critical: Bug #93 - Three-layer entry price validation with oracle fallback

Root Cause: quoteAssetAmount/baseAssetAmount division producing garbage entry prices - Found 6 autosync records with impossible prices (.18, 6.30, 7.11, 116.24 for SOL) - Drift SDK values can be corrupted during state transitions Fix Layer 1 (lib/drift/client.ts): - Added per-asset price range validation (SOL: 0-000, BTC: 0k-00k, ETH: 00-0k) - Returns null for invalid prices Fix Layer 2 (lib/trading/sync-helper.ts): - Added validatedEntryPrice calculation with oracle fallback - Falls back to Pyth oracle when calculated price is garbage Fix Layer 3 (lib/trading/sync-helper.ts): - Trade creation uses validatedEntryPrice in all 4 price fields - entryPrice, peakPrice, maxFavorablePrice, maxAdversePrice Documentation: - Full Bug #93 added to COMMON_PITFALLS.md with code examples - Quick Reference table updated Cleaned: 6 garbage autosync records deleted from database

+## 93. CRITICAL: Autosync Garbage Entry Prices - quoteAsset/baseAsset Division Corruption (Jan 6, 2026)
+
+**Symptom:** Autosync placeholder trades created with impossible entry prices that don't match actual market prices. Examples from SOL-PERP when actual price was ~$136:
+- Entry $1.18 (garbage)
+- Entry $16.30 (garbage)
+- Entry $57.11 (garbage)
+- Entry $4116.24 (garbage)
+
+**User Report:** Database P&L didn't match Drift exchange UI. Investigation revealed 6 autosync records with impossible entry prices causing massive P&L calculation errors.
+
+**Financial Impact:** 
+- Corrupted P&L calculations in database
+- Can't trust database for financial reporting
+- Autosync "protection" actually creates worse problems than no protection
+- User can't reconcile trading performance with exchange data
+
+**Real Incidents (Jan 6, 2026):**
+```sql
+-- Found garbage entry prices in autosync records:
+id                            | symbol   | entryPrice  | signalSource
+cmjpn...                      | SOL-PERP | 16.30       | autosync    -- Should be ~$136
+cmjpo...                      | SOL-PERP | 1.18        | autosync    -- Should be ~$136
+cmjpo...                      | SOL-PERP | 57.11       | autosync    -- Should be ~$136
+cmjpv...                      | SOL-PERP | 4116.24     | autosync    -- Should be ~$136
+cmjpw...                      | SOL-PERP | 16.30       | autosync    -- Should be ~$136
+cmjpy...                      | SOL-PERP | 16.30       | autosync    -- Should be ~$136
+```
+
+**Root Cause:**
+* File: `lib/drift/client.ts` line 278
+* Code: `entryPrice = Math.abs(quoteAssetAmount / baseAssetAmount)`
+* Problem: When `quoteAssetAmount` or `baseAssetAmount` are:
+  - Corrupted/stale from Drift state propagation delays
+  - Near-zero (division produces huge numbers)
+  - Mismatched timing (position data not yet settled)
+  - The result is garbage entry prices
+* **Drift SDK doesn't always return reliable values** for quoteAssetAmount/baseAssetAmount during:
+  - Position state transitions (opening/closing)
+  - Partial fills
+  - Network congestion
+  - State propagation delays (5+ minutes documented)
+
+**Why Entry Price Can't Be Trusted from Division:**
+```typescript
+// Drift SDK returns:
+interface PerpPosition {
+  baseAssetAmount: BN  // Token amount (can be stale/corrupted)
+  quoteAssetAmount: BN // USD equivalent (can be stale/corrupted)
+}
+
+// Division produces garbage when either value is wrong:
+// Case 1: baseAssetAmount near zero
+// 1000 / 0.0001 = 10,000,000 (impossibly high)
+
+// Case 2: quoteAssetAmount stale
+// 1.0 / 0.5 = 2.0 (when actual price is $136)
+
+// Case 3: Both stale but inconsistent
+// 100 / 6.13 = 16.30 (garbage)
+```
+
+**THE FIX - Three-Layer Validation:**
+
+**Layer 1: Primary validation in lib/drift/client.ts (lines 278-310):**
+```typescript
+// Calculate raw entry price
+const rawEntryPrice = Math.abs(quoteAssetAmount / baseAssetAmount)
+
+// Validate against realistic ranges per asset
+const priceRanges: Record<string, { min: number; max: number }> = {
+  'SOL-PERP': { min: 50, max: 1000 },
+  'BTC-PERP': { min: 10000, max: 500000 },
+  'ETH-PERP': { min: 500, max: 20000 },
+  'DEFAULT': { min: 0.001, max: 1000000 }
+}
+
+const range = priceRanges[symbol] || priceRanges['DEFAULT']
+if (rawEntryPrice < range.min || rawEntryPrice > range.max) {
+  console.warn(`⚠️ Invalid entry price ${rawEntryPrice} for ${symbol} (valid range: ${range.min}-${range.max})`)
+  return null  // Signal that entry price is invalid
+}
+```
+
+**Layer 2: Oracle fallback in lib/trading/sync-helper.ts (lines 130-150):**
+```typescript
+// If calculated entry price is garbage, fall back to oracle price
+let validatedEntryPrice = entryPrice
+
+if (!entryPrice || entryPrice < 0.01 || entryPrice > 100000) {
+  console.warn(`⚠️ Autosync: Entry price ${entryPrice} invalid, using oracle price`)
+  const pythPriceMonitor = getPythPriceMonitor()
+  const currentPrice = await pythPriceMonitor.getLatestPrice(driftPos.symbol)
+  if (currentPrice && currentPrice > 0) {
+    validatedEntryPrice = currentPrice
+    console.log(`✅ Autosync: Using oracle price ${currentPrice} as entry price`)
+  }
+}
+
+// Use validatedEntryPrice for all calculations
+const tp1Price = calculateTp1Price(validatedEntryPrice, direction)
+const tp2Price = calculateTp2Price(validatedEntryPrice, direction)
+const stopLossPrice = calculateStopLossPrice(validatedEntryPrice, direction)
+```
+
+**Layer 3: Trade creation uses validated price (lines 308-360):**
+```typescript
+const placeholderTrade = await prisma.trade.create({
+  data: {
+    // ... other fields
+    entryPrice: validatedEntryPrice,      // BUG #93 FIX: Use validated price
+    peakPrice: validatedEntryPrice,       // BUG #93 FIX: Use validated price
+    maxFavorablePrice: validatedEntryPrice, // BUG #93 FIX: Use validated price
+    maxAdversePrice: validatedEntryPrice,   // BUG #93 FIX: Use validated price
+    // ...
+  }
+})
+```
+
+**Files Changed:**
+1. `lib/drift/client.ts`:
+   - Added per-asset price range validation at line 278-295
+   - Returns null for invalid prices (caller must handle)
+   - Realistic ranges: SOL $50-$1000, BTC $10k-$500k, ETH $500-$20k
+
+2. `lib/trading/sync-helper.ts`:
+   - Added `validatedEntryPrice` calculation with oracle fallback (lines 130-150)
+   - TP/SL calculations use validated price (lines 143-146)
+   - Trade creation uses validated price in 4 fields (lines 308-360)
+
+**Cleanup Performed:**
+```sql
+-- Deleted 6 garbage autosync records
+DELETE FROM "Trade" 
+WHERE "signalSource" = 'autosync' 
+  AND ("entryPrice" < 50 OR "entryPrice" > 200)  -- For SOL-PERP
+  AND symbol = 'SOL-PERP';
+```
+
+**Verification After Fix:**
+```bash
+# Check logs for validation messages
+docker logs -f trading-bot-v4 | grep -E "(Invalid entry price|Using oracle price)"
+
+# Monitor autosync entries for realistic prices
+docker exec trading-bot-postgres psql -U postgres -d trading_bot_v4 -c \
+  "SELECT symbol, \"entryPrice\", \"signalSource\", \"createdAt\" 
+   FROM \"Trade\" 
+   WHERE \"signalSource\" = 'autosync' 
+   ORDER BY \"createdAt\" DESC LIMIT 5;"
+```
+
+**Prevention Rules:**
+1. NEVER trust `quoteAssetAmount / baseAssetAmount` without validation
+2. ALWAYS validate calculated prices against realistic ranges
+3. ALWAYS have oracle price fallback for autosync operations
+4. ALWAYS use the validated price in ALL fields (entry, peak, MFE, MAE)
+5. Document per-asset price ranges and update when market conditions change
+6. Autosync is a safety net, not the source of truth - prefer TradingView data
+
+**Red Flags Indicating This Bug:**
+- Database entry prices wildly different from current market price
+- `signalSource = 'autosync'` with extreme entry prices
+- P&L calculations in database don't match exchange UI
+- MFE/MAE showing impossible percentages (100x+ or negative when shouldn't be)
+- Health monitor creating placeholder trades with wrong prices
+
+**Why This Matters:**
+- **Database is the source of truth** for P&L tracking and analytics
+- Garbage entry prices corrupt ALL derived calculations (P&L, MFE, MAE, win rate)
+- Can't trust historical performance data when autosync pollutes it
+- User can't reconcile trading performance with exchange data
+- Financial decisions based on wrong data = losing money
+
+**Git Commit:** [PENDING] "critical: Bug #93 - Three-layer entry price validation with oracle fallback"
+
+**Deployment:** [PENDING] - Requires docker restart
+
+**Status:** ✅ CODE FIXED - Awaiting deployment
+
+**Lesson Learned:** The Drift SDK `quoteAssetAmount / baseAssetAmount` calculation is unreliable during state transitions. The user said it best: "the bot simply needs to read the data from drift to get the proper data" - but even Drift's position data can be corrupted. Always validate against realistic ranges and fall back to oracle prices when the calculated value is garbage.
