Case Fit Desk: an eurorack case-fit agent that refuses to invent HP, depth, or milliamps

{
  "output": "Current topic: \"Verifying Live Deployment via End-to-End Curl Tests\"\nTopic summary: I am starting an investigation to verify the live production deployment at https://case-fit-desk.vercel.app. I will inspect the API routes in apps/web to understand their exact request schemas, use curl to execute real end-to-end HTTP requests against /api/fit and /api/chat, and summarize the results clearly.\n\nStrategic Intent: Verifying live Case Fit Desk deployment via endpoints /api/fit and /api/chat using curl."
