Yes; I think what I described matches that meaning?

Post-death, as in: "it's over," "activity has halted," "no more work being done."

Death does not necessarily have a bad/negative connotation. It's just the end of something.

This is in contrast to the original comment: "something that went so wrong you had to kill it." Death does not imply something went wrong or that it happened forcefully.

I guess "autopsy" generally is talking about "finding the cause of death" so maybe that has a more negative connotation ("something (bad) happened, causing death, let's find it").

Ah, words with their fuzzy meanings (:

Sure, that's true. It's not really relevant to people who don't speak Latin.

> It’s synonymous with autopsy!

This isn't true. I have no idea how you got here. In English an autopsy is a surgical procedure performed on a corpse for the purpose of identifying the cause of death. In particular, it's a noun. "Post-mortem" in the etymologically literal "after death" sense is an adverb or adjective identifying whatever it is as taking place chronologically after some contextually-specified death.

But, you seem to put some weight on the etymology of a word independently of its current meaning. In that case autopsy "literally means" to witness something personally, as opposed to hearing about it from someone else. (It's "self-eye" in Greek just as post mortem is "after death" in Latin.) Somehow I doubt that's what you had in mind...?
