Database Init Implementation - Extraction Report

Summary

Successfully extracted all database initialization code from the old monolithic src/cli/commands/init.ts into the new modular src/cli/init/database-init.ts.

Implemented Functions

1. initializeDatabases(config: FleetConfig) - Main Entry Point

• Orchestrates all database initialization in correct order
• Calls 4 sub-initialization functions sequentially

2. initializeMemoryDatabase() - Memory Manager

Extracted from: init.ts line 2048-2068

• Creates SwarmMemoryManager database at .agentic-qe/memory.db
• Initializes 12 tables for persistent memory storage
• Implements 5 access control levels (private, team, swarm, public, system)
• Dynamic import of SwarmMemoryManager
• Verifies initialization with stats check
• Proper cleanup with close()

3. initializeAgentDB(config: FleetConfig) - Learning System

Extracted from: init.ts line 2010-2041

• Creates AgentDB database at .agentic-qe/agentdb.db
• Replaces deprecated patterns.db with vector-based learning
• Configuration:
  • enableLearning: true
  • enableReasoning: true
  • cacheSize: 1000
  • quantizationType: 'scalar'
• HNSW vector search enabled (150x faster)
• Reflexion pattern + Q-values for learning
• Used by all 18 QE agents
• CRITICAL: Calls initialize() before getStats()

4. initializeLearningSystem(config: FleetConfig) - Learning Config

Extracted from: init.ts line 2073-2110

• Creates .agentic-qe/config/learning.json with full configuration:
  • Learning rate: 0.1
  • Discount factor: 0.95
  • Exploration rate: 0.2 (with decay)
  • Target improvement: 20%
  • Replay buffer: 10,000 entries
  • Batch size: 32
• Creates .agentic-qe/data/learning/ directory
• Creates learning state JSON with version tracking

5. initializeImprovementLoop(config: FleetConfig) - A/B Testing

Extracted from: init.ts line 2226-2267

• Creates .agentic-qe/config/improvement.json with:
  • 1-hour cycle interval
  • A/B testing enabled (sample size: 100)
  • Auto-apply disabled (requires user approval)
  • 3 optimization strategies (parallel, retry, resource)
  • Statistical significance testing (p < 0.05)
• Creates improvement state JSON at .agentic-qe/data/improvement/state.json

Implementation Details

Imports Added

import * as path from 'path';
import * as fs from 'fs-extra';
import chalk from 'chalk';
import { FleetConfig } from '../../types';

Version Tracking

const packageJson = require('../../../package.json');
const PACKAGE_VERSION = packageJson.version;

Dynamic Imports (Preserved from Original)

• import('../../core/memory/AgentDBManager')
• import('../../core/memory/SwarmMemoryManager')

Verification

✅ No TODOs remaining - All placeholders replaced with real implementation ✅ Build successful - TypeScript compilation passes ✅ Exact code extraction - All logic, error handling, and logging preserved ✅ Database paths preserved - Same paths as original implementation ✅ Configuration values unchanged - All numeric values, thresholds, and settings match

Files Modified

• /workspaces/agentic-qe-cf/src/cli/init/database-init.ts - 199 lines (was 33 lines)
  • Added 4 complete implementation functions
  • Added all necessary imports
  • Added version tracking
  • Removed all TODO comments

Next Steps

This module is now ready to be integrated into the new modular init command flow in src/cli/init/index.ts.
