# Replay Turn

`POST /api/admin/turn-replays/{source_message_id}`

## Request

- Base URL: `https://app.thinqos.com` (the document declares no server; this is the origin it was published from)
- URL: `https://app.thinqos.com/api/admin/turn-replays/{source_message_id}`
- Auth: none declared

Replay one visible historical turn through the production interactive path.

The endpoint intentionally runs exactly one turn. A cohort driver invokes it
repeatedly so each sample has its own Cloud Run request and trace root; a
long serial batch inside one request would exceed the request deadline and
would make per-sample infrastructure overhead impossible to reconcile.
