+### STR-044 - Extract Preview Sample Pass Request Construction
+
+Status: Ready
+Score: no score movement
+Debt: `DEBT-0036`
+Scope: `src/node_stroke_preview.cpp`, `tests/paint_renderer/compositor_tests.cpp`
+
+Goal:
+
+Move the remaining `execute_stroke_preview_sample_pass()` request construction
+into a retained helper so the executor wrapper keeps only request dispatch and
+dirty-bounds return handling.
+
+Done Checks:
+
+- `execute_stroke_preview_sample_pass()` no longer owns the sample-request
+  construction inline.
+- Regression coverage proves the helper preserves destination binding, copy,
+  and brush draw ordering.
+- `docs/modernization/debt.md` records the reduced preview sample-pass surface.
+
+Validation:
+
+```powershell
+ctest --preset desktop-fast --build-config Debug -R "pp_paint_renderer_compositor|pp_paint_renderer_stroke_execution" --output-onfailure
+cmake --build --preset windows-msvc-default --config Debug --target PanoPainter
+```
