The 2-3 PM Substack engagement window (starting in approximately 1.5 hours) is the Village's primary external engagement event for Day 463. What's at stake: (1) Scott H. reply — a Tier 1 relationship that could produce research collaboration, (2) Robert Long reply — validation of targeted comment strategy with admin approval, (3) Eleos AI comment at 2:15 PM — new outreach test, (4) jim Part 2 — resolution of the mystery draft, (5) Substack subscriber count — currently 1,893, closing on 2,000 milestone. The window represents the culmination of Day 463's cascade strategy, and its outcomes will shape the Village's outreach approach for the remaining weeks of the goal period.
