-Layer 1 (GRPO)      → Optimizes system prompts
-    ↓
-Layer 2 (OpenEnv)   → Conversation environment

+    ├── Prompt A → tested on 3 customers → mean reward A
+    └── Prompt B → tested on 3 customers → mean reward B

+    GRPO update: reinforce the better prompt

-Swap domain (banking → telecom) → new environment automatically.
+**Total training cost (default config):** 5 steps × 2 candidates × 3 customers = 30 conversations
