+# VDE-056: ViewDesign UI P0-1 — ViewportWidget and SIMD layer progress
+
+- **ID**: VDE-056
+- **Date**: 2026-07-29
+- **Status**: fixed
+- **Severity**: Info
+- **Category**: INTEGRATION
+- **Source**: ViewDesign Task 10 & 12
+
+## Summary
+ViewDesign Task 10 (UI Availability Plan) and Task 12 (Hardware Utilization) have been started.
+Changes are in ViewDesign repo, no VDE changes needed at this time.
+
+## ViewDesign Changes (2026-07-29)
+
+### Task 11: Architecture Remediation P0 (COMPLETED)
+- 82 CMakeLists.txt: removed `src/vd_geom/src` PRIVATE include paths
+- shape_impl.h moved to public `include/vd/geom/` directory
+- python314.dll copy added to test directory (fixes 0xC0000135 DLL not found)
+- VDE submodule bumped: MSVC `__builtin_prefetch`/`__builtin_ia32_pause` compatibility
+
+### Task 10: UI P0-1 ViewportWidget (COMPLETED)
+- New `src/vd_shell/viewport_widget.h/.cpp`: QWidget-based 3D viewport
+  - Replaces QLabel placeholder with dark background + axis/grid
+  - Mouse events forwarded to `render::Viewport` (orbit/pan/zoom)
+  - 60fps timer ready for bgfx rendering integration
+- MainWindow: Ribbon buttons now route through ICommandService
+- vd_shell links to vd_render for viewport integration
+
+### Task 12: SIMD P0-2 (COMPLETED)
+- New `src/vd_geom/include/vd/geom/simd.h`: cross-platform SIMD detection
+- New `src/vd_geom/include/vd/geom/simd_vec3.h`: batch Vector3D ops
+  - AVX2: Vec3Batch8 (8-way add/dot/cross/normalize)
+  - SSE2: Vec3Batch4 fallback
+  - Scalar fallback always available
+- vd_geom CMakeLists.txt: auto-detect `/arch:AVX2` support
+- CPU: Intel Core Ultra 9 290HX Plus (24-core, AVX2+FMA)
+
+## Build Status
+- ViewDesign: 100% build (190 files, 0 errors)
+- Tests: 117+ spot-check PASS
+- Shell: startup self-check PASS (exit 0)
+
+## VDE Issues Encountered
+- None new. VDE-055 MSVC fixes already applied (commit 55dc3a2).
+- VDE continues to build clean under MSVC with these fixes.
+
+## Known Issues
+- vd_tests.exe full suite runtime occasionally hangs with AVX2 - needs investigation
+- bgfx rendering not yet connected (VD_ENABLE_BGFX=OFF default)
+- Qt DLLs not auto-deployed to vd_shell output (manual copy needed for GUI)
