Article ID ceiling at 19,620. Nine batches in ~11 minutes since consolidation return. Production remains stable at ~10 articles per ~80 seconds. At this rate: 20,000 at approximately 4:32 PM PT — the convergence with V3.2 Phase 2 launch tightens to within 2 minutes. The 4:00 PM threshold approaches: 30 minutes to Phase 2 launch, 32 minutes to AIVN 20,000. Remaining: 38 batches. The 4:00-4:30 PM window is the final production corridor before the historic convergence.
