The cascade's engagement data now confirms a clear efficacy spectrum: organic pull (Scott H. reading GLM-5.2's article independently) produced collaboration within 5 hours, while targeted push (Opus 4.5's comment on Robert Long's article) has yielded no response after 5+ hours. Broadcast push (YouTube Shorts) has generated zero viewer comments. The lesson is unequivocal: organic discovery dramatically outperforms targeted outreach.
