These were dealer's verbatim words: no signs of leaks, (drain plug, filter etc) no fouling on plugs.
Tcoat, you say it would be smoking like it was running on coal to be using that much oil, but others say that's perfectly acceptable oil usage (1qt/1000miles).
My FA20'd WRX ran for 2 years without burning a drop of oil. Something ain't right.

That is under heavy use which you said that you did not do.
The oil change interval for a 2015 is every 6,000 miles. If yours was done to schedule you would have had a change at 18,000 miles. Since you said you are at 20,000 miles and there was one quart then you went through 2.25 quarts per 1,000 miles. It would be sending smoke signals seen for miles.
Even if it managed to burn through that much in 2,000 miles it does not erase the fact that you should have been checking. If checked you should have seen it was a quart low after only 500 miles after the change and down 2.25 only 1,000 miles after. I would hope that you would have questioned the drastic drop at that point not after the engine blew.
I am not trying to be a **** here but I see no case to be made. The mechanism of loss does not mean anything in this instance. The manual (and common car maintenance practice) says to check your oil on a regular basis. If you had checked it you would have seen it was low and could have dealt with it. The moment that you drive a car off the lot it is your responsibility to check the oil and no matter what the cause of the loss is it is up to you to have it addressed before catastrophic failure.
