Introduces IterativeShrinkFiller.Fill, which composes RemnantFiller and
ShrinkFiller by wrapping the caller's fill function in a closure that tries
both ShrinkAxis.Height and ShrinkAxis.Width and picks the better FillScore.
Adds IterativeShrinkResult (Parts + Leftovers). Covers null/empty inputs and
single-item placement with three passing xUnit tests.

Includes fix for unlimited qty items (Quantity <= 0) that
RemnantFiller.FillItems silently skips. Workaround: convert
to estimated max capacity before passing in.
Also removes caliper angle sections from spec — RotationAnalysis
already feeds the caliper angle via FindBestRotation.

Kept using OpenNest.Api in Timing.cs and EditNestForm.cs alongside
remote's reorganized usings and namespace changes.

- NestRunner now assigns Material to plates from request.Material
- NestResponse.LoadAsync uses descriptive exceptions instead of null-forgiving operators
- Fix pre-existing FillExtents.Fill signature mismatch (add bestFits parameter)

Stateless orchestrator that takes a NestRequest and returns a NestResponse.
Imports DXFs, builds NestItems, runs the engine in a multi-plate loop until
all parts are placed, computes timing, and returns utilization metrics.

Adds NestResponse type to OpenNest.Api with SaveAsync/LoadAsync for .nestquote format — a ZIP containing request.json, response.json (metrics), and an embedded nest.nest.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds a Write(Stream) overload that writes the ZIP archive to any stream
with leaveOpen: true so the caller can read back a MemoryStream after
the ZipArchive is disposed. Refactors Write(string) to delegate to the
new overload.

Relocates CutParameters from OpenNest namespace to OpenNest.Api, adds
LeadInLength and PostProcessor properties, and provides a typed Default
factory. Updates Timing.cs, the WinForms project reference, and the three
consuming forms to resolve the type from the new namespace.

Design for OpenNest.Api project providing a stateless NestRequest/NestResponse
facade over the engine, IO, and timing layers. Includes CutParameters unification,
multi-plate loop, .nestquote persistence format, and .opnest → .nest rename.

Move PlateViews and labels to designer file so they show in VS.
Fix nest orientation by swapping Box(Width,Length) to Box(Length,Width)
matching plate convention (Length=X, Width=Y). Add ComboBox Format
handler to show Drawing.Name. Zoom to fit after moving parts.

Extract magic numbers into named constants (MaxTopCandidates,
EarlyExitMinTried, etc.), extract candidate evaluation into
EvaluateCandidate method, and expose BestFits property so
PairsFillStrategy can reuse without redundant BestFitCache call.

Replace SetTemporaryParts/ClearTemporaryParts/AcceptTemporaryParts in all
three progress callbacks (RunAutoNest, FillPlate, FillArea) with the new
two-bucket API: SetStationaryParts for IsOverallBest updates,
SetActiveParts for transient updates, AcceptPreviewParts(parts) and
ClearPreviewParts for completion. Also removes the now-redundant
highWaterMark guards from FillPlate_Click and FillArea_Click.

Replace single temporaryParts list with stationaryParts (overall best,
full opacity) and activeParts (current strategy, reduced opacity).
Update SetPlate, Refresh, UpdateMatrix, DrawParts, and FillWithProgress
accordingly. Replace SetTemporaryParts/ClearTemporaryParts/AcceptTemporaryParts
with SetStationaryParts/SetActiveParts/ClearPreviewParts/AcceptPreviewParts.

The pattern bounding box already computes max(upper) - min(lower), so the
manual loop was redundant. Extract the N×N pair distance loop into a static
FindMaxPairDistance helper. Drop pre-cached edge arrays since GetEdges()
returns stored references with zero allocation.

Also fix missing using for FillHelpers in FillLinear and FillExtents,
and update callers (CompactorTests, PatternTileForm) for the new
Vector parameter.

Move known-good pruning check before sweep/ML to avoid wasted work,
extract ContainsAngle, NeedsSweep, AddSweepAngles, ApplyMlPrediction,
and BuildPrunedList so Build reads as a clear pipeline.

FillExtents vertical copy distance was not clamped, allowing rows to be
placed overlapping each other when slide calculations returned large
values. Clamp to pairHeight + partSpacing minimum, matching FillLinear.
Also add FillStrategyRegistry.SetEnabled() to restrict which strategies
run — useful for isolating individual strategies during troubleshooting.

Promotes btnRemovePlate to a field and toggles Enabled based on
plate count in add/remove event handlers.

DensityBar: clamp rounded rect radius for small fill widths to avoid
GDI+ artifacts at very low density values.
PhaseStepperControl: use float arithmetic for circle spacing to
handle DPI-scaled widths evenly.

6-task plan covering PhaseStepperControl, DensityBar, form rewrite,
color-coded flash & fade, Accept/Stop buttons, and caller changes.

Phase stepper, grouped panels, density sparkline bar,
color-coded flash & fade, and Accept/Stop buttons.

Single-part group fills now delegate to Fill(NestItem) which runs
the full strategy pipeline, eliminating ~70 lines of duplicated
manual phase logic. Multi-part group fills retain the linear
pattern fill (unique to multi-part groups).
PairFiller now references FillHelpers directly instead of
bouncing through DefaultNestEngine helper methods.

Move AutoNester, BottomLeftFill, NfpCache, SimulatedAnnealing,
and INestOptimizer/NestResult to OpenNest.Engine.Nfp. These are
not yet integrated into the engine registry.

Move fill algorithms to OpenNest.Engine.Fill namespace:
FillLinear, FillExtents, PairFiller, ShrinkFiller, Compactor,
RemnantFiller, RemnantFinder, FillScore, Pattern, PatternTiler,
PartBoundary, RotationAnalysis, AngleCandidateBuilder, and
AccumulatingProgress.
Move strategy layer to OpenNest.Engine.Strategies namespace:
IFillStrategy, FillContext, FillStrategyRegistry, FillHelpers,
and all built-in strategy implementations.
Add using directives to all consuming files across Engine, UI,
MCP, and Tests projects.
