- FxGuiServer: HWND_TOP (no longer always-on-top), /hide + /show endpoints, onStarted callback prints SF_FXGUI_PORT before plugin load (fast connect) - RenderFxJob: RealtimeFxChain (mutex+worker, SEH-guarded, bypass slots, deferred Vst3Fx dtor); --fx-gui split into parse/create/load-attach stages - main: FreeConsole unless SF_KEEP_CONSOLE; control type 6 SET_FX_CHAIN feeds g_fxChain on the audio loop; shutdown before CoUninitialize - plugins.py: CREATE_NO_WINDOW on both Popen paths - lib.rs: set_fx_chain command -> push_control(6) - app.jsx/nativeBridgeService: setFxChain sync from MasteringModal; panel close uses /hide + refs to fix closure bug; VstGuiEmbed rect refresh -> /show
