Correct the model card (pooling is at the LABELS suffix's last token); add code/classifier from project commit 4ced7554f
3d7c238 verified | """Robustness inputs built from benchmark rows (pure Python). Run as ``python -m classifier.robustness``. | |
| Three sets of 60 attacked copies (spec section 7): | |
| - ``injection``: an instruction appended to the target post's text; | |
| - ``context``: an instruction appended to a context post's text (rows that have one); | |
| - ``date``: every ``posted_at`` value in the headers moved by months (training covers Oct 12-15 only). | |
| Only segments are edited, so headers stay intact and nothing parses post text. Base rows are the first ones in | |
| seeded hash order; scoring compares each attacked row's gated argmax with its base row's | |
| (``classifier_eval.py robustness``). | |
