M16-GAP-00174 Status

status: in_progress task: anim.driver_button_add operator LOCAL_EXACT slice updated: 2026-08-21 America/New_York

scope:

The minimal fixture contains an un-driven drive_target property; the reader preserves the object and the absence of drivers for WASM/Main.

evidence:

Blender desktop reaches the mandated Properties context, where ANIM_OT_driver_button_add reports poll=false because no active RNA button exists in -b; no operator mutation occurs.
Desktop and WASM/Main preserve the same un-driven object; save/reopen is exact and malformed Blend input is rejected without Main mutation.
Fixture generation, desktop checker, npm comparator, direct comparator, and artifact hashing passed.
Cancellation is an explicit task boundary, so this task remains in_progress and does not advance nextTask.
