| batteryswap_public | 0.3.4 | https://pypi.org/project/batteryswap-public/ | Organizer package; PyPI metadata does not declare a license |

`batteryswap_public` is required by the official example and evaluation interface. Its PyPI metadata does not state a license. Obtain written organizer confirmation before the competition deadline.

The submission image is the organizer/example base
`huggingface/competitions@sha256:6cea4ff69a6832761484f48c07ccfbf49f701f285ffcb9fc72a4ecfb81b6b4e5`.
It contains the NVIDIA Deep Learning Container license notice even though this entry is
CPU-only. Because this is the official evaluator base rather than participant code, it is
recorded separately; obtain organizer confirmation together with `batteryswap_public` if
prize-eligibility review requires an explicit exception.
