The more I study the 5E I see it as a multicomputer or distributed system. The minicomputers were responsible for OAM and orchestrating the symphony over time, but the communications are happening across the CM which implements the Time/Space/Time fabric and a sea of microcontrollers. I think this clarification is worthwhile because it drives your point about faults in this computer-era and by extension this (micro)services-era home even more -- it's much less mainframe and more distributed system than commonly chronicled, which can be a harder problem especially with the tooling back then.
