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.

Inventory ledger entry per (property, room_type, business_date). The single source of truth for whether a room is sellable. physical is the underlying room count; sellable is the count exposed to channels after holds/walls; sold is occupancy as of the snapshot; oversell_limit is the operator’s declared headroom above sellable, which offsets cancellations and no-shows — declared by set_availability, moved by an applied sell-limit recommendation; declared_oversell_limit keeps the operator’s declaration (what a recommendation’s reset restores) and oversell_ceiling the most headroom a recommendation may set; out_of_order is the count of this type’s rooms blocked out of order this date (owned by the room_status_block verbs, never by set_availability); blocked is the count held by group blocks and not yet picked up (owned by the group-block verbs, likewise never by set_availability). The booking flow refuses at sellable - out_of_order - blocked + oversell_limit, and the validator on this type enforces 0 <= sold <= sellable + oversell_limit, sellable <= physical, 0 <= out_of_order <= physical, and 0 <= blocked <= physical on every write.

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