Dev: OS/2 → ArcaOS install & update platforms (manual vs automatic)

ArcaOS (Arca Noae) is a proprietary OS built on IBM OS/2 Warp 4.52. Software arrives over the Internet three ways: the netlabs RPM/YUM port, classic WarpIN .wpi self-installers, and ANPM (a native GUI over yum/rpm). A paid Support & Maintenance subscription adds a private YUM repo, but downloading/ applying is always user-initiated.

No Snap-style background auto-updater. The closest is the user-run yum.

WarpIN (`.wpi`)	✓	—	None — download `.wpi` and run	netlabs WarpIN	https://trac.netlabs.org/warpin	GPL (OSS)
ANPM (Arca Noae Package Manager)	✓	—	GUI over yum/rpm; queries remote repos on demand; also handles WarpIN	Arca Noae	https://www.arcanoae.com/wiki/anpm/	GPLv3
Support & Maintenance subscription	✓	—	Portal download (not background): reserved YUM repo + Download Center between ISO releases	Arca Noae, LLC	https://www.arcanoae.com/	Proprietary service

WeKan / Electron applicability

Only theoretical — OS/2 has just old/limited Node ports and effectively no Electron, so a modern WeKan desktop build would not run; at best a very old build might. Browser → hosted server is the realistic path.
