MAV-MCC — Held-Out Confirmation of a Recurrent Jet–Field–Matter Coupling Architecture in Centaurus A

Held-out confirmation after a public pre-analysis freeze: Centaurus A returns 4/4 CORE PASS plus a strong external matter-response PASS. This record reports the held-out confirmatory result of the MAV-MCC Coupling Corridor test in Centaurus A / NGC 5128, executed only after publication of the pre-analysis freeze v1.1-R1 (DOI: 10.5281/zenodo.22717577). The frozen CORE Judge contained four local axes: D — local dynamics / shock interactionC — local magnetic-field / polarization / coherence responseR — local radiative responseS — spatial specificity / control The preregistered rule was: CORE_PASS iff at least 3 of D, C, R, S receive PASS, with S required to receive PASS. External gas/matter response G was scored separately. Temporal causality T_G had zero CORE weight. Maser emission was frozen in advance as bonus-only and carried zero PASS/FAIL weight. Centaurus A returned: D = PASS_STRONGC = PASSR = PASSS = PASS_STRONGCORE = 4/4 PASSG = PASS_STRONGT_G = OPENMaser = BONUS_NOT_USED The frozen final class is therefore: CONFIRMATORY_PASS_PLUS_G This held-out result upgrades the coupling architecture identified during M87 discovery/development and refined during sacrificial calibration on 3C 264 from a source-specific pattern to a successfully reproduced cross-source phenomenological architecture under a public, pre-frozen Judge. The confirmed architecture is: local dynamics/shock → magnetic-field response → local radiative response → spatial specificity,with an additional external gas/matter response in the pre-identified Centaurus A Outer Filament. The claim is deliberately bounded. This result confirms the frozen Coupling Corridor phenomenology; it does not establish MAV-MCC as the unique physical explanation and does not falsify standard relativistic-jet, shock-acceleration, magnetized-plasma, or AGN-feedback models, which remain viable explanations of the same observables.
