Packet 66 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.
| # | Field | Encoding | Bytes | Purpose |
|---|---|---|---|---|
| 0 | packet_id | u8 | 1 | Always 66 (0x42). |
| 1 | rank_up_count | i32 LE | 4 | rank up count value. |
| 2 | rank_ups[].score_reason | i32 LE | 4 | rank ups[].score reason value. |
| 3 | rank_ups[].old_score | NUL-terminated UTF-8 string | N + 1 | Old score encoded as decimal text. |
| 4 | rank_ups[].new_score | NUL-terminated UTF-8 string | N + 1 | New score encoded as decimal text. |

How to read this layout
LEmeans least-significant byte first.fixed16is two-byte sign-magnitude at 1/64 precision.orientation16uses the measured 1/8192 orientation mapping.- NUL strings consume their encoded byte length plus one
00terminator. - Counted arrays repeat immediately in the order shown.
