Replace recursive FillRecursive with flat FillGrid that tiles along primary
axis, then perpendicular. Extract FindPlacedEdge, BuildRemainingStrip,
BuildRotationSet, FindBestFill helpers. Use array-based DirectionalDistance
to eliminate allocations in FindCopyDistance and FindPatternCopyDistance.
Simplify FindSinglePartPatternCopyDistance to delegate to FindCopyDistance.

Vector implements IEquatable<Vector> with proper GetHashCode for HashSet usage.
Polygon.FindCrossing uses bounding-box pruning to skip non-overlapping edge pairs.
Helper.DirectionalDistance deduplicates vertices via HashSet, sorts edges for
early-exit pruning, and adds a new array-based overload that avoids allocations.
PartBoundary sorts directional edges and exposes GetEdges for zero-alloc access.

Refactor flat top-level statements into NestConsole class with Options
and focused methods. Add support for passing .dxf files directly as
input — auto-imports geometry via DxfImporter and creates a fresh nest
with a plate when --size is specified. Supports three modes: nest-only,
DXF-only (requires --size), and mixed nest+DXF.

Linear phase shows "Linear: 12/36 angles, 45° = 48 parts" with a
running count. Pairs phase shows "Pairs: 8/50 candidates, best = 252
parts" tracking the best result seen so far. Reports on every
completion so the UI always reflects current state.

Parallel loops were flooding the UI with per-angle/per-candidate reports
faster than WinForms could render them. Use Interlocked timestamp checks
to report at most every 150ms, keeping descriptions readable.

Don't overwrite the Detail label with phase-level reports — let the
per-angle and per-candidate descriptions from the parallel loops remain
visible. Only clear the label on completion.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
ReportProgress was not setting Description, so the Detail row always
showed the default em-dash. Now each phase report includes a meaningful
description, and UpdateProgress always updates the label (resetting to
em-dash when null).

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.

Move brute-force data collection, TrainingDatabase, and GPU init from
OpenNest.Console into a dedicated OpenNest.Training project. Replaces
raw Microsoft.Data.Sqlite with EF Core. Console is now a pure nesting
CLI with template support and cleaned-up usage output.

Adds PerimeterToAreaRatio (perimeter / area) as a spacing sensitivity
indicator for ML feature extraction.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add FeatureExtractor for computing geometric part features (convexity,
aspect ratio, circularity, bitmask) and BruteForceRunner for generating
training data by running the fill engine and recording results.

Show a live elapsed-time counter that updates every second during
nesting. Rename "Remnant" label to "Unused" for clarity.

Calculate unused plate area by subtracting total part area from the
work area instead of relying on FillScore.UsableRemnantArea, which
could over-report available space.

Replace shape-list iteration with ShapeProfile.Perimeter in both
Part.Intersects and PartBoundary, simplifying the logic and ensuring
only the outermost contour is used for collision detection.

Add G-code serialization via ToString() for debugging/ML workflows.
Fix Rotate(angle, origin) to propagate origin to sub-programs instead
of calling the single-argument overload.

- Add verbose per-file and per-sheet-size console output during collection
- Skip already-processed parts at the sheet-size level instead of all-or-nothing
- Precompute best-fits once per part and reuse across all sheet sizes
- Clear best-fit cache after each part to prevent memory growth
- Save best-fits in separate bestfits/ zip entries instead of embedding in nest.json
- Filter to Keep=true results only and scope to plate sizes in the nest
- Set nest name to match filename (includes sheet size and part count)
- Add TrainingDatabase with per-run skip logic and SQLite schema

Wire up GpuEvaluatorFactory in the Console app the same way the GUI app
does, so BestFitCache uses GPU-accelerated slide computation when a
CUDA/OpenCL device is detected.

Run pairs phase first to establish a baseline before linear and
rect-best-fit phases. Replace IsBetterFill with direct FillScore
comparison. Simplify FillPattern to sequential iteration, reusing a
single FillLinear engine instance.

Compute min/max bounds in a single pass alongside part area
accumulation, avoiding the separate GetBoundingBox() call and
redundant iteration.

Store hull edge angles in BestFitResult at evaluation time so they
don't need to be recomputed during the fill phase. Extract
GetHullEdgeAngles(Polygon) overload from FindHullEdgeAngles.

Offset-only copies don't modify program codes, so sharing the instance

PageDown keyboard navigation.

Thread ISlideComputer through BestFitCache → BestFitFinder →
RotationSlideStrategy. RotationSlideStrategy now collects all offsets
across 4 push directions and dispatches them in a single batch (GPU or
CPU fallback). Also improves rotation angle extraction: uses raw geometry
(line endpoints + arc cardinal extremes) instead of tessellation to avoid
flooding the hull with near-duplicate edge angles, and adds a 5-degree
deduplication threshold.

ISlideComputer abstracts batched directional-distance computation so GPU
implementations can process all slide offsets in a single kernel launch.
GpuSlideComputer uses ILGPU with prepared edge data (precomputed inverse
deltas and min/max bounds) and caches stationary/moving buffers across
calls. GpuEvaluatorFactory exposes a singleton factory method.

Add primitive-parameter RayEdgeDistance overload with AggressiveInlining,
merge Left/Right and Up/Down cases. Add DirectionalDistance overload that
accepts (dx, dy) translation without creating Line objects, and FlattenLines
for packing segments into flat arrays for GPU transfer.

Break deeply nested loop structure into focused helper methods,

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

Brings in the full NFP implementation: ConvexDecomposition, NoFitPolygon,
InnerFitPolygon, NfpCache, BottomLeftFill, SimulatedAnnealing optimizer,
and INestOptimizer interface. Resolves conflicts by keeping master's
progress reporting infrastructure alongside the new AutoNest methods,
and adapting RunAutoNest_Click to use NFP AutoNest with async/cancellation.

Cache offset polygon geometry on LayoutPart so DrawOffset no longer
recomputes the expensive offset pipeline every paint cycle. The costly
OffsetEntity/ToPolygonWithTolerance/RemoveSelfIntersections chain now
runs only when rotation, spacing, or tolerance actually changes.
Also update temporary parts in UpdateMatrix() so preview parts during
nesting scale correctly with zoom.

Avoids visual confusion with reserved UI colors (orange preview parts,
green/blue selection windows) by using a fixed 12-color palette that
