-====== Compute Repo (Project 22) — Structure ======
-===== Notes =====
-The compute repo (project 22) is a separate GitLab repository from the main vps/vps monorepo. It contains programs deployed to each compute host node, primarily used by HostDaemon.
-===== Repository =====
-  * **URL:** ''https://git.mammoth.com.au/vps/compute''
-  * **Project ID:** 22
-  * **Description:** Programs and scripts deployed to each compute host node
-  * **Used by:** HostDaemon, live migration, guest lifecycle management
