UTC 2026-05-24T19:36:50Z

UX assessment

  • pass: True
  • avg_score: 2.14
  • min_score: 1.5
ID Score Note
UX-01 2 render_wgpu_viewport_smoke ties ViewportRegion; pixels still paint IR (Godot/Blender = 3).
UX-02 2 Timeline region unchanged (DaVinci/Unreal = 3).
UX-03 2 Inspector via li-gui paint (Unity/Figma = 3).
UX-04 2 Command palette mock (Linear/VS Code = 3).
UX-05 2 Profile chip HTML (Notion = 3).
UX-06 2 Agent strip mock (Cursor/Copilot = 3).
UX-07 2 Empty viewport mock + smoke size guards.
UX-08 2 wgpu_smoke stub_pass + surface_ok=false (Primer = 3).
UX-09 2 Panel switch hooks from studio-ux-02.
UX-10 2 Token contrast; ux-harness pass.
UX-11 1.5 No skeleton loaders (Material 3 = 3).
UX-12 2 render/gpu API terminology consistent.
UX-13 3 FPS counter + bench viewport_fps JSON; native_pixels=false.
UX-14 3 HUD honest: bench simulate, not native wgpu surface.

Regressions: none vs studio-ux-02.

SOTA (agentic_ai): Cursor (task/status clarity), Linear (progress affordances), GitHub Copilot Workspace (error recovery patterns).
