# Compose-only validation of every arm's Hydra override list, in the real container.
#
# WHY THIS EXISTS. On 2026-08-20 all four arms were config-valid, schema-valid and diffed cleanly
# against each other, and the first link still died 12 minutes in on
# hydra.errors.ConfigCompositionException: Could not append to config.
# An item is already at 'terminal_bench_config.trace_upload.enabled'.
# A config that parses is not a config that composes, and an arm-vs-arm diff cannot catch a fault
# that every arm shares. This runs the launcher's real dry-run, extracts the real override list,
# and composes it against the real ppo_base_config inside the real container -- with no GPUs, no
# Ray, and no allocation. Run it after any config change and after any SkyRL sync, before
# submitting anything.
#
# Prints one line per arm. Anything other than COMPOSE OK on all four is a stop.
