+# CASAN Plan-16 SEC-23 Phase 1 (MT-01) — tenant-partitioned state store + guard.
+#
+# Proves:
+#   * 23.1 two tenants resolve to DIFFERENT partitioned paths; an invalid/traversal
+#     tenant id or logical name is rejected,
+#   * 23.2 cross-tenant guard: tenant A cannot access tenant B's path (DENY), but its
+#     own path is allowed,
+#   * 23.3 the tenant root is created 0700 (owner-only),
+#   * 23.12 secure-by-default: prod with no CASAN_TENANT_ID fails CLOSED; dev falls
+#     back to a 'default' tenant; prod WITH a tenant is fine.
+#
+# Deterministic; hermetic (temp tenant-state root); no model/network.
