feedback5 CB2: the countdown summons (医疗探机, 诅咒娃娃, 海嗣; 自选 工程蓄水炮, 沙地兽, 打字机, 本能的召唤) take no damage — 活性源石 included —, are never healed, and their bar shows the life left (community report of 2026-10-06 「赫默的无人机、浊心斯卡蒂的海嗣等这种召唤物不会受到外来伤害…血量随时间减少」)

Official: PRTS 斯卡蒂的海嗣 备注 「持有禁疗、无敌」, the token prefabs of 海嗣 and 沙地兽 carry abnormal flags 5 + 7 (无敌,
禁疗), 工程蓄水炮 7 (禁疗); the report describes the official mode for the drone too — [ASSUMED] 无敌 + 禁疗 for the summons
the base prefabs give no flag (医疗探机, 诅咒娃娃, 打字机, 本能的召唤), and the bar as a timer.
Cause: content/tokens.js / the kits only made them untargetable: a 海嗣 on 活性源石 lost 70 of its 100 HP every second, a
hurt drone drew every medic's heals, and the bar was plain HP. Now: COUNTDOWN_SUMMONS / startCountdown (called where each
lifetime is scheduled: tokens.js scheduleLifetime, 浊心斯卡蒂, 温蒂, 莱伊, 鸿雪, 酒神 kits) give 无敌 + 禁疗 and
Unit.countdown; snapshot.js sends hp = maxHp × the share of the life left (the sim HP stays full, so no selector sees a
low-HP summon). Attacked summons (沙之碑, 狼群 …) are unchanged. The 吟游者 trait therefore cannot refill such a bar (item 32).

Golden: snapshot hashes only (the bar) — roster-003, -016, -018, -035, -045, -046, bond-visiShip-low / -high,
boss-boss_1 / 3 / 5 / 7-pair, unite-1; gameplay too — roster-005 (medics no longer heal the drone), roster-037 and
hidden-boss_9-pair (a 海嗣 / drone under enemy and leader damage stays up: fights change).
Tests: test/sim/feedback5-countdown-summons.test.js (7; fails on the parent: no COUNTDOWN_SUMMONS — and there the 海嗣
lost 70 HP to an 活性源石 tick). Docs: SIM.md token pieces, PLAYING.md 作战中.
