SDK vocabulary

Distinguish recurring concepts in the guides and API contracts.

Read contracts unambiguously

Term	Meaning in this manual
Kit / installed SDK	The kit builds your project; the installed SDK lets it run with the game.
Mod / model / instance	A mod is a package; a model describes a signal type; an instance is a signal placed in the game.
Indication / aspect / reason	An indication associates a displayable result with its reason. Your enums give those values meaning.
Observation / snapshot	A copy of requested data at a point in time. Retaining it does not update it.
Unknown / absent / not requested	Three distinct situations described by each contract. None automatically means zero, false or clear.
Identity / generation	An identifier names an object in its documented context; a generation helps distinguish worlds or sessions. Revalidate references after loading.
Permission / appearance	A driving instruction and an image are independent. Changing an image does not create permission.
Ticket / terminal result	A ticket tracks a deferred request. Wait for or inspect its result; do not repeat a mutation merely because it is still pending.
Simulated time / real time	The game date follows pause and acceleration. Real duration measures work or waiting; these are two different time scales.
Assembly / activation / publication	Producing files, installing them for the next launch and distributing them are three distinct operations.
