Target: 2026-09-28_defender_discriminating_ledger.

Which part of its logic this attacks ------------------------------------

1. The id gate in is_threat(). The ledger only engages confirmed strikers, or unknown tracks closer than 0.9 * id_range (135). Anything parked at about 190 is ignored. It gets no interceptors and no gun, so we can loiter there for free and choose when every striker starts its run.
2. The magazine plus the launch rate. It only has 20 interceptors against our 30 strikers, and a cap of 2 launches per tick. The ledger gives one interceptor per striker, so the stock is gone after the first 20 strikers are engaged.
3. The single gun. After the stock is gone the gun is the only thing left, and it can pick one track per tick with a low per-shot kill chance.

What the replays show ---------------------

• Against rush (seed 0), 30 strikers came in on a tight axis. The ledger killed all 30 with only 20 interceptors, so the 10 m blasts took several strikers each. Clustering helps it. We spread 30 strikers evenly around the ring (12 degrees apart, about 20+ units apart where the interceptors meet them), so one blast should kill one striker.
• Its closest calls were all multi_axis (asset hp 10). Stock hit 0 and strikers leaked at ticks 165 and 166, arriving at nearly the same time from different axes. When arrivals overlap in time and the stock is empty, the one-target gun cannot keep up. multi_axis did that partly by accident and wasted budget on decoys. We do it on purpose, with all strikers and no decoys.

Plan ----

• Calibrate the bearing convention with one launch, then launch the rest on evenly spaced bearings.
• Hold every striker on a ring at radius 190, outside the gate, until all are on station.
• Release all strikers on the same tick. About 30 strikers enter id range together. At most 20 interceptors (about 17 kills at 0.85) can be used, and the roughly 10 survivors arrive within a few ticks of each other. The gun gets about 19 shots with a weak kill chance, and 3 hits destroy the asset.
