Description

What I'd like to do is have a staging pull request action pull from the cache if it exists, otherwise, pull from the registry

So, I need to be able to check if the gha cache exists. Is there any prior art here?

Research direction

The issue names no files, tests, or entry points. Start by reviewing the existing staging pull request action and its cache and registry flow; define what cache-existence behavior is supported and what the fallback should be before identifying implementation work.
