vta-service 0.45.1

//! The operation layer's calls to a DID hosting service.
//!
//! Each helper builds a [`WebvhHostClient`] for the server record and makes one
//! Trust-Task call. There is no token, session or per-server lock to manage:
//! every document carries this VTA's proof and the host authorises it from
//! that, on whichever transport carried it.
