#### 3. Add Bandit to CI/CD (Priority: MEDIUM)
**Estimated Time**: 30 minutes

**Purpose**: Automated security scanning in every pull request

**Tasks**:

4. Test workflow with sample PR

**Implementation**:

`.github/workflows/ci.yml`:
```yaml
security:
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@v4
    - uses: actions/setup-python@v4
      with:
        python-version: '3.11'
    - name: Install dependencies
      run: pip install bandit
    - name: Run security checks
      run: bandit -r clauxton -f json -o bandit-report.json
    - name: Upload report
      uses: actions/upload-artifact@v4
      with:
        name: bandit-report

```

---

#### 4. Add Utils Module Tests (Priority: MEDIUM)
**Estimated Time**: 1-1.5 hours

**Purpose**: Increase overall coverage from 91% to 93%+

**Gaps Identified** (from Session 11 Gap Analysis):

**`clauxton/utils/yaml_utils.py` (80% → 95% target)**:
- Missing: Error recovery after failed atomic write
- Missing: File permission edge cases (readonly directories)
- Missing: Large file handling (>10MB YAML)
- Missing: Concurrent write scenarios

**`clauxton/utils/file_utils.py` (85% → 95% target)**:
- Missing: Symlink permission handling
- Missing: Nested directory creation edge cases
- Missing: Path traversal attack scenarios

**New Tests to Add** (~20-25 tests):
1. **yaml_utils.py** (10-12 tests):
   - `test_atomic_write_partial_failure` - Disk full during write
   - `test_write_to_readonly_directory` - Permission denied scenario
   - `test_large_yaml_file_handling` - 10MB+ YAML file
   - `test_concurrent_write_detection` - Multiple processes
   - `test_backup_on_write_failure` - Backup preserved on error
   - `test_unicode_edge_cases` - Emoji, CJK characters, RTL text
   - `test_yaml_bomb_protection` - Malicious YAML structures
   - `test_deep_nesting` - Deeply nested YAML (100+ levels)
   - `test_corrupted_yaml_recovery` - Malformed YAML handling
   - `test_empty_file_handling` - Empty YAML file edge cases

2. **file_utils.py** (10-12 tests):
   - `test_symlink_permission_validation` - Symlink to readonly file
   - `test_nested_directory_creation` - 10+ level nesting
   - `test_path_traversal_attack` - ../../../etc/passwd attempts
   - `test_special_characters_in_paths` - Unicode, spaces, quotes
   - `test_long_path_handling` - Paths >256 characters
   - `test_filesystem_race_conditions` - Directory deleted during operation
   - `test_case_sensitive_filesystems` - macOS vs Linux differences
   - `test_windows_path_compatibility` - Backslash handling
   - `test_hidden_directory_creation` - .hidden directories
   - `test_permission_inheritance` - Subdirectory permissions

**Expected Outcome**:
- Utils coverage: 80-85% → 95%+
- Overall coverage: 91% → 93%+
- Security: Additional protection against edge cases

   - Risk: Takes longer than estimated
   - Mitigation: Start with essential content, expand later
   - Fallback: Release with partial docs, complete in v0.10.2

2. **Bandit Integration**
   - Risk: False positives in CI
   - Mitigation: Configure .bandit to exclude test files
   - Fallback: Make bandit job non-blocking initially

3. **Test Coverage**
   - Risk: Hard-to-test edge cases
   - Mitigation: Focus on high-impact scenarios first
   - Fallback: Document known gaps for v0.10.2
