The model’s verdict
The Transformer retrained from the notebook (the 2024 weights were never saved), shown three ways. The first is how the notebook evaluated it.

Retrieved vs gold evidence
Gold passages were picked by the dataset’s annotators. Retrieved passages are what the TF-IDF rule returned from all 1.19M passages. Switch between the submitted 2024 output and the re-runs.
2024 submission
The passages the team actually retrieved and submitted in 2024 (their saved output file). The file records only passage ids, so scores are recomputed with the submission rule.
