How this was measured

Measured by Roentgen 1.28.1 on 2026-10-02. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.

This is detection coverage, not a verdict — it counts the conversion tactics we could prove are present, out of the 10 that apply to an affiliate funnel. A low count means we did not detect those patterns, not that the funnel is weak.

Against all 1,747 multi-step funnels, more conversion tactics than 20% of them.

Walk 67 links on the entry page, 60 walkable. 1 matched a funnel step; we captured 2 pages in all, this one included.

Absence is a measurement, not a recommendation: we do not know why a tactic is missing, whether it belongs here, or whether adding it would change anything. Where a walk stopped early, a tactic living deeper would also read as not detected.

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.
