The Opening Day
The Opening Day. REQUIRES ?url= on the paid request — a signed request without it is refused before the gate and no money moves. The launch check's signed JSON walk record (verdict, every stage, what was paid, the settlement transaction where one came back), its evidence hash bound into the purchase certificate's attests field; a conformance watch opened on the same door for seven days, each daily pass signed alone at a history URL; the host's endpoint passport URL; and one …
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
