1623 — The Source Cubic Momentum Channel Lands on the Statistical Axis of the Second-Rees Cone
Frozen source component
For an observed momentum occurrence , retain the two ordered internal occurrences , momentum conservation, and the finite-EFT domain. Entry 1616 fixes the source production amplitude channelwise as
The first-order state component is
Reduced covariance map
Trace the two labelled internal occurrences. Distinct momentum labels are orthogonal, so cross-channel interference vanishes. Endpoint interference remains inside each channel. Consequently,
and
The anomalous first jet vanishes because its operator changes observed particle number by two, whereas the vacuum and cubic production component differ by three total quanta.
The ordered occurrence factor cancels the identical-pair channelwise, as in Entry 1617. Entry 1618 supplies the positive symmetric finite-EFT measure.
Result
The source cubic production channel lands on the statistical axis of the Gaussian second-Rees cone:
Saturation occurs exactly when
for almost every admitted internal channel.
Thus no interference term survives outside the positive labelled pairing. The only destructive interference is the source-derived bulk/surface cancellation already contained in .
Qualifications
The finite checker audits complex endpoint amplitudes and occurrence normalization. It does not numerically integrate a model-specific continuum kernel. Coincident internal labels form special strata and remain occurrence-resolved before physical trace.
Architectural consequence
For this actual cubic source channel, the abstract coefficient mechanism of Entry 1622 is realized without a new carrier cell:

Next falsifier
Add a nonzero Gaussian first jet to the source state and compute the mixed cubic–Gaussian second grade. Test whether all terms linear in the cubic channel are Hamiltonian/coherent tangents while the genuinely statistical remainder is still a positive labelled Cut norm. Preserve the occurrence labels and do not infer the answer from the vacuum channel.
