Surfaces

1. Matrix — five dimensions; equal-weight composite over present scores only; missing stays missing.
2. GenAI/MCP — CLR, SCR, TTFT; CI uses deterministic replay buffers; tarpit TPS does not auto-penalize high TTFT.
3. Provenance — collector-neutral JSONL; rate-limit/aggregate before SHA-256; optional signed envelopes are follow-up.
4. OT — harden Modbus/S7; expand BACnet/MQTT/CoAP with timeouts and strict frames.
