M16-GAP-00202 Status

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

scope:

• The minimal fixture has two objects using WebGapAnimReplaceOldAction and one object using WebGapAnimReplaceNewAction. Desktop calls ANIM_OT_replace_action with the explicit action session UIDs.
• All three object users switch to the new action; the old action remains unlinked with its original channels. WASM/Main exposes both the replaced users and preserved unlinked action without reader/protocol changes.

evidence:

• Desktop evidence records the old/new action users, poll=true, FINISHED, ACTIONS_REPLACED, and exact save/reopen. Repeated checker runs preserve the initial evidence and fixture hash.
• WASM/Main compares three new-action targets and the unlinked old action, preserves them across save/reopen, and rejects malformed Blend input without Main mutation.
• Fixture generation, desktop checker, npm comparator, direct comparator, and task-context checks passed. Chromium-only policy was preserved; no Firefox/WebKit run was made.
