# Payables Aging Rollforward Bridge

## Inputs
Two dated AP snapshots, invoice identifiers, posted invoices/payments/credits, adjustment evidence, currency and cutoff policy.

## Workflow
1. Align entity, currency, invoice keys and cutoff basis between snapshots. Preserve duplicates as exceptions.
2. Bridge opening plus new invoices minus posted payments/credits plus signed adjustments to closing. Tie every movement to source evidence.
3. Distinguish a date-driven bucket shift from a balance change. A row missing in the later extract is not proof of payment.
4. Return an invoice and total rollforward with unexplained movements. Do not pay invoices, send vendor messages or mark the period closed.

## Output contract
invoice key | opening | additions | posted payments/credits | adjustments | closing | unexplained | bucket movement

## Fictional acceptance test
Fictional opening $1,000 plus $300 new invoices minus $200 posted payments equals closing $1,100. If the later snapshot shows $1,050, report an unexplained -$50 movement rather than invent a credit.

## Review gates
Check 1000+300-200=1100. Remove payment evidence to force an unsupported-movement flag. Reconcile currencies separately.
