### Tasks Pending (4/11)

#### Task 7: Integrate Network with Agent 
- **Status**: NOT STARTED - Ready to begin

- **Dependencies**: Tasks 1-6 (all complete)
- **Estimated Lines**: ~60
- **Subtasks**:
  1. Implement Agent::join_network() to initialize NetworkNode
  2. Implement Agent::subscribe(topic) to create pub/sub subscriptions
  3. Implement Agent::publish(topic, payload) to broadcast messages
  4. Wire NetworkNode events to Subscription receivers

#### Task 8: Add Bootstrap Support
- **Status**: NOT STARTED
- **Spec**: Implement bootstrap node discovery and connection
- **Dependencies**: Task 7 (Agent integration)
- **Estimated Lines**: ~40

#### Task 9: Write Network Tests
- **Status**: NOT STARTED
- **Spec**: Comprehensive integration tests for network operations
- **Dependencies**: Tasks 1-8
- **Estimated Lines**: ~80

#### Task 10: Integration Test - Agent Network Lifecycle
- **Status**: NOT STARTED
- **Spec**: End-to-end agent lifecycle with network operations
- **File**: tests/network_integration.rs
- **Estimated Lines**: ~80

#### Task 11: Documentation Pass
- **Status**: NOT STARTED
- **Spec**: cargo doc with zero warnings
- **Files**: src/network/*.rs, README.md
- **Estimated Lines**: ~30

## Quality Metrics

**Current (Task 6 Complete)**:
- Tests Passing: 244/244 (100%)
- Compilation Warnings: 0
- Compilation Errors: 0
- Clippy Violations: 0
- Unsafe Code: 0
- Code Coverage: Good (network layer fully covered)
- Documentation: Comprehensive on Tasks 1-6

## Architecture Integration

```
Task 1-3:  Configuration & Types
    ↓
Task 4-5:  Network Transport (COMPLETE)
    ↓
Task 6:    Message Serialization (COMPLETE)
    ↓
Task 7:    Agent Integration (NEXT)
    ↓
Task 8-9:  Bootstrap & Testing
    ↓
Task 10:   Integration Testing
    ↓
Task 11:   Documentation
```

## Critical Path Analysis

**Blocking Dependency**: Task 7 is critical
- Unblocks: Tasks 8-10
- Required for: Phase 1.2 completion
- Complexity: Moderate-High (coordination across 3 modules)

**Estimated Time Remaining** (assuming continued autonomous execution):
- Task 7: ~2-3 hours (design + implementation + testing)
- Tasks 8-9: ~2-3 hours (focused integration)
- Task 10-11: ~1-2 hours (testing + docs)
- **Total**: ~5-8 hours to Phase 1.2 completion

## Next Steps

1. **Immediate**: Implement Task 7 (Agent integration)
   - Requires careful API design for subscribe/publish
   - Must handle Tokio async/broadcast channels
   - Need to coordinate with NetworkNode lifecycle

2. **Short-term**: Complete Tasks 8-11
   - Bootstrap selection and connection retry logic
   - Property-based testing with proptest
   - Integration test harness

3. **Phase Completion**: Verify all 11 tasks complete
   - Ensure zero warnings/errors
   - Full test coverage
   - Documentation generation

## Known Issues / Considerations

1. **Phase 3.1 QUIC Binding**: Previous attempts showed QUIC transport not binding. This is likely due to incomplete Agent::join_network() implementation - once Task 7 completes, should re-test Phase 3.1.

2. **Memory Management**: Network uses Arc<RwLock<>> pattern - should verify no memory leaks under sustained network operations.

3. **Event Broadcasting**: Subscription implementation uses placeholder - Task 7 must properly wire NetworkNode events to subscribers.
