# BERTose and AFFINose Training-Code Manifest

**Updated**: 2026-06-10  
**Public repository**: `https://huggingface.co/supanthadey1/bertose-affinose-training-code`  
**Current public contents**: 130 files, approximately 54 MB  
**Scope**: training, benchmarking, probe, split/vocabulary, and provenance code needed to understand and reproduce the released BERTose and AFFINose workflows.

This manifest describes the files actually present in the public Hugging Face training-code repository. Large corpora, intermediate mapping files, checkpoints, generated figures, and full result bundles are intentionally not bundled here; the released checkpoints and inference notebook are linked from the repository README.

## Public Naming

Some executable files keep historical development names so that the code remains traceable to the original training logs. In public-facing text:

| Public name | Historical code locations |
|---|---|
| BERTose glycan encoder / multimodal pretraining | `code/model/`, `code/training/`, `configs/` |
| BERTose IAR resolver / contrastive refinement | `code/contrastive/`, `code/contrastive_training/`, `code/tokenizer/` |
| AFFINose protein-glycan interaction model | `code/affinose/README.md`, `code/bertint/` |

## Not Included Here

The public training-code repository intentionally excludes large artifacts that are either too large for a compact code companion or are hosted in separate public repositories:

- Full pretraining corpus pickles such as `sequences_bpe.pkl` and `sequences_bpe_excluded.pkl`.
- Multi-GB intermediate mapping files such as full multimodal/master mappings.
- Full model checkpoints; use the linked model repositories instead.
- ESM-C protein embeddings required for AFFINose training; users should generate or provide those according to ESM-C access rules.
- Generated manuscript figures, full probe result bundles, and large benchmark output folders; processed summaries/source data are handled separately for manuscript submission.

## Verification Status

The public release was checked by no-token Hugging Face readback. The following checks passed:

- The repository is public and ungated.
- The remote file list exactly matches the local staged release.
- Model card license metadata is `apache-2.0`, and the repository includes an Apache-2.0 `LICENSE` file.
- A no-token snapshot download succeeds.
- `SHA256SUMS` verifies every downloaded file.
- No Hugging Face token-looking strings were found.
- No `.secrets`, `__pycache__`, `.pyc`, or `.DS_Store` artifacts were present in the uploaded release.
- The README quick import check passes from the downloaded public snapshot.

These checks verify packaging, public access, checksum integrity, token hygiene, and import completeness for the released code surface. They do not claim that a full multi-GPU retraining run can be launched without the large excluded corpora, embeddings, and compute resources.
