The terms, in plain language.

The vocabulary behind sovereign, on-premise AI for law and government, defined without the jargon.

Sovereign AI

AI that an organization owns and controls end to end. The model and the data both run on hardware the organization holds, not on a vendor's shared cloud.

On-premise AI

AI that runs on hardware physically located at your site rather than in a remote data center. Processing happens inside your building, under your control.

Air-gapped

A system with no connection to the internet or any outside network. Because nothing can be uploaded or intercepted, air-gapped systems suit highly sensitive work like criminal cases.

Chain of custody

The documented, unbroken record of who handled a piece of evidence and what was done with it. A clean chain of custody is what keeps evidence admissible in court.

Charge-by-element matrix

A grid that maps each legal element of a charge to the evidence that supports it, marking every element as proven, disputed, or missing so gaps in a case are obvious at a glance.

Probative value

How much a given piece of evidence actually helps prove or disprove a fact in the case. Ranking documents by probative value puts the evidence that matters most at the top.

Entity network

A map of the people, organizations, and places in a case and the connections between them, built from the documents in the file.

Brady / Giglio

Disclosure duties from U.S. Supreme Court rulings. Brady requires prosecutors to turn over evidence favorable to the defense; Giglio extends that to evidence that could impeach a witness.

Grand-jury secrecy

The rule that grand-jury proceedings and materials stay confidential. Tools that touch grand-jury material have to respect that confidentiality.

CJIS

The FBI's Criminal Justice Information Services Security Policy, which governs how criminal-justice data must be handled, accessed, and protected. Modus V is designed to support CJIS-aligned handling; Imperium does not claim CJIS certification.

Tamper-evident audit ledger

An append-only log that records every action taken against a case file and makes any later alteration detectable, supporting chain of custody.
