## 🎯 What Was Accomplished

### Tasks 1-6 ✅ All Complete

1. ✅ **Review AS_PATH implementation**
   - Analyzed `aspath.py` (246 lines)
   - Identified 4 segment types, ASN2/ASN4 handling

2. ✅ **Create AS_PATH tests**
   - 21 comprehensive tests
   - All segment types, error cases, packing/unpacking

3. ✅ **Review attributes framework**
   - Analyzed `attributes.py` (514 lines)
   - Identified parsing flow, error handling, RFC 7606 compliance

4. ✅ **Create attributes framework tests**
   - 24 comprehensive tests
   - Flags, lengths, duplicates, errors, edge cases

5. ✅ **Run all tests and verify**
   - 103/103 tests passing
   - No regressions
   - New tests integrate cleanly

6. ✅ **Commit and push**
   - 2 commits created
   - All changes pushed to remote
   - Documentation complete

## 📝 Important Notes

### Test Execution
Always use `PYTHONPATH=src` when running tests:
```bash
PYTHONPATH=src python -m pytest tests/ -v
```

### Dependencies Required
```bash
pip install hypothesis pytest-cov pytest-xdist pytest-timeout pytest-benchmark
```

### Logger Mocking Pattern
Tests use this pattern to avoid initialization issues:
```python
@pytest.fixture(autouse=True)
def mock_logger():
    with patch('module.logfunc') as mock_logfunc, \
         patch('module.log') as mock_log:
        mock_logfunc.debug = Mock()
        mock_log.debug = Mock()
        yield
```
