Remark: Family 203. Donovan's conjecture over fields and discrete valuation rings

Proves Donovan's conjecture: over each fixed algebraically closed field of characteristic $p$, blocks of finite groups with bounded defect-group order have only finitely many Morita-equivalence classes, for every prime $p$. Also proves the integral form over each fixed complete mixed-characteristic discrete valuation ring with algebraically closed residue field.

The authors are OpenAI. This companion does not verify the proof. The claim is not a theorem of the Enter series and not a premise of any registered sheet. It does not close O.1. O.1 stays NOT_CLOSED. It is not a de Sitter state and not the QdS external-leg scheme. No quantum coefficient is admitted. No compilation is asserted.
