+/**
+ * V3 Integration Module
+ *
+ * Main entry point for the agentic-flow@alpha integration module.
+ * Provides deep integration with SONA learning, Flash Attention,
+ * and AgentDB for maximum performance and capability.
+ *
+ * This module implements ADR-001: Adopt agentic-flow as Core Foundation
+ *
+ * Key Features:
+ * - SONA Learning: Real-time adaptation with <0.05ms response
+ * - Flash Attention: 2.49x-7.47x speedup with 50-75% memory reduction
+ * - AgentDB: 150x-12,500x faster search via HNSW indexing
+ * - Intelligence Bridge: 19 hook tools + 9 learning tools
+ * - Trajectory Tracking: Experience replay for continuous learning
+ *
+ * Usage:
+ * ```typescript
+ * import { createAgenticFlowBridge } from './v3/integration';
+ *
+ * const bridge = await createAgenticFlowBridge({
+ *   features: {
+ *     enableSONA: true,
+ *     enableFlashAttention: true,
+ *     enableAgentDB: true,
+ *   }
+ * });
+ *
+ * // Get SONA adapter for learning
+ * const sona = await bridge.getSONAAdapter();
+ * await sona.setMode('real-time');
+ *
+ * // Get Attention coordinator
+ * const attention = await bridge.getAttentionCoordinator();
