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）

Browse Source 
- 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）

"""《深海回音》Stable Audio 3 small-sfx 音效（批次 2，17-abyss.md §5.2 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 12 条原始 wav 到 gen/staging/sfx_sa3/abyss_<i>.wav（顺序 = 下表 idx）。
本脚本随后做后处理：修整/去直流/8ms cos² 淡化（amb 床只去直流不淡化——游戏层
buffer.loop 循环，radio phone_ring/amb 先例）/ 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 轮补偿。
echo_metal_l/_r：文档 prompt 带 panned slightly left/right，但引擎无运行时 pan、
SA3 立体声分离度不可靠（dungeon 先例）——取「left」版生成源，mono 下混后 ffmpeg
pan 派生 _l/_r 预 pan 立体声（能量只在目标声道，脚本断言极性；dungeon side_* 工艺）。
prompt 均出自 17-abyss.md §5.2（英文原稿）；定档理由：
spark_flash/landslide -4（D2/D4 危机拍，前置 2s 渐强同窗）
echo_metal -5 / echo_groan -6 / surf_splash -6（信息音/叙事音，主层次）
valve_close -5 / bell_toll -5（道具 payoff 音）
echo_debris -7 / static_burst -8（垫在通话底下的纹理层）
amb_* RMS -26 / 峰值帽 -8（环境床，escape/adio amb 先例）
用法：.venv-tts/bin/python web/abyss/gen/gen_sfx_sa3.py [--emit]
