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.

Passing checks, but a short history so far. Treat as provisional.
On-chain payments
Peak day 2026-09-02: 52 payments. Last indexed day 2026-09-25: 1. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 6 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
