What the rule can and cannot do
Robots.txt expresses an access policy to compliant automated crawlers. It does not authenticate the sender, remove content already collected, or guarantee that a model will use or not use content.
How to verify a request
- Match the complete documented user-agent where one exists. A match is only a clue.
- Use the operator-published check: Published IP ranges.
- Keep the observed request, operator documentation, and any inference as separate fields.
JavaScript behavior
The cited operator material does not verify JavaScript rendering. Serve useful HTML before client-side JavaScript where possible.
