 Progress Notes:
 
+- 2026-06-13: `Canvas::stroke_draw` main, pad, and dual live-pass
+  texture-input binding/unbinding intent now routes through retained stroke
+  execution helpers; sampler binding, concrete GL object mapping, framebuffer
+  ownership, and final draw execution remain local to `Canvas`. Next slice
+  should target the remaining sampler binding/teardown or the direct
+  semantic-input-to-GL mapping callbacks without reopening the landed dirty,
+  face-framebuffer, or pad helpers.
 - 2026-06-13: `NodeStrokePreview::draw_stroke_immediate()` live-pass sampler
   binding, dual/main pass texture binding, checkerboard/background capture
   wrapping, and final preview copy-back now route through named local helpers;
