I apprehended it perfectly well; I'm still in disagreement, since my argument is unaffected.

It doesn't, and that's what you have missed. What I said is logically harmonious with all available evidence.
By observing three fish with the same solution for antifreeze, we know that three fish have the same solution for antifreeze. This immediately contradicts any claim that all unrelated species have different solutions for antifreeze, which makes them worthy of study. It's a "black swan".
As such, whatever mechanism has caused this has not been seen to work this way elsewhere. Therefore, saying "this mechanism is not seen to work this way elsewhere" is not remarkable as evidence.
It's now a neutral statement which matches our expectation, and can't therefore be evidence against the mechanism. It's certainly not evidence for another mechanism.
I could just as well say "I have only observed horizontal transfer in N other cases, and this is not one of those N cases, therefore it is not horizontal transfer". That would be wrong, but has equal logical merit as your claim.
