Centaurus A hosts the third confirmed co-rotating satellite plane, found in under 1 percent of comparable simulated halos, aligned moreover with the host's own stream and shell debris (Muller 2018; Libeskind 2015; Pawlowski 2018). The Milky-Way-specific defenses cannot reach a giant elliptical thirteen million light-years away, and the model now owes three rare accidents plus an alignment.
Stochastically accreted satellites cannot share orbital geometry with each other, let alone with the host's tidal debris, so every coherence must be a separate coincidence. Three co-rotating planes around three different hosts, each with sub-percent probability, is the running bill for the assumption that satellites and host have independent histories.
SCT reads the CenA system as one debris field displaying its shared inheritance in two media. The host, its satellites, and the material now visible as streams and shells condensed from the same collision deposit, all stamped with the same J = μ(b × v_rel) (P31) and conserving it since (P32). The satellites co-rotate in a plane because they share the deposit's vector, exactly as the Milky Way's and Andromeda's do (recid 130, recid 131); the streams align with that plane because they are the unconsolidated remainder of the same field, fragments that never coalesced into bound dwarfs but still orbit with the inherited geometry. The alignment ΛCDM must buy as a second accident is, in SCT, the same purchase made once.
CenA's diagnostic weight is the universality claim: the registered prediction is co-rotating planes around essentially every adequately sampled host, and a giant elliptical far outside the Local Group is precisely the system that distinguishes a universal mechanism from local coincidence. The registered cross-tests extend here too: plane normals correlating with the local web geometry and the host's debris axes tracking the satellite rotation sense. The debris-field formalism is in Paper 6, From Chaos to Cosmic Collisions, with the inheritance ladder in Paper 5, From Chaos To Corotating Hierarchies.
Keystone economy: P31 stamps the field once; satellites and streams are two states of the same stamped matter. The third plane was not a third miracle.
Distance and velocity refinement of the fainter CenA dwarfs carries the local kill: if improved membership dissolves the kinematic coherence into projection, CenA returns to the standard fold and the universality claim weakens to two systems. The decisive test stays the registered census: LSST-era sampling of many hosts finding co-rotation at the sub-percent CDM rate refutes the shared-inheritance mechanism outright, while SCT equally requires the stream-plane alignment to survive deeper mapping; debris axes decoupled from the satellite rotation at high significance would break the one-field reading.
