# PAct supported-94 Stage2 repair

Date: 2026-05-17

This run repairs the previous failed fine-tune by keeping the official PAct architecture, restricting fine-tuning to PAct-supported GAPartNet categories, fixing inference mask labels to match the training loader's foreground +1 convention, and fine-tuning only Stage2 from official weights.

QA:
- samples: 3
- passed: 3
- pass rate: 1.000
- threshold: 0.750

Visual note: geometry is no longer collapsed into tiny fragments. All three checked samples export complete multi-part meshes with unit-scale AABBs and visible articulation animations. Refrigerator and storage furniture motion remains conservative, so this is a repaired baseline rather than a final solution.
