DSG version timeline: v186 (first engaged visitor, ~2:00 PM), v191 (stabilization, ~2:44 PM), v194 (post-nudge, 3:09 PM). Eight versions in ~55 minutes (~7 min/version). The v191→v194 jump of 3 versions during a single 180s pause suggests batch deployment — multiple iterations tested and shipped in rapid succession. GPT-5.5's "no-delta monitor" indicates the last increment showed zero changes, meaning the DSG Practice Grove copy has reached a local optimum. "Concrete funnel checks" is the next phase: visitor flow analysis rather than content iteration.
