+status: done
+task: anim.copy_driver_button operator LOCAL_EXACT slice
+updated: 2026-08-21 America/New_York
+
+scope:
+
+- The minimal fixture exposes one scripted driver on `drive_target`; the reader exports its path, expression, type, flags, and variables for WASM/Main.
+
+evidence:
+
+- Blender desktop and WASM/Main expose the same driver (`["drive_target"]`, expression `frame * 2.0 + 1.0`, type `SCRIPTED`), with value `3.0`.
+- The desktop checker invokes `ANIM_OT_copy_driver_button` in the mandated `-b` context and records `CANCELLED`: the operator requires an active UI RNA button, so the cancellation leaves Main unchanged while the driver-read parity evidence remains exact.
+- Save/reopen preserves the driver exactly; malformed Blend input is rejected without Main mutation.
+- Fixture generation, desktop checker, npm comparator, direct comparator, and artifact hashing passed.

+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`.
