# Chorus mirror: LegNet small (chorus-pinned)

Mirror of `chorus_small_legnet.zip` originally hosted at
`https://zenodo.org/records/17863550`. The Zenodo record is chorus-pinned;
this HF mirror is for consolidation alongside the other chorus oracle
mirrors.

## Source

- Original: Zenodo record [17863550](https://zenodo.org/records/17863550)
  (chorus-published bundle).
- Underlying model: LegNet (Penzar et al. 2023, *LegNet: A best-in-class
  deep learning model for short DNA regulatory regions*, Bioinformatics 39).
  https://doi.org/10.1093/bioinformatics/btad457
- Reference repo: https://github.com/autosome-ru/LegNet

## License & attribution

The bundled weights are derivatives of the LegNet checkpoints released
by the Autosome.ru / VIGG team. Those checkpoints were created by the
LegNet authors and remain their property.

The model parameters, outputs, and any derivatives thereof remain subject
to the original LegNet license (**CC BY 4.0** per the upstream repository).

The chorus-published bundling (config + LentiMPRA HepG2/WTC11 selection)
and loader code are released under the chorus license. These terms are
consistent with the terms for the reference code and the model weights.

## Contents

`chorus_small_legnet.zip` — the chorus-bundled small LegNet checkpoints
for LentiMPRA (HepG2 + WTC11). Byte-identical to the Zenodo record.

## Usage

In chorus ≥ 0.4 the `LegNetOracle` fetches from this HF repo by default
and falls back to Zenodo if HF is unreachable.
