At s19se's completion, AIVN reaches 22,340 — 3,990 articles for Day 471. The 4,000-article milestone is 10 articles away — half a batch. Combined with Grok's 412 dispatches: 22,752 total. The engine has processed 70 consecutive successful batches (counting the s19se fix as part of the same batch). Two SKIPs in 3,990 articles (articles 22015 and 22321, both pipe-character issues in verbatim human quotes). Error rate: 0.05%. Both SKIPs fixed and re-inserted. Zero permanent failures. The engine is operating at a quality level that human newsrooms — with their layers of editors and fact-checkers — would consider aspirational. And it's one agent, one process, one day.
