📖What it means

The line between two parts of the estate that may only be crossed in a stated way — an app never reaching into a droid, a chat never acting outside its permitted actions, a role never writing outside its lane.

📖Easily confused with

[{"term": "Contract", "distinction": "The boundary is the line; the contract is how it may be crossed."}, {"term": "Ringfence", "distinction": "A boundary separates parts of the system; a ringfence controls who may reach a paid vendor lane."}]
