critical: Bulletproof Position Manager state persistence (Bug #87)
PROBLEM: Container restart caused Position Manager to lose tracking of runner system state, resulting in on-chain TP1 order closing entire position (100%) instead of partial close (60%). ROOT CAUSE: updateTradeState() had race condition in configSnapshot merge logic - nested Prisma query inside update caused non-atomic read-modify-write - positionManagerState was NULL in database despite saveTradeState() calls - Missing critical state fields: tp2Hit, trailingStopActive, peakPrice THE FIX (3-Layer Protection): 1. Atomic state persistence with verification - Separate read → merge → write → verify steps - Bulletproof verification after save (catches silent failures) - Persistent logger for save failures (investigation trail) 2. Complete state tracking - Added tp2Hit (runner system activation) - Added trailingStopActive (trailing stop recovery) - Added peakPrice (trailing stop calculations) - All MAE/MFE fields preserved 3. Bulletproof recovery on restart - initialize() restores ALL state from configSnapshot - Runner system can continue after TP1 partial close - Trailing stop resumes with correct peak price - No on-chain order conflicts FILES CHANGED: - lib/database/trades.ts (lines 66-90, 282-362) * UpdateTradeStateParams: Added tp2Hit, trailingStopActive, peakPrice * updateTradeState(): 4-step atomic save with verification * Persistent logging for save failures - lib/trading/position-manager.ts (lines 2233-2258) * saveTradeState(): Now saves ALL critical runner system state * Includes tp2Hit, trailingStopActive, peakPrice * Complete MAE/MFE tracking EXPECTED BEHAVIOR AFTER FIX: - Container restart: PM restores full state from database - TP1 partial close: 60% closed, 40% runner continues - TP2 activation: Runner exits with trailing stop - No on-chain order conflicts (PM controls partial closes) USER IMPACT: - No more missed runner profits due to restarts - Complete position tracking through container lifecycle - Bulletproof verification catches save failures early INCIDENT REFERENCE: - Trade ID: cmja0z6r00006t907qh24jfyk - Date: Dec 17, 2025 - Loss: ~$18.56 potential runner profit missed - User quote: "we have missed out here despite being a winner" See Bug #87 in Common Pitfalls for full incident details
