The 伤判效果 that act after a barrier need it: 煌's 紧急除颤 lock (buff template huang_t_1[lock], an ON_TAKE_DAMAGE HpNoLessThanCertainPercentModifier; PRTS 备注 "该伤害减少(伤害值-煌当前生命值+煌最大生命值×50%)点") and 左乐's SBL-X 庇护 re-applied behind his 行险 barrier (PRTS S2 备注). Additive: without a handler the pipeline is unchanged, so golden is unchanged (every family matches). docs/SIM.md §4 / §5 name the hook; test/sim/feedback5-hpdamage-hook.test.js (2).
