 - `hermes doctor --fix` migrated root and Uma configs to version `24` on 2026-05-27.
 - Optional providers/search backends are mostly not configured yet. Configure through Hermes setup/auth flows only; never commit credentials.
+- Local Ollama fallback models are installed on demand, not kept hot permanently. Both Hermes instances can reach the shared host service at `http://127.0.0.1:11434/v1`. `gemma4` was attempted but the installed Ollama runtime rejected it, so the vision fallback is `llama3.2-vision`.
