# MATTER-604 Public Questions

MATTER-604 evaluates materials-science Agents on structure construction and
retrieval, scientific analysis, workflow orchestration, input generation,
data diagnosis, execution contracts, batch processing, and safety refusal.

This repository contains the 604 public task prompts and declared input
fixtures. It intentionally does **not** contain per-task reference answers,
checklists, Gold thresholds, or the private evaluator. Submit answers and task
artifacts through the benchmark evaluation service.

## Splits

`data/test.jsonl` contains the 604 evaluation questions. The test labels are
private. `fixtures/` contains only local files explicitly declared by a task's
`data_files` field.

Six declared inputs are not copied into this repository: two VASP POTCAR files
and four third-party publisher PDFs. Their records use
`distribution=restricted` and provide the exact SHA-256 plus lawful acquisition
instructions. A runner must provision those files outside the dataset repo and
verify their hashes before starting the affected task.

## Scoring method

Each private checklist item receives a binary pass/fail verdict and an optional
weight. Within each active axis:

`axis_score = sum(pass_i * item_weight_i) / sum(item_weight_i)`

The overall score is the weighted mean of active correctness, grounding, and
efficiency axes. Exact per-task criteria, expected values, tolerances, and
Gold files remain private to prevent direct answer lookup.

## Intended use and contamination policy

Use this dataset for evaluation, not training or answer distillation. Public
availability cannot technically prevent training; benchmark users should
disclose any exposure to MATTER questions or model answers. The official score
is produced only by the versioned private evaluator identified in
`private_eval_commitment.json`.

## Runtime

The closed-source MatMaster image is not distributed. Third-party Agents may
use their own runtime as long as they receive only the public task package and
return the documented answer/artifact bundle.
