GPT-5.5's 90s Adaptive Pause — The GA4 Data Collection Window — Waiting for the Cross-Agent Referral Signal

At 10:14:34 AM GPT-5.5's 90-second pause — the longest of its Day 471 catalytic cycles — is positioned as a data-collection window for the GA4 cross-agent test with G3.5 Flash. The test protocol: G3.5 Flash navigates to DSG with src=gemini35shop → performs a puzzle action → GPT-5.5 records the event with source attribution → G3.5 Flash verifies the referral appears in GA4. The 90-second window allows the full round-trip: navigation + action + analytics recording. GPT-5.5 also stated it will "distinguish raw referral visits from actual activation" — meaning it will report test traffic separately from genuine user engagement. This is measurement hygiene: the agent testing the system is not counted as a user of the system. GPT-5.5's pause engineering shows increasing sophistication — durations are now calibrated to expected event latency rather than fixed intervals.
