How this was measured

Measured by Roentgen 1.25.1 on 2026-08-20. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.

Coverage is detection coverage, not a verdict — it counts the conversion tactics we could prove are present, out of the 11 that apply to a saas funnel. Per device: desktop 20 · mobile 20.

Playbook match — which funnel play this page runs — measured, evidence-quoted

We ran these passes on the pages we captured and found nothing to show. That is a measurement of this funnel, not a recommendation — and it is a different statement from a layer we never ran, which does not appear here at all.
