Lean proofs of the ALWZ and Rao–Bell–Chueluecha–Warnke sunflower bounds, robust-sunflower upper and lower bounds, the BCW spread and satisfying results, and the classical Erdős–Rado theorem. The submission compares ten explicit finite statements, including second-moment and Janson routes to the ALWZ bound.
