Enum ReceiptPolicy 

pub enum ReceiptPolicy {
    Ignore,
    VerifyIfPresent,
    Require,
}

How to treat the optional registry_receipt on retrieval (RFC-ACDP-0010).

Variants

Ignore

Skip receipt verification entirely (0.1.0 behavior). The receipt value is still preserved verbatim on the context.

VerifyIfPresent

Verify the receipt when one is present; absence is not an error (the registry may simply be a 0.1.0 registry). Default.

Require

Fail closed unless a receipt is present AND verifies. Use when the deployment requires audit-grade provenance — registry claims (ctx_id, created_at, origin_registry) are assertions, not proofs, without a receipt.

Honored identically by every entry point that accepts a VerificationPolicy — fetch_with_policy, fetch_current_with_policy (via LineageHeadPolicy::receipts), and the fetch_report* family. On VerifiedContext::fetch_report_diagnose the failure surfaces as a withheld handle plus VerificationReport::policy_phase_error, not an Err — see that method’s doc.
