These files are retained to make the engineering history reproducible. None is a manufacturing release or a valid final A03 routed board.
- krt-failed and the routing-attempt Circuit JSON contain a failed KRT run: zero copper and 199 disconnected-port findings. They must not be treated as a routed PCB. - pre-a03/aura-a02-route.ses contains 372 wire paths and 82 vias, with 24 connections remaining in that router run. It predates the corrected 8 × 6 mm NAND footprint and the A03 board/thermal design. It is not compatible with the current board. - pre-a03/aura-a02-routing-draft.kicadpcb was a…
