 - Paper/model: [radar-generalist/RADAR](https://huggingface.co/radar-generalist/RADAR) (CC BY-NC-SA 4.0, non-commercial research use only)
 - Source: vendored inference code from the RADAR release (Zenodo `damo-radar.zip`, record `21271172`); weights load at runtime from the public HuggingFace repo, no token needed
-- Runtime: ZeroGPU (`large`), single `@spaces.GPU(duration=180)` call per volume; preprocessing (1x1x5mm resample, 96x256x384 pad/crop) is the upstream MONAI chain, reused verbatim
+- Intake: everything normalizes to one `.nii.gz` via SimpleITK (no new deps); header+raw pairs (`.mhd`/`.nhdr`) need converting first. Multi-file uploads are treated as one DICOM series (largest series wins, ≥8 slices); a lone `.dcm` is rejected as one slice, not a volume
+- Runtime: ZeroGPU (`large`); CPU staging/conversion runs quota-free, then one `@spaces.GPU(duration=90)` scoring call per case. Preprocessing (1x1x5mm resample, 96x256x384 pad/crop) is the upstream MONAI chain, reused verbatim (`transformers==4.48.3`; v5's loader crashes on this 2022-vintage BERT fork)
