# ClassOne System 1 Decision Curriculum (23,503 Examples)

The **ClassOne System 1 Decision Curriculum** is a multi-domain, structured decision corpus designed to train and benchmark zero-generation **System 1 decision models**. Instead of generating free-form conversational text, models trained on this curriculum evaluate complex contexts (`state`) against typed questions (`noul`, `choice`, `score`) in a single forward pass, returning calibrated probabilities, categorical selections, and continuous rubric ratings.

This curriculum powered the state-of-the-art results for the ClassOne family on [JevBench](https://github.com/fstandhartinger/jevbench) (reaching **80.1%** on Qwen 3.5 9B and **70.1%** on Gemma 4 E4B) and [RLCDAlignBench](https://github.com/sumleo/RLCDAlignBench) (reaching **63.3% Balanced Accuracy**).

## Dataset Summary

- **Total Samples:** 23,503 fully structured decision items.
- **Decision Primitives Covered:**
  - **`Noul` (22,178 instances):** Binary policy compliance, factual verification, and security safety checks returning $P(\text{true}) \in [0, 1]$.
  - **`Choice` (19,030 instances):** Fine-grained categorical classification over 2–255 dynamic natural language criteria.
  - **`Score` (4,639 instances):** Continuous ordinal rubric ratings across 2–5 rubric levels (e.g. SEV-1 to SEV-4, urgency, impact).
- **Format:** Available in columnar Apache Parquet (`train.parquet`) and line-delimited JSONL (`train.jsonl`).

## Dataset Structure

Each sample is formatted with the following schema:

```json
{
  "sample_id": "classone_curriculum_00001",
  "state": "{\"reference_text\": \"The mRNA is divided into three-base segments called codons...\", \"question\": \"What is the total number of codons?\"}",
  "questions": {
    "choice_question": {
      "type": "choice",
      "instructions": "Select the correct factual answer:",
      "criteria": {
        "ans_64": "There are 64 codons in total",
        "ans_20": "There are 20 codons in total",
        "ans_3": "There are 3 codons in total"
      }
    },
    "has_evidence": {
      "type": "noul",
      "instructions": "Is explicit evidence for the number of codons present in the reference text?"
    }
  },
  "targets": {
    "choice_question": "ans_64",
    "has_evidence": 1
  },
