The Galactic Center Excess, GeV emission peaking near 2 GeV and extending 10 degrees, spent a decade as ΛCDM's best dark matter annihilation candidate. The statistics have turned: the emission is clumpy, tracks the boxy stellar bulge rather than a spherical halo (Macias et al.), and the matching WIMP space is excluded by direct detection and dwarf-spheroidal nulls. The model is left choosing between an uncounted millisecond pulsar population and a particle that annihilates only where it cannot be checked.
A thermal-relic particle should annihilate brightest where dark matter is densest, making the Galactic Center the flagship target and the excess a natural claim. The assumption converts every diffuse residual into a potential detection, then forces evasive parameter gymnastics when the cleaner targets, dwarfs and direct detection, return nothing.
SCT removes the annihilation channel absolutely: no dark matter particle exists, so the excess must be astrophysical, and the framework registered that requirement before the morphology data arrived (P54). The bulge-tracking, clumpy character of the emission is the predicted signature, because the source population follows the stars. SCT also supplies the population with unusual ease: collision seeding produces compact-object populations early and abundantly (P46), and the pre-existing matter context (P25) gives the old bulge a deep inventory of recycled stellar remnants, so thousands of bulge millisecond pulsars are a natural census, not a rescue hypothesis invented for the excess.
The asymmetric stakes are the point: ΛCDM can survive either attribution, but SCT cannot survive the annihilation one, making the Galactic Center a genuine falsification arena rather than an interpretive preference. Every swing of the statistics toward stellar tracers, every dwarf-spheroidal null, and every direct-detection exclusion is the universe repeatedly endorsing the no-particle ledger.
This is the same universal-null stance behind the 3.5 keV deflation and the positron excess attribution. There is no need to invoke a particle that performs only at the most confused sightline in the sky.
This resolution is developed in Paper 12, From Chaos to Coherent Gravity, with the underlying mechanism in Paper 11, From Chaos to Cosmic Collisions.
The registered kill: confirmation of the annihilation origin, a smooth spherical component irreducible to point sources with the spectral and morphological scaling annihilation requires, or a correlated signal at the same particle mass from dwarf spheroidals, would be a dark matter detection and would falsify SCT outright. Conversely the pulsar inventory is checkable: MeerKAT and SKA failing to find the required bulge millisecond pulsar population at radio wavelengths would strain the astrophysical reading SCT mandates.
