	fs::write(out_path, code).with_context(|| {
	format!("Failed to write generated client to {}", out_path.display())
	})?;

fs::write(out_path, code) is non-atomic. If the process is interrupted (SIGKILL/OOM/Ctrl-C) mid-write, out_path is left truncated/empty, silently corrupting a committed generated client.

Fix: write to a temp file and fs::rename into place.
