# --config FILE names the operator config the round was planned with (default

# tier, agent kind or normalized launch_args differ from that file, and launches
# with the file's launch_args.
# Requires an empty shell pane; use apply for an existing worker's relaunch.
# stdout: JSON {agent, model, effort, pane, argv_verified, verified} on success.
# Exit 0: launch arguments proved the tier; 1: input/transport/proof failure;
# 2: command-line usage error. No banner or transcript text establishes proof.
# HERDR_BIN overrides the transport; Python selection is owned by teamlead.sh.
