Each session's metadata.yaml contains its instruction, preference, long-form feedback, timestamps, and per-policy outcome fields. The top-level global_metadata.yaml contains aggregate counts and a policy index with open-source and action-space annotations.

Policy names are preserved exactly inside metadata. For portable directory names, characters outside letters, numbers, ., _, and - are replaced by underscores. For example, allenai/MolmoAct2-DROID is stored under a directory component named allenai_MolmoAct2-DROID.
