Counts when: A documented per-space loading or access face that changes how the load is built.
“If the door is at longside of container”
https://api.cargo-planner.com/api/2/schema/ (HoldDoor.longside)
“Each group can carry a door specification — width, height, and an At longside flag — for future-facing use. Door dimensions are stored with the set but are not currently enforced by the load calculation.”
https://cargo-planner.com/docs/equipment/set-builder/
A longside-door flag exists but no page says it changes how the load is built; the set-level door incl. At longside is stated as not enforced. Loading style (front-to-back / bottom-up) is a fill direction, scored under positioning. Open-top containers are "Loaded from above" as a description of the equipment, not as a solver setting.
