 The full dataset is never inferred from a moving branch. Builders must check out
 ``globalwordnet/english-wordnet`` at the exact release tag and commit declared
 below, then pass the ``src/yaml`` directory to :func:`load_oewn_2025`.

+Sense order is source evidence. The loader therefore preserves the order of the
+OEWN ``sense`` list exactly rather than sorting senses by identifier.
