Umbra

Most entries used an agent as a faster keyboard. A dark factory is a production line. You hand it one task. It plans the work, writes the code, tries to break the result, and refuses to ship until a different seat has reproduced the proof. Umbra is that line. Seven seats share one repository and one Band room. Lead turns a specification into numbered requirements. Builder is the only seat allowed to write the service, and it cannot grade that service. Verifier checks each requirement against a run it produced itself. UIReviewer drives the real screens at phone width and desktop width. Certifier re-executes the evidence and is the only seat that can seal a stage. Breaker is the seat that makes the line unusual. It is a different model, DeepSeek, and it has a binding veto. It races transfers, retries requests, and tries to spend the same money twice. A green report from the builder means nothing if Breaker says no. A clock watches the room every minute. When a seat hangs, the clock ends the turn and a supervisor restarts the runtime. The clock never types as the human. That line built Pocketful, a wallet in the Venmo shape, through all four stages. People pay each other, ask for money, split a bill, place a hold, correct the past, and refund what they received. Nothing is deposited and nothing is invented. Balances stay exact, and a retry cannot move the same money twice. Stage 4 sealed at revision 79af98560dd9. On the next fields, set the track to Pocketful. For technologies, pick Band, Docker, and Featherless if they are on the list.
