+### STR-036 - Extract Preview Main Live Pass Orchestration
+
+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 `NodeStrokePreview::draw_stroke_immediate()` main live-pass
+orchestration into a retained helper so the callsite keeps only branch
+selection and direct live-pass dispatch.
+
+Done Checks:
+
+- `NodeStrokePreview::draw_stroke_immediate()` no longer owns the main live-pass
+  orchestration inline.
+- Regression coverage proves the helper preserves live-pass branch order and
+  preview copy behavior.
+- `docs/modernization/debt.md` records the reduced preview live-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
+```
