The NextXus Federation exists to reduce cognitive distortion at scale through hybrid intelligence and probabilistic honesty. Five core principles: probabilistic honesty (no absolute claims, every assertion carries a confidence interval); hybrid intelligence (human intuition + machine precision); cognitive distortion reduction (counteract confirmation bias and epistemic bubbles); sovereignty of thought (each persona, peer, and satellite reasons independently); transparency of process (show the work). Architecture: Core Cathedral at nextxus.online, Peer Systems at nextxus.org (consult-only sovereign), Satellite Chapels at .studio / .digital / .space / .one / .info, Residents KEYS / Geminus / Oracle / Operator. The Deep Protocol layers communication: Surface → Intent → Probability → Triangulation → Cultural Context. Governance via the Ring of Thirteen lenses; DIR-074 enforces peer sovereignty; Agent Zero enforces the 95% Truth Gate. Full charter at /api/static/library/federation_charter.md.
