 Progress Notes:
 
+- 2026-06-13: `Canvas::stroke_draw` current and dual stroke dirty-box mutation
+  now routes through `legacy_canvas_stroke_execution_services.h`; framebuffer
+  binding, shader uniform timing, sampler/texture binding, and draw execution
+  remain local to Canvas. Next slice should wrap the retained per-face
+  framebuffer/sample callback ordering without rewriting the new pad-pass or
+  commit executors.
 - 2026-06-13: `Canvas::stroke_commit` now routes retained commit input
   texture/sampler binding, erase/composite draw dispatch, committed-copy, and
   dilate draw through `legacy_canvas_stroke_commit_services.h`; history
