The pre-launch host drop/rejoin re-stream re-creates every mech at mission launch; the LOBBY-built gauge tree kept attribute pointers into the freed first-stream mechs, every widget Execute AV'd, and the BT_DEV_GAUGES SEH guard (Gauge::GuardedExecute, GAUGE.cpp:618) disabled each one PERMANENTLY (rate=0, no rebind) -- the frozen dev-gauges window of incident #12. The authentic engine flow only tears the tree down at mission transitions (Application::Shutdown -> gaugeRenderer->Shutdown() -> ShutdownImplementation -> Remove(0), APP.cpp:787 / GAUGREND.cpp:3264); the re-stream bypassed it. Fix: BTL4GaugeRenderer::TearDownForViewpointRestream() performs the ENTITY-BOUND half of that same ShutdownImplementation sequence, in order (gaugeAlarmManager->RemoveAllAlarms() -> Remove(0) -> moving/static entity grid Clear), keeping the mission-scoped state (warehouse, graphics ports, interpreter, controls-owned L4Lamps -- RemoveAllLamps would delete them behind the buttonGroup's &lamp->automaticValue registrations). Called from BTL4Application::MakeViewpointEntity before ConfigureForModel("Init") on any viewpoint RE-make -- that handler runs once per stream (the incident log's [ctrlmap] installing x2) -- so the tree rebuilds bound to the NEW mech via the renderer's existing lazy build. Sentinel: "[gauge] viewpoint re-stream: tearing the gauge tree down for rebuild". Verified with the 2-instance relay harness (port 15600, MP_RELAY.EGG, the incident sequence): join A (dev gauges) + B, kill B by exact PID at WAITING FOR OPERATOR LAUNCH, rejoin B, operator launch. Pod A re-streamed (2x ctrlmap install, 4x zonebuild), logged the sentinel, and post-launch the docked composite is fully live (mission clock/heading/radar advancing between BT_SHOT frames) with ZERO [gauge-fault] DISABLED lines (the incident had 11).
