The 1.0857 Geometric Anchor in CEERS2-588 Resolving the Solar Metallicity and Balmer Break at Redshift 11.04.

This paper resolves the maturity paradox of the high-redshift galaxy CEERS2-588 ($z = 11.04$) by applying the $1.0857$ geometric anchor framework. CEERS2-588 presents two significant observational anomalies that challenge standard cosmological timelines: a high stellar mass of $\log(M_*/M_{\odot}) \approx 9.1$ with near-solar gas-phase metallicity, and a prominent Balmer break indicating an aging stellar population within a 400-million-year cosmic window. By evaluating recent 2026 MIRI and JWST spectroscopic data through the Gross-Observer framework, we demonstrate that the observed Balmer break is a metric signature of a phase-locked system in structural equilibrium rather than chronologically old stars. Furthermore, the near-solar metallicity and rapid quenching within a small effective radius ($r_e \approx 450\text{ pc}$) are shown to be boundary conditions triggered when material density crosses the $1.0857$ synchronization threshold, removing the necessity for multi-generational stellar cycles.
