AgentDB v2.0 Implementation Checklist

📋 Pre-Migration Phase

Documentation Review

• Read SCHEMA-V2-SUMMARY.md (10 min)
• Review migration-v1-to-v2.md (20 min)
• Browse example-queries.sql (10 min)
• Study schema-diagram.md (15 min)

Environment Preparation

• Verify Node.js installed with better-sqlite3
• Check current database location: /workspaces/agentic-qe-cf/agentdb.db
• Verify disk space: ~100MB free for migration
• Ensure no running processes using databases:

  lsof | grep agentdb.db
  lsof | grep patterns.db
  lsof | grep memory.db
  

Backup Current State

• Create backup directory:

  mkdir -p /workspaces/agentic-qe-cf/.agentic-qe/backup-$(date +%Y%m%d-%H%M%S)
  

• Backup agentdb.db (1,759 episodes)
• Backup .agentic-qe/patterns.db (0 patterns, schema only)
• Backup .agentic-qe/memory.db (Q-values, metrics)
• Verify backups are readable:

  node -e "const db = require('better-sqlite3')('./backup/agentdb.db', {readonly:true}); console.log('Episodes:', db.prepare('SELECT COUNT(*) as c FROM episodes').get().c);"
  

---

🔨 Migration Phase

Step 1: Create v2.0 Schema

• Create new database from schema:

  node -e "
  const Database = require('better-sqlite3');
  const fs = require('fs');
  const db = new Database('./agentdb-v2.db');
  const schema = fs.readFileSync('./docs/database/schema-v2.sql', 'utf8');
  db.exec(schema);
  db.close();
  console.log('✅ Schema v2.0 created');
  "
  

• Verify schema version:

  node -e "const db = require('better-sqlite3')('./agentdb-v2.db', {readonly:true}); console.log(db.prepare('SELECT * FROM schema_version').get());"
  

Step 2: Migrate Episodes (1,759 rows)

• Create migrate-episodes.js from migration guide
• Run episode migration:

  node migrate-episodes.js
  

• Verify episode count:

  node -e "const db = require('better-sqlite3')('./agentdb-v2.db', {readonly:true}); console.log('Episodes:', db.prepare('SELECT COUNT(*) FROM episodes').get());"
  

• Expected output: Episodes: { 'COUNT(*)': 1759 }

Step 3: Migrate Patterns (0 rows expected)

• Create migrate-patterns.js from migration guide
• Run pattern migration:

  node migrate-patterns.js
  

• Expected: "No patterns to migrate" message

Step 4: Migrate Learning Data

• Create migrate-learning-data.js from migration guide
• Run learning data migration:

  node migrate-learning-data.js
  

• Verify tables populated:
  • learning_metrics
  • q_values
  • learning_experiences

Step 5: Verification

• Create verify-migration.js from migration guide
• Run comprehensive verification:

  node verify-migration.js
  

• Check output for:
  • Episodes: 1,759 ✅
  • Schema version: 2.0.0 ✅
  • Indexes created: 40+ ✅
  • Views created: 3 ✅
  • Triggers created: 5 ✅
  • Sample query performance: < 100ms ✅

---

✅ Post-Migration Phase

Switch to v2.0

• Stop all processes using old database
• Rename old database:

  mv agentdb.db agentdb-v1-backup.db
  

• Activate new database:

  mv agentdb-v2.db agentdb.db
  

Performance Testing

• Create test-performance.js from migration guide
• Run performance benchmarks:

  node test-performance.js
  

• Verify all queries < 100ms:
  • Pattern by ID: < 1ms
  • Framework filter: < 10ms
  • Similarity search: < 50ms
  • Full-text search: < 100ms
  • Aggregate queries: < 100ms

Application Code Updates

• Update database connection to use single unified database
• Remove references to patterns.db and memory.db
• Test all existing queries work with new schema
• Update any hardcoded column references

Data Population

• Run test generation to populate new columns:
  • episodes.test_framework
  • episodes.test_type
  • episodes.coverage_before
  • episodes.coverage_after
  • episodes.test_count
  • episodes.quality_score

---

🔍 Validation Phase

Data Integrity Checks

• Verify no duplicate patterns:

  SELECT code_signature_hash, framework, COUNT(*)
  FROM test_patterns
  GROUP BY code_signature_hash, framework
  HAVING COUNT(*) > 1;
  

  Expected: 0 rows

• Check JSON validity:

  SELECT COUNT(*) FROM test_patterns
  WHERE json_valid(code_signature) = 0
     OR json_valid(test_template) = 0
     OR json_valid(metadata) = 0;
  

  Expected: 0

• Verify constraint compliance:

  SELECT COUNT(*) FROM episodes
  WHERE (reward < 0 OR reward > 1)
     OR (coverage_before < 0 OR coverage_before > 100)
     OR (coverage_after < 0 OR coverage_after > 100);
  

  Expected: 0

Query Functionality Tests

• Test FTS search works:

  SELECT COUNT(*) FROM pattern_fts;
  

• Test views are accessible:

  SELECT COUNT(*) FROM v_pattern_performance;
  SELECT COUNT(*) FROM v_agent_learning_progress;
  SELECT COUNT(*) FROM v_top_patterns;
  

• Test triggers fire correctly:

  • Insert test pattern usage
  • Verify usage_count increments
  • Verify success_rate updates
  • Verify trend calculation works

Performance Validation

• Run ANALYZE to update statistics
• Verify index usage with EXPLAIN QUERY PLAN
• Check cache effectiveness:

  SELECT COUNT(*) FROM pattern_stats_cache;
