Core PlateRemnant.Expected picks a full-span cut-off drop clear of the
parts (less kerf, nominal position for head-locked overcuts), else the
largest salvage edge offcut, else none below the nest's new persisted
MinimumRemnantDimension. NestJobCost's salvage offcut now calls the Core
rule unchanged. NestWriter writes a derived plate expectedRemnant that
readers skip, and /sheets reports it per plate.

Auto Nest on MaterialLedger stock now records which inventory item each
physical sheet uses, so ML can hold exactly those items instead of matching
by size.
- Core: Plate.StockItemCodes (entry i = sheet i of Quantity; empty = uncoded).
Core invalidates it: a resize clears it (turning the sheet keeps it), a lower
Quantity truncates it, a nest material/grade/thickness change clears every
plate's, ClearAll clears it and new plates never copy it.
- Desktop Auto Nest: after a kept proposal is committed, LedgerStockAssignment
deals each ledger row's codes to its plates in Nest.Plates order (bundles
repeat their code; clamp-removal variants use their base row). Rejected,
discarded or cancelled proposals never reach it. NestPipelineCommit.PairWithStock
pairs committed plates with their solved stock; the engine stays ledger-free.
- Plate list tooltip: "Stock: CODE (location)"; locations are display-only.
- nest.json: optional plate stockItemCodes, omitted when empty, read leniently.
- /api/nests/{id}/sheets: new plates[] { index, width, length, quantity,
stockItemCodes }; sheets[] unchanged.

Full circles now take InternalLeadIn/InternalLeadOut like every other
cutout; the ArcCircle lead settings and the cutting panel's Arc / Circle
tab are removed. Circle-specific geometry handling (radius clamp, angle
rounding, pierce zone) is unchanged.
Older nest files and desktop settings still load: their arcCircleLeadIn/
arcCircleLeadOut keys are ignored and no longer written, so re-planned
circles take the internal leads. Saved part programs are untouched.

Drawing Sets > More > Import BOM reads a BOM and its drawing folder,
matches each drawing to the library by its D4 identity and geometry
(reuse, new revision, or new drawing) and opens the set editor with a
new set prefilled with the BOM quantities. Reading only queries the
library; Create Set lists the uploads and revisions and asks before
storing them, and the set is stored only by the editor's Save.
Parts with no material or thickness still import and are flagged for
Edit Drawing. DrawingPackage.GeometryKey compares geometry independent
of the fresh entity ids each DXF import assigns. In Database mode File >
Import BOM opens this flow instead of creating nests directly; File mode
is unchanged.

Slats are strips of a set thickness running the full length or width of
the table, one every pitch. A part's contacts are the corners of where its
material crosses a slat, so the support check and support tabs work as on
the grid. Nest > Support Bed... picks grid or slats; nest files store
type "slats" and support-grid.json keeps both layouts' values. Draw
Support shows the slats cut off to the sheet.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The support grid was one shared support-grid.json, off by default, and a nest
had no machine at all, so a plasma table and a fiber laser could not have
different grids, and nothing could pick machine-specific behavior later
(lead-ins differ between laser and plasma; tabbing depends on the grid).
- Nest.Machine (id + name) persists as top-level `machine` in nest.json;
malformed values load as none.
- MachineConfig.SupportGrid holds each machine's grid; a machine without one
still falls back to the legacy support-grid.json.
- New and BOM import assign the Tools > Nest Defaults machine (first by name
when none is chosen) and give the nest that machine's grid.
- Nest > Machine reassigns a nest and swaps in the new machine's grid;
Nest > Support Grid saves machine defaults to the nest's machine.

Stock can arrive up to 1.5 in wider than nominal, so only the origin-side
edge is certain. A cut-off with a head-locked overcut cuts past the nominal
far edge with the head height locked, covering the oversize. With that lock,
Plan Cutting may start the far-edge segment at the far edge: overcut outward,
rapid back still locked, unlock, cut toward the origin. Without it the
direction stays fixed, as decided in Project Memory a20ea455.
- CutOff.HeadLockOvercut / FarEdgeFirst, persisted in .nest; HEAD HEIGHT
LOCK/UNLOCK comment markers; far edge is quadrant-aware.
- Planner offers the reversed far-edge segment in the joint search, the
safest route and segment insertion; Apply records the direction.
- Cincinnati CL and CI Fiber posts gain lock/unlock code settings and refuse
head-locked cut-offs while either is empty.
- Automatic cut-off dialog setting (off by default, 1.5 in), kept between
sessions and used for new cut-offs.
Lock codes and machine behaviour with the head locked are unconfirmed.

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.

Saved best-fit pairs are in the drawing's canonical frame, but the canonical
angle is recomputed on load and was not saved with the set. When that
computation changes (RotatingCalipers checking every hull edge, marks no
longer counted as material), old pairs were replayed in a turned frame and
could overlap.
Each saved set now records canonicalAngle, and BestFitCacheStore.Import
skips sets whose angle no longer matches the recomputed one (1e-9 rad,
modulo a full turn). Sets from older files have no angle and are dropped;
their pairs are recomputed when next needed.

Model the machine's support bed as a grid of contact points measured
from the plate origin, and check each part's center of gravity against
the convex hull of the grid points under its material. The bed is
extensible so straight and CAD-imported curved slats can follow.
- Core: SupportBed/SupportGrid, SupportMaterial and SupportAnalyzer
(margin with registration tolerance, best single tab point)
- Nest-wide support bed that every plate follows, saved in
plateDefaults.supportBed; machine defaults in support-grid.json
- CuttingParameters.SupportTabs: Plan Cutting tabs only unsupported
parts and limits their perimeter entries to points where the tab
steadies the part, falling back to any fitting entry
- Desktop: Nest > Support Grid..., View > Draw Support overlay and a
"Tab parts the support grid cannot hold level" tab option
- docs/support-tabs.md, nest file format and planner notes

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.

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.

- Add Drawing.HasCustomColor, set when a color is picked in Drawing
Properties or comes from a library record with a stored color.
- Persist it as customColor in .nest files (omitted when false) and keep it
out of drawing packages; split pieces inherit it.
- Recolor non-custom drawings from the active palette when a nest opens and
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.

Select entities in the CAD converter (click, or drag a window/crossing
box) and right-click to exclude/include them or set them to cut, etch or
display only, regardless of their DXF layer. Delete excludes the
selection.
Roles are stored per source entity on the drawing and persisted in the
entity set as an optional `roles` map. Display-only geometry is kept out
of the program, so posts, nesting and verification never see it; placed
parts draw it as a dashed overlay. Load-time scribe repair skips
etch-layer entities set to cut. Per-entity exclusions now survive filter
changes.

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.

Schema v5 stores each distinct drawing package once in drawing_packages,
keyed by SHA-256; revisions point at it, so details, settings, archive and
restore revisions add no blob. The v4 drawing tables are replaced outright
(no production library existed); nest tables are untouched.
Nesting settings (cut first, priority, rotation constraints, color) become
structured record fields (DrawingLibraryRecord.Settings), returned on every
read, filterable by cutFirst, editable through the metadata endpoint and
applied by LibraryDrawingInsert. Canonical packages now leave every
record-owned field at its default, so renaming or changing settings never
changes the package hash. Saving a nest drawing to the library carries its
settings into the record.
The desktop library browser gains a Cut first column and an Edit Settings
dialog that saves notes and settings as a new revision with the same package.

Drawings flagged CutFirst (e.g. test squares) are sequenced ahead of
every other part: they get their own route with the chosen method, then
the remaining parts follow. Cutoffs crossing a cut-first part still
precede it. The flag is editable in Edit Drawing, persists in .nest as
`cutFirst` (omitted when false) and is kept by split pieces.

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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Forming backgauge tabs drawn as open cuts came off the sheet loose and could not be
planned. A breakoff merges the scrap into the outline and cuts the shared edge as
closed slots between tabs, so it stays attached and every pierce lands in scrap.

Drawing cut pins and the per-placement pins-off flag now survive
save/reload and travel in drawing packages.
- `DrawingDto.cutPins` reuses the plate cutting-parameter lead and tab
DTOs. Pins are read strictly per entry: an unknown lead or tab type is
never replaced by a default, because a pin that cut differently from
what was saved is worse than no pin. A bad entry is skipped with a
reader warning naming the drawing and pin, and the rest load; a value
that is not a list loads no pins, with a warning. A nest never fails to
open over pins.
- `PartDto.drawingPinsOff` is written only when true. Anything other than
a boolean loads as pins on (the drawing wins, D1) with a warning naming
the plate and part, so an operator's override is never lost silently.
- Packages carry pins as drawing content, so pinning a drawing changes
its package hash and the newer-revision notice can tell geometry/pins
changes from detail-only ones.
- `Part.DrawingPinsOff` holds the flag; nothing plans with it yet.

A nest drawing copied from the drawing library has to remember exactly which
revision it is a copy of, so later slices can tell when the library moved on
(D2b) and so a save can target the right drawing. `Drawing.Library` holds the
server key, id, revision and a snapshot of that revision's cut type, thickness,
material, grade, units, notes and package hash. It is immutable, so copies can
share it.
`DrawingDto.library` is additive and omitted when null. It is read leniently:
anything that cannot be trusted as a link drops the link with a reader warning
and the drawing still loads, because a nest must never fail to open over
provenance. Enum names are checked as single names since Enum.TryParse would
accept numbers and comma lists.
Copy paths: converter edits update drawings in place and so keep the link;
canonical engine copies carry it; split pieces are new geometry and get none.
Packages strip it so linking never changes a drawing's package bytes or hash.

The bestfits/ archive entry was undocumented. Describe its JSON shape,

Operators sometimes pull a clamp for a manual layout, but only Auto Nest's
last-resort search could take clamps off a sheet. Right-clicking a clamp in
Select mode now offers to remove it from that sheet or put it back, reusing
the existing per-sheet RemovedClamps, so the zones, cut-time charge, display
and .nest persistence all behave as they do for Auto Nest removals.
The change is refused while a nest run or fill may be reading the clamps,
sharing the guard the Clamps dialog already used.

PEP-converted nests stored etch marks only in each placed part's locked
cutting program; the drawing program held the contour cuts alone. Because
Remove Lead-ins rebuilds a part from its drawing, clearing lead-ins also
erased the marks from every part.
Recover the marks while reading the nest: when a drawing has no scribe
moves and every placement that kept its saved program carries the same
marks, add them to the drawing in its own frame and refresh that drawing's
clean placements. Saved programs are never rewritten, drawings that already
have marks are untouched, and drawings whose saved programs disagree are
left alone rather than guessed at.
The writer omitted an empty rail sheet when its size, quadrant and zones
matched the defaults, ignoring spacing, so a sheet left at the old part or
edge spacing after a defaults change (configured stock under C17) was
dropped on save. The comparison now includes edge and part spacing.
PM 455f6763-f0aa-40da-b9ad-11de4b2ea95b
Commit can attach the stock's rail to a sheet whose nest has no (or another)
default rail, but only the default rail was saved and the reader re-attached
sheets only to it, so the removed clamp and its time vanished on reload. A
sheet following a rail other than the default now saves it in an optional
per-plate clampRail (read leniently, omitted otherwise), and the reader
re-attaches the sheet to it.
PM 22daec3d-dabb-4aae-95f7-c1d090d5dcdf
Changing the nest defaults (Nest Info, Set as default, Edit Plate on an
empty sheet) left the editor's trailing empty sheet on the old size and
quadrant, so the writer's clamp-preserving empty-sheet rule saved it as a
stale extra sheet. PlateManager.ChangePlateDefaults wraps a defaults edit:
a trailing empty, cutoff-free sheet that exactly matched the old defaults
(and followed their rail with no removed clamps or explicit zones) takes the
new defaults; every other empty sheet keeps its configuration and is still
written.
PM cade6901-5f4a-4503-85bf-0ea681d9ca7f
Every plate was written with "removedClamps": [], so files without the
feature changed. The key is now omitted unless a clamp was removed, like
the other additive sections; nest-file-format.md documents removedClamps
and removalMinutes and their lenient reading.
PM 6ded8ac4-84fd-4e8b-9a3b-6f41e494542c item (c)
A clamp is an avoidance area, so a clamp that only partly reaches a
sheet (for example centered at 60.5" on a 60" sheet, or near the
origin) now keeps its whole 1.5" x 0.625" footprint instead of being
clipped to the sheet; clamps wholly beyond the sheet are still left
off. Job validation accepts a zone that hangs past the sheet edges and
still rejects one that does not reach the sheet at all. Both packing
lanes already block keep-outs extending past the bin; a hanging-clamp
solve through Rectangles, Irregular and Default keeps every part clear
of the whole inflated footprint.
User decision 2026-10-12, settling the plan's pending D2 question.
The empty-plate rule drops a rail-following empty sheet only while it
still matches the plate defaults; a trailing sheet created before the
defaults changed is written. Say so instead of promising that the
editor's trailing sheet is always dropped. Comment and documentation
only; behaviour unchanged.
Delta review minor finding, Project Memory 4e5f566d.
Omit an empty clamp-carrying plate only when a new plate from the saved
defaults would recreate it: same size and quadrant and zones the saved
rail recreates. A rail-following empty sheet with another size or
quadrant is written again instead of being lost.
Read plateDefaults.clampRail through a lenient converter so a wrongly
typed rail (a string or null width, non-numeric centers, an array in
place of the object) loads as no rail while every plate's saved zones
still load, as the file format documents, instead of failing the whole
nest.
Review findings 4 and 5, Project Memory 4e5f566d.
Write the nest's machine clamp rail under plateDefaults.clampRail
(width, depth, centers) so plates created or resized after a reload
still get the clamps. The key is omitted for nests without a rail, and
a missing, empty or malformed rail loads as none while each plate's
saved zones still load.
On load a plate follows the rail again only when its saved zones are
exactly the rail's for that sheet; other zones are kept as written.
The empty-plate filter now drops an empty sheet whose zones the saved
rail recreates, so the editor's trailing empty sheet is not written
for every clamped nest; empty sheets with other zones are still kept.
Add the additive per-plate clamps array (id, x, y, length, width) to the
nest DTO with writer and reader support. Files without the key load with
zero zones; an individually malformed entry is dropped while the rest of
the nest loads. A plate carrying only clamp definitions now survives the
writer's empty-plate filter; genuinely empty plates remain omitted.
Format documented in docs/nest-file-format.md.
Add NestStatus (Quote/ToBeCut/HasBeenCut) plus MadeBy on Nest, written as
additive camelCase nest.json fields with PascalCase enum strings matching
the units convention. Legacy files and unknown status values fall back to
Quote. The nest info dialog gains a Status dropdown and Made By box.
