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 list an attendant ticks — or a supervisor inspects against — for one housekeeping task type, optionally one room type (checklist_template_for_room_type). A brand standard (checklist_template_at_brand) or the house’s own (checklist_template_at_property); a task resolves the most specific active template: the house’s for its room type, the house’s for every room, the brand’s for its room type, the brand’s for every room. required_for_completion makes complete_housekeeping_task refuse until a checklist_result for this template is recorded against the task — hubOS’s ‘checklist for inspection’ building toggle, per list instead of per building. One active template per (scope, task type, room type): re-defining one revises its items in place. A public-area task type’s list may name a kind of area instead (applies_to_area_kind, 2026-10-14): an area’s task resolves the list for its kind before the list for every area, at the house and then the brand.
