Euhm what the hell are you on about. This is a fixed output derivation. The output per definition is reproducible. It either returns a value that matches the hash or it fails.

The whole point is that it allows introducing controlled side effects as long as the output is reproducible.

Bur you're extremely annoying to talk to so I'm not gonna continue engaging. Probably an LLM

The outcome isn't even reproducible if GitHub is down, so like multiple times a week now. And FODs routinely break because of the dozens of leakage modes in the evaluation cache (if flakes are involved), the dozens of races (mostly TOCTOU or adjacent) on the `sqlite` interface and other store-adjacent bugs (`ssh-ng` is especially broken, that's actually the biggest blocker to floating CA at the moment), and so it is very easy to change the declared hash of a fixed-output derivation (for example, you're iterating on the upstream artifact) and have an old one stuck in cache/store because the `Aterm` driving the NAR calculation doesn't trip a fetcher invoke.

This stuff doesn't work, and mixing in ambient environment state is the cross product of the current amount of broken with now it's not even the same on my laptop and desktop.

If you know of an LLM that understands this stuff in this kind of detail, I would be in your debt for a referral, because I sure as hell wish I didn't have to know all this stuff.

And if it's annoying to make vague claims without supporting evidence and have them refuted by concrete arguments with specific details cited than HN may not be the place for you. Being right matters here. I haven't been rude, or made it personal (vis-a-vis "you're extremely annoying" which I don't appreciate).

I don't get the personal attack on this. I'm talking facts about technology.
