Timestamped observations of public machine-readable policy files. The states below describe fetched records and parser results; they do not establish legal permission.
Current means the latest ledger event for each observed signal. Conditional 304 responses reuse the prior artifact hash while extending the event chain.
3073d1e371af…CrawlLedger evaluates a versioned registry of first-party-documented crawler tokens against the parsed robots groups.
These are parser results for the published robots rules, not authentication or legal conclusions.

These emerging robots.txt extensions state publisher preferences about downstream use. CrawlLedger records the declarations without treating them as enforcement or legal permission.

The public timeline exposes hashes and metadata. Exact fetched bytes stay private to avoid redistributing source files.

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.
