Does every change to the graph wait for approval?

No. Controls differ by operation. Audit Graph proposals use a review and apply workflow. Case Chat can change case content directly, which is why the investigator inspects what a response adds.

Is a status a statement that something is true?

No. Established, Alleged, Not established, and Denied are assessments made in the case from the records reviewed. They can change when new material arrives.

Does a source reference certify a claim?

No. A source marker shows where a statement came from. It does not certify that the statement is true.

Is a model score the probability that a claim is true?

No. A score describes model output. The investigator reads the records and decides what they support.

Does Nexus decide what is true?

No. Nexus organizes the material and assists the examination. The investigator examines the evidence and remains responsible for the finding.

Nexus Evidence Review

Evidence Review in Nexus

Nexus helps investigators inspect source context, pursue gaps, and review proposed relationship corrections. Keep the claim, its speaker, and the underlying relationship distinct as the case changes.

Start From the Source Context

A source can report an allegation, document an association, or repeat another source. Those are three different contributions to a case.

Open the record behind a relationship and read the passage, the date, and who is speaking. A relationship is only as strong as the record it rests on.

One record, read closely

Public record

B05, website capture

Payment pages built to look like a toll service. They show a logo, business details and the date of the supposed unpaid toll.

Speaker: The site’s operator
Supports: What the site offers and asks for
Does not support: Who operates it

Supported and Disputed Relationships

Each relationship in a case carries an assessment in words. The four assessments mean different things, and none of them is a verdict on the world.

Established

The reviewed records support the relationship as stated, for the dates they cover.

Alleged

A source asserts the relationship. The assertion is kept with its speaker.

Not Established

The reviewed records do not support the relationship. It may still be true.

Denied

A source denies the relationship. A denial is also an attributed statement.

Ask Questions in the Context of the Case

AI assistance is part of the investigative process. It works from the material in the case, and the investigator checks the response against that material.

Case Chat

Ask a question about the case or selected subjects. Case Chat supports inquiry and can add to or change case content, so the investigator inspects what a response adds.

Audit Graph

Audit Graph proposes relationship assessments and corrections. Each proposal is reviewed and then applied or declined through its own controls.

Case Brief

The Case Brief orients a reader to the case as it stands: the question, the subjects, and the current state of the work.

Report

The report is a separate output. The investigator inspects it against the case before it reaches a reviewer.

A focused question

Which domains have a capture or report behind them?

Check: The answer should list only domains with their own record.

A focused question

Who is behind the texts?

Check: The answer should say the record does not name an operator and cite B02.

Review a Proposed Correction

From the unpaid toll text case

Audit Graph proposes a correction. The investigator reads the basis and applies it, qualifies it, or declines it. Two proposals from the unpaid toll text case show both outcomes.

Applied

Keep Each Domain on Its Own Record

A working note treated every reported toll domain as one group’s operation. Shared wording and the FBI’s note that the scheme moves between states (B02) connect them. No record names an operator.

Effect: a single operator stays Not Established. Each domain keeps its own capture or report.

Declined

Treat a Text Naming the Driver’s Agency as Real

The proposal reads a text that names the driver’s own toll agency as a genuine notice. The agencies say they do not text drivers for personal information (B07).

Effect: the claim stays Denied. The text keeps its own record as an impersonation.

The Finding and the Next Search

A correction changes the finding in a specific place. The output states what was revised, what remains supported, and which question is still open.

The public record establishes that, from March 2024, texts impersonating state toll services sent drivers to payment sites posing as those services. The FBI received more than 2,000 complaints from at least three states by April. The FTC warned in January 2025 that the scheme had spread nationwide. The agencies named say they do not text drivers for personal information. Each malicious domain is established by its own capture or report. The record does not name who sends the texts.

Still unresolved

Who sends the texts, and which new domains will carry the next wave.

Next search

Search for new domains that use the agency names, and watch the agencies’ notices for a change.
