# Extend a pending question's hot answer window

`POST /v1/agent-runs/{runId}/threads/{threadId}/user-inputs/{requestId}/extend`

Typing keepalive for a pending question's hot window (WIBLO-159): while the user composes an answer the client pings this (throttled) and the gateway resets the request's park timer, keeping the asking turn live. `extended: false` means the hot window is already gone (request resolved, turn settled, or sandbox stopped) — submitting the answer still works via the parked lane, so no client fallback is needed. Per-user rate-limited at 60/60s.
