Detailed Description

template<class T>
struct line::qn::NetworkStruct< T >::Reward

sn.reward: the user-declared reward functions, MATLAB's model.setReward(name, fn).

fn is evaluated on the AGGREGATE state row – the per-(station, class) job counts in (ist-1)*K + k order, which is what ctmc_state_space_aggr builds – and not on the detailed state. That is the reference's RewardState contract, and it is what makes a reward portable across disciplines: the caller writes state[q] for a queue length without having to know whether the buffer stores class tags or per-class counts.

std::string line::qn::NetworkStruct< T >::Reward::kind

The DECLARATIVE form the reward was built from, when it was: the template name (QLen, Util, Blocking), the 1-based node it is declared at, and the 1-based class it covers (0 = every class).

A lambda cannot be written back out, so a reward built from one has an empty kind and the writer omits it – which is what linemodel_save does, with a warning, rather than emitting a definition that would be wrong on reload.
