- cmd_gui with DESKTOP_STARTUP_ID: the entry is installed only after the fake Electron writes the reveal byte to HERMES_DESKTOP_READY_FD (spawn precedes install). - cmd_gui without DESKTOP_STARTUP_ID (control): install still precedes the spawn. - DeferredDesktopEntryInstall.finish(): an app that exits without revealing heals exactly once, after the exit. - linux-launcher-ready: one byte, fd closed, variable consumed; garbage/absent = no-op. Docs: user-guide/desktop.md explains when the entry write happens for grid launches.
