 * **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

+  - Vector search still uses synonyms for semantic similarity
+  - Graph search uses only core keywords for exact entity matching
+
+### Added
+
+- `VECTOR_SIMILARITY_THRESHOLD` config setting (default: 0.7) to filter weak vector matches

+
+- **HybridRAG Content Extraction Enhancement**
+  - Web search results now include full extracted content via Trafilatura
+  - Falls back to original snippets if extraction fails

+
+### Changed
+
+- Added new configuration options:
+  - `SEARCH_CACHE_TTL` - Search cache TTL in seconds (default: 300)

+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
+
+This approach ensures consistent behavior across all LLM coding agents without managing separate configuration files.

+The `reconcile-index` endpoint performs full index maintenance:
+
+1. **Cleanup Phase**: Remove orphaned data
+   - Vector chunks without wiki source
+   - Graph nodes without vectors (bidirectional)
+   - Vectors without graph nodes (bidirectional)
+   - Orphan entities (no MENTIONS relationships)
+   - Broken relationships
+
+2. **Reindex Phase**: Index missing pages
+   - Wiki pages without vector embeddings
+   - Wiki pages without graph Document nodes
+
+**Scheduler Task: `library_reconcile_index`**
+
+```yaml
+Task Name: library_reconcile_index
+Description: Daily index reconciliation - cleanup orphans + reindex missing pages
+Schedule: Daily at 04:00 (after library_sync at 03:30)
+Priority: 10 (system maintenance)
+Service: library
+Executor: POST /maintenance/reconcile-index
+Configuration:
+  - LIBRARY_DESK_URL: http://library-desk:8089
+  - LIBRARY_API_KEY: ${LIBRARY_API_KEY}
+Parameters:
+  - user: jpmschweitzer
+  - dry_run: false
+Outputs:
+  - Vector orphans purged
+  - Entity orphans purged
+  - Missing pages reindexed
+```
+
+### Maintenance Endpoints
+
+| Endpoint | Method | Purpose |
+|----------|--------|---------|
+| `/maintenance/reconcile-index` | POST | **Recommended**: Full cleanup + reindex missing |
+| `/maintenance/cleanup/all` | POST | Cleanup only (orphan removal) |
+| `/maintenance/cleanup/vectors` | POST | Clean orphan vector chunks only |
+| `/maintenance/cleanup/graph` | POST | Clean orphan entities & stale docs only |
+| `/maintenance/health` | GET | Lightweight health check (for uptime monitoring) |
+| `/maintenance/health?detailed=true` | GET | Full analysis with orphan counts |
+| `/maintenance/reindex/{page_id}` | POST | Force re-index a specific page |
+
+### Health Check Modes
+
+**Lightweight (default)** - Use for frequent uptime checks (every 30s):
+```bash
+curl "http://library-desk:8089/maintenance/health?user=jpmschweitzer" \
+  -H "Authorization: Bearer ${LIBRARY_API_KEY}"
+```
+
+Returns only last cleanup timestamp and basic status (no database queries).
+

+Outstanding work items for Library Desk.
+
+## 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

+
+**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.

+```
+
+### 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)

+```
+
+### 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`
+
+---

+# HybridRAG Architecture
+
+## Overview
+
+HybridRAG combines three search sources to provide comprehensive results:
+- **Vector search** (Qdrant) - Semantic similarity via embeddings
+- **Graph search** (Neo4j) - Entity relationships in knowledge graph
+- **Web search** (SearXNG) - External web results via Trafilatura extraction
+
+## Two-Stage RRF Fusion (v1.3.0+)
+
+To ensure fair ranking between wiki and web results, we use a two-stage Reciprocal Rank Fusion:
+
+```
+Stage 1: Wiki Merge
+  vector results ─┬─→ Mini-RRF ─→ Unified wiki ranking
+  graph results  ─┘
+
+Stage 2: Final RRF
+  wiki (merged)  ─┬─→ Final RRF ─→ Combined results
+  web results    ─┘
+```
+
+**Why two stages?**
+
+Previously, wiki pages found by BOTH vector and graph received double RRF contribution, giving them an unfair 2x advantage over web results. The two-stage approach:
+1. Merges vector+graph into a single "wiki" source
+2. Wiki's internal ranking still benefits from multi-source confirmation
+3. Wiki and web compete as equals in final ranking
+
+## Configuration
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `VECTOR_SIMILARITY_THRESHOLD` | 0.7 | Minimum similarity score for vector results |
+| `HYBRID_RAG_VECTOR_LIMIT` | 10 | Max vector results |
+| `HYBRID_RAG_GRAPH_LIMIT` | 10 | Max graph results |
+| `HYBRID_RAG_WEB_LIMIT` | 5 | Max web results |
+
+## Known Limitations & Future Improvements
+
+### Vector Search Noise
+
+**Status:** Open for improvement if needed after observation period.
+
+Vector search may return generic category/index pages (e.g., "Reference", "Projects", "Places") with high similarity scores (~0.86). These pages often have similar boilerplate content leading to uniform scores.
+
+**Potential solutions if this becomes problematic:**
+1. **Raise threshold** - Increase `VECTOR_SIMILARITY_THRESHOLD` to 0.85+
+2. **Page-type filtering** - Exclude pages tagged as category/index/stub
+3. **Content length signal** - Penalize pages with minimal content
+4. **Duplicate score detection** - Flag results with suspiciously identical scores
+
+The LLM re-ranking phase typically demotes these low-quality results, so this may not require immediate action.
+
+### Graph Search
+
+Graph search uses only core keywords (no LLM-generated synonyms) to avoid false matches like "author" → "author2000". This is intentional - vector search handles semantic similarity via embeddings.

+# 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"
+ }',

+
+### 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

+
+### B.4 Scheduler Client
+
+**New file:** `src/clients/scheduler_client.py`
+
+```python

+### B.5 Config Options
+
+**Modify:** `src/models/hybrid_rag.py`

+```python
+class HybridRAGConfig(BaseModel):
+    # ... existing fields ...
+
+    # Memory auto-save options
+    save_documents: bool = Field(default=False, description="Auto-upload PDFs to Paperless")

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

+        return [{"paperless_id": r.metadata.get("paperless_id"), ...} for r in results]
+
+    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

+└─────────────────┘
+```
+
+**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
+
+### Endpoints (Implemented)
+
+| Endpoint | Method | Purpose |
+|----------|--------|---------|
+| `/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/stats` | GET | Cache statistics |
+| `/volatile/scheduled` | GET | Records needing refresh |
+| `/volatile/namespaces` | GET | List available namespaces |
+| `/maintenance/cleanup/volatile` | POST | Purge expired records |
+
+### Namespaces
+
+| Namespace | Default TTL | Use Case |
+|-----------|-------------|----------|
+| weather | 30 min | Current conditions, forecasts |
+| news | 1 hour | Headlines, breaking news |
+| financial | 5 min | Stock prices, exchange rates |
+| transit | 5 min | Train/bus schedules, delays |
+| traffic | 10 min | Commute times, road conditions |
+| air_quality | 1 hour | Pollution, pollen counts |
+| sports | 1 min | Live scores, matches |
+| social | 10 min | Social notifications |
+| system | 1 min | Service health status |
+| context | 1 hour | Session state |
+| custom | 1 hour | User-defined data |
+

+
+## Phase 3: Document Storage (Research + Implementation)
+
+### Research Scope
+
+Evaluate FOSS self-hosted options for:
+- Git repository mirroring
+- PDF/document storage with metadata
+- Image/video blob storage
+- Full-text search capability
+
+**Constraints**:
+- Must be self-hosted, Docker-deployable
+- Performance is priority (can wrap complexity in API)
+- No cloud dependencies
+
+**Candidates to evaluate**:
+1. MinIO (S3-compatible object storage) + metadata in Neo4j
+2. Paperless-ngx (document management with OCR)
+3. SeaweedFS (distributed file system)
+4. Custom: filesystem + Neo4j metadata
+
+### Category Descriptors
+
+**Wiki page structure for document collections**:
+```markdown
+# FastAPI Documentation
+
+## Overview
+[LLM-generated summary from web search about FastAPI]
+
+## Collection Statistics
+- **Documents**: 342 files
+- **Last Sync**: 2025-12-24 03:30 UTC
+- **Source**: github.com/tiangolo/fastapi
+- **Coverage**: API reference, tutorials, deployment guides
+
+## What's Included
+[LLM summary of collection contents based on document analysis]
+
+## Related Topics
+- [[Python Web Frameworks]]
+- [[REST API Design]]
+```
+
+### Tasks
+
+#### 3.1 Storage Research
+**Deliverable**: Evaluation document comparing options
+
+#### 3.2 Storage Service Implementation
+**New file**: `src/services/document_store_service.py`
+(Details pending research results)
+
+#### 3.3 Category Descriptor Generation
+**File**: `src/services/consolidation_service.py`
+
+Add LLM-powered category descriptor generation:
+1. Web search for topic overview
+2. Analyze collection contents
+3. Generate/update wiki page with template
+
+---
+
+## Phase 4: LLM Tester Data Cleanup ✅
+
+### 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
+
+### Phase 2 (Volatile) ✅
+- `src/services/volatile_service.py` - Qdrant-based volatile cache
+- `src/routers/volatile.py` - Simplified endpoints
+- `src/models/volatile.py` - Namespaces and models
+- `src/models/hybrid_rag.py` - Volatile config options
+- `src/services/hybrid_rag_service.py` - Volatile integration
+- `src/clients/qdrant_client.py` - Expiry filter methods
+- `tests/test_volatile.py` - 37 tests
+
+### Phase 3 (Documents)
+- `docs/DOCUMENT_STORAGE_RESEARCH.md` - **NEW**
+- `src/services/document_store_service.py` - **NEW** (post-research)
+- `src/routers/documents.py` - **NEW** (post-research)
+
+### Phase 4 (Test Data Cleanup)
+- `src/routers/maintenance.py` - Add cleanup endpoint
+- `src/services/wiki_service.py` - Bulk delete by path pattern
+- `src/services/graph_service.py` - Pattern-based node deletion
+- `src/services/vector_service.py` - Pattern-based chunk deletion
+
+---
+
+## Resolved Design Decisions
+
+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
+
+---
+
+## Future Consideration: Dedicated API Integrations
+
+For volatile data where quality/consistency matters (weather, financial), consider:
+- OpenWeatherMap API for weather (daily refresh cycle)
+- Financial data API (Alpha Vantage, Yahoo Finance)
+- News APIs (NewsAPI, GDELT)
+- **NOS.nl** - Explicit source for Dutch news
+
+This would live in a new `src/clients/` module with:
+- `weather_client.py` - Daily refresh cycle
+- `financial_client.py`
+- `news_client.py` - Include NOS.nl scraper/API for Dutch coverage
+
+These provide structured, reliable data vs. SearXNG web scraping. Implementation deferred to later phase.
+
+---
+
+## Refresh Schedules
+
+**Note:** TTL should be longer than refresh interval to prevent data gaps.
+
+| Volatile Type | TTL | Refresh Cycle | Refresh Interval | Sources |
+|---------------|-----|---------------|------------------|---------|
+| Weather | 86400s (24hr) | Daily | Every 24hr | OpenWeatherMap |
+| Dutch News | 28800s (8hr) | 4x daily | Every 6hr | NOS.nl |
+| Global News | 28800s (8hr) | 4x daily | Every 6hr | NewsAPI, GDELT |
+| Financial | 600s (10min) | On-demand | N/A | Alpha Vantage |
+
+**TTL Logic:**
+- TTL = Refresh Interval × 1.5 (buffer for failed refreshes)
+- On-demand data gets shorter TTL since it's fetched when needed
