# EngIntervene

**Input release approved by the release maintainer. This repository contains all 3,229 items and 2,275 referenced input assets; scoring references are kept separately.**

EngIntervene evaluates industrial visual understanding, relation modeling, diagnosis and reasoning about design changes. This anonymous-format copy contains all **3,229** items from the frozen benchmark; it is not a new collection and does not change the reference answers or scoring weights.

## Tasks and coverage

| Task | Capability | Items | Expected response |
|---|---|---:|---|
| T1 Understand | Visual component and engineering-symbol understanding | 2,149 | Correct option ID(s) |
| T2 Model Relations | Entity, connection, path and mechanism reasoning | 420 | Answer and engineering relations |
| T3 Diagnose | Localizing and explaining issues and violated constraints | 420 | Diagnosis and supporting explanation |
| T4 Reason about Changes | Evaluating/proposing revisions and checking protected conditions | 240 | Revision, effect/mechanism and constraint reasoning |

| Stored domain ID | Domain | Items |
|---|---|---:|
| `mechanical_industrial` | Mechanical Design, Manufacturing and Industrial Equipment | 505 |
| `robotics_mechatronics` | Robotics and Mechatronics | 456 |
| `automotive_integration` | Automotive System Integration | 450 |
| `aerospace_integration` | Aerospace Integration and Reliability | 454 |
| `building_mep` | Building Services and MEP Systems | 460 |
| `energy_equipment` | Power and Energy Equipment | 454 |
| `compact_electronics` | Compact Electronics Packaging | 450 |

The single `test` split in this export means **the complete 3,229-item evaluation corpus**. It is not a training/adaptation split and is not just a historical challenge subset. No source-grouped train/validation/test experiment partition is invented by this export.

## Loading locally

```python
from datasets import load_dataset

dataset = load_dataset(
    "parquet",
    data_files={"test": "data/test-*.parquet"},
    split="test",
)
example = dataset[0]
images = example["images"]  # list of decoded PIL images
prompt = example["prompt"]
```

Run this snippet from the dataset directory, or use the included `load_benchmark.py` helper. You can also load the Hub version as follows. If repository visibility is private, first authenticate an account with access using `hf auth login`.

```python
dataset = load_dataset("benchmarkanon/EngIntervene", split="test")
```

No credentials, private author identity or server paths are included in this repository.

## Format

- `data/*.parquet`: typed records with embedded image bytes. Images are a variable-length `List(Image)`; their stored names are neutral basenames, never host filesystem paths.
- `metadata/questions.jsonl`: matching text-only records and image IDs; image bytes remain in Parquet. This file alone is not the full multimodal input.
- `metadata/auxiliary_inputs.jsonl`: original structured `context` / `candidate_revisions` fields, where present, joined by `item_id`. They are preserved as question-side auxiliary data; the historical evaluation prompt did not automatically append these fields.
- `metadata/assets.jsonl`: image IDs, dimensions, pixel/file checksums, source links by ID and effective publication flags. Earlier source-metadata flags are retained in a separate historical field.
- `PUBLICATION_STATUS.json`: anonymous maintainer publication decision and affected asset IDs.
- `metadata/sources.jsonl`: third-party attribution and existing source-license metadata. Source institutions are not benchmark-author affiliations.
- `schema.json`: the Hugging Face feature schema.
- `NOTICE.md`: publication decision, source-attribution information and license-status distinctions; no blanket license is assigned by this update.

The typed columns include `item_id`, `task`, `domain`, `subtask`, `system_family`, `question`, `choices`, `response_contract`, `prompt`, `image_ids`, `images`, `source_id`, `adaptation_type` and `redistribution_status`.

The `prompt` field reproduces the existing task-level evaluation template, after any necessary identity redaction. It contains the benchmark question, options and response requirements; it does not include OCR archives, source-document excerpts, private labels, rubrics or backend-specific system prompts. Preserve all images and option IDs. T1 expects `{"choice_ids":["<original option ID>"]}`; T2–T4 expect `{"answer":"..."}`.

For comparison with existing runs, use `prompt` and all corresponding images. Adding auxiliary context, revision fields or other metadata to a model's input changes the evaluated input protocol and should be reported explicitly, rather than silently treated as the same baseline.

## References and scoring

Gold references and rubrics are in a **separate local scoring package**, not in this input repository. A folder name such as `private_scoring` is not access control: never put the scoring package into a public input repository by mistake.

T1 uses exact option-ID/set matching. T2–T4 use the stored weighted rubric with applicable critical-error handling. T4 has two distinct metrics: partial-credit Atomic Rubric Score and Strict Revision Success. Preserve both. Changing an evaluator or a judge requires an explicit evaluation protocol; this packaging step runs no model and reports no new scores.

## Anonymity and limitations

Private builder/reviewer identity fields, local account paths, build timestamps, infrastructure details, logs, credentials and repository history are excluded from the package. Image metadata is removed while preserving displayed pixels; images are not redrawn, cropped or anonymized by inventing content. Automated Chinese/English OCR and targeted inspection are used to screen disclosed identity strings. This does not prove that every unreadable, stylized or undisclosed identifier is absent.

Third-party source attribution remains. Do not erase source copyright notices to imply ownership. Source-language metadata is not a label for the normalized model-input language. Incomplete visual/relation taxonomy and unresolved semantic rubric issues are not silently relabeled by this release preparation.

Examples may contain other questions or source markings from original examination pages. The export preserves the current evaluated visual content. The benchmark mixes source-normalized, source-adapted and source-supported constructed questions; none of these terms means that every question is an untouched original examination question.

## Format references

This export follows the documented [Hugging Face image/Parquet representation](https://huggingface.co/docs/hub/datasets-image) and [dataset-card structure](https://huggingface.co/docs/hub/datasets-cards). Format compatibility is not approval to redistribute source content.

## Publication decision

The effective `redistribution_status` is `approved_for_public_release_by_maintainer` for every item. All referenced input assets have `redistribution_allowed=true`. This records the maintainer's explicit decision; it does not claim newly verified third-party permissions. Historical source flags and source-license metadata remain available. See `PUBLICATION_STATUS.json` and `NOTICE.md`.
