The spatial hierarchy: Site, Zone, Rack, Level, Slot

Loqorina models a warehouse as a hierarchy of five node types. Every node in it has a stable ID and, usually, a QR code.

• Site: one physical location. This is also the billing unit: if you run two warehouses, you have two Sites, each its own subscription.
• Zone: a functional area within a Site, like receiving, storage, or packing. Zones are drawn as polygons on the floor.
• Rack: a parametric storage unit generated from a few numbers (bays, levels, dimensions), not hand-modeled.
• Level and Slot: addressable positions within a rack. A Slot is the leaf of the hierarchy: the smallest place an asset can be.

Assets sit on top of the hierarchy, not in it

An asset (anything trackable: a pallet, a bin, a piece of equipment) isn't part of the hierarchy itself. It has a current location, which is a pointer into the hierarchy above, and a full movement history. The Assets section of this documentation covers that in detail.

Why this shape, not something looser

A fixed hierarchy means every location has one unambiguous address, which is what makes search, QR codes, and the occupancy views work without ambiguity. It also means a location can't be described two different ways by two different people, the way a loose text field can drift.
