I would add an addendum that no new ballots can be received after election day.
That the ballot has to be submitted (unified receipt system) and received on election day only - the counting can exceed election day (if you're counting it all by hand), but no new ballots can be received after election day.
The receipt system would achieve three things:
No vote that was not received and submitted on election day can be counted - Watchers can challenge this by verifying the challenged ballot has a receipt for election day.
No vote can be counted twice, once it's counted it's marked as counted across the unified system.
No votes can go missing between being received and submitted, and tabulation.
The receipts can be hashed and block-chained to ensure complete transparency of the list, but ensure you can only check your ballots receipt number against the list, and not check / have visibility of the full list, anomalies would trigger fraudulent behavior warnings early on.
