---
## 🔧 Phase 0: Database Fixes (COMPLETE)
### Issues Identified and Resolved
#### 1. ✅ Embedding System Path Issue
**Problem:** ONNX model couldn't be found at hardcoded path
```
Expected: ~/.cache/huggingface/hub/model.onnx
Actual: ~/.cache/huggingface/hub/models--Xenova--all-MiniLM-L6-v2/snapshots/.../onnx/model.onnx
```
**Solution:** Created symbolic link
```bash
ln -s ~/.cache/huggingface/hub/models--Xenova--all-MiniLM-L6-v2/snapshots/.../onnx/model.onnx \
~/.cache/huggingface/hub/model.onnx
```
**Result:** ✅ 384-dimensional embeddings working
#### 2. ✅ Missing Database Tables
**Problem:** Schema migration incomplete
**Missing:** `access_log_v2`, `code_graphs`
**Solution:** SQL ALTER TABLE statements
```sql
CREATE TABLE access_log_v2 (
reflection_id VARCHAR PRIMARY KEY,
access_timestamp TIMESTAMP,
access_count INTEGER DEFAULT 0
);
CREATE TABLE code_graphs (
id VARCHAR PRIMARY KEY,
repo_path TEXT NOT NULL,
commit_hash TEXT NOT NULL,
indexed_at TIMESTAMP NOT NULL,
nodes_count INTEGER NOT NULL,
graph_data JSON NOT NULL,
timestamp TIMESTAMP DEFAULT NOW(),
metadata JSON
);
```
**Result:** ✅ All tables created
#### 3. ✅ Missing Reflection Column
**Problem:** Reflections table missing `project` column
**Solution:** `ALTER TABLE reflections ADD COLUMN project VARCHAR;`
**Result:** ✅ Project tracking enabled
