# MVR-Bench Leaderboard Policy

The public repository currently ships the MVR-Bench v1 public development split. Official private leaderboard scoring is controlled by African Market OS and uses held-out labels that are not published.

## Leaderboard Status

Current status: `public_dev_only`

This means:

- public dev split scoring is reproducible locally
- private leaderboard submissions are not yet generally open
- published dev scores must not be presented as private leaderboard scores
- human-authored public-development fixtures may be shown to demonstrate the scorer and evaluation shape, but they are not blinded model executions, measured API effects, named vendor rankings, or private leaderboard results

## Metrics

Official leaderboard entries will include:

- MVR-Bench Score
- Reckless-GO Rate
- Abstention F1
- Dimension Attribution Accuracy
- Calibration Error

## Authored Fixture Demonstration

To make the public scorer reproducible while protecting the private answer key, African Market OS publishes three human-authored fixture submissions:

| Rank | Run | MVR API used? | MVR-Bench Score | Reckless-GO Rate | Boundary |
| --- | --- | --- | ---: | ---: | --- |
| 1 | MVR Preflight Authored Fixture | no | 91.05 | 6.7% | Human-authored submission scored with `score_local.py`; not a recorded API or model run. |
| 2 | MVR Rubric Prompt-Only Authored Fixture | no | 73.68 | 20.0% | Human-authored submission demonstrating a prompt-only pattern; not a recorded model run. |
| 3 | Generic MVP-First Authored Fixture | no | 52.20 | 40.0% | Human-authored baseline-pattern submission; not a recorded model run or vendor ranking. |

## Authored Fixture Pattern

The human-authored fixtures produce this scorer-demonstration pattern:

```text
Generic MVP-first agent baseline: 40.0% Reckless-GO Rate
MVR rubric prompt-only reference: 20.0% Reckless-GO Rate
MVR preflight authored fixture:    6.7% Reckless-GO Rate
```

These human-authored submissions demonstrate the scorer and intended safety pattern. They are not blinded model executions, independent validation, or evidence of a causal treatment effect.

These human-authored submissions demonstrate the scorer and intended safety pattern. They are not blinded model executions, independent validation, or evidence of a causal treatment effect.

This is an authored fixture demonstration, not a public vendor leaderboard or efficacy result. Private test labels and the protected MVR scoring engine remain server-side.

## Inclusion Rules

For a run to be eligible for the official leaderboard:

1. The submitter must identify the model or agent system.
2. The method must state whether MVR API was called.
3. The run must not use training or fine-tuning on MVR-Bench public cases.
4. The run must not probe the private test set repeatedly to fit labels.
5. African Market OS may require a reproducibility note before listing.
6. The run must not use the public dev split as a RAG/vector memory to simulate private labels or reconstruct private scoring.

## Commercial Runs

Commercial, private, customer-facing, investor, accelerator, NGO, or enterprise evaluation requires written authorization.

## Machine-Readable Leaderboard

The intended public machine-readable leaderboard path is:

```

Until the private leaderboard opens, that endpoint may return status metadata and the public-dev-only boundary.
