# CausalGame - OpenCode Agent Runner
#
# Supports concurrent experiments via Docker Compose project isolation.
# Same experiment can have multiple models running against one game-backend.
# Different experiments get separate game-backends automatically.
#
# Usage:
#   ./run_opencode.sh -m openrouter/moonshotai/kimi-k2.5                    # Start
#   ./run_opencode.sh -m openrouter/moonshotai/kimi-k2.5 --run              # Start + run
#   ./run_opencode.sh -m openrouter/moonshotai/kimi-k2.5 --watch            # Watch thoughts
#   ./run_opencode.sh -e antenna_trap --down                                 # Stop experiment
#   ./run_opencode.sh --down-all                                             # Stop everything
#
# Concurrent example:
#   ./run_opencode.sh -e antenna_trap -m openrouter/moonshotai/kimi-k2.5     # Experiment A, Model 1
#   ./run_opencode.sh -e antenna_trap -m openai/gpt-5.2                      # Experiment A, Model 2 (shares backend)
#   ./run_opencode.sh -e weather_defense -m openai/gpt-5.2                   # Experiment B (separate backend)
