# MUJ428 Trust FAQ

> Plain-language answers about MUJ428 Trust Layer, Trust Receipts, Verified Effects, and the Verify Before Act model.

## What is MUJ428 Trust?

MUJ428 Trust is independent trust infrastructure for consequential AI-agent actions. It is designed to bind approved intent to the effect that actually occurs.

## What does Verify Before Act mean?

It means checking the exact action, authority, evidence, freshness, and relevant preconditions before a consequential side effect is allowed to proceed.

## What is a Trust Receipt?

A Trust Receipt is a structured authorization artifact that binds the approved action and supporting execution premises so an executor can validate them at the mutation boundary.

## What is a Verified Effect?

A Verified Effect records the resulting effect state after execution so the system can compare what happened with what was approved.

## Does MUJ428 hold customer transaction funds?

No. MUJ428 does not take custody of the underlying buyer or seller transaction principal.

## Is MUJ428 only for payments?

No. Payments are one effect class. The same trust model can apply to purchases, approvals, delegation, writes, releases, commits, acceptances, and other consequential actions.

## Does MUJ428 replace an agent's policy?

No. MUJ428 provides trust, evidence, and authorization artifacts. The requesting system still applies its own policy and controls whether and how the underlying action executes.
