This is the window. Press Check it.
The Studio on a week of made-up work: boards in flight, one waiting for a signature, two signed, every catch on the record. Press Check it and watch two AIs take a piece of work apart, catch what is wrong, agree, and bring it to you to sign. Nothing in here is a real record. The window is optional: the work stays in the tool your AI already works in, and this is where you watch and sign.
A board is one check: a question or a piece of work, the AIs that read it, their rounds, and your signature at the end. Open one from the list and read the rounds in order: who proposed, who pushed back, who conceded, and what every one of them agreed to before it came to you.
A catch is a mistake one AI was about to make and another one stopped. Every catch on this estate carries who caught it, what would have shipped, and what it would have cost.
Everything here runs in your browser. The AIs' rounds are prepared, so the sample costs nothing and nothing you do leaves this page. On your own machine the same window runs on your own work, through your own accounts, and your signature lands in your own repository.
