Observable Consequences of the Rotational Invariant μ

T60 analyzes the observable consequences of the reduced antisymmetric rotational invariant \ (\) within the Q5 defect-sector operator framework. For a reduced operator of the form\ Q_=aI+bₓ+cᵦ+ R, theorem shows that expectation values decompose into symmetric contributions together with a distinct antisymmetric rotational quadrature proportional to\\, Tr (R). antisymmetric sector therefore contributes a phase-sensitive observable component that vanishes identically when \ (=0\) and becomes detectable whenever the reduced rotational invariant survives admissible reduction. The theorem further establishes that states exist which selectively detect the antisymmetric quadrature whenever the rotational contribution is nonzero. T60 is structurally important because it connects the reduced rotational invariant developed in T56-T59 to the observable-sector expectation structure. The theorem does not claim that all interference or observable asymmetry arises from \ (\). Rather, it identifies \ (\) as the unique antisymmetric contribution associated with the reduced rotational sector of the operator algebra. The result later became conceptually aligned with the selective-accessibility and reduced-sector survival principles formalized in the TA-series residual ecology arc. Status: solid for the reduced-sector expectation decomposition and antisymmetric quadrature structure under the stated operator assumptions; conditional on the admissible reduction framework and reduced-sector normalization conventions; speculative for direct physical observable interpretation beyond the internal operator model.
