GET /api/clients returned "groups": null when there were no groups, because the
merged list was a nil slice. Found against the real cluster.
The console manifest, never applied before, had an image name that does not
exist here, no image pull secret or architecture selector (the resolver's pods
have both), and pointed at a Service (fancy-dns-admin) that is not there. It
now uses the registry image, the pull secret, and the existing fancy-dns-web
Service.

The address redirects page rewrote an RPZ ConfigMap through the resolver's own
service account, and the domains page rewrote allow_entries/block_entries in the
config file. Both become cluster objects like the rest.
AddressOverride is one name answered with fixed addresses (the name and
everything under it), exactly what an RPZ "name A address" line did. DomainRule
is a block or allow list of inline names. The resolver reads both with the
existing watch: overrides are rendered into the managed RPZ source the blocklist
manager already has, and rule names join the config's inline entries in the
merged overlay, so the file's config is never written to.
Names are checked to be DNS names or wildcard patterns before they are used,
because they are joined into line-oriented parser input and a newline or a
comment character in one would otherwise add a rule of its own.
The console edits both: the address-overrides and domains endpoints now write
objects. The console keeps its added rules in one DomainRule per action
(inline-block, inline-allow) instead of an object per name, and removes a name
from whichever DomainRule holds it, wildcard or not. An end-to-end test drives
the pages' endpoints and checks the resolver's answers.

The resolver kept its own query-log store (a bbolt ring, a live ring with SSE
fanout, rolling per-domain counters and dashboard time-series) for the console.
In a multi-node deployment each pod held a different slice of that, so every
view disagreed with itself, and the cost sat on the query path. Charts belong
in Grafana and log search in the log collector, so the store is gone.
internal/accesslog writes one JSON line per notable query to stdout. The default
is what was blocked and what failed (blocked, redirected, SERVFAIL, dropped,
refused); log_cached and sample_rate add ordinary answers for a debugging
session. Lines go through a bounded buffer to a single writer goroutine and are
dropped, and counted in fancydns_access_log_dropped_total, when the stream
cannot keep up, so a stalled log pipe can never stall a query. The config key is
access_log (the old qlog block is ignored, like any unknown key).
The metrics gain what the dashboard used to compute: fancydns_group_queries_total
by ACL group and outcome and fancydns_responses_total by RCODE. Removed with the
store: /api/dashboard, /api/logs, /api/logs/stream, /api/logs/clear,
/api/cache/top, the series rings, and the cache's per-name hit table, which took
a mutex and built a string on every cache hit.
Tests that read the old log now read the access-log lines; the contract test
drops the removed endpoints. The web console still calls them and is changed in
the next commit.

fancy-dns-console is a second binary holding the web UI, authentication and
every edit. It writes ClientGroup, BlockList and DNSZone objects through the new
kubeedit package and forwards all other /api routes to a running resolver
with its own key, dropping the browser's credentials, so it can run in the
cluster or on a workstation with a kubeconfig and nothing about the resolver's
placement matters. The resolver never imports kubeedit and the console is not on
the DNS path.
kubeedit validates every spec with the runtime's own converters
(kubesource.CheckGroup/CheckList/CheckZone) before writing, so the console
cannot store an object the resolver would reject. Zone edits keep the
file-based writer's behaviour: duplicate and below-a-delegation records are
refused, a delegation in a new zone also gives the zone its servers, and a
zone with no apex NS is never stored. Each object records the editing user in
an annotation; updates retry on conflict.
The resolver reports groups from ClientGroup objects as source "kubernetes" and
counter-only rows (the "(default)" bucket, or a group removed since) as
"history", and lists DNSZone zones as the editable ones. The console uses that
to leave the YAML's groups alone and to drop history rows, which the UI would
otherwise send back on save. Its GET /api/clients overlays the cluster's
current objects on the resolver's list, because the resolver only sees an edit
after its watch fires and a save made just after another would delete the
first.
An end-to-end test runs both halves against one fake apiserver: a group saved
through the console refuses queries, a zone built record by record answers
authoritatively, and a request with the resolver's own key is rejected by the
console.
