Observed exact versions and registry metadata

Publication age and licenses come from deps.dev metadata. They are context—not a maintenance, legal or portability verdict.

Exact identities in, explicit limits out

Only exact npm and PyPI tuples are enriched. Reported SPDX expressions are metadata; no compatibility, obligation or legal conclusion is inferred.

Retrieval, parsing, matching and publishing use no generative AI model.

i6eal (2026): LangChain — exact AI dependency evidence dossier, data state 19 Jul 2026. https://i6eal.de/en/tools/ki-abhaengigkeitsatlas/paket/langchain-2b3b6a0b/

Reading this dossier

Does package presence prove that a provider is used?
No. Even a direct interface declaration does not establish configuration, credentials, procurement, data transfer or an API call.
Why are exact versions required?
OSV and registry metadata can be linked reproducibly only to an observed package@version tuple. The collector never substitutes a newest release for a range.
Does a missing row mean the dependency is absent?
No. It means not observed within the bounded files and repository checkpoint. Incomplete trees and parser failures remain explicit.

Need a permanent dependency evidence trail for another public code cohort?

We build source-backed data products with stable identities, reproducible joins and boundaries that remain visible.
