Reprojects abundances of 199k stars into 4 patterns, identifying enrichment pathways with strong chemo-spatial, age, and vertical correlations plus a transition at ~6 Gyr.
Abundant early heavy seeds plus frequent mergers produce the massive black holes seen by JWST at z>9 and yield about four LISA events per year at z>=8.
Bursty stellar feedback produces systematically flatter metallicity gradients than smooth feedback in high-redshift galaxies across multiple simulation suites.
