Evaluation Data: IM-MA mesh geometry defect breakdown across 101 exports

Hi IM-3D / Meta GenAI team,

I ran an open, reproducible geometry QA census (`3dqa-benchmark`) across 2,307 generative exports from 23 models.

**IM-MA Metrics (n=101):**
- Non-watertight: 84.2%
- Non-manifold edges: 53.5%
- Missing UVs: 100%
- Vertex-colour-only exports: 100%
- Exceeding 30k budget: 0.0%

Full reproducible CLI runner (`pip install 3dqa`) and aggregate reports are available at:
https://github.com/alza123123/3dqa-benchmark

Start with the linked 3dqa-benchmark CLI runner and its aggregate reports to reproduce the IM-MA measurements. The issue names no repository files, tests, or specific requested change; completion would require clarifying which geometry defect to address and how the 101 exports should be evaluated.
