Battle.leak emits its own 'leak' event, which no sound handled, so every leak was silent; the client now plays battle.ON_ENEMY_REACHED_EXIT (b_ui_alarmenter) with the bank's own one-at-a-time rule, leaks closer than the sound's length sharing one alarm. The manifest gains only audio.sfx.battle.leak. Contributed by @Convey123.
Deploy, skill and result lines come from the operators' official voice slots; a newer line takes the channel over (stale callbacks of the replaced line no longer release it), and the result line is spoken by an operator of the player's own battle. Contributed by @Convey123.
The 联防 phase plays m_bat_corrosion (intro + loop), the track of the official escaped stages, instead of carrying on with the round's battle music; without the downloaded track it falls back to the battle music. Asset plan, manifest entry (audio.bgm.unite), audio.js and tests. Contributed by @Convey123.
The emote E2E suite accepts either the local-client extraction or the copies tools/fetch-assets.mjs downloads (public/assets/ui/emoticon), and checks the wheel's official cell sprite only when the local ui/battle art is present. Contributed by @Convey123.
