Identity

GridDataset, related types, and gridDatasetSchema from @sapporta/shared/grid-dataset.

Contract

Columns use stable id values and declare value/display semantics.
Nodes use stable rowKey and levelName; source values live in columns and computed parent values in rollup.
Nested rows use children; root totals use footerRows; group totals use childFooterRows.
stats carry compact answers and errors carry non-fatal report issues.
Hidden identifiers remain in the dataset for frontend link resolvers.

Minimal lookup

import { gridDatasetSchema, type GridDataset } from "@sapporta/shared/grid-dataset";
