ZH checks every record against its source document, deterministically, and returns a verdict and a receipt. It checks again when AI reasons over those records, and once more before anything goes to your clients. Failures go back for repair; what can't be repaired goes to a person. It runs inside your environment. Your production data stays in your environment.
More than 11.6 million verification runs in production as of September 17, 2026.
The problem
A field that doesn't match the filing it was keyed from.
A record nobody can trace back to a document.
A review team checking every row by hand, and never catching up.
Cleaning tools fix formats and duplicates. They don't know whether the record is true to its source. ZH does one thing: it checks.
Unstructured in, structured out
Most dirty data starts as paper: run sheets, scanned filings, PDFs, spreadsheets nobody trusts. The model reads them and proposes a structured record. ZH checks every field against the page it came from before the record enters your store. What it can't trace, it flags for a person.

Flagged for a person: the reservation clause could not be read from the source page.

How it works
Clean data in, checked when AI interprets it, checked once more before it reaches your clients. A failed claim goes back to the model, up to five passes. What it still cannot ground lands with a person as a named exception. ZH never writes the fix.

What you get
Per claim: VERIFIED, FABRICATED, MISSTATED, CONTRADICTED, CONFLICTING_EVIDENCE, OUTDATED, UNSUPPORTED, NOT_REVIEWED.
What was checked, against which document, when. SHA-256 audit chain, Ed25519 signed.
What the model fixed, what it couldn't, and the exact rows a person needs to look at.
Intake, interpretation, delivery. Fail closed at each. Anything ZH can't trace to a source is not passed through as clean.
Proof
