handleSwitchModel always UUID-parsed modelId and errored on null, so a session could never be reverted to automatic model selection mid-chat. Parse modelId as a string: null/empty/"auto" clears the session model (setModel(null) + save, responding modelName "Auto"); a UUID selects a concrete model; an invalid UUID returns a clean error instead of throwing.
