Vantage
Where the request came from. Origins serve differently by geography and IP reputation, so an observation is only comparable with another taken from the same place. Everything here is measured from GitHub runners in the US and EU. More- gha-ubuntu
Policy posture
Whether anyone actually decided. Deliberate means robots.txt names AI crawlers by token. Inherited means it names none, so whatever AI policy exists is a side effect of generic rules. Blanket means one rule for everyone. Absent means no robots.txt at all. More

Every answer-surface crawler is allowed. An agent asked about this site can read it.
This domain did not respond on its last crawl, so it has no score. timeout An unreachable site is recorded as unmeasured, never as a zero.
Extraction profile
How cheap this page is for a retrieval pipeline to chunk. Recorded and published, deliberately not scored: it describes a shape rather than a pass or a fail, and compressing it into the grade would destroy the useful part.

Crawler policy
Read from xnhau.bio/robots.txt. A crawler is listed as blocked when the rules deny it the site root. This operator names 16 AI crawlers explicitly, which means the policy is deliberate rather than inherited from a wildcard rule.

No mark at this score
The embeddable mark starts at grade B, because offering a graphic nobody would put on their own site is a pretence rather than a feature. The list above is the useful version: for most sites the points are concentrated in two or three changes. How the mark works.
The neutral mark above exists and is free to use if you want to show that the site is independently measured whatever the number says.
