Exact field order

Packet 37 wire layout

The first byte is the application packet ID. The rows after it appear in decode order. Sizes exclude ENet headers, the outer wrapper prefix, LZF chunk framing, and compression effects.

Protocol convention

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.
