So this is a thing that happens now
Cursor pretty consistently looses read access to folders. The workaround is that if I tell Cursor to grep it regains access and continues normally. This happens even when I freshly @link the folder or file again.
The drama continues:
But Cursor figures out it can run a touch and make the file, gaining access to it for a while.
If I didn’t know the workaround this would be a game-breaking bug. It’s still pretty annoying.
