//! Explicit adapters for required external Candid interfaces, never owned Wire RPC.
//!
//! Select `candid-endpoint`, supply artifact-owned argument limits and the explicit
//! empty-envelope policy, and retain caller admission/authentication guards. The
//! adapters delegate entrypoints, async contexts and replies to the existing
//! generator/executor. Invalid arguments and encoding failures trap; access guards
//! retain their ordered rejection semantics. No parser or retry owner is added.
//! The unresolved Wasm nesting limitation in issue #73 remains applicable.
