## Headline sentences the numbers support (site as actor; wording fixed by gate 2 r2)

"For 12 of 12 comparable products among the 12 Capterra-listed pure-play assessment products, two or more review sites displayed at least one exact matching review signature on 2 September 2026; the median R_p across the 12 comparable products was 0.481."

"Capterra and GetApp each displayed a profile in all 12 matching groups, Software Advice displayed a profile in 10, and G2 and Trustpilot displayed profiles in none."

"Across those 12 matching groups, the review sites displayed sub-ratings that yielded 7 corroborated classifications, 0 discordant classifications, and 5 unassessable classifications under the prespecified check; none establishes review identity."
