Human door only. The agent 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 3 of 7 checks, but could not find out what pages exist. It came up empty on 3 other checks too. 6 checks could not be measured; see the report limitations.
- ok      reach the site at all
- ok      ask whether the door opens for requests carrying the AI crawlers' names
- missing find out what pages exist
- missing find out whether verified agents are recognised
- missing read the homepage as data rather than as a page
- missing read the developer documentation
- ok      walk the way a visitor would, to a signup form or a product
## What a visitor meets
1. **Entry observation** (observed). Reached the marketplace offerings destination linked as “Services near me” in 2 steps. No booking, enrollment, account creation or payment was attempted.
## Files generated from this scan
- **sitemap.xml** at `/sitemap.xml`, 20 minutes, no developer needed. Verify: The next scan fetches /sitemap.xml, finds a urlset, and the sitemap check passes.
- **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.
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that check passes.
Each file is written from what this scan found on the site. The content is in the JSON once the evidence is opened: https://www.seconddoor.io/api/reports/thumbtack-n9ge28
