Jev Evidence

A multiple-choice visual QA dataset for candidate-dependent evidence, published under the tudo-vn account: each item has one image, one question and two candidate sets of 3 to 10 options, each set needing a different evidence region. For research and development only; annotations are CC BY 4.0.

A lightweight, auditable testbench for Jev as a typed decision primitive: every real API call appends to an append-only log, evidence is frozen under SHA-256 hashes, and the headline result is a preregistered negative.

Agent governance integration where Jev judges two Noul checks per tool call (beyond scope, destructive), an admission policy decides which judgments may become evidence, and admitted evidence degrades Trust, Delegation and Authorization in persistent R2R relation state.
