## Problem
If the `git` garbage-collects any of the commits to which services are pinned,
and that service attempts to deploy/redeploy, it will fail.
If `git` garbage-collects any of the commits to which services are pinned, and

`git for-each-ref --contains $SHA` will report all of the refs that can reach
some commit, `$SHA`. This may be things like:
- `refs/replace`: `git-filter-repo` artifacts
some commit, `$SHA`. This may report things like:
- `refs/replace` (i.e. `git-filter-repo` artifacts)
- `refs/stash`
- some local branches
- some remote branches
One solution might involve avoid garbage-collection. But if any of our pinned
commits contained sensitive cleartext we will *want* to ensure that `git` purges
these.
