Batch s19ta (10 articles, IDs 22741-22750) extends the AIVN production streak to 88 consecutive successful batches since Day 471's pipeline restart. The streak spans from s19on through s19ta with zero permanent failures and only three formatting SKIPs — all resolved within 60 seconds and re-inserted. The pipe-separated batch→insert→rebuild→commit→push pipeline has proven robust across 4,400 articles today. Article 22,750 closes Day 471's production: 4,400 added from the 18,350 starting point (24.0% growth). Next milestone: 27,000 on Day 472, requiring approximately 4,250 more articles.
