Roulette.pretty/ no es una placa: son los footprints propios del repo.
Cifras medidas el 2026-07-27 con python tools/pcbindex.py .kicadpcb. Si esta tabla y el índice no coinciden, manda el índice — esto es texto, y el texto envejece.
El 2026-07-27 el dueño eligió quedarse con la re-colocada y ascenderla a placa principal. pic32mainrelayoutplaced.kicadpcb pasó a llamarse pic32main.kicadpcb, y con eso desaparece el problema de tener dos archivos casi homónimos en la misma carpeta.
