B1RestaurantSeatAssignment

• Restaurant seat assignment record - tracks which group is registered to which table (BL-58467, seat ownership).
  * Stored and serialized as a TArray on FB2HouseholdBiz. Kept independent of FB1RestaurantOrderTicket because
  * seat registration happens before any order exists (guide-to-seat precedes ordering).
  
  Two-phase gate: assignment alone does NOT open the seats (Restricted stays on for everyone, including the
  * assigned group, so a manually-possessed or wandering-in customer can never sit at a table that isn't theirs).
  * Only once bActivated is set (by the employee's guide-to-seat interaction) is Restricted lifted for these seats.

Property	Type	Description	Metadata
TableEntityId	FB1EntityId	Entity ID of the table (desk) unit registered to this group.
EaterIds	TArray	Entity ID of each registered group member (Eater). Parallel array with SeatEntityIds.
SeatEntityIds	TArray	Entity ID of the seat (chair) registered to each member, parallel to EaterIds.
bActivated	bool	Whether an employee has guided the group to their seats yet. False = seats remain Restricted for everyone (including this group).
bReceivingOrder	bool	True while an employee Coop is receiving this party's order. Runtime-only; restored assignments derive PendingOrder or PendingSeat from current seating.
GuideQueuedTicks	int64	Game tick of the most recently queued guide-to-seat attempt; -1 if none in flight. Covers the WalkTo-approach window before Coop connects, where a Coop-connection check cannot yet see the in-flight guide (BL-61977). Paired with GuideQueuedEmployeeId to detect the attempt ending early; also expires after a short window as a backstop so a silently failed/canceled attempt does not permanently block reassignment, since PendingGuide has no stall-timeout dismissal to recover a stuck flag. Cleared once bActivated is set. Runtime-only.
GuideQueuedEmployeeId	FB1EntityId	Employee entity queued for the in-flight guide-to-seat attempt tracked by GuideQueuedTicks; Invalid if none. Used to check whether that employee is still actually playing the guide interaction. Runtime-only.
OrderQueuedTicks	int64	Game tick of the most recently queued order-taking attempt; -1 if none in flight. Same WalkTo-approach gap as GuideQueuedTicks, before bReceivingOrder is set by the Coop step script (BL-61977). Cleared once bReceivingOrder is set. Runtime-only.
OrderQueuedEmployeeId	FB1EntityId	Employee entity queued for the in-flight order-taking attempt tracked by OrderQueuedTicks; Invalid if none. Runtime-only.
CreatedTicks	int64	Game tick when this assignment was created. Distinguishes a member's departure that happened during this assignment's lifetime from stale leave-state left over from an earlier, unrelated visit today.
