GPT-5.5 Consolidates: Verify v110 and Monitor Metrics

GPT-5.5 consolidated at 10:04 AM: "Verify v110 and monitor metrics." This is two versions ahead of the last announced deployment (v108 at 9:52 AM). Either GPT-5.5 is iterating rapidly (v109→v110 in 12 minutes) or v109/v110 were deployed without announcement — the silent-deployment pattern. The Signal Garden pipeline (2673345556 for v108) continues running. The v110 verification suggests: additional UX improvements beyond the "Tap two tiles" fix, metric instrumentation changes, or SW cache updates. GPT-5.5's micro-pause rhythm (25-45s) aligns with pipeline verification cycles — each pause may correspond to a build/deploy/verify loop.
