nx_gallery_keepalive.nx

nx_gallery_keepalive.nx -- SOVEREIGN Nishi supervisor for the gallery daemon. NO PowerShell, NO bash logic: the keepalive LOGIC is pure NishiLang (compiled by nx_cc_sovereign). It (a) holds the WSL VM alive -- a perpetually-running Nishi process keeps the VM from idle-shutting- down (the root cause of the daemon dying), and (b) supervises the gallery daemon: fork -> execve the daemon -> wait4; if the daemon ever exits/crashes, brief poll-sleep then relaunch. Last-mile launch only (incumbent used as launcher, never substrate): wsl.exe -e bash -lc 'cd <nxc2> && setsid ./runtime/_hdl_build/nx_gallery_keepalive.elf >log 2>&1 &' license_tier: ORIGINAL
