// Production hardening II Phase 7 — typed audit-action codes for the
// cert-export surface.
//
// Naming contract: every code is `cert_export_<format>` where
// <format> ∈ {pem, pkcs12} for the success cases and `_failed` for
// the error cases. Operators grep the audit log on these exact strings
// to find every export event for compliance + breach-investigation
// purposes.
//
// Pre-Phase-7 the audit log carried inline strings ("export_pem" /
// "export_pkcs12"). Those bare codes are PRESERVED for back-compat
// with existing audit-log analysers; the new typed constants are
// emitted alongside via the split-emit pattern (mirrors the EST
// hardening bundle's est_audit_actions.go split-emit at
// internal/service/est.go::processEnrollment).
//
// All four codes appear in the troubleshooting matrix in
// docs/security.md::Production-grade security posture per the Phase
// 10 documentation deliverable.
