//! Outcome to CLI boundary mapping (EE-009).
//!
//! Maps Asupersync's `Outcome<T, E>` to CLI exit codes and error responses.
//!
//! # Outcome Severity Lattice
//!
//! Asupersync defines a severity lattice where worse outcomes dominate:
//! `Ok < Err < Cancelled < Panicked`
//!
//! This module maps that lattice to CLI exit codes:
//! - `Ok(T)` → exit 0 (success)
//! - `Err(DomainError)` → exit 1-8 (domain-specific errors)
//! - `Cancelled` → exit 130 (SIGINT convention)
//! - `Panicked` → exit 101 (Rust panic convention)
//!
//! # Usage
//!
//! ```ignore
//! use ee::core::outcome::{CliOutcome, outcome_exit_code};
//! use asupersync::Outcome;
//!
//! let outcome: Outcome<(), DomainError> = Outcome::ok(());
//! let exit_code = outcome_exit_code(&outcome);
//! ```
