M16-GAP-00272 Status

status: done task: asset.catalog_undo operator LOCAL_EXACT slice updated: 2026-08-23 America/New_York

scope:

• The fixture links one object from external WebGapCatalogUndo.blend. Blender desktop observes the no-catalog-selection boundary as poll=false, records CANCELLED for ASSET_OT_catalog_undo, and confirms no Main mutation. Save/reopen preserves the Library record exactly.
• WASM/Main reads the same external Library with stable source path, EXTERNAL_REQUIRED status, and an empty dependency closure. The comparator confirms save/reopen stability and malformed-input rejection without Main mutation.

evidence:

• Fixture generation, desktop checker, npm comparator, direct comparator, and task context checks passed with exit code 0. Chromium-only policy was preserved and no Firefox/WebKit run was made. Blender's expected missing external-library warning is recorded by the comparator while the Library state remains exact.
