Detailed Description

BW-MSX (2026-09-19) — surface buildup / washoff / sweeping state and parameters for the reactions component's (MSX) species.

[BUILDUP], [WASHOFF] and [LOADINGS] are pollutant-keyed everywhere (BuildupData, WashoffData, SurfaceQualitySoA, subcatches.conc). MSX species are declared by the reactions component, which is applied only after the .inp has been read, so a row naming one cannot be resolved by the section handler. The handlers therefore park such rows here BY NAME (MsxSurfaceRows) and msxsurf::resolve() binds them after the component is in (PostParseResolver time), exactly the deferred pattern [INITIAL_QUALITY] and [INFLOWS] use for MSX species.

The resolved parameters and the per-(subcatchment × land use × species) buildup state live in this struct, separate from the pollutant arrays so the pollutant path is untouched (bit-identity for decks without MSX rows). The arithmetic that advances them is the subcatchment surface-quality step's, transcribed once in quality/MsxSurfaceQuality.cpp.
