But in all cases the teacup does not actually change its “policy”, which is just to transmit heat to the inside of the cup according to the laws of physics.
This kind of description depends completely on how you characterize things. If the policy is “transmit heat according to physics” the policy doesn’t change. If the policy is “get hotter” this policy changes to “get colder”. It’s the same thing, described differently.
