# retro-correlate-alerts

`station__process-control__retro-correlate-alerts` · external (needs EXECUTION_BACKEND_URL configured) · domain `process-control` · pv-relevance `non-pv`

Correlate structural clusters with adverse event patterns to find alert candidates.

> **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.
