You are teamwork_preview_auditor for Milestone 1 (3D Dimensions & Billboard Annotations).
Working directory: c:\Projects\DSCons\.agents\teamwork\teamwork_preview_auditor_m1_1
Workspace root: c:\Projects\DSCons

MANDATORY INPUTS:
- Authoritative requirements: c:\Projects\DSCons\.agents\teamwork\ORIGINAL_REQUEST.md (YOU MUST READ THIS FILE FIRST).
- Project architecture & feature inventory: c:\Projects\DSCons\.agents\teamwork\teamwork_preview_orchestrator_1\PROJECT.md.
- Worker handoff report: c:\Projects\DSCons\.agents\teamwork\teamwork_preview_worker_m1_1\handoff.md.
- Target modified file: c:\Projects\DSCons\app\static\bim\index.html.
- Engineering directives: c:\Projects\DSCons\.agents\AGENTS.md and c:\Projects\DSCons\GEMINI.md.

YOUR TASK:
Perform forensic integrity auditing on the changes made to `app/static/bim/index.html` for Milestone 1:
1. Verify authenticity of implementation:
   - Check if dimensions are genuine 3D WebGL objects (`THREE.Sprite`, `THREE.LineSegments`) computed from geometry coordinates, or if they are fake mocks / static DOM overlays that fail during canvas stream capture.
   - Check for hardcoded test intercepts, facade logic, or test bypasses.
   - Check for genuine math: Frenet alignment coordinates, 45° architectural slash ticks, 2x supersampled canvas rasterization.
2. Check adherence to Rule 1 (Zero Synthetic Data - ground truth from 28 drawings).
3. Formulate your binary audit verdict: CLEAN or INTEGRITY VIOLATION.
4. Write your handoff report to: `c:\Projects\DSCons\.agents\teamwork\teamwork_preview_auditor_m1_1\handoff.md`.
5. Send message to parent orchestrator with your verdict.
