Generated by googleReviewsChecker analysis v7 from the Newest-sorted Google Maps feed (100% headline coverage) · fetched 9/5/2026, 6:19:09 AM. Campaign-like months require ≥max(12, 3× active-month median, 2× same-calendar-month median in other years) reviews and ≥90% 5★. A high-risk campaign verdict requires those months to hold ≥40% of all reviews, ≥90% timestamp coverage, ≥12 active months, and ≥100 dated reviews including ≥30 credible reviews outside them. A contiguous ≥12-month high-volume regime is not escalated when ≥80% of flagged months fall inside it, ≥30 credible reviews agree within 0.2★, and burst share is ≤5%. Risk signals select among observed credible cohorts but never assign flagged reviews an invented star value. Indicators, not proof.
