### Session 3: UX & Sales Pitch (30-45 min)
- Design user flows for each feature
- Create demo script with talking points
- Plan sales presentation
- **Outputs:** UX wireframes, demo script, pitch deck

### Session 4: Implementation Planning (45-60 min)
- Break down each feature into sprint tasks
- Estimate build times
- Plan deployment strategy
- **Outputs:** Sprint backlog, task breakdown, deployment checklist

### Session 5: Guardian Council Validation (60-90 min)
- Synthesize all outputs from Sessions 1-4
- Validate against ethical guidelines
- Generate final intelligence dossier
- **Outputs:** Final dossier, recommendations, go/no-go decision
