Item 130, G1 walk notes N12 and N13.

Why. The base seed dated each paying check a fixed step after its invoice, so an invoice made late in the seed's span had a check from the future. The aging counts an application only on or before its as of day, so it showed that invoice open while the invoice read PAID, and the dashboard's Outstanding AR carried the same figure. The statement dated every row from the subledger row's stamp, which the base seed left at the moment it ran.

What changed

• Seed: a check the rule would date later is received on the seed's own day (chosen over leaving the invoice unpaid because the walk wants the history paid as designed; an invoice dated after the seed's day is left unpaid, and the seed no longer dates an invoice past that day). The base seed restamps its subledger, payment and ledger rows to the documents' days (new RestampDay in the AR core, stamps only).
• AR core: a payment received, an application, a credit memo application, a write off and both refunds dated after the business day in the branch's time zone are refused in words (400 naming the field). Void and reversal acts are not covered: their day is always computed on the server.
• Statement: each row is dated from its document (invoice day, credit memo day, received day, applied day, refunded day; a void or a reversal by its own day); the opening balance, the period and the order split on that day.
• Found on the way: the aging by customer answered 500 on any page that was not the last (an empty group id in the cursor). Fixed with its own red leg.

Red legs, each committed alone first

1. TestDemoImport/no money is dated after the seed's day and the aging agrees with the documents
2. TestDemoImport/the dashboard's Outstanding AR equals the aging summary's total (and the documents)
3. TestARRefusesAPaymentReceivedOnADayToCome, TestARRefusesAnApplicationOnADayToCome
4. TestARStatementDatesEachRowFromItsDocument
5. TestARAgingByCustomerPagesThroughItsCursor

Existing tests that relied on a later day (three, listed for the reviewer): TestARDiscountTakenAndReversed (late discount case now an invoice whose discount date has gone, applied today) and two POS payment tests that used a day far ahead as a stand in for any day (now a day in the past).

Goldens moved (clockwindow, gl_accounts_entries, reporting_reports), with a CONTRACT-CHANGES row. No wire shape changes.
