Code-ATLAS Corpus Registry
This repository is the data-first foundation for adapting ATLAS to programming languages. It is intentionally a registry and split specification before it is a training corpus.
The scientific goal is to measure directed transfer among roughly 20 programming languages, fit loss-based scaling laws, and predict a data mixture for adapting a model to a low-resource or newly introduced language.
Publication contract
Every published payload record must be traceable to an immutable source artifact and must have a license decision that permits both redistribution and ML training. Records that fail either check remain in the public provenance registry as metadata-only entries; their source text is not republished or trained on.
The initial source inventory is in registry/sources.json. The record-level
contract is in schemas/provenance.schema.json. No source is admitted to the
training split merely because it is publicly downloadable.
Data roles
core_pretrain: natural repository code used for next-token pretraining and held-out loss measurement.parallel_aux: same-problem or translated programs used only in a separately reported transfer ablation.functional_eval: executable tasks that never enter training.metadata_only: redistributability, training permission, or artifact access is unresolved or prohibited.
Raw repository pretraining is ordinary causal language modeling over source files
and selected repository context. Issue descriptions, patches, execution traces,
and tests are useful task/SFT/RL data, but are not interchangeable with the
natural-code corpus used for the main ATLAS loss experiment. See
docs/what_code_pretraining_data_is.md for the record format and the boundary
between repository and benchmark data.
Split invariant
No file-level random split is allowed. Files sharing a repository lineage, fork or
clone family, near-duplicate cluster, or benchmark problem family must receive the
same split. See docs/split_protocol.md.
Current status
- Source registry: in progress.
- License and provenance audit: in progress.
- Per-language post-filter census: not yet frozen.
- Stack v3 record-level ingestion: one pinned shard validated; full 8,192-shard scan pending.
- Final language panel: not yet selected.
- Train/validation/test assignments: intentionally not created yet.
- Public provenance repository: https://huggingface.co/datasets/arpandeepk/code-atlas-provenance
- Public permissive payload: not yet created; record-level license and leakage gates must pass first.
