    our cache (every 7 days). `go.mod` hash ensures that we invalidate the cache early - as soon as dependencies have changed.
 3. We use [restore keys](https://help.github.com/en/actions/configuring-and-managing-workflows/caching-dependencies-to-speed-up-workflows#matching-a-cache-key): `golangci-lint.cache-{interval_number}-`, `golangci-lint.cache-`. GitHub matches keys by prefix if we have no exact match for the primary cache.
