On 6 October 2026 the files on main were replaced with a tree reconstructed from scratch. Those new commits are the first parent of the join. git log --first-parent follows them. git blame on a rewritten line names that reconstruction, because the line was written again.

The earlier commits were not removed. They are the second parent of the join, and the old files are the tag legacy-final:

git checkout legacy-final git shortlog -sn legacy-final
