# Core Memory Refactor - Completed

> **⚠️ Historical document — Phase 1 refactor closeout.**
> References pre-Phase-9 paths (`openclaw_integration.py`,
> `integrations/openclaw_agent_end_bridge.py`, etc.) that no longer exist.
> Current canonical paths: `core_memory/integrations/openclaw/*.py`.
> Retained for history; will be archived in Phase 10.

## ✅ All Items Complete

### Phase 1 Quick Wins
- [x] Fix `session_surface.py` logger bug - Added logger import
- [x] Label legacy files in docstrings - Marked deprecated in code
- [x] Reorganize CLI command families - Added command families to docstring
- [x] Document canonical architecture centers - Created ARCHITECTURE.md

### Phase 2: Extraction from store.py (Meat)
- [x] `retrieval/query_norm.py` - Added `_tokenize`, `_is_memory_intent`, `_expand_query_tokens`
- [x] `retrieval/failure_patterns.py` - New file with failure signature detection
- [x] `retrieval/context_recall.py` - New file with context-aware retrieval
- [x] `hygiene.py` - Added `_redact_text`, `sanitize_bead_content`, `extract_constraints`
- [x] `policy/promotion.py` - New file with scoring, threshold, candidate evaluation
- [x] **store.py legacy methods now thin delegators** - Compatibility maintained

### Phase 3: Rolling Surface Clarity
- [x] Already properly structured (rolling_record_store.py is authority)

### Phase 4: Integration Overlap Cleanup
- [x] Canonical OpenClaw surface: `integrations/openclaw_agent_end_bridge.py`
- [x] Deprecated: `openclaw_integration.py`

### Phase 5: Readability Splits
- [x] `graph.py` → `graph_structural.py`, `graph_traversal.py`, `graph_semantic.py`
- [x] `retrieval/rerank.py` - Added note (not split - manageable size)

### Optional: Promotion Logic
- [x] `policy/promotion.py` - New file with scoring, threshold, candidate evaluation
