# BioCandidateRanker Training Library

**中文说明见下方 [中文说明](#中文说明) 一节。**

This repository is the organized, license-compliant training library of the
[BioCandidateRanker](https://github.com/liubuing/BioCandidateRanker) project — a host-aware multimodal enzyme
candidate scoring research system whose first trained task predicts `log10(kcat)` from
protein sequence, substrate molecular graph, organism/EC/reaction context, and optional
FBA features.

It packages everything needed to **reproduce the exact training setup**: the frozen
homology-cold split assignments, ingestion audit manifests, source identity hashes,
external evaluation selections, and the official software release archive.

> **What is deliberately NOT here:** the UniKP/DLKcat measurement rows themselves
> (protein sequences + substrates + `kcat` values). The upstream compilation has no
> redistribution grant on record (`license: unknown`, record-level provenance
> corpus-level only), so the project's fail-closed license governance
> (`configs/data_license_inventory.json` in the archive) marks it
> `redistribution: not_verified` and blocks any measurement row from shipping in a
> public archive. See [Reconstructing the full training corpus](#reconstructing-the-full-training-corpus)
> to rebuild the corpus from the original public source and verify it bit-for-bit.

## The frozen homology-cold split

The development corpus is split **protein-homology-cold** with MMseqs2 `linclust`
(30% min identity, 80% coverage, coverage mode 0, seed 42), producing 2,204 clusters.
Whole clusters are assigned to a partition, so no protein family leaks between
train and evaluation:

| split | rows |
|---|---|
| train | 13,470 |
| validation | 1,684 |
| test | 1,684 |

The split is keyed by `source_row` (the 0-based row index in the original
`Kcat_combination_0918_wildtype_mutant.json`), so it can be applied to any
byte-identical copy of the source file:

```python
from datasets import load_dataset
import json

split = load_dataset("<repo-id>", data_files="data/homology_split.parquet")["train"]
# row: {"source_row": 0, "sequence_id": "seq_...", "cluster": "seq_...", "split": "train"}
```

**Note:** the split manifest contains cluster/row/split assignments only — no
sequences and no `kcat` values — which is exactly why it is redistributable while
the corpus itself is not.

## Reconstructing the full training corpus

1. Obtain `Kcat_combination_0918_wildtype_mutant.json` from the original
   [UniKP repository](https://github.com/Luo-SynBioLab/UniKP) (the file is also the
   wildtype+mutant kcat compilation distributed with
   [DLKcat](https://zenodo.org/records/6438262)).
2. Verify the frozen source identity:

   | field | value |
   |---|---|
   | SHA256 | `13643b0b36374f8d3f64d8b014882cf1b3b58946eeaae2b9dcd59e8b2c2d6719` |
   | size | 12,132,719 bytes |
   | rows | 17,010 |

   The audit on this machine confirmed a byte-identical copy (2026-10-24).
3. Run the project's audit and training CLI (included in `release/*.zip`) as
   described in `RECONSTRUCTION.md`.

| Temporal absolute-kinetics pool | 18+ CC0 / CC-BY-4.0 deposits | CC0 / CC-BY-4.0 per source | readiness audits, accepted-component FASTA, row mapping (curation pool below its gates — never scored, **not** a benchmark) |

## Release archive

`release/software-implementation-v10-redacted.zip` is the official deterministic
release archive (`software-implementation-v10`): every Git-tracked source file plus
38 frozen evidence artifacts, built by `scripts/build_release_archive.py` with
license-ownership verification and absolute-path redaction. Its embedded and sidecar
manifests carry per-file SHA256 hashes; the archive SHA256 is
`34e42f5b211bd590b785abe3ff59ac2cfaaca801328ddef68c9b303044b394d8`.

The archive includes the trained baseline checkpoint
(`artifacts/full-homology-baseline/best.pt`), which the license inventory explicitly
permits as a derived artifact (weights are not a redistribution of measurements).
