The console overlap check and the MCP check_overlaps tool counted
crossing points, so a part contained in or stacked on another reported
no overlap. Both now list pairs from PartOverlapChecker.FindOverlappingPairs,
which uses the Intersects verdict and skips cut-off parts.
Plate.HasOverlappingParts stays for now: two test files outside this
change still call it.

The multi-phase fill strategy has been named Lattice since the engine
rename, but the console's --engine help and the MCP tool descriptions
still offered it as Fill. Fill keeps working as an alias.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
"Fill" said nothing about what the engine does, since every engine fills.
It is now Lattice, and Fill stays an alias, so saved selections, scripts
and API requests keep working. Engine descriptions are rewritten in plain
language and shown beside each name in the desktop engine lists; the main
toolbar's tooltip also says when Fill Area falls back to Lattice.
Docs also cover the leftover placement from the previous commit.

Customers and design tools hand over SVGs, and getting them in meant a
trip through another CAD tool. CadImporter now reads them like any other
drawing, and plates, programs and converter entities can be written out.
An SVG's numbers are not drawing units, so import converts to the nest's
units and never guesses: only an absolute width or height counts as a
stated size, since px means 1/96 in to browsers but 1/72 in to
Illustrator. Without one the desktop asks, showing the size each choice
gives, and headless callers must pass the scale or the import fails.

The repo mixed variants such as center/centre and color/colour, so a
name could be spelled either way and searches missed half the hits.
Standardize on the US spelling, matching .NET's own APIs (Color, Center).
Wire values owned by other systems keep their spelling: the material
ledger's "Cancelled" hold status and GitHub's "cancelled" job status.
No behavior change beyond the spelling of a few status messages.

PlateFillService throws for a plate with a sheet outline, but the desktop
swallowed it: Fill (Ctrl+F) caught every exception and showed nothing, and
Fill Area's async void either completed silently or let it escape.
PlateFillService.Refusal(plate) names the reason, and every caller checks
it first: Fill and Fill Area put it in the status bar and add nothing,
Pattern Tile offers a new plate only, the MCP fill/pack tools return it as
an Error result, and the console exits 2 with it unless --autonest is given.

Every whole-job engine chooses among the offered stock sizes, and on the
synthetic benchmark nests Default matched or beat StockLadder on all 18
runs (saved sizes, a six-size pool, with and without salvage credit),
costing 30-40% less in total with mixed sizes. Its sheet-swap step never
produced a win over Irregular's tail re-plan.
The registry maps "StockLadder" to Default so saved selections, scripts
and API requests keep working. OrderedPlateNester stays: Fill and the
remnant strategies use it for restricted rotations, and its golden layout
is now pinned through NestJobRunner with the parts requested largest
first, as StockLadder requested them.

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.

Circles packs every part as its minimum enclosing circle at centers tangent
to two of the work-area walls, placed discs and clamp keep-outs, bottom-left
and left-bottom, with hexagonal and square lattice seeds. It bids only when
every part fills at least 0.8 of its enclosing circle and otherwise returns
everything unplaced at once. Default runs it as a third candidate.
Rectangles' sheet-by-sheet stock loop moves to NestingEngines/SheetByStock
(Rectangles output unchanged) and Default's candidate scoring and commit
forwarding become shared helpers. Circles also runs the whole job preferring
each offered stock and keeps the best result. Contract tests take shapes an
engine can override.
Synthetic round jobs, salvage-credited: Circles wins or ties all six with
valid layouts; Default cost falls about 4% versus Irregular alone.

NestPipelineResult.Unplaced lists each requirement's unplaced copies with a
typed NestUnplacedReason, counted from the returned placements: no stock fits
at the sampled rotations, reserved in a cutout of an unplaced frame, stock
exhausted, plate limit, no position found, or proposal not keepable. Desktop
Auto Nest, Console --autonest and MCP autonest_plate/autonest_job report them;
the API returns NestResponse.Unplaced, persisted from response schema 5.

Console and Mcp each re-derived whether a name was a fill strategy, a
whole-job engine or unknown. EngineNameResolver now owns that decision,
trims consistently and accepts renamed legacy engine names; front ends
keep their own message wording.

Reading a nest used to fill the engine's static BestFitCache as a side
effect, which is the only reason OpenNest.IO referenced OpenNest.Engine.
Core now defines SavedPairSet/SavedPairResult and IBestFitStore; the
mapping to BestFitResult moved verbatim into Engine's BestFitCacheStore.
NestReader/NestWriter take the store as an optional BestFitStore property
and skip bestfits/ entries without one.
Every production reader and writer opts into BestFitCacheStore.Shared, so
behaviour is unchanged; the golden round-trip test still matches byte for
byte.

The MCP server uses no Windows APIs, so net8.0-windows only kept it from
building on Linux. Floating 0.*-* / 9.* versions let a restore silently pick
up a new ModelContextProtocol preview; pin the currently resolved versions.

The engine argument's description now names every built-in engine with what
it suits, so a model can choose one; omitting it still means Default. The fill
tools resolve an omitted strategy to Fill directly instead of through the
session's whole-job default. Front-end tests cover the MCP and console
defaults and keep the description in step with the registry's built-ins.
The multi-phase lattice fill (linear, pairs, rectangle best-fit, remainder) is
no longer meant to be the engine used by default, so it gets a name for what
it does. The registry lists it as Fill and maps the old name Default to it;
PlateFillService, PlateNesterFactory and NestJobOptions use Fill, and every
fill-strategy caller still accepts Default. Console --autonest now validates
engine names through NestingEngineRegistry.ResolveName so renamed names work.
Layouts are unchanged: Default and Fill resolve to the same fillers and the
golden layouts pass under the new name.
.mcp.json pointed at C:/Users/AJ/.claude/mcp/OpenNest.Mcp/run.cmd, a
profile path and wrapper script that only existed on one machine, so the
server failed with CONNECTION_CLOSED everywhere else. Launch the published
exe via ${USERPROFILE} instead.
Also route console logging to stderr: the host's default console logger
wrote to stdout, interleaving log lines with the JSON-RPC stream.

Console --engine now names a jobs engine for --autonest (solved once
through NestingEngineRegistry.Create and committed onto the plate) or a
built-in fill strategy for single-plate fill through the public
PlateFillService; unknown names exit with the valid choices instead of
consulting the process-global legacy registry. MCP nesting tools take an
explicit engine argument per call with the session default, never read
process-global active-engine state, and reject whole-job engine names on
single-plate fill tools. NestingEngineRegistry gains an explicit Create
(name) resolution; PlateFillService gains a public ResolveStrategy and a
plate-number Nest overload used by interactive callers.
Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
Consolidated two stateless classes into one unified API: Dxf.Import(),
Dxf.GetGeometry(), Dxf.ExportPlate(), Dxf.ExportProgram(). Export
state moved into a private ExportContext. Removed bool+out pattern
from GetGeometry in favor of returning empty list on failure.

Drawings created by BomImportForm and MCP InputTools were missing color
assignments, causing them to render with default empty color instead of
the standard part color palette. Moved PartColors and GetNextColor() to
Drawing in Core so all consumers share one definition.

Material and thickness are properties of the nest (all plates share the
same material/gauge), not individual plates. This moves them to the Nest
class, removes them from Plate and PlateSettings, and updates the UI so
EditNestInfoForm has a material field while EditPlateForm no longer shows
thickness. The nest file format gains top-level thickness/material fields
with backward-compatible reading from PlateDefaults for old files.

Etch marks for up bends are now real geometry entities on an ETCH layer
instead of being drawn dynamically. They flow through the full pipeline:
entities → FilterPanel layers → ConvertGeometry (tagged as Scribe) →
post-processor sequencing before cut geometry.
Also includes ShapeProfile normalization (CW perimeter, CCW cutouts)
applied consistently across all import paths, and inward offset support
for cutout shapes in overlap/offset polygon calculations.

Add toggleable pierce point drawing to PlateView that shows small red
filled circles at each rapid move endpoint (where cutting begins). Wire
through View menu, EditNestForm toggle, and MainForm handler.
Also rename RectangleShape/RoundedRectangleShape Width/Height to
Length/Width for consistency with CNC conventions, update MCP tools and
tests accordingly. Fix SplitDrawingForm designer layout ordering and
EntityView bend line selection styling.

PolygonHelper.ExtractPerimeterPolygon always used OffsetSide.Right
assuming CCW winding, but DXF imports can produce CW winding. This
caused the spacing polygon to shrink inward instead of expanding
outward, making parts overlap during nesting.
Now detects winding direction via polygon signed area and selects
the correct OffsetSide accordingly.
Also adds save_nest MCP tool and a BOM-to-nest builder utility
(tools/NestBuilder) for batch-creating nest files from Excel BOMs.

Move fill algorithms to OpenNest.Engine.Fill namespace:
FillLinear, FillExtents, PairFiller, ShrinkFiller, Compactor,
RemnantFiller, RemnantFinder, FillScore, Pattern, PatternTiler,
PartBoundary, RotationAnalysis, AngleCandidateBuilder, and
AccumulatingProgress.
Move strategy layer to OpenNest.Engine.Strategies namespace:
IFillStrategy, FillContext, FillStrategyRegistry, FillHelpers,
and all built-in strategy implementations.
Add using directives to all consuming files across Engine, UI,
MCP, and Tests projects.

The auto-nest code paths (MainForm, MCP, Console) now call
engine.Nest(items, progress, token) instead of manually orchestrating
sequential fill+pack. The default implementation in NestEngineBase
does sequential FillExact+PackArea. StripNestEngine overrides with
its strip strategy. This makes the engine dropdown actually work.
Also consolidates ComputeRemainderWithin into NestEngineBase,
removing duplicates from MainForm and StripNestEngine.
