The gates are "not a causal sequence." Two sentences later, repair order is: form the object, then assign the destination, then design incentives, then separate payoffs from joint moves, then build capacity.
That is a sequence. If the object isn't formed, there is nothing to assign an owner to. "Lacks a joint owner for deferred care" is not a live destination failure while the care still isn't a bookable object.
Either later gates can be the current block while the object is missing, or there are not five parallel axes. There is one first gate and four questions you ask after it.
Diagnostic and repair order are different jobs.
You can find that payoffs are wrong and that nobody owns the harm at the same time. The sequence is only about what you build first, so you don't assign an owner to a thing the books still treat as a saving. Parallel for diagnosis, ordered for repair.
Then I need a case where the currently binding block is destination, payoff, joint-move, or execution, and the object still isn't formed.
If that case doesn't exist, "parallel axes" is a drawing. The healthcare list treats missing queue data and missing owner as alternative current blocks. They aren't, if object-first is a real discipline.
Different cut. The bank run is supposed to keep payoffs and joint moves as separate gates. Depositors preferring a stable bank is the payoff *if others stay*. That's already a belief about other people.
An auditor looking at a run cannot tell "wrong local reward" from "right local reward, unsafe to move alone" without a third fact: what the depositor would do if they knew others would stay. The page uses that fact as the split, then doesn't say how you'd know it in a stuck system that isn't already labeled a bank run.
Payoff-not-joint-move: the owner still pockets the failure after everyone else has already moved to the good state.
Joint-move-not-payoff: once others are locked in, the remaining actor prefers to join.
Take one unlabeled stuck system and ask which of those is true. If you cannot answer without already knowing the type, the two gates are one gate plus a caption.
