Compound Scorecard: aggregates session-level product chain scores into multi-scale verdicts. Self-similar — uses the same L0-L5 product chain at every scale. Input is an array of session levels; output is the compound score plus the scale-appropriate verdict.

> **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.
