Wider same-seed sampling of the finite-burn/coast change: baseline 2689d93
(pre-#120) against the current tree, 6 variants x 8 seeds of a 46-drone raid
(batt10/20/50, near200, far1500, hills20). Harness-only: Result carries the
tally's fuse/expired/orphaned/energy_lost counts and a new ignored
sim::balance::issue_120_grid test; no simulation parameters changed.
Findings: kills are equal or up and leaks equal or down in every variant;
fuse misses drop (far1500 70 -> 38 over 8 seeds); hills terrain losses fall
(scrubbed 6 -> 2). MotorEnergyLost never fires in the 48 scenarios and
expired stays <= 1: coast ends before drag reaches the 25% guidance
threshold. Leaks stay concentrated in the ballistic/fast classes
(Iskander/Kinzhal/Kh22/Zircon). No confirmed defect, so no tuning.
Full airdef-core suite: 193 + 8 passed, 0 failed (baseline side 169 + 4).
