The question and the permitted endings

XV-D XVD audited the supplied record item by item and found that the data defining the full joint characteristic operation for the frozen six-branch graph were not in it. XV-E asks:

Can the frozen six-branch operation be defined on the specified domain, extended to tests meeting the characteristic locus $N$, and made independent of presentation within the inherited correction class?

Exactly one of three endings is permitted for the graph-level problem: Constructed through descent; Obstructed in the frozen class, with the class proved exhaustive; or Unresolved at a named gate. Failure to recover a source is not an analytic obstruction. Successful descent would not be quantum admission.
