I've seen champion plugs break where the threads end.

Well, I have been around spark plugs for a few years so yes, seen it happen

Did compression/firing force it to separate or did it happen on removal?

Now you can braze an air fitting to the end for working on valves with motor installed. If you get crazy you could make a leakdown tester to attach to your new fitting.

Nope. Never seen that or heard of it in 35 years of working on all types of engines: aircraft, marine and automotive.

Made tools out of plugs--pistons stops for degree-ing cams and air plugs for changing valve stem seals, but never seen a natural failure like that.

Weird i didnt even know a plug could come apart like that

I have seen that happen. 20 years ago when my sister and her husband were dating, he was putting new plugs and wires in his car and on of the spark plugs broke apart just like that in the picture. Luckily my dad had an easy out and managed to get the part of the spark plug that was still in the cylinder head out.

I've had them snap off but never separate from the base. That's pretty rare but so is winning the lottery...buy tickets...

put some JB Weld on it and slap it back in the engine...

I've heard of that happening, never seen it personally though.

I had a the rear most plug, drivers side, on my '97 Ranger break off at the hex leaving the threads in the head. Took a friend and I 6 hours before we finally devised a way to get it out with an Easy-out. Had to lift the hood up to get the breaker bar and cheater pipe on to it with a contraption of sockets/chunk-of-hex-stock/adapters to get 2 square male ends together to have enough room to bend it all the way down to almost the radiator support before we hear a loud BANG, and it finally came loose. We were certain we were going to pull the head after that attempt, thankfully it came out. I still have it somewhere, it went on the wall of fame.
