- Added empty string docstring column as placeholder
- Ensures compatibility when training across all prover datasets
- Real docstrings to be extracted and added in future update
- Prevents training errors from schema mismatch
This dataset had 3.4% docstring coverage, which is below the 5%
minimum threshold for retaining the column. Sparse docstring columns
(<5% populated) provide insufficient signal for ML training while adding
schema complexity and storage overhead. The column has been removed to
maintain data quality standards across the theorem prover dataset collection.
