+# CASAN Plan-17 Track 5 — Meta-loop (self-improving loop policy).
+#
+# Proves:
+#   * propose is dry-run (emits proposals, writes nothing to the CP store),
+#   * apply enforces Separation of Duties (proposer == approver -> DENY),
+#   * apply requires an approval (no approval -> DENY),
+#   * a loosen proposal above the org hard cap is refused (17.19),
+#   * an approved loosen is applied via the governed store AND actually changes the
+#     governor's effective ceiling (governed override is real, not paper),
+#   * rollback via the governed store reverts the governor's behaviour,
+#   * the CP audit chain stays intact,
+#   * no repo / home pollution (sandboxed state, store, keys).
+#
+# Deterministic; hermetic; dev profile keeps the backward-compatible approval gate.
