// CSAF 2.0 conformance gate for documents emitted by scripts/gen-advisory.
//
// JSON-schema validity is necessary but NOT sufficient for CSAF: the standard
// defines a battery of *mandatory tests* (section 6.1.*) -- CVSS/vector
// consistency, contradicting product status, product_id defined/used,
// tracking.version vs revision_history, and so on -- that a bare schema pass
// happily accepts.  This runner uses the Secvisogram reference implementation
// (@secvisogram/csaf-validator-lib) which bundles every schema (incl. the
// first.org CVSS schemas) and implements those mandatory tests, so the check
// is fully offline and reproducible once the pinned dependency is installed.
//
// Gate = the strict CSAF 2.0 schema test + all mandatory tests.  Optional and
// informative tests are reported as warnings only (they encode house-style
// preferences, not conformance).
//
// Usage:  node scripts/csaf_validate.mjs <doc.csaf.json> [<doc2.csaf.json> ...]
// Exit 0 if every document passes the gate, 1 otherwise.
