Task 6 of the whole-job engine API: adapt the public NestRequest/NestRunner/
NestResponse surface to delegate to the whole-job runner instead of a manual
quantity loop.
- NestRequest: optional explicit Plates stock list (null keeps the legacy
unlimited SheetSize fallback; empty list means no available stock),
optional per-part Id (derived as part-{index} when absent), and an explicit
PlacementStrategy that takes precedence over the legacy Strategy.
- NestRequestPlate: one physical-stock type (id, size, quantity, spacing,
quadrant).
- NestRunner: imports each DXF once, propagates priority/rotation constraints,
runs a single NestJobRunner solve, materializes ID/pose placements exactly
once, and reports aggregate utilization as total placed part area over total
physical sheet area.
- NestResponse: exposes status, stop reason, part fulfillment, stock usage,
and plate-to-stock mapping; .nestquote save/load gains a schema version and
reports completion as unknown for old archives lacking fulfillment metadata.
- Tests: extend the Api request/runner/persistence suites for legacy SheetSize,
explicit mixed finite stock, stock exhaustion, weighted utilization, old
archive loading, and new-archive round trips.
Verification: cross-compiles clean on net8.0-windows (Linux). The Api tests
require a Windows runner (net8.0-windows) and are NOT executed here; the
delegated engine logic is covered by the 70-test net8.0 Engine.Tests suite
(committed in Task 5). Windows runtime verification remains outstanding.
Task 5 of the whole-job engine API: add a geometry safety gate that
validates every candidate trial before the runner commits accounting.
- NestJobPlacementValidator: closed-contour validity, rotation-policy
compliance, work-area containment per quadrant, hole-aware material
overlap, and required part spacing. Overlap is interior-only, so
zero-clearance edge/corner contact remains a valid placement.
- NestJobValidator: route candidate validation through the geometry
gate; reject unusable/unclosed/degenerate contours up front.
- NestJobRunner: wrap candidate evaluation in a progress bridge that
tags legacy engine detail with the current candidate context.
- LegacyPlateNesterAdapter: forward IProgress to the legacy engine so
its progress surfaces under the active candidate.
- Tests: geometry (quadrants, rotations, touching, containment, holes,
empty stock, real Default/Strip smoke), validation, and cancellation
suites; repaired test fakes that emitted out-of-bounds or overlapping
placements the gate now correctly rejects.
Engine.Tests: 70 passed, 0 failed, 0 skipped in Debug and Release.
Windows-only OpenNest.Tests not run on Linux.
LegacyPlateNesterAdapter.Create now delegates to PlateNesterFactory
instead of carrying its own minimal Default-only switch, so built-in
strategy resolution has one source of truth. Behavior unchanged:
unknown keys still reject; all four built-ins now resolvable.
44 net8.0 tests pass in Debug and Release; 0 warnings.
Replace name-based quantity deduction with reference-based drawing
identity in the engine paths the whole-job runner reaches
(NestEngineBase fill/pack, StripNestEngine deduction, RemnantFiller
ledger, IterativeShrinkFiller leftovers). Add instance-scoped
PlateNesterFactory that resolves built-in strategies without touching
the global NestEngineRegistry. Add identity and engine-selection tests.
44 net8.0 tests pass in Debug and Release; no new warnings.
Change net8.0-windows to net8.0 in Core, IO, and Engine projects so
the libraries can be consumed in Docker containers running on Linux.

Add ChrFont, a reader for Gravograph .CHR engraving fonts, plus UI to
convert placed text into engraved geometry in the CAD converter.
The .CHR files are obfuscated with a single-byte XOR. Different
GravoStyle releases use different keys (0x2F in older versions, 0xCF in
the 7000 series, and others across the font library), so the key is
auto-detected from byte 1 of the file: the font name is ASCII stored as
UTF-16LE, so the high byte of its first character is 0x00 in plaintext
and the raw byte equals the key. This reads every font in a GravoStyle
install regardless of version, not just one hardcoded key.
UI: right-clicking a text item in EntityView raises TextConvertRequested;
CadConverterForm renders it via ChrFont with H/V alignment and adds the
result on an ENGRAVE layer.
Tests use Xunit.SkippableFact and a gitignored test-config.json so the
suite points at a local .CHR file without committing proprietary assets.

TextEntity import was only mapping HorizontalAlignment to CadText,
leaving VAlign at its default (Near/top). Middle-center text rendered
shifted to the bottom instead of vertically centered.

DXF files can contain degenerate arcs where start angle equals end angle
(zero sweep), often left as construction artifacts by CAD software.
These create spurious shapes in ShapeBuilder — e.g. SULLYS-033.dxf
showed 5 loops instead of 4 (3 cutouts + perimeter).

Parts that already overlap the moving group are now excluded from the
obstacle list so they don't block the push direction.

Duplicate circle entities at the same location inflated pierce counts
and cut pricing (e.g. SULLYS-035 showed 9 pierces instead of 8).

Add optional Func<string, bool> layerFilter parameter to ConvertEntities
and two new GetGeometry overloads (path and stream) that accept a layer
filter. This lets callers control which layers to exclude instead of
being limited to the hardcoded IsNonCutLayer check. Existing overloads
without the filter continue to use the default IsNonCutLayer behavior.

Extract MText and TextEntity from the CadDocument during DXF import
and render them in the EntityView. Handles text alignment (left/center/
right via InsertPoint vs AlignmentPoint) and replaces AutoCAD control
codes (%%p → ±, %%d → °, %%c → ⌀). MText formatting codes are
stripped before display.

ACadSharp already includes DwgReader, so this wires it up across the
entire import pipeline — Dxf.Import, CadConverter drag-drop, nest
import dialog, console CLI, BOM analyzer, and training data collector.

Verify that filling an L-shaped part produces consistent counts
regardless of the orientation it was imported at, and that all
placed parts stay within the plate work area.

Ellipse-to-arc conversion creates tiny floating-point gaps (~0.00002")
between consecutive arc segments. ShapeBuilder chains these with
ChainTolerance (0.0001"), but ConvertGeometry checked gaps with Epsilon
(0.00001"). Gaps between these thresholds generated spurious rapid moves
that broke GraphicsPath figures, causing diagonal fill artifacts from
GDI+'s implicit figure closing.
Root cause fix: align ConvertGeometry's gap check with ShapeBuilder's
ChainTolerance so precision gaps are absorbed instead of generating rapids.
Defense-in-depth: GraphicsHelper no longer breaks figures at near-zero
rapids, protecting against any programs with residual tiny rapids.

Near-zero-sweep arcs with large radius (e.g. from ellipse converter) have
nearly-coincident start/end points. Downstream code (ConvertProgram, Program
BoundingBox) treats coincident start/end as a full 360° circle, inflating the
bounding box and rendering wrong geometry. Emit a LinearMove when sweep is
negligible — geometrically equivalent and avoids the ambiguity. Also fix the
ellipse converter to produce lines instead of degenerate arcs at the source.

Arcs with sweep angles smaller than Tolerance.Epsilon were treated as
full circles by IsBetweenRad's shortcut check, causing UpdateBounds to
expand the bounding box to Center ± Radius. This made zoom-to-fit zoom
out far beyond the actual part extents.
Skip cardinal angle expansion when sweep is near-zero so the bounding
box uses only the arc's start/end points.

Ellipses with extrusion direction Z=-1 had their parametric direction
reversed, causing the curve to appear mirrored. Negate start/end
parameters when Normal.Z < 0 to correct the minor-axis traversal.

Replaces PartBoundary polygon edges with PartGeometry.GetOffsetPerimeterEntities
(inflated Line/Arc entities) so arcs are handled exactly without the polygon
sampling error that previously required a bboxDim + PartSpacing clamp. Adds
bbox DirectionalGap / PerpendicularOverlap early-outs to skip pair checks
that can't produce a valid slide, and removes the now-unused PartBoundary
cache, GetPatternLines/GetOffsetPatternLines helpers, and ComputeCopyDistance
clamp.

NfpSlideStrategy wrote to nfp-slide-debug.log on the Desktop on every
call. The console's SetUpLog created test-harness-logs/ next to input
files but nothing in the codebase wrote to Trace, so those files were
always empty. Drop both along with the --no-log flag.

Shape library drawings now get descriptive names based on their
parameters (e.g. "Rectangle 12x6", "Circle 8 Dia") instead of generic
type names, preventing silent duplicates in the DrawingCollection
HashSet. Added a Shape Library button to the Drawings tab toolbar
and removed separators between toolbar buttons for a cleaner look.

Tabs were being applied to internal cutouts and circle holes, which is
incorrect — only the external perimeter should be tabbed. Restructured
the Tabs panel to use radio buttons ("Tab all parts" vs "Auto-tab by
smallest dimension") so the two modes are clearly mutually exclusive
instead of the confusing implicit override behavior.
