      # Unfortunately this bug (https://github.com/ruby/ruby/pull/5646) prevents us from using
      # Ruby's native Module.const_source_location. Instead we have to fudge it by searching
      # for the file in the configured autoload paths. Doing so relies on Rails' autoloading
      # conventions, so it should work ok. Zeitwerk also has this information but lacks a
      # public API to map constants to source files.
