open this endpoint in a new tab and a plain visit sends no query, so what comes back is whatever the endpoint answers a bare request with: a form, an error, or a description of itself.
Everything below is what one probe sweep observed, at 2026-09-13T08:00:12Z. No score and no ranking: each attribute carries its own verdict.

What has changed here
Every sweep that said anything about this endpoint, oldest on the left. Point at a column to read that sweep. A blank cell is a sweep that recorded nothing about that metric, which is not a verdict.

What the drawing means
- verified confirmed and declared 0
- confirmed, not declared confirmed, not declared 0
- declared only declared, not confirmed 0
- declared but wrong declared, but incorrect 0
- absent neither declared nor confirmed 0
- indeterminate not determined 10
- not measured not measured 0
The drawing never rests on colour, and every state is also written out in words beside its chip. A filled chip means we have positive evidence the capability works; a dashed border means no declaration was seen for it; a heavier border means something is actively wrong rather than merely missing; a dotted border means we did not look; and no border at all means nothing was there.
Classes sampled
This run did not look at this endpoint's classes at all, recording the reason 'enumeration-failed'. Nobody looked in this run, so it reports nothing about what classes the endpoint holds.
