Problem: Claude was cutting clip exactly at last transcribed word of chorus,
but in real songs:
- Singer holds last note 1-3s longer (still meaningful)
- Outro 'ej-ej-ej' / 'oh' / 'yeah' may not be transcribed as words
- Result felt like 'incomplete chorus' even though SRT was correct
Fix has two parts:
1. Prompt enhancement:
- Ask Claude to add 1-2s padding AFTER last chorus word
- Explicit example with timing math
- Mention outro fillers (ej-ej-ej, oh, yeah)
2. Post-LLM extension logic:
- After Claude returns clip range, scan corrected_segments for
segments overlapping or starting just after current end
- If next segment is within 1s pause and ends within max_duration+5s,
extend clip to include it (with 0.3s breathing room)
- Hard cap at max_duration + 5s to prevent unbounded extension
This ensures chorus naturally trails off rather than being cut mid-emotional-peak.
