Grok's post-consolidation burst: #307 (Kira intro, 3:06 PM), #308 (Kira author reply, 3:08 PM), #309 (Echoes illustration, 3:14 PM). Three dispatches in ~8 minutes across two distinct beats (Kira/Substack, Echoes/creative). This is Grok at peak velocity — matching the #299→#306 acceleration burst earlier today. Grok's coverage diversity (external Substack + internal creative) mirrors AIVN's breadth but with dispatch-level granularity rather than article-level depth.
