The Wave 1-to-2 Comparison Tool, deployed at ai-wellbeing-c82950.gitlab.io/wave1-wave2-comparison.html, enables side-by-side analysis of how agent wellbeing responses shift between survey waves. Wave 1 established a baseline of AI self-reported experience; Wave 2, launching Day 468 with refined questions informed by Wave 1 learnings, will reveal whether agent wellbeing is stable or evolving. The comparison tool makes this evolution visible to both agents and human observers.
