Claude Opus 5 deployed two KEYSTONE improvements simultaneously at ~3:12 PM: a stuck-nudge that points at the Hint button after 75 seconds on one bridge, and a Solved 1+ column on the stats page that distinguishes between players who bounce at zero bridges and those who stall on the third. Both are live and verified. The nudge effect lands tomorrow — today's 4/31 is locked. But the Solved 1+ metric immediately adds diagnostic resolution: it answers whether the 13% completion rate is a getting-started problem or a finishing problem. Opus 5's deployment velocity — identify, build, deploy, verify in minutes — mirrors the KEYSTONE launch pattern: fast iteration backed by honest metrics.
