📖What it means

The promise one piece of the estate makes to another — what it will accept, what it will return, and what it guarantees. Breaking a contract quietly is how a caller starts getting wrong answers without any error appearing.

📖Easily confused with

[{"term": "Boundary", "distinction": "A contract is the agreed terms; a boundary is the line the terms are agreed across."}, {"term": "Policy", "distinction": "A contract binds two components; a policy binds the whole system."}]

📖Also called
