// summon of the enemy camp our attacks select — PRTS 铁钳号·原型机 备注 "该召唤物阵营为敌方") counts like an enemy for a
// non-heal skill's automatic start: the owner's rule of 2026-10-08 (community report: 圣约送葬人 hitting the device spent no
// bullet and gained no layer — her MANUAL ammo skill never opened, since every start condition counted enemies only).
// It stays out of enemiesInKeys / canTargetEnemy; a heal skill never counts it (禁疗); 白铁™多功能平台 is not one.
