## 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.

`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

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.

Essentially we want to find a commit with the same *tree* state as the currently
