AI crawler rules in robots.txt
CrawlLedger evaluates a versioned registry of first-party-documented crawler tokens against the parsed robots groups.
Tracked crawler observations
These are parser results for the published robots rules, not authentication or legal conclusions.

How to interpret this record
Robots rules address cooperative crawl access. Content Signals express downstream-use preferences. llms.txt is publisher guidance, while RSL can express machine-readable terms. CrawlLedger only reports what it observed and parsed.
