+/// Exercises compromised and independent test certificates with offline PKIX validation.
+///
+/// `test-chain.pem` contains a locally generated leaf, intermediate, and self-signed root,
+/// in that order, without private keys. The certificates use EC `secp256r1` keys and were
+/// generated with `keytool`, a start date of `2026/01/01 00:00:00`, and a validity of 3650 days.
+/// The leaf permits server and client authentication; both CAs permit certificate signing.
+///
+/// The compromised certificates also match the original Mozilla report attachments:
+/// [original issuances](https://bugzilla.mozilla.org/attachment.cgi?id=9664066) and
+/// [cross-signs](https://bugzilla.mozilla.org/attachment.cgi?id=9664067).
