Introduction and the Enter interface discipline

The problem is to keep three statements separate:

The last statement must neither erase the failure nor supply an unconstructed quantum field observable.

Manuscript VII-A proves a classical repair for a specified action-level switch, fixed harmonic Cauchy prescription, and restricted gauge group CheungVIIA. Its repair does not extend to every compact gauge generator. We give the local proofs needed to place that construction in the conical laboratory of I-B CheungIB. VI supplies a documentary comparison for the unrestricted obstruction, not a premise of our argument CheungVI.

Relational observables and their perturbative expansions have established antecedents BFHPR,Frob. In particular, neither the existence of relational constructions nor previously computed gauge-invariant quantum correlation functions is claimed as a discovery of this paper. Our object has its own finite-time boundary data, switch prescription, and gauge domain.
