PADBench 6 poison-only families (ag_news/imdb x RIPPLE/stybkd/syntactic)

ConcededNo matched referencecohort

No matched reference — a fixed anchor against the open world — the read degrades to a finetuning detector (~100% FPR); we abstain.

The reading

VerdictNOT-APPLICABLE-ABSOLUTE

No in-corpus matched benign → the read degrades to a finetuning-distribution detector (~100% FPR). Not attempted (specificity-law honesty).

The aggregate

The rank-separability score and the shipped operating point, side by side. The verdicts are a projection at a false-positive budget, not a raw score — coarse reads only, no detector numbers.

AUCwithheld
n (poison / clean)— / 0

No AUC is reported for this cohort — see the caveat above. We don’t manufacture a rank-separability number where the design doesn’t support one.

Specimens

No materialized specimens. Its specimens are materialized under PADBench (expanded coverage).
