 ## Recent Reductions
 
+- 2026-06-13: `LATER-003` was narrowed again. `Canvas::stroke_draw()` now
+  routes its main live-pass bind, execute, and unbind sequence through
+  `execute_legacy_canvas_stroke_main_pass(...)`; the retained adapter still
+  owns the concrete sampler and texture callbacks.
 - 2026-06-13: RND-005 was completed. `desktop-gpu` now has a second

   is now done after the final pad-destination helper extraction and tracker
