The launch returns a window id when one is available.\n\n**Details**\n\n- The request to record a teach-mode demonstration now has an explicit declined result, which tells the model not to ask again in this session.\n- A separate refusal, cu_lock_held, is returned when another Claude session took the computer while the approval prompt was still open.\n- Screenshot coordinate conversion now reports which coordinate frame a point is in whenever that frame differs from the scaled image.\n- Background launching needs a host that supplies app-scoped control and an app lock already held; otherwise the front-of-screen behaviour applies.\n\n**Evidence**\n\n`In background app mode, the launch does NOT bring it to the front`\n\n- Area: Computer Use\n- Names: `open_app`\n- Tier: Use it now\n- Useful: 3\/5\n- Signal: 3\/5"}
