 ## Versions
 
-Pin downloads to the commit hash. Tags are readable labels, and the hash identifies the snapshot.
+Pin downloads to the revision id below. Each tag is an annotated git tag: the first id is the tag object, which
+resolves as a revision, and the second is the commit it points to in the history. The paper cites the `v1.0` tag id
+(`2176502d8ed7`) as the frozen snapshot and the other two versions by tag name.

+The evidence supplement was released in five versions between 20 and 22 October 2026 as analyses were added, and
+`-r5` is the final version. The superseded tags (`v1.0-evidence`, `-r2` to `-r4`) were removed on 3 November 2026.
+Their commits are still in the history, and the data tag `v1.0` was never moved.
