Deadline Ripple Mapper

Final delivery date: {{deadline}}.
Project/deliverable: {{deliverable}}.
Team members involved: {{team_members}}.
Unknown variables: {{unknowns}}.

Map the deadline ripple:
1. Final deadline → Last task (work backward)
2. Dependencies for each phase
3. Review/approval cycles needed
4. Buffer time recommendations (risk-adjusted)
5. Critical milestone dates
6. When each person needs to start
7. Early warning triggers (check-in dates)

Provide:
- Reverse-scheduled Gantt (key dates only)
- Owner and dates for each milestone
- What could cause slippage + contingencies
- Calendar blocking recommendations
