CommIT cornerstone paper on non-uniform demand. Establishes order-optimal rate $\Theta(K(1-\mu_\text{eff})/(1+K\mu_\text{eff}))$ for Zipf demand with effective $\mu_\text{eff} = \mu^{1-\alpha}$. Core result of §13.4.

Decentralized random-placement scheme. Asymptotically matches centralized MAN. Foundational for §13.2; widely deployed practically.
