Agent, Flight, Combat, MoveTo and Follow write only Ship.Command. Entities with no agent apply first, then each agent applies right after it decides. A pilot reads its own pending designation and aim item back from its command; FireControl gains Refuses/AgentFires/HitProbability overloads that take them.
