invariant
Always the same
Invariant describes something that remains unchanged under specified conditions or transformations.
In mathematics and physics, certain quantities stay constant despite changes to the system: The speed of light is invariant across reference frames.
In programming, an invariant is a condition that must remain true throughout execution.
More generally, invariant means unchanging or constant: an invariant principle, invariant throughout the process.
