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.

Plates with staged automatic scrap cut-offs could not be planned: P260810-01
plate 1 ran out of budget even at 10x effort, while the same plate plans
Ready in 3.6k expansions without the lines. A cut-off was one fixed program
cut whole before every part its line passes through, which dragged the tour
to the middle of the sheet and left the head at the far edge of the line;
and cutting every line first (the rejected alternative) weakens the sheet
and breaks the containment operators rely on when they fast-forward a
changed program.
A cut-off stays one definition, but Plate.RegenerateCutOffs now makes one
part per trimmed segment, each with its own place in the cut sequence.
CutOffSegments gives each segment the span of the nominal line it stands
for (end of the segment before it to start of the one after), and the
dependency rules of the planner and Part Sequencing use that span, so a
segment precedes only the parts beside it. The free-order search plans the
parts as if the segments were not there, so adding lines no longer changes
a plate's route, then CutOffInsertion slides each segment into the latest
gap before its first part where the rapid into its pierce and the rapid
from its end cross nothing cut before; only when one fits nowhere is the
plate searched with the segments among the parts. The search looks through
segments wherever they sit (entries face the next part, hole routes rank
from the pre-segment position, rapids are still checked from the segment's
end), so an applied plan replanned with the order kept replays Ready.
Segments saved out of consecutive order are recorded per segment in the
.nest file (`segments`); older readers load them consecutively.
P260810-01 plate 1 now plans Ready in 3639 expansions with every check
passing; rapid travel 1836 against 1547 without the lines. Plates without
cut-offs keep their PlanningCharacterizationTests digests, and the
problem-nest corpus has no plate below its baseline.

Cut planning should rank routes safest first, then fastest, but a plate whose
strict search hit its expansion budget was simply refused ("no plan found
within the search limit"), even when a route with a few reviewable rapid
crossings existed. Scrap cut-offs make this common: their trimmed segments
can wall off a column of parts, and rapids are straight.
When both the free-order and current-order searches stop at the limit, the
batch now walks a greedy safest route from each input, replays it with fresh
checks, and keeps the one with fewer violations (material first, then rapid
crossings, then the rest), then less rapid travel. A route that passes every
check is an ordinary Ready plan; otherwise it is an unverified BestEffort
that lists every violation and applies only with explicit acceptance. Routes
with any motion into material are never offered, so the strict refusal and
its lead-in advice stand.

Plan Cutting is now the only automatic lead-in assignment, and parts the
support grid cannot hold level are reported wherever they lack a
steadying tab.
- Remove Assign Lead-ins (plate and nest), LeadInAssigner, the lead-in

and the grid cannot hold the part (SupportTabSettings)
- New PartSupport finding: Plan Cutting replay and best-effort plans
warn when a drawing pin, a lead-in that does not fit or no single tab
leaves a part unsteady; the pre-post review checks each placed
program's outside tab gap. These warnings replace the advisory
weak-tab notes; only the inside-corner tab note stays advisory, and
never for a pin
- Pinned perimeters keep their pin but carry the support analysis
- Draw grid points as pixel-snapped squares without anti-aliasing
- Post fixtures build lead-ins through a test-only TestLeadIns helper
- Docs: support tabs, pre-post verification and planner notes

The best tab point used to land in inside corners: equally good points
run along a straight edge, vertices were tried first and the first tie
won. Operators cannot grind a nub flush there.
- SupportAnalyzer finds inside corners (inward-turning vertex runs of at
least 30 degrees, so chorded fillets count) and keeps tab points a
clearance from them; of equally good points it picks the one farthest
from an inside corner. Plan Cutting and the overlay use twice the tab
size; AcceptsTabAt rejects closer points
- When no steadying entry has a lead-in that fits, the search falls back
to entries clear of inside corners, then to every entry, each ordered
by how well the tab steadies the part, keeping only the steadiest that
fit
- Replay notes parts whose planned tab cannot hold them level or sits in
an inside corner; the notes are advisory and leave a Ready plan Ready
- Console/MCP plate summaries print a ready plan's notes
- docs/support-tabs.md and cutting-planner notes

Console --plan-cutting and MCP plan_cutting run the planner at the default
effort; only the desktop exposes the setting. Adding a corpus nest must keep
the corpus server selected until the save, and the command is Nest > Edit.
Tools > Options > Cut planning effort (default 1.0, 0.5-10) multiplies the
desktop cut planner's per-plate expansion budget for both the free-order
search and the current-order retry. The budget counts expansions, not time,
so the setting is how faster hardware can be spent on hard plates.
The panel reads the setting on the UI thread and passes it to
CuttingPlanBatch.Capture; the worker never reads settings. The 1,000-
expansion first pass stays fixed: it is a cheap probe for easy plates, so a
higher effort only adds work where the full search runs. A plate refused
at the search limit now says the effort can be raised, without promising a
plan. The default keeps today's budgets and characterization digests.
Console, MCP and API do not run the cut planner, so they get no option.

Console --plan-cutting and MCP plan_cutting/apply_cutting_plan run the

which is not posting consent. Console --no-fill plans a loaded nest as
is; a blocked plan exits 2 and saves nothing. Scrap cut-offs stay
desktop-only.

An attempt along a part order stopped backtracking after 8 x entries x
contours expansions without progress, with contours taken as the most of
any part on the plate. One many-holed part therefore let every blocked
part, even a two-contour tab, replay its predecessors' entries for the
whole of that allowance; a plate whose rounds each stalled that long
ran out of budget before the recovery pass that would have finished it.
Along an order the stall now uses the larger contour count of the blocked
part and of the part cut just before it, whose departure a retry changes,
capped by the old limit. The sequence-free recovery pass keeps the plate
maximum. Planning characterization digests are unchanged.
The optional private-fixture test now also runs RecoveryCuttingNestPath
with default lead-ins, and requires that file's plates to plan within
60% of their budget.

The cut planner's directed-contour recovery pass gave up on plates the
full search could solve, so they ended "no plan found within the search
limit":
- Each hole was checked as an isolated probe that repeats the part's
scribes, so every hole-to-hole hop was checked as a detour through
the scribe start. Scribes and other open cuts are now checked once
from the arrival, and each hole as a direct hop from the one before.
- Hole entries were ranked only by pierce distance, so the departure
often ran back across the hole just cut. The nearest hole is still
tried first, but its entries that leave toward the holes still to
cut come first.
- The first-ranked outside entry could spend the whole recovery
allowance. Each outside entry now gets a share of what is left.
The optional private-fixture test now takes its config key, adding
RecoveryCuttingNestPath; it fails on the old search and passes now.

A plate of at least 200 parts with no cutoffs or prerequisites, whose
part centres bin into rows and columns within a quarter of the smallest
part extent, is toured line by line in alternating directions. Each row
and column gap must be wider than that tolerance, each cell may hold
only one part, and at least a quarter of the cells must be filled
(interleaved rows fill half). The route runs along whichever axis, from
whichever corner, is shortest from the start point.
This replaces the travelling-salesman 2-opt/Or-opt passes, which took
about 8 s on 5,742 parts. It is still only a proposal: the joint search
checks every rapid and lead, and replans after a learned rule use the
general order. Smaller plates, and the characterization fixtures, keep
their order unchanged.
The washer nest's plate 1 now plans Ready in about 44 s (was 54 s), with
86k expansions against 91k.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A lead check scanned every other part's material with native contact
queries. On the 5,742-washer plate that was about 80% of planning and
it never finished inside 120 s.
The earlier extent filter (reverted in ea1270e1) used a fixed 0.001 gap,
which native line/circle rounding can exceed for long leads beside small
circles. This skip adds 1e-6 times the span of both extents. The
discriminant's rounding is bounded by about 1e-7 times that span, and
about 2e-9 is seen. So a skipped material has no native contact, and the
900000-long lead beside a small circle is still checked. Each skipped
scan is charged to the native query budget as if it ran. Ray parity is
still asked natively unless the lead's midpoint is outside the
material's Y range. The pierce zone skips only material farther than its
radius by the same gap.
A randomized test checks that skipped material never has a native
contact. It fails with the span allowance at zero and passes with it as
low as 1e-8. Plate 1 of the washer nest now plans Ready in about 54 s.

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.

PEP-converted incremental programs round every move, so a long contour
can end 1-1.4e-6 off its start. Material capture refused it as open
("blocked: unsupported geometry"), and a gap right at the 1e-6 boundary
could pass material capture yet fail preparation.
On the planner's owned clean copy only, close incremental contours whose
gap exceeds 1e-8 but stays within what their rounded moves could
accumulate (capped at Tolerance.Epsilon); the next motion absorbs the
correction so nothing later moves. Absolute programs, larger gaps and
the drawing itself are untouched.

Pinned-lead and locked-lead warnings named a Drawing Pins Off command and a
Clear Lead-ins command that the desktop does not have; name Plate > Remove
Lead-ins and spacing instead. Closing Plan Cutting no longer claims nothing
changed after lead-ins or cut-offs were cleared, the no-stock reason no
longer says the part is larger than every sheet when only the usable area at
the checked rotations is too small, and the console says whole-job engines.
Remove a private part reference from the lead-in notes, fix the Options and
New menu paths, say that release ZIPs never auto-update, describe current
Cincinnati CL ordering, clamp validation coverage and empty-plate saving,
list every built-in engine, and drop internal decision labels.
The best-effort fallback (used whenever a part has touching or uncertain
material boundaries, which sends the whole plate there) cut each part's holes
in raw source order with the nearest entry. On hole grids that order
doubles back, so the rapids between holes cross; any crossing means a
shorter uncrossed order exists. On A0228-01 plate 1 this cost ~300 in of
rapid travel and drew crossing rapids on PT08 in the simulator.
Tour the holes with CuttingHoleOrder (the nearest-neighbour + 2-opt/Or-opt
proposal the strict search already uses), as an open path from the arrival,
perimeter still last. Hole-centre selection is shared with the strict search.

Staged cut-offs were appended after every part, so a kept order (the
"Keep the current part order" option, or the fallback after a free
search runs out of budget) always conflicted with any cut-off crossing
a part. PlateSequencing.PlaceCutOffs moves each new cut-off to just
before the first part it crosses, separators last, without moving
anything else; the panel applies it after staging.
The free search also learned "cut the cut-off first" only after a full
stall, re-planning the many-holed parts before it. A cut-off is a fixed
program that never gets harder to cut earlier, so a crossing approach
into a non-separating cut-off now teaches that rule at once. On the
reported 35-part plate this drops the plan from 23,930 expansions (over
the 20,000 budget) to 15,605.

A converted outline whose seam closes within the admitted 1e-6 gap could
only be entered at its seam: entered anywhere else, the arc after the
seam started off its own circle and every emission was refused as an
inconsistent radius. The search then spent its whole budget on that
part and the plate never planned. Emission now bridges the gap with a
straight move and cuts the arc as drawn; the verifier already admits
that slack. An entry on the seam vertex is left as before.
Each prefix of a part re-checked its earlier contours' leads against
every other part's material. One search now remembers each verdict by
the lead curve's exact bits and the material's reference, charging the
same native query budget; replay never uses it. On the reported plate
the memo alone gives a byte-identical result in 57 s instead of 12 min 47 s;
with the seam fix the plate plans Ready in about 17 s.

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.

Breakoffs are now picked by their joining line, default to the smaller side as scrap
(flippable), and cut that line between tabs on a new Break layer instead of slots.
Plan Cutting and Assign Lead-ins enter each cut from the scrap with the nest's internal
lead-in, or pierce on the line without one; checks treat break cuts as intentional open
cuts that are not material.

NestPipeline.Run now bundles parts that fit other parts' enclosed cutouts
into their frames before the selected engine, for desktop, Console, MCP and
API alike. A valid complete bundled trial is kept; a refused trial falls back
to the ordinary solve (reason on RefusedCutoutTrial), and an incomplete trial
is compared with it, keeping whichever valid proposal places more. An
incomplete but valid trial is now keepable like any incomplete result.
Expanded sheets list each frame's inserts before the frame, so the committed
order cuts every insert before the cutout that releases its slug.

Assign Lead-ins (LeadInAssigner) now leaves every unlocked part with active
drawing pins unchanged and returns those parts, so it never overwrites a pin
with the plate's settings; the desktop names them ("N parts kept their
drawing lead-ins (plate P: parts ...); use Plan Cutting to apply their
drawing pins."). Parts without pins, with pins switched off, or locked are
assigned or skipped exactly as before.
The pre-post review now covers drawing pins. A part with active pins whose
placed program does not cut each pinned contour exactly as the pin's own
emission (re-emitted with the part's cutting settings and matched motion for
motion) warns "Drawing pins not applied", as do locked lead-ins overriding
pins and a pin that no longer matches the geometry; pins switched off are
not reported. The contours that are cut as pinned join locked programs in
the fixed-lead re-check against every part's clean material, and fixed
leads are now also checked against active clamps (Plan Cutting itself does
not model clamps).
AGENTS.md records the fixed-emission safeguard and the characterization
digests.

A drawing-pinned contour is now a fixed emission like a locked program. A
regenerated placement maps its execution motions onto the emitted contour
choices (one group per choice after the program's scribes, opened by its
rapids) and owns as fixed the lead-in, cut, lead-out and tab of every pinned
contour; the rapids between contours, including the one into a pinned
contour, stay the planner's and strictly checked. If the motions do not
split cleanly into one group per choice, nothing is treated as fixed.
So a pinned lead that meets another part's material or its own part's no
longer rejects the candidate: the feasibility precheck accepts a pinned
entry as given, the search keeps it in place, and replay reports a FixedLead
warning naming the part, cutting contour, pin and the part hit, with the
advice to increase spacing or switch off drawing pins for the part. The
plate is UNVERIFIED and needs acceptance; the lead is never shortened and
the entry never moved. The unpinned control and the same plate with pins
off are Ready.

Capture now honours a placement's pins only while they are active: a part
with DrawingPinsOff plans from the plate settings with no warning (D1's
per-part escape hatch), and Part.HasActiveDrawingPins is the shared test.
A pinned part is regenerated like any unlocked part whatever lead-ins or
settings it carried. A locked part with active pins keeps its exact program
and warns "Locked lead-ins override drawing pins on part N; Clear Lead-ins
to apply the pins." instead of being refused; an unlocked part a caller left
ineligible warns that its pins are not applied.
Apply's freshness record now holds each drawing's pin list (reference and an
explicit StateFingerprint of every pin's point, leads and tab) and each
part's pins-off flag, so editing either after capture returns Stale. The
fingerprint writer is shared between settings and pins; a reflection test
pins ContourCutPin's public surface to what the fingerprint covers.

PreparedContours.Capture(program, parameters, pins) takes CutPinResolver
results for the same contours and fixes every resolved pin's contour: its
one and only entry is the pin's point, and it is emitted through the
existing emitter with the pin's own lead-in, lead-out and tab (angle
rounding off, so the entry never moves). Every catalogue returns the pinned
entry alone and emission refuses any other entry for that contour, so no
search path can relocate it. The certified tab size is the pinned outside's
own, so a pinned tab gap is genuine and replay certifies it. Unpinned
contours keep the shared settings and automatic selection; without pins the
existing preparation is untouched (5.1 digests unchanged).
Capture now resolves a regenerated part's drawing pins. A pin that does not
resolve (not on a contour, on several, sharing one, or unplaceable) is never
guessed: its contour stays automatic and the plate gets a FixedLead warning
naming the pin, making the proposal UNVERIFIED. A tab pinned on an internal
contour cannot be cut as pinned (only the outside is tabbed) and warns the
same way. Pins-off, locked parts with pins and freshness follow in 5.4.

D1a (user, 2026-10-14): one locked cutout must not refuse the whole layout.
With confirmed parameters a locked program is now a fixed emission, accepted
as given. The replay checker and the lead validator take a per-motion owner:
a violation inside the fixed emission (a lead meeting another part's or its
own material, a rapid inside the locked program crossing a cut contour, an
uncertifiable tab gap or a partial/reversed/retraced cut) is recorded apart
instead of failing the candidate. The search never rejects or learns an order
rule from them, so fixed emissions never steer it; the planner's rapid into
the locked program and every regenerated lead keep every strict check.
Replay turns those violations into typed FixedLead findings that name the
part, contour and the part hit. A plate whose only findings are these is
BestEffort with IndependentlyReplayed set: never Ready, applicable only with
the per-proposal acceptance, and CuttingPlanService.Apply still rejects it.
Overlap, unreadable programs, stale input and cancellation still block, and
unlocked programs a caller left ineligible and the no-parameter route keep
refusing as before.
Pre-post review now re-checks locked leads against every part's clean
material, so the same violations reappear before posting.
Existing tests that encoded the old locked refusal now assert the warning;
two batch tests that used a locked crossing as their hard block use an
overlap instead. The 5.1 digests are unchanged.

The proposal preview skipped the cut-off overlay: it carries cut-off parts but no
cut-off definitions, so planner cut-offs looked like thin black part outlines
instead of the orange-red dashes used everywhere else. The preview now draws each
cut-off part's own cutting moves in that style.
The same paint guard hid the validation overlay over a preview, so issue markers
for unverified plans were set but never drawn. The overlay now draws on proposals
too, with the marker's part numbers mapped to the preview's proposed order so the
right parts stay highlighted.

Plan Cutting findings dropped the checker's geometry, so selecting one could only
zoom to part extents, and overlap-blocked plates (no preview) did nothing at all.
Findings now keep the check's world-coordinate witness (overlap regions, rapid,
contacts); selecting a row draws it with the Validate Nest overlay, on the proposal
or a blocked plate's live sheet. The witness is excluded from finding equality so
repeated search rejections still collapse to one finding.
The side panel's scrolling report was a wall of text operators skipped. It is now
a colored outcome line, one line for the shown plate, and one remedy or marker
hint above the issue grid, with secondary detail moved to tooltips.

Nests converted from another CAM system carry its seam overcut inside the
clean contour: the last cut runs on past the contour's own start along its
first cut, then a straight jog returns to the start. The ring then touches
itself at its seam, so neither the cutting planner nor the overlap analyzer
could certify it and the whole plate refused.
SeamOvercut recognizes exactly that shape (same line, or same circle and
direction) and trims it from an owned copy; the retraced tail encloses no
area, so material is unchanged and the drawing is never edited. Any other
self-contact still refuses. Arcs of one circle whose centers were each derived
from their own endpoints agree only within Epsilon, so their spans are now
compared at the seam tolerance: shared spans still refuse as overlap, while
arcs that only meet at a joint or lie apart no longer do.
Plates with parts nested in other parts' cutouts then failed to route, since
the host is cut last and every straight approach from the middle of a crowded
cutout crosses a finished neighbour. CuttingNestedOrder tours each host's
inner parts as one run ending beside the host's own contours, hosts follow
the parts beside them, and learned rules still win. Outside entries are
ordered by clear sight lines to the next cut, the look-ahead toward a host is
its nearest contour point rather than its centre, a cutout containing the
arrival point is routed from that point, and a pass that teaches an order
rule ends the round instead of repeating the blocked approach.
Tests: SeamOvercutTests and CuttingNestedOrderTests; the cutting-planning,
diagnostics and overlap tests in OpenNest.Tests pass (1023 passed, 6 skipped).

Report, dialog and diagnostic text across post verification, cutoff

safety guidance, and updated the tests/docs that pinned the old wording.
