Adds LayerType.Leadin to all LinearMove and ArcMove instances produced
by LineLeadIn, ArcLeadIn, LineArcLeadIn, CleanHoleLeadIn, and
LineLineLeadIn Generate() methods, plus tests covering all subclasses.

Adds Suppressed bool to the Motion base class so LinearMove, ArcMove,
and RapidMove can be flagged for skip during rendering and post-processing
when they fall within a tab gap. Clone() updated on all three subclasses
to preserve the flag. Covered by new MotionSuppressedTests.

- Add radius-based arc feedrate calculation (Variables/Percentages modes)
with configurable radius ranges (#123/#124/#125 or inline expressions)
- Fix arc distance in SpeedClassifier using actual arc length instead of
chord length (full circles previously computed as zero)
- Fix G89 P spacing: P now adjacent to filename per CL-707 manual syntax
- Add lead-out feedrate support (#129) and arc lead-in feedrate (#127)
- Fix pallet exchange: StartAndEnd emits M50 in preamble + last sheet only
- Add G121 Smart Rapids emission when UseSmartRapids is enabled
- Add G90 absolute mode to main program preamble alongside G20/G21

Add ArcFit.FitWithDualTangent to constrain replacement arcs to match
tangent directions at both endpoints, preventing kinks without
introducing gaps. Add DXF year selection to CAD converter export.

Remove pass-through wrappers (FitWithStartTangent, MaxRadialDeviation), extract
PerpendicularDistance and NormalizeAngle helpers to deduplicate mirror axis math,
convert GetExitDirection to switch expression, and simplify ComputeEndTangent.

Change Nest() to decide fill vs pack based on total area coverage
instead of qty != 1. Items covering < 10% of the plate are packed,
so large parts get prime position and small low-qty parts fill gaps.
Qty=2 items are placed as interlocking best-fit pairs in remnant
spaces after the main pack phase, rather than as separate rectangles.
- Add ShouldFill() capacity-based heuristic
- Split pack phase: regular items pack first, then pairs
- Add PlaceBestFitPairs() for Phase 3 remnant pair placement

For qty 1-2, skip the full 6-strategy pipeline: place a single part
or a best-fit pair directly. For larger low quantities, shrink the
work area in both dimensions (sqrt scaling with 2x margin) before
running strategies, with fallback to full area if insufficient.
- Add TryFillSmallQuantity fast path (qty=1 single, qty=2 best-fit pair)
- Add ShrinkWorkArea with proportional dual-axis reduction
- Extract RunFillPipeline helper from Fill()
- Make ShrinkFiller.EstimateStartBox internal with margin parameter
- Add MaxQuantity to FillContext for strategy-level access

Break the 113-line click handler into single-responsibility methods:

Refresh PlateView preview with settled parts after Compactor.Settle

- Skip ExtentsFillStrategy for rectangle/circle parts
- Skip PairsFillStrategy for circle parts
- PackBottomLeft now tries rotated orientation when items don't fit
- PackBottomLeft tries both area-descending and length-descending sort
orders, keeping whichever places more parts (tighter bbox on tie)
- Add user constraint override tests for AngleCandidateBuilder

Replace RotationAnalysis.FindBestRotation with PartClassifier.Classify in
RunPipeline, propagate ClassificationResult through BuildAngles signatures and
FillContext.PartType, and rewrite AngleCandidateBuilder to dispatch on part type

- Route best-result updates to progress form preview in
PlateView.FillWithProgress (Ctrl+F path) — was still using

- Only update results stats (parts, density, area) when
IsOverallBest so they match the preview display

Replace verbose value tuple with named PartPair record struct, extract
AnchorToWorkArea/PairBbox helpers to eliminate duplication, and delegate
RepeatColumns to FillLinear.Fill which already handles geometry-aware
column tiling with overlap fallback.

Polygon-polygon collision detection using convex decomposition (ear-clipping
triangulation) followed by Sutherland-Hodgman clipping on each triangle pair.
Handles overlapping, non-overlapping, edge-touching, containment, and concave
polygons. Includes hole subtraction support for future use.

Immutable result type that holds overlap flag, overlap regions (as polygons),
intersection points, and computed overlap area.

FillGrid had no overlap check after perpendicular tiling of the row
pattern (Step 2), unlike Step 1 which had one. When geometry-aware
FindPatternCopyDistance underestimated row spacing, overlapping parts
were returned unchecked.
Changes:
- Make FillLinear.HasOverlappingParts shape-aware (bbox pre-filter +
Part.Intersects) instead of bbox-only, preventing false positives on
interlocking pairs while catching real overlaps
- Add missing overlap safety check after Step 2 perpendicular tiling
with bbox fallback
- Add diagnostic Debug.WriteLine logging when overlap fallback triggers,
including engine label, step, direction, work area, spacing, pattern
details, and overlapping part locations/rotations for reproduction
- Add FillLinear.Label property set at all callsites for log traceability
- Refactor LinearFillStrategy and ExtentsFillStrategy to use shared
FillHelpers.BestOverAngles helper for angle-sweep logic

EllipseConverter computed arc radius from start point only, causing
~0.0009 unit gaps between consecutive arcs. Use circumcircle of

Extract shared BestFitAxis helper parameterized by orientation,

StripeFiller and FillExtents had identical 24-line overlap detection
methods; move to FillHelpers and delegate from both callers.

Convex corners were being miter-joined (lines extended to a point)
because IntersectsUnbounded always finds an intersection for non-parallel
lines. Now checks the cross product of original line directions to detect
convex corners and inserts an arc instead.

- Part.Intersects: filter intersection points at a vertex of either
shape (was both), so edge-touching parts are not flagged as overlapping
- NestEngineBase.HasOverlaps: use epsilon-based bounding box pre-filter
consistent with FillExtents and Plate.HasOverlappingParts
- PartGeometry.GetOffsetPartLines: remove extra chordTolerance added to
spacing offset — was causing 0.002" gap beyond the intended part spacing

UpdateEtchEntities was removing all entities on the ETCH layer, which

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.

Shape.OffsetOutward produces inward offsets for certain rotated polygons,
causing geometry-aware copy distances to be too small and placing
overlapping parts. Root cause is in the offset winding direction
detection — this commit adds safety nets while that is investigated.
- FillLinear.FillGrid: detect bbox overlaps after geometry-aware tiling,
fall back to bbox-based spacing when overlaps found
- FillExtents.RepeatColumns: detect overlaps after Compactor computes
copy distance, fall back to columnWidth + spacing
- PairFiller/StripeFiller remnant fills: use FillLinear directly instead
of spawning full engine pipeline (avoids strategies with the bug)
- Add PairOverlapDiagnosticTests reproducing the issue
- MCP config: use shadow-copy wrapper for dev hot-reload
