When the end tail was shorter than the minimum tail to keep, the planner
dropped the separator but still stopped the strip grid at it, so the last
strip ran to the sheet end and could exceed the maximum spacing (e.g. a
39-inch strip from 105 to 144 with 35-inch spacing). The grid now spans the
whole sheet whenever the separator is skipped, keeping every strip within
the spacing.

A direct CutOff.Regenerate(plate, settings) call with no perimeter
cache argument trusted Part.BoundingBox plus a sub-epsilon roundoff
allowance. A legitimately larger arc refit (ConvertProgram fitting
an imported arc's center to its chord) can protrude past that cached
box by more than the roundoff, so an uncached manual cutoff could
emit a segment crossing the part's true converted material.
Every production call site (Plate.RegenerateCutOffs,
AutomaticCutOffPlanner, the desktop cutoff tools) already builds and
passes a Plate.BuildPerimeterCache dictionary, so this only affects a
direct/uncached caller. Extract the per-part conversion out of
BuildPerimeterCache into Plate.BuildPartPerimeter and use it as a
lazy, on-the-fly fallback in CutOff.ComputeSegments whenever no cache
dictionary is supplied at all, so the uncached path gets the same
conservative envelope as the cached one instead of silently trusting
the bare bounding box. Cached behavior (including a cache's own
explicit null entries from a failed conversion) is unchanged.

Plate.ClampZones are stored relative to the sheet's lower-left corner,
but cut-off positions, motions and part poses use the signed quadrant
frame. The automatic cutoff planner, manual cut-off contacts, clamp
rapid warnings and whole-plate overlap capture compared the two
directly, so in quadrants 2-4 a cut or rapid through a real rail clamp
was neither avoided nor warned about.
Add ClampZoneFrame.ToPlacement, which maps live zones into the
placement frame exactly like the sheet and engine stock, and use it in
every Slice 5 consumer. It rejects missing or malformed zones (bounds
stay publicly mutable); pre-post verification reports those as an
incomplete clamp check instead of a clear result. Overlap freshness now
treats a size or quadrant change as moving the zones.
Tests use real ClampRail zones in all quadrants; the hand-signed
quadrant fixtures that hid the defect are converted to rails.

The automatic cutoff planner tested only the proposed X against active
clamp spans, then certified a tolerance-close existing line at its own
X. A manual line just inside a clamp edge could therefore be reported
as a verified tail separator. Test the proposed X and every equivalent
existing definition before regenerating.
Also keep a same-line limited manual cut blocking the whole plan when
it lies on a clamp, as it did before clamp checks were added.
