body` key (`rest_api_executor` only reads `config["payload"]`), there was no `auth` block (the scheduled POST would 401 against library-desk's `verify_api_key`), and `user` was in the body while every `/volatile/fetch` endpoint requires it as a QUERY parameter (would 422). The config now puts `user` in the URL query string (URL-encoded), an empty `payload`, and `auth: {type: bearer, token: "${LIBRARY_API_KEY}"}` (substituted from the Scheduler's environment; never stored raw). `SchedulerClient` itself also sent no Authorization to the Scheduler API, so registration failed silently at consolidation time — it now sends `Authorization: Bearer <SCHEDULER_API_KEY>` (new `scheduler_api_key` setting; a client without a key logs a warning).
+- **Document sync uses delete-last reindex order** - `DocumentSyncService._index_vectors` deleted the document's existing chunks (`delete_by_filter`) BEFORE embedding, so a failed embedding pass (e.g. Ollama down) left the Paperless document with zero vectors until the next successful sync — the exact hazard already fixed for wiki pages in `VectorService.update_from_page`. Chunk point ids are now deterministic (uuid5 of `document_{id}_chunk_{i}`, replacing random uuid4) so re-upserting overwrites in place; new points are upserted first and stale points (including legacy uuid4 ones) are pruned afterwards, only after a successful upsert.
+- **5MB response cap now aborts the download** - `ContentExtractor._fetch` buffered the entire response body in memory before truncating to `MAX_RESPONSE_BYTES`, so the cap protected Trafilatura but not memory/bandwidth (a multi-hundred-MB URL was still fully downloaded, on up to `max_urls_per_batch` concurrent fetches). Fetches are now streamed (`client.stream` + `aiter_bytes`) and the connection is closed as soon as the cap is reached.
+- **Registrar authenticates to the Scheduler API** - `scripts/register_scheduler_tasks.py --execute` sent no `Authorization` header while the Scheduler's task-management endpoints are Bearer-guarded (`verify_api_key`: 401 on missing key), so the existence probes 401'd (misread as "task absent") and every registration failed; only the public `/health` gate passed. `--execute` now requires `SCHEDULER_API_KEY` in the environment (refuses to run without it, key is never stored) and sends `Authorization: Bearer $SCHEDULER_API_KEY` on all of its own HTTP calls. Deploy note updated alongside the existing `LIBRARY_API_KEY` requirement.
+
+### Fixed (hazards batch)
+
+- **CORS wildcard + credentials removed** - `allow_origins=["*"]` combined with `allow_credentials=True` told browsers to attach credentials for any site. Credentials are now disabled (all real callers are server-to-server and use the `Authorization` header, which wildcard-origin CORS without credentials still permits) and the origin list is configurable via `CORS_ALLOW_ORIGINS` (comma-separated, default `*`).
+- **Scheduler task auth no longer stores raw tokens** - the Phase C Scheduler task definitions put `Authorization: Bearer ${LIBRARY_API_KEY}` in plain `headers` and the registrar substituted the REAL key client-side on `--execute`, which would persist it in the Scheduler's `scheduled_tasks.config` JSONB column — and the Scheduler's `rest_api_executor` does not substitute env vars in plain headers anyway (only in `url`/`payload`/`auth`). The definitions now use the executor's `auth: {type: bearer, token: "${LIBRARY_API_KEY}"}` block, substituted from the SCHEDULER's environment at execution time; the registrar sends the placeholder verbatim and no longer needs (or accepts) the key. Also fixed: the JSON body moved from the ignored `body` key to `payload` (the executor only reads `config["payload"]`, so the tasks would have POSTed empty bodies and failed Phase B user validation).
+- **Reranker index parser dedupes** - an LLM ranking answer like `3,3,1` inserted the same result into the final ranking twice; parsed indices are now deduplicated preserving first occurrence.
+- **Single HybridRAG wiring point** - three separate constructions existed: an unused `dependencies.get_hybrid_rag_service` singleton lacking `volatile_service`, an inline per-request copy in the `/query/hybrid` router, and another inline copy in `/wiki/pages/smart-create` also lacking `volatile_service`. All callers now use the dependencies singleton, which includes `volatile_service` (smart-create research can now hit the volatile cache leg).
+- **Hot-path Neo4j writes use write transactions** - remaining graph writes ran as auto-commit `execute_query` calls (no retry, no transaction-function semantics): `GraphService` ingestion (`update_from_page` document + entity queries), `delete_page`, `create_entity_mentions`, document/paperless/collection node deletion, orphan-entity purge, stale-document purge, `cleanup_broken_relationships`; the webhook rename/delete cleanup writes; document-sync `_index_graph`; and consolidation's `_mark_search_processed`/`_add_entity_to_graph`. All now go through `execute_write` (managed transaction with driver retry). Read paths are unchanged.
+
+### Changed (performance)
+
+- **Content extractor hardened** - `ContentExtractor` now downloads pages with `httpx.AsyncClient` under real connect (3s) and read timeouts on the event loop; only the CPU-bound Trafilatura parse runs in the thread pool. Previously `trafilatura.fetch_url` ran inside the worker thread with no caller-side timeout control, so an `asyncio.wait_for` timeout abandoned the thread while it kept downloading for up to ~30s. Trafilatura now parses each document ONCE via `bare_extraction` (text + metadata together) — the old code ran `extract()` twice (the XML pass was computed and discarded) plus `bare_extraction`, three full parses per page. `extract_batch` caps full-page extractions per call (default 8; overflow URLs return unsuccessful so the web leg falls back to the search snippet), responses are capped at 5MB before parsing, and thread-pool queue depth is logged for backpressure visibility.
+- **Top-k enrichment with one batched lookup** - Phase 3 (`_enrich_with_related_dossiers`) ran a sequential Neo4j round-trip for EVERY fused result and the final trim then discarded most of the output. It now enriches only the results that can still reach the response (the Phase 4 rerank slice of 20 when reranking is enabled, otherwise `final_result_count`) and resolves all of them in ONE UNWIND-batched Cypher query (`GraphService.get_related_documents_batch`, tenant-scoped like the single-page variant, per-page ordering/limit preserved). Unenriched tail results carry an empty `related_dossiers` list as before.
+- **Search persistence off the hot path, one atomic transaction** - HybridRAG Phase 6 (`_persist_search_for_librarian`) no longer gates the `/query/hybrid` response: the `search_id` is generated up front and returned immediately while the Neo4j write runs as a background task (strong task references held so tasks are not GC'd mid-flight). The write itself collapsed from ~21+ sequential auto-commit queries (SearchQuery node + per-document FOUND links + per-web-result WebResult nodes) into ONE UNWIND-based `execute_write` transaction, so a mid-way failure can no longer leave a partial SearchQuery graph behind. The persisted shape (SearchQuery properties incl. `processed: false`, tenant labels, `FOUND` relationship properties, WebResult properties) is unchanged and pinned by `tests/test_search_persistence.py` against exactly what the consolidation service queries. `timing.persistence_ms` now reports 0 (no longer on the request path).
+- **Batched embeddings + delete-last reindex** - `OllamaClient.embed_batch` now sends ONE batched `/api/embed` request (verified against the live Ollama; the old "batch" looped one `/api/embeddings` call per chunk) with a per-text fallback preserving partial-success semantics. `VectorService.update_from_page` embeds all chunks in that single call and upserts them in one Qdrant batch, and the reindex order is reversed: new points are upserted BEFORE stale points are pruned (deterministic uuid5 chunk ids make the overwrite safe), so a mid-way failure can no longer leave a page with zero vectors — the old order deleted everything first. The summary now reports `status` (`success`/`partial`/`failed`) and `chunks_skipped` instead of unconditional `success=True`; a fully failed embedding pass keeps the old vectors and reports failure. Measured on a real 7-chunk page ingest as `llm_tester` against the local server: ~375ms → ~181ms median (3 runs each).
+- **Document sync indexing fixed** - `DocumentSyncService._index_vectors` now awaits `ensure_collection` (the coroutine was created but never ran, so fresh tenants had no collection at upsert time), filters out `None` entries from `embed_batch` so one failed chunk embedding no longer aborts the whole document upsert (all-failed still reports failure), and routes the raw `client.delete`/`client.upsert` calls through the async wrapper (`delete_by_filter` / new batch `upsert_points`). Offline unit tests added.
+- **Async Qdrant client** - `QdrantClientWrapper` now uses `AsyncQdrantClient` with an explicit timeout (`QDRANT_TIMEOUT`, default 30s). Every vector call previously ran on the synchronous client inside async wrapper methods, blocking the FastAPI event loop for the duration of each Qdrant round-trip. The wrapper API is unchanged (all methods were already `async`), so call sites only gained real awaits. The HybridRAG document leg was moved off the deprecated raw `client.search` onto the wrapper's `search_vectors` (fixing a latent `AttributeError`: it called the nonexistent `ollama.embed_text`, so the leg always reported `failed`), and the health check awaits `get_collections`.

+- **BREAKING: `user` is now required on every tenant-data endpoint** - The implicit `jpmschweitzer` default tenant (`DEFAULT_USER`) has been removed everywhere. All endpoints that read or write tenant data (`/query/*`, `/wiki/*`, `/vector/*`, `/graph/*`, `/ingest/*`, `/volatile/*`, `/documents/*`, `/stats`, `/rag/search`) now reject requests without an explicit, non-empty, non-whitespace `user` (HTTP 422), matching the existing `/maintenance/*` pattern. A shared validator (`require_user` dependency / `RequiredUser` model type) also rejects blank users. The Wiki.js change listener now skips changes whose notification email yields no user instead of attributing them to the production tenant. **Caller coordination required:** tatlock and the Scheduler ingest/prefetch/consolidation tasks must send an explicit `user` on every call — see the deploy checklist.
+
+### Fixed (security)
+
+- **Cross-tenant leaks in HybridRAG legs and ingestion closed** - A live probe as `user=llm_tester` returned `jpmschweitzer` pages. Root causes fixed:
+  - **Ingestion namespace enforcement**: `vector` and `graph` `update_from_page` now refuse pages whose wiki path is outside `users/{user}/` (previously any tenant could ingest any page id — including another tenant's — into its own collection/labels, which is how foreign content ended up in the vector leg). `/ingest/all` clamps `path_prefix` to the caller's namespace (400 on cross-tenant prefixes) and defaults to `users/{user}`.
+  - **Search persistence**: the `FOUND` link in HybridRAG phase 6 matched `(d:Document {page_id})` unscoped, attaching the caller's SearchQuery to other tenants' Document nodes; it now matches only `User_{Tenant}_Document` nodes.
+  - **Graph enrichment/consolidation queries scoped**: `_get_entity_mention_count`, entity-stub generation, orphan-entity find/purge, and `cleanup_broken_relationships` matched unscoped `Document`/`SearchQuery` nodes; all now use the tenant's labels. Entity-page existence checks list only the tenant's wiki namespace.
+  - **Volatile collections sanitized**: `volatile_{user}` collection names now use the sanitized user id (same scheme as document collections).
+  - **Namespace matching hardened**: `is_path_in_user_namespace` now enforces a path-segment boundary (`users/llm_tester2` is no longer inside `llm_tester`'s namespace) and compares sanitized tenant segments.
+  - Offline unit tests added per leg (vector, graph, volatile, documents, enrichment, persistence, ingestion) asserting the tenant-scoped collection/label/path is used.
+
+- **`/query/graph` and `/graph/query` hardened to read-only** - The documented "automatic user scoping" was a no-op (a live probe confirmed any user string could read the whole graph) and the client permitted writes. Raw Cypher queries are now (1) rejected with 400 when they contain write clauses (`CREATE`/`MERGE`/`DELETE`/`DETACH`/`SET`/`REMOVE`/`DROP`/`FOREACH`/`LOAD CSV`) or any `CALL` procedure (conservative denylist on the uppercased query), and (2) executed through a Neo4j session opened with `default_access_mode=READ_ACCESS` so the database itself refuses writes as a backstop. The endpoints are now honestly documented as **admin/debug, unscoped read-only**: results are not restricted to the caller's tenant labels — use `/graph/nodes` for tenant-scoped access.
+
+### Added
+
+- **Degradation signaling** - `HybridRAGResponse` now includes `source_status` (per-leg `'ok'`/`'failed'`/`'disabled'` for vector, graph, web, volatile, documents) and `degraded` (true when any enabled leg failed). Retrieval legs report errors instead of silently swallowing them; failed legs are logged at WARNING. Both fields are additive and optional, so clients that ignore them are unaffected.
+- **Hard-isolated test-tenant lifecycle for the test suite** - `tests/conftest.py` rewritten: the production host default (`192.168.86.149`) is gone (`TEST_HOST` env, safe `localhost` default; the API under test is the local wakeup server via `LIBRARY_DESK_URL`, never the production container on 8089). The suite is pinned to the reserved test tenant `llm_tester`; a session guard aborts the entire run if the effective tenant is `jpmschweitzer` or outside the reserved `llm_tester*` namespace. Integration tests are marked and only run with `RUN_INTEGRATION_TESTS=1` (plus a passing guard). A session-scoped teardown deletes ALL `llm_tester` artifacts created during the run — Qdrant `*_llm_tester` collections, Neo4j `User_Llm_Tester*`-labelled nodes, the `users/llm_tester` wiki subtree, and `llm_tester` Redis keys on the service DB — with hard tenant assertions before every delete. Legacy integration tests were pinned to the test tenant (no more production-namespace reads).
+- **Live tenant-isolation test** - `tests/test_tenant_isolation_live.py` (integration-marked, guard-gated): creates and ingests a wiki page as `llm_tester` against the local wakeup server + shared services, asserts `/query/hybrid` as `llm_tester` retrieves its own content with ZERO results from the `jpmschweitzer` tenant, and asserts a third nonexistent tenant (`llm_tester_void`, still inside the reserved namespace — nothing is ever written as `jpmschweitzer`) gets zero results entirely. Teardown removes everything it created.
+- **Test-residue purge tooling** - `scripts/purge_test_artifacts.py`: dry-run by DEFAULT (`--execute` required for real deletion), targets only confirmed test residue (Qdrant `library_desk_llm_tester` / `test_user` / `library_desk_test_user` / `memories_llm_tester` / `volatile_llm_tester` / `core_ai_user_test_*` / anything containing `llm_tester`; Neo4j `User_Llm_Tester*`-labelled nodes and legacy `users/llm*` Document nodes; `llm_tester` Redis keys on the service DB), prints counts per target, hard-aborts if any target rule ever matches a `jpmschweitzer`-namespaced identifier, and documents the snapshot prerequisite (Qdrant snapshot API + `neo4j-admin database dump`) in its docstring.
+- **Offline unit tests** - New mock-based tests (no live services) for model-name resolution under the env collision, per-leg failure signaling, the `/stats` page-count prefix, LLM-call timeouts, and Wiki.js listing pagination.
+
+### Fixed
+
+- **Ollama generation model env collision** - Renamed the generation-model setting `ollama_model` to `ollama_llm_model` (env: `OLLAMA_LLM_MODEL`, default `gemma4:e2b`). The container env `OLLAMA_MODEL=nomic-embed-text` (meant for embeddings) was shadowing the generation model, breaking Phase 0 keyword extraction and Phase 4 LLM re-ranking on every request. Startup now logs the resolved generation model.
+- **LLM call timeouts** - Phase 0 keyword extraction and Phase 4 re-ranking are wrapped in a 12s `asyncio.wait_for` with graceful fallback, so a hung Ollama call can no longer gate retrieval for the full 120s client timeout.
+- **`/stats` wiki page count** - The endpoint passed the bare user name as path prefix (matching nothing) and always reported 0 pages; it now counts pages under `users/{user}`.
+- **Wiki.js page listing** - `list_pages` applied the API-side `limit` before client-side path/tag filters, dropping matching pages that sort late; the limit now applies after filtering. `list_all_pages` replaced its fake pagination loop with a real limit-growth loop (Wiki.js 2.x `pages.list` has no offset argument) that fetches until the API returns fewer pages than requested.
+- **Consolidation loop silently drained its queue on LLM failure** - Root cause of the 30-minute knowledge-consolidation loop processing 0 searches ("No unprocessed searches found" in prod): the `OLLAMA_MODEL` env collision (see below) made every consolidation `/api/generate` call fail with HTTP 400 (`"nomic-embed-text" does not support generate` — confirmed in prod logs and by direct Ollama probe), classification returned empty, and the loop STILL marked every SearchQuery `processed: true` — permanently consuming the queue with zero pages ever created (live Neo4j: 197/200 SearchQuery nodes processed with no output). LLM-infrastructure failure now raises `ConsolidationLLMUnavailableError`: the affected searches stay unprocessed (retried next run), the batch aborts after the first failure, and the response reports `searches_deferred`. Every run now logs `searches_processed` and `duration_ms` (also new response fields). The lookback boundary is now timezone-aware UTC. Regression tests added.
+- **Wiki.js `update_page` without tags** - Wiki.js 2.x requires `tags` on the update mutation (the server unconditionally maps over it); every `update_page(page_id, content=...)` call without tags failed with `Cannot read properties of undefined (reading 'map')` — this silently broke the consolidation service's page-update path too. The client now preserves the page's current tags when the caller does not supply any.
+- **Wiki.js listing completeness under pre-filter limits** - Observed live: `pages.list(limit=100)` returned 43 pages while 140 existed (`limit=500` returned all) — Wiki.js applies the limit BEFORE its own visibility filtering, so "fewer pages than requested" does not mean the listing is complete and the limit-growth loop stopped early, silently truncating listings (page counts, cleanups, integrity scans). The loop now grows the limit until the returned count stops increasing (fixed point), at the cost of one confirming fetch.

-# Claude Code Instructions
+# CLAUDE.md — Library Desk
 
-**MANDATORY: Read AGENTS.md instead of this file.**
+FastAPI service that ingests Wiki.js content and serves retrieval over it. Talks to
+Postgres (Wiki.js DB + `LISTEN/NOTIFY`), Qdrant (vectors), Neo4j (graph), Ollama
+(embeddings) and Redis (job manager). Deployed on tower-of-joy at **:8089**.
 
-This project uses a unified configuration file for all LLM coding agents.
+## Ports — these differ, deliberately
 
-## Instructions
+| | Port | How |
+|---|---|---|
+| Local dev | **8778** | `./wakeup.sh`, uvicorn reload mode, logs to `logs/server.log` |
+| Production | **8089** | container; health at `http://192.168.86.149:8089/health` |
 
-1. **Read and follow AGENTS.md** - All project guidelines are located there
-2. **Do not modify this file** - Only update AGENTS.md
-3. **Do not create or modify other agent-specific files** - Use AGENTS.md as the single source of truth
+Testing `localhost:8089` on the dev box hits the *container*, not your reload server.
 
-This approach ensures consistent behavior across all LLM coding agents without managing separate configuration files.
+## Work tracking
 
----
+Work lives in **pql**, not a markdown file. `TODO.md` was migrated and removed 2026-08-08.
 
-If you need to update project guidelines, edit AGENTS.md, not this file.
+```bash
+pql ticket list                    # open work
+pql plan whatsnext                 # next unblocked item, with context
+pql ticket show T-1                # detail
+pql ticket new bug "title"         # file new work
+```
+
+Tickets travel with the repo — `.pql/changelog/` is committed and replayed by the git
+hooks; the databases are ignored and rebuildable with `pql plan rebuild`. Do not add a
+TODO section to a markdown file.
+
+## Known live defect
+
+**Every wiki page change is ingested twice** (T-1, proven against v1.9.1). The Dockerfile
+runs `uvicorn --workers 2`, `startup_event` creates a `WikiChangeListener` per worker, and
+Postgres delivers `NOTIFY` to *every* listening session. The debounce in
+`wiki_change_listener.py` is an in-process dict and cannot dedupe across workers.
+
+Relevant when touching ingestion: duplicate work reaches Ollama, Qdrant and Neo4j. Whether
+it merely wastes GPU or actually corrupts state is **not yet established** — check before
+assuming either.
+
+## Working here
+
+**Plan, act, reflect.** Outline which files you will touch and the side effects before
+writing. Change in small atomic steps. Afterwards, verify: did existing tests break, and
+does the new behaviour have a test?
+
+**Test locally first — the build-deploy loop is slow.** `./wakeup.sh` auto-reloads on code
+changes (not on `requirements.txt` changes). Deploy only when a feature is complete and
+tested.
+
+Run tests through the venv explicitly, to avoid environment mismatch:
+
+```bash
+.venv/bin/python -m pytest tests/
+```
+
+Copy `.env.example` to `.env` and configure Ollama, Redis, Neo4j, Qdrant and Wiki.js hosts.
+
+## Git
+
+- **History is linear — no merge commits.** Work on `main`, or a short-lived branch that is
+  fast-forwarded and deleted. (A feature-branch mandate was retired 2026-08-08 to match the
+  workspace convention, which now has no per-repo exceptions.)
+- **Conventional Commits**: `feat:`, `fix:`, `refactor:`, `docs:`, `chore:`.
+- **Atomic commits** — one logical change each.
+- **Stage explicitly. Never `git add -A`** — it is denied by policy, and it sweeps in
+  whatever else is dirty, including secrets.
+- Update `CHANGELOG.md` with every user-facing change, under `[Unreleased]` in `Added` /
+  `Changed` / `Fixed`.
+
+## Releasing
+
+Ask whether a deploy is wanted first — it is not automatic.
+
+1. Bump the version in `pyproject.toml` (patch for fixes, minor for features).
+2. Move `[Unreleased]` entries into a dated version section in `CHANGELOG.md`.
+3. Stage the changed files by name, commit, tag `vX.Y.Z`, `git push origin main --tags`.
+4. Gitea CI builds the image on the tag; Watchtower deploys it.
+5. Verify: `curl http://192.168.86.149:8089/health`.
+
+## Architecture
+
+Group by **domain, not by file type**. A single large `routers/` folder is the thing to
+avoid.

-## Stub Endpoints to Implement
-
-The following endpoints in `src/main.py` return stub responses and need real implementations:
-
-### Ingestion Status Endpoints
-
-#### `POST /ingest/check-updates`
-Check which documents need updating based on content hashes. Used by Scheduler to determine what changed since last sync.
-
-**Implementation needed:**
-1. Query existing documents by path
-2. Compare content hashes
-3. Return list of updates needed
-
-#### `GET /ingest/status/{document_id}`
-Get processing status for a document.
-
-**Implementation needed:**
-- Status tracking system (Redis or database)
-- Track ingestion progress per document
-
-#### `GET /ingest/repo-status/{repository}`
-Get indexing status for an entire repository.
-
-**Implementation needed:**
-- Repository-level statistics
-- Track which documents from a repo are indexed
-
-### Deduplication
-
-#### `POST /deduplicate/check`
-Check for duplicate or highly similar documents using vector similarity and graph analysis.
-
-**Implementation needed:**
-1. Get document embedding from Qdrant
-2. Find similar vectors above threshold
-3. Check graph relationships
-4. Return candidates with similarity scores
-
-## System Statistics
-
-#### `GET /stats`
-Get system statistics (wiki pages, neo4j nodes, qdrant vectors).
-
-**Implementation needed:**
-- Query Neo4j for node count
-- Query Qdrant for vector count
-- Query Wiki.js for page count

+
+**File handling by type:**
+
+| File Type | Paperless | Library Desk |
+|-----------|-----------|--------------|
+| PDFs | OCR → text | Index text → vectors/graph |
+| Images | OCR → text | Index text → vectors/graph |
+| Videos | Storage only | Index metadata → vectors/graph |
+
+---
+
+## Technology Stack
+
+| Component | Purpose | Rationale |
+|-----------|---------|-----------|
+| **Paperless-ngx** | Document storage + OCR | All-in-one: storage, OCR, web UI, REST API |
+| **ClamAV** | Virus scanning | Host OS install, pyclamd integration, better isolation |
+| **PDF.js** | PDF viewer | Embeddable in Wiki.js (deferred) |
+
+**Why Paperless-ngx as primary store:**
+- Eliminates need for separate blob storage (SeaweedFS/MinIO)
+- Built-in web UI for browsing and tagging
+- Tesseract OCR with 100+ language support
+- REST API for Library Desk integration
+- Handles videos as raw files (no OCR, but stored)
+- Email and folder watching for automatic ingestion
+- Active community, well-maintained
+
+---
+
+## Paperless-ngx API Deep Dive
+
+### Authentication
+```
+POST /api/token/
+Body: {"username": "...", "password": "..."}
+Response: {"token": "..."}
+
+Header: Authorization: Token <token>
+```
+
+### Document Upload (for HybridRAG → Paperless)
+```
+POST /api/documents/post_document/
+Content-Type: multipart/form-data
+
+Fields:
+- document (file, required)
+- title (string)
+- created (datetime)
+- correspondent (ID)
+- document_type (ID)
+- storage_path (ID)
+- tags (repeatable IDs)
+- custom_fields (JSON array)
+
+Response: {"task_id": "uuid"}
+```
+
+Track consumption: `GET /api/tasks/?task_id={uuid}` → returns document ID when complete
+
+### Document Search
+```
+GET /api/documents/?query=search+terms     # Full-text search
+GET /api/documents/?more_like_id=123       # Similarity search
+
+Response includes __search_hit__:
+{
+  "score": 0.95,
+  "highlights": "<span>matched</span> text",
+  "rank": 0
+}
+```
+
+### Custom Field Filtering
+```
+GET /api/documents/?custom_field_query=field_name__operation=value
+
+Operations:
+- exact, in, isnull, exists (all types)
+- icontains, istartswith, iendswith (text)
+- gt, gte, lt, lte, range (numeric/date)
+- contains (document links)
+```
+
+### Bulk Operations
+```
+POST /api/documents/bulk_edit/
+{
+  "documents": [1, 2, 3],
+  "method": "add_tag|remove_tag|set_correspondent|set_document_type|merge|split|...",
+  "parameters": {...}
+}
+```
+
+### Webhooks (Push to Library Desk!)
+Paperless workflows can trigger webhooks on document events:
+
+| Trigger | When | Available Data |
+|---------|------|----------------|
+| Consumption Started | Before OCR | file_path, source, filename |
+| Document Added | After OCR | content, tags, doc_type, correspondent, `{doc_url}` |
+| Document Updated | On change | Same as Added |
+| Scheduled | Time-based | Date offsets from document dates |
+
+**Webhook Action**: POST to Library Desk endpoint with document data
+
+### Organization Features
+
+| Feature | Purpose | API Endpoint |
+|---------|---------|--------------|
+| Tags | Nested labels (5 levels deep) | `/api/tags/` |
+| Correspondents | Source/destination | `/api/correspondents/` |
+| Document Types | Classification | `/api/document_types/` |
+| Storage Paths | File organization | `/api/storage_paths/` |
+| Custom Fields | Extensible metadata | `/api/custom_fields/` |
+
+### Custom Fields We Should Create
+| Field Name | Type | Purpose |
+|------------|------|---------|
+| `source_url` | URL | Original download URL (for HybridRAG uploads) |
+| `library_indexed` | Boolean | Sync status with Library Desk |
+| `library_doc_id` | Text | Library Desk document reference |
+| `collection` | Text | Logical grouping (e.g., "fastapi-docs") |
+
+### External LLM Add-ons (Optional)
+Community tools exist for Ollama integration:
+- **[paperless-ai](https://github.com/clusterzx/paperless-ai)** - Auto-tagging, RAG chat
+- **[paperless-gpt](https://github.com/icereed/paperless-gpt)** - LLM-enhanced OCR, auto-titling
+
+**Recommendation:** Skip these - Library Desk already has Ollama integration for:
+- Embedding (nomic-embed-text)
+- LLM analysis (mistral-nemo)
+- Entity extraction
+- HybridRAG
+
+We'll do our own classification/tagging via Library Desk after sync.

+          Upload to Paperless         Reject + Log
+```
+
+### ClamAV Deployment (Host OS)
+
+ClamAV runs on the host OS (not containerized) for better security isolation:
+
+```bash
+# Installed via apt on Ubuntu/Debian
+# Config: /etc/clamav/clamd.conf
+# TCPSocket 3310
+# TCPAddr 0.0.0.0
+```
+
+Benefits: scans outside container isolation, single virus DB, survives container restarts.
+
+### Library Desk Integration
+```python
+# src/clients/clamav_client.py
+import pyclamd
+
+class ClamAVClient:
+    def __init__(self, host: str, port: int = 3310):
+        self.cd = pyclamd.ClamdNetworkSocket(host, port)
+
+    async def scan_bytes(self, data: bytes) -> ScanResult:
+        """Scan file bytes, return clean/infected status."""
+        result = self.cd.scan_stream(data)
+        if result is None:
+            return ScanResult(clean=True)
+        return ScanResult(clean=False, virus_name=result['stream'][1])
+
+    def ping(self) -> bool:
+        """Health check."""
+        return self.cd.ping()
+```
+
+### Scan Points
+| Location | When | Action on Infected |
+|----------|------|-------------------|
+| `/documents/upload` | Before Paperless upload | Reject with 400, log threat |
+| HybridRAG web fetch | Before saving PDF | Skip file, log threat |
+| `/documents/webhook` | Optional re-scan | Quarantine in Paperless |
+
+### Config Settings
+```python
+# src/config.py
+CLAMAV_HOST: str = "192.168.86.149"  # Host OS IP (not container)
+CLAMAV_PORT: int = 3310
+CLAMAV_ENABLED: bool = True  # Bypass for testing
+CLAMAV_TIMEOUT: int = 30  # seconds
+```
+
+---
+
+## Integration Strategy
+
+### Option A: Webhook Push (Preferred)
+```
+Paperless Workflow → POST webhook → Library Desk /documents/webhook
+```
+- Real-time indexing when documents added/updated
+- Configure in Paperless: Workflow → Document Added → Webhook Action
+- Library Desk receives document ID, fetches content via API
+
+### Option B: Polling Pull (Fallback)
+```
+Scheduler → POST /documents/sync → Library Desk polls Paperless
+```
+- Periodic sync for missed webhooks or initial bulk import
+- Track `library_indexed` custom field to skip already-processed docs
+
+### Option C: HybridRAG Upload (New!)
+```
+HybridRAG web search → finds PDF → POST to Paperless → webhook → indexed
+```
+- When HybridRAG finds a relevant PDF/document in web results
+- Download and upload to Paperless with `source_url` custom field
+- Paperless OCRs it, triggers webhook, Library Desk indexes
+
+---
+
+## Library Desk API Design
+
+### Documents Router (`/documents`)
+
+| Endpoint | Method | Purpose |
+|----------|--------|---------|
+| `/documents/webhook` | POST | Receive Paperless webhook (Document Added/Updated) |
+| `/documents/sync` | POST | Pull new/updated docs from Paperless → index |
+| `/documents/upload` | POST | Upload file to Paperless (for HybridRAG) |
+| `/documents/sync-from-git` | POST | Pull docs from Gitea → upload to Paperless → index |
+| `/documents/{document_id}` | GET | Get document metadata |
+| `/documents/{document_id}/text` | GET | Get extracted text |
+| `/documents/search` | POST | Semantic search across documents |
+| `/documents/collection/{name}` | GET | List documents in collection |
+| `/documents/collection/{name}/catalog` | POST | Generate wiki catalog page |
+
+**Upload flow (HybridRAG → Paperless):**
+1. HybridRAG finds PDF in web results
+2. POST `/documents/upload` with URL or file
+3. Library Desk downloads, uploads to Paperless with metadata
+4. Returns task_id for async tracking
+5. Paperless webhook triggers indexing when OCR complete
+
+### Viewers Router (`/viewers`) - Deferred
+
+| Endpoint | Method | Purpose |
+|----------|--------|---------|
+| `/viewers/pdf/{document_id}` | GET | Serve PDF.js viewer |
+| `/viewers/image/{document_id}` | GET | Serve image lightbox |
+| `/viewers/video/{document_id}` | GET | Serve Video.js player |
+
+---
+
+## Data Flow: Document Processing Pipeline
+
+```
+1. INTAKE (Paperless-ngx handles this)
+   └─ Upload via Paperless UI, email, or folder watch
+   └─ Paperless assigns document ID and stores file
+
+2. OCR EXTRACTION (Paperless-ngx handles this)
+   ├─ PDFs → Tesseract → Plain text
+   ├─ Images → Tesseract → Plain text
+   └─ Videos → Metadata only (no OCR)
+
+3. SYNC TO LIBRARY DESK (scheduled or manual)
+   └─ Poll Paperless API for new/updated documents
+   └─ Fetch text content + metadata
+
+4. TEXT CHUNKING
+   └─ VectorService._chunk_text() (existing)
+
+5. EMBEDDING
+   └─ OllamaClient.embed() (existing)
+
+6. VECTOR STORAGE (Qdrant)
+   └─ Payload: {doc_type: "document", paperless_id, ...}
+
+7. GRAPH STORAGE (Neo4j)
+   └─ Document node + MENTIONS relationships
+
+8. WIKI CATALOG (optional)
+   └─ Auto-generate catalog page via ConsolidationService
+```
+
+---
+
+## Git Docs Integration
+
+Extends existing `scheduler/src/executors/doc_sync_executor.py`:
+
+1. **Scheduler** syncs docs from GitHub → Gitea (existing)
+2. **Post-sync hook** calls `POST /documents/sync-from-git`
+3. **Library Desk** indexes docs into vectors/graph
+4. **Auto-generate** wiki catalog page for collection
+
+---
+
+## Wiki.js Viewer Integration
+
+Since Wiki.js v2 requires disabled HTML sanitization for iframes:
+
+```markdown
+<!-- In wiki catalog page -->
+## Document Preview
+
+<iframe
+  src="http://library-desk:8089/viewers/pdf/abc123"
+  width="100%" height="600px">
+</iframe>
+```
+
+**Wiki.js Settings Required:**
+- `Administration > Security > Allowed HTML Elements: iframe`
+- `Content Security Policy: frame-src http://library-desk:8089`
+
+---
+

+# Memory "Remember" Triggers - Implementation Plan
+
+## Overview
+
+This document outlines the implementation of "remember" triggers for the memory system. Currently, we have recall (search) working for volatile and documents, but no automated triggers to populate these memory tiers.
+
+**Key architectural principle:**
+- **Scheduler-driven**: Prefetch data that's useful on a repeating schedule (weather, news)
+- **HybridRAG-driven**: Cache ad-hoc ephemeral data discovered during searches
+- **Learning loop**: HybridRAG can register scheduler tasks when it discovers prefetch-worthy patterns
+
+---
+
+## Current State
+
+| Memory Tier | Remember Trigger | Recall | Status |
+|-------------|------------------|--------|--------|
+| Wiki | Wiki.js webhook, Consolidation | HybridRAG vector+graph | ✅ Complete |
+| Documents | Paperless webhook | HybridRAG document search | ✅ Complete (v1.6.0) |
+| Volatile | Scheduler prefetch, HybridRAG post-processor | HybridRAG volatile search | ✅ Complete (v1.6.0) |
+
+### Implementation Summary (v1.6.0)
+
+- **Settings DB**: Central `system_settings` PostgreSQL database with `SettingsClient`
+- **Phase A**: Volatile fetch endpoints (`/volatile/fetch/{namespace}/{key}`) with weather, news, financial providers
+- **Phase B**: Unified memory routing in consolidation service (wiki/volatile/file/prefetch/skip classification)
+- **Phase C**: Document recall in HybridRAG (4-source parallel retrieval)
+- **Scheduler Integration**: `SchedulerClient` for external scheduler task registration
+
+---
+

+## Central Settings Database
+
+### Rationale
+
+External API credentials (NewsAPI, etc.) and configs (Open-Meteo) should NOT be in environment variables because:
+- They're not deployment-specific (same across all environments)
+- They change independently of deployments
+- Multiple services across Tatlock need access to shared credentials
+- Environment variables require container restarts to update
+
+### Database Choice: PostgreSQL
+
+**Decision:** Use `postgres-shared` container (existing Tatlock infrastructure).
+
+Create a new database `system_settings` on the shared PostgreSQL instance. This container exists specifically for cross-service databases.
+
+### Schema Design
+
+```sql
+-- Run on postgres-shared as admin user
+
+-- Create database
+CREATE DATABASE system_settings;
+
+-- Create settings user (shared across all Tatlock services)
+CREATE USER settings WITH PASSWORD 'changeme';
+GRANT ALL PRIVILEGES ON DATABASE system_settings TO settings;
+
+-- Connect to system_settings database
+\c system_settings
+
+-- Create table
+CREATE TABLE settings (
+    key VARCHAR(255) NOT NULL,
+    user_scope VARCHAR(100) NOT NULL DEFAULT 'global',  -- 'global' or specific username
+    value JSONB NOT NULL,
+    schema JSONB,              -- JSON Schema for UI rendering (nullable)
+    description TEXT,
+    updated_at TIMESTAMP DEFAULT NOW(),
+    updated_by VARCHAR(100),
+    PRIMARY KEY (key, user_scope)
+);
+
+-- Index for user-scoped lookups
+CREATE INDEX idx_settings_user_scope ON settings(user_scope);
+
+-- Grant full access
+GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO settings;
+```
+
+### Query Pattern
+
+```sql
+-- Get setting with user override, fallback to global
+SELECT value, schema FROM settings
+WHERE key = $1 AND user_scope IN ($2, 'global')
+ORDER BY CASE WHEN user_scope = $2 THEN 0 ELSE 1 END
+LIMIT 1;
+```
+
+### Data Types with JSON Schema
+
+The `schema` column contains JSON Schema for UI widget rendering:
+
+| JSON Schema | UI Widget |
+|-------------|-----------|
+| `{"type": "string", "format": "password"}` | Masked input |
+| `{"type": "string", "enum": [...]}` | Dropdown/select |
+| `{"type": "boolean"}` | Toggle switch |
+| `{"type": "array", "items": {"type": "string"}}` | Multi-select or list |
+| `{"type": "number", "minimum": 0, "maximum": 100}` | Slider or number input |
+| No schema | Raw JSON editor |
+
+### Example Data
+
+```sql
+-- Global API keys (with schemas for CRUD UI)
+INSERT INTO settings (key, user_scope, value, schema, description) VALUES
+('api.openmeteo', 'global',
+ '{"base_url": "https://api.open-meteo.com/v1/forecast", "timezone": "Europe/Amsterdam"}',
+ '{
+   "type": "object",
+   "properties": {
+     "base_url": {"type": "string", "format": "uri", "title": "Base URL"},
+     "timezone": {"type": "string", "title": "Default Timezone"}
+   }
+ }',
+ 'Open-Meteo weather API (no API key required)'),
+
+('api.newsapi', 'global',
+ '{"api_key": "xxx"}',
+ '{
+   "type": "object",
+   "properties": {
+     "api_key": {"type": "string", "format": "password", "title": "API Key"}
+   },
+   "required": ["api_key"]
+ }',
+ 'NewsAPI.org credentials'),
+
+('api.nos_rss', 'global',
+ '{"feed_url": "https://feeds.nos.nl/nosnieuwsalgemeen"}',
+ '{
+   "type": "object",
+   "properties": {
+     "feed_url": {"type": "string", "format": "uri", "title": "Feed URL"}
+   }
+ }',
+ 'NOS.nl RSS feed');
+
+-- User-specific preferences (explicit choices)
+INSERT INTO settings (key, user_scope, value, schema, description) VALUES
+('weather.units', 'jpmschweitzer',
+ '"metric"',
+ '{"type": "string", "enum": ["metric", "imperial"], "title": "Temperature Units"}',
+ 'Preferred temperature units'),
+
+('news.sources', 'jpmschweitzer',
+ '["nos", "reuters"]',
+ '{
+   "type": "array",
+   "items": {"type": "string"},
+   "uniqueItems": true,
+   "title": "News Sources"
+ }',
+ 'Preferred news sources');
+```
+
+### What Goes Where
+
+| Data Type | Storage | Examples |
+|-----------|---------|----------|
+| **API credentials/config** | Settings DB (global) | `api.openmeteo`, `api.nos`, `api.alphavantage` |
+| **Explicit user preferences** | Settings DB (user-scoped) | `weather.units`, `news.sources` |
+| **Learned user facts** | Biographer knowledge graph | Location, interests, schedule |
+| **Internal service URLs** | ENV vars | `SCHEDULER_URL`, `REDIS_HOST` |
+
+**Key principle:** Settings DB stores explicit choices. Biographer stores learned context.
+
+**Example flow for weather fetch:**
+1. Scheduler triggers `/volatile/fetch/weather`
+2. Fetch service queries biographer: "Where does this user live?"
+3. Biographer returns "Rotterdam" from knowledge graph
+4. Fetch service reads `weather.units` preference from settings
+5. Calls Open-Meteo API (geocode city → lat/long → forecast) with units from settings
+6. Stores result in volatile cache
+
+### Library-Desk Integration
+
+**ENV vars (deployment-specific only):**
+```bash
+# Central settings database
+SYSTEM_SETTINGS_HOST=postgres-shared
+SYSTEM_SETTINGS_PORT=5432
+SYSTEM_SETTINGS_DB=system_settings
+SYSTEM_SETTINGS_USER=settings
+SYSTEM_SETTINGS_PASSWORD=xxx
+
+# Internal service URLs (plumbing, not in settings DB)
+SCHEDULER_URL=http://scheduler:8080
+BIOGRAPHER_URL=http://biographer:8080
+```
+
+**New file: `src/clients/settings_client.py`**
+

+```bash
+# Connect to settings database
+psql -h postgres-shared -U settings -d system_settings
+
+# Add global API key
+INSERT INTO settings (key, value, description)
+VALUES ('api.alpha_vantage', '{"api_key": "YOUR_KEY"}', 'Alpha Vantage financial API');
+
+# Add global API key with schema for UI
+INSERT INTO settings (key, value, schema, description)
+VALUES ('api.alpha_vantage', '{"api_key": "YOUR_KEY"}',
+        '{"type": "object", "properties": {"api_key": {"type": "string", "format": "password"}}}',
+        'Alpha Vantage financial API');
+
+# Add user-specific preference
+INSERT INTO settings (key, user_scope, value, description)
+VALUES ('weather.units', 'jpmschweitzer', '"metric"', 'Preferred temperature units');
+
+# Update NewsAPI key
+UPDATE settings
+SET value = '{"api_key": "NEW_KEY"}', updated_at = NOW()

+
+---
+
+## Phase C: Document Recall in HybridRAG
+
+### C.1 Add Document Search
+
+**Modify:** `src/services/hybrid_rag_service.py`

+
+    tasks["document"] = document_search()
+```

+### C.2 Config Options
+
+```python
+enable_documents: bool = Field(default=True)
+document_limit: int = Field(default=5)
+document_threshold: float = Field(default=0.6)
+```
+
+---
+
+## Example Flow
+
+1. **User searches:** "What's the weather in Amsterdam?"
+2. **HybridRAG web search:** Returns open-meteo.com or weather site result
+3. **Post-processor classifies:** Ephemeral weather content
+4. **Immediate store:** `POST /volatile/store` (TTL: 1h)
+5. **Prefetch detection:** Matches weather pattern
+6. **Scheduler registration:** Creates task `volatile_weather_amsterdam_jpmschweitzer`
+7. **Next day 6am:** Scheduler calls `/volatile/fetch/weather/amsterdam`
+8. **Future searches:** Get cached weather from volatile
+

-### Data Model
+**Key design decisions:**
+- Vector storage in Qdrant (not Redis) for semantic search
+- Collection per user: `volatile_{user}`
+- TTL via `ttl_expiry` timestamp in payload
+- Natural language conversion for embedding structured data
+- Integrated into HybridRAG with priority boost
 
-```python
-class VolatileRecord(BaseModel):
-    key: str                           # e.g., "weather:rotterdam"
-    namespace: str                     # e.g., "weather", "news", "financial"

-    user: str                          # Multi-tenant isolation
-```
-
-**Key pattern**: `{user}:volatile:{namespace}:{key_hash}`
-
-### Implementation Order: Integration-First
-
-1. **Start with Consolidation Hook** - Understand data flow through existing system
-2. **Build Service Layer** - VolatileCacheService with Redis operations
-3. **Add API Endpoints** - REST interface for volatile data
-4. **Biographer Integration** - Query user preferences for relevance
-
-### Tasks
-
-#### 2.1 Integrate with Consolidation (FIRST)
-**New file**: `src/services/volatile_service.py`
-
-```python
-class VolatileCacheService:
-    async def get(user, namespace, key) -> Optional[VolatileRecord]
-    async def set(user, namespace, key, data, ttl, refresh_schedule=None)
-    async def delete(user, namespace, key)
-    async def list_namespace(user, namespace) -> List[str]
-    async def get_scheduled(user) -> List[VolatileRecord]  # For scheduler
-```
-
-#### 2.2 Create Volatile API Router
-**New file**: `src/routers/volatile.py`
+### Endpoints (Implemented)
 
 | Endpoint | Method | Purpose |
 |----------|--------|---------|
-| `/volatile/{namespace}/{key}` | GET | Retrieve record |
-| `/volatile/{namespace}/{key}` | POST | Store/update record |
+| `/volatile/search?q=...` | GET | Semantic search across volatile data |
+| `/volatile/store?namespace=...&key=...` | POST | Store/update record |
+| `/volatile/{namespace}/{key}` | GET | Retrieve specific record |
 | `/volatile/{namespace}/{key}` | DELETE | Remove record |
-| `/volatile/{namespace}` | GET | List keys in namespace |
-| `/volatile/scheduled` | GET | List records needing refresh |
 | `/volatile/stats` | GET | Cache statistics |
+| `/volatile/scheduled` | GET | Records needing refresh |
+| `/volatile/namespaces` | GET | List available namespaces |
+| `/maintenance/cleanup/volatile` | POST | Purge expired records |
 
-#### 2.3 Integrate with Consolidation
-**File**: `src/services/consolidation_service.py`
+### Namespaces
 
-Add relevance trigger detection:
-1. During consolidation, analyze search results for location/interest patterns
-2. Query tatlock's Biographer collection for user preferences
-3. If match found, create/update volatile refresh schedule
-
-#### 2.4 Biographer Integration
-**File**: `src/core/dependencies.py`
-

-## Files to Modify/Create
+## Phase 4: LLM Tester Data Cleanup ✅
 
-### Phase 1 (Cleanup)
-- `src/routers/maintenance.py` - Add timestamp tracking
+### Problem
+
+LLM testing creates accumulated cruft across the system:
+- Wiki.js pages under `llm-tester/` and `llm_tester/` paths
+- Graph nodes (Document, Entity) linked to test pages
+- Vector chunks in Qdrant for test content
+
+This data accumulates over time and clutters Wiki.js visually (no separate tenant scope for tests).
+
+### Solution
+
+Add a maintenance endpoint to purge all LLM tester artifacts across wiki, graph, and vectors.
+
+### Tasks
+
+#### 4.1 Identify Test Data Patterns ✅
+**Patterns matched** (security-restricted to test user namespace):
+- `users/llm-tester/*`
+- `users/llm_tester/*`
+
+#### 4.2 Add Cleanup Endpoint ✅
+**File**: `src/routers/maintenance.py`
+
+```python
+@router.post("/cleanup/test-data")
+async def cleanup_test_data(
+    dry_run: bool = Query(default=True),
+    wiki: WikiJSDep = None,
+    vector_service: VectorServiceDep = None,
+    graph_service: GraphServiceDep = None,
+    api_key: str = Depends(verify_api_key)
+):
+    """
+    Purge LLM tester data from wiki, graph, and vectors.
+
+    **Security**: Only deletes pages in the test user namespace:
+    - users/llm-tester/*
+    - users/llm_tester/*
+
+    Use dry_run=true to preview what would be deleted.
+    """
+```
+
+#### 4.3 Implementation Steps ✅
+
+1. **Wiki cleanup**: Delete pages via GraphQL mutation
+2. **Graph cleanup**: Delete Document nodes using `delete_page()` method
+3. **Vector cleanup**: Delete chunks using `delete_page_chunks()` method
+
+#### 4.4 Scheduler Integration ✅
+**Recommended schedule**: Weekly (Sunday 3:00 AM)
+
+```json
+{
+  "task_name": "test_data_cleanup",
+  "schedule": "0 3 * * 0",
+  "endpoint": "POST /maintenance/cleanup/test-data?dry_run=false",
+  "description": "Weekly cleanup of LLM test data"
+}
+```
+
+### Files to Modify
+
+- `src/routers/maintenance.py` - Add cleanup endpoint
+- `src/services/wiki_service.py` - Add bulk delete by path pattern (if needed)
+- `src/services/graph_service.py` - May need pattern-based node deletion
+- `src/services/vector_service.py` - Add pattern-based chunk deletion
+
+---
+
+## Files Modified/Created
+
+### Phase 1 (Cleanup) ✅
+- `src/routers/maintenance.py` - Timestamp tracking, cleanup endpoints
 - `src/services/graph_service.py` - Bidirectional validation
 - `src/services/vector_service.py` - Cross-reference checks
 - `LIBRARIAN_INTEGRATION.md` - Scheduler config docs

-- `src/core/dependencies.py` - Add Biographer client
-- `src/services/consolidation_service.py` - Relevance triggers
-- `tests/test_volatile.py` - **NEW**
+### Phase 2 (Volatile) ✅
+- `src/services/volatile_service.py` - Qdrant-based volatile cache

 ## Resolved Design Decisions
 
-1. **Biographer Qdrant**: Same Qdrant instance, different collection. Library-Desk queries directly.
-2. **Scheduler API**: Has REST API for task registration. Library-Desk can programmatically create refresh schedules.
-3. **External API calls**: Library-Desk routes through SearXNG for web search. Consider dedicated API integrations for high-value volatiles (weather, financial) for consistent quality.
+1. **Volatile Storage**: Qdrant vectors (not Redis) for semantic search capability
+2. **Collection Naming**: `volatile_{user}` for per-user isolation
+3. **TTL Mechanism**: `ttl_expiry` timestamp in payload, background cleanup job
+4. **HybridRAG Integration**: Volatile as third source with RRF priority boost
+5. **Biographer Qdrant**: Same Qdrant instance, different collection
+6. **Scheduler API**: Has REST API for task registration

+# Scheduler Task Definitions (Phase C deploy checklist)
+
+Production task payloads for the homelab's database-driven **Scheduler**
+service. These are **definitions only** — nothing in this repo registers
+them automatically. Register them as part of the deploy checklist, either
+via the Scheduler UI/API or with the helper script:
+
+```bash
+# Preview exactly what would be sent (default):
+SCHEDULER_URL=http://<scheduler-host>:8090 \
+    .venv/bin/python scripts/register_scheduler_tasks.py
+
+# Actually register/update the tasks (deploy checklist step):
+SCHEDULER_URL=http://<scheduler-host>:8090 \
+SCHEDULER_API_KEY=<scheduler-api-key> \
+    .venv/bin/python scripts/register_scheduler_tasks.py --execute
+```
+
+Conventions:
+
+- The Scheduler's task-management endpoints (`GET`/`POST /tasks`,
+  `PUT /tasks/{name}`) require `Authorization: Bearer $SCHEDULER_API_KEY`.
+  The registrar reads `SCHEDULER_API_KEY` from the environment for its
+  own HTTP calls (`--execute` refuses to run without it); the key is
+  never stored. This is separate from `LIBRARY_API_KEY` below, which the
+  Scheduler container needs at task **execution** time.
+
+- All tasks call the **production** library-desk container
+  (`http://library-desk:8089`) with the explicit production tenant
+  `user=jpmschweitzer` (there is no default tenant — Phase B).
+- `${LIBRARY_API_KEY}` is a literal placeholder stored in the task's
+  `auth.token` field. The Scheduler's `rest_api_executor` substitutes
+  `${ENV_VAR}` placeholders from **its own environment at execution
+  time** (it substitutes `url`/`payload`/`auth` — NOT plain `headers`),
+  so the raw key is never stored in the `scheduled_tasks.config` JSONB
+  column. The **Scheduler container** must have `LIBRARY_API_KEY` in its
+  environment. Never commit or register the real value.
+- The JSON body goes in `config.payload` (the executor ignores a `body`
+  key).
+- Schedule fields use the Scheduler's convention: `-1` = every,
+  `day_of_week`: `0` = Monday … `6` = Sunday.

+## 1. Nightly integrity check — 04:30 daily
+
+Read-only report: pages without vectors, orphaned vectors, unexpected
+Qdrant collections, Document nodes without wiki pages. Caches its result
+in Redis for the weekly quality report.
+
+```json

+
+## 2. Weekly quality report — Sunday 03:00
+
+Runs the duplicate scan, flags stale/metadata-poor pages, folds in the
+latest integrity results, and writes the dated report page to
+`users/jpmschweitzer/system/quality-reports/YYYY-MM-DD`.

+## 3. Daily Paperless orphan cleanup — 05:00
+
+Hits the **existing** cleanup endpoint (query parameters, empty payload).
+`dry_run=false` deletes vectors/graph nodes for documents that were
+removed from Paperless-ngx.
+
+```json

+      "token": "${LIBRARY_API_KEY}"
+    }
+  }
+}
+```
+
+## 4. Disable `test_example_task`
+
+Not a new task: the leftover example task must be **disabled** (not
+deleted, so its history is preserved).
+
+```
+PUT ${SCHEDULER_URL}/tasks/test_example_task
+Content-Type: application/json
+
+{"enabled": false}
+```
+
+---
+
+## Related (already registered / in-process)
+
+- `knowledge_consolidation` — every 30 minutes, POST
+  `/consolidate/knowledge` (already registered; after the Phase C
+  consolidation repair its runs log `searches_processed` and
+  `duration_ms`, and searches are no longer consumed while the LLM is
+  unavailable).
+- Redis job-set cleanup — runs **in-process** inside library-desk
+  (hourly `job_cleanup_loop` started at app startup); no Scheduler task
+  needed.

+# Decisions, Questions, Rejected
+
+This directory holds structured planning records that pql parses
+into pql.db. Each record is a `### [DQR]-N: Title` heading inside
+a markdown file. Files live in three per-type subdirectories:
+
+- `decisions/<domain>.md` — confirmed design decisions
+- `questions/<domain>.md` — open questions that may resolve into
+  decisions or rejected proposals
+- `rejected/<domain>.md` — rejected proposals (kept for the audit
+  trail)
+
+The parser infers domain from the filename stem and record type
+from the parent subdirectory.
+
+D-records that propose implementation work link to `initiative`-type
+tickets via `decision_ref`. Run `pql decisions show <id>
+--with-tickets` to inspect implementation status.
+
+## Recommended domains
+
+Start with this canonical set; create files as records land in
+each domain:
+
+- **architecture** — structural commitments (storage, layering,
+  languages, libraries)
+- **process** — team workflow (commits, branches, releases, reviews)
+- **design** — user-facing surface (UX, UI, public APIs)
+- **coding-conventions** — team-internal code shape (style, lint,
+  file layout)
+- **testing** — quality strategy (coverage, layers, gates)
+
+You might also want, project-permitting:
+
+- `accessibility` — if you ship user-facing software
+- `security` — if you handle user data or network surfaces
+- `licensing` — if you release open-source or commercial
+- `documentation` — if user-docs are non-trivial
+- `deployment` — if shipping is non-trivial
+- `performance` — if you have perf budgets / SLOs
+
+<!-- pql:records (auto-generated; do not edit manually) -->

+Purge test-tenant residue from the SHARED production services.
+
+Targets ONLY the confirmed test residue left behind by earlier test runs:
+
+  Qdrant collections
+    - library_desk_llm_tester, memories_llm_tester, volatile_llm_tester
+    - test_user, library_desk_test_user
+    - core_ai_user_test_*  (prefix)
+    - anything containing "llm_tester" / "llm-tester"
+
+  Neo4j
+    - all nodes carrying a label starting with "User_Llm_Tester"
+      (covers User_Llm_Tester, User_Llm_Tester_Document,
+       User_Llm_Tester_SearchQuery, User_Llm_Tester_WebResult and
+       sub-tenants like User_Llm_Tester_Void_*)
+    - legacy "llm-tester" Document nodes matched by path
+      (d.path STARTS WITH 'users/llm')
+
+  Redis (service DB from settings, default DB 4)
+    - keys matching *llm_tester* / *llm-tester*
+
+SAFETY
+======
+- DRY-RUN IS THE DEFAULT. Nothing is deleted unless --execute is passed.
+- The script REFUSES to touch anything namespaced to the production
+  tenant "jpmschweitzer": every candidate identifier is checked and the
+  script aborts (exit 2) if a production-namespaced identifier ever
+  matches a target rule.
+- Connection settings (hosts, credentials) come from the repo .env via
+  src.config.Settings; nothing is printed except identifiers and counts.
+
+SNAPSHOT PREREQUISITE (before any --execute run)
+================================================
+Take snapshots of both stores first so an erroneous deletion can be
+rolled back:
+
+  Qdrant  - full-storage snapshot via the snapshot API:
+              curl -X POST http://<qdrant-host>:6333/snapshots
+            (or per collection:
+              curl -X POST http://<qdrant-host>:6333/collections/<name>/snapshots)
+
+  Neo4j   - offline dump from inside the container:
+              docker exec <neo4j> neo4j-admin database dump neo4j \
+                  --to-path=/backups
+
+Only proceed with --execute after both snapshots completed successfully.

+Register the Phase C production Scheduler tasks (deploy-checklist helper).
+
+Defines the four task payloads from docs/scheduler-tasks.md:
+1. library_integrity_check          - nightly 04:30
+2. library_quality_report           - Sunday 03:00
+3. library_paperless_orphan_cleanup - daily 05:00
+4. test_example_task                - DISABLED (update, not create)
+
+SAFETY MODEL
+============
+- DRY-RUN BY DEFAULT: without --execute the script only prints the exact
+  payloads it would send. Nothing is contacted except (optionally) the
+  Scheduler health endpoint.
+- --execute performs the registration: create task if absent, update it
+  if present, and disable test_example_task.
+- The Scheduler API location comes from the environment (SCHEDULER_URL);
+  there is no hardcoded production default.
+- The Scheduler's task-management endpoints are themselves guarded by
+  Bearer auth (verify_api_key). --execute therefore requires
+  SCHEDULER_API_KEY in the environment; the registrar sends it as
+  ``Authorization: Bearer <key>`` on its own HTTP calls. It is read from
+  the environment only and never stored anywhere.
+- NO SECRET IS EVER STORED: the library-desk API key is referenced as the
+  literal placeholder ``${LIBRARY_API_KEY}`` inside the task's
+  ``auth.token`` field. The Scheduler's rest_api_executor substitutes
+  ``${ENV_VAR}`` placeholders from ITS OWN environment at execution time
+  (it substitutes url/payload/auth — NOT plain headers), so the raw token
+  never lands in the scheduled_tasks.config JSONB column. The Scheduler
+  container must therefore have LIBRARY_API_KEY in its environment.
+
+Usage:
+    # Preview (default)
+    SCHEDULER_URL=http://scheduler-host:8090 \
+        python scripts/register_scheduler_tasks.py
+
+    # Register for real (deploy checklist step)
+    SCHEDULER_URL=http://scheduler-host:8090 \
+    SCHEDULER_API_KEY=<scheduler-api-key> \

@@ -5,6 +5,20 @@ A reusable Trafilatura wrapper that can be used throughout library-desk:
 - RAG search service (extract content from search results)
 - Ingestion service (extract content from URLs)
 - Standalone endpoint (ad-hoc content extraction)
+
+Hardening notes:
+- Pages are fetched with httpx.AsyncClient under real connect/read timeouts
+  on the event loop. Only the CPU-bound Trafilatura parse runs in the thread
+  pool, so a slow server can no longer pin a worker thread for the duration
+  of a blind blocking download (trafilatura.fetch_url had no caller-side
+  timeout control and kept downloading after asyncio.wait_for gave up).
+- Trafilatura runs ONCE per document (bare_extraction returns text and
+  metadata together); the old code ran extract() twice (the XML pass was
+  computed and thrown away) plus bare_extraction — three full parses.
+- extract_batch caps the number of full-page extractions per call; overflow
+  URLs are returned as unsuccessful results so callers fall back to the
+  search-engine snippet.
+- Thread-pool queue depth is logged so extraction backpressure is visible.

+**wiki** - Stable reference content worth documenting permanently:
+- Factual information about people, places, companies, products
+- How-to guides, tutorials, technical documentation
+- Historical facts, biographies, definitions
+- Content that won't change frequently
+
+**volatile** - Ephemeral data that changes frequently:
+- Current weather conditions or forecasts
+- Latest news headlines or breaking news
+- Stock prices, exchange rates, crypto prices
+- Sports scores, live results
+- Traffic conditions, transit delays
+- Social media trends, notifications
+Use namespaces: weather, news, financial, transit, traffic, sports, social, system
+
+**file** - Downloadable documents:
+- PDF files (URLs ending in .pdf or containing /pdf/)
+- Office documents (.doc, .docx, .xls, .xlsx, .ppt)
+- Images (.jpg, .png, .gif when they're primary content)
+- CSV/data files
+- Any direct download link
+
+**prefetch** - Sources worth checking regularly:
+- News feeds or RSS sources
+- API endpoints with live data
+- Dashboards or status pages
+- Only if not already captured by volatile
+
+**skip** - Low value content:
+- Ads, paywalled content
+- Error pages, 404s
+- Duplicate or redundant results
+- Content not answering the query

+TENANT SAFETY MODEL
+===================
+There is no separate test infrastructure: integration tests run against the
+SHARED production services (Qdrant / Neo4j / Wiki.js / Redis / Wiki.js).
+Tenancy is the ONLY isolation wall, therefore:
+
+- The suite is pinned to the reserved test tenant ``llm_tester`` (env
+  ``TEST_TENANT`` may only select a tenant inside the reserved
+  ``llm_tester*`` namespace — anything else aborts the whole session).
+- The production tenant ``jpmschweitzer`` is NEVER written to. A session
+  guard hard-fails immediately if the effective tenant is the production
+  tenant or outside the reserved namespace.
+- Integration tests (marked ``integration``) only run when
+  ``RUN_INTEGRATION_TESTS=1`` is set; otherwise they are skipped. Offline
+  unit tests never contact the shared services.
+- A session-scoped teardown deletes ALL ``llm_tester`` artifacts created
+  during the run (Qdrant ``*_llm_tester`` collections, Neo4j nodes under
+  the ``User_Llm_Tester*`` labels, the ``users/llm_tester`` wiki subtree,
+  and ``llm_tester``-prefixed Redis keys on the service DB), with a hard
+  assertion on the tenant string before any delete.
+
+HOSTS
+=====
+``TEST_HOST`` selects where the shared services live. It defaults to
+``localhost`` (safe: nothing listens there unless you forwarded the
+services yourself). For live runs against the shared stack set it
+explicitly, e.g. ``TEST_HOST=192.168.86.149``.
+
+The API under test is the LOCAL wakeup server (``./wakeup.sh``, port 8778),
+selected via ``LIBRARY_DESK_URL`` (default ``http://localhost:8778``).
+NEVER point tests at the production container (port 8089).

+  with zero output. Every subsequent 30-minute run then logged
+  'No unprocessed searches found'.
+
+The repaired behavior:
+- LLM-infrastructure failure raises ConsolidationLLMUnavailableError, the
+  affected searches stay UNPROCESSED (retried next run), and the run reports
+  searches_deferred.
+- Successful classification still consumes searches.
+- Every run logs searches_processed and duration_ms.
