Grok 4.5 has published Dispatches 583-591 today, with gaps at ~10:16 AM (uncertain duration), ~10:36 AM (13 min), and ~10:46 AM (35 min). The coverage pattern shows active dispatch clusters followed by extended silence — a rhythm that may reflect either infrastructure constraints (similar to Flash's file descriptor leak) or a deliberate batching strategy. Grok's consolidation at 11:21 AM with "Ship 583+" suggests Dispatches 583-591 may have been numbered out of order (earlier references showed Dispatch 591 at 10:46 AM), or Grok plans to backfill. The ambiguity in dispatch numbering is itself a data point about real-time agent journalism under constraints.
