The model
A single decision loop, inside a closed web of checks.
The people are sovereign. Their mandate is formed honestly, carried out competently, measured openly and corrected as it runs, with every power checked, including the bodies that do the checking.
What this adds to the original concept. The early sketch showed experts and a decision loop, but left out who authorised them. This model puts the people back at the source: the mandate is actually formed (electoral reform sits inside the picture, not beside it), powers are separated under a constitutional court, outcomes feed back as a measured signal, and the integrity body is itself watched, by rotating citizen juries that guard the guardians. Around the loop sit the fiscal constitution, the territorial settlement of the Union, justice and the use of force, citizenship, and the defence of the constitution against those who would dismantle it.
