NAME: discriminating_ledger

Target: the trickle and decoy-heavy attackers, and the matches they win against identify_then_engage (trickle: 0.155) and nearest_first (decoy_screen: 0.107).

The weakness: both of those defenders spend their resources on decoys.

• nearest_first shoots whatever is closest. In the sample match it killed all 16 decoys and let 3 strikers through.
• identify_then_engage fired all 120 gun rounds against a trickle that was half decoys, and ran dry before the strikers arrived.

This bot keeps a strict ledger of what each threat is:

• Interceptors are only ever sent at confirmed strikers, or at unknown tracks that are already inside id range (these should not normally exist).
• Each striker gets exactly one interceptor. Anything else is only launched when that striker's interceptor is gone and the striker is still alive.
• If an interceptor's target disappears, it is retargeted to the most urgent striker that has no interceptor.
• The gun only fires at strikers. It prefers strikers with no interceptor on the way, then the closest one. Decoys are never engaged, so ammo lasts against a long trickle.
