- FillContext gains a Policy property (init-only) carrying the IFillComparer
- DefaultNestEngine.Fill sets Policy = BuildPolicy() on every context
- RunPipeline now uses context.Policy.Comparer.IsBetter instead of IsBetterFill
- RunPipeline promoted to protected virtual so subclasses can override
- BuildAngles/RecordProductiveAngles overrides delegate to angleBuilder
- RunPipeline calls virtual BuildAngles/RecordProductiveAngles instead of angleBuilder directly
- TODO comment added in group-fill overload for Task 6 Comparer pass-through

Add virtual comparer, direction, and angle-building hooks to NestEngineBase
so subclasses can override scoring and direction policy. Rewire IsBetterFill
to delegate to the comparer instead of calling FillScore directly.

Implements two IFillComparer strategies that preserve axis-aligned remnants:
VerticalRemnantComparer minimizes X-extent, HorizontalRemnantComparer minimizes
Y-extent, both using a count > extent > density tiebreak chain. Includes 12
unit tests covering all tiebreak levels and null-guard cases.

Extracts the fill result scoring contract into IFillComparer with a DefaultFillComparer implementation that preserves the existing count-then-density lexicographic ranking via FillScore.

- Convergence loop now uses FillLinear internally to measure actual
waste with geometry-aware spacing instead of bounding-box arithmetic
- Each candidate pair is tried in both Row and Column orientations to
find the shortest perpendicular dimension (more complete stripes)
- CompleteStripesOnly flag drops partial stripes; remnant strip is
filled by a full engine run (injected via CreateRemnantEngine)
- ConvergeStripeAngleShrink tries N+1 narrower pairs as alternative
- FillResultCache avoids redundant engine runs on same-sized remnants
- CLAUDE.md: note to not commit specs/plans

The convergence loop now ensures the pair starts with its short side
parallel to the primary axis, maximizing the number of pairs that fit.
Also adds ConvergeStripeAngleShrink to try N+1 narrower pairs, and
evaluates both expand and shrink results to pick the better grid.

Wire IDistanceComputer into RotationSlideStrategy, replacing inline
CPU/GPU branching. BestFitFinder constructs the appropriate implementation.
Replace PushDirection enum with direction vectors in BuildOffsets.
Rename IBestFitStrategy.Type and PairCandidate.StrategyType to StrategyIndex
for clarity (JSON field name unchanged for backward compatibility).

Extract distance computation from RotationSlideStrategy into a pluggable
IDistanceComputer interface. CpuDistanceComputer adds leading-face vertex
culling (~50% fewer rays per direction) with early exit on overlap.
GpuDistanceComputer wraps ISlideComputer with Line-to-flat-array conversion.
SlideOffset struct uses direction vectors (DirX/DirY) instead of PushDirection.
SpatialQuery.RayEdgeDistance(dirX,dirY) made public for CPU path.

Three bugs fixed in NfpSlideStrategy pipeline:
1. NoFitPolygon.Reflect() incorrectly reversed vertex order. Point
reflection (negating both axes) is a 180° rotation that preserves
winding — the Reverse() call was converting CCW to CW, producing
self-intersecting bowtie NFPs.
2. PolygonHelper inflation used OffsetSide.Left which is inward for
CCW perimeters. Changed to OffsetSide.Right for outward inflation
so NFP boundary positions give properly-spaced part placements.
3. Removed incorrect correction vector — same-drawing pairs have
identical polygon-to-part offsets that cancel out in the NFP
displacement.
Also refactored NfpSlideStrategy to be immutable (removed mutable
cache fields, single constructor with required data, added Create
factory method). BestFitFinder remains on RotationSlideStrategy
as default.

NFP strategy has coordinate correction issues causing overlaps.
The slide-based approach is fast and accurate — keeping it as default.
NfpSlideStrategy and PolygonHelper remain in the codebase for future use.

Calling ConvexMinkowskiSum directly with manual reflection produced
wrong winding/reference-point handling, causing all pairs to overlap.
Route through Compute which handles reflection correctly. Hull inputs
keep it fast — few triangles means trivial Clipper union.

ConvexMinkowskiSum is O(n+m) with no boolean geometry ops.
The concave Minkowski path was doing triangulation + pairwise
sums + Clipper2 Union, which hung at 100% CPU for complex parts.

Replace RotationSlideStrategy with NfpSlideStrategy in BuildStrategies,
and add integration tests covering the end-to-end FindBestFits pipeline.

Creates PolygonHelper.cs in OpenNest.Engine.BestFit with ExtractPerimeterPolygon
(returning PolygonExtractionResult with polygon + correction vector) and RotatePolygon.
AutoNester.ExtractPerimeterPolygon and RotatePolygon become thin delegates.
Adds MakeSquareDrawing/MakeLShapeDrawing to TestHelpers and 6 PolygonHelperTests.

Size(width, length) maps Width to vertical and Length to horizontal in
PlateView, but BoundingWidth (the longer dimension) was being passed as
Width (vertical) instead of Length (horizontal), causing the bounding
box to appear portrait instead of landscape.

In strip mode, build candidate list entirely from pairs whose
ShortestSide fits the narrow work area dimension, sorted by
estimated tile count. Previously, the top-50 utilization cut
ran first, excluding good strip candidates like #183.

Remove NeedsSweep that triggered a 5-degree sweep (36 angles) when
the work area was narrower than the part. Position matters more than
angle for narrow areas, and the base angles (bestRotation + 90deg)
cover the useful cases. ForceFullSweep still works for training.

Normalize pair bounding box to landscape (width >= height) in
PairEvaluator for consistent display and filtering. Fix

Add Compactor.Settle and AutoNester.Optimize post-passes to
NestEngineBase.Nest, StripNestEngine, and PlateView.FillWithProgress

Add Optimize method that re-places parts using NFP-based BLF, keeping
the result only if it improves density without losing parts. Fix
perimeter inflation to use correct offset side. Add NfpNestEngine
that wraps AutoNester for the registry. Register NFP engine.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add Settle method that repeatedly pushes parts left then down until
total movement falls below a threshold. Replaces manual single-pass
push calls for more consistent gap closure.

Refactor BLF to compute NFP paths as Clipper PathsD with offsets
instead of translating full polygons. Add spatial pruning to skip
NFPs that don't intersect the IFP bounds. Clamp placement points
to IFP bounds to correct Clipper2 floating-point drift. Add
progress reporting to simulated annealing. Add debug logging.

Move PlacedPart to its own file. Replace tuple-based sequences with
SequenceEntry struct for clarity. Add IProgress parameter to
INestOptimizer. Add IFP caching to NfpCache to avoid recomputing
inner fit polygons for the same drawing/rotation/workArea.

Add immutable Translate methods to Box. Make NoFitPolygon
ToClipperPath/FromClipperPath public with optional offset parameter.

directly, letting Clipper2 handle implicit union. Add UpdateBounds
calls after polygon construction.
