How to verify a request
- Match the complete documented user-agent where one exists. A match is only a clue.
- Look for operator-published IP ranges, reverse DNS, or signed-request guidance. None is attached to this record.
- 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.
