# FrontierChallenge

FrontierChallenge provides **97 scientific workflow tasks** with plaintext
English instructions, inputs, Harbor definitions, domain labels, and the
redistributable open runtime image.

| Path | Contents |
|---|---|
| `manifest.jsonl` | Dataset Viewer rows with task ID, taxonomy, difficulty, runtime, and instruction |
| `tasks/<task-id>/` | `instruction.md`, task metadata, environment definition, and agent-visible inputs |
| `images/` | Verified `linux/amd64` Docker archive for the 81 open-image tasks |

This repository contains no graders, rubrics, fixtures, or reference outputs.
Those are stored as encrypted archives in the separate
[`apodex/FrontierChallenge-reference`](https://huggingface.co/datasets/apodex/FrontierChallenge-reference)
dataset.

Use the [FrontierChallenge runtime](https://github.com/ApodexAI/FrontierAgent/tree/main/benchmarks/frontierchallenge)
to download both datasets, verify their shared registry, load the image archive,
run Harbor, and score a task. The evaluator host needs Python 3.12+ for the
pinned Harbor 0.20.0; task containers keep their own frozen Python versions.

```bash
git clone https://github.com/ApodexAI/FrontierAgent.git
cd FrontierAgent/benchmarks/frontierchallenge
python3.12 -m venv .venv
source .venv/bin/activate
python -m pip install -e .
HF_TOKEN=hf_... ./scripts/setup.sh --track open
cp .env.example .env
# Fill model and judge credentials in .env before running.
./scripts/run_eval.sh \
  --agent claude-code --model <model> \
  --include-task-name task_011_cell_migration_wound_healing
```

The 16 task definitions that execute ORCA and their inputs are included
normally. ORCA itself and an ORCA-configured image are never distributed;
evaluators obtain ORCA from its official provider and follow the runtime
repository's [local-image tutorial](https://github.com/ApodexAI/FrontierAgent/blob/main/benchmarks/frontierchallenge/docs/providers/orca.md).

Track membership follows what a task executes, not software named in supplied
files. For example, `task_098_orca_claisen_thermochemistry` reads precomputed
ORCA output without running ORCA, so it remains in the open track.

Verify a downloaded solve package with:

```bash
python tools/verify_dataset.py
```

## Metrics

Official Pass Rate uses a **strict score threshold**: a task passes only when
`evaluation_complete == 1` and valid `task_score > 0.999`. Native per-task
thresholds do not determine this metric.
Use unrounded scores: exactly `0.999` does not pass; `0.9991` and `1.0` pass.

- **Pass Rate (%)** = 100 × number of completed tasks with valid `task_score > 0.999` / 97.
- **Score (0–100)** = 100 × sum of valid, completed `task_score` values / 97.
- Partial credit remains the native rubric score normalized to [0, 1].
  Missing tasks, invalid scores, and incomplete evaluations contribute zero
  to the fixed denominator and must be reported separately; incomplete runs
  are not final benchmark results.
- Use one predeclared attempt per task. A subset may use its predeclared task
  count as denominator, but must be labeled as a subset, not the 97-task result.

There is only one pass field, `passed`, using the same strict threshold in
`reward.json`, `summary.csv`, and `summary.json`. No alternate pass field is
emitted. The runtime applies this rule to the staged reward adapter after
unsealing; encrypted archives and partial-credit rubrics remain unchanged.
The updated runtime also removes native pass decisions from published verifier
diagnostics. Jobs created by older runtimes cannot be resumed under the new
policy: use a fresh job name. Old files are left untouched; summarizing an old
job recomputes the official metric but does not rewrite its logs or rewards.
The summary records `metric_definition: score-gt-0.999`. Historical results
using per-task thresholds, `== 1.0`, or `>= 0.999` must be recomputed from raw
scores before comparison. See the
[scoring guide](https://github.com/ApodexAI/FrontierAgent/blob/main/benchmarks/frontierchallenge/docs/scoring.md)
and [runtime update](https://github.com/ApodexAI/FrontierAgent/pull/30).

**Runtime rollout:** the runtime update is pending. Before reporting results,
check that your summary records `metric_definition: score-gt-0.999`;
older runtimes use the legacy rule. Use the runtime summary for the fixed
97-task denominator; Harbor may aggregate only attempted trials.

## Integrity

The root `README.md` is a mutable dataset card and is intentionally outside
`checksums.sha256`. Task files (including task-level READMEs), manifests,
registries, and verification tools remain checksummed. Payload changes require
regenerating their checksum entries; editing this card does not.
