   KTV_FILE_BASE: 文件服务地址，默认同 KTV_API_BASE 所在域
 
 步骤→模型映射（KTV_STEP_MODELS 字典，可通过环境变量覆盖各项）:
-  demucs_separating → ky-demucs-separate
-  asr_transcribing    → ky-asr-transcribe
-  subtitle_rendering  → ky-subtitle-render
-  face_detecting      → ky-face-detect
-  realesrgan_upscaling → ky-realesrgan-upscale
-  rvc_converting      → ky-rvc-convert
-  video_evaluating    → ky-video-eval-evaluate
-  songrate_evaluating → ky-songrate-evaluate
+  demucs_separating → demucs-separate
+  asr_transcribing    → asr-transcribe
+  subtitle_rendering  → subtitle-render
+  face_detecting      → face-detect
+  realesrgan_upscaling → realesrgan-upscale
+  rvc_converting      → rvc-convert
+  video_evaluating    → video-eval-evaluate
+  songrate_evaluating → songrate-evaluate
 
 本地操作（ffmpeg/ffprobe）不走 API。
