Hi @DaviRain-Su, sorry about this — the PR was accidentally marked as merged but your changes (Pi, Hermes, Factory platform support) didn't actually make it into main. It looks like a GitHub merge state issue caused by branch alignment.

Unfortunately the original commits are no longer available in the PR or your fork's main branch. If you still have them locally (check git reflog), could you push them to a new branch and open a fresh PR? We'd love to get those platforms added.

Again, really sorry for the confusion!
