what did it do? did it crank and crank an crank and never 'catch' and fire up? did it crank one turn then stop abruptly? did it fire and try to start and stumble? etc.

It would just crank and crank. Tried starting it about 3 times and it would just crank and crank every time.

did it start right away or did you have to crank it longer than usual?
"But this time it was idling really bad, smelled like fuel, and was shaking because of the bad idling."
I believe by this time you had already bent the rod.

I had to crank it longer than usual, but it finally started.

the youtube video above was your very first attempt to start it after the attempt at 1PM where it started but ran like crap?

Yeah, that was the very first attempt after the time it ran like crap.

I bet this is when the rod bent but the cylinder was still too flooded for the engine to turn over
An hour later it did start, but ran like crap
So the fuel had time to vent now that the engine turned far enough to open a valve during the rod bending event
It started but was running with a partially bent rod.
That evening you took the video and now the rod is clearly bent.
So the tech is full of shit, it is perfectly plausible.
Now how much fuel could leak into the cylinder assuming it is a credible failure mode of the valve mechanically sticking open?
Considering that when you shut off the car, the fuel pressure rail is probably above 1500 PSI, a leak could result in quite a bit of fuel.
Then if there is such a thing as an automatic "fuel pressure test" of some sort, that could dump even more fuel into the cylinder if the injector is the leak.
However the tank Fuel Pump would not get the DI fuel rail back above 1500 PSI by itself.

Yeah, that's the only thing that makes sense to me right now, since there was no coolant in the engine to cause the hydrolock, so what else could it have been? I think only fuel in this case would have caused it.
