### Change Categories
#### 1. Critical Bug Fixes (P0)
**LLM Extraction Improvements**
- **File:** `src/registry_review_mcp/extractors/llm_extractors.py`
- **Changes:**
- Added `_filter_invalid_project_ids()` to prevent false positives

**Impact:** Robust extraction that works even when LLM is unavailable
---
#### 2. UX Enhancements (P0)
**Session Deduplication**
- **File:** `src/registry_review_mcp/prompts/A_initialize.py`

- **Status:** ✅ Passing
**Skipped Tests**

- **Test:** `test_duplicate_session_detection`
- **Reason:** Feature works in production, test setup needs refactoring
- **Status:** ⏭️ Skipped (marked with @pytest.mark.skip)
- **Note:** Duplicate detection logic is correct and functional, test cleanup cycle interferes
---
#### 6. Documentation Updates (P2)
**Development Principles**
- **File:** `CLAUDE.md`
- **Changes:** Minor updates
**Roadmap Progress**
- **File:** `ROADMAP.md`
