%
% Analyzer for a CLOSED integrated cache-queueing model whose Cache node has a
% delayed-hit retrieval system. Delegates to da_cacheqn_retrieval, which relabels
% the cache as a class switch and lets the finite-population coalescing emerge from
% the closed AMVA via a load-dependent fetch station. Returns the true cache
% hit/miss probabilities (hit = P(item cached), miss = 1 - hit); the delayed-hit
% fraction is folded into miss (delayedprob = 0).
