GHZ2 at z=12.3 shows a stratified ISM with coexisting density zones and needs an additional hard ionising component beyond pure radiation-bounded stellar models to match its emission lines and variability.
JWST data on LRDs and LBDs show AGN-like excitation, strong Lyα with broad components, and X-ray weakness, implying clumpy or equatorial geometries around growing black holes rather than complete gas envelopes.
Rapid halo growth in SEEDZ simulations enables heavy black hole seed formation via supermassive stars at a comoving number density of 0.1 cMpc^{-3} by z=10, with most seeds in near-solar metallicity gas.
