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. Project Memory: opennest 274836d5-fb76-4619-b3cc-0c811e767dd6
