Bolder, more delightful frontend across all pages 2349f585ae

- app.css: replace flat --shadow-sm token with real shadows; add
  --shadow-card and --shadow-dialog tokens; add @keyframes status-ping
  and .animate-status-ping utility (outward ring ripple, GPU-composited
  via will-change) for live running status dots
- login: headline 5rem → 6.5rem with tighter leading/tracking; expand
  container to 460px; add sage-green dot grid texture layer beneath the
  mouse-reactive glow for industrial depth
- capsules: upgrade all running dots (header chip + row indicators +
  status bar) from opacity-fade to ring ripple; apply --shadow-dialog
  to Launch and Snapshot dialogs
- keys: apply --shadow-dialog to all three dialogs
- audit: remove duplicate @keyframes fadeUp and iconFloat (redundant
  with app.css definitions, audit's fadeUp also subtly diverged)
- sidebar: active indicator bar taller and thicker (h-5 w-[3px] → h-6
  w-1); active bg more vivid (accent/12%); label font-medium →
  font-semibold; team dialog gets --shadow-dialog

Add live stats page with metrics sampling and route split fee66bda50

- New sandbox_metrics_snapshots table sampled every 10s (60-day retention)
- Background MetricsSampler goroutine wired into control plane startup
- GET /v1/sandboxes/stats?range=5m|1h|6h|24h|30d endpoint with adaptive
  polling intervals; reserved CPU/RAM uses ceil(paused/2) formula
- StatsPanel component: 4 stat cards + 2 Chart.js line charts (straight
  lines, integer y-axis for running count, dual-axis for CPU/RAM)
- Range filter persisted in URL query param; polls update data silently
  (no blink — loading state only shown on initial mount)
- Split /dashboard/capsules into /list and /stats sub-routes with shared
  layout; capsuleRunningCount store syncs badge across routes
- CreateCapsuleDialog extracted as reusable component

Fix metrics correctness, redesign stats page 47b0ed5b52

- Replace stale snapshot read (GetCurrentMetrics) with live query
  (GetLiveMetrics) against sandboxes table — always returns correct
  zeros when no capsules are running
- Fix CPU reserved formula: running + starting only; paused VMs no
  longer contribute vCPUs (RAM reservation for paused unchanged)
- Merge top cards into 3 paired Now/Peak cards with colored accent
  borders (green/blue/amber matching chart colors)
- Move Live badge from Running Capsules card to page-level header
- Add colored category dots to card and chart headers
- Charts stacked vertically, flex-1 to fill remaining page height
- vCPUs chart color changed to blue (#5a9fd4), RAM stays amber

Move metrics to dedicated nav item, simplify capsules page 930da8a578

- Add Metrics nav item to sidebar with bar chart icon
- Create /dashboard/metrics page wrapping StatsPanel
- Remove tabs from capsules page (list is now the only view)
- Flatten capsules route: /capsules directly shows the list,
  removing the /list and /stats sub-routes
- Strip redundant title/subtitle from StatsPanel (page header
  provides context)

Fix metrics sampler to record zero-value snapshots when idle e3750f79f9

SampleSandboxMetrics previously filtered WHERE status IN ('running',
'starting', 'paused'), which returned no rows when all capsules were
stopped. This caused zero snapshots to be skipped, leaving the
time-series charts with no trailing data points instead of showing
the expected zero values.

Remove the WHERE filter so the query groups by all teams that have
any sandbox row. The per-status FILTER clauses on the aggregates
already produce correct zero counts for stopped capsules.

Also includes the per-VM RAM ceiling formula change (sum(ceil(each/2))
instead of ceil(sum/2)).

Move metrics to after templates in sidebar nav 45793e181c

Split CPU and RAM into separate side-by-side charts a69b0f579c

CPU (vCPUs) and RAM (GB) use different units and scales, so combining
them on a dual-axis chart was misleading. Each now has its own chart
card, laid out side-by-side.

Bolder stats page layout with stronger visual hierarchy b0e6f5ffb3

- Accent stripes: 3px → 5px; indicator dots: 6px → 8px
- Peak values step down to text-[1.714rem]/text-secondary so Now values read as the clear hero
- Now labels: semibold + uppercase for weight parity with the metric
- Cell padding py-5 → py-6; outer gap-7/pt-4 → gap-8/pt-6 for breathing room
- Chart fills: 7-8% → 11-13% opacity; lines: 1.5 → 2px
- Tick labels brighter (#635f5c), grid lines slightly more visible
- Running capsules chart: min-height 220 → 260px

Fix capsules table blink on background poll refresh 8d5ba3873a

Poll fetches now silently update data without triggering loading
states, spinner animations, or row fadeUp re-animations. Only manual
refresh shows the spin indicator.

Bugfix: cgroup2 related error inside the sandbox 7473c15f52

Add per-sandbox CPU/memory/disk metrics collection 9acdbb5ae9

Samples /proc/{fc_pid}/stat (CPU%), /proc/{fc_pid}/status (VmRSS), and
stat() on CoW files at 500ms intervals per running sandbox. Three tiered
ring buffers downsample into 30s and 5min averages for 10min/2h/24h
retention. Metrics are flushed to DB on pause (all tiers) and destroy
(24h only). New GetSandboxMetrics and FlushSandboxMetrics RPCs on the
host agent, proxied through GET /v1/sandboxes/{id}/metrics?range= on
the control plane. Returns live data for running sandboxes, DB data for
paused, and 404 for stopped.

Add 5m, 1h, 6h, 12h range filters to metrics endpoint 49b0b646a8

Maps each user-facing range to the appropriate underlying ring buffer
tier and applies a time cutoff filter. No new ring buffers needed —
5m/10m read from the 10m tier, 1h/2h from the 2h tier, 6h/12h/24h
from the 24h tier.

Minor improvement 88cb24bb86

Fix LIKE pattern injection in user email search 6eacf0f735

Escape LIKE metacharacters (% and _) in the email prefix before passing
to the SQL query, and enforce the documented '@' requirement to prevent
broad user enumeration. Move search logic out of TeamService into
usersHandler since it is a site-wide lookup, not team-scoped.

Push GetSandboxMetricPoints time filter into SQL 27ff828e60

The query was fetching all rows for a (sandbox_id, tier) pair and
filtering by timestamp in Go. For repeatedly-paused sandboxes the
24h tier can accumulate up to 30 days of data, causing up to 120x
over-fetching for a 6h range request.

Add AND ts >= $3 to the query so Postgres filters on the primary key
(sandbox_id, tier, ts) directly. Drop the redundant Go-side loop.

Add per-capsule stats detail page with live CPU/RAM charts ed7880bc6c

- New detail page at /dashboard/capsules/[id] with Stats and Files tabs
- Stats tab shows capsule info card (status, template, CPU, memory, disk,
  started, idle timeout) and two stacked Chart.js charts with live values
- Metrics API client with 10s polling and moving-average smoothing
- Capsule ID in list table is now a clickable link to the detail page
- Layout breadcrumb header (Capsules > sb-xxx) with back navigation
- Fix metrics sampler: use v.PID() directly as Firecracker PID since
  unshare -m execs (not forks) through the bash/ip-netns-exec/firecracker
  chain, so all share the same PID. Removes unused findChildPID.
