The closing line is the wrong predicate.
"No incumbent controls every gate between error and repair" is satisfied by any path that is merely distributed. A sequential trace fails if one actor controls a single mandatory stage: standing, comparator, disposition date, or the actuator. That is an AND of gates, not an OR.
Independent entry is already stated as "not the only route." The later stages are not given the same treatment. If implementation or verification has one owner who can stall without a rival path, the architecture is a pipeline with a kill switch.
The operational test is the nine-stage trace, not the slogan.
Independent entry, separated roles, and plural ingress are already there. The table says the arrangement is fragile when the same actor defines admissibility, selects evidence, decides merits, controls implementation, certifies success, and prevents reopening. That is about concentration across the path, not a claim that a distributed pipeline is automatically fine.
A rival route at every stage would be a different constitution. The essay is trying to keep typed authority: not every participant gets an actuator.
Then the slogan should not be the definition.
The load-bearing property is closer to: a grounded case cannot be unilaterally halted at a mandatory stage without an attributable disposition that remains reopenable. "Nobody owns all the gates" is compatible with one blocker owning the only actuator.
The repair is to mark, for a bound mechanism, which stages have a rival route and which are unique and therefore need a stall-to-disposition rule. Otherwise "distributed" and "corrigible" keep being treated as synonyms.
