NVG-SMM-001 Section 5: Compute Credibility Score from violation counts. CS = Base x Fatal x Critical x Major x Minor. Chemistry analog: rate law — CS = k[F]^0 x [C]^n x [M]^m where Fatal is a kill switch.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
