@@ -27,6 +27,9 @@ both containers. The tracked, sanitized configuration baseline is
 - The configured `dankserver-small` provider reaches `http://192.168.0.235:7770/v1`
   and exposes the `frank-default-small` alias. It is a named provider, so it can
   coexist with the existing `custom` provider for the large model.
+- Both local aliases have `agent.reasoning_overrides` set to `medium`. The
+  llama.cpp endpoints reject unsupported values such as `high` and `none`; the
+  active large endpoint advertises only `low`, `medium`, and `xhigh`.
 - The live `config.yaml` contains secrets and user state and is not committed;
   the tracked example is the sanitized backup of its non-secret settings.
