+## 🔧 Fixes Applied During Testing
+
+### 1. JWT Strategy Fix
+**Problem:** JWT returned `userId` but controllers expected `sub`
+**Solution:** Updated JWT strategy to return `sub`
+**Files Modified:**
+- `src/auth/jwt.strategy.ts`
+- `src/adoption/adoption.controller.ts`
+
+### 2. Search Test Update
+**Problem:** Search test didn't include description field
+**Solution:** Updated test to expect description in OR clause
+**Files Modified:**
+- `src/pets/pets.service.spec.ts`
+
+---
