Verification model

How a source becomes a verified record.

Four steps between the register and your systems. The third is the one most monitoring tools do not have.

Capture

The monitor fetches the source document and stores the response with a checksum and a timestamp. The source URL is recorded before anything is read.

A source document captured with its URL, checksum and timestamp recorded before anything is read.

Classify

AI extracts the fields and classifies the change: new rule, amendment, comment period, effective date. Each classification carries a confidence score.

A captured change classified into its fields with a confidence score attached to each.

Review

Records below the confidence threshold route to a human verifier. The verifier checks each field against the source text and signs the record with their ID.

A human verifier checking a low-confidence record against its source text and signing it with their ID.

Publish

The record is released with its source URL, capture timestamp, verifier ID and final confidence score attached. Field-level accuracy runs at 99.5%.

A published record carrying its source URL, capture timestamp, verifier ID and final confidence score.
