Function offlineResponse

website/api/v1/query.ts:36–69

* Builds a tool-specific graceful offline response (HTTP 200). * * CRITICAL: ChatGPT converts ANY non-2xx status into a ClientResponseError. * We must ALWAYS return 200 — even when the browser tunnel is unreachable. * The offline payload gives ChatGPT enough context to tell the user what to do.
