+---
+
+# Hardware Inventory
+
+This document is the physical inventory of lab equipment. It records models,
+quantities, product references, and concrete specifications.
+
+Role assignments for core network devices live in the
+[networking hardware reference](networking/hardware.md). Installed cabling
+lives in the [physical connection map](networking/physical-connections.md).
+IP addressing, VLANs, and other network configuration belong to the network
+documentation, not this inventory.
