- A subnet is a deny-list subnet (the default: everyone not denied) or
an allow-list subnet (only clients allowed or with a reservation);
the deny list counts in both. Entries are MAC addresses, prefixes
(aa:bb:cc:*) or client IDs. A refused client gets no answer (DENIED
in the activity log, with an Allow button) or a NAK on renewal.
steward access, the subnet's Access tab. Schema migration 7.
- The activity log keeps each message's header fields and options,
decoded into words (dhcp4.Describe): the parameter request list by
name, client IDs, lease times. ▸ on an Activity row, steward
activity show N / --details, GET /events/{id}.

- interfaces.exclude in steward.yaml (names or shell patterns) leaves
interfaces out of GET /interfaces, the web UI's picker and
'steward interface list'. Subnets on them are still served.
- With the ping check on, active leases are pinged every minute; a
client that answers gets a last-seen time (leases.last_seen,
migration 4). Not answering never takes a client offline.
- The activity log filters by subnet (--subnet, the Activity page,
GET /events?subnet=).

- Activity: a client's MAC address opens its leases; "Only this" filters
the list to that client.
- Reservations: Online is a green online / grey offline badge.
- A subnet's leases: "Include ended leases" is a checkbox.
- Dashboard: "All activity" is a button beside the heading.

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).
