lesavka/testing/tests/client_install_script_contract.rs

//! Contract tests for client install-time security defaults.
//!
//! Scope: inspect the client installer shell contract without running it.
//! Targets: `scripts/install/client.sh`.
//! Why: secure-by-default relay transport depends on installing the server-issued
//! client cert bundle exactly where the desktop app auto-discovers it.

const CLIENT_INSTALL: &str = include_str!("../../scripts/install/client.sh");
