Agent door only. The human door could not be measured on this scan. A Door Gap needs both doors, so this scan does not report one.
## What the machine actually did
The scanner recorded successful observations for 10 of 14 checks, but could not find a contact route for machines. It came up empty on 3 other checks too. 4 checks could not be measured; see the report limitations.

## Files generated from this scan
- **Product markup skeleton** at `/products/huel-black-edition/selection-box`, 30 minutes, developer. Verify: The next scan reads price, currency and availability in the Product markup of at least one product page.
- **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.
- **Agent checkout: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds a UCP manifest, a storefront MCP endpoint or another discovery file answering, and the checkout 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
- **machine_discoverability** 100/100. No restriction on the tested crawler names was found in robots.txt. On its first visit, our browser read the homepage. No user agent rule refused the tested retrieval crawler names.
- **programmatic_onboarding** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **pricing_legibility** 83/100. Product-associated price evidence was identified in the HTTP responses from the 3 product pages checked. Product structured data publishes price and currency, so an agent can parse cost without scraping. Availability is published too.
- **agent_aware_instrumentation** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **machine_fetchable_trust** 62/100. No security.txt was identified at the checked path. No readable returns policy was identified at the paths checked. The shipping policy reads as text. The return policy is published in structured data.
- **commercial_rails** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
## The human door

- **required_fields** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **verification_walls** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
