3514 — The Fourier–Tate Cocycle Is Meromorphically Trivial but May Have No Admissible Global Frame
Hilbert theorem 90 trivializes the reflection cocycle in the meromorphic function field. The trivializing frame may nevertheless contain zeros, poles, monodromy, incompatible Real structure, or unbounded completion multipliers.
A fixed-point sign (-1) cannot be removed by a nowhere-vanishing holomorphic frame. Odd logarithmic winding obstructs the elementary half-log frame.
The research-bearing gate is therefore admissible-frame triviality: nonsingular, Real-compatible, source-normalized, and boundedly invertible on the completed carrier.
