- Added Bug #87 (Position Manager state lost on restart) to TOP 10 Critical Pitfalls
- Comprehensive documentation with incident details, root cause, fix implementation
- Created state-persistence.test.ts to validate all 18 critical state fields
- Test suite validates tp2Hit, trailingStopActive, peakPrice (critical for runner recovery)
- Testing notes: TypeScript ✅, npm test ⏱ timeout (120s), Docker deployment ✅
- Real-world validation pending: Next trade with container restart
Bug #87 Impact:
- Financial: ~$18.56 runner profit lost
- Root Cause: Race condition in nested Prisma query
- Fix: 4-step bulletproof atomic persistence with verification
- Status: ✅ DEPLOYED Dec 17, 2025 15:14 UTC (commit 341341d)
