1. Verify 4D Player Controls (Feature F7): Play/Pause (`#btnPlayPause`), speeds (1x, 2x, 5x), timeline slider (`#timelineSlider`, 1 to 90), day badge, phase badge, and phase jumper buttons.
2. Verify 6-Phase Simulation Engine (Feature F8): Sheet 04 sequence: Site Prep (1-10) -> Larsen shoring (11-25) -> Excavation & Bamboo piles (26-45) -> Culvert walls 3 segments (46-70) -> Slabs & Manholes (71-82) -> Pull Larsen & backfill (83-90).
3. Verify test runs:
   - `.venv\Scripts\python.exe -m pytest tools/verification/test_ong_den_4d_bim_and_video_export.py -v -k "test_check_5"`
   - `.venv\Scripts\python.exe -m pytest tests/test_architecture_boundary_enforcement.py -v`
4. Formulate your explicit verdict: APPROVE or REQUEST_CHANGES.
5. Write your handoff report to: `c:\Projects\DSCons\.agents\teamwork\teamwork_preview_reviewer_m2_1\handoff.md`.
