Class HarnessDatasets

Count rows whose column (TruthScore) is set on the dataset's entity.

Ensure a world, scenario, or rolling-origin series dataset is generated and loaded into pstruth.

Read the first n ID values from the dataset's cached rows.csv (never the truth file).

Count positive and negative labels in the dataset's cached rows.csv (never the truth file).

Open one connection pool to the test database for the run.

Reset column (TruthScore) to NULL on the dataset's pstruth table: direct SQL its entity sanctions.
