feedback5 CB3: 银灰's normal attack no longer plays his S3 swing (and S2 / S3 impact); 雷蛇, 初雪 and 圣约送葬人 lose a skill mode's impact the same way (community report of 2026-10-06, item 54)

Official (excel/audio_data.json, local client charpack char_172_svrash): his normal attack is the Default mode's Combat —
ON_ABILITY_HIT.char_172_svrash.combat p_imp_spear_n, no swing bank; .attack.2 (p_atk_silver_n swing, p_imp_sword_n impact) is
his S3 mode, .attack.1 his S2 mode. Cause: tools/assets/audio.mjs pickUnitSfx took the numbered variants because their files
end in _n (its skill-mode test is by file name). Now an operator whose default mode is the unsuffixed ability (a plain
attack / combat bank of any event) never takes a numbered variant; operators that number their default mode (attack.0 …)
keep the earlier order. Over the 209 operators of the manifest it changes 4: 银灰 (charpack modes Default / S2 / S3), 雷蛇
(attack.1 = S2, lightning impact), 初雪 (attack.1 = her S1-2 mode) and 圣约送葬人 (attack.4 = S3_End).

data/assets.json regenerated offline (fetch-assets --offline --add-only --allow-shrink; JSON compare: exactly the 4 operators'
entries, hash and stats): 雷蛇 / 初雪 / 圣约送葬人 drop their wrong `hit`; 银灰's entry goes too, because his official impact
p_imp_spear_n.mp3 was never downloaded on this machine — one online `node tools/fetch-assets.mjs --add-only` adds it (needs
the owner's OK for that download). Golden: unchanged (the manifest is client-side). Tests: test/feedback5-operator-sfx.test.js
(3; 2 fail on the parent). Docs: docs/ASSETS.md.
