## 🔍 How to Find Specific Information

### Finding Information About a Feature
1. Go to [FEATURE_AUDIT.md](FEATURE_AUDIT.md)
2. Find feature in the "Features Stock Table"
3. Check columns:
   - Status: Implementation status
   - Notes/Gaps: Known issues
   - Tests: Test references

### Finding Tests for a Module
1. Go to [PROJECT_STRUCTURE_AUDIT.md](PROJECT_STRUCTURE_AUDIT.md)
2. Look at "New Test Directory Structure"
3. Find module subdirectory (e.g., `tests/ml/`)
4. Tests organized by functionality (e.g., `test_hyperparameter_tuning.py`)

### Finding Out About Blocking Gaps
1. Go to [FEATURE_AUDIT.md](FEATURE_AUDIT.md) → Section B or C
2. Find gap category (Protocol Paper or v1.0 Release)
3. Check Priority level (Critical or High)
4. See "Solution" and "Effort" estimates

### Understanding Remaining Work
1. Go to [CODEBASE_STATUS_SUMMARY.md](CODEBASE_STATUS_SUMMARY.md)
2. See "Blocking Gaps (Remaining)" section
3. Check "Recommendations" for prioritization
4. See "Timeline & Effort Estimates" for planning

## ⚠️ Remaining Blocking Gaps

### Critical for Protocol Paper
1. **Missing failure mode documentation** - All features
2. **Validation datasets missing** - 4 features
3. **VIP not implemented** - PLS/PLS-DA
4. **Test coverage insufficient** - 4 modules need >80%

### Critical for v1.0 Release
1. **Version compatibility not enforced** - Artifacts
2. **Calibration curve automation missing** - Harmonization
3. **Database backend missing** - Model registry
4. **Parallel execution not implemented** - Protocol engine

**See [FEATURE_AUDIT.md](FEATURE_AUDIT.md) sections A & B for details**

## 🚀 Next Steps

### Immediate (Next 2 weeks)
1. **Integrate gap closures** into core modules
2. **Update CONTRIBUTING.md** with test structure
3. **Review and approve** test reorganization

### Short-term (Weeks 3-4)
1. **Implement VIP** for PLS/PLS-DA
2. **Add version checking** to artifacts
3. **Expand test coverage** for critical modules

### Medium-term (Weeks 5-12)
1. **Curate validation datasets** for publication
2. **Implement database backend** for registry
3. **Add failure mode documentation** to all features
4. **Automate calibration curves** for harmonization

**See [CODEBASE_STATUS_SUMMARY.md](CODEBASE_STATUS_SUMMARY.md) "Recommendations" section**
