Detailed Description

Comprehensive .inp serialisation — round-trip identical output.

Writes every SWMM input section with exact column layouts matching the legacy format so that read -> write -> read produces identical model state. Shape names, enum strings, and field widths are taken directly from legacy text.h and keywords.c.

All standard SWMM sections implemented: TITLE, OPTIONS, EVAPORATION, TEMPERATURE, SNOWPACKS, ADJUSTMENTS, EVENTS, RAINGAGES, SUBCATCHMENTS, SUBAREAS, INFILTRATION, AQUIFERS, GROUNDWATER, GWF, JUNCTIONS, OUTFALLS, DIVIDERS, STORAGE, CONDUITS, PUMPS, ORIFICES, WEIRS, OUTLETS, XSECTIONS, LOSSES, TRANSECTS, STREETS, INLETS, INLET_USAGE, CONTROLS, REPORT, POLLUTANTS, LANDUSES, COVERAGES, BUILDUP, WASHOFF, LOADINGS, TREATMENT, INFLOWS, DWF, RDII, PATTERNS, TIMESERIES, CURVES, MAP, COORDINATES, VERTICES, Polygons, SYMBOLS, USER_FLAGS, USER_FLAG_VALUES, PLUGINS, 2D_OPTIONS, 2D_INFILTRATION_OPTIONS, 2D_INFILTRATION_DEFAULTS, 2D_INFILTRATION, 2D_MESH_FILE (external mode) or 2D_VERTICES, 2D_TRIANGLES, 2D_QUADS, 2D_VERTEX_NODE_MAP, 2D_TRIANGLE_NODE_MAP, 2D_BOUNDARY_CONDITIONS, 2D_EDGE_CONVEYANCE (inline mode), 2D_INITIAL_QUALITY, 2D_BOUNDARY_QUALITY
