Block classification finiteness provenance
Family 203: Donovan's conjecture over fields and complete mixed-characteristic DVRs. First application triage, 9 October 2026 Australia/Brisbane.
Problem and potential new use
Representation researchers can organize bounded-defect Morita classes over fixed fields and separately mixed-characteristic DVRs.
Applicability and commercial boundary
Finiteness is not effective enumeration, and the base field/ring remains fixed. No small classification database follows without bounds.
Initial business decision
Research reference or conditional symbolic/verification engineering. No practical implementation, recurring buyer need or profitability has been demonstrated; a weak business bridge is explicitly deferred.
Next verification action
Inspect effective representative and bound construction before a software catalog.
Evidence scope
The catalog statement was individually reviewed. Main-paper proof, construction effectiveness and selected formal scope comparison remain queued. No independent Lean verification was run. Source revision fd4aeeb2ee4fc729c18d98444fed42fd0529eeeb. See source metadata.
