# temporal-plausibility

`station__temporal__temporal-plausibility` · external (needs EXECUTION_BACKEND_URL configured) · domain `temporal` · pv-relevance `non-pv`

whether TTO falls within an expected mechanism-based onset range.

> **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.
