Product Chain Scorecard: scores a session (or any work unit) on how far it advanced through the T1 primitive product chain. L0=Void identified, L1=State measured, L2=Compared, L3=Acted, L4=Persisted, L5=Shipped. Self-similar across scales: session, chain, directive, strategy.

> **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.
