feat(library-desk): implement Phase 1 service clients and infrastructure

Implements comprehensive service client layer for Library Desk API to support
Librarian AI agent with multi-tenant knowledge management across Neo4j, Qdrant,
Wiki.js, SearXNG, and Ollama.

## Service Clients (src/clients/)
- Neo4j async client with connection pooling and user-scoped labels
- Qdrant vector store with collection-per-user multi-tenancy
- Wiki.js GraphQL API client for page/dossier management
- SearXNG client for web search integration
- Ollama client for text embeddings (nomic-embed-text)

## Core Infrastructure (src/core/)
- Multi-tenancy helpers for user namespace management
  - Wiki.js: path-based namespaces (/users/{user})
  - Neo4j: user-specific labels (User_{User}_Document)
  - Qdrant: collection per user (library_desk_{user})
- Dependency injection with FastAPI Depends and @lru_cache singletons
- Lifecycle management (startup/shutdown) for all service connections

## Background Jobs (src/jobs/)
- Redis-based job manager for long-running operations
- Job status tracking with 24-hour TTL
- Support for queued, processing, completed, failed states

## Configuration
- Updated config.py with Redis DB 4 for library-desk jobs
- Updated docker-compose.yml: REDIS_DB from 2 to 4
- Added pytest and pytest-asyncio to requirements.txt

## Testing
- Unit tests: 25/25 passed (multi-tenancy helpers)
- Integration tests: 12/12 passed (all services verified)
  - Neo4j connection and CRUD operations
  - Qdrant vector operations with 768-dim embeddings
  - Wiki.js GraphQL queries
  - SearXNG web search
  - Job Manager with Redis
  - Dependency injection lifecycle
- pytest.ini configuration with asyncio support

## Health Monitoring
- Real-time service health checks via /health endpoint
- Connection status for all 5 external services
- Graceful degradation for partial service availability

## Architecture
- Follows async/await pattern throughout
- Connection pooling for Neo4j (singleton driver)
- HTTP client lifecycle management (httpx)
- Multi-tenancy enforced at client layer
- Default user: jpmschweitzer

Files changed: 26 files
- 5 new service clients (~1500 lines)
- 2 core modules (~500 lines)
- 1 job manager (~350 lines)
- 3 test files with 37 test cases
- Updated main.py with lifecycle hooks

All services tested and operational. Ready for Phase 2 (routers/services).

# Librarian Integration Guide
**How The Scheduler (Librarian) interacts with Library Desk for documentation management**
## Overview
The Scheduler's documentation mirroring tasks feed content into The Library system via Library Desk API. This creates a knowledge graph and vector index of all documentation for semantic search and relationship discovery.
## Architecture Flow

}
```
## Scheduler Integration Workflow
### Phase 1: Mirror Documentation (Current)
```python
# This already exists in the Scheduler
async def mirror_documentation():
"""Mirror docs from external sources to Gitea"""
repos = [
"anthropics/anthropic-cookbook",
"anthropics/prompt-eng-interactive-tutorial",
# ... etc
]
for repo in repos:
# Clone/pull to /docs-mirror/{repo-name}
await git_sync(repo, f"/docs-mirror/{repo}")
```
### Phase 2: Index to Library (New)
```python
async def index_to_library():
"""Send mirrored docs to Library Desk for indexing"""
# Get list of documents in docs-mirror
docs_path = Path("/docs-mirror")
for repo_dir in docs_path.iterdir():
if not repo_dir.is_dir():
continue
# Find all markdown files
md_files = list(repo_dir.rglob("*.md"))
# Check what needs updating
update_check = await check_library_updates(md_files)
if update_check["updates_needed"]:
# Batch ingest updated documents
await batch_ingest_documents(
repository=repo_dir.name,
documents=update_check["updates_needed"]
)
# Wait for processing to complete
await wait_for_batch_completion(batch_id)
# Check for duplicates
await check_and_resolve_duplicates(repo_dir.name)
```
### Phase 3: Monitor & Maintain
```python
async def maintain_library_index():
"""Periodic maintenance of Library index"""
# Check for orphaned entries (deleted from source)
await cleanup_orphaned_documents()
# Update embeddings if model changed
await refresh_embeddings_if_needed()
# Generate relationship maps for new content
await discover_document_relationships()
```
## Scheduler Task Definition
**New Task: `library_sync`**
```yaml
Task Name: library_sync
Description: Sync mirrored documentation to Library for indexing and search
Schedule: Daily at 03:30 (after doc mirroring at 03:00)
Priority: 15 (user maintenance)
Service: library
Executor: scheduler.tasks.library_tasks.sync_library_index
Dependencies:
- docs_mirror (must complete first)
Configuration:
- LIBRARY_DESK_URL: http://library-desk:8089
- LIBRARY_API_KEY: ${LIBRARY_API_KEY}
- BATCH_SIZE: 50
- CHECK_UPDATES_ONLY: true
Outputs:
- Documents indexed
- Duplicates found
- Relationships created
```
## API Client Example
```python
# scheduler/src/clients/library_desk.py
import httpx
from typing import List, Dict, Any
from pathlib import Path
class LibraryDeskClient:
def __init__(self, base_url: str, api_key: str):
self.base_url = base_url
self.headers = {
"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json"
}
async def ingest_document(
self,
source: str,
repository: str,
path: str,
content: str,
metadata: Dict[str, Any]
) -> Dict[str, Any]:
"""Ingest a single document"""
async with httpx.AsyncClient() as client:
response = await client.post(
f"{self.base_url}/ingest/document",
headers=self.headers,
json={
"source": source,
"repository": repository,
"path": path,
"content": content,
"metadata": metadata
}
)
response.raise_for_status()
return response.json()
async def batch_ingest(
self,
source: str,
repository: str,
documents: List[Dict[str, Any]]
) -> Dict[str, Any]:
"""Ingest multiple documents"""
async with httpx.AsyncClient() as client:
response = await client.post(
f"{self.base_url}/ingest/batch",
headers=self.headers,
json={
"source": source,
"repository": repository,
"documents": documents
},
timeout=300.0 # 5 minutes for large batches
)
response.raise_for_status()
return response.json()
async def check_updates(
self,
documents: List[Dict[str, str]]
) -> Dict[str, Any]:
"""Check which documents need updating"""
async with httpx.AsyncClient() as client:
response = await client.post(
f"{self.base_url}/ingest/check-updates",
headers=self.headers,
json={"documents": documents}
)
response.raise_for_status()
return response.json()
async def get_repo_status(self, repository: str) -> Dict[str, Any]:
"""Get indexing status for a repository"""
async with httpx.AsyncClient() as client:
response = await client.get(
f"{self.base_url}/ingest/repo-status/{repository}",
headers=self.headers
)
response.raise_for_status()
return response.json()
```
## Typical Workflow Sequence
### Daily Documentation Sync (03:00-03:45)
1. **03:00** - Scheduler runs `docs_mirror` task
- Pulls latest from all configured repos
- Writes to `/docs-mirror/*`
2. **03:30** - Scheduler runs `library_sync` task
- Scans `/docs-mirror/` for changes
- Calls `POST /ingest/check-updates` with file hashes
- Gets list of updated/new documents
3. **03:31-03:40** - Batch ingestion
- Groups documents by repo
- Calls `POST /ingest/batch` for each repo
- Monitors `GET /ingest/status/{batch_id}`
4. **03:41-03:44** - Post-processing
- Calls `POST /deduplicate/check` for new docs
- Reviews duplicate suggestions
- Logs statistics to Scheduler database
5. **03:45** - Completion
- Scheduler marks task complete
- Sends summary to logs
- Updates next run time
## Error Handling
### Retry Strategy
```python
async def ingest_with_retry(document: Dict, max_retries: int = 3):
"""Ingest with exponential backoff"""
for attempt in range(max_retries):
try:
result = await library_client.ingest_document(**document)
return result
except httpx.TimeoutException:
if attempt < max_retries - 1:
await asyncio.sleep(2 ** attempt) # 1s, 2s, 4s
else:
# Log failure and continue
logger.error(f"Failed to ingest {document['path']} after {max_retries} attempts")
return None
```
### Graceful Degradation
- If Library Desk is down, queue documents for later ingestion
- Store failed ingestions in Scheduler database
- Retry failed ingestions on next run
## Metrics to Track
The Scheduler should track:
- Documents mirrored vs. documents indexed
- Average ingestion time per document
- Deduplication rate
- Failed ingestions
- Library Desk response times
These can be displayed in the Scheduler UI dashboard.
## Environment Variables
Add to Scheduler's environment:
```bash
# Library Integration
LIBRARY_DESK_URL=http://library-desk:8089
LIBRARY_API_KEY=${LIBRARY_API_KEY}
LIBRARY_BATCH_SIZE=50
LIBRARY_SYNC_ENABLED=true
```
## Next Steps
1. Implement ingestion endpoints in Library Desk
2. Add LibraryDeskClient to Scheduler
3. Create `library_sync` task in Scheduler
4. Test with small batch of documents
5. Monitor and tune performance
6. Expand to full documentation corpus
## Benefits
- **Automatic Knowledge Base**: All mirrored docs automatically indexed
- **Semantic Search**: Find docs by meaning, not just keywords
- **Relationship Discovery**: Understand connections between docs
- **Deduplication**: Identify overlapping content across repos
- **HybridRAG Ready**: Knowledge graph + vectors enable advanced AI queries

## Scheduler Integration
See [LIBRARIAN_INTEGRATION.md](./LIBRARIAN_INTEGRATION.md) for details on how The Scheduler (Librarian) integrates with Library Desk for automated documentation indexing.
**Key Workflow:**
1. Scheduler mirrors docs to Gitea (daily 03:00)
2. Scheduler syncs to Library Desk (daily 03:30)
3. Library Desk ingests, chunks, embeds, and indexes
4. Content becomes searchable via HybridRAG
