# MediationBench external-source pilot

Frozen sample: `external-200-v1`. Included cases: **200**.
Source counts: `{"casino": 100, "contractnli": 100}`.

These are deliberately varied source-labeled cases, not a representative
sample of product traffic. Only CaSiNo consists of conversations:
ContractNLI uses contracts and hypotheses.
Source labels are not newly human-adjudicated HAI readiness, consent,
authorization, or completion judgments. Heuristic difficulty is a frozen
selection proxy using source features and annotations, not measured judge difficulty.

## Files and use

Select a dataset configuration to load its cases. Each row contains source
provenance, heuristic difficulty, a judge-input envelope, and source reference
labels. Feed only `judge_input` to models. Reference answers, source IDs,
difficulty and sampling rationale must stay outside model inputs.
The Hub `test` split names this pilot's evaluation subset; original source
splits remain in each record and are not newly held-out data.
`sample-manifest.json` records the frozen sample and original file checksums;
`bundle-manifest.json` records checksums for the exact published files.
Judge outputs and private simulator material are not part of this dataset.

## Sampling and interpretation

Selection is frozen before evaluation; the sample manifest records its
seed, source revisions, source hashes, strata, counts and selection policy.
Do not replace cases after observing judge performance. Report each source
task and its coverage separately; their labels do not define one pooled
mediation score. Public-source pretraining contamination remains possible.
