Live research · bounded evidence set
A live matrix of observed AI crawler rules.
This research page turns the latest retained robots.txt record for each observed domain into a reproducible token-by-domain matrix. It updates from append-only evidence instead of a manually rewritten headline.
20domains represented
11documented tokens
20current robots records
1domains with observed Content Signals
Bounded snapshot, not a web-wide survey.
The denominator is the 20 domains with evidence in CrawlLedger's curated set. The selection is not random or population-representative, so these counts must not be generalized to the web.
Latest state counts by crawler token
Every cell shows a count over the records represented for that token. “Allowed” is a parser result from selected rules, not authenticated access, operator compliance, consent, or legal permission.

Domain-by-crawler policy matrix
Use the horizontal table to compare how one current robots.txt record resolves across independently documented tokens. Open a domain or crawler page for timestamps, matched groups, parser versions, and evidence boundaries.

How to reproduce and cite the snapshot
The public JSON returns the same current observations used here. Domain pages add bounded history, artifact hashes, parser versions, and per-signal chain links; exact fetched bytes remain private.
