+# CASAN Plan-16 SEC-23 Phase 2 (MT-01) — per-tenant governance state isolation.
+#
+# The control-plane settings store (settings + its embedded audit hash-chain) and
+# telemetry are now partitioned per tenant. Proves:
+#   * 23.5 a setting written by tenant A lands under A's partition; tenant B does
+#     NOT see it (separate store),
+#   * 23.4 the store (incl. its audit chain) is a distinct on-disk file per tenant,
+#   * cross-tenant guard denies B access to A's store path,
+#   * an invalid tenant id fails CLOSED in the control-plane tool,
+#   * 23.6 tenant-paths.sh resolves telemetry + CP paths under the tenant partition,
+#     and an explicit override still wins.
+#
+# Deterministic; hermetic (temp tenant-state root); no model/network.
