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.

- PauseBackend and ResumeBackend return an error (not bool) when the
backend is disabled, preventing an inconsistent state where the
health state says "paused" but enabled=false.
- DisableBackend and EnableBackend now log uniform backend-transition
lines with from/to instead of separate backend-disable/backend-enable
messages.
- CLI errors strip gRPC boilerplate ("rpc error: code = ... desc = ")
and display the server message in red (when color is enabled). Both
the interactive shell and one-shot mode use the same formatError path.
maglevc
- Rewrite '?' handler (birdc-style): show full command paths from current
position to every leaf, right-aligned help column, dynamic slot values
displayed as an indented block when cursor is at a slot position.
- Collapse show frontends/frontend, backends/backend, healthchecks/healthcheck
into single plural-noun nodes with an optional <name> slot. Allows
'sh ba' (list all) and 'sh ba nginx0' (show one) without ambiguity.
- Add 'config reload' command.
- Fix tabwriter ANSI alignment: continuation lines in transition output
now carry the same label() byte overhead as the header line.
- Fix broken Walk for 'set frontend' command: setFrontendPoolName and
setWeightValue were fixed-word nodes that couldn't capture user input;
mark them as slot nodes with dynNone.
- Add tree_test.go covering expandPaths, cycle detection, prefix matching,
and the full weight-command walk.
gRPC / proto
- Add ReloadConfig RPC: checks config then applies it to the running
checker, returning ok/parse_error/semantic_error/reload_error.
- Add logging to CheckConfig (config-check-start/config-check-done at
INFO level).
maglevd
- SIGHUP handler now calls maglevServer.TriggerReload(), sharing the
same code path as the gRPC ReloadConfig RPC.
docs
- Collapse show command documentation to use [<name>] optional syntax.
- Remove developer-facing 'Command tree and parser' section.
- Document 'config reload'.
