This entry runs no foundation model. Every finding below is quoted to the vendor’s own document, or marked not disclosed where the vendor publishes nothing.

Model provenance

No foundation model. Ruff does not run one, so there is no model provenance to record. A static analysis tool: a Python linter and code formatter written in Rust, with over 900 built-in rules and automatic fix support, replacing Flake8, Black and isort. Established from the product’s own public documentation and what it does. If that is out of date, tell us at right of reply.

Who controls it

Not yet assessed. We publish a sovereignty position only where the vendor documents one — we do not infer it from a domain or a company name.

How this entry is set

Vannus records, from the vendor's own published documents, the legal entity a customer contracts with, the country that entity sits in, and the governing law of its terms — and whether the vendor runs its own model or resells someone else's. Each finding is quoted to its source and dated, or marked not disclosed where the vendor publishes nothing. No paid placement on a record, in the catalog or in search — affiliate status is walled off from the record, enforced by a test in the build. See the methodology →
