The forward bounding-box gap check (gap < 0) incorrectly skipped obstacles
for irregular shapes like SULLYS-003 whose narrow handle extends past an
adjacent part's BB edge while the wide body still needs contact detection.
Replaced with a reverse-direction gap check that only skips obstacles the
moving part has entirely cleared. Also fixed edge distance check to prevent
overshooting the work area boundary when already at the limit.

Moving BasePart locations via Compactor.Push bypassed LayoutPart.Offset
which sets IsDirty. Without it, graphics paths were stale until a zoom
triggered a full rebuild.

PushSelected now calls Compactor.Push instead of duplicating the push
logic. Compactor.Push moves parts as a group (single min distance) to
preserve grid layouts. Compact tries both left-first and down-first
orderings, iterating up to 20 times until movement drops below
threshold, and keeps whichever ordering traveled further.
Also includes a cancellation check in FillWithProgress to avoid
accepting parts after the user stops a nest.

ComputeRemainderStrip used the bounding box of ALL plate parts against
the full plate, missing large interior gaps between drawing groups.
Now computes remainder within the current work area based on only the
parts that were just placed. This lets subsequent drawings fill the
gap between previous drawing groups instead of being forced into a
tiny strip at the plate edge.

Strip mode was adding thousands of candidates (7600+) when the work area
was narrow. Now caps at 100 total, sorted by utilization descending so
the best candidates are tried first.

The binary search was passing null for progress, so the NestProgressForm
showed all dashes during the entire search (potentially minutes). Now
each iteration reports progress — the user sees phases, part counts, and
density updating as the search runs.

- Track productive angles across Fill calls; subsequent fills skip
angles that never produced results (knownGoodAngles)
- Binary search uses utilization-based range estimates (70%-25%)
instead of starting from the full work area dimension
- Quick bounding-box capacity check skips binary search entirely
when the plate can't fit more than the requested quantity
- Use full Fill (not rect-only) for binary search iterations so
the search benefits from pairs/linear strategies

Previously each moving part only checked against the original stationary
set. Parts pushed earlier in the loop were invisible to later parts,
causing overlaps (utilization > 100%). Now each pushed part is added to
the obstacle set so subsequent parts collide correctly.

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,

MCP tools, and MainForm to use AutoNester.Nest.

Replace recursive FillRecursive with flat FillGrid that tiles along primary

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).

- 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
