+# Network hub
+
+This hub links the core docs for how Clawdbot connects, pairs, and secures
+devices across localhost, LAN, and tailnet.

+## Core model

+- [Gateway architecture](/concepts/architecture)
+- [Gateway protocol](/gateway/protocol)
+- [Gateway runbook](/gateway)
+- [Web surfaces + bind modes](/web)
+
+## Pairing + identity
+
+- [Pairing overview (DM + nodes)](/start/pairing)
+- [Gateway-owned node pairing](/gateway/pairing)
+- [Devices CLI (pairing + token rotation)](/cli/devices)
+- [Pairing CLI (DM approvals)](/cli/pairing)
+
+Local trust:
+- Local connections (loopback or the gateway host’s own tailnet address) can be
+  auto‑approved for pairing to keep same‑host UX smooth.
+- Non‑local tailnet/LAN clients still require explicit pairing approval.
+
+## Discovery + transports
+
+- [Discovery & transports](/gateway/discovery)
+- [Bonjour / mDNS](/gateway/bonjour)
+- [Remote access (SSH)](/gateway/remote)
+- [Tailscale](/gateway/tailscale)

+## Nodes + bridge

+- [Nodes overview](/nodes)
+- [Bridge protocol (legacy nodes)](/gateway/bridge-protocol)
