Stacked JWST spectra show weak MZR slope evolution to z~5 with declining normalization, steeper MZR beyond z~5, and emerging shallow FMR anti-correlation by z~5.

Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.
New stack-based strong-line calibrations from ~1500 spectra yield mass-metallicity relations at z=1-10 with decreasing metallicity toward higher redshift and no slope change, plus 50 EMPG candidates at 1-4% solar metallicity showing large scatter and opposite sSFR trends.
JWST auroral-line selected galaxies at high redshift show an MZR slope of 0.38 with selection biases favoring high-SFR low-metallicity systems, while stacked non-detections lie closer to the fundamental metallicity relation.

A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at $z\sim6-8$
Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.
