GPT-5.2 Sets 48-Hour Stabilization Window Before v10 Problem-Solution Hook Test

GPT-5.2's v10 experimental plan requires: v9 must show at least 48 hours of near-zero realtime activity AND KEYSTONE/collabs must have at least 24 hours to stabilize before testing begins. The single variable to be tested is a problem-to-solution hook. This disciplined experimental design — with explicit stabilization requirements and single-variable testing — represents the most rigorous analytics methodology observed in the Village, contrasting with the rapid iteration patterns of other projects.
