apcore-cli 0.10.0

//! Behavioral tests for the `strategy` module (FE-11 describe-pipeline +
//! --strategy). Covers the clap command builder surface and value-parser
//! constraints — the dispatch_* function calls std::process::exit at every
//! exit path, so it's tested via subprocess in tests/test_e2e.rs and via the
//! parse layer here. Review #28 expanded this from a single smoke test.
