feat(new8/batch2): 《深海回音》abyss +《雨夜专案》detective 全套交付（多agent流水线：策划→资产→开发→测试→真资产复跑）
- abyss：game.js 242 断言全绿（剧本A-F六路径/氧气门三形态/sonarGate仲裁/结算死窗/双轨看门狗/radio 8项修复继承）；资产 148句+11key变体（电台滤波带内能量47-62%→69-80%） - detective：game.js 265 断言真资产下全绿（矩阵不变式独立重算/指证全路径/评级12组注入/VERDICT死窗/二周目变体）；真资产复跑回炉3处实现修复（无进展轨墙钟化/菜单暂停记账/停止播报真停声——mock时长掩盖的正确性bug） - 资产：TTS 539条×2格式、Mureka 7首 $0.21（累计$1.08/$2.00）、SYN12+SA3 19件（QC抓出1例AAC过冲并修复）、封面×2、check_all_assets 10游戏全绿（abyss 298/298、detective 279/279） - 平台接线：大厅双卡片、BUCKETS 增 abyss/detective 桶（H4 断言更新 10 游戏）、voice_text.json 10游戏991句 - 回归：14 套件全绿（10 playtest+guide+engine-voice+engine-input+api-smoke 12/12） - 设计偏差登记：abyss 7条/detective 9条（全为设计内部冲突按承诺清单/归因真话律取优）

"""《雨夜专案》Stable Audio 3 small-sfx 音效（批次 2，18-detective.md §8.2 SA3 条目）。
|
||||
|
||||
生成（GPU，flock 串行；模型 gated 走 hf-mirror，见 env.d/sfx.sh）：
|
||||
python3 gen_sfx_sa3.py --emit # 打印生成命令，原样执行
|
||||
生成 6 条原始 wav 到 gen/staging/sfx_sa3/detective_<i>.wav（顺序 = 下表 idx）。
|
||||
本脚本随后做后处理：修整（签名 earcon 按 max_s 压进 0.3-1.0s 量级——条目切换/
|
||||
指证选择前置音，长了拖慢导航）/去直流/8ms cos² 淡化/ 响度定档 → ogg q4 +
|
||||
m4a 128k（highpass=f=30，one-shot 前后垫 60/120ms 静音）→ 解码回读 QC：逐声道
|
||||
真峰值 <= -3dBFS、|直流| <= 0.001；超限降增益 + 首轮重编加 18kHz 低通，最多 3 轮。
|
||||
|
||||
prompt：paper_turn/gavel 直出文档英文原稿；sig_ge/sig_zhou/sig_scene/rain_swell
|
||||
为文档中文拟声条的英文化（信源：18-detective.md §8.2）。定档：
|
||||
gavel -4（裁决仪式拍）、paper_turn -7（导航细节反馈）
|
||||
sig_* -6（签名前置音，可辨不抢人声）、rain_swell -10（认罪链垫，压在 bgm/verdict 下）
