chore: release v1.9.1

Ships the Wiki.js change listener supervision fix. Patch release: no API
change, no migration — the listener now reconnects after a database restart
instead of going silently deaf, and /health reports its subscription state.

+## [Unreleased]
+
+## [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`.
+
+### Changed
+
+- **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.
+
+## [1.7.3] - 2026-01-07
+
+### Fixed
+
+- **Endpoint TTL defaults** - Updated all fetch endpoint defaults to match namespace TTLs (2x refresh interval)
+
+## [1.7.2] - 2026-01-07
+
+### Fixed
+
+- **Volatile TTL doubled** - TTL now 2x refresh interval to survive missed/delayed scheduler runs
+
+## [1.7.1] - 2026-01-07
+
+### Fixed
+
+- **CI workflow** - Updated Gitea Actions to trigger on tag push (matching core-api)
+
+## [1.7.0] - 2026-01-07
+
+### Added
+
+- **Combined Environment Endpoint** - `POST /volatile/fetch/environment/{city}`
+  - Fetches weather and air quality concurrently with `asyncio.gather()`
+  - Single geocode lookup shared between both API calls
+  - More efficient than calling weather and air_quality separately
+  - Reduces wall-clock time and eliminates redundant geocoding
+
+### Fixed
+
+- **Scheduler executor name** - Fixed `rest_api` → `rest_api_executor` in SchedulerTask model and register_volatile_fetch() to prevent "Executor module not found" errors
+
+## [1.6.2] - 2025-12-30
+
+### Added
+
+- **System Statistics Endpoint** - `GET /stats`
+  - Neo4j: node counts by type (Document, Entity, Collection, Search)
+  - Qdrant: collection counts, total vectors, per-collection breakdown
+  - Wiki.js: total page count
+  - Paperless: documents, tags, correspondents, document types
+
+- **Weather/Forecast Separation** - Split weather into two distinct namespaces
+  - `POST /volatile/fetch/weather/{city}` - Current conditions only (1hr TTL)
+  - `POST /volatile/fetch/forecast/{city}` - 7-day outlook (12hr TTL)
+  - Different update frequencies for efficient caching
+  - `FORECAST` namespace added to volatile namespaces
+
+### Changed
+
+- Weather namespace TTL changed from 30 minutes to 1 hour (current conditions)
+- Forecast data now stored separately with 12 hour TTL
+
+## [1.6.1] - 2025-12-30
+
+### Added
+
+- **Weather Forecast Support** - Enhanced weather fetch with 7-day daily forecasts
+  - Current conditions now include UV index
+  - Daily forecasts with high/low temps, conditions, precipitation chance, UV max
+  - Natural language text summary with multi-day outlook
+- **Sun Times Endpoint** - `POST /volatile/fetch/sun/{city}`
+  - Sunrise and sunset times (HH:MM and ISO formats)
+  - Daylight duration in seconds and hours
+  - Separate volatile namespace with 24hr TTL
+  - Useful for home automation light triggers
+- **Air Quality Endpoint** - `POST /volatile/fetch/air_quality/{city}`
+  - European and US AQI indices
+  - Pollutants: PM2.5, PM10, ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide
+  - Pollen data (grass, birch, alder) for European locations (seasonal)
+  - Hourly refresh (1hr TTL)
+- **New Base Models**
+  - `SunTimes` dataclass for sunrise/sunset data
+  - `AirQuality` dataclass with AQI and pollutants
+  - `AirQualityProvider` abstract interface
+- **New Volatile Namespace** - `SUN` for sunrise/sunset times (86400s default TTL)
+
+### Changed
+
+- Weather fetch now uses `get_forecast()` instead of `get_current()` for richer data
+- `OpenMeteoProvider` now implements both `WeatherProvider` and `AirQualityProvider`
+

+# 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.

+
+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 \

@@ -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.

+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).

+- ensure_collection is actually awaited (it used to be a bare coroutine
+  that never ran, so fresh tenants had no collection at upsert time)
+- None entries from embed_batch are filtered out instead of poisoning
+  the whole batch upsert (one failed chunk aborted the document)
+- delete-LAST reindex order (same as the wiki fix): new points are
+  upserted with deterministic uuid5 ids BEFORE stale points are pruned,
+  so a failed embedding pass can no longer leave a document with zero

+Live end-to-end test for the weekly quality report (integration, guard-gated).
+
+Runs against the LOCAL wakeup server (./wakeup.sh, port 8778 — never the
+production container on 8089) with the shared backing services, entirely
+under the reserved llm_tester tenant namespace:
+
+1. Create + ingest a wiki page as ``llm_tester`` (deliberately without tags
+   so the report has something to flag).
+2. POST /maintenance/quality-report {user: llm_tester}: asserts the report

+   folds in integrity results, and writes the dated report page under
+   users/llm_tester/system/quality-reports/YYYY-MM-DD.
+3. Fetches the written report page back from the wiki.
+4. Teardown deletes the created pages; the session-scoped teardown in
