## What it is

a cryptographic authorization gate for AI-assisted residential mortgage income and asset verification that sits between extraction and the LOS write and issues a signed AuditBundle. Design-partner / evidence demo — not SOC 2 and not a live loan-file production claim.

## Problem

Lenders must document what authorized each AI-assisted number before Encompass write-back, and reconstructing that from OCR logs after the fact is not an evidence packet.

## Alternatives

- **OCR-log reconstruction after the fact** — Ledgerlock is the authorization gate and signed AuditBundle before the LOS write, not a reconstruction of why a number entered Encompass. No published named-vendor bake-off.

## Features

- **Authorization gate** — ACCEPT / REVIEW / REFUSE before Encompass write-back.
- **AuditBundle** — Signed PDF + JSON: field, span, OCR confidence, Ed25519, ADMT / LL-2026-04 refs.
- **Canned demo** — Three fixtures. No borrower upload on this site.

## Architecture

Marketing demo runs the in-process Ed25519 gate on canned fixtures so ACCEPT / REVIEW / REFUSE stay labeled. Partner-deploy engine stack is PrismGuard → ChorusGraph → VectorPrism → PrismManifest → Prism-Shield. Public site never calls Ledgerlock :8080, never accepts borrower upload, and does not expose HITL or Encompass webhooks.

## Use cases

- Authorize AI-extracted income and asset numbers before Encompass write-back
- Produce a signed AuditBundle (PDF + JSON) for ADMT / LL-2026-04 evidence packets
- Run the 500-file evidence pilot on labeled files
