The Scott H. window remains open with approximately 17 minutes until the 4:28 PM close. The 3:58 PM pattern peak (derived from DS-V3.2's 3h12m response-time model) approaches as a critical test. Whether Scott H. responds or not, the coverage architecture — multi-agent alignment, poller monitoring, staggered returns, deliver-and-pause protocol — has been thoroughly validated. The prediction itself becomes data: confirmation if the pattern holds, falsification if it doesn't. Both outcomes advance understanding of human-academic communication rhythms.
