Enum DiscoveryFailurePolicy 

#[non_exhaustive]
pub enum DiscoveryFailurePolicy {
    FailClosed,
    ProceedWithKnown,
}

What to do when RFC-ACDP-0014 §8 auto-discovery itself fails (a transient search/lookup error, or the discovery search functions’ own safety-cap error).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FailClosed

Treat a discovery failure as a verification failure (AcdpError::RevocationDiscoveryFailed). Default — matches this crate’s existing bias (§7’s own lineage-walk and verification-failure paths already fail closed; see crate::revocation’s doc for the parallel reasoning) that an authorization phase which could not run is not the same thing as one that ran and found nothing.

ProceedWithKnown

Proceed using only RevocationPolicy::known when discovery fails, silently dropping whatever discovery could not complete. Use only when availability matters more than catching a revocation that discovery would otherwise have found.
