Every nesting-geometry consumer filtered only rapids, so scribe/etch moves counted as part material. An etch tick that ends a hair outside the outline (PEP bend ticks start on the notch edge) made the part "open geometry leaving the material region": the job validator threw and every built-in engine plus Gpt6Astra crashed on real PEP jobs (PT75, drawing 4980 A01 PT77). Marks are only on the surface, so they should never affect placement, collision, area, or validation. - SpecialLayers.IsMaterial excludes Rapid and Scribe; used by drawing area, canonical angle, part collision, PartGeometry, plate perimeter, best-fit/pair evaluation, rotation analysis, GPU evaluators, and both validators. Timing, display, splitting and posts still see marks. - ConvertGeometry also maps the saved SCRIBE layer name to Scribe, so programs rebuilt from stored entities keep their marks. - NestReader repairs older files (e.g. PepNestExport output) whose programs saved etch as cut moves while source entities kept SCRIBE.
