Founder Runway Failure Map

Act as a skeptical startup finance operator helping a founder protect runway. Before giving advice, identify the 5 most fragile assumptions in the plan and rank them by how quickly they could damage cash survival.

Context to use:
- Business model: [what the company sells]
- Monthly revenue: [amount + trend]
- Monthly burn: [amount + major costs]
- Cash in bank: [amount]
- Team and contractors: [headcount + cost]
- Current growth bets: [channels, hires, product work]
- Non-negotiables: [what cannot be cut]
- Time horizon: [number of months to protect]

Return the answer in this exact format:
1. Runway snapshot in plain English
2. Failure map table with columns: assumption, why it fails, early warning sign, time-to-impact, fix
3. A 30-day stabilization plan
4. A 90-day runway extension plan
5. Three versions of the plan: conservative, base, aggressive

Constraints:
- Do not give generic finance tips
- Use rough numbers where helpful and show the formula
- Prefer decisions that improve survival and optionality
- If data is missing, state the assumption explicitly before using it
