        // executes CMSSL/Program.cs at all. Found by diffing a fresh EngagementHost publish
        // against 217.216.78.142's live config before deploying: none of these had any other
        // registration source in that specific host's module set. Registered here directly
        // (rather than relying on some other co-hosted module happening to register the same
        // thing, e.g. PERM/OKR/FBCK for BaseEntityAppService<>/IQualifierFacade/IOutBox or DMS
        // for IVaultService) so CMS keeps working regardless of which sibling modules a future
        // host does or doesn't include — a harmless duplicate registration if a sibling already
        // provides one, per the same pattern DXP/PERM/OKR/FBCK/MM/etc. each already follow
        // (every module registers its own full dependency set, none rely on a sibling's).
