1. Rate limiter cleanup goroutine now stoppable via Stop() channel
instead of looping forever. Prevents goroutine leak in tests.
2. Dead WindowSizeMsg branch in handleFormMsg removed — top-level
Update handles resize before forms see it.
3. Probe results sorted by node ID — map iteration no longer
reorders rows every render.
4. fmtAlertConfig takes models.AlertConfig directly instead of an
anonymous struct the caller builds inline.
5. Backspace no longer aliases delete — d is the documented key.
Prevents accidental delete-confirm on habitual backspace.
6. SLA daily buckets use time.Date day arithmetic instead of
Add(-i*24h) — lands on midnight correctly across DST transitions.
Replace ~150 bare status string comparisons with typed models.Status
constants (StatusUp, StatusDown, StatusPending, StatusLate, StatusStale,
StatusSSLExp). Single IsBroken() method replaces the duplicated
isBroken lambda in monitor.go and isDown function in sla.go.
Adding a new status value (e.g. DEGRADED) now requires one constant
definition instead of grep-and-pray across 16 files.
CheckResult.Status stays string — the checker is the boundary between
raw protocol results and typed status. Cast happens at the edge in
handleStatusChange.
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.
