FAQ / Troubleshooting

Known Limitations

• Several TODO markers in worldsar indicate pending support improvements (metadata reorganization, extended modality support).
• Some APIs expose behavior primarily through implementation without full docstring detail.
• SNAP-based flows depend on external installation/runtime state.

Frequent Issues

GPT not found

Set --gpt-path or ensure gpt is on PATH and SNAP is installed.

Grid file missing

Set GRID_PATH or provide ./grid/grid_10km.geojson before running compose targets.

Upload authentication failure

Set HF_TOKEN or run Hugging Face CLI login before sarpyx upload.
