Current owner of this slot

float SlotValidAfterTime 

Slot is invalid until world.timeseconds is >= this value (allows temporary disabling of slots)

How far auto adjust code traces forward from lean fire point

to determine if the lean has a valid fire line

CoverSlotMarker SlotMarker 

Slot marker to allow the slot to exist on the navigation network
