    "Verdicts read rendered text, never HTML source. A first pass of this run matched marker strings in the page source and scored four passes as blocks: Cloudflare leaves its challenge script on every page it has already cleared, and the PerimeterX sensor sits on pages that loaded perfectly. Those rows are not in this dataset; the method that produced them is recorded here so the same mistake is not repeated.",
    "A second pass sampled the page once at a fixed ten seconds and scored challenges that were still clearing as blocks. Every check here instead polls for the site's own content for up to 45 seconds, and a pass records how long it took.",
    "DataDome blocked three times out of three down one French residential exit, and three out of three down one flagged pool exit. Its block page named the address. Six other French exits, same profile settings, passed on the first visit, and so did both arms of the ablation. One address is not a sample, and no claim about a reputation-sensitive wall should be drawn from repeat hits down a single exit.",
    "Every exit in the managed proxy pool used by the repeat-flagged segment is listed as a proxy address by ip-api, and three of eight resolve into hosting ranges. Cloudflare cleared anyway, but DataDome and PerimeterX weight address reputation heavily, so that pool suppresses results that have nothing to do with the browser.",
    "wayfair.com held its PerimeterX press-and-hold wall on every exit where the navigation completed, flagged and clean alike. This is the clearest negative result in the run and is not attributable to the address.",
    "This run has one subject. The August run paired AntiBrow against a stealth-plugin Playwright; that comparison was not repeated here, so nothing in this dataset is a competitive claim.",
    "Leak checks (WebRTC, timezone against exit, navigator languages, OS against UA) were not part of this run. The August run covers them.",
