Evidence & Assertion Model
Claims, sources, contradictions, confidence, provenance, and review.
LABS · IN DEVELOPMENT
A shared way to move from objects, archives, and documents to assertions, evidence, uncertainty, contradictions, and human review.
THE QUESTION
Its sources, contradictions, uncertainty, machine interventions, review history, and final accountable authority.
WHAT IS OPEN
Claims, sources, contradictions, confidence, provenance, and review.
Where automated research stops and scholarly authority begins.
How model-generated research is documented.
Measures for accuracy, uncertainty, labor, and failure cases.
A small deployable example and implementation guidance for institutions.
THE BOUNDARY
Evidence schemas, review methods, and evaluation are open. Multi-agent orchestration, entity resolution at scale, production interfaces, hosting, and security are built for institutions. We say so plainly.
PERMANENT SCHOLARLY ARCHIVE
The complete specification and evidence schema are permanently archived on the European Organization for Nuclear Research (CERN) Zenodo repository for open scholarly citation across universities, museums, and research libraries.
