Indeed -- to me, it sounds like contracts (when broken) are meant to
have "defined but nevertheless erroneous behavior", which is a concept
that e.g. Rust uses.

But regardless of whether a broken contract ends up implying a program
is "incorrect" or not, we would soon start seeing systems relying on
contracts aborting nevertheless... :)
