What we observe
We read X-Frame-Options, X-Content-Type-Options, Referrer-Policy and Permissions-Policy on the pages we read, and note pages that send them differently.
Why it is here: the evidence
Fact only No platform document and no independent study says it matters. We record it because it is true of the site, so it is never offered as advice about AI.
Source: No AI vendor documents what it weighs before acting; recorded as a fact. Source grade C: nothing published shows that AI systems use it.
Last re-checked ; due again within 30 days.
What we cannot see
Whether any AI system weighs them. No AI vendor documents what it checks before acting on a site.
Why there is no advice here
Recorded as a fact; no platform documents that it matters to AI systems, so this page gives no advice about it.
Where it matters for the people who visit a site, its own area covers it: Security posture.
