| `reflection_tags` | 0 | Empty |
| `project_groups` | 0 | Empty |
| `project_dependencies` | 0 | Empty |
| `session_links` | 0 | Empty |
| `access_log_v2` | ❌ | Missing table |
| `code_graphs` | ❌ | Missing table |
**Data Quality:**
- ✅ **100% embedding coverage** on reflections (35/35 have embeddings)
- ❌ **No recent activity** (0 new in last 7 days)
- ⚠️ **Schema issue:** Missing `project` column in reflections table
- ✅ **No orphaned records** (data integrity OK)
**Issues Found:**
1. **Missing tables:** `access_log_v2` and `code_graphs` not created
2. **Schema drift:** `project` column missing from reflections table
3. **No conversations:** Only reflections stored, no conversation history

**Status:** ✅ Operational (58.0 MB)
| Table | Rows | Status |
|-------|------|--------|
| `kg_entities` | 597 | ✅ Active |
| `kg_relationships` | 19 | ✅ Active |
| `__duckpgq_internal` | 2 | System |
**Issues Found:**
1. **Missing column:** `embedding` column not found in `kg_entities` table
2. **Low connectivity:** 19 relationships for 597 entities (avg: 0.03 per entity)

### 3. Crackerjack Integration Database (`~/.claude/data/crackerjack_integration.db`)
**Status:** ✅ **Highly Active** (6.6 MB)
| Table | Rows | Status |
|-------|------|--------|
| `crackerjack_results` | 6,690 | ✅ Very Active |
| `quality_metrics_history` | 7,381 | ✅ Very Active |
| `progress_snapshots` | 4,909 | ✅ Very Active |

### 4. Interruption Manager Database (`~/.claude/data/interruption_manager.db`)
**Status:** ⚠️ **Unused** (48 KB)
| Table | Rows | Status |
|-------|------|--------|
| `context_snapshots` | 0 | Empty |
| `interruption_events` | 0 | Empty |
| `session_contexts` | 0 | Empty |
**Assessment:** Feature not actively used or not enabled.

### 5. Shared Analytics Database (`~/.claude/data/shared_analytics.duckdb`)
**Status:** ⚠️ **Empty** (12 KB)
- **No tables found**
- Database file exists but not initialized

## Embedding System Status
**Status:** ❌ **Configuration Issue Detected**
```
ONNX Runtime: Available ✅
Model Loading: Failed ❌
Error: File not found at /Users/les/.cache/huggingface/hub/model.onnx
```
**Root Cause:** Model path mismatch
**Actual Model Location:**
```
/Users/les/.cache/huggingface/hub/models--Xenova--all-MiniLM-L6-v2/snapshots/751bff37182d3f1213fa05d7196b954e230abad9/onnx/model.onnx
```
**Expected Location (by code):**
```
/Users/les/.cache/huggingface/hub/model.onnx
```
**Note:** Despite the error, embeddings were successfully generated for all 35 reflections (100% coverage), indicating the system may be using an alternative embedding method or was previously working.
---
## Recommendations
### Priority 1: Fix Embedding System
**Issue:** ONNX model path hardcoded incorrectly
**Solution Options:**
1. **Option A:** Create symbolic link
```bash
ln -s ~/.cache/huggingface/hub/models--Xenova--all-MiniLM-L6-v2/snapshots/751bff37182d3f1213fa05d7196b954e230abad9/onnx/model.onnx \
~/.cache/huggingface/hub/model.onnx
```
2. **Option B:** Update embedding system to auto-discover model path
- Modify `session_buddy/reflection/embeddings.py` to search HuggingFace cache
- Use `transformers` library's built-in model discovery
3. **Option C:** Use transformers-based embeddings as fallback
- Already attempted in code (line 108-109)
- Requires PyTorch (currently not installed)
### Priority 2: Complete Database Schema Migration
**Issue:** Missing tables from recent schema updates
**Action Required:**
```python
# Run schema initialization to create missing tables
from session_buddy.reflection.database import ReflectionDatabase
import asyncio
async def migrate():
db = ReflectionDatabase()
await db.initialize()
# This should create access_log_v2 and code_graphs tables
asyncio.run(migrate())
```
### Priority 3: Fix Reflection Schema
**Issue:** Missing `project` column in reflections table
**SQL Fix:**
```sql
ALTER TABLE reflections ADD COLUMN project VARCHAR;
```
### Priority 4: Populate Conversation History
**Issue:** No conversations stored (0 rows)
**Recommendation:**
- Verify conversation storage is enabled
- Check if `/checkpoint` command is being used
- Review auto-store configuration
