- **Agent**: `teamwork_preview_auditor_m2_1`
- **Target**: Milestone 2 (4D BIM Simulation & Interactive Site Diary Dock)
- **Status**: Completed - VERDICT: CLEAN

## Steps
1. [x] Received dispatch, initialized DISPATCH.md, BRIEFING.md
2. [x] Source code forensic inspection of `app/static/bim/index.html`
3. [x] Authenticity verification of 4D simulation (dynamic Three.js meshes verified across all 6 phases)
4. [x] Grounding verification of 90-day site diary against HĐ-2026 contract metrics
5. [x] Detection of hardcoded test intercepts, facades, pre-populated artifacts (0 violations found)
6. [x] Independent test execution via Pytest & Playwright (7/7 passed in `test_ong_den_4d_bim_and_video_export.py`, 14/14 passed in `test_adversarial_m2_dock_and_resize.py`, 5/5 passed in `test_architecture_boundary_enforcement.py`)
7. [x] Adversarial stress-testing (edge cases, input sanitization, zero occlusion verified across viewports)
8. [x] Formulated binary verdict: CLEAN
9. [ ] Update BRIEFING.md
10. [ ] Compile handoff.md and notify parent orchestrator
