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 5 of 7 checks, but could not find a contact route for machines. It came up empty on 1 other check too. 7 checks could not be measured; see the report limitations.
- ok      reach the site at all
- ok      find out whether machines are welcome
- ok      ask whether the door opens for requests carrying the AI crawlers' names
- ok      find out what pages exist
- missing find a contact route for machines
- ok      read the homepage as data rather than as a page
- missing read the developer documentation
## What a visitor meets
1. **Entry observation** (unmeasured). The homepage was read, but no supported entry destination was identified in the visible links checked.
## Top issues
1. **No valid security.txt was identified at /.well-known/security.txt.** (machine_fetchable_trust)
   - Evidence: /.well-known/security.txt: the response did not validate as a security.txt.
   - Evidence: Checked URL: https://www.starlingbank.com/.well-known/security.txt
   - Fix: Publish /.well-known/security.txt with a contact route.

## Files generated from this scan
- **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.
- **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.
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/starlingbank-gt3nqc
## The agent door
