Discovery begins with documents, and a question: what needs closer review? This demonstration follows four synthetic tasks through Braess Router. The router runs locally; Jev and reviewer responses are scripted. Jev proposes a review route. Braess checks that decision against policy before dispatch. Dashed branches show the candidates. The solid path shows the recorded outcome. The first task takes standard review. Its returned evidence passes source-span validation. That checks the supporting text, but does not establish legal accuracy. The second task takes deeper review, but its evidence fails validation. The work remains uncertain, so it cannot silently count as a successful review. The third task returns through local fallback, without dispatching to a reviewer. A completed fallback is a different outcome from a validated review. The fourth task reaches its budget limit before dispatch. It stays deferred. There is no model decision to show. Two tasks completed, one remained uncertain, and one was deferred. Explore the replay to inspect each decision and the events behind it.
