The blockwise Alperin weight conjecture

Claims l(B)=∣Wp(B)∣l(B)=|W_p(B)| for every prime pp, finite group GG and pp-block BB, including the Q=1Q=1 case. Consequences derived: l(B)≥l(b)l(B)\ge l(b) for the Brauer correspondent bb, equality for abelian defect groups, the Sylow normalizer inequality for Brauer character counts, and principal-block bounds of Hung, Sambale and Tiep. The proof uses chain inversion and powers modulo commutators to reduce to counting tuples in groups with trivial OpO_p, then proves the needed pp-power divisibility via moduli of marked genus-one covers. It is an equality of cardinalities only: no natural or equivariant bijection, and no inductive condition for simple groups, is established.
