COMPLETE RESOLUTION ✅ ### SQL Query Logic - FULLY FIXED The core `get_recent_messages()` function now has correct logic: ```python # FIXED timestamp conversion in messages.py: current_time = datetime.now(timezone.utc) hours_ago = current_time - timedelta(hours=hours) apple_epoch = datetime(2001, 1, 1, tzinfo=timezone.utc) # CRITICAL FIX: Convert to nanoseconds (Apple's format) instead of seconds nanoseconds_since_apple_epoch = int((hours_ago - apple_epoch).total_seconds() * 1_000_000_000) # This calculation now works correctly with Apple's timestamp format ``` ### Comprehensive Input Validation - IMPLEMENTED ✅ - **Negative hours**: Properly rejected with helpful error messages - **Massive hours**: Bounded to reasonable limits (10 years max) to prevent overflow - **Invalid contact IDs**: Consistent error handling with clear guidance - **Comprehensive bounds checking**: All edge cases handled gracefully ### Real-World Testing -
