FillItem_WithClampZones_PinnedLayout (Fill, Strip, Vertical Remnant) has
failed in the Engine.Tests CI job on every push since it was added in
ccd361d: the pinned digest 9BF5FC7FC47364A9 is not reproducible at that
commit or any later one, locally or on GitHub runners. The engine
deterministically yields 9B3EFF9B72243576 (Fill, Strip) and
039C0D607166D805 (Vertical Remnant) at ccd361d, 36c8de8 and master, so the
later filler consolidation is still layout-neutral for these cases.
Before repinning, all four strategies' layouts were checked: 40 parts, all
inside the work area, bounding boxes clear of both clamps, and no
overlapping parts.

DefaultPlateFiller becomes PlateFiller(plate, policy, layout); PlateFillerBase
and StripPlateFiller are gone. PlateLayout.FillThenPack is the old
orchestrator path (Fill and both Remnants); PlateLayout.Strips is the old
StripPlateFiller.Nest, and Strip is Fill policy plus Strips layout.
Lifetimes are unchanged: a strip-layout filler runs every Fill, group Fill
and PackArea on a fresh inner filler and gives each strip fresh remnant
fillers, so learned angles and PlateNumber never leak into them. The
comparer, preferred direction, trim axis and angle recording now read the
policy directly. The base class's unsorted two-angle BuildAngles is dropped:
only DefaultPlateFiller's pipeline called BuildAngles, and Strip never ran it.
Layout-neutral: all 29 FillStackCharacterizationTests pins pass unchanged.

NestLayoutCheck rejected Fill layouts whose interlocked arcs sat exactly
at the part spacing: its SpacingOutline circumscribes arcs by up to 0.001
each, more than the 0.0005 slack, so facing arcs overlapped. The runner's
placement validator measured inscribed 0.001 polygons instead and so
accepted gaps up to ~0.002 under the slack.
Both now find candidates with SpacingOutline and confirm them on
NativeContours, the native contours flattened at a twentieth of the slack
(moved out of PartSpacingReview, which keeps using them). The runner calls
NestLayoutCheck.KeepsSpacing, the same outline, tie rule and
confirmation, so the two validators accept exactly the same pairs.
Clears stays unconfirmed and stricter for engine certification. No
tolerance changed.
FixedStrategyEngine_IrregularJob pins now assert LayoutAssert.Valid with
unchanged digests; the NativeU 70-part grid's 28 reports were the same
cause and its test now requires none.

BestFitFinder gathered each rotation strategy's candidates, and PairEvaluator
gathered evaluated results, in ConcurrentBags, so their order depended on which
worker finished first. The stable area sort then broke equal-area ties in that
arbitrary order, and fills, which try candidates in order and keep the first of
equal layouts, could nest the same parts differently between runs.
Both now fill index-addressed slots: candidates keep rotation-angle and
slide-offset order, results keep candidate order, and ties break the same way
every run. The candidates produced and their scores are unchanged.
The Strip whole-job pin in FillStackCharacterizationTests is re-pinned
(A66602F707290A36 -> FD03A4529D37E32C). That job ties between best-fit
pairs; the old pin recorded whichever tied pair the bag happened to return
first. The new layout places the same 26 parts, passes LayoutAssert.Valid
and gave the same digest in five separate test processes. The other 28
pins are unchanged.

Characterization digests for the interactive PlateFillService surface and
the fixed-strategy whole-job engines on L-shaped, notched, arc, bar and
chevron parts: single-item fills, whole-plate nests (including one where
learned angles change the layout, guarded by a full-sweep comparison),
fills beside clamp zones, and one job per Fill/Strip/remnant engine.
They let the planned filler/nester consolidation be shown layout-neutral.
