Antimatter

POST/api/traces/replaySigned in session

Runs the captured request again, against the same model or another one, and returns both answers with their costs and latencies. A replay is a real request through the one dispatch path: it is metered and charged. With quote: true nothing runs: the answer is the most the replay could be billed, the gateway's own worst case for that request on that model.
