And yet, the entire Theory of Evolution *depends* on ancient Fish having an immune system that no fish DNA on hand supports.

If you mean a common ancestor of humans and modern fish, perhaps. But loss or modification of function is not code skipping.

Indeed. However, genetic functionality in one ancestor, not in any intermediary, but found again in a child species *is* code skipping.

And unless coral/human immune systems are ever found in Fish DNA, Evolutionary Theory will be forever dead in the water.
