- ✅ Test suite: Extremely fast execution

---

## Issues & Recommendations

### Issues Found
**None** - All tests passed successfully.

### Observations

1. **Skipped Configuration Test**
   - Test: `test_load_context_management_config`
   - Reason: Checks for configuration in `~/.claude-mpm/configuration.yaml` (user home)
   - Status: OPTIONAL - Project has local config at `./.claude-mpm/configuration.yaml`
   - Impact: None - Local configuration works perfectly
   - Recommendation: Update test to check local config path first

2. **File Permission Difference**
   - Markdown: 644 (world-readable)
   - JSON: 600 (owner-only)
   - Status: INTENTIONAL - JSON contains metadata, markdown is for sharing
   - Impact: None
   - Recommendation: Document this design choice

### Recommendations for Future Enhancements

1. **Token Estimation Before Generation**
   - Consider adding pre-generation token estimation
   - Warn if resume log might exceed 10k token budget
   - Priority: LOW (current implementation handles large states well)

2. **Compression for Old Logs**
   - Consider gzip compression for archived logs
   - Could save storage space for long-running projects
   - Priority: LOW (current cleanup strategy sufficient)

3. **Resume Log Templates**
   - Allow custom templates for different use cases
   - Engineering vs QA vs PM templates
   - Priority: MEDIUM (would improve UX)

4. **Metrics Dashboard**
   - Track resume log usage statistics over time
   - Show token usage trends across sessions
   - Priority: LOW (nice-to-have)

5. **Test Suite Addition**
   - Add test for concurrent session managers (multi-threading)
   - Test actual file system errors (disk full, permission denied)
   - Priority: MEDIUM (current tests sufficient for v1)
