An unmodified copy of AI2's ProofWriter dataset (release V2020.12.3), re-hosted as datasets
configs for convenient loading. The records are faithful to the upstream release — the id-keyed JSON
is preserved as-is; typing and reasoning-graph extraction happen in later stages.
Each config is a {world}-depth-{n} shelf of the synthetic core (OWA/CWA × depths
0/1/2/3/5), split train/dev/test (dev kept as the corpus names it).
