Three bugs caused the radar to sweep continuously instead of locking: 1. run() loop set radar to Inf every tick, overwriting any lock → replaced with enemy_tracker.getRadarTurnRate() 2. onScannedBot used radarBearingTo() (math convention, east=0 CCW) → removed; run loop now handles radar via enemy_tracker 3. enemy_tracker.getRadarTurnRate() had arctan2(dx,dy) instead of arctan2(dy,dx) — introduced by fd22535; bearing was off by ~90° Also relaxed stale-lock threshold from 2 to 8 ticks to survive brief scan gaps without falling back to full sweep. Added tools/battle_runner for automated 1v1 testing. Result: 1303/1308 ticks with successful scan (was ~1 in 4).
