EIGER measures z above 6 quasar clustering implying host halos near 10¹²·³ solar masses with duty cycles near unity: every massive halo shining at once, with no dormant majority. Yet JWST environment counts around comparable quasars range from 65-fold overdensities to average-density fields, and two z of 7.3 quasars show no excess at all. Strong clustering with enormous environmental scatter does not fit black holes that are tight functions of halo rank.
ΛCDM builds early quasars by abundance matching: the brightest black holes occupy the rarest halos, so clustering, environment, and duty cycle are all locked to halo mass. The model has no degree of freedom that lets quasars cluster like the rarest objects while individually living anywhere, or shine continuously while demographics demand dormancy.
SCT replaces the hot-dense-center with a superluminal collision cascade, and supermassive black holes with direct collision seeds: head-on geometries (impact parameter near zero) collapse thermalized debris into compact objects of 10⁷ to 10⁹ solar masses at the seeding epoch (P46), at locations fixed by where collisions happened, not by where halo-rank statistics peak (P56). Seed positions inherit the clustering of the collision geometry, which deposited structure correlated on the scales of the colliding pockets; that is why quasar clustering reads strong without requiring rare-peak occupancy, and why duty cycles inferred under the halo-rank assumption come out impossibly near unity: the clustering was attributed to halo mass that is not doing the work.
The environmental scatter follows from the same decoupling. A collision-seeded black hole can sit in a 65-fold overdensity or a near-average field, because the seed and its surrounding galaxy population were set by different aspects of the deposition geometry (P22, P25); under halo-rank matching that scatter is nearly impossible, under seeding it is generic. The dormancy bookkeeping also relaxes: seeds born at 10⁷ to 10⁹ solar masses need not accrete continuously to reach observed masses, so demographics and clustering stop fighting.
This is the same seeding mechanism behind the overmassive black holes at z above 7 and the Little Red Dots. There is no need to invoke unanimous duty cycles or super-Eddington conspiracies.
The registered kill: a complete z above 7 black hole census showing every system explicable by Eddington-limited growth from stellar-mass seeds formed below z of 30, with black hole mass tightly tracking halo mass and environment, removes the need for collision seeding and falsifies its signature. Sharper near-term: if enlarged ASPIRE and EIGER samples show quasar environments converging to a tight halo-mass relation with sub-unity duty cycles, the decoupling SCT predicts is absent.
