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.

A part or a product a house keeps — a spare part, a consumable, an amenity, linen, a minibar product, a laundry item, a cleaning product (hubOS’s materials, laundry products and minibar families). Keyed by code within its catalogue: a brand’s (material_at_brand, shared by the brand’s houses) or one house’s (material_at_property); define_material with a code the catalogue holds re-states it in place. Counted in its unit, which is fixed once any store holds it. A minibar product carries the sale_price a minibar task charges the in-house guest. active, or retired for good (the code stays taken). How much each store holds is its stock_level rows.
