ralph-agent-loop 0.3.1

//! Parse-regression tests for the top-level CLI surface.
//!
//! Responsibilities:
//! - Verify key top-level command routes and rejected legacy flags.
//! - Keep root CLI parsing coverage out of the root facade file.
//! - Assert version/help behaviors exposed by Clap.
//!
//! Not handled here:
//! - Exhaustive per-subcommand argument validation owned by submodules.
//! - Runtime execution behavior after parsing succeeds.
//!
//! Invariants/assumptions:
//! - Tests exercise the public `Cli` parser exactly as end users invoke it.
//! - Removed flags/subcommands must remain rejected.
