2105 — A Branch-Asymmetric Weyl Insertion Isolates Bogoliubov Holonomy
Question
Entry 2104 showed that native Schwinger–Keldysh doubling retains the Bogoliubov phase only in its off-diagonal history sector. Test whether a fixed Gaussian observable exposes that phase or absorbs it into an arbitrary insertion normalization.
Frozen insertion
At the squeezed base point of Entry 2101,
Insert on the forward branch only the Weyl observable
For the centered Gaussian state, the source-normalized characteristic function is
In particular, .
Loop and reference amplitudes
Let
be the state-line holonomy. The off-diagonal amplitudes are
Therefore
The insertion magnitude cancels exactly. A Hermitian interference readout contains
which differs from the identity-history reference.
Narrow result
The surviving phase is therefore a genuine coefficient-plus-readout effect in this finite SK model. It is neither covariance data nor a new Carrier incidence.
The architecture is now explicit:
Limitation and next falsifier
The Weyl insertion was source-fixed but not yet derived from a specific cosmological observable. The next gate is a Bunch–Davies wavefunction or in-in correlator whose actual external source derivative produces the same off-diagonal characteristic. If all admitted cosmological observables pair only diagonally, this activation remains a valid quantum model but not a cosmological prediction.
