FileFollower
Up and coming: shot check knows this class and its members today, and programs run it once the native runtime lands.
Up and coming
Follow a growing file line by line, and carry on where you stopped after a restart.
PathHandler:FollowAsync(offset) gives one, a child of that PathHandler. It looks at the file every Interval seconds and hands over each complete line; a half-written last line waits until its end arrives. With no offset it starts at the file's current end, so only new text comes; 0 starts at the beginning. Save Offset and pass it back to carry on.
