Let's see if we can replicate the issue! EDIT: Spoiler alert, we cannot.

@hoechenberger this appears headed for green. I was unable to replicate the caching issue on macOS, both datasets tested here appear to process in < 15s the second time. Ready for review/merge from my end. Happy to adjust CI requirements if you're happy (I folded the Style check into the doc consistency one since the only step we really needed there now was codespell, and knew we'd be adjusting requirements here anyway!)

Thanks! I also realized I cannot reliably reproduce on macOS. Sometimes the problem occurs and sometimes it doesn't. I usually work inside of a OneDrive folder, maybe this has implications...

It seems like it could for mtime but for hash it would be weird. It really seems like the file hash shouldn't change!

Let's just go ahead here and I'll report back sometime in the future if I run into this issue again :)
