From `baseline.json`:

- Constraint: `payment_customer_fk`
- Source table: `sales.payment`
- Target table: `crm.customer`
- Ordered column pair: `(customer_id, id)` — `sales.payment.customer_id → crm.customer.id`
- Target in scan scope: **Yes** (`target_in_scope: true`)

**No**, this declared FK does not also point to `legacy.customer.id`; no second relationship is declared.
