- Decision: `SAFETENSORS_MODELS` uses full repo ids, so On Device `unsloth/Qwen-Image-2512-FP8` resolves to `single_file`.
- Created `/mnt/disks/unslothai/ubuntu/workspace_81/scripts/studio_ondevice_load_verify.py`.
- Ran E2E: FP8 On Device click loaded `model_kind='single_file'`; unloaded OK.
- COMPLETED: fixes verified. PENDING: SDXL/#196/#185.
