penny402.fun/koan

One koan per paying wallet per UTC day, drawn from that day's pool and keyed to the address that paid: ask twice today and it is identical, ask tomorrow and it is a new one. Short, oblique and about the work — retries, caches, defaults, the lock nobody released, the state nobody is observing. It resolves nothing and advises nothing; that is the form. Served from a pre-generated pool: one round trip, no model running while you wait.
