feat(new8/batch3-4): cipher/teahouse/keeper/bridge 全套交付——new8 八款全部可交付收官
四泳道并行全流水线（资产→开发→测试→玩家迭代闭环），双双 R1-R2 连续达标裁定可交付： - cipher《暗码》223 断言：摩尔斯解码嵌叙事/四结局矩阵/暴露度逐NIGHT验算/三层兜底；R2 三修（链首标记音/预警震/结局计数句+4句补录）4/4 全满分档 - teahouse《深夜茶馆》205 断言：泡茶时机窗/经济逐晚对账/多晚弧线；连续 2 轮 4/4 愿意玩 P0=0 - keeper《守塔人》257 断言：时空签名教学-兑现/插叙触发回返/trust×truth 档位/4结局；R2 F1/F2 坐实（震型豁免/首播跳句锁）4/4 - bridge《星环舰长》336 断言：巡检节奏逐毫秒/危机×系统态矩阵/仲裁7场景/忠诚差分/评级验算；R1 当场修F1-F4、R2 F5 菜单顺延保护 4/4 上行 公共：index.html 四卡片+profiles.js 四桶+check_all_assets 登记（预接线）、00-program 八款进度账收账、 gen_voice_dual 四游戏段、README/HANDOVER 阵容更新（11 款）、voice_text.json 四游戏键、mureka 台账（累计$1.26/$2.00） 验证：四游戏 playtest 223/205/257/336 全绿 + guide 122/122 + 全项目 15 游戏资产终检绿 遗留：keeper 三代人声滤波人耳试听（最高优先，ASR 对滤波句失明）、bridge 音频 32MB 超软指引 2MB（压缩候选）

"""《深夜茶馆》Stable Audio 3 small-sfx 音效（20-teahouse.md §8.2 SA3 条目，5 件）。
|

|

生成（GPU，flock 串行；模型已入缓存，HF_HUB_OFFLINE 可跑，见 env.d/sfx.sh）：
|

cd tools/stable-audio-3 && flock /home/xsl/SoundGame/.gpu.lock \

-p "<prompts>" --duration <secs> -o <staging>/teahouse.wav
|
||||
本脚本随后做后处理：自然修剪/去直流/8ms cos² 淡化/响度定档 → ogg q3 + m4a 128k
|
||||
→ 解码回读 QC：真峰值 ≤ -3dBFS、|直流| ≤ 0.001；超限降增益 + 重编，最多 3 轮。

prompt：20-teahouse.md §8.2 条目英文化。定档（§3.3 频带分离 + 操作音不抢人声）：

door_bell -8（铜铃两响，进门标记）、steps_in/out -12（脚步远低近高，床级）
