Checks 1–7

EVIDIQ Lineage is the supply-chain gate for autonomous coding agents. It verifies that a claimed dependency really exists, scores an npm or PyPI dependency set against fourteen deterministic rules, audits licenses, and issues signed SBOM and AI-BOM inventories before any package is trusted.

outside the census

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
