# Add sentiment analysis to comments

Lightweight, self-contained feature. Comments exist, sentiment scoring doesn't.

## Scope

- Classify comments as positive/neutral/negative
- Use a lightweight local rule-based approach (no external API dependency)
- Store sentiment score per comment in DB
- Feed sentiment data into existing analytics dashboard (MPS-3)

## Notes

- No longer blocked by engagement signal weighting — analytics is live (MPS-3)
- Products with high positive:negative ratio could surface in analytics
- Keep it simple: rule-based first, upgrade to ML later if needed
