DefaultPlateFiller.PackArea (Default, Strip and both Remnant strategies)
now packs leftover parts with the shared maximal-rectangles packer instead
of bottom-left corner points. Every fit rule and pick mode is tried; the
layout placing the most parts, then box area, per priority tier wins, and
the strategy's own fill comparer breaks ties so remnant strategies keep
their clear side. PackBottomLeft and PackEngine are removed.
Rectangle-lane benchmark (91 strict + 77 boxable jobs) against the old
packer: no strategy lost a valid layout; Default, Vertical Remnant,
Horizontal Remnant and Strip complete 2-3 more strict jobs, and Strip
gains a valid one. Cost on jobs complete in both runs falls for every
strategy (Default -0.6% strict, -2.7% boxable). Default is about 7-10%
slower on the changed jobs.
Golden layouts for Default and both Remnant strategies are re-captured;
each is complete, passes NestLayoutCheck and repeats exactly.
Pin committed fulfillment and exact placement poses for Default, Strip,
Vertical Remnant, and Horizontal Remnant through the production
PlateNesterFactory + NestJobRunner path, plus deterministic poses for
OrderedPlateNester via its StockLadder wiring (no legacy counterpart) and
authoritative progress-stage sequences for StockLadder and
FixedStrategyNestingEngine. Captured at 42bbde7 (post ShrinkFiller axis
fix); these fixtures are the regression net for the legacy-engine removal.
Note: Strip is pinned on a rectangle-variety job. On dense mixed-shape
jobs the iterative shrink path intermittently proposes overlapping
candidates (pre-existing scheduling nondeterminism), so its mixed-geometry
layout is deliberately not pinned.
