A clamp is an avoidance area, so a clamp that only partly reaches a
sheet (for example centered at 60.5" on a 60" sheet, or near the
origin) now keeps its whole 1.5" x 0.625" footprint instead of being
clipped to the sheet; clamps wholly beyond the sheet are still left
off. Job validation accepts a zone that hangs past the sheet edges and
still rejects one that does not reach the sheet at all. Both packing
lanes already block keep-outs extending past the bin; a hanging-clamp
solve through Rectangles, Irregular and Default keeps every part clear
of the whole inflated footprint.
User decision 2026-10-12, settling the plan's pending D2 question.
NestPlateStock takes an optional clamp-zone list, translated into the
placement frame exactly like WorkArea (quadrants 1-4) and detached from
caller boxes; empty input keeps stock bit-identical to before. Plate
mappings (DrawingJobMapper.FromPlate/CreatePlate, NestStockBuilder) map
zones across; materialized plates carry them for checking.
NestJobValidator rejects zones outside the sheet or duplicate ids.
RepeatedPlateGrouping and NestLayoutCheck treat clamp sets as stock
identity (C8), and the layout checker flags part material inside a zone
inflated by bottom-edge spacing with the shared spacing slack (C1/C5) -
no tolerance loosened.
Every plugin engine rebuilt part material from a snapshot by hand and
filtered only rapids, so all three kept counting scribe/etch marks as
material after 1b5e1b1 fixed it in the host. JobPartGeometry is the
validator's own reader made public: SpecialLayers.IsMaterial, validated
closed contours, material area, and TryRead returning null for unreadable
parts. The job validators now use it, so engines and validation agree.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
Task 5 of the whole-job engine API: add a geometry safety gate that
validates every candidate trial before the runner commits accounting.
- NestJobPlacementValidator: closed-contour validity, rotation-policy
compliance, work-area containment per quadrant, hole-aware material
overlap, and required part spacing. Overlap is interior-only, so
zero-clearance edge/corner contact remains a valid placement.
- NestJobValidator: route candidate validation through the geometry
gate; reject unusable/unclosed/degenerate contours up front.
- NestJobRunner: wrap candidate evaluation in a progress bridge that
tags legacy engine detail with the current candidate context.
- LegacyPlateNesterAdapter: forward IProgress to the legacy engine so
its progress surfaces under the active candidate.
- Tests: geometry (quadrants, rotations, touching, containment, holes,
empty stock, real Default/Strip smoke), validation, and cancellation
suites; repaired test fakes that emitted out-of-bounds or overlapping
placements the gate now correctly rejects.
Engine.Tests: 70 passed, 0 failed, 0 skipped in Debug and Release.
Windows-only OpenNest.Tests not run on Linux.
