## Status
- [x] Initialized DISPATCH.md and BRIEFING.md
- [x] Read MANDATORY INPUTS: ORIGINAL_REQUEST.md, PROJECT.md, AGENTS.md, GEMINI.md
- [x] Inspect target code in `app/static/bim/index.html` and existing test runner `tools/verification/test_ong_den_4d_bim_and_video_export.py`
- [x] Formulate concrete stress test plan
- [x] Execute existing test suite: Checks 1 to 4 PASSED, Architecture boundaries PASSED (5/5)
- [x] Execute Playwright / headless Chrome stress test harness (`tools/verification/test_adversarial_m1_dimensions_stress.py`):
  - [x] 360-degree camera orbit at extreme angles (billboard legibility, facing camera, not flipping backward): PASSED (21 sprites, 100% camera-facing)
  - [x] Rapid dimension toggle 50 times (race conditions, dangling textures, memory leaks): PASSED (0 leaks, 21 textures constant, 49 geometries constant)
  - [x] Viewport resizing: Desktop FHD (1920x1080) & 4K (3840x2160) PASSED; Mobile (375x667) WebGL context intact (gl.isContextLost() == false), but container width collapses to 0px causing camera.aspect = 0 and projection matrix Inf/NaN.
  - [x] Console logs audit: PASSED (0 errors, 0 warnings)
- [x] Analyze results & document empirical findings with visual screenshots in `reports/stress_m1/`
- [ ] Write handoff.md
- [ ] Send verdict to parent orchestrator
