# External Review Summary - Task 5 (Updated)

## Status: FIXES APPLIED → Ready for Re-Review

### Codex Review Results (Iteration 2)
**Grade**: D (Needs Significant Work)
**Model**: GPT-5.2 Codex (OpenAI)

### All Critical Issues FIXED (Iteration 3)

✅ **API Spec Violation** - Implemented event-specific handlers (`onConnected()`, `onDisconnected()`, `onError()`)
✅ **Broadcast Bug** - Fixed `RecvError::Lagged` handling to continue receiving
✅ **Fatal Error Strategy** - Changed to `CalleeHandled` with proper error logging
✅ **tokio::spawn Safety** - Replaced with `napi::tokio::spawn`
✅ **Lifecycle Management** - EventListener Drop trait handles cleanup

### Validation Complete

- ✅ `cargo build -p x0x-nodejs` - Success
- ✅ `cargo clippy -p x0x-nodejs -- -D warnings` - Zero warnings
- ✅ `cargo fmt -p x0x-nodejs` - Formatted
- ✅ `cargo test -p x0x-nodejs` - All tests pass

### What Changed

**Before** (Generic callback):
```typescript
const listener = agent.on((event) => {
  if (event.event_type === 'connected') {
    console.log('Peer:', event.peer_id);
  }
});
```

**After** (Event-specific handlers - matches spec):
```typescript
const listener = agent.onConnected((event) => {
  console.log('Peer connected:', event.peer_id, event.address);
});

const errorListener = agent.onError((event) => {
  console.error('Error:', event.message);
});
```

### Next Steps

1. ✅ Codex review complete
2. ✅ Fixes applied
3. ⏳ Continue GSD review cycle (if other agents pending)
4. ⏳ Final consensus
5. ⏳ Mark Task 5 complete
