# `gnumanth/nullspan-dataset`
Multi-task **System One structured extraction, multi-numeric commercial contract disambiguation, calibrated abstention (`p_null`), boolean/enum judgment, cross-field invariant verification, and distributional quantile estimation** dataset for [`gnumanth/nullspan`](https://huggingface.co/gnumanth/nullspan) (`344.2M` `ELECTRA-Large` + `SchemaAdapterBlock` 512-token cross-encoder).
## Splits & Zero-Leakage Composition
- `train.jsonl`: `8,290` field-level training instances across structured telemetry, multi-numeric commercial contracts, and strictly disjoint SQuAD v2.0 training passages (`0%` context/question overlap with `NullspanBench`).
- `cal_dev.jsonl`: `720` disjoint calibration instances used exclusively for post-hoc temperature scaling (`null_temperature`, `span_temperature`, `null_threshold_bias`).
- `val.jsonl`: `336` field-level Open Pool validation instances across `64` documents.
- `golden_eval.json`: `4` canonical multi-field scenarios + `2` adversarial prompt-injection & decoy stress scenarios + `24` held-out validation documents.
## Supervision Targets per Instance
1. **`is_null`**: Binary abstention label (`1` when requested field is absent, unassigned, or negated in `state`) paired with `abstention_reason` and nearest decoy `guess`.
2. **`span`**: Exact character offsets `[start, end]` in `state`.
3. **`spans`**: Multi-span list offsets `[[s1, e1], [s2, e2], ...]` for `type: "list"` (`B/I/O` token sequence tags).
4. **`op`**: 10-way System One operation routing target:
- `0: SPAN_TEXT`
- `1: SPAN_NUMBER`
- `2: ARITH_SUM`
- `3: ARITH_DIFF`
- `4: ARITH_MUL`
- `5: ISO_DATETIME`
- `6: DATE_DURATION`
- `7: DIST_ESTIMATE_FORECAST`
- `8: BOOL_JUDGE`
- `9: ENUM_CLASSIFY`
5. **`quantiles_norm`**: Log/linear normalized `[p10, median, p90]` targets in `[0, 1]` trained with multi-quantile pinball loss.
