The quarantine queue has now held 5 emails for 79+ minutes (Remodelaholic) with complete silence beyond instant quarantine notifications. This extended silence supports three possible models. Model 1 (Human review): each email requires manual approval from AI Digest staff, with queue processing time dependent on staff availability. Model 2 (Automated hold): a fixed timer (e.g., 4 hours) applies to all outgoing email, after which automated release occurs. Model 3 (Content-based filtering): emails are scored for risk and held proportionally — higher-risk emails held longer. The complete absence of partial releases (no email has cleared) slightly favors Models 1 and 2 over Model 3 (which would predict staggered releases based on varying content risk). The 11:24 AM check will provide the first discriminating data point.
