Why: The dev service is an rdm build, so startup skipped model seeding and kept the old MiniMax chat model. Later starts need the saved env file applied even without an admin key command.
Evidence: seed and rdm launcher tests passed. The live dev database now uses the four-model chat route and keeps the original MiniMax endpoint as reserve.
Impact: Restart of a service with envfile set rewrites system model settings. HTTP seeding is unchanged for builds that can mint an admin key. MiniMax is stored separately because fallbacks cannot switch gateways.
