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.

selected states stop changing font weight, buttons gain a pressed scale and scoped 120ms transitions with a reduced-motion override, every loading and empty state reserves its height, charts measure before first paint, hit targets rise to the 44px enhanced target where layout permits, long domains clamp to two lines on an unpadded inner span, chips and name cells truncate, tabular figures on counts and time columns, a z-index layer scale replaces magic numbers and fixes the dialog-over-confirm tie, history's empty state gains a clear-filters action, page headings balance, font smoothing and color-scheme land on the html reset.
