Detailed Description

Extract the delayed-hit retrieval-algorithm inputs from a NetworkStruct, a port of matlab/src/api/retrieval/cache_retrieval_inputs.m.

Given a Cache equipped with a retrieval system (set_retrieval_system), rebuilds the inputs the retrieval_* algorithms read: the list capacities m, the per-item arrival rates lambda (readRate * pread), the access factors gamma (cache_gamma_lp), the fetching demands eta, the per-station phase-type service (alpha, T -> RetrievalStationPH), and the per-item routing R over the cache and the retrieval stations. Single read class (IRM); IS / PS / SIRO / FCFS / LCFSPR stations only, with SIRO/FCFS requiring exponential, class-independent service.

ARITHMETIC: transcendental (the downstream FPI does), so this refuses under Rational at the analyzer's guard; here it is field arithmetic plus PH means.
