+# CASAN Plan-14 — RBAC decision audit into an H5-style oversight log.
+#
+# Every RBAC allow/deny decision is recorded (opt-in via CASAN_RBAC_AUDIT_LOG) so a
+# reviewer / RAI report / Control Plane can see who was allowed or denied what and
+# why. Proves:
+#   * an ALLOW decision is logged with verdict + role + action,
+#   * a DENY decision is appended (append-only) with its reason,
+#   * a cross-tenant DENY records the tenant-boundary reason,
+#   * with no audit-log env set, nothing is written (backward compatible).
+#
+# Deterministic; hermetic; no model/network.
