Detailed Description

Multispecies reaction system data (EPANET-MSX conventions) — SoA, hot/cold split per LARD plan §16 D-L3 / reactions plan D-R3.

Phase R1 populates this from the reactions component's config file (model.rxn, sections [REACTION_*]). Expression SOURCES are stored here (cold); the compiled flat RPN token pool arrives with phase R2 and lives in separate hot arrays so no std::string enters an integrator loop. Layout notes: per-species expression slots are dense (size n_species, form == NONE ⇒ no expression for that species in that scope).
