The ⿻ principles of RadicalxChange and Plurality that sit above the three loops and decide where the surplus of a positive-sum system goes: openness, agency, fairness, regenerativeness, by design rather than by promise.
Any realisation flywheel with a data network effect faces a temptation the platform economy has already succumbed to: becoming the extractive intermediary that captures the surplus of a nominally positive-sum game. The plural principles, data sovereignty, co-ownership, interoperability, exit, are what keep the surplus with the players.
The constitution is not decoration. Without fairness by design there is no granted trust; without granted trust, no data contributions; without contributions, no evidence flywheel. The Plural Stack Assessment is its measurement discipline: it tests whether a service delivers plural properties by architecture rather than by promise. We do not operate a fourth loop at the polity scale; we align with the movement that does, contribute measurement, and let its principles govern our own architecture.
