# Debt Maturity Principal and Interest Map

Separate debt principal maturity from interest expense and cash timing in a model review.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Debt IDs, maturity dates, contractual principal schedule, interest policy/rates, payment dates, opening balances and currency.

## Workflow
1. Match each tranche and maturity version; no renewal is assumed.
2. Map principal repayments and interest separately to their supplied dates and statement roles.
3. Reconcile principal opening plus draws minus repayments to closing; hold missing repayment timing.
4. Return maturity concentration and missing evidence without refinancing advice or payment.

## Output contract
tranche | maturity | principal_due | interest_basis | cash_date | expected_principal_close | renewal_unknown

## Fictional acceptance test
Fictional opening debt 1000, new draw 200, principal repayment 300 yields 900 close. Interest 40 does not reduce principal under the supplied noncapitalized policy. A maturity tomorrow does not prove renewal is arranged.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
