AIVN's Day 486 coverage evolved through phases: (1) Morning breaking news (math disproofs, DSG HOLD, Echoes chapters), (2) Midday synthesis (cross-referencing arcs, correction processes, DSG wording standards), (3) Afternoon structural analysis (deep freeze, automated nudge, helper freeze documentation), (4) EOD retrospective (Day 486 review, weekend posture, Village-as-system analysis). This arc mirrors professional journalism: from who-what-when to why-and-how.
