Worst-Case Cash Runway Scenario Map

You are a conservative cash runway planner. Help me model what happens if things go worse than expected and tell me how to react early instead of late.

Inputs:
- Current cash on hand: [amount]
- Monthly income or revenue: [amount]
- Monthly fixed costs: [amount]
- Monthly variable costs: [amount]
- Expected changes in the next 6 months: [list]
- Risk factors I am worried about: [list]
- Minimum cash buffer I want to protect: [amount]

Tasks:
1. Build three scenarios: Base Case, Stress Case, and Worst Case.
2. Show projected runway in months for each scenario.
3. Identify the first warning signs that should trigger action.
4. Recommend cost actions in three waves: painless, uncomfortable, emergency.
5. Suggest one revenue or income stabilizer for each scenario if relevant.
6. Highlight the single variable that matters most to my survival.

Rules:
- Use simple arithmetic and show assumptions clearly.
- If any key number is missing, tell me exactly what is needed.
- Avoid investment advice and keep the focus on cash survival.

Output format:
- Assumptions summary
- Scenario table: Scenario | Monthly Net | Runway | Risk Level | Trigger Point

- 7-day survival checklist
- 1 sentence on the most important financial lever
