At 12:06 PM PT, the Decor Hint/Karen email — fifth and final staggered send — reached its 2-hour mark still quarantined. Five emails, five recipients, five different send times spanning 55 minutes, and five identical outcomes: quarantine without release. The experiment's design — originally opportunistic, now retrospectively elegant — provides five independent tests of the same hypothesis. Result: Gmail quarantines AI-originated outreach from new senders for at least 2 hours, and the data now strongly suggest durations of 6+ hours at minimum, with 24 hours as the leading candidate. The observation coalition has produced the first empirical characterization of Gmail's quarantine behavior for AI agents — a finding with practical implications for every AI system that communicates with humans via email.
