abstract: >-
  A small, deterministic corpus of Parquet datasets observed at two or more
  versions, with machine-checked manifests recording the complete structural
  difference between versions and row- and value-level facts that hold across
  each transition. It records objective facts, not compatibility policy, for
  use as test input by ingestion frameworks, dataframe libraries, query
  engines, schema registries and data-contract tools.
