uor-addr 0.2.0

UOR-ADDR — the typed reference vocabulary for content-addressing across recursively-grammared formats. Standard-library Layer-3 Prism realization of the UOR Foundation; ships the common architectural surface plus the JSON realization under JCS-RFC8785 + NFC + SHA-256.

//! Per-realization σ-axis wiring macros.
//!
//! Every realization is identical except for its canonical-form input
//! carrier: the ψ-tower, the bounds, and the resolver tower are shared,
//! and the κ-derivation verb body is the same four-ψ composition
//! (`k_invariants ∘ homotopy_groups ∘ postnikov_tower ∘ nerve`). The only
//! per-σ-axis variation is the bound `H`, the per-axis output shape, and
//! the κ-label byte width.
//!
//! foundation 0.5.1's resolver tower admits only `Hasher<32>` axes, so a
//! realization wires the four 32-byte axes ([`crate::hash`]). These macros
//! emit the four per-axis verbs ([`addr_verbs!`]) and the four per-axis
//! [`PrismModel`](prism::pipeline::PrismModel) declarations
//! ([`addr_models!`]) from a single per-realization invocation, keeping the
//! per-realization source to the carrier handle + the public entry points.

/// Emit one κ-derivation `verb!` per σ-axis. `input` is the carrier type as
/// it appears in a `verb!` signature (e.g. `JsonCarrier<'_>` or
/// `RingElement`); each `{ shape, verb }` names the axis's output shape and
/// the generated verb function.
