**Current Status**: 72 SATD violations in 24 files
**Target**: Reduce to <30 hours of technical debt (from 42.5 hours)

## Analysis Overview

**Violation Count by Severity**:
- **High**: 15 (20.8%)
- **Medium**: 2 (2.8%)
- **Low**: 55 (76.4%)
- **Total**: 72 violations

**Violation Types**:
- **Requirement**: 48 (66.7%) - Missing features/implementations
- **Defect**: 15 (20.8%) - Known bugs/issues
- **Design**: 8 (11.1%) - Design problems
- **Performance**: 1 (1.4%) - Performance issues

## Top Hotspots

| Rank | File | Count | Pattern | Priority |
|------|------|-------|---------|----------|
| 1 | server/src/services/context.rs | 28 | Language-specific TODOs | HIGH |
| 2 | server/src/cli/language_analyzer.rs | 10 | Bug fixes (PMAT-BUG-*) | HIGH |
| 3 | server/src/cli/handlers/unified_context_builder.rs | 5 | Analysis feature TODOs | MEDIUM |
| 4 | server/src/services/mutation/executor.rs | 4 | Mutation test improvements | MEDIUM |
| 5 | server/src/quality/efficiency_enhanced.rs | 3 | Quote macro issues | LOW |
| 6 | server/src/services/mutation/distributed.rs | 2 | Distributed execution | LOW |
| 7 | server/src/services/deep_wasm/service.rs | 2 | WebAssembly features | LOW |
| 8 | server/src/services/deep_context.rs | 2 | Context improvements | MEDIUM |

## Prioritization Matrix

| Priority | File | Count | Effort | Impact | Action |
|----------|------|-------|--------|--------|--------|
| P1 | language_analyzer.rs | 10 | Medium | High | Fix language detection bugs |
| P1 | context.rs | 10 | Low | Medium | Implement top language analyzers |
| P2 | context.rs | 18 | Medium | Medium | Implement remaining language analyzers |
| P2 | unified_context_builder.rs | 5 | Medium | Medium | Implement analysis hooks |
| P2 | mutation/executor.rs | 4 | Medium | Medium | Implement mutation improvements |
| P3 | efficiency_enhanced.rs | 3 | High | Medium | Fix quote macro usage |
| P3 | deep_wasm/service.rs | 2 | Medium | Low | Implement WASM features |
| P3 | deep_context.rs | 2 | Medium | Low | Context improvements |
| P4 | Various (12 files) | 18 | Various | Low | Address as time permits |

## Remediation Plan

### Phase 1: Critical Bug Fixes (P1)
- **language_analyzer.rs** (10 violations): Fix high-severity bug fixes (PMAT-BUG-* series)
  - These address critical language detection issues
  - Fixes should be compatible with existing tests

### Phase 2: High-Value TODOs (P1-P2)
- **context.rs** (Top 10 violations): Implement high-priority language analyzers
  - C, C++, JavaScript, TypeScript, Python
  - Test with corresponding language fixture files
- **unified_context_builder.rs** (5 violations): Implement analysis feature hooks
  - Big-O, Entropy, Provability, Graph metrics, Dead code

### Phase 3: Medium-Impact Issues (P2-P3)
- **context.rs** (Remaining 18 violations): Implement additional language analyzers
  - Ruby, Go, Kotlin, PHP, Java, etc.
- **mutation/executor.rs** (4 violations): Improve mutation test executors
  - Focus on distributed execution and parallel processing

### Phase 4: Complex Refactoring (P3)
- **efficiency_enhanced.rs** (3 violations): Fix quote macro usage
  - This requires deeper understanding of the macro system
  - More complex than other TODOs

## Expected Impact

Addressing these violations will:
1. **Fix Critical Bugs**: Language analyzer fixes impact core functionality
2. **Expand Language Support**: Adding missing language analyzers improves coverage
3. **Enhance Analysis Features**: Implementation of missing analysis features
4. **Improve Code Quality**: Refactor complex areas with technical debt

## Implementation Priority

1. **P1 Issues** (20 violations): These will provide the highest impact
2. **P2 Issues** (27 violations): High to medium impact with reasonable effort
3. **P3 Issues** (7 violations): More complex issues with medium impact
4. **P4 Issues** (18 violations): Address as time permits

## Next Steps

1. Begin with implementing fixes for language_analyzer.rs (PMAT-BUG series)
2. Implement top 5-10 language analyzers in context.rs
3. Add analysis feature hooks in unified_context_builder.rs
4. Measure impact and adjust plan as needed

## Notes

For consistent resolution of language analyzer TODOs, we should:
1. Create a consistent pattern for language analyzer implementation
2. Use the existing analyzers as templates
3. Add appropriate tests for each implemented analyzer
4. Document the analysis capabilities for each language
