In old school ML a pathological solution is often a collapse of some kind due to an underspecified objective. Maybe one parameter explodes or the model predicts "0" for everything
I read this as "the code is working as intended but the bug is an artifact of the original design"
I genuinely have no idea what it is meant to mean in the context it uses it. Load-bearing etc is annoying but roughly understandable, some of the opus5 classics are completely out there.
I'm a native English speaker as well, I shudder to think what a second language speaker would do (even if they were very confident with the language!).
This is a term fellow devs have been using for years and years and my brain just cannot come to re-index its meaning. So I am immediately distracted by the context switch to sociopathic liars and related psychology.
