📋 Executive Summary

Integration of @ruvector/attention (WASM & NAPI packages) into AgentDB v2 to enable state-of-the-art attention mechanisms for edge-deployable AI agents with:

• 🚀 Edge-Deployable: WASM/NAPI enables browser + Node.js (no Python/CUDA)
• 🧠 Hyperbolic Memory: Tree-structured causal memory graphs using Poincaré embeddings
• ⚡ Flash Attention: Memory-efficient attention for large episodic memories (10x reduction)
• 🌐 Graph-Aware Retrieval: GraphRoPE for hop-distance-aware semantic search
• 📊 MoE Routing: Mixture-of-Experts for specialized memory retrieval

This issue will be updated hourly with progress, metrics, and blockers. All agents coordinate through hooks and this GitHub issue.

Read packages/agentdb/docs/RUVECTOR-ATTENTION-INTEGRATION.md, the source analysis, and the progress dashboard before choosing a bounded phase or task. The issue names packages/agentdb/package.json, src/controllers/AttentionService.ts, tests/attention-service.test.ts, and benchmarks/attention-benchmark.ts as the main entry points. Done requires the selected integration work, tests and benchmarks, while preserving backward compatibility and meeting the stated coverage and performance targets.
