Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-10-31).
Raw HTML fetched with curl. The page text reads 'In a recent 30 day period: 59,918 River sessions happened in 5,170 Slack channels, touching the work of 7,000+ people inside the company (~1,200 more...'. The passage is an exact prefix of that sentence. The bold tags around the numbers are an allowed difference.
