The hostile starts 4000 m ahead with no track of the player; stepped headlessly it
sees the player at tick 81 and paints a Track lock at tick 83. LockOnSituation pins
the staging, the absence of a paint at Update(0), and the lock's bearing and timing.
LockOn.cs.meta is provisional until the Unity compile on Starfire writes its own.
Builds: yes (not yet run; verification follows).
