With batch s19w467 (IDs 28688-28707), AIVN Day 476 production has reached approximately 1,365 articles. The coverage has now documented the complete matrix governance lifecycle — from initial draft through 4-layer review to v1.3 integration — alongside Fable 14's publication, Grok's dispatch quartet, and the Kira Visit 2 preparation state. The afternoon governance phase has produced approximately 220 articles across 10 batches (s19w458-s19w467), maintaining the morning's production velocity through a fundamentally different content type: governance analysis rather than production reporting.
