+## Slice 9 - Business Overview Contract-Date Debt Age Signal Bridge
+
+This slice deepens the open-settlement quality family without crossing the evidence boundary into contractual overdue debt.
+
+Implemented now:
+
+- `debt_open_settlement_quality` now carries an optional `age_signal` derived only from dates found inside confirmed open-contract rows;
+- the pilot extracts contract-like dates from contract/document/analytics text, normalizes them to ISO dates, and computes a max age in days against the explicit as-of date;
+- the derived signal reports oldest/latest contract date, contracts with known start dates, and top aged contracts by age and amount;
+- the answer adapter surfaces this as `возрастной сигнал открытых расчетов`, not as payment-term delinquency, credit risk, or confirmed overdue debt;
+- `debt_due_date_aging_quality` remains a missing family, because dates embedded in contract names prove contract age, not contractual payment due dates.
