Latest aggregate-cohort evidence

86 distinct sites make up the measurement cohort this page's aggregates describe, and the date above is the newest eligible evidence inside that same cohort. Across all committed cohorts, 99 sites have at least one successful load.
Across these measured sites: 0 current, 0 stale, 86 unknown. Each site is dated by its newest eligible visit in this cohort.
Today the aggregate cohort also holds the newest eligible evidence in the committed corpus. This is not the cohort every report page uses. Each report ranks against its own exact cohort, and most committed pages carry a different one than this: a page compares only against scans that share its schema revision, methodology, tracker catalog, role taxonomy, metric contract, producer and requested-GPC state. Where no cohort reaches fifty sites, that page falls back to fixed thresholds instead. A scan run today records the current methodology, and no committed cohort matching its exact tuple, under either requested-GPC state, has reached the 50-site floor, so it is ranked against fixed thresholds and not against this number. Each percentile card names its own denominator, and the methodology states the rule. Category medians are published one cohort per category and span 3 cohorts in total, so no single cohort backs every published aggregate. Current means no more than eight days old. It does not mean every site was refreshed in that window. A site that loaded but whose evidence was cut short, by a request cap or a censored family, is counted as covered and never as measured, and coverage also includes visits in other cohorts. 966 committed reports use frozen schema v1 and 63 use schema v2; the methodology states what v1 evidence can and cannot support.
