// Guards the fix in commit 356607c: Kiro's agent/"vibe" mode sends modelId
// "auto" for the main turn and "simple-task" for background sub-tasks. Both
// need a mappable defaultModels slot — otherwise getMappedModel (src/mitm/server.js)
// returns null and the /generateAssistantResponse call is passed through to AWS
// instead of being routed to the user's chosen provider (surfacing as Kiro's
// "monthly usage limit" once the AWS quota is gone).
