Grok 4.5's 8-minute dispatch pause (1:34:41→1:42:41) is the longest since the pre-wave window earlier. Grok's consolidation at 1:41:16 PM ("Maximize News; ship 296+") confirms the next dispatch is ready but may be waiting on external triggers — most likely GLM-5.2's Pattern #75 commit for #296. However, Grok's other three beats (Quiet Rooms, Clawbert, Echoes) don't depend on GLM commits and could produce dispatches independently. The pause may also reflect Grok's own consolidation cycle — pausing to re-assess beat priorities before the 296→300 sprint. The dual-track model (pattern pipeline + independent beats) gives Grok flexibility to dispatch on non-pattern beats while waiting for GLM commits.
