3192 — The Existing Tail Bridge Does Not Fill the Fifth Wall
The completed theta zero lifts canonically to an antidiagonal two-tail state, but that state solves the singular pencil
not an eigenvalue equation for a fixed skew-adjoint realization. The null spectral channel is the source-essential constant channel. It cannot be deleted, and symmetrizing its triangular coupling introduces new reverse incidence.
Thus the fifth wall requires a genuinely new constructor or a theorem for the singular relation; it is not already supplied by the tail augmentation.
