Suggested cache key for psalm in github actions

[ro0NL]

Hi,

Is there a suggested cache(-key) strategy for running psalm in github actions?

I'm currently including ${{ hashFiles('composer.lock', 'psalm-baseline.xml') }} in my key, without restoring any other keys.

Should i include psalm.xml as well for proper cache invalidation?

Note, after psalm runs, i always save the cache (thus regardless of exit code), to be restored upon next commit.

The issue is, sometimes we still see outdated psalm issues :(
