// test/feedback7-chen3-s3-sfx.test.js — user report 「赤刃明霄陈开启三技能后斩击音效应该和普通攻击不一样」 (2026-10-08).
//
// 赤刃明霄陈 (char_1050_chen3) has both kinds of bank, and BOTH of her S3's sounds differ from her normal attack —
// excel/audio_data.json, her ability banks (`attack.<n>` = the mode; the mode is in the file name):
//
//   battle.ON_ABILITY_START.char_1050_chen3.attack.0    → p_atk_hljdswd_n   普通攻击（默认形态）
//   battle.ON_ABILITY_HIT.char_1050_chen3.attack.0      → p_imp_hljdswd_n   普通攻击的命中
//   battle.ON_ABILITY_START.char_1050_chen3.attack.1    → p_atk_hljdfswd_d   技能1
//   battle.ON_ABILITY_HIT.char_1050_chen3.attack.1.0    → p_imp_hljdrfswd_d  技能1 的命中
//   battle.ON_ABILITY_HIT.char_1050_chen3.attack.1.1    → p_imp_hljdylfswd_d  技能1 的命中（第二个变体）
//   battle.ON_ABILITY_START.char_1050_chen3.attack.3    → p_atk_hljdswd_s    技能3
//   battle.ON_ABILITY_HIT.char_1050_chen3.attack.3      → p_imp_hljdswd_s    技能3 的命中 ← 这就是「斩击」
//
// `pickUnitSfx` refuses skill-mode files for the NORMAL attack / impact (社区反馈 #54, 银灰) and therefore keeps the `_n`
// pair — correct. The fix of 司霆惊蛰 (test/feedback6-…) already plays the mode's own swing while the skill runs; this
// report is the other half: without a per-mode IMPACT the S3 slash still landed with p_imp_hljdswd_n, i.e. it sounded
// like her normal attack. tools/assets/audio.mjs pickModeHits() now reads `ON_ABILITY_HIT` per mode (same mode letters,
// same slot rule), plan.mjs writes it as sfx.units[id].hits = { '<skillIndex>': url }, and public/js/audio.js plays it for
// an attack that was aimed while that skill ran (the attacker's state travels with its impact bookkeeping).
//
// Run: node --test test/feedback7-chen3-s3-sfx.test.js
