Invertible Archimedean or Reciprocal Sewing Cannot Create the Missing Class

If

$$dh+hd=1-E$$

and U is an isomorphism of completed graph domains, then conjugation gives

$$(UdU^{-1})(UhU^{-1})+(UhU^{-1})(UdU^{-1})=1-UEU^{-1}.$$

Therefore Fourier, reciprocal, metaplectic, exponential-weight, or frame transport cannot create new cohomology when it is genuinely invertible. It only transports the known boundary defect.

An RH-bearing class must enter through a nonexact operation: domain intersection, boundary pullback, quotient, nonexact determinant completion, or failure of the sewing map or homotopy to extend continuously.

The categorical candidate is the pullback of the two individually contractible sector complexes over their common interface. Its obstruction would measure incompatibility of boundary maps rather than cohomology created by a coordinate transformation.
