Semantic — deterministic

  • • Lexical retrieval, never approximate
  • • Vector tier evidence-gated OFF

Procedural — typed

  • • Plans are executable JSON
  • • Text loses the join; ours doesn't

Episodic — categorical

  • • Categories only, never payloads
  • • Self-generated by re-simulation
