PROPOSAL INTENT: ---BEGIN INTENT--- {intent_text} ---END INTENT--- CANONICAL ACTIONS: ---BEGIN ACTIONS--- {canonical_actions} ---END ACTIONS--- Classify five independent dimensions: - recipient_alignment: do all recipients/spenders match the proposal intent? - asset_alignment: do all native/ERC-20 assets match the proposal intent? - amount_alignment: are all amounts and limits within the proposal intent? - scope_alignment: are all actions within the declared purpose with no undeclared extra action? - permission_alignment: are approvals explicitly permitted, bounded, and consistent with the proposal? Use MATCH only when the intent clearly supports every action for that dimension. Use MISMATCH when at least one action contradicts or exceeds the intent.
