shadow_pair_ring

Idea: Every striker is parked directly behind its own decoy on the same radial line, so the pair stays nose-to-tail and a range-only gun always shoots the decoy in front.

Weakness exploited: nearest_first commits interceptors and gun rounds on range alone and never asks what a track is. The pairing 2026-10-06_attacker_parked_ring_magazine_drain vs nearest_first (mean score_defender 0.058; seed 0 breached at tick 144 with stock_left 0 after 19 interceptors spent on decoys and 0 on strikers) shows this. The defender emptied its whole 20-round magazine on 0.5-credit decoys, then 20 strikers walked in.

Plan:

1. Drain: 30 decoys fly straight in on spread bearings. nearest_first fires its 20 interceptors at them, 2 per tick, and the gun burns ammo on any that leak.
2. Shadow park: 18 strikers hold at r=472, just outside the 450 radar. Each has a decoy "shield" held at r=462 on the exact same bearing.
3. Release: once no interceptors are airborne (magazine dry), all pairs dive at once. Each decoy stays 10 units ahead of its striker. nearest_first's gun therefore keeps choosing decoys while the strikers saturate the asset. Three hits are enough.

Budget: 30*0.5 + 18*2 + 18*0.5 = 60.
