dynamic choice set

Per Buchanan (@buchanan1979) via Shackle, humans plan actions based on an unknowable future but of imaginable possibilities.

This relates to active inference through (hidden) control states (@friston2012) that might or might not represent an action that an organism (agent) can actually perform. This also means that the action set must not only be different per person, it also must be dynamic intertemporally - as an agent imagines more possibilities they enter the action set
