SPA (cmd/frontend/web):
- New "lb buckets" column backed by a 1s-debounced GetVPPLBState
fetch loop with leading+trailing edge coalesce.
- Per-frontend health icon (✅/⚠️/❗/‼️/❓) in the Zippy header,
gated by a settling flag that suppresses ‼️ until the next lb-state
reconciliation after a backend transition or weight change.
- In-place leaf merge on lb-state so stable bucket values (e.g. "0")
don't retrigger the Flash animation on every refresh.
- Zippy cards remember open state in a cookie, default closed on
fresh load; fixed-width frontend-title-name + reserved icon slot
so headers line up across all cards.
- Clock-drift watchdog in sse.ts that forces a fresh EventSource on
laptop-wake so the broker emits a resync instead of hanging on a
dead half-open socket.
Frontend service (cmd/frontend):
- maglevClient.lbStateLoop, trigger on backend transitions +
vpp-connect, best-effort fetch on refreshAll.
- Admin handlers explicitly wake the lb-state loop after lifecycle
ops and set-weight (the latter emits no transition event on the
maglevd side, so the WatchEvents path wouldn't have caught it).
- /favicon.ico served from embedded web/public IPng logo.
VPP integration:
- internal/vpp/lbstate.go: dumpASesForVIP drops Pfx from the dump
request (setting it silently wipes IPv4 replies in the LB plugin)
and filters results by prefix on the response side instead, which
also demuxes multi-VIP-on-same-port cases correctly.
maglevc:
- Walk now returns the unconsumed token tail; dispatch and the
question listener reject unknown commands with a targeted error
instead of dumping the full command tree prefixed with garbage.
- On '?', echo the current line (including the '?') before the help
list so the output reads like birdc.
Checker / prober:
- internal/checker: ±10% jitter on NextInterval so probes across
restart don't all fire on the same tick.
- internal/prober: HTTP User-Agent now carries the build version
and project URL.
