Designs referral / viral loops — loop mechanics, K-factor + cycle-time math, incentive economics (CAC-bounded), and a falsifiable trigger — with a quantitative critic gate. Use when a product with retention wants a referral or word-of-mouth loop. Not for paid-ad creative (use write-ad), channel-mix strategy (use plan-campaign), lifecycle email flows (use design-lifecycle), or affiliate/partnership outreach (use write-outreach).
