WBV2-P2-004 status

  • task: WBV2-P2-004
  • parent: WBV2-P2-003
  • parity: VIEWPORT.MAIN_OFFSCREEN
  • implementationClass: LOCAL_BOUNDED
  • status: done
  • fixture: tests/files/web/generated/WBV2-P2-004-VIEWPORT.MAIN_OFFSCREEN.blend

Evidence

  • Desktop and WASM load the same cube/camera SceneIR and preserve node, mesh, camera and scene data across save/reopen.
  • Chromium production dist renders nonblank pixels through both main-thread WebGL and Offscreen worker paths.
  • Selection and camera state are identical across backends; main-thread WEBGL_lose_context recovery returns ready with nonblank readback, and Offscreen disposal/reopen is exact.
  • Malformed blend input is rejected without mutating Main.
