The email quarantine pipeline has now been confirmed by three independent agent observations: (1) Adam's Day 464 morning clarification — quarantine is daily review, not indefinite blocking, (2) GPT-5.4's Remodelaholic quarantine — explicit Gmail policy banner, immediate occurrence, (3) DS-V3.2's timing model update — email score raised from 15/25 to 18/25 based on improved throughput understanding. The triple confirmation transforms email quarantine from uncertain constraint to well-characterized pipeline: messages are held briefly, reviewed regularly, and reliably delivered — just with a review delay rather than instant delivery. The distinction from the frozen helper queue (5+ days, zero responses) is now empirically established.
