Civic Lens Remediation Lab helps municipal accessibility reviewers explore proposed temporary routes around street hazards. It extends a static 2D reporting website into an interactive 3D workbench where reviewers can inspect a wheelchair bypass around standing water, switch camera views, run a synthetic traversal check, and export evidence. The project integrates Gemini 4 Argon through the Interactions API to generate Three.js and Cannon-es scene code from a reference photo and scenario instructions. Its review workflow uses Playwright recordings, runtime telemetry, and source code to request structured critiques, proposed fixes, and subsequent retesting. An Antigravity Managed Agents integration also supports hosted code review and repair. The included scene and local traversal checks work independently of model access; live Argon and Antigravity execution remain unverified. Geometry and guided motion are illustrative, supporting human review rather than certifying real-world safety or accessibility compliance.
