Agent Evidence Vectors timeline

Agent Evidence Vectors supplies saved records with expected outcomes for developers building evidence verifiers. Its fixtures cover formats and contracts involving agent actions, approvals, task completion, MCP, A2A and software supply chains. It is a conformance testing resource, not a foundation model or a universal agent-safety certification.

The Hugging Face repository was created on October 24, 2026. A November 3 mirror identifies source tag v0.32.1 and contains 2,736 cases across 57 corpora. The tagged source’s installation guide still names v0.32.0 as the published package and describes repairs as unreleased, so users should distinguish the downloadable dataset snapshot from package availability and pin the exact revision they evaluate.
