V3 QE Memory Unification

Purpose

Guide the implementation of a unified memory system for all QE domains using AgentDB with HNSW indexing, providing 150x-12,500x faster semantic search and cross-domain knowledge sharing.

Activation

• When consolidating QE memory systems
• When implementing cross-domain knowledge sharing
• When migrating from legacy memory (SQLite, markdown, in-memory)
• When optimizing search performance
• When integrating SONA learning patterns

Unified Memory Implementation

1. QE Unified Memory Service

// v3/src/memory/QEUnifiedMemory.ts
import { AgentDB, HNSWIndex } from '@agentdb/core';

export class QEUnifiedMemory {
  private readonly db: AgentDB;
  private readonly indexes: Map<string, HNSWIndex>;

  constructor(config: QEMemoryConfig) {
    this.db = new AgentDB({
      storagePath: config.storagePath || '.agentic-qe/memory',
      embeddingDimensions: 1536,
      persistenceStrategy: 'hybrid'
    });

    this.indexes = new Map();
    this.initializeIndexes(config);
  }

  private initializeIndexes(config: QEMemoryConfig): void {
    // Domain-specific HNSW configurations
    const domainConfigs: Record<string, HNSWConfig> = {
      'defect-patterns': { M: 32, efConstruction: 400, efSearch: 200 },
      'coverage-analysis': { M: 16, efConstruction: 200, efSearch: 100 },
      'test-suites': { M: 8, efConstruction: 100, efSearch: 50 },
      'learning-patterns': { M: 24, efConstruction: 300, efSearch: 150 },

      'coordination': { M: 8, efConstruction: 100, efSearch: 50 }
    };

    for (const [domain, hnswConfig] of Object.entries(domainConfigs)) {
      this.indexes.set(domain, new HNSWIndex(hnswConfig));
    }
  }

  // Store with automatic embedding and indexing
  async store(entry: QEMemoryEntry): Promise<string> {
    // 1. Generate embedding
    const embedding = await this.generateEmbedding(entry.content);

    // 2. Store in AgentDB
    const id = await this.db.store({
      id: entry.id || crypto.randomUUID(),
      namespace: entry.domain,
      data: entry.content,
      embedding,
      metadata: entry.metadata,
      ttl: entry.ttl
    });

    // 3. Index in HNSW for fast search
    const index = this.indexes.get(entry.domain);

      }
    }

    return results
      .sort((a, b) => b.similarity - a.similarity)

export class QESONAMemory {
  constructor(
    private readonly unifiedMemory: QEUnifiedMemory,
    private readonly sonaProvider: SONAProvider
  ) {}

  // Enable SONA for pattern learning
  async enableSONAIntegration(config: SONAConfig): Promise<void> {
    await this.sonaProvider.initialize({
      mode: config.mode || 'real-time',
      adaptationTimeMs: config.adaptationTimeMs || 0.05,
      patternStorage: true
    });

    // Subscribe to memory events for pattern learning
    this.unifiedMemory.on('stored', async (entry) => {
      await this.learnFromEntry(entry);
    });

    this.unifiedMemory.on('searched', async (query, results) => {
      await this.learnFromSearch(query, results);
    });
  }

  private async learnFromEntry(entry: QEMemoryEntry): Promise<void> {
    if (entry.domain === 'learning-patterns') {
      await this.sonaProvider.adaptPattern({
        pattern: entry.content,
        source: entry.domain,
        timestamp: new Date()
      });
    }
  }

  private async learnFromSearch(
    query: string,
    results: SearchResult[]
  ): Promise<void> {
    if (results.length > 0) {
      await this.sonaProvider.reinforcePattern({
        query,
        topResults: results.slice(0, 3),
        timestamp: new Date()
      });
    }
  }

  // Get pattern recommendations
  async getRecommendations(context: string): Promise<PatternRecommendation[]> {
