Time-travel read: the instance as it stood at the at watermark, reconstructed by folding its structural events. Property values that were marking-redacted or truncated in the event log surface as sentinel objects, not values.

The guest’s receipt for a settled check — issued when the check’s balance reaches zero, numbered from the outlet’s receipt series (R-{outlet}-{000001}) and chained by hash onto the property’s issued documents, invoices and credit notes included. A snapshot of what a UK simplified invoice needs (VAT Notice 700 §16.6.1: supplier name, address and VAT number, time of supply, what was supplied, per-rate VAT-inclusive totals and rates) plus the check number, outlet, server, business date, lines, tenders, tips and change. Not a VAT invoice: no recipient. A room charge prints as charged to the room, with the guest’s name and no card detail. Never edited after issue.
