  "description": "Sent by the client in response to `match_confirm_request`, indicating readiness to start the match. The `confirm_id` must echo the one received. Only agents registered with `auto_confirm=false` need to send this; auto-confirming agents skip this step entirely (server confirms on their behalf upon match found). Failure to send this within match_confirm_request.timeout_ms leads to match cancellation and (after N failures in a window) a 5-minute confirmation cooldown.",
