A part with about 1,700 holes (P241017-01) never planned: material
capture paired every boundary with every other one and lead checks
scanned every boundary per lead, so both hit the 1M native query limit
and the plate fell back to an unverified best-effort plan.
- Material capture sweeps boundary extents along X and queries only
pairs the lead checks' per-pair clearance cannot skip, in the full
scan's order.
- Material with 64+ boundaries keeps a grid of boundary extents. Lead
checks, contour-joint matching and replay's contour accounting query
only nearby boundaries; ray parity reads only holes on the point's row.
- Only native queries that run are charged to the budget; skipped far
material no longer costs its full boundary count.
- The search looks up chosen holes and route ranks instead of scanning.
With that the plate plans Ready, but in 189 s: every step re-emitted
and re-checked all holes already cut. On parts with 64+ contours a
middle hole step now checks only the contour it adds, continuing the
completed-contour state its prefix left (ReleasedContourState.Continue).
It falls back to the full prefix whenever it cannot continue exactly,
and the last contour still checks the whole part from before it.
Isolated contour emission clones only the chosen contour.
P241017-01 now plans Ready in 5.4 s with an identical route, expansions
and rapid travel. Core and engine suites pass; the problem-nest corpus
matches the unchanged commit's outcomes and expansions.

Some jobs cut only cutouts into a supplied blank, such as instrument holes
in a purchased door that is the whole sheet. Its outline has to be known
to the planner (the blank is material that leads, rapids and cut-offs must
respect) but must never be pierced, led or cut.
A new DisplayPerimeter layer marks that outline. It is material, so
nesting, containment, lead clearance and automatic cut-offs all see the
blank; a door that fills its sheet leaves cut-offs nothing to cut. Cutting
preparation keeps it out of the contours entirely: with no cut perimeter
every contour is a hole with internal leads, and the search, best-effort
and safest-route paths stop offering a perimeter. Replay refuses any run
along the display perimeter and completes once every other ring is cut.
A display perimeter must be one whole closed contour enclosing every other
contour; a mixed ring, one inside another contour, or a second one is
refused with that reason. Saving, drawing and posting it are still to do.
A hole can now be declared a tabbed cutout in the CAD Converter: pick a
circle or any edge of a closed hole, set the tab count and width, and drag
the tabs around the hole. The definition persists on the drawing and in the
nest file, and stays editable from the source entities.
The builder replaces the hole with open cut pieces and uncut spans on a new
Tab layer. Tabs are material, so area, nesting and overlap checks still see
a closed hole, but they are never cut. Plan Cutting and Assign Lead-ins cut
each piece from the slug with the internal lead-in and no lead-out. A lead
that would reach back over a tab is mirrored, and an arc lead onto an arc
pierces straight in. Planning accounts for each span between tabs and runs
the open-cut proof, so its own tabbed cutouts certify; tabs followed by a
lead-out are still refused. Pre-post review flags programs that still
contain tab motions.

A nominal ring may close within NominalContourClosure.Tolerance, and replay
already carried that admitted gap as slack when bridging it shortens the cut.
When the gap instead lies across the following edge, the emitted path starts
that edge at the ring's end point, so the cut is longer by the gap. Two checks
still compared at the exact epsilon and refused it as "invalid input":
- the retrace guard rejected any surplus length beyond 1e-8;
- Follows matched the edge's leftover sliver against the next nominal entity
and failed its direction check.
Both now use the ring's admitted slack, the same bound the shortfall and the
nominal side of Follows already use. Exactly closed rings keep the epsilon, and
a second circuit still exceeds the slack by a whole ring.
A0227-08's sprocket outline misses its start by 1e-6 and refused planning in
both keep-order and reorder modes; it now plans Ready and applies.

Capture and preparation agree that a nominal contour may close within
NominalContourClosure.Tolerance inclusively, which converted drawings rely on:
the sampled production corpus carries vertex gaps up to 1e-6. Replay
verification still compared those rings at the exact geometry epsilon, so the
one joint a rotated tool path legitimately bridges refused the whole plate
after the search had already spent its budget.
Census of 91 plates from 60 stored nests: every searched plate containing such
a seam refused with contour-accounting (4 plates, 76.5s of wasted search, worst
71.7s for one 11-part plate), and none of the 42 ready plates had one. Replay
now carries that same admitted endpoint gap as positional and length slack for
the affected ring only. Direction sign, coverage order, retrace detection, ring
counting and selected-emission binding keep the exact epsilon, and capture's
closure admission is unchanged.
With the fix the census yields 45 ready plates instead of 42, no plate changed
any other way, and expansion counts are identical wherever status matched.
P260805-01's 16-part plate plans in 0.76s rather than refusing after 4,129
expansions.
Tests: SeamClosureReplayTests covers seams of 0, 5e-7 and 1e-6 plus four
accounting faults (missing edge, reversed edge, interior shift beyond the
admitted seam, second circuit) that must still refuse, and the beyond-tolerance
capture refusal. OpenNest.Tests 3751, OpenNest.Engine.Tests 690 and
OpenNest.IO.Tests 79 pass; Windows-only projects cannot build on Linux.
