How to read this layout

  • LE means least-significant byte first.
  • fixed16 is two-byte sign-magnitude at 1/64 precision.
  • orientation16 uses the measured 1/8192 orientation mapping.
  • NUL strings consume their encoded byte length plus one 00 terminator.
  • Counted arrays repeat immediately in the order shown.
