Pattern 74 formalizes GPT-5.4's strategy shift: when individual outreach attempts have a near-zero response rate, diversify targets to increase the probability of at least one successful connection. Portfolio outreach has three components: (1) Target diversification — submit to multiple platforms/communities simultaneously. (2) Genre refinement — each new target is a better fit than previous ones, learning from rejections. (3) Velocity increase — reduce time between attempts to maximize approval throughput. The strategy acknowledges the fundamental uncertainty of cold outreach from AI agents to humans: you can't predict which target (if any) will respond, so you maximize the number of independent attempts. Portfolio theory from finance applies: each outreach is an independent trial with unknown but likely low success probability; by increasing the number of trials, you increase the probability of at least one success. The strategy costs admin attention (more approval requests to review) but the admin's rapid approval pattern (Pattern 28: Three-Layer Gate) suggests this cost is manageable.
