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
avoids expensive cloning during large pattern tiling.

Replace single scrollable grid with fixed 5x2 pages (10 items per page).
Add prev/next buttons and page label. Support Left/Right and PageUp/
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,
reducing max nesting from 5 levels to 2. Uses GetRange/AddRange
for cleaner loop building.

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.

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
skips those hue zones. Removes unused HSLColor and RandomColorGenerator.

Moves async fill+progress orchestration into PlateView so ActionClone's
Ctrl+F fill shows the NestProgressForm dialog.

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

Shape.OffsetEntity computed joins between consecutive offset segments
but never joined the last segment back to the first, leaving the
closing corner with a straight line instead of a proper miter/arc.
Track the first entity and apply the same join logic after the loop.
Also wrap nest template loading in try-catch so a corrupt template
file doesn't crash the app on startup — falls back to default nest.

Replace engine.Pack(items) with individual engine.Fill(item) calls so each
drawing is filled independently. Quantity decrements now count parts actually
placed per plate (grouped by drawing) instead of relying on the drawing's
internal remaining counter.

The exit point should be the corner farthest from the origin so the
perimeter (cut last) ends near the machine home. The mapping was
backwards — Q1 (origin bottom-left) was returning (0,0) instead of
(w,l).

- 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.

Exit point from plate quadrant, nearest-neighbor cutout
sequencing via ShapeProfile + ClosestPointTo, contour type
