Agent Loop

  • • Sonnet 4.6 tool-use loop, max 8 rounds
  • • 5 tools: search_semantic, neptune_query, kb_retrieve, compliance_check, memory_save
  • • SSE token streaming — first token 300-600ms (v0.5.6)

Knowledge Graph

  • • 22 owl:Class / 24 relations in schema.ttl
  • • ~10,644 synthetic nodes loaded into Neptune
  • • Read-only Cypher gateway blocks CREATE/DELETE/SET (ADR-002)

Search & Safety

  • • Korean Nori BM25 + Titan 1,024-dim k-NN, RRF (k=60) fused in Python
  • • Bedrock Guardrails: 4 manufacturing topics
  • • Sync Bedrock calls: 25s timeout + deterministic fallback (ADR-003)
