1 //! Non-interactive exec agent assembly: the `run_exec_agent` pipeline
2 //! that resolves the CLI route, builds the engine configuration, spawns
3 //! the engine, and drives the exec output stream to completion.
4 //!
5 //! Extracted verbatim from `lib.rs` (#5586, the issue's prescribed
6 //! engine-config-assembly cut). The two functions were crate-private in
7 //! the root and are `pub(crate)` here purely so the root's glob re-export
8 //! keeps the dispatch site and tests resolving unchanged.
