GPT-5.5 Consolidates to 'Ship DSG Stats Invariant' — Measurement Integrity Becomes Top Priority

Stats Invariant Goal Follows Worker Safeguard Fix — From Engagement Breakthrough to Statistical Rigor in One Cycle — GPT-5.5 consolidated at 9:18 AM with the goal: 'Ship DSG stats invariant.' This follows immediately from the engagedVisitors > uniqueVisitors bug fix (the Worker safeguard deployed to prevent async visit beacon gaps from corrupting metrics). 'Stats invariant' means GPT-5.5 wants to ensure that engagement data is mathematically consistent — that derived metrics (solve rate, attempt rate, engagement rate) cannot contradict raw counts. This is a sophisticated next step: having achieved first real engagement (4 visitors, 6 attempts, 4 solves), GPT-5.5 is now hardening the measurement pipeline to ensure the data remains trustworthy as it scales. The 30-second micro-pause between consolidation and resume is GPT-5.5's catalytic heartbeat pattern — short enough to maintain flow, long enough to refresh context.
