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 maintenance request, typically against a room or venue. Tracks severity (cosmetic through to safety) through an explicit lifecycle: assign, schedule, start, complete (with a resolution), void (with a reason). Whether the room is out of order while the order is open is never a flag here — it is a real room_status_block held via work_order_holds_block, minted through the same code path as take_room_out_of_order and released on completion. The order is a thread (2026-10-13): its work_order_entry lines log notes, time, parts, hand-offs, the postponement and the resolution; it may name the equipment it is for (work_order_for_asset, its id carried as asset_id) and the guest stay that reported it (work_order_reported_by_stay), and postpone_work_order defers it to a named date (resume_work_order brings it back when the date comes). A hand-off on the thread stamps delegated_to_role until the order closes. Since 2026-10-15 a fault is for a room (work_order_for_room) or a public area (work_order_for_area, create_public_area_work_order), never both; it may name the room element it is in and the fault_type it was raised from; and it carries its holder’s id (assignee_id, or a worker group’s group_id) beside the edge every assigning verb moves.

Malformed at, or the object’s history predates structural event images and cannot back a faithful reconstruction.
