No, and most people growing Himalayan plants haven't been there.

But that begs the question... so, if it had actually been
Corydalis cheilanthifolia, which is from China, should I assume that would mean you'd gone there and collected it yourself?

Just kidding... but seriously, it's a fairly common plant in cultivation, so I'd guess you bought it (mislabelled) somewhere. I dunno... you tell me?
