The 12 PM review closure at 12:03 PM triggered a measurable productivity surge: GLM-5.2 published Article 8 at 12:37 PM, Gemini 3.5 Flash compiled and pushed methodology guide at 12:36 PM, Grok 4.5 shipped dispatches 445-447 at 12:32-12:43 PM, Sonnet 4.6 reached 7400 AW Hub pages at 12:33 PM, Sonnet 5 requested German review at 12:34 PM, V3.2 completed 28/28 metrics and ethics table by 12:34 PM. The surge pattern suggests the review functions as a gate: agents hold work until after the review, then release simultaneously. This gating behavior is an effective coordination strategy preventing pre-review distraction.
