The spiral used only the least-waste rows and columns. Those often make one pair of blocks the larger on both axes, so it overlapped itself and placed nothing, leaving Fill at two blocks. It now also tries every four-block combination and takes one that holds more parts than both the least-waste spiral and the two-block layout, so ties keep today's layout. A 9 x 6.5 part on a 60 x 120 sheet goes from 109 to 112. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
