# Week 8 Day 0 - Coverage Baseline Analysis
**Generated:** 2025-10-29
**Overall Coverage:** 13.99% (13,873 statements, 11,540 missing)
**Target:** 80%+ (60%+ for each critical module)
______________________________________________________________________
## Executive Summary
**Critical Gap:** Only 13.99% of production code is covered by tests, despite having 978 unit tests (97.5% passing). This indicates that most tests focus on a narrow subset of functionality.
**Key Findings:**
- **27 modules with 0% coverage** (no tests at all)
- **Core modules under-tested:** server.py (50.8%), reflection_tools.py (44.7%), crackerjack_integration.py (26.4%)
- **Well-tested modules:** DI infrastructure (78.6% - 95.2%), settings.py (85.9%)
- **Estimated effort:** 200-300 new tests needed to reach 80%+ coverage

## Risk Assessment
### High Risk Items
1. **Test Isolation Issues** (4-8 failing tests)
- **Risk:** May be more complex than estimated
- **Mitigation:** Start Day 1, allocate extra time if needed
1. **Crackerjack Integration Complexity** (617 statements, 26% coverage)
- **Risk:** Complex parsing logic, many edge cases
- **Mitigation:** Focus on critical paths, mock extensively
1. **Time Overrun**
- **Risk:** 174-228 tests is substantial work
- **Mitigation:** Prioritize critical modules, defer Tier 4-5 if needed
### Medium Risk Items
4. **Mock Complexity** (DuckDB, ONNX, git, filesystem)
- **Risk:** Complex mocking may slow test development
- **Mitigation:** Reuse existing fixtures, document patterns
1. **Test Brittleness**
- **Risk:** Over-mocking leads to brittle tests
- **Mitigation:** Test behavior, not implementation
### Low Risk Items
6. **Coverage Plateau**
- **Risk:** May not reach 80% exactly
- **Mitigation:** 75-80% is acceptable, focus on critical paths
______________________________________________________________________
