Every legal assertion made by federal courts since 1951, extracted, structured, and source-traced to the paragraph. Jurisdiction-mapped. Machine-readable. The verification infrastructure your legal AI needs before it ships.
The cases were real. The jurisdiction was not.
The model is not broken. The infrastructure was never built.
Retrieval-augmented generation returns documents. It doesn't tell you if a holding still applies, whether the jurisdiction agrees, whether what was cited as precedent was dicta, or whether the law moved since the model was trained. Legal authority is not a document. It is an assertion, made by a specific court, in a specific jurisdiction, at a specific time, with a specific precedential weight.
KeyCite and Shepard's are the best tools available today. They were built for human lawyers reading PDFs, not for AI systems that need structured, assertion-level data at query time. We built what comes next.
Chevron deference requires courts to defer to agency interpretations of ambiguous statutes. See Chevron U.S.A. v. Natural Resources Defense Council, 467 U.S. 837 (1984).

The only system that knows the difference between a dissent and a holding.
Every AI system that retrieves legal text can retrieve a dissent. Most can't tell you it's a dissent. Omniarch tags every assertion with its speaker: majority, concurrence, or dissent. Citing a dissent as precedent is not a subtle error. It is the kind that surfaces in front of a judge.
The only system that types every legal edge as a duty, a right, a privilege, or a liability.
An obligation imposed on a party is not the same as a right granted to one. Omniarch applies Hohfeld's legal typology to every extracted assertion. The type of legal relationship determines what the AI can safely conclude from it.
The only system that tracks three separate clocks.
When a case was decided. When the statute it interprets took effect. When the rule it establishes applies. These three timestamps are often different. Systems that track only one draw incorrect temporal conclusions. Omniarch tracks all three.
Every claim your AI makes should survive a judge's question. Omniarch gives you the structure to verify it before they ask.
