      "area": "Switch mechanism",
      "owner": "Jacob / Elian",
      "detail": "Measure actual four LIDUOLE bodies, terminals after wiring, actuator/free/operating heights, travel and force. Fit and electrically test adjusted stacks, center/edge press and return with shell closed. Nominal sizes and analogous click travel are estimates."

      "area": "PCB and U6",
      "owner": "Elian",
      "detail": "Use fb5acde7 PCB. Supplied STEP omits U6; nominal 24 x 24 x 2.4 mm placeholder is preliminary. Obtain corrected populated STEP or measure actual assembly, including solder standoff, connectors and shield clearance."

      "area": "Antenna and RF",
      "owner": "Elian / RPS",
      "detail": "Use Taoglas FXUB63.07.0150C and cable. Check fit, routing, metal clearance and cellular performance in complete case. Preserve exterior; investigate layout before resizing. GNSS antenna/cable omitted; PCB capability retained."

    {
      "area": "Battery and wiring",
      "owner": "Elian",
      "detail": "Verify actual battery maximum thickness, padding/compression allowance, safe wire routing and connector/USB mate envelopes. Harness and J9 control assignment remain to be approved; do not use CAD lead models as pinouts."

    {
      "area": "Appearance approval",
      "owner": "Jacob / RPS",
      "detail": "Match physical colour/texture coupons; proposed Pantones are starting targets, not measured matches. Select hardness, brush/grain direction and metal surface quality before a cosmetic batch."
