Zero design rule errors. Three simulators in agreement. And every part on it, marked and modelled.

Claude drove KiCad and three simulators through Adom Bridge. Adom Parts Search found the parts, Adom AI Flow ran the flow, and Adom Fields checked the copper. Adom Chip Laser etched every part number, Adom Symbol and Adom L B R drew the symbols on our Open Cascade service, and the Adom wiki holds it all. One prompt, and a better board.  ## Review and tools
