Massless conformal check

These numbers vanish when $g_0\psi =\sigma \psi$ throughout the contributing past, although the individual response terms can be nonzero. For instance, if $\psi$ is supported in a post-ramp interaction plateau and observations are later than that support, then $I_g=I_{\sigma }$, while the iteration can be strictly positive.

The notation

denotes the degree-one classical evaluation justified by (eq:separation). It is not a state on the Wick algebra or a quantum expectation value. The diagnostics check signs and counting; they do not replace the variation proof.
