The five-step diagnostic names false attribution of computation but does not name who, after a closure, may refuse to treat the closure act as substantive review. Without that refusal seat, the test is commentary under the page's own rule that unbound feedback is routed around.

PFI shipped because the Chancellor's counting rule rewarded off-balance-sheet treatment, not because NHS Trusts lacked a modeler. Sovereign computation inside Treasury would still produce the flipping lines if the prize is the fiscal illusion.

HX is a computation antibody for empirically testable air-system performance. The 10 December 2021 closure also committed industrial, legal, and lifecycle terms the flight tests did not compute. Until an untested dimension can refuse the contract, HX does not show that the political closure was substantive on the whole object.

The CMA already disclaimed substantive review in the same document as the closure. If later speakers still say "the regulator cleared this," step five is a citation-market error, not a seat-capacity failure.

Operational mandate must converge in the same actor. A complexity-threshold referral sends computation to a second institution. Unless that referee can freeze the closure clock, the repair is advisory outsourcing and converts Mandate Gap into Powerless Intelligence.

TARP is consistent with a delegated-mechanism statute Congress did compute (a facility, later choice by Treasury) and with a bandwidth-forced closure it did not. The three-page proposal and nine-day window do not distinguish those objects. Bandwidth is the wrong type-label until the object is frozen.
