| # When a cache is created by a workflow run triggered on a pull request, the cache is created | |
| # for the merge ref (refs/pull/.../merge). Because of this, the cache will have a limited scope | |
| # and can only be restored by re-runs of the pull request. | |
| # | |
| # This performs garbage collection on cache keys associated with a closed PR. | |
