+#    existing value in the environment wins), mirroring hass-cli-wrapped
+#  - GitHub Copilot: extra-openai-models.yaml routes copilot-* models through
+#    the local copilot-api proxy (modules/copilot-api.nix, port 4141)
+#  - Ollama: llm-ollama plugin baked in; talks to a server on localhost:11434
+#
+# llm reads extra-openai-models.yaml from LLM_USER_PATH, but that directory
+# must stay writable (llm keeps logs.db there), so it can't point at the
+# store. The wrapper points it at a state directory and refreshes the
+# store-sourced config there on every launch, keeping the file declarative.
