//! Public and recipient verifiers over Cardano transaction metadata.
//!
//! The verifier validates a Label 309 record drawn from a Cardano transaction's
//! metadata without trusting the publisher, the operator, or any issuer server.
//! A record must verify only from the transaction bytes, an optional copy of the
//! content, and a public blockchain explorer.
//!
//! This module hosts the security-critical outbound-HTTP layer that the verify
//! pipeline relies on:
//!
//! - [`fetch`] — the canonical outbound fetcher. It enforces a protocol and
//!   method allowlist, a deny-host short circuit for service-independence, a
//!   bounded response-body cap, bounded timeouts, optional retry with jittered
//!   backoff, and a per-call audit trail. It also carries the IP-layer SSRF
//!   guard used for user-supplied (`webhook`) URLs: DNS resolution against an
//!   injectable resolver, a full private/special-purpose IP-range blocklist, and
//!   a resolved-IP return so the caller can pin the TCP connection against
//!   DNS-rebinding.
