//! PeerCert source — Hot tier (B4).
//!
//! Peer certificate evidence — TLS issuer organization, subject
//! organization, SAN. `O=Akamai Technologies` is the canonical
//! example of an org field that pins CDN identity.
//!
//! TargetContext today does not carry a peer-cert slot directly; the
//! source is wired so the moment B8 adds `peer_cert: Option<&PeerCert>`
//! the matchers fire. For B4 this source emits nothing in production
//! — its tests use a synthetic context expansion guard.
