With no lead-out the tool leaves a hole where it entered it. A tiny corner arc's midpoint lies on both facing sides of its hole, so the ranker scored it as an ideal two-side corner, but the tool leaves it along its 45-degree tangent: a shallow rapid to a nearby next hole re-entered the corner and crossed the hole just cut. Every outside endpoint's preferred hole chain then failed the same way, and the reorder search spent its budget on full backtracking. A 31-part plate of such parts needed 31,959 expansions against a default budget of 20,000. Hole entries whose straight rapid to the next pierce clears the hole itself now rank first, in the preferred chain and in the full search. This is a stable reorder only: no entry is dropped, and every emitted rapid is still checked. That plate now plans Ready on its first preferred pass, using 7,781 expansions; the budget is unchanged.
