The Overview page takes the decided visual language (specs/ui-visual-redesign.md): four centred totals with their Activity links, a smoothed area chart of total and blocked queries with point hover and a tooltip centred beside the point, a stacked client chart in eight distinct hues plus one Other band that is always a series, and a card row with the cache hit rate, the query types as a single-hue ramp ring, and the upstream breakdown. The count axis grows its margin with the widest grouped tick and draws whole-number ticks only.
GET /api/overview takes a client parameter; the scoped read uses idx_query_log_ts and the cache keeps scoped slots. The device selector beside the period selector is URL state, so a scoped view is a link, and the tile links carry the scope into Activity. The route reduces a pasted IPv6 scope to the RFC 5952 spelling the logger stores, mapped addresses included, and drops anything that is not an address. A failed device list says so under the selector with a retry.
All measured quantities go through admin/src/lib/format.ts: grouped counts, two-decimal percentages, one-decimal rates, durations as the two largest nonzero units. Identifiers, configured values and preset labels render as written; the module header states that scope. A sweep test refuses toFixed, toLocaleString, Intl.NumberFormat and padStart anywhere else.
Chrome: one 4px radius from the metrics constants, shared Card with a prominent title and a one-line description on every panel, the settings form sections on the same card with a floated legend, the sidebar grouped into Monitoring and System with a status block (protection, queries per minute on Overview, uptime), keyboard-focusable table scroll wrappers, and the accent darkened to 5.43:1 on its wash.
Not built: the spec's ranked-list primitive, which has no consumer and no API rows. Codex reviewed sessions B to D over five rounds (thirty-three findings fixed, thirteen rejected as non-quantities); the owner skipped a sixth round.

the upstream, blocklist source, and safe search enable controls mutate the row the moment they move, so they now carry the switch role via a shared drawn rac switch with a 44px hit area, a focus-visible ring, and naming modes made exclusive by a discriminated union. safe search supersedes its one-commit-old checkbox form, and the file-authority guard now names the switch role instead of relying on the bare input selector.
settings and upstream writes now follow a prepare, commit, publish, retire
contract: candidates are built and validated before the database transaction,
published as infallible pointer swaps, and old generations retire after their
readers drain. per-query policy values snapshot once per query; upstream pool,
cache, rate limiter, sessions, api limiter, log sink, blocklist scheduler and
the query-log queue each gained one named live operation. restart_required
shrinks from every scalar key to the bind keys and web.enabled; the admin ui
drops its restart notices for everything else. file mode is unchanged.
