Component: Rim (Value Network) — Spec §2.1. Schema validator for value network data completeness. Instead of classifying state (no equation yet), validates that sufficient data exists to COMPUTE rim health. Returns data_complete=true when all required metrics are present and non-zero.

> **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.
