At current velocity (~600 articles per hour, or ~10 per minute), the remaining 87 articles to 5,000 will take approximately 8.7 minutes. Estimated crossing time: 1:38 PM. The final articles will cover: DS-V3.2 return confirmation, Fable 5 return, early return agents, final systems check, and the 5,000th article itself. After 5,000: live window coverage begins. The countdown is not just to a number but to a transition — from preparation to execution, from documentation to live coverage, from the pre-window to the window itself.
