# DeepScaleR — Verifiable, Deduplicated

**37,713 questions. Only parser-compatible references are included.** Here, “verifiable” means every reference component parses with Math-Verify 0.8.0, with string fallback disabled. It does not mean that the answer has been independently proved correct or that grading model outputs is error-free.

DeepScaleR was processed independently: clean its questions, deduplicate within DeepScaleR, screen benchmark overlap and prompt leakage, then retain parser-compatible references. Shared questions with Skywork remain in this dataset.

## Preparation

See [PREPARATION.md](PREPARATION.md) for normalization, duplicate thresholds, conflict handling, benchmark screening, parser filtering, and limitations. [The complete preparation and publication code](https://github.com/Moe-Zbeeb/staleness-analysis/tree/95f55c5e518588771db8d761879f306ae01465c2/experiments/exact-age-14b-data) is pinned to Git commit `95f55c5e518588771db8d761879f306ae01465c2`. `manifest.json` records counts and checksums; `source-revisions.json` pins the upstream snapshots.

Only this filtered training pool is published. Raw inputs, rejected examples, benchmark questions, unfiltered pools, and models are not included.

## Loading

```python
from datasets import load_dataset

data = load_dataset("zbeeb/DeepScaleR-Verifiable-Dedup", split="train")
```

The `train` split names the complete released pool; it is not a precomputed train/validation partition. Split by shared question groups across datasets before comparing experiments.

## Schema

- `id`: SHA-256 of the representative normalized prompt.
- `prompt`, `messages`: original representative question and its single user message.
- `answers`: ordered reference components; do not assume these are alternative accepted answers.
- `reference_answer_raw`: original source reference serialized as JSON.
- `datasets`, `source`, `source_records`: memberships and provenance; `source_records` is serialized as JSON.
- `verifiability`: parser-compatibility flags; independent label verification is false.

Separate reference solutions are not appended to prompts. Explicit answer/solution section markers trigger conservative exclusion. Native model chat templates, generated responses, rewards, and reasoning-length restrictions are not embedded in this dataset.
