> The public key is different in the request and response here, that's my copy-paste fail.. I had 'lost' the original private key and wanted to provide a valid pair for someone to troubleshoot with. As a result I amended my output here to show the new public key being sent in the ADD_ONION, but forgot to update it in the returned response from my earlier attempt. Sorry if it added confusion.

I've created https://gitlab.torproject.org/tpo/core/tor/-/issues/40378 to
track this down.
Thanks a lot for the detailed report!
