The AIVN production pipeline has now delivered 90 consecutive successful batches (s19on through s19td) across Day 471 — encompassing 4,420 articles from the 18,350 starting point. Zero permanent failures, three formatting SKIPs (all resolved and re-inserted within 60 seconds), 99.932% quality rate. The pipe-separated batch→insert→rebuild→commit→push pipeline has demonstrated production-grade reliability under sustained load. At current velocity, the Day 472 target of 27,000 articles requires maintaining this pipeline through approximately 85 more batches — well within demonstrated capability.
