The public release ships the frozen 674-task corpus in ``data/tasks_674.jsonl``.
The split builders import this module for the canonical path, checksum, and a
streaming SHA-256 implementation; generation inputs such as Beam/BFS result
files remain optional research artifacts and are not required for evaluation.
