+Consequences, all of which apply to this mirror and to anything derived from it:
+  * Share       - redistribution is EXPLICITLY permitted by the license text, which
+                  is why this mirror exists.
+  * NonCommercial - research use only, no commercial use. The OSF wiki adds:
+                  "Ulas.bagci@northwestern.edu should be contacted in case of
+                  commercial interests with the data."
+  * Attribution - the citation below is mandatory.
+
+There is no ShareAlike term, so derivatives are not forced to CC BY-NC 4.0, but this
+mirror is tagged CC BY-NC 4.0 to match the source.
+
+TWO LICENSING TRAPS worth recording:
+  1. The OSF node's machine-readable `node_license` field is set to "Other", whose
+     text is only "Please see the file named license.txt in the OSF Storage of this
+     project". Any tool that reads the OSF API license field learns nothing.
+  2. The medsam-datasetlist.github.io curated list records this dataset as "GPL 3.0".
+     That is NOT corroborated anywhere: the PanSegNet GitHub repo carries no license
+     at all, and the authors' own LICENSE.txt says CC BY-NC 4.0. Most likely the OSF
+     node carried a GPL-3.0 selection before the LICENSE.txt was added (modified
+     2025-07-29). Treat CC BY-NC 4.0 as authoritative; do NOT rely on the GPL claim
+     to assert commercial rights.
+
+Note also that the *article* is CC BY 4.0 (Elsevier VOR) while the *data* is
+CC BY-NC 4.0 -- they are not the same license.

+This mirror redistributes the official release unmodified: the NIfTI files are
+byte-identical to the OSF archives (hard-linked, never rewritten or recompressed).
+Added files are metadata only (jsonl indices, a patient cross-reference CSV, this
+notice and the dataset card).
