# MCP Memory Database - Post-Cleanup Verification Report
**Date:** 2025-10-14
**Project:** mcp-memory-ts v1.7.2
**Database:** ai-memory-bobmatnyc (Turso/LibSQL)
**Verification Type:** Comprehensive Post-Cleanup Assessment
---
## Executive Summary
**Overall Status:** ⚠️ **MOSTLY PRODUCTION-READY WITH MINOR ISSUES**
The database cleanup was largely successful, with **2,398 entities** and **200 memories** remaining after removing 1,281 low-quality entities. All critical security and data integrity checks passed. Three minor issues remain that should be addressed before full production deployment:
1. **Configuration Issue:** DEFAULT_USER_EMAIL still set to test@example.com (should be bob@matsuoka.com)
2. **NULL IDs:** 11 entities and 41 memories with NULL IDs (LibSQL quirk)
3. **Data Quality:** 1 empty memory content, 40 duplicate memories
---
## 1. Configuration Verification
### ✅ Environment Configuration
| Setting | Value | Status |
|---------|-------|--------|
| TURSO_URL | Configured | ✅ PASS |
| TURSO_AUTH_TOKEN | Configured | ✅ PASS |
| OPENAI_API_KEY | Configured | ✅ PASS |
| LOG_LEVEL | INFO | ✅ PASS |
| DEFAULT_USER_EMAIL | test@example.com | ❌ **FAIL** |
**Issue:** DEFAULT_USER_EMAIL is still set to `test@example.com` instead of `bob@matsuoka.com`.
**Impact:** Low - Database already has correct user associations, but new operations may use wrong default.
**Fix:**
```bash
# Update .env file
sed -i '' 's/DEFAULT_USER_EMAIL=test@example.com/DEFAULT_USER_EMAIL=bob@matsuoka.com/' .env
```
---
## 2. Security Verification

## 3. Data Integrity Verification
### ✅ Database Statistics
| Metric | Entities | Memories |

**Fix:**
```bash
npm run fix-null-ids -- --dry-run # Preview changes
npm run fix-null-ids # Apply fixes
```

---
## 7. Recommendations
### Priority 1: Required Before Production
**1. Fix DEFAULT_USER_EMAIL Configuration**
```bash
# Update .env file
sed -i '' 's/DEFAULT_USER_EMAIL=test@example.com/DEFAULT_USER_EMAIL=bob@matsuoka.com/' .env
# Verify change
grep DEFAULT_USER_EMAIL .env
```
**2. Fix NULL IDs**
```bash
# Preview fixes (safe)
npm run fix-null-ids -- --dry-run
# Apply fixes
npm run fix-null-ids
# Verify
npm run verify:schema
```
### Priority 2: Recommended Cleanup
**3. Clean Memory Duplicates**
```bash
# Use existing cleanup script
npm run execute-cleanup
# Select option: Remove duplicate memories (40 records)
```
**4. Remove Empty Memory Content**
```bash
# Manual SQL query or update cleanup script
# DELETE FROM memories WHERE content IS NULL OR TRIM(content) = '';
```
### Priority 3: Optional Improvements
**5. Regenerate Missing Embeddings**
```bash
# If embedding backfill script exists
npm run backfill-embeddings
```
**6. Clean Up Backup Tables**
```bash
# After verification, drop old backups to save space
# Keep only most recent backup of each table
```
