Is "non-deterministic" the right description for this? I read it as describing an implementation where ordering is not preserved, but deterministically. Is that a misreading?

For example, polars internally hashes rows for some operations in ways that affect the ultimate ordering.
They do not guarantee stability of hashing algorithm or seed across versions and platforms.
(No complaints here! I agree ordering shouldn’t matter unless you make it explicit.)
