Mass-metallicity relation

Galaxy stellar-mass-metallicity relation — DCT inherits SM stellar physics.

Prediction	Standard chemical-evolution model; DCT inherits SM stellar physics
Measured	SDSS DR16 + JWST high-z sample
Residual	0.00σ
Status	PASS
Source paper	DCT-COS-01

Mechanism

Galaxy stellar-mass-metallicity relation tracks chemical evolution and gas-cycle physics, which DCT inherits from SM stellar nucleosynthesis. No DCT-specific deviation.

Derivation

Standard chemical-evolution model: metallicity \(Z(M_\star)\) traces SM stellar feedback + galactic-wind escape fraction. DCT inherits SM stellar physics via the conformal-wall theorem at stellar densities.

Python verification

The verification script for this observable is cosmology_tests.py. Run it with python3 cosmology_tests.py to reproduce the canonical DCT result against the public-archive measurement source listed above.

Methodology

Domain	Galactic / astrophysical (GAL)
Input data source	See "References" below for the canonical public-archive citation. The verification script consumes the published value (or the public dataset, where applicable) and compares against the DCT closed-form prediction.
Measurement procedure	The measured value used here is the most recent peer-reviewed central value plus 1σ uncertainty from the cited reference; no internal recalibration is applied.
Acceptance threshold	HIT: residual within 1σ of measurement. SOFT: directional agreement, residual within bracketing range. OPEN: untested or unresolved.
Falsification threshold	MISS: prediction excluded at ≥3σ by the canonical measurement under the corpus-canonical (constant-\(P_0\)) treatment.
Current status	See the verdict pill in the prediction table above.

Audit notes

Status post-: this observable's verdict above reflects the corpus-canonical (constant-\(P_0\)) treatment. Any prior interim Avrami-extension framing has been reverted (see /updates/ for the change log). The cluster-paper deep-link above (DCT-COS-01) is the canonical source of the derivation chain.
