+extraction_notes: "Pure formal verification paper with no direct AI alignment discussion. Enriches existing Arrow's impossibility claim by providing machine-checkable proof foundation. No new claims warranted—this is methodological advancement (formal verification) rather than novel theoretical insight. The timing (Feb 2026) is notable as formal proof tradition catches up to applied alignment work, but the paper itself contains no KB-relevant arguable propositions beyond strengthening the mathematical rigor of existing claims."

 ## Key Facts
-- Arrow's impossibility theorem received a full formal representation using proof calculus (Yamamoto, PLOS One, February 2026)
-- The formal proof complements existing computer-aided proofs from AAAI 2008 and simplified proofs via Condorcet's paradox
-- The derivation reveals the global structure of the social welfare function central to the theorem
