JWST AGN samples at z of 4 to 11 show black holes of 10⁶ to 10⁸ solar masses sitting at 1 to 30 percent of their host stellar mass, versus 0.1 percent locally: overmassive by 10 to 100 times, with UHZ1's black hole rivaling its entire host (Maiolino et al. 2023; Pacucci et al. 2023). The ratios grow with redshift, inverting the model's host-first co-evolution sequence, and this is the population norm, not the outlier tail.
The model builds black holes last: stellar seeds inside assembled galaxies, growing by Eddington-capped accretion toward the local relation. That assumption makes high-z ratios necessarily at or below the local value, so a population sitting far above it, earliest where highest, has no place; the model can only impeach the masses or invoke seeds it cannot make.
SCT replaces the hot-dense-center with a superluminal collision cascade in which head-on geometries collapse thermalized debris directly into compact seeds of 10⁷ to 10⁹ solar masses (P46), while grazing geometries build the rotating stellar hosts separately and later (P31). The black hole comes first because the deposition channel that makes it is faster and more direct than the one that assembles its galaxy; overmassive ratios at high redshift are the unprocessed seeding configuration, and the local Magorrian relation is the late outcome of hosts catching up, not a birth law.
The demographics follow without tuning. Ratios decline toward low redshift as stellar assembly dilutes them, exactly the observed trend; abundance reflects the collision mass function rather than rare tuned halos, accommodating the JWST AGN counts and their Little Red Dot cousins; and no super-Eddington heroics are needed because the masses were deposited, not grown (P22, P23). The pre-existing matter reservoir (P25) supplies the dense natal gas the cocooned spectra record.
This is the same born-big channel behind the luminous z above 7 quasars, the quasar clustering excess, and the Little Red Dots: one seeding mechanism, four observational faces. There is no need to invoke tuned direct-collapse environments or hidden host mass at population scale.
The registered kill: a complete census of z above 7 black holes explicable by Eddington-limited growth from stellar seeds formed below z of 30, with ratios converging to the local relation at the highest redshifts, removes the seeding signature. The trend is the test: if deeper JWST mass functions show the overmassive fraction shrinking with increasing redshift, black holes grew into their excess and the born-big channel is falsified.
