Your captain hands over cleanly
A chat meant for your captain is turned away by a Mac that stepped down, and a view read under the old captain starts fresh.
When you send a chat or start an automation on the Mac that is your captain, Bandicot marks it as meant for the captain. If you moved the captain while it was on its way, the old one turns it away and says so in your activity, instead of quietly running it on the wrong Mac.
Anything following a session from another device keeps a bookmark of where it was. That bookmark now names the captain it was read under, so after a change the follower reads the session again from the start rather than trusting numbers from another Mac's log.
A chat you send to a particular Mac by name runs there as before.
