Debt schedule model: amortization, covenants, and waterfalls

Design a debt schedule for {company_name}.

Inputs:
- Debt instruments and terms: {debt_terms}
- Interest rate assumptions (fixed/variable): {rate_assumptions}
- Fees and OID: {fees_oid}
- Required amortization and maturities: {amort_maturity}
- Covenant definitions: {covenant_defs}
- Cash flow available for debt service: {cash_flow_for_debt_service}

Output:
1) Debt schedule layout and formulas (begin balance, draws, repayments, interest, end).
2) Cash waterfall order and toggles.
3) Covenant calculation module and reporting table.
4) Stress test scenarios and breach flags.

Avoid assuming missing terms; request them explicitly.
