check / check (push) Waiting to run
cli.Main starts the server only when given no arguments. check-cidr CIDR and prepare-data-dir DATA_DIR run as before. Any other command line, such as a subcommand with no value or two values, or a misspelt subcommand, gets a one-line usage message naming both forms on stderr and exit code 2. It used to start the server, which then held the port. Model: opus-5-5
