immutables

Things never altered

Things that cannot be changed or altered.

In programming, immutables are data objects whose state cannot be modified after creation—strings in many languages, frozen objects, constants.

The term appears in philosophy and theology for eternal truths or divine attributes beyond change.

The immutables of the contract were non-negotiable.
