# INSTRUCTIONS
# ------------
# From dist_agent_lang:
#   ./scripts/mutation_testing/run_from_terminal.sh
# From repo root:
#   cd dist_agent_lang && ./scripts/mutation_testing/run_from_terminal.sh
#
# Test suite:
#   MUTATION_TEST_SUITE=lib   -> --lib only (faster)
#   MUTATION_TEST_SUITE=tests -> --tests (default; runs tests/*.rs, catches more)
#
# Scoped runs (see run_with_tmux.sh for the same variables):
#   MUTATION_FILE=src/cli.rs ./scripts/mutation_testing/run_from_terminal.sh
