Optional caller correlation ID. Unsafe or oversized values are replaced.

max length 128

Idempotency-Keystring

Stable retry key for a mutation. The key is claimed atomically before the handler runs, so concurrent retries execute the side effect at most once. Replaying the key for the same request (same method, path, workspace and JSON body) returns the original response with an X-Idempotent-Replay: true header. Reusing the key for a different request returns 409 with error code idempotency_key_reuse. A duplicate arriving while the first is still in flight waits and then replays; if the first does not finish in time the duplicate gets 409 idempotency_request_in_progress. Keys are retained for 24 hours. Only successful (2xx) responses are stored; a failed request frees the key so it can be retried.
