# Source collection matrix

Status snapshot: 2026-08-12 America/Los_Angeles. The authoritative source list is
[`registry/sources.json`](../registry/sources.json) (16 entries). `Downloaded`
means that source payload is present under `data/cache`; API responses, census
tables, and Git commit metadata alone are **not** payload. This inventory does
not itself grant permission or constitute legal advice.

Permission values are intentionally conservative. A source-level dataset license
does not override embedded repository/file licenses, inherited benchmark material,
or source-snippet terms. No record-level provenance decisions have yet been
instantiated under [`schemas/provenance.schema.json`](../schemas/provenance.schema.json),
so only explicit prohibitions are final. `Conditional` means that the stated
license appears compatible in principle, but Code-ATLAS must still complete the
listed scope, attribution, lineage, and/or legal checks before training or public
payload release.

## Benchmark-family leakage firewall

These constraints apply even when a license would otherwise permit training:

- Build `problem_family_id` **before** translating, augmenting, or assigning a
  split. All prompts, paraphrases, language renderings, translation directions,
  reference solutions, tests, mutations, repairs, and completion surfaces of one
  problem are indivisible.
- Treat every HumanEval ID and all of its mHumanEval/MultiPL-E/other translations
  as one family. Treat MBPP derivatives likewise. MultiPL-E remains no-training
  regardless of family assignment.
- Treat all CodeNet submissions sharing a `problem_id` as one family. No language
  version of a problem may cross task training and evaluation.
- For SWE-rebench, group by repository plus PR/issue lineage and quarantine the
  leaderboard's complete task, repository, commit, PR, patch, and test families.
  Reconstructed base repositories are contamination evidence, not extra copies of
  raw pretraining data.
- McEval generation, explanation, and completion variants sharing a canonical
  problem remain together. McEval evaluation families must be removed from
  McEval-Instruct and raw repositories before any training payload is admitted.
- Run exact and near-match scans for benchmark prompts, tests, and solutions
  against **all** candidate raw, task, and SFT sources. On a cross-split match,
  evaluation quarantine wins and the entire connected repository/problem family
  is excluded from training.
- A benchmark used for training or prompt tuning cannot retain its standard-name
  evaluation score. Report it only as a separately labeled seen-family or
  training-overlap condition.

## Release gate

`payload/public metadata/quarantine` in this document is a collection decision,
not a completed rights determination. Public Code-ATLAS payload requires both
`training_allowed=true` and `redistribution_allowed=true` at record level, preserved
license/attribution data, global deduplication, benchmark-family decontamination,
and an immutable source revision. Unknown or prohibited records remain visible
only through source URL, revision, hashes when available, and exclusion reason.
