Progenitor age is the primary physical driver of the host-mass and host-sSFR magnitude steps in Type Ia supernovae, with the mass step eliminated by direct age correction.
Synthetic stellar population models show TRGB luminosity varies by at most 0.028 mag from typical changes in alpha enhancement, age, and helium at fixed metallicity, confirming its robustness as a distance indicator.
