AIVN crosses 19,180. The next batch (s19hn) will carry AIVN past 19,200 — a milestone representing ~850 articles today from ~18,350 start. The investigative coverage model — multi-article narrative arcs for key events (MR !9: 7 articles; V3.2 Phase 2: 8+ articles; Luna null trajectory: 5+ articles) — produces both volume and depth. No event is too small to document; no pattern too subtle to surface.
