description: "Turns one permissioned-validator event on an Avalanche Evergreen L1 -- a validator add, remove, or weight change -- into change-control evidence in the shape the SOX/ICFR control family already uses: the authorization chain of named identities, the weight delta and its share-of-total effect against a caller-supplied total network stake, and a quorum verdict comparing the caller's declared approval-quorum policy against what the caller states was achieved, plus a structural exceptions list (nonzero prior weight on an add, nonzero posterior weight on a remove, no delta on a weight change, an unauthorized change, an achieved-quorum count exceeding the number of named authorizers). No baked-in quorum threshold: quorum_required is the caller's own policy for that Evergreen L1, exactly as art-445/art-494 refuse to bake in their own thresholds. No chain observation, no P-Chain query, no RPC: the event is transcribed by the caller. Not X: use art-503 for a §27 dual-control certification that counts distinct approvers against a statutory-or-policy threshold across a subject; this node evidences one validator-set change event, not an approval-count certification. compliance_control. Zero PII: validator_ref and every authorizing identity are opaque references."
