get_logs needs a unit from an allowlist (router-*, kea, unbound, networkd,
nftables, ddclient, acme, sshd, kernel). API tokens are valid for 1, 7, 30
(default) or 90 days, or without limit. The overview and the Changes page
say which token made the unapplied changes.
options.json (router://options) no longer holds the options' source paths:
they differ between builds of a release, so a router rebuilding itself
offline had to build the file and failed (found by the update test).
Web UI: panels flow into columns on wide screens and the width is no longer
capped; on phones the navigation is a menu button; the Advanced page uses
panels; VLAN dropdowns show their chosen names; the duplicate WireGuard
heading is gone.
basic: a subtest for wan -> local rules.
SPECS.md is now the only document (decisions, how each part works, and what
is not done yet); PLAN.md is gone.

router.firewall.nat replaces the dnat/toPort/hairpin fields of the filter
rules. Filter rules gain natOnly, and may use wan with log and rate limit
in the web UI. The Firewall page edits the NAT table and can add the
matching allow rule. Settings schema 1 (migrations/1.jq) converts old
forwards.

Kea skips interfaces without carrier when it opens its sockets and only
looks again on a reload, so a LAN cable plugged in after Kea started got
no DHCP until a restart. networkd-dispatcher now restarts Kea when a DHCP
LAN gets carrier (a restart: a SIGHUP while Kea is starting ends it). The
rule script is the same for every configuration and reads the interfaces
from /etc/router/dhcp-interfaces, so the device never has to rebuild it
(writeShellApplication's shellcheck could not be built offline).
The web UI refused every login from a browser with "forbidden": under
Referrer-Policy no-referrer browsers send "Origin: null" with form posts.
Use http.CrossOriginProtection (Sec-Fetch-Site, then Origin) and a
same-origin referrer policy.

Extend router.firewall.rules with a reserved `wan` source zone: DNAT
(dnat, toPort), port ranges, source allow-lists, per-source rate
limits, logging and optional hairpin NAT. IPv6 is opened only by
explicit pinholes. Build-time assertions require WAN rules to name a
destination, protocol and ports so a typo cannot expose a whole zone.
Covered by the basic/pppoe VM tests and the assertion tests.

LANs can sit on an 802.1Q VLAN (`vlan` on a trunk `interface`); networkd
creates the device and brings the trunk up. LANs belong to a named `zone`
(default: their own name). Traffic inside a zone is forwarded freely, traffic
between zones is denied unless a `router.firewall.rules` entry allows it
(protocol, ports, optional destination inside the target zone).
Internet access is now opt-in per LAN (`internet`, default false), replacing
the previous allow-out default. Assertions reject unknown zones, bad
destinations, duplicate devices, over-long device names and a WAN trunk.
Kea subnet IDs now come from the network address so adding LANs does not
renumber them and orphan persistent leases.
Tests: a five-VM `vlans` check (untagged + two VLANs, shared zone, one-way
rules, per-host destination restriction), new assertion cases, parseNet unit
tests, and shared test tooling in tests/common.nix.

IPv6: router.wan.ipv6.enable mirrors the existing uplink config (DHCPv6 with
WithoutRA=solicit, delegated prefix). The ISP delegates a single /64, so
exactly one LAN may claim it via router.lans.<name>.ipv6.pd (asserted); other
LANs stay IPv4-only. SLAAC only, no NAT66.
PPPoE: router.wan.ipv4.type = "pppoe" runs pppd on an optional VLAN of the
uplink, with the password read from a file at service start (never the Nix
store). NAT, forwarding and MSS clamping (MTU 1492) use the derived PPP
device; native IPv6 stays on the untagged link.
Tests: basic.nix is parameterised by uplink type; the pppoe variant uses a
fake ISP with pppoe-server (VLAN 7, CHAP). Both variants cover IPv6 PD, SLAAC,
routing without NAT and WAN-deny. Assertion tests gain PD/PPPoE cases and a
full-system evaluation step.

Add an IPv4 helper lib (parse, netmask, cidr, overlap) and derive
router.lans.<name>.ipv4.subnet from address and prefixLength instead of
requiring it twice. New assertions reject invalid addresses, DHCP pools that
are reversed, outside the subnet or contain the router address, and
overlapping LANs.
Add `lib` unit tests and an `assertions` check that evaluates broken configs
and compares the exact error messages.

driverInteractive uses the full QEMU build, which opens a GUI window per VM.
Pass -display none for the interactive nodes so `nix run .#lab` stays in the
terminal.

router.* schema (wan, lans, dns.forwarders) compiled to systemd-networkd,
a generated nftables ruleset with NAT, Kea DHCPv4 and Unbound, plus build-time
assertions against lock-out and interface conflicts.
tests/basic.nix is a three-node VM test (upstream/router/client) covering WAN
DHCP, LAN DHCP and DNS, NAT, WAN-deny and LAN SSH/ping. `nix run .#lab` boots
the same topology in tmux with one console pane per VM and the driver REPL.
