Subnets served per interface, pools, reservations, options at three levels, leases in SQLite saved before the ACK, ping and decline conflict checks, validated changes with history and undo, users and tokens, an audit log, a Kea importer, a sandboxed systemd unit and Debian packages. Tested with real udhcpc and dhcpcd clients in Docker (scripts/e2e.sh). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
