   - Evidence: logs/step9_master_probe.json and worker probe confirm master narration duration 1043.300s.
10. [completed] Run ASR on master audio for word timestamps
   - Evidence: script/asr_master_words.json and logs/step10_asr_master.json exist.
11. [completed] Create subtitles from source text mapped to ASR word timestamps
