# Bank Statement Period Continuity Check

Expose a gap or overlap between reconciliation statement periods.

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

## Inputs
Last reconciled statement ending date, next statement start/end, bank account ID and coverage evidence.

## Workflow
1. Match periods to the same bank account.
2. Compare next start with the day after last ending date as documented.
3. List gaps and overlaps without changing the entered ending balance.
4. Return source-period questions before transaction reconciliation.

## Output contract
account | previous_end | next_start | gap_days | overlap | missing_statement

## Fictional acceptance test
Fictional previous period ends Sep 30 and next starts Oct 3. Oct 1-2 lack coverage. A matching ending balance does not fill that two-day gap. Unknown prior statement date remains held.

## 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.
