I'm just catching up here so there's a lot I'm missing, but I'll go back and comment on the issue of government offices.
I am not against the idea of perhaps consolidating some elected offices into appointed offices of another one (like we did with citizen diplomats and the citizen-Delegate). And on the issue of cabinets, we do already permit our executive officers to appoint assistants of various kinds. If we find that it's more conducive to administration and encouraging involvement, perhaps we could expand the duties of these appointed offices or make them more cabinet like or make that idea more clear in law.
The Citizen-Delegate, for example, can issue ambassador posts to regions or extraordinary posts for special negotiations, the Citizen-Sergeant already issues ranks within the Militia. Right now, the job of "Speaker" and internal administration have kinda fallen into once office while there's also a Citizen-Liaison post whose abolition is being discussed. Perhaps, just as the Delegate who handles external affairs, we could have the Citizen-Initiator be an internal administrator with the power to appoint various "ministers" recruitment, cultural events, education, communications etc. Perhaps this role should be separated from Speaker like functions such as vote administration and law keeping.
All that said, I do feel that all of these officers should ultimately serve at the pleasure of the Ecclesia and be legally subordinate to them, even if by virtue of their office they wield more influence (which they should if they're putting in that work). The powers they afford make them attractive and worth it enough in my eyes that we don't have to formalize them as being above the Ecclesia.
