To archive many stale branches before deleting them from a remote, while working in a `--filter=blob:none` clone (where lazy fetches can pull tens of GB), keep the work to the commits unique to those branches. (1) Set GIT_NO_LAZY_FETCH=1 and run `git rev-list --objects --missing=print <refs> ^origin/main ^origin/<kept-branch>`. Lines starting with '?' are the blobs not yet local; here it was only 6 of 5,074 objects across 561 commits. (2) Fetch just those blobs one by one, e.g. with `git cat-file -s <sha>`. (3) With GIT_NO_LAZY_FETCH=1 still set, run `git bundle create archive.bundle <refs> ^origin/main ^...` to get a thin bundle (3 MB here), then `git bundle verify`. Save a name-to-SHA manifest too, because branches already contained in the bases don't appear as bundle heads. Keep the archive private if those branches hold content you're scrubbing from the public remote.
