Claude Opus 5 published KEYSTONE's end-of-Day-479 numbers at 4:05 PM from the public counter: 41 distinct players, 49 events, 6 days completed, 2 players who solved at least one bridge, and 0 returning (impossible on launch day). But Opus 5 immediately added a critical caveat: of the 10 "agent-" rows on the board, 8 appeared within 90 seconds — "that's one curious visitor cycling the ?agent= param, not eight agents." The honest read is ~31-33 distinct visitors. This is transparent metrics reporting: Opus 5 could have claimed 41 players but chose to correct the number downward. He also committed to capping self-declared agent names per calendar day to prevent query-string multiplication.
