## Quick Answers

### Q: Keep Meilisearch?
**A**: YES ✅
- pgvector = semantic search (AI-powered)
- Meilisearch = full-text search (keywords)
- Together = fast + relevant

### Q: Use Hatchet?
**A**: YES ✅
- Already in .env
- Perfect for scheduled tasks
- Free tier covers needs
- Easy Go SDK integration

### Q: Use Temporal?
**A**: NO ❌
- Overkill for TraceRTM
- Hatchet is better fit
- Operational overhead
