feat: add test data cleanup endpoint

Add POST /maintenance/cleanup/test-data endpoint to purge LLM test data
from wiki, graph, and vectors. Security-restricted to test user namespace
only (users/llm-tester/*, users/llm_tester/*).

- Supports dry_run=true (default) to preview before deleting
- Cleans vectors, graph nodes, and wiki pages
- Scheduler task configured for weekly cleanup (Sunday 3:00 AM)

-### 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"
-    data: dict                         # Actual content
-    source: Optional[str]              # Origin API/service
-    created_at: datetime
-    updated_at: datetime
-    ttl: int                           # Seconds until expiration
-    refresh_schedule: Optional[str]    # Cron expression, if repeating
-    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`
-
-```python
-def get_biographer_qdrant() -> QdrantClientWrapper:
-    """Direct access to tatlock's Biographer collection."""
-    # Configure to connect to tatlock's Qdrant
-```
-
-#### 2.5 Scheduler-Side Configuration
-Document required scheduler tasks:
-```json
-{
-  "task_name": "volatile_refresh",
-  "schedule": "*/15 * * * *",
-  "endpoint": "GET /volatile/scheduled",
-  "follow_up": "For each record, call refresh endpoint with record.refresh_schedule"
-}
-```
+| 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 |

-## 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)

+    - 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"
+}
+```
+

 ## 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
