### Priority 2: Security Documentation (Estimated: 1-2 hours)

#### A. Create SECURITY.md (HIGH PRIORITY ⚠️)

**Structure**:
```markdown
# Security Policy

## Supported Versions
## Reporting a Vulnerability
## Security Considerations
## Threat Model
## Safe Usage Guidelines
```

**Content**:
- [ ] Define supported versions for security updates
- [ ] Provide security issue reporting process
- [ ] Document threat model (file system access, YAML parsing)
- [ ] List security assumptions
- [ ] Provide safe usage guidelines

**Estimated**: 1 hour

#### B. Create Architecture Decision Records (HIGH PRIORITY ⚠️)

**Create**: `docs/adr/` directory

**ADRs to write**:
- [ ] ADR-001: Why YAML instead of JSON/SQLite
- [ ] ADR-002: Why TF-IDF for search
- [ ] ADR-003: Why DAG for task dependencies
- [ ] ADR-004: Why MCP protocol for Claude Code
- [ ] ADR-005: Why file-based storage

**Template**:
```markdown
# ADR-XXX: Title

**Status**: Accepted
**Date**: YYYY-MM-DD
**Context**: ...
**Decision**: ...
**Consequences**: ...
**Alternatives Considered**: ...
```

**Estimated**: 1 hour (template + 5 ADRs)

**Total Priority 2 Time**: ~2 hours

---

### Priority 3: KB Export Optimization (Estimated: 4 hours)

**From original plan - deferred from Day 6**

#### Goals:
- [ ] Profile current KB export performance
- [ ] Implement batch write optimization
- [ ] Add progress indicators for large exports
- [ ] Test with 100+ KB entries
- [ ] Benchmark improvements

**Estimated**: 4 hours

---

### Priority 4: Contributing Guide (Estimated: 1 hour)

#### Create CONTRIBUTING.md (MEDIUM PRIORITY)

**Structure**:
```markdown
# Contributing to Clauxton

## Development Workflow
## Pull Request Guidelines
## Code Review Checklist
## Testing Requirements
## Release Process
```

**Content**:
- [ ] Setup instructions for development
- [ ] Branch naming conventions
- [ ] Commit message guidelines
- [ ] PR template
- [ ] Code review checklist
- [ ] Testing requirements (coverage thresholds)
- [ ] Release process overview

**Estimated**: 1 hour

---

### Priority 5: Optional Enhancements (Low Priority)

#### A. Add Security Linting

**Install bandit**:
```bash
pip install bandit
```

**Add to pyproject.toml**:
```toml
[project.optional-dependencies]
dev = [
    # ... existing ...
    "bandit>=1.7",  # Security linter
]
```

**Add to CI**:
```yaml
- name: Security Lint
  run: bandit -r clauxton/ -ll
```

**Estimated**: 30 minutes

#### B. API Reference Documentation

**Setup mkdocs or Sphinx**:
- [ ] Install mkdocs-material
- [ ] Configure auto-generation from docstrings
- [ ] Deploy to GitHub Pages (optional)

**Estimated**: 2 hours

- ✅ Test coverage: 90%+ overall (currently 89%)
- ✅ Utils coverage: 80%+ (currently 55-67%) ← **CRITICAL**
- ✅ Security documentation complete (SECURITY.md)
- ✅ Architecture decisions documented (ADRs)
- ✅ Contributing guide available (CONTRIBUTING.md)
- ✅ All CI checks passing
- ✅ Security linting integrated

**Optional (Nice to Have)**:
- API reference documentation
- Performance optimizations (KB export)
- Complexity metrics
- Dead code analysis

## 📝 Notes

### Context for Next Session

1. **Test Performance**: Local full test suite is slow (120s+), but CI is fast (59s). Use modular testing locally as documented in TEST_PERFORMANCE.md.

2. **Coverage Gaps**: Critical gaps are in utils/ modules (backup_manager, yaml_utils, logger). These are security-sensitive components.

3. **Documentation Philosophy**: Following Clauxton's "Transparent Yet Controllable" principle - document security assumptions clearly.

4. **CI Status**: All checks passing, no blocking issues. Safe to proceed with new features.
