Releasing a drawing set makes one nest per material group, so a kit run
spans several nests. The server now records which set revision was
released, the multiplier and the nests it made, so a run can be tracked
across its nests and a nest can say where it came from.
The client uploads every nest first and posts the release last: a failure
part-way leaves ordinary nests and no release, never a release pointing at
missing nests. For the same reason a release is accepted for an older set
revision or an archived set, since the nests already exist by then. The
release id is client-allocated and a nest belongs to at most one release,
so a retried post gets 409 with the release that already holds it.
Releases are append-only and read joined to each nest's current metadata,
so status and deletion are always current. The tables join schema v7, as
the set tables have not shipped yet.

A drawing set is a named list of library drawings with quantities (a kit,
an assembly, a recurring order) that will later be released into one nest
per material. This is the server half: sets get the same revision,
If-Match and archive contract as /api/drawings so the client and tests
follow a known shape.
Schema v7 adds drawing_sets, drawing_set_revisions and
drawing_set_members. Members reference drawings by id and mean each
drawing's current revision, so reads join the current drawing record:
the client can group members by material without one request per drawing,
and the joined record is ignored on save so a read record can be sent
back unchanged. Every change keeps its own member list, and
/api/drawings/{id}/sets answers "used in" from current revisions only.
The drawing query's enum, integer and history-paging parsing is now shared
so both APIs refuse bad input identically.

Nests released from drawing sets need a state before Quote: created but not
yet nested or checked. Draft is appended to NestStatus (value 3) because the
server still accepts integer statuses from existing callers, so existing
numbers must not shift; NestStatuses.WorkflowOrder puts it first wherever the
operator picks a status.
Older desktops read Draft as Quote (the documented unknown-status fallback),
and an older server refuses "draft", so the server must be upgraded before
desktops that can set it.

The pallet-change setting and post doc said M50 moves the cut sheet out,
borrowed from the CL-series manual. Cincinnati's CNC Codes Handbook calls
M50 "Table In" and M51 "Table Out". On the CI Fiber shuttle, Table In brings
the waiting pallet into the laser, which sends the cut one out, so M50 is
still the swap. Say that, note that it expects the waiting pallet to be
loaded, and note that newer Cincinnati samples end without a pallet code.
Default (M50) and posted output are unchanged.
The sample regression fixture now carries each part's pierce, lead-in and
cut moves from the Cincinnati machine program as its saved cutting program.
A new test posts those saved programs without reassigning lead-ins and
requires the program body to equal the sample exactly: L2/L4 macro, G41/G42
side, lead-ins and every cut move (21,911 lines).
Mutation checks: dropping the largest-contour perimeter rule from the kerf
fix fails it at the first perimeter (L4 posted as L2), and forcing G41 fails
it at the first perimeter's G42. The existing tests still replace the saved
programs with OpenNest's own lead-ins first; their comment now says so
instead of describing the sample's leads wrongly.
The CI Fiber post selected G42 for every perimeter. Cincinnati's CNC Codes
Handbook defines G42 as "product remains on the left", and imported
perimeters run clockwise with the part on the right, so the controller
offset every outside edge into the part: parts came out a kerf undersize.
Cincinnati's LaserNST samples only use G42 because they cut perimeters
counter-clockwise.
Winding is normalized only at DXF import, so the post can't assume a
direction either. It now takes the largest contour as the perimeter (as
ShapeProfile does) and picks G41 or G42 from each contour's actual winding.
That also stops a reversed drawing from swapping the L2/L4 lead-in macros.

The safety raise (M47 P<SafetyHeadraiseDistance>) used to fire only when
the next part had a different drawing name, which has nothing to do with
crash risk: a long rapid between copies of the same part got a plain M47,
while a short hop between neighbouring different drawings got the full
raise. Sheets are rarely flat (5/8" plate can be ~1.5" out of flat within
supplier tolerance), and longer rapids cross more of that bow.
Add SafetyHeadraiseRapidDistance (program units, default 12"): any rapid to
the next pierce longer than it takes the safety raise, regardless of
drawing. Unknown travel never does.

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.

Plans every nest on a dedicated OpenNest server (OPENNEST_PROBLEM_NESTS_SERVER)
plate by plate, with a per-plate time limit, and fails when a plate ranks
below the "planning: 1=... 2=..." baseline in the nest's comments. Customer
nests and baselines stay on the server, never in the repository. Refuses a
server holding more than 200 nests, so a production archive is not planned
by mistake.

Console --plan-cutting and MCP plan_cutting/apply_cutting_plan run the
desktop's CuttingPlanBatch: capture, plan, then an all-or-nothing apply.
Settings come from an explicit JSON file or the plates' identical saved
settings, never defaults. Unverified plans need per-call acceptance,
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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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 nest name box was always read-only, so a nest could only be renamed
by Save As, which leaves the old copy behind. In Database mode Nest Info
now edits the name (uploaded with the next Save), as does the saved-nest
browser's Nest Information (saved immediately). File mode keeps it
read-only because the file name is the nest name. Renaming to a name
another active nest already has asks first, and declining reopens the
dialog with the edits kept; a duplicate accepted there is not asked about
again by the nest's first Save.

Nests named offline from the per-PC counter can collide with names already
on the server. Renaming them silently is not an option because the name may
already be on posted CNC programs and labels, so the first Save of a nest to
a server now checks for an active nest with exactly the same name and, only
then, offers a freshly allocated name in an editable dialog (Cancel saves
nothing). A failed or slow check keeps the current name, as before. Save As
and pending-upload reconciliation are unchanged.

File > New restarted its counter every day while names only carry the
year, so the first nest of each day was always N26-223, and each PC kept
its own counter. In Database mode the nest server now hands out the
year's next number (POST /api/nest-names/next, nest_sequences table,
schema v6), staying above every stored generated name so offline or
pre-existing names are never reissued. The per-PC counter remains the
fallback when the server is unreachable or older, resets per year, and
is raised past each server allocation.

Clamps could only sit on the origin-side edge and be edited as a list in
Nest > Clamps. Setting them up against a real sheet is easier by dragging
them where they are, so Plate > Edit Clamps adds an edit mode: drag a clamp
along its edge or onto another edge, click near an edge to add one, click a
clamp's locating dimension to type its distance from the origin, Delete to
remove. Dimensions measure to the clamp center or its near edge
(remembered per user). Edits replace the nest's rail so every sheet follows,
like the dialog.
Rail clamps now carry a ClampEdge (origin side, far side, origin end, far
end), positioned from the origin along that edge. Origin-side clamps keep
their ids and files; other edges persist in optional per-edge arrays in
.nest files and clamps.json, omitted when empty.

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.

Part sub-program calls restored the sheet frame with G92 at the part
corner while the tool sat at the sub-program's last endpoint, shifting
every later part. The call now raises the head, rapids back to local 0,0
and restores there. Parts share a sub-program only when their posted
toolpaths match, so per-part lead-ins are kept.
Suppressed moves are left uncut: the cut resumes with a rapid past them.
Head raises go before the rapid that leaves a feature, one per rapid:
the safety raise now precedes the rapid to a new part instead of
following its first feature, and sub-program mode no longer posts M47
then M47 P2000. M47Mode.Auto posts M47 before rapids longer than
M47OverrideDistanceThreshold and /M47 otherwise. ExteriorM47 applies to
the contour spanning the part's cut extents.
The sheet GOTO targets FeatureLineNumberStart and is omitted without line
numbers. PrepareForNest pre-selects only the gas- and thickness-matching
library. Part programs are read through absolute copies, never switched
to absolute in place.
Removes the unimplemented UseSheetSubprograms, CoordModeBetweenParts and
ProcessParameterMode (G89Mode); old configs still load.

Validate Nest, the posting review and console --post now report a
"Part spacing" finding for pairs of parts that do not overlap but sit
closer than the plate's part spacing. Before, only Auto Nest's
Keep/Discard review checked spacing, so hand-edited layouts could be
validated and posted with parts too close together.
Candidates are found with Auto Nest's own outline test, moved into Core
as SpacingOutline (NestLayoutCheck and NestTolerances now use it; Engine
tests unchanged). Because that outline circumscribes arcs by more than
the spacing slack, each candidate is confirmed on native contours
flattened 20x finer than the slack, so arcs placed exactly at the
spacing by interactive fills stay clear. The finding reports the
measured gap and marks the middle of the closest approach. Overlapping
pairs, cut-offs, zero spacing, the plate edge and clamps are not
reported as spacing findings.

With a pierce diameter set, a perimeter none of whose configured lead-ins keeps its pierce
clear (a lead shorter than the zone radius, or neighbours closer than it) was only rejected.
Plan Cutting now looks for a pierce in the open scrap around the part instead.
- ScrapPierceSearch (Engine): the window four zone radii around the part, minus every nearby
part's clean material grown by the zone radius and a margin (ClipperBridge, conservative
flattening); the clear point nearest each ranked perimeter entry is a candidate. Other
parts' cutouts count as scrap, the part's own holes do not. With no clear scrap, the
PolyLabel pole of the free scrap is the best effort, and its shortfall is reported.
- ContourChoice.Pierce / PreparedContours.ScrapPierceEntry: the planner's choice carries the
pierce; the emitter cuts a straight lead from it to the nearest perimeter point and still
reads nothing but the contour and the choice.
- Every candidate passes the lead validator like any planner-chosen entry; pinned perimeters
keep their pins and warn. Without a pierce diameter nothing changes.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Thick plate pierces leave a crater wider than the kerf. CuttingParameters.PierceDiameter
(Cutting Settings > Pierce Diameter, 0 = off) requires every lead-in pierce to keep half
of it from all part material: its own contour, its holes and every other part.
- LeadPathValidator checks the zone during Plan Cutting candidate checks and final
replay; fixed emissions warn as usual. No-fit findings explain the zone.
- PierceZoneReview reports Pierce zone warnings before posting for leads from any source.
- Holes whose configured pierce is inside the zone move it toward the hole's PolyLabel
pole (round holes: the centre), as close to the contour as the zone allows; a hole
too small for the zone is pierced at its pole and the shortfall is still reported.
- Straight corner leads and round-hole clamping use the larger of PierceClearance and
the zone radius. The manual lead-in preview shares the Core rules.
- Persisted through the DTO, owned copies and state fingerprint.
Perimeter fallback is not included; see docs/geometry/pierce-zone.md.

- POST /api/nests with an existing id (active or deleted) now returns 409 with
the current record instead of a 500 from the UNIQUE constraint.
- Uploaded nest metadata must have string text fields and a defined status;
null fields and undefined statuses (e.g. 99) are 400 instead of a 500 or a
stored invalid value.
- --database <path> is accepted alongside --database=<path>; a missing or
repeated path fails startup instead of silently using OPENNEST_DB/default.

Hole sub-programs are stored incremental but were written under G90 as
if absolute, producing invalid arcs. The registry now posts absolute
copies and leaves the nest's programs untouched.
Sheet-level hole calls omitted the part location from G52, so every
part's holes were cut near the sheet origin. Calls now shift to the
part location plus the hole offset.
Hole calls were matched to sub-programs by call id, which planned
emission numbers 1, 2, ... per drawing, so holes from different drawings
shared the first drawing's sub-program and diameter. Calls are now keyed
by program reference and deduplicated by posted toolpath.
A part opening with a hole call got a synthetic rapid that posted an
empty pierce on the part edge. The rapid is now only inserted before a
contour motion with no rapid ahead of it; the hole call carries the
part comment and safety head raise that feature used to hold.
The sheet writer re-sorted parts bottom-then-left with cut-offs last.
Plate order is the cut sequence, so parts now post in plate order.
Regression tests replay the posted G-code for off-origin parts of
several drawings and check each hole's center and radius.

Desktop Auto Nest's "Best plan so far" strip now fills in for every built-in
whole-job engine except FlatBar, not only Irregular.
- Rectangles makes one sheet-by-sheet run, so it reports the finished job as
its one plan, then replays its plate commits (token checked as before).
- Circles reports when a stock-preference run or a tail re-plan beats its
best result so far.
- Default scores each candidate plan as it ranks results (valid, fewest
unplaced, lowest cost, candidate order) and reports it only when it beats
every plan already shown, so a later candidate never shows a worse plan.
The chosen result is always the last plan reported.
- Shared ReportPlan/SameLayout helpers on CandidateProgress; Irregular uses
them too. Reporting never changes the search.

Auto Nest no longer draws parts on the plate view before they are kept:
its result is a set of sheets, possibly of several sizes, not parts on the
current plate. Ghost parts stay with interactive Fill and remnant tools.
- NestJobStage.PlanImproved carries an engine's best whole-job plan so far;
Irregular reports one whenever a variant or the tail re-plan beats it.
- NestPipeline adds PlanSheets: the plan on detached drawings built from
the job geometry (with the caller's names and colors), so previews never
touch caller drawings or quantities.
- SheetStripControl draws every sheet side by side at one scale, repeats
once with their count, captioned with size, parts and utilization.
- The progress window shows "Best plan so far"; a review window shows the
final sheets, totals, cost summary and unplaced parts before commit.

NestProgress gains PreviewSheet, a detached plate for the stock the preview
parts lie on; Irregular builds one per stock. PlateView draws it (size, edge
spacing, clamps) in place of the plate while the preview is shown and drops
it whenever the preview is cleared or the plate changes. Auto Nest zooms out
when a trial sheet falls outside what it has already shown.

The frontier packer reports its placements after each choice; the engine
turns them into preview parts at most four times a second and sends them as
NestProgress.BestParts with the stock work area, which desktop Auto Nest
already draws on the plate view. Reporting only reads finished placements,
so layouts are unchanged with or without a progress sink.

Every Auto Nest run, and every Default-engine run, recomputed each part's
best-fit pairs: job snapshots are fresh objects and BestFitCache keyed
its entries on Drawing reference, so the Irregular engine paid
PairCatalog.Build (about half of a 118-part solve) on every run of the
same drawings.
BestFitCache now keeps a process-wide, bounded (512 sets, least recently
used first) pool of unfiltered candidate sets keyed by the exact content
of a PartGeometrySnapshot (mode and every motion value, bit for bit;
PartGeometrySnapshot.ContentComparer) and the spacing. Every drawing
DrawingJobMapper.CreateDrawing reconstructs from a snapshot declares
that geometry (BestFitCache.ShareByGeometry), so the Irregular pairs and
blocks, the cutout lattice and the Fill/Default job paths all read and
fill the pool. Candidates depend on the program geometry and spacing
alone, so a pooled set is the set the search would produce: benchmark
layouts, costs and placements are unchanged on the synthetic nests (all
engines) and on the 67-drawing, 118-part job. Failed searches are not
pooled, Invalidate leaves the pool alone, Clear empties it, and a
drawing whose Program is replaced stops vouching for its geometry.
Same 118-part job solved twice in one benchmark process (--parallel 1):
the second solve now takes 13.1 s after a 33.0 s first; before, 35.6 s
after 41.8 s.

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.

Rotated imported arcs whose start and end radii differ by ~5e-11 are
converted without refitting their centre, so their rebuilt start point
lands just outside the cached part bounds. The allowance scaled with
coordinate magnitude (4096 steps, ~2.9e-11 here) and rejected them,
which stopped Plan Cutting's "Add scrap cut-offs" with "Converted
material extends outside cached part bounds". Use the existing 1e-10
cap as an absolute allowance; larger mismatches still block planning.

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 67-drawing, 118-part job took about six minutes through the desktop
Auto Nest path and was cancelled before any layout appeared. Almost all
of it was the cutout pre-pass, the rest the Irregular engine.
Cutout pre-pass (317 s -> 8 s on that job, same bundles and poses):
- The lattice and NFP searches prepare the frame's and the occupants'
validation outlines once per search (NestLayoutCheck.Prepare) instead
of re-outlining and re-triangulating the frame at every candidate, and
test candidates against the small occupants before the frame. Answers
match the pairwise check exactly, including its leftmost-inflated rule.
- A hole's proposal is replayed for the same frame, hole and offered
inserts: automatic-rotation inserts ask the same question at every
frame angle.
Irregular engine (40 s -> 15 s, benchmark 42 s -> 19 s, same layouts):
- Concave no-fit polygons are built as the union of pairwise convex sums
of each footprint's convex pieces (ear clipping plus Hertel-Mehlhorn
merging on the Clipper lattice) instead of n*m edge-pair quads; a
footprint that cannot be decomposed keeps the old sweep.
- Pair and block catalogs share one private drawing per part geometry,
owned by the engine instance, so each part's best-fit search runs once
per instance and across a pipeline's trial and ordinary solves.

when the scheme changes; custom colors keep their palette slot.
- Library settings store a color only when it is custom.
- Document drawing colors in nest-file-format.md and nesting-view-colors.md.

- Add the Blueprint scheme: navy canvas, pale blue sheet, dark navy part
outlines, orange-red rapids and twelve distinct, readable part fills.
- Use it as the settings default and the fallback for unknown scheme names,
and list it first in Options. Saved scheme choices are kept.
- Run the palette spacing and readability tests over Blueprint and Classic.
- Document the default in nesting-view-colors.md.

The Clear Lead-ins & Cut-offs button stays enabled during planning.
Confirming cancels the running plan, clears once the cancellation lands
so the plates never change under the planner, then replans.

The nest report PDF gains an estimated cut time: the job total on the
summary, an Est. cut time column in the plates table, and per-plate and
all-copies times on each plate page. Times come from the cut simulation
with the settings last used in Calculate Cut Time, plus clamp removal.

The cut simulation treated Display-layer contour moves (what cutting
strategies emit) as head-up travel, so plates with assigned lead-ins were
timed as rapids. They now cut, matching the verifier and posts, and
suppressed moves are left out.
Cut time now follows the CI Fiber post: closed clockwise contours and
cut-offs take an outside feed, other contours a hole feed, and etch-only
contours can be skipped like its SkipScribe default. The settings are
shared by Calculate Cut Time and the simulator, and plate/nest times now
always come from the simulation.

A Grbl-style lookahead planner re-times the cut simulation with
trapezoidal acceleration, junction-deviation corner speeds and a
centripetal cap on arcs. Machines gain cut/rapid acceleration and corner
deviation in Machine Configuration, with placeholder values until the
controller's are entered. The simulator and Calculate Cut Time pick the
machine (or full speed), and the simulator shows the live head speed.

Profiling the cutout pre-pass on real round-part jobs put ~97% of its time in
the frame-wall NestLayoutCheck.Clears inside CutoutCirclePacker.Fill. Ear-clipped
round frames make every perimeter/insert triangle pair overlap, so a clear pair
runs hole subtraction for every pair. The same question repeats for every frame
angle and repeated frame instance, because Automatic inserts get identical
frame-local poses.
- CutoutMemo, one per Prepare, replays geometry reads, circle items and Clears
answers. Keys hold geometry by reference, pose bit patterns, argument order
and spacing. It is threaded through CutoutCirclePacker.Fill and the router's
round-only path.
- TriangulatedRegion.SubtractAllHoles measures each piece's bounds once, skips
holes and hole triangles that no piece reaches, and ping-pongs the remainder
between scratch buffers instead of copying it into pooled ones. Clip
arithmetic and order are unchanged.
Bundles are byte-identical on 14 real and 10 synthetic ring jobs. Pre-pass time
over the real set drops from 99.6 s to 10.1 s (N0414-02 35.8 s -> 0.6 s).
