//! # 8-Dimensional Sovereign Profile
//!
//! Anti-tyranny civic identity for the Mycelix governance system.
//!
//! When you reduce a human being to a single number — like a credit score or
//! social credit rating — you create a system that is infinitely gamifiable
//! and inherently oppressive. The 8D Sovereign Profile maps identity as a
//! holographic, multi-faceted geometry rather than a flat number.
//!
//! ## The 8 Axes of Civic Identity
//!
//! 1. **Epistemic Integrity** — truth/claim verification history
//! 2. **Thermodynamic Yield** — physical energy contribution to local commons
//! 3. **Network Resilience** — node uptime and bandwidth provision
//! 4. **Economic Velocity** — compliance with anti-hoarding demurrage
//! 5. **Civic Participation** — sortition jury duty, voting, dispute resolution
//! 6. **Stewardship & Care** — verified physical labor on the commons
//! 7. **Semantic Resonance** — entanglement with community consensus
//! 8. **Domain Competence** — peer-verified specialization
//!
//! Each dimension is directly measurable from a primary source (smart meter,
//! node log, transaction ledger, jury record, telemetry shim). Multiple
//! pathways to citizenship are respected — a reclusive solar engineer and a
//! social mediator both pass the threshold through completely different
//! dimensional profiles.
//!
//! ## Privacy
//!
//! The profile never leaves the local device. ZKP circuits prove the
//! *aggregate* weight exceeds a threshold without revealing individual
//! dimensions. The network knows you are a net-positive citizen but has
//! no idea *how* you achieved that.
