[unlimit]

Ah. No, the thing that was blatantly wrong was my use of RDXDB.SetPackageMetadata().

TRUESYS.PKG = {
    "true_core",
    "true_unitframes",
    "true_multiframes"
};
 
    TRUESYS.MD = {
    "1.1",                                              -- infoVersion
    "Unlimit",                                          -- infoAuthor
    "Demon Soul US",                                    -- infoRealm
    "[email protected]",                                  -- infoAuthorEmail
    "manversuspixel.com",                               -- infoAuthorWebSite
    "(True) Adaptive User Interface",                   -- infoComment
    "infoIsShare",
    "infoIsImmutable",
    "infoIsIndelible"
};
 
RDXEvents:Bind("INIT_DATABASE_LOADED", nil, function()
    local version = RDXDB.GetPackageMetadata(TRUESYS.PKG[1], "infoVersion")
    local update
 
    if not RDXDB.GetPackage(TRUESYS.PKG[1]) then return nil; end
    if not version or version < TRUESYS.MD[1] then update = true; end
 
    if update == true then
        RDX.print("Updating (True) Adaptive User Interface to the latest version!");
        for i=1,3 do
            RDXDB._EmptyPackage(TRUESYS.PKG[i], true)
            RDXDB.SetPackageMetadata(TRUESYS.PKG[i], "infoVersion", TRUESYS.MD[1]);
            RDXDB.SetPackageMetadata(TRUESYS.PKG[i], "infoAuthor", TRUESYS.MD[2]);
            RDXDB.SetPackageMetadata(TRUESYS.PKG[i], "infoAuthorRealm", TRUESYS.MD[3]);
            RDXDB.SetPackageMetadata(TRUESYS.PKG[i], "infoAuthorEmail", TRUESYS.MD[4]);
            RDXDB.SetPackageMetadata(TRUESYS.PKG[i], "infoAuthorWebSite", TRUESYS.MD[5]);

        end
    else
        RDX.print("(True) Adaptive user Interface is up to date!");
    end
end);
 
RDXEvents:Bind("INIT_DATABASE_LOADED", nil, function()
    -- Define a local to package name and set package metadata
    local core = RDXDB.GetOrCreatePackage(TRUESYS.PKG[1]);
    local unitframes = RDXDB.GetOrCreatePackage(TRUESYS.PKG[2]);
    local multiframes = RDXDB.GetOrCreatePackage(TRUESYS.PKG[3]);

    end
 
    -- do stuff
 
end);
