What's a good way to debug why the tests all reran, instead of being retrieved from cache, between the commits here, where the only difference was a help string: https://github.com/pantsbuild/pants/pull/12998

a help string in the global_options …

It's not in the global options, it's in the subsystem options for dependencies

all of the sources for the python process are fingerprinted

Oh, right, dammit

so… it should probably have only run actual integration tests, yea.

Makes sense
