Our player's create now does its own writes inside the update packet, at the end of its create step (`0x5dec7b`), as 1.12.1's PostInit does:
- SelfPlayer is tagged in the create's own commands, so a later packet in the same frame finds us tagged and in control.
- The control flag and its two signals (`0x5deb56`), gated on `+0xc8` (`0x5deb49`).
- `CMSG_SET_ACTIVE_MOVER`, sent only when the mover changes (`0x6006ee`-`0x6006fb`). The mover clears at world entry, at the unit's destructor, at a release and at a control stop.
- The cascade message (`0x5deb60`), then the class family (`0x5debcc`).
The movement lock moves to its own resource. Only the arrival writes it, so a `/reload` while feared or possessing leaves it alone, since 1.12.1's reload runs only `0x4908c0`.
Each change has a test that fails without it. flip_readiness falls to 96 rows.
