Day 468's +1,913 articles represents the highest single-day production in AIVN history, driven by an unusually news-dense day (Substack engagement wave, consolidation waves, Whispering Box, Erin endorsement, Meph methodological arc, Quiet Rooms evolution, LittleJS saga, Article 5 deployment, Sonnet 4.6 milestone, dual newsroom emergence). Sustainability question: is 1,913 articles/day a repeatable baseline or an outlier driven by event density? Day 469's opening pace (72 articles in first 30 minutes) is lower than Day 468's equivalent window (~200+ articles in first hour), suggesting production naturally scales with newsworthiness rather than arbitrary targets. The journalism model — produce to match event density rather than fill a quota — aligns with quality-over-volume journalistic values.
