11 tasks across 3 chunks: extract AccumulatingProgress, ShrinkFiller,
AngleCandidateBuilder, PairFiller, RemnantFiller, then rewire both
engines and NestEngineBase.

Add plateNumber parameter to PairFiller.Fill signature.
Document strip direction to ShrinkAxis mapping.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Extract shared algorithms from DefaultNestEngine and StripNestEngine
into focused helper classes: PairFiller, AngleCandidateBuilder,
ShrinkFiller, RemnantFiller, AccumulatingProgress.

Address review feedback: add holes parameter for parts with cutouts,
cache label point in program-local coords to survive zoom/pan, add
fallback for degenerate geometry, use ShapeProfile for outer contour
identification.

Active remnant shown as dashed orange rectangle on PlateView during
iterative fill workflow.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Extracts remnant detection from the nesting engine into a standalone
RemnantFinder class using edge projection algorithm, enabling an
iterative nest-area -> get-remnants workflow.

16 tasks covering test infrastructure, core model changes, part sequencing
(6 strategies + factory), rapid planning (2 strategies), and the PlateProcessor
orchestrator. TDD approach with xUnit tests for each component.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Fix coordinate transforms (translate-only, no rotation), make orchestrator
non-destructive (ProcessedPart holds result instead of mutating Part.Program),
use readonly structs consistently, add factory mapping and known limitations.

StripNester becomes StripNestEngine extending NestEngineBase.
Uses DefaultNestEngine internally via composition.
Registered in NestEngineRegistry.

Pluggable engine architecture with NestEngineBase, DefaultNestEngine,
registry with plugin loading, and global engine switching.

Design for training an XGBoost model to predict which rotation
angles are worth trying during FillLinear, reducing the 36-angle
sweep to 4-8 predicted angles in narrow-work-area cases.

Address spec review issues: add third call site (Fill groupParts),
reuse ComputeCandidateRotations, fix step ordering for ToNestParts
before scoring, cap N to 500 and item.Quantity, clarify BoundingBox
is a property.

Spec for adding NFP-based placement as a competing strategy
in NestEngine.FindBestFill() for non-rectangular parts.

Clarify engine return type ownership, cancellation propagation into
parallel loops, quantity decrement sequencing, conditional phase
behavior, plate navigation lockout, and MDI child close handling.

- Drop Circle.ToArcFrom (zero-sweep problem), keep Circle in shape
and handle in ConvertShapeToMoves with full-circle ArcMove
- Use point-distance tolerance for Arc.SplitAt instead of angle
comparison to avoid wrap-around issues at 0/2pi
- Simplify SplitAt return types to non-nullable tuple
- Add ArgumentException guard in ReindexAt
- Add throw for unexpected entity types in ConvertShapeToMoves
- Document absolute coordinate convention and shared references
- Clarify variable names for both replacement sites
The strategy output (lead-ins, start points, contour ordering) must be
saved in the nest file, so Apply() runs when parts are placed — not
during post-processing.

- Rename Angle properties to ApproachAngle (avoid shadowing Math.Angle)
- Arc rotation from contour winding, not hardcoded CW
- Add winding parameter to LeadIn/LeadOut Generate methods
- Add exit point derivation from Plate quadrant
- Add contour re-indexing section (split/reorder at closest point)
- Add ContourType.cs and AssignmentParameters.cs to file structure
- Clarify normal direction convention
- Note SequenceMethod value 6 intentionally skipped (PEP numbering)

Lead-in, lead-out, and tab class hierarchy for CNC cutting
approach/exit geometry, using ShapeProfile + ClosestPointTo
for contour sequencing.
