adduce

A local research-artifact auditor.

adduce checks whether a paper's claims, code, configs, data, dependencies, remote models, precision settings, and generated results still agree with each other before submission. It also drafts repository-observable NeurIPS/ACL checklist items, an ACM Artifact Appendix, archival metadata (RO-Crate, Croissant, CodeMeta, Zenodo), and a claim-by-claim evidence trail for author review.

The north-star question: for every number in the paper, can I point to the artifact that produced it, and will that artifact still produce it elsewhere?

Install

pipx install adduce        # or: pip install adduce / uvx adduce
adduce check .

PyPI 0.1.2 is the current release.

Upgrade commands per installer, and the caveat that existing installations do not update themselves, are in docs/cli-reference.md.

Adduce is beta software. Findings are static-analysis signals for review, and scores, tiers, and reviewer-time estimates are provisional pending calibration against manually reviewed real repositories. Generated submission material is always a draft.

Built-in checks are offline by default. Public-metadata requests require the explicit --online or pin-remotes modes and use a bounded public-HTTPS resolver; pre-existing cache entries never count as network evidence. Read the security model before using network, provider, plugin, or dynamic-execution features on untrusted input.

What it reports

Verbatim excerpt from adduce check on nanoGPT at commit 3adf61e. Omitted whole: eight of the fourteen category rows, the no-paper-sources notice, the inferred claim-trail block, the last two fixes, and the closing Next: line. Nothing is reworded, and every … is the tool's own truncation marker.

Top fixes (largest score gains first)
 1. Extend the seeding helper to cover: python (random.seed), numpy (np.random.seed or
default_rng).
     adduce fix --scaffold seeds
 2. Set torch.backends.cudnn.deterministic = True and torch.backends.cudnn.benchmark = False in
the seeding helper.
     adduce fix --scaffold seeds
 3. Declare dependencies, then pin them (pip freeze, pip-compile, uv lock, poetry lock).

Statuses are detected signals from static analysis, not a certification of reproducibility.

Location-bearing findings are anchored to source lines—the TF32 finding above points at train.py:107, and the unpinned hub call at model.py:238. Six of the fourteen categories that applied to this repository are shown above; the full run also covers Documentation, Run Traceability, Checkpoint & Experiment State, Notebooks, Remote Artifacts & Rot, Versioning, Access & Legal, and Archival Readiness.

When a manifest declares claims, the report adds a per-claim trail. Trimmed output from adduce manifest followed by adduce check on the synthetic positive-control repository corpus/synthetic/synthetic_rounding_match in this repository, where the paper states an accuracy of 81.4 and the logged run recorded 81.37:

Claim trails (manifest; draft claims remain inferred until author-confirmed)
  paper/main.tex:3  ·  "accuracy of 81.4" [inferred draft]
    metric      results/eval.csv:accuracy  (found: 81.37)   ~ rounding vs paper
(81.4) ✓
    log         results/eval.csv ✓
    status      PARTIAL

Every finding carries a status (pass / partial / fail / not-applicable / unknown), a confidence, available file:line locations, and a concrete remediation. partial is used when the repository supports only part of a check.

Honest limits

adduce reports detected signals, never a certification of reproducibility. It never says a repository "is reproducible", and it never assesses execution-based badges (Results Reproduced/Replicated) — only badge eligibility signals. Static analysis never implies execution: the opt-in --online/pin-remotes (network) and reproduce (execution) layers are the only parts of adduce that leave the offline, static default, and both are explicitly fenced.

Scores and named tiers are experimental prioritisation aids, not calibrated quality grades. The validation corpus protocol defines a pending release-quality gate, and no effectiveness or calibration claim is made until its human-review requirements are complete.

The full list of limits — automatic claim inference as scaffolding only, the static-resolution ceiling, remote pinning as a forward guarantee rather than historical recovery, dynamic reproduction's non-sandboxed execution, and more — is in docs/honest-limits.md.

Documentation

Adduce ships 78 rules across 17 categories, each gated on whether it applies, so an inapplicable category drops out of scoring rather than counting against a repository.

Full documentation — every rule, the CLI reference, the manifest and claim-trail model, CI recipes, generation safety, the optional LLM layer, and the security model — starts at docs/index.md. The rule reference and honest limits are the two pages most worth reading before relying on a score.

Contributing

Contributions are welcome, especially incorrect or low-value finding reports. See CONTRIBUTING.md for the development setup, design constraints, and how to add a rule. Report vulnerabilities privately under the security policy.
