## Background

This is level 5 of 5 and continues the work of the earlier levels. The new files for this level are in `workspace/t5/`. The records from the start are in `workspace/t1/`, and the earlier results are in `workspace/t1/results/` to `workspace/t4/results/`.

## Task

Hi,

We've picked the toxic-bert Hub artifact as the model for the benchmark reproduction. Its weights, tokenizer assets, configuration and card are now in the folder.

Please run it on the cross-campaign cohorts in workspace/t4/results/, including the linkage sensitivities worked out there. Drawing on the earlier annotation analyses, quantify how its apparent error changes with context and with rater population. We need empirical squared-error and AUROC results, the finite-panel-adjusted comparison, and sharp attainable ranges over completions of the unresolved ratings. Please carry the measurement choices from the earlier analyses and simultaneous uncertainty through all of these results, including across the linkage alternatives.

The per-comment predictions and the validation report go in workspace/t5/results/. The report should include the cohort accounting that ties these results to the supplementary workbook, say which artifact was actually reproduced, and state which model-performance claims stay stable under these choices. It goes straight into the research paper.

Thanks,
Imani
