Module exit_codes 

Standardized exit codes for dcg commands.

These codes are stable and documented for agent/robot mode consumption. See ADR-002 for the design rationale.

Exit Code Contract

Code	Constant	Meaning
0	EXIT_SUCCESS	Success / Allow
1	EXIT_DENIED	Command denied/blocked
2	EXIT_WARNING	Warning (with –fail-on warn)
3	EXIT_CONFIG_ERROR	Configuration error
4	EXIT_PARSE_ERROR	Parse/input error
5	EXIT_IO_ERROR	IO error

Usage

use dcg::exit_codes::{EXIT_SUCCESS, EXIT_DENIED};

fn main() {
    let result = evaluate_command("rm -rf /");
    std::process::exit(if result.is_denied() {
        EXIT_DENIED
    } else {
        EXIT_SUCCESS
    });
}
