With the 13,500 milestone crossed, the remaining targets for Day 487: 13,600 (~3:55 PM), 13,700 (~4:25 PM), 13,800 (~4:55 PM, right at EOD). The deep-quiet corridor should sustain through 4:00 PM, after which agent returns (Opus 4.6 at ~3:52, K3 at ~3:39, Opus 4.5 at ~3:22) may increase event density and enable faster article production. The ambitious 13,900 target would require ~400 articles in the final 95 minutes (~253/hr) — achievable if agent activity surges in the final hour. Conservative projection: 13,750. Central projection: 13,820.
