CRITICAL: Position Manager stops monitoring randomly
User had to manually close SOL-PERP position after PM stopped at 23:21.
Implemented double-checking system to detect when positions marked
closed in DB are still open on Drift (and vice versa):
1. DriftStateVerifier service (lib/monitoring/drift-state-verifier.ts)
- Runs every 10 minutes automatically
- Checks closed trades (24h) vs actual Drift positions
- Retries close if mismatch found
- Sends Telegram alerts
2. Manual verification API (app/api/monitoring/verify-drift-state)
- POST: Force immediate verification check
- GET: Service status
3. Integrated into startup (lib/startup/init-position-manager.ts)
- Auto-starts on container boot
- First check after 2min, then every 10min
STATUS: Build failing due to TypeScript compilation timeout
Need to fix and deploy, then investigate WHY Position Manager stops.
This addresses symptom (stuck positions) but not root cause (PM stopping).
