## Files generated from this scan
- **Complete the merchant fields in product markup** at `snippets/seconddoor-product-jsonld.liquid`, 30 minutes, developer. Verify: The next scan reads priceValidUntil and the available owner-reviewed return and shipping fields alongside price, currency and availability in the Product markup it samples.
- **Variants missing a GTIN or a brand** at `catalog-identifiers.csv`, 5 minutes, no developer needed. Verify: The next scan reads the catalogue feed and finds a valid GTIN on at least nine in ten variants and a brand on at least nine in ten products.
- **Organization structured data** at `homepage`, 15 minutes, developer. Verify: The next scan reads Organization and WebSite nodes in the homepage JSON-LD and the structured data check passes.
- **security.txt** at `/.well-known/security.txt`, 10 minutes, no developer needed. Verify: The next scan fetches /.well-known/security.txt as text and the security.txt check passes.

## The agent door
