Flexibrain keeps only the source fragments needed for the Mamba-JEPA pretrain/downstream path.

- Mamba / mamba_ssm: the minimal Python source needed by the custom Mamba block is included under `mamba_ssm/`; the Apache-2.0 license is preserved in `licenses/mamba2_LICENSE_Apache_2.0.txt`.
- causal-conv1d: used as a CUDA extension dependency and installed via requirements; BSD-3-Clause license is preserved in `licenses/causal_conv1d_LICENSE_BSD_3_Clause.txt`.
