applyTheme mutated ~18 package-global lipgloss styles while every SSH
session's tea.Program read them concurrently from its own goroutine.
Pressing T or opening a new connection raced other sessions' View and
bled themes across users.
Styles now live in an immutable per-Model struct built by newStyles;
free formatter helpers that consumed the globals became Model methods.
Click any sparkline character to see data point details — approximate
time, latency, and up/down status. Esc dismisses tooltip without
leaving detail view. Uses existing BubbleZone infrastructure with
zone-relative coordinate math for index resolution.
Sites table with many rows exceeded the fixed content height,
pushing footer down. MaxHeight now clips content that overflows
while Height still pads shorter content upward.
Each tab returned different leading newlines (Sites/tables: 1,
Logs: 3, empty states: varies). TrimSpace content before layout
so JoinVertical controls all spacing. Remove leading \n from
footer since JoinVertical handles gaps.
Replace string concatenation layout with lipgloss.JoinVertical
and fixed-height content area. Footer now stays at the same
vertical position regardless of tab content height. Uses
lipgloss.Height() to dynamically measure header/footer and
fill remaining space.
- Extract divider() and emptyState() helpers to format.go
- All empty states now use bordered box with accent color
- Detail and alert detail panels get header/section dividers
- SLA label width 14→16 to match detail/alert panels
- Logs key hints moved from content to dashboard footer
- History/SLA panels use shared divider helper
- Show version in dashboard footer (wired from goreleaser ldflags)
- Cap name column at 35, raise sparkline minimum to 15 chars
- Preserve zebra background on group rows (was lost by style override)
- Group sparkline uses bullet • instead of heavy circle ●
Full-screen SLA report accessible via [s] from detail panel.
Computes uptime%, downtime, outage count, longest outage, MTTR,
and MTBF from state_changes table. Includes daily breakdown with
bar chart, switchable time periods (24h/7d/30d/90d), and
scrollable viewport. LATE/STALE treated as UP for SLA purposes.
Full-screen scrollable history view accessible via [h] from detail
panel. Shows all state transitions with computed outage durations,
event density sparkline for flapping detection, and summary stats.
- Detail panel STATE CHANGES now shows outage duration per recovery
- Event density sparkline highlights flapping periods
- Summary footer: event count, outage count, avg outage duration
- Vim-style navigation (j/k/g/G) + mouse scroll in history view
tui.go (1032→164) and tab_sites.go (993→482) violated "small functions"
and "testable in isolation" standards. Extracted 6 new files by concern:
- format.go: pure formatting functions (fmtLatency, fmtUptime, etc.)
- sparkline.go: sparkline rendering (latency, heartbeat, group)
- update.go: Update method decomposed into 15 named handlers
- view_dashboard.go: View, dashboard composition, tab bar, footer
- view_detail.go: site detail panel
- data.go: data refresh with extracted sortSitesForDisplay/filterSites
Added 17 unit tests for the newly-testable pure functions covering
format, sparkline, sort ordering, and filter logic. No behavioral
changes — strict move-and-extract refactor.
