`chat-turn.py`; router verdicts, H4 input/output scan, action-gate decisions,
H5 chat audit, H6 token metrics, evidence source selection, and operator action
execution remain harness-owned.

- `/chat` UI shows actor/role scope, `mode/risk/decision` badges, certified answer,
evidence sources, registered operator actions, action-gate status, router details,
and audit hash. Side-effect requests outside registered actions return governed
`BLOCK` or `NOT_SUPPORTED` responses.
