+### STR-055 - Extract Stroke Commit Sequence Wrapper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0036`
+Scope: `src/canvas.cpp`, `tests/paint_renderer/stroke_execution_tests.cpp`
+Closeout: `d5af0b98`
+
+Goal:
+
+Move the remaining `Canvas::stroke_commit()` sequence wrapper into a retained
+helper so the callsite keeps only request assembly and dispatch.
+
+Done Checks:
+
+- `Canvas::stroke_commit()` no longer owns the sequence wrapper inline.
+- Regression coverage proves the extracted helper preserves the commit request
+  build and execution order.
+- `docs/modernization/debt.md` records the reduced stroke-commit wrapper
