+Tests for policy registry and the learning/improvement loop.
+
+Verifies that:
+  - Trained policies are persisted to CH
+  - Registry manages lifecycle (CANDIDATE → ACTIVE)
+  - Engine loads active policy from registry
+  - Hot-reload via control plane works
+  - Full training → registry → engine flow works
