SIGNAL separates authority across layers so that participation is meaningful without democratizing truth, and expertise is disciplined without becoming technocratic.
The System Layer holds versioned, inspectable objects (signals, observations, allocations, regimes, lenses).
The Wiki Layer hosts structured expert discourse that can propose changes to system objects through defined pathways.
The Public Square hosts civic interpretation and contextualization, but cannot directly change system objects.
Contributors propose edits, sources, and candidate objects.
Stewards guide process, activate governed states (such as disputes), and ensure procedural integrity.
Expert validation may exist as a distinct, explicitly scoped role; it does not override process.
No single actor or constituency is permitted to dominate epistemic outcomes.
Governance bodies govern process and admissibility — not conclusions.
Downstream use (markets, policy, advocacy) remains strictly external to governance.
