vta-service 0.2.1

//! VTA (Verifiable Trust Agent) service library.
//!
//! This is the shared business logic used by both the `vta` binary
//! (local/dev/cloud) and the `vta-enclave` binary (Nitro Enclave).
//!
//! Front-end binaries import this library and call `server::run()`
//! with the appropriate store backend and TEE context.
