A CPU/RAM/Disk history graph over selectable ranges (1h/24h/7d/30d) on the server
detail page, backed by a persisted time series (the live 15s view stays cache-only).
- metric_samples table (server_id cascade, cpu/mem/disk %, load, sampled_at indexed).
- clusev:sample-metrics (scheduled every minute, mirrors clusev:wg-sample): persists
one row per server from the cached live reading, prunes beyond --retention (30d).
- MetricHistory::series() buckets + averages samples for a window; empty buckets stay
null so the chart shows gaps, not fabricated values.
- Servers/Show: range selector + a gap-aware SVG line chart (theme-token strokes,
R3-compliant, mirrors the dashboard chart). historyRange is clamped via setRange()
and the updatedHistoryRange() hook (it's a public, client-settable property).
Codex review: fixed a right-edge bucket off-by-one, clamped percentages on write, and
guarded the public range property against direct client values. Browser-verified: the
chart renders with data, range buttons, legend and gaps, zero console errors. 447
tests green, pint clean.

Two fixes the operator asked for:
- The "what's new" preview was empty. availableChangelog fetched CHANGELOG.md at
ref="0.9.50", but release tags are "v0.9.50" — the raw fetch 404'd and the
panel silently stayed empty. Use the v-prefixed tag as the ref. The existing
test masked it with a wildcard fake; tightened with Http::assertSent.
- The sidebar now shows a "1" badge on the Version item when an update is
available, so an update is visible on every page, not only the Versions page.
Driven by a new ReleaseChecker service: updateAvailable() is a pure cache read
(no network in the sidebar); a scheduled clusev:check-update (every 30 min,
anonymous/read-only) keeps the cache warm so the badge is accurate even before
the operator opens the Versions page.
Refactor: the remote tag lookup (fetch + newest-version) moved out of the
Versions component into ReleaseChecker; the component delegates. nav-item gains
an optional badge prop.
Tests: ReleaseChecker (cache-read update-available, refresh caches, command warms
cache, sidebar badge renders only when available) + the v-prefixed-ref assertion.
371 pass, Pint clean, /versions loads 200 with no console errors; badge + the
"What's new in v0.9.50" panel verified in the browser. Lang parity kept.
