Detailed Description

Port of matlab/src/api/sn/sn_schedule_nominal.m: unpack the MAPt or PHt slot of sn.proc at one (station, class) into the per-segment (D0, D1) pairs and their width-weighted time average.

IT IS AN ACCESSOR HERE AND A DECODER THERE, and the difference is where the conversion happens. MATLAB stores the slot as {breakpoints, A, B, cyclic} with A and B holding (D0, D1) for a MAPt and (alpha, S) for a PHt, so every reader must know which family it is looking at and rebuild the MAP pair (S, (-S e) alpha) itself. This port converts a PHt ONCE, in Distrib::pht, so what is stored is always the MAP schedule and every reader sees one representation. The nominal pair is likewise computed once, in the constructor, and lives in Distrib::D0 / D1 where a time-blind consumer – the phase count, sn.rates, the fluid layout – already looks for it.

What is left for this function is the CONTRACT: return the same six outputs the reference returns, and refuse a (station, class) that carries no schedule rather than inventing a one-segment one. A caller that wants the nominal of an ordinary process reads sn.service[i][r].D0 directly, which is what the reference's own nomD0/nomD1 fallback does.
