Extract direction helpers to Helper class (EdgeDistance, DirectionalGap,
DirectionToOffset, IsHorizontalDirection) and use them to skip parts not
ahead in the push direction or further than the current best distance.
Defer line computation until parts survive bounding box checks.

The BestFitFilter's aspect ratio cap of 5.0 was rejecting valid pair
candidates needed for narrow plates (e.g. 60x6.5, aspect 9.2) and
remainder strips on normal plates. Three fixes:
- BestFitFinder: derive MaxAspectRatio from the plate's own aspect
ratio so narrow plates don't reject all elongated pairs
- SelectPairCandidates: search the full unfiltered candidate list
(not just Keep=true) in strip mode, so pairs rejected by aspect
ratio for the main plate can still be used for narrow remainder
strips
- BestFitCache.Populate: skip caching empty result lists so stale
pre-computed data from nest files doesn't prevent recomputation
Also fixes console --size parsing to use LxW format matching
Size.Parse convention, and includes prior engine refactoring
(sequential fill loops, parallel FillPattern, pre-sorted edge
arrays in RotationSlideStrategy).

Move NFP-based AutoNest logic (polygon extraction, rotation computation,
simulated annealing) into dedicated AutoNester class. Consolidate duplicate
FillWithPairs overloads, extract BuildCandidateAngles and BuildProgressSummary,
reorganize NestEngine into logical sections. Update callers in Console,
MCP tools, and MainForm to use AutoNester.Nest.

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

Move brute-force data collection, TrainingDatabase, and GPU init from
OpenNest.Console into a dedicated OpenNest.Training project. Replaces

Calculate unused plate area by subtracting total part area from the

- 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

Run pairs phase first to establish a baseline before linear and

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.
