 - OpenAI model lists are filtered to models that are expected to work with the backend's Responses API implementation.
 - `hermes-agent` is included only when `HERMES_AGENT_API_KEY` is configured. Set it to Hermes `API_SERVER_KEY`, or any non-empty value if that local server does not require auth. `HERMES_AGENT_API_BASE_URL` defaults to `http://127.0.0.1:8642/v1`; set `HERMES_AGENT_MODEL` only when you need an additional fallback/override model id.
- The backend loads provider model lists at startup and refreshes them about once every 24 hours. If a later provider refresh fails, the response keeps the last loaded model list for that provider and sets `error` to the latest failure message.

- This endpoint is intended for combined conversation/search lists such as sidebars.
- The legacy `GET /v1/chats` and `GET /v1/searches` endpoints remain available for clients that need separate collections.
- The response currently combines up to 100 chats and up to 100 searches.
- `starred`/`starredAt` are backed by membership in a reserved `Project` with id `starred`; future project folders can reuse the same project item model.
