   * - ⚪
     - Representative or simplified magnetometer layout/defaults.
   * - 🔵
     - Hardware identity and measurement layout are traceable; error defaults may be representative or assumed.
   * - 🟣
     - Blue-tier information plus source-backed measurement noise or accuracy defaults.
   * - 🟡
     - Purple-tier information plus source-backed bias, bias-bound, or calibration defaults.
