+Split `AnalyzeProject.ts` (614 lines) into focused pipeline components.
+
+**Problem:**
+- God Use-Case with 614 lines
+- Mixing: file scanning, parsing, detection, aggregation
+- Hard to test and modify individual steps
+
+**Solution:**
+```

+├── pipeline/
+│   ├── FileCollectionStep.ts  # File scanning
+│   ├── ParsingStep.ts         # AST + dependency graph
+│   ├── DetectionPipeline.ts   # All 7 detectors
+│   └── ResultAggregator.ts    # Build response DTO
+```
+
+**Deliverables:**
+- [ ] Extract 4 pipeline components
+- [ ] Reduce `AnalyzeProject.ts` to ~100 lines
+- [ ] All tests pass, no breaking changes
+- [ ] Publish to npm

+### Version 0.7.6 - Refactor CLI Module 🔧
+
+**Priority:** MEDIUM

+**Solution:**
+```
+cli/
+├── index.ts                  # Commands only (~100 lines)
+├── formatters/
+│   ├── OutputFormatter.ts    # Violation formatting
+│   └── StatisticsFormatter.ts
+├── groupers/
+│   └── ViolationGrouper.ts   # Sorting & grouping
+```
+
+**Deliverables:**
+- [ ] Extract formatters and groupers
+- [ ] Reduce `cli/index.ts` to ~100-150 lines

+|------|----------|
+| SourceFile.ts | 46% |
+| ProjectPath.ts | 50% |
+| ValueObject.ts | 25% |
+| RepositoryViolation.ts | 58% |
+
+**Deliverables:**
+- [ ] SourceFile.ts → 80%+
