Post #4271196

The AI code-review bot my company uses just wasted 2 hours of my time. It reported a bug in cache logic in a PR. I didn't change caching, but it's a Rails app so unexpected invalidations and indeterminate staleness can both happen. Report said it doesn't invalidate properly, so I investigated but couldn't find the bug. It was talking about the fact that these cache entries can be stale for up to 2 minutes, which is intentional. There's even a comment about it right above my changes.
