**Verdict**: REVISE

### Visible Issues

1. **Missing tideglass translucency**: The shafts and arch inner facings read as opaque, matte teal plaster rather than translucent sea-glass with subsurface depth and refraction.
2. **Arch extrados lacks ruin weathering**: The upper stone vault is modeled as clean, planar blocks with sharp grooves and zero edge chips, surface erosion, or moss growth.
3. **Unintegrated barnacle and grime passes**: Barnacle clusters appear as pasted chalky geometry with minimal ambient occlusion, lacking the transitional algae, dirt buildup, and wet-look staining shown in the reference sheet.

### Evidence Limits
- Evaluated via studio turntable renders (`final.png`, `side.png`, `clay.png`) under flat neutral lighting.
- Shading behavior under directional game-engine lighting, transmission/roughness maps in motion, and polycount budgets cannot be confirmed from static renders alone.
