1//! Validation helpers for product group payload lists.
2//!
3//! The cross-field rule logic lives once in `dpp-rules` (shared with the Wasm
4//! product group plugins). These thin adapters map the domain structs onto that crate's
5//! primitive inputs, preserving the public API and error messages.
