+### STR-038 - Extract Preview Pass Sequence Request Assembly
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0036`
+Scope: `src/node_stroke_preview.cpp`, `tests/paint_renderer/compositor_tests.cpp`
+
+Goal:
+
+Move the remaining `NodeStrokePreview::draw_stroke_immediate()` pass-sequence
+request assembly into a retained helper so the callsite keeps only the
+sequence wrapper and final state restoration.
+
+Closeout: `3672f9a5`
+
+Done Checks:
+
+- `NodeStrokePreview::draw_stroke_immediate()` no longer owns the pass-sequence
+  request object inline.
+- Regression coverage proves the helper preserves dual/main sequence ordering
+  and copy behavior.
+- `docs/modernization/debt.md` records the reduced preview pass-sequence
+  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
