- 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}.

- Which never-used pool address a new client gets: sequential (the
lowest, as before), reverse or random, in the settings, a subnet or
a single pool (FIRST-LAST:ORDER). When no never-used address is left,
the one free the longest, whatever the order; returning clients keep
theirs.
- A subnet's pools are used in the order listed, or one at random
weighted by its never-used addresses. Pools now keep the order they
are given in (no more sorting by address).
- CLI --address-order and --pool-order; --add-pool of an existing range
changes its order in place. Web UI: per-pool order and a move-up
button, pool and address order on the subnet and settings pages.
- Kea's allocator: random is imported. Schema migration 5.

tls.acme names the certificate and jarl: the Jarl server and a token that
may only write the challenge record. Steward gets the certificate with
DNS-01 (lego), writing the record through Jarl's API into every view that
has the zone, renews it with a third of its lifetime left and swaps it
in without a restart. A check runs before every order: Jarl, the zone,
the token's permission, a test record, the zone's name servers, public
resolvers, clean-up; each step says what to fix. Staging by default.
With a certificate, each listener serves HTTPS and plain HTTP on one port
(redirecting plain HTTP, except from the server itself).
steward cert / cert check / cert renew, Server -> Certificate in the web
UI, GET /certificate, POST /certificate/check|renew. docs/certificates.md
and docs/jarl.md (the Jarl user and the token's grant).

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).
