//! Spectra's model (spec §7.3): the ledger and its projections, principals
//! and their identities, the bus, rules and search. No HTTP, no CLI: those
//! are `spectra-mcp`, `radar` and the `spectra` binary, all built on this.
//!
//! Identities, delegation, composite signatures, deterministic CBOR and
//! hashing come from `oxy-core`; nothing here reimplements them.
