- Stock: fixed trait gifts (缪尔赛思 / 变形者集群 变形同构体, 耶拉 不融冰, 蜜蜡 / 卡涅利安 迅捷作战粮, 诗怀雅 盟约之币) still occupy stock but are granted past the cap; an operator card already shown in the shop or a reward can be taken after the pool runs out and overdraws (GitHub #498, the owner's decision); item buys and item rewards keep the stock check. 洛洛 / 焰尾 sub-pools use the measured weights (PR #497 by @2321Robin; the occupancy idea of PR #496 by @2321Robin re-implemented differently). - Boss pairs are drawn at random once per match and fixed to battle start; the Hidden Core reuses them; a leaver does not split a full pair (the owner's decision). - 阿戈尔 in 联防 no longer re-applies the opening devour HP loss or a false revive; Touch's team medic stays for the match after its holder leaves (owner-approved, official lifetime unverified). - Auto-skill ranges: 司霆惊蛰 S2, 斩业星熊 S3 against air, 予愿安洁莉娜 S3; 自在's post-rebirth invulnerability is also untargetable (#510); Horn / Clementia / catapult / 忍冬 first hit (PR #502 by @Xinglan233); 不融冰 / tear gas trigger on real damage. - Bond layer-up sound in round start / draft / prep / battle (#482): one channel, a new cue replaces the old, no extra cooldown; a prep update that adds layers and activates a bond plays one cue. - Client: multi-swing fix (#506), refresh single-flight (PR #507 by @robll-v1), LP tower keeps the settled value with a −N tick (PR #504 by @robll-v1), export with only 潜能 / 练度 changes (PR #503 by @Xinglan233), spectator rosters list DIY members (PR #505 by @Xinglan233), banned members beside bond tooltips (PR #494 by @YuriRestia), recovery action above the away overlay (PR #511 by @RainoutOvO), the /dev/sim-check.html consistency page (PR #492 by @Cloudnyco), Korean (PR #490 by @D-Roote) and English Victoria wording (PR #499 by @YuriRestia). - golden: 45 of 287 scenarios move against 0.2.4 (roster 17, bonds 3, fields 6, matches 17, standins 2), each attributed in docs/history/0.2.5.md §30.9 / §30.16.

// Audio manager (Web Audio): BGM per phase, UI SFX, per-unit battle SFX, operator battle voice. Never throws.
|
||
//
|
||
// Sources: data/assets.json → audio (docs/ASSETS.md):
|
||
// bgm { lobby, prep, combat, combatAlts?: [ {intro?, loop}, … ], boss: { intro?, loop } },
|
||
// bossBgm { [bossId]: { intro?, loop } },
|
||
// voice { [charId]: { start, faceEnemy, select, place, skill1…skill4, squad, squadFirst, result*, gacha } },
|
||
// voiceJp { [charId]: { …the same slots } } (the Japanese dub, settings 语音语言 日本語; see voiceLine),
|
||
// sfx.ui { click, buy, sell, refresh, freeze, levelup, merge, equip, ready, timer, yourTurn, … },
|
||
// sfx.battle { deploy, tokenDeploy, charDie, tokenDie?, enemyDie, enemyHit, heal, killCoin, … },
|
||
// sfx.units { [charId|tokenId|enemyId]: { attack?, hit?, skill?, die?, born?, mix?: { [role]: { p?, vol? } } } }.
|
||
//
|
||
// - The AudioContext is created on the first user gesture (pointerdown/keydown/touchend), so browsers
|
||
// never block or warn; everything requested before that is remembered (BGM) or dropped (SFX).
|
||
// - Channels: master → { bgm, sfx, voice } gains; volumes from settings (0..1) + mute. Tab hidden ⇒ suspend.
|
||
// - BGM: `intro` then `loop` (1 s crossfade); switching tracks fades out/in (0.8 s). The same loop URL
|
||
// keeps playing across phases (prep and combat share a track).
|
||
// - 开战 BGM: `bgm.combatAlts` are the mode's own battle tracks (塞壬唱片 骑士之日 / 无畏者). The track is fixed per
|
||
// round, not drawn: 无畏者 through rounds 1–7 and 骑士之日 from round 8 on (`combatTrackFor`, the official
|
||
// schedule), so every client of a match hears the same one, a fight never switches track halfway through and the
|
||
// 联防 that follows a 作战 keeps its round's track.
|
||
// - 干员战斗语音 (`audio.voice`, user request): an operator says the official line of the moment it is in —
|
||
// 行动出发 start, 行动开始 faceEnemy, 部署 place, 作战中1-4 skillN and the settlement's 结算 result* (battle-only),
|
||
// and 选中干员 select whenever the player taps an operator — in the prep, the shop and the hand too (the owner's
|
||
// request of 2026-10-08 「添加一下干员点击上去的语气一样的语音」, which lifts 2026-10-03's 「整备阶段不需要干员语音」 for
|
||
// this line only). Voices are seconds long and a battle deploys eight
|
||
// operators, then fires dozens of skills, so they run on their own channel (own gain, settings 干员语音) through
|
||
// VoiceGate: one line at a time, a global gap, a per-unit per-slot cooldown, and a higher-priority line taking the
|
||
// channel over — the official scheduling of `audio_data.json battleVoice.voiceTypeOptions` (a tap's 选中 line skips
|
||
// the gap: VOICE_TAP_SLOTS). Two dubs: 中文 `audio.voice` (default) and 日本語 `audio.voiceJp` (settings 语音语言, not
|
||
// tied to the interface language; the owner's request of 2026-10-08 「全套的日配语音」) — a JP line the manifest or the
|
||
// host lacks falls back to the Chinese one (voiceLine).
|
||
// - Battle SFX from `b.ev` tuples (`handleBattleEvents`): at most MAX_VOICES concurrent unit sounds, at most
|
||
// MAX_PER_URL overlapping copies of one sound (the official banks' maxSoundAllowed 2), a per-unit cooldown and a
|
||
// per-URL minimum gap (SfxLimiter), so a 60-unit fight stays listenable. A `['skill', id, 1]` that arrives before its
|
||
// unit is known is held and played once the unit is tracked (`pendingSkill`): a unit that casts inside its own deploy
|
||
// tick emits that first cue before its `['spawn', unitInfo]`, and dropping it left the one cast silent while every
|
||
// later one played (GitHub PR #292 by @LimitlessHPPK).
|
||
// - Impact sounds (user playtest #4 item 6): a 'dmg' plays the `hit` sound of the unit whose hostile attack ('atk' on a
|
||
// unit of the other side) aimed at the target — once, within IMPACT_WINDOW_MS, and only for phys / arts / true damage.
|
||
// A heal "attack" ('atk' of a healer on an ally, chain heals) never makes the healer the author of the next damage
|
||
// on that ally (纯烬艾雅法拉's heals made every later hit on a healed ally ring her impact sound), element gauge fills
|
||
// and DoTs play none, and a chain bounce ('chain' / 'chainHeal': its first id is the previous target) plays no attack
|
||
// sound of that target. An operator's attack / hit sound that is a skill-mode file of its own (official names end in
|
||
// `_n` for the normal attack, `_d` / `_h` / `_s` for its skill modes — the manifest picked 纯烬艾雅法拉's S3 impact
|
||
// p_imp_gtshpbrnch_s as her `hit`) never plays for a normal attack (normalAttackSfx).
|
||
// - The attack sound of the RUNNING skill (`attacks`, 技能1 / 2 / 3 = `_d` / `_h` / `_s`): an operator whose every attack
|
||
// belongs to a skill mode has no normal attack bank at all — 司霆惊蛰 (解放者: she only attacks while a skill runs) was
|
||
// completely silent when she attacked (report 「三技能攻击没有音效」). The manifest then carries that mode's own file
|
||
// per skill index (`attacks`, tools/assets/audio.mjs pickModeAttacks) and it plays while the skill is active, from the
|
||
// `['skill', id, 1]` / `0` events; a unit with a normal bank too (能天使 S2 过载模式, 史尔特尔 S2) keeps that bank
|
||
// outside the skill. Being the official file of that very skill, it is not the normalAttackSfx case above.
|
||
// - …and its impact (`hits`): a mode's swing is not always the whole difference — 赤刃明霄陈 S3's slashes swing
|
||
// p_atk_hljdswd_s AND land p_imp_hljdswd_s, while her normal attack uses p_atk_hljdswd_n / p_imp_hljdswd_n
|
||
// (report 「开启三技能后斩击音效应该和普通攻击不一样」). Same mechanism and the same window: the `hit` of an attack
|
||
// aimed while the skill ran — the attacker's state travels with `lastAttacker`.
|
||
// - The official bank mix of a unit's own attack / hit / die / born sound (`mix`, tools/assets/audio.mjs bankMix; community
|
||
// report #30): it plays with chance `p` — 猎狗pro / 深池侦察犬's attack bank is 80 % silence, so they bark on about one
|
||
// attack in five (never replaced by the generic enemy sound) — at its base gain × `vol`, capped at 1: an official volume
|
||
// below 1 is quieter (妖怪's 0.7), none is louder than before (unitGain).
|
||
// - Deaths/deployments follow the official per-class defaults (unitSoundClass): only operators play the
|
||
// operator-knocked-down sound; summons use the token sounds; a summon used up by its own effect (fx `consumed`,
|
||
// 香槟炸弹) plays its impact sound instead of a death sound.
|
||
// - Buffers are fetched once and cached (LRU); failed fetch/decode ⇒ silent (logged once as a warning).
|
||
//
|
||
// `bgmKeyFor(route, pub)` picks the track for the current screen/phase (main.js calls `audio.install()`,
|
||
// which follows the store).
