I am aware that beej's guides are typically quite comprehensive, but the vast nuances of git truly eluded me until this.
I guess Jujitsu would wind up being a much slimmer guide, or at least one that would be discoverable largely by humans?
The universe doesn't owe you an easy 10 minute video solution to everything, it's an annoying educational expectation that people seem to have developed. Some things are just that difficult and you have to learn them regardless.
I can teach someone who has never even heard of source control how to use Perforce in about 10 minutes. They will never shoot themselves in the foot and they will never lose work. There are certainly more advanced techniques that require additional training. But the basics are very easy.
Git makes even basic things difficult. And allows even experts to shoot their face off with a rocket launcher.
Git sucks. The best tool doesn't always win. If MercurialHub had been founded instead of GitHub we'd all be used a different tool. Alas.
It was a disaster. Literally the most important thing for any VCS tool is to never ever delete file I don't want deleted. No more Jujutsu for me.
Someday someone will invent a VCS tool that doesn't suck. Today is not that day.
It is _exceedingly_ hard to lose files in jj, it's actually emotionally frustrating reading the line "most important thing [..] is to never ever delete file" because that's the whole shtick in jj with the oplog and whatnot - so something like nuking secrets completely from a jj repo is a bit of a chore.
Can you file a bug at least? A repro of some sort?. Or at least show us what is it what you did, `jj op log` might be enough to deduce what happened.
Also check out `jj op log -p`, your files might very well be in history, especially if, as you said, jj status took a long time (presumably snapshotting those files that got lost)
