+
+## Derivation
+
+- Downloaded member: `roi_timeseries_data.zip`
+- Atlas member: `roi_timeseries_data/vfb_nn/vfb_nn_Original.nii.gz`
+- Functional member: `roi_timeseries_data/functional/brain03gc6m.nii.gz`
+- The region series is the unweighted mean of the raw int16 functional volume over every nonzero atlas label, computed in pure numpy.
+- The companion AFNI/FSL pipeline erodes each ROI and motion-corrects the functional volume before averaging; that pipeline is **not** reproduced here.
+- `times` is a frame index; the volume header carries no repetition time (pixdim[4] = 0), so the sampling rate is unconfirmed.
+
+## Artifact
+
+- `region_timeseries.npz` (sha256 `b661f565be6c86fc3e3e2a046d03efb0de0ea4b26c5a7da2069b212a1b25c622`, 1283088 bytes)
+- Regions: 73; time points: 4000
+
+No biological claim is made. This is a provenance-first derived input, not a reproduction of the published functional network.
