Research direction

The issue identifies FIRRTL port bundle flip fixups but names no source file or test. Locate the FIRRTL transformation responsible for port bundles, reproduce the shown input, and trace how flipped ports are handled. Done means the example transforms from an input bundle with flips to an output bundle with non-flipped ports, with a regression test if the relevant test location is found.
