# What verification excludes

> The six permanent exclusions that keep the interface confirmable and the judgment private.

Verification is defined as much by what it excludes as by what it confirms. The exclusion list is deliberate and permanent. It keeps the interface confirmable while the judgment stays private.

## Excluded from every check

1. **Review reasoning.** How a reviewer reached a conclusion.
2. **Source evidence.** The underlying documents and data.
3. **Prompts and orchestration.** How automated preparation was driven.
4. **Scoring and criteria.** Any gate, threshold, or score.
5. **Private workpapers.** Internal drafts and working records.
6. **Client data.** Any real client content.

## Why the exclusions hold

<Info>
  A receipt is a proof about metadata, not a window into the work. If a check could reveal any item above, it would cross the [Disclosure boundary](/start/disclosure-boundary). Verification is built so that it cannot: the excluded material is never on the verify side to begin with, so no check, at any permission level, can return it.
