## Current State
- Completed adversarial geometric inspection of Three.js scene graph:
  - Verified exact child counts: 21 THREE.Sprite, 20 THREE.LineSegments, 0 unknown objects in `groupDimensions`.
  - Verified exact Euclidean distances $\|\mathbf{P}_B - \mathbf{P}_A\|$ matching dimension labels to 4 decimal places.
  - Verified WebGL canvas `captureStream(30)` capturing video stream with all 21 sprites rendered into framebuffer (54KB .webm blob recorded over 91 frames).
  - Verified FPS benchmark: 75.43 FPS average (min 74.07 FPS), well exceeding the >30 FPS threshold.
  - Verified Python test suites passing 100%:
    - `test_architecture_boundary_enforcement.py`: 5/5 PASSED
    - `test_ong_den_drawing_and_hsmt_grounding.py`: 5/5 PASSED
- Formulated verdict: APPROVE.
- Writing handoff.md and sending message to parent orchestrator.
