Fleet.vue's useFleetData() (60s telemetry.fleet-status/-alerts poll),
Server.vue's FipsNetworkCard.vue (15s fips.status poll), and Web5.vue's
Web5Monitoring.vue (30s system.stats poll — redundant with Home.vue's
own correctly-gated 10s poll of the same store) all armed their
setInterval in onMounted and only disarmed it in onUnmounted/
onBeforeUnmount. That was harmless before 02-04 registered their
owning views in KEEP_ALIVE_PATHS (the view was destroyed on every
tab-away, so the teardown hook fired every time); once KeepAlive keeps
the instance alive, the teardown hook never fires again and the poll
ran forever in the background regardless of which dashboard tab was
showing.
Gated arm/disarm to onActivated/onDeactivated, mirroring Server.vue's
own vpnPollInterval fix from 02-04 exactly. Added regression tests to
keepAliveLifecycle.test.ts mounting each real component under a
synthetic KeepAlive with fake timers; confirmed RED against the
pre-fix code (git stash) before confirming GREEN with the fix restored.
Full suite (95 files/788 tests), type-check and build all green.
keepAliveTabs.test.ts is byte-for-byte unmodified.
