1//! Molpha DataUpdate aggregate-Schnorr verification.
2//!
3//! A framework-agnostic library (no Anchor / Pinocchio dependency): the downstream program owns the
4//! registry account types and reads them, then passes plain data in. Verify a Molpha [`DataUpdate`]
5//! either from already-resolved signer pubkeys ([`verify_data_update`]) or from parsed registry
6//! entries plus a [`RegistryView`] ([`verify_data_update_resolved`]).
7//!
8//! # Usage
9//! ```ignore
10//! use molpha_verifier::{verify_data_update, DataUpdate};
11//!
12//! // `ordered_signers` are the signing nodes' (x, y) pubkeys in ascending signers_bitmap bit order.
13//! verify_data_update(&payload, node_count, redundancy_buffer, &ordered_signers)?;
14//! ```
