Digiweb's BRAS answers PADI only on a single-tagged ISP VLAN (pon-isp,
10); the double-stacked wan-pon (131) transport never got a PADO because
the UniFi access switch can't push the outer tag onto already-tagged
ingress frames (no QinQ/tag-stacking). Attach VLAN 10 directly to the
physical `lan` link for now.
Kept reversible via a `wanStacked` flag: flip it back to true to restore
the 131->10 stack once a QinQ-capable device sits in front of the ONT.

The outer WAN VLAN carries the inner VLAN's frames, whose 4B 802.1Q tag
counts as payload at this layer. To fit the inner's 1508B baby-jumbo
payload plus that tag it needs 1512, not 1508. Harmless before only
because the physical `lan` (9000) absorbed the extra bytes; this makes
the outer's MTU literally reflect what it transports.

Capture what this session surfaced: the routing-common indexed-module
active/backup pattern, VRRP VIPs for gateway+DNS, the wan-online.target
convention, the networkd helper locations, and the "boxes not fleet"
terminology. Also note the fish login shell caveat for ssh scripting.

Clients were handed both routers' real addresses as resolvers, so a downed
router meant per-query resolver timeouts. Serve pdns-recursor on the VRRP
VIPs (with non-local bind so the backup can pre-bind them) and advertise the
VIP via kea and radvd, so DNS follows the master. untrusted advertises
Cloudflare over v6 to match its v4 config.
ipsec started before the WAN's public IP was up: stream's wan carries a
static modem address that satisfies wait-online before the DHCP lease, so
libreswan loaded its mesh conns (left=<public IP>) unoriented and never
initiated. Gate stream's wan-online.target on the DHCP default route
instead, and mkForce ipsec onto wan-online.target only (dropping the
strongswan/libreswan multi-user.target pull-in) so the gate actually holds
on both boxes.

river's WAN moves to a PPPoE session (Digiweb, over VLAN 10 with baby-jumbo
1508 MTU) driven by pppd, with its ip-up/ip-down hooks toggling a new
wan-online.target. stream keeps its DHCP WAN, so the existing 50-wan /
50-wan-ifb networkd config moves out of routing-common into stream, and the
shared consumers (ipsec, ipv6-clear-default-route) now attach to
wan-online.target instead of depending on systemd-networkd-wait-online@wan
directly.

Bump runner labels to node 24 / Trixie and Ubuntu 26.04. The upstream
module now generates the runner config from the `settings` option and
wires `ExecStart` itself, so drop the hand-written config file and
`ExecStart` override.

`check-system` evaluates a NixOS config without building it; `ssh-machine`
SSHs to a system or home by name, resolving the target and ssh options
from its `deploy-rs` node. Document both in `AGENTS.md`.
