The key to answering that question is determinism. If the system’s behavior can be predicted perfectly, then there is no mystery left to explain, no information left which some unknown variable could provide
What matters is local determinism. You need to show that behaviour is predictable from factors under your control. If local determinism fails, it is hard to tell whether locality or determinism failed individually.
And showing that a system’s behaviour is predictable when N factors are held constant by the experimenter doesn’t show that those are the only ones it is conditionally dependent one. Its behaviour might counterfactually depend on factors which the experimenter did not vary and which did not naturally change over the course of the experiment. In general, you can’t exclude mysterious extra variables.

until then the results will generally work in practice.
Doesn’t really contradict what I am saying. In theory, I am saying, you can’t exclude mysterious extra variables...but in practice that often doesn’t matter, as you are saying.
