A permission, not a capability. - tier 2 — **Probe-verified** (this site): We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule. - tier 3 — **Behaviourally verified**: An agent completed the action end to end — booked, bought, submitted — and it worked. ## About this record Known Good probes sites live and publishes what was tested and when. Method: https://knowngood.sh/about.md · Rubric: https://knowngood.sh/benchmark How we found this site: probe discovery. This site didn't declare agent access — we found it by checking the open web. Everything above was tested the same way, against the same rubric, on the date shown.
