M16-GAP-00199 Status

status: done task: anim.paste_driver_button operator LOCAL_EXACT slice updated: 2026-08-22 America/New_York

scope:

• The minimal fixture contains one mesh object with a driven source_target custom property and an undriven paste_target custom property. Desktop UI evidence copies the source driver and pastes it into the target through ANIM_OT_paste_driver_button.
• The saved fixture exposes both scripted drivers with the same expression in WASM/Main; no reader, protocol, or browser change was required.

evidence:

• Desktop evidence records the source/target driver state before and after the UI operation, poll=true, FINISHED, DRIVER_PASTED, and exact save/reopen. The checker also preserves this evidence on repeated runs.
• WASM/Main reads both drivers from the same fixture, preserves them across save/reopen, and rejects malformed Blend input without Main mutation.
• Fixture generation, foreground desktop checker, npm comparator, direct comparator, and task-context checks passed. Chromium-only policy was preserved; no Firefox/WebKit run was made.
