Profiling the cutout pre-pass on real round-part jobs put ~97% of its time in the frame-wall NestLayoutCheck.Clears inside CutoutCirclePacker.Fill. Ear-clipped round frames make every perimeter/insert triangle pair overlap, so a clear pair runs hole subtraction for every pair. The same question repeats for every frame angle and repeated frame instance, because Automatic inserts get identical frame-local poses. - CutoutMemo, one per Prepare, replays geometry reads, circle items and Clears answers. Keys hold geometry by reference, pose bit patterns, argument order and spacing. It is threaded through CutoutCirclePacker.Fill and the router's round-only path. - TriangulatedRegion.SubtractAllHoles measures each piece's bounds once, skips holes and hole triangles that no piece reaches, and ping-pongs the remainder between scratch buffers instead of copying it into pooled ones. Clip arithmetic and order are unchanged. Bundles are byte-identical on 14 real and 10 synthetic ring jobs. Pre-pass time over the real set drops from 99.6 s to 10.1 s (N0414-02 35.8 s -> 0.6 s).
