    "Microphone and LED openings are placeholders, not verified acoustic paths or light pipes.",
    "Antenna is in a separate rear upper pocket, not over the battery; body detuning still requires RF tests.",
    "Battery is nominal; finished pouch, protection PCB and wire dimensions require measurement.",
    "Power wires use provisional 0.6 mm OD; coax uses provisional 0.7 mm OD. Endpoints mark terminal regions, not verified pad locations.",

    "No final mechanical travel stops, pinch protection, cowl retention, or strain-relief clamp selection.",
    "No installed switch selection; never wear or charge an unvalidated prototype."
