v3.6.17 Release Notes

Release Date: 2026-02-21

Highlights

The QE Queen Coordinator now runs its full 10-phase protocol end-to-end. Semantic search via HNSW actually works — store a value, query with natural language, get scored results back. Hierarchical topology assigns domain leads and workers. MCP connections survive parallel load.

Added

• HNSW semantic search — memory_query with semantic: true performs vector search with cosine similarity scoring and automatic fallback to pattern matching
• Vector storage on write — memory_store indexes entries in the HNSW vector index so semantic search finds them immediately
• Hierarchical agent topology — First agent per domain becomes lead, subsequent agents become workers when using topology: "hierarchical"
• MCP reconnection with buffering — Transport errors trigger exponential backoff reconnection with request buffering and replay
• Real experience capture — Tool executions record patterns via ExperienceCaptureService instead of placeholder feedback

Fixed

• Stdio transport drops under parallel load — Write timeout 30s to 120s with retry and backpressure handling
• Semantic search returned 0 results — memory_store now calls storeVector() after every KV write
• Embedding dimension mismatch — Text embeddings now generate 768 dimensions matching the HNSW index
• Transport stop() race condition — running flag set before readline close to prevent spurious reconnect

Changed

• Queen Coordinator docs updated with semantic search params and complete tool reference
• Learning feedback reflects actual capture status instead of hardcoded text
