# snowGAN release v0.1.0

Snapshot of a snowGAN training run, packaged for downstream consumers
(AvAI etc.). Consume with `snowgan.weights.fetch("RMDig/snowGAN-core", "v0.1.0")`.

## Artifacts
- `discriminator.weights.h5`
- `discriminator_config.json`
- `discriminator_lowres.weights.h5`
- `generator.weights.h5`
- `generator_config.json`
- `generator_ema.weights.h5`
- `generator_fade_endpoints.weights.h5`

## Notes
First core release. Trained ~127k steps without spectral_norm; disc loss diverged post-step-80k due to small dataset (~13 cores) + no Lipschitz constraint + unconstrained multiscale_disc lowres critic. Generator produces structured outputs (vertical snow-like patterns, blue/white palette). Backbone Conv3D features usable for transfer; full retrain with --spectral_norm planned for v0.2.0.
