      "prompt": "I'm building a companion app for Bluetooth headphones. I need a picker that discovers our BLE service, asks for permission, and later talks to the device firmware. Should I use AudioAccessoryKit for all of that?",
      "expected_output": "A boundary-aware answer that routes discovery and permission setup to AccessorySetupKit, BLE transport to CoreBluetooth as needed, and AudioAccessoryKit only to post-pairing audio-switching configuration.",
      "files": [],
      "expectations": [
        "The answer recommends AccessorySetupKit for discovery, picker UI, and pairing or authorization.",
        "The answer mentions CoreBluetooth only for accessory transport or firmware communication after permission as appropriate.",
        "The answer limits AudioAccessoryKit to post-pairing audio accessory registration, placement, and connected source updates.",
        "The answer does not present AudioAccessoryKit as the framework for BLE discovery or picker UI.",
        "The answer preserves the sequence: pair first, then register audio configuration."
