The important schemas are frontend DesignerState and backend geometry/export request models. There is no separate public Project, Layout, or Export manifest schema.
envelope: unit system, outline points, handle metadata, base height, and geometry metadata.layout: packing, spacing, clearances, case settings, panelized/bossed options, spacers, and layer gaps.cells: selected cell profile plus custom-cell physical and electrical fields.cellAssignments: painted cell groups, generated plan metadata, and connection metrics.caseParts: lids, cutouts, mounts, imported parts, and import presets.busbars: layer definitions, group visibility, fold metadata, side flips, and manual bridge data.CaseExportRequest combines outline/height, case mode, wall/chamfer settings, lids, panels, cutouts, mounts, requested formats, DXF, breakdown, and slicing options.SpacerExportRequest includes scene geometry, spacer settings, requested formats, and archive/slicing preferences.BusbarExportRequest includes scene-derived segments, busbar layers, fold IDs, side flips, material settings, and split/export format flags.SeriesPlanRequest includes scene data plus target series/parallel intent and culling options.
