# Scans and issues

> How scans produce actionable issues in Atlios.

A scan checks a store's catalog and storefront signals, then turns findings into
issues that teams can review and resolve.

Issues are the primary review surface in Atlios. They help teams focus on the
catalog work that needs attention, including missing data, invalid values,
duplicate identifiers, weak image metadata, and storefront verification
failures.

## Scan coverage

Atlios checks product data, variant data, cross-product conflicts, product
images, and storefront rendering signals. Coverage can expand over time as new
quality rules are added.

## Issue review

Each issue should answer three questions:

* What is wrong or worth reviewing?
* Which product, variant, or storefront page is affected?
* What action should the team take next?

## Issue sources

Most issues come from catalog scans. If you connect [Google Merchant
Center](/product/google-merchant-center), Google's product disapprovals and
account warnings appear in the same inbox, prefixed `GMC:`. Filter by rule to
focus on one source.

When the scan and Google flag the same field on the same product, Atlios merges
them into one issue that carries both source badges. It counts once, and
resolving it clears both signals.

## Suppression

Some issues are valid exceptions for a specific store or product. Suppression
lets teams intentionally quiet those issues without losing scan history.
