# PAct Phase2 Mask Dropout / Edge-Prior Hard-5 Evaluation

- Samples: `0, 4, 26, 73, 97`
- Sampler policy: PAct official defaults; no `--ss_steps`, `--slat_steps`, `--ss_cfg_strength`, or `--slat_cfg_strength` passed.
- Dataset validation: `True`
- VLM: disabled.
- Output GLB texture export: disabled for this metric run to keep the hard-case evaluation lightweight.
