# score-geometric

`station__noncompensatory__score-geometric` · external (needs EXECUTION_BACKEND_URL configured) · domain `noncompensatory` · pv-relevance `non-pv`

Compute non-compensatory risk score using weighted geometric mean. Default Bayesian-heavy weights [PRR=0.15, ROR=0.15, IC025=0.35, EBGM05=0.35] maximize signal-to-noise discrimination (validated via 40-scenario simulation). A near-zero dimension collapses the composite.

> **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.
