NER-PIM: Classifies system behaviors by T1 primitive composition. Maps observable system dynamics to primitive spans using BIO-inspired tagging.

> **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.
