NortheBridge/luminalshine is a Sunshine-compatible game stream host for Moonlight. Prior to version 26.05.0-rc4, a latent gap exists on a default install, the file at "src/platform/windows/misc.cpp" lives at "C:\ProgramData\LuminalShine\config\apps.json" and is created by the "SYSTEM" service. Under Windows' default "C:\ProgramData" inheritance, that gives "BUILTIN\Users" only Read+Execute — not writable — so the canonical EoP doesn't actually trigger on a vanilla install. Version 26.05.0-rc4 contains a patch for the issue. As a workaround, use default condition DACLs for "ProgramData".
