## @圖片審核Agent / @審核Agent visual review
- Score: 8/10
- Verdict: `visual_usable_needs_minor_caveat`
- Pass threshold for source candidate: 8/10
- Visible: red launch button, expected launch setup, tiny gray smoke puff, rocket droops/falls on the table, children shocked.
- No visible bubbles, speech bubbles, subtitles, logos, or watermark in source frames.
- Caveats: opening has a reference/character hold, so assembly trims 0.7s. Rocket reads more as drooped/fallen than obviously broken; acceptable for current p04 correction but can be strengthened in future by showing a detached fin or bent nose cone.

## @聲音Agent / STT audio QA
- Initial source STT with faster-whisper base: no English speech detected.
- Superseding stronger-model check: faster-whisper medium CUDA later detected `No way!` in this source clip.
- Corrected verdict: `provider_audio_pass_after_medium_stt_and_user_listening`.
- Required phrase: `No way!`
- Corrected decision: preserve ChatArtPro/provider original audio. Do **not** add controlled voice overlay for this source unless the user explicitly requests replacement.
- Lesson promoted to global workflow: a base-model STT miss on short/childlike/SFX-mixed speech is `STT_UNCERTAIN`, not an automatic provider-audio failure.
