Crate ifc_control 

Bounded IFC control semantics: permits, project orders, action requests, and performance history.

This crate owns the IfcControl subtypes that govern work rather than describe physical form. It stages them into a transaction and validates what the schema states; it does not implement approval workflow, authorization, or policy decisions, which are the concern of whatever system issues the permit.

Controls relate to the work they govern through IfcRelAssignsToControl. The crate owning the relating control writes that relationship, so this crate stages it for its own four controls and refuses any other.

Records are laid out by attribute name from one release’s table (#198). IfcRoot.OwnerHistory is required in IFC2X3 and optional from IFC4 on, so the writers that leave it unset refuse IFC2X3 with ControlError::AuthoringRequired; the *_with_owner_history variants bind the model’s declared release and take a caller-supplied IfcOwnerHistory (#202).

read_control and read_controls read the four controls back as borrowed Control views, by attribute name in the same declared release, together with the ControlAssignments that govern work (#100). A record that does not fit its release is refused, never read as absent.

IfcCostItem, IfcCostSchedule, IfcWorkCalendar and IfcWorkControl are IfcControl subtypes too, but they belong to ifc-cost and ifc-schedule: the crates split by domain, not by supertype, so those entities do not move here.
