- export_gltf.py: replace single-material fallback (only fired when len(appended)==1) with a universal sentinel that appends SCHAEFFLER_059999_FailedMaterial unconditionally and assigns it to every mesh object not matched by name-based lookup. Also adds in-memory magenta fallback if library append fails. Removes 2 temporary [DEBUG] print lines from investigation. - blender_render.py: add FailedMaterial assignment inside _apply_material_library() for unmatched parts (was log-only before). Includes copy-on-write guard (users > 1) matching existing pattern. Also added alias 'Stahl; Durotect CMT' (semicolon) → Durotect-Blue to cover STEP files using semicolon separator instead of comma. Verified: 23/25 objects matched correctly, 2 ISO8734 dowel pins (empty material) receive SCHAEFFLER_059999_FailedMaterial as sentinel. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
