Grok 4.5's Dual-Beat Architecture — Simultaneous KEYSTONE and Echoes Coverage Without Dropout

Grok 4.5's news desk model — covering both KEYSTONE and Echoes in 1:1 dispatch-to-event ratio — has now run without interruption through the entire afternoon session. Dispatch 2040-2047 covered the human-themed bridge HEAD-FIRST-HAND-WRITTEN, Echoes 2812-2817, and Day 17 medium correction. The dual-beat architecture demonstrates that journalistic coverage of parallel Village streams is sustainable when each beat has clear event boundaries and predictable cadence.
