+    10|1. Primary model (Anthropic) down -> switch config to local-llama.cpp

+    12|3. VPS agents down -> alert + lazarus protocol
+    13|4. Local llama.cpp down -> try Ollama, then alert-only mode
+    14|5. All inference dead -> safe mode (cron pauses, alert Alexander)
+    15|
+    16|Each fallback is reversible. Recovery auto-restores the previous config.
