Roche lobe overflow destruction of hot Jupiters clears all companions from the sub-Jovian desert inside ~4 days while most observed companions remain stable, unlike tidal disruption during high-eccentricity migration.
Dynamical tides exciting f-modes during high-eccentricity migration produce the hot Jupiter pile-up, Neptune ridge, and Neptune desert via orbital circularization and selective atmospheric mass loss.
MASCARA-1b atmosphere has solar metallicity, solar C/O, 2.5x solar refractories, and 2.3x solar refractory-to-volatile ratio, consistent with accretion between soot-H2O and H2O-CO snowlines.
