Enum PredicateProofPolicy 

pub enum PredicateProofPolicy {
    Always,
    OnRequest,
    Never,
}

Proof emission policy for a predicate.

Variants

Always

Always emit proof for queries on this predicate.

OnRequest

Only emit proof when the query asks for it.

Never

Never emit proof (e.g., bulk lookups where proof is contractually elsewhere).
