Our build order: one net through every stage end to end first, then widen. D12.
How it looks
Drawing: our build order (decision D12)
Rows are nets on the board, columns are the stages a net passes through inside Ants. A thin slice fills one whole row first, instead of one whole column.
How it works
Where it fits
The first job on the Ants engine track. "Done" is judged by the benchmark referee (KiCad DRC), not by Ants itself.
