| # * resolver version -- helps maintain sleek size of the cache; | |
| # * lockfile hashsum -- as invalidation trigger of the correct granularity. | |
| # Since this cache only stores built *dependency packages* (not project code!), | |
| # we should invalidate/reupload it on each change to the dependency forest (≈lockfile). | |
| # | |
