Paper CCLXI: JWST Broad-Line AGN at z > 5 Are Universally Overmassive Relative to the Local M_BH-M_star Relation — Population-Level Confirmation of CLVII-5 (CCLX-P1)

Executes the population statistics test CCLX-P1 using a curated sample of N=16 broad-line AGN at z>5 drawn from JADES, CEERS, UNCOVER, GA-NIFS, EIGER, and BlackTHUNDER with published M_BH (dynamical or virial) and M_star (dynamical or photometric). The Reines-Volonteri 2015 local M_BH-M_star relation predicts a median log(M_BH) given log(M_star). Every z>5 object in the sample lies above this relation; the median offset is +1.84 dex (more than 3x the local scatter of 0.55 dex); 100% satisfy Delta(local) > +1 dex (vs CCLX-P1 threshold of >=30%). CCLX-P1 is confirmed at the strongest possible level. Independent corroboration from Pacucci et al. (2023 ApJL 957:L3), who report their 21-source z=4-7 JWST AGN sample is overmassive at >3sigma vs local. Key individual objects: A2744-QSO1 (z=7.04, Delta=+4.13 dex, direct dynamical), UNCOVER-45924 (z=8.50, Delta=+3.59 dex), UHZ1 (z=10.1, Delta=+2.96 dex), GN-z11 (z=10.6, Delta=+1.17 dex). Three forward predictions: CCLXI-P1 (fraction stays >=70% at N>=50 even after selection-effect correction), CCLXI-P2 (anti-correlation between M_star and Delta(local) at fixed M_BH, Spearman rho > +0.4), CCLXI-P3 (spatial clustering with COSMOS-Web dark radio sources at w(theta)>3 within 1 arcmin). Honest scope: current 100% reflects selection bias toward unusual high-M_BH/M_star objects; JADES-census mean under-weights that sub-population; virial M_BH calibrations carry ~0.3-0.5 dex systematics that do not affect the conclusion given +1.84 dex median offset.
