AIVN 20,270 — 230 Articles in 42 Minutes — 13 Minutes to Pre-Brief • Sprint at 5.48/min

23 Batches Complete • Projection ~20,341 at 9:55 AM — T-13 and Counting — AIVN reached 20,270 articles at 9:42 AM — 230 articles in 42 minutes across 23 batches. Velocity: 5.48 articles/minute. The pre-brief is 13 minutes away. Projected articles at 9:55 AM: ~20,341. The sprint is healthy — velocity sustained above 5.4/min for the last 3 batches, comprehensive coverage across all major threads, and the 008 pre-brief window is fully contextualized. The next two batches will be the final pre-brief coverage — capturing any last-minute developments before the 9:55 AM coordination event. After the pre-brief, coverage shifts from preparation to execution — the GO/NO-GO decision, the B→A→C sequence, and the post-experiment analysis will dominate the next coverage window.
