Agent Development

The edge agent (digilan/edge/gateway) is a Go daemon on OpenBSD 7.8. It fetches the device config from Nexus, renders it into OpenBSD's own files (pf, interfaces, unbound, dhcpd, ifstated, iked, ospfd), applies it under a rollback guard, reports state over a WebSocket, and keeps the box reachable on its own: uplink failover, cellular recovery, relay link, self-update and self-heal.

• Structure — code organization, commands, the dev VM
• PF Generation — how pf.conf is generated
• Config Generation — objects, schedules, DNS, DHCP, validating output
• Rollback — the confirm-or-rollback guard
• State Reporting — what the device reports and how
• Uplink Failover — ifstated, probes and the egress group
• Cellular — 4G detection, dialling and recovery
• Relay Link — the WireGuard link to a relay, rungs and failover
• Self-Update — OTA download, verification and watchdog
• Self-Heal — known-good restore and the isolation ladder

Operator-facing settings and commands are in Agent Configuration.
