Pantheon Plus and the Audit-Proof Shape Test of Canonical Field Cosmology

This paper examines whether the canonical field-mechanical cosmology of the current Phoenix Axiom is compatible in its basic form with a binned Type Ia supernova working dataset referred to here as Pantheon Plus. The test is not a complete foreign-model fit, but a cleanly separated shape test of the canonical logarithmic distance relation against the adopted data points. The analysis is formulated as TFD-internally audit-proof because it uses only the binding canonical quantities and introduces no free adjustments. The central result is clear: the TFD curve reproduces the basic curvature of the data, but remains systematically below the adopted dataset in absolute terms. The paper therefore shows, on the one hand, a fundamental shape compatibility of canonical field cosmology and, on the other hand, an equally clear remaining residual structure. This residual is classified in a theory-adequate way as an open difference term with TFD-internal interpretive possibility, not as an already finally decided external conclusion.
