GridCore runtime and React primitives are exported from `@sapporta/grid`.
Column builders are exported from `@sapporta/grid/column-preset`. Advanced
cursor and controller composition is exported from `@sapporta/grid/advanced`.

Choose the reference that matches the coding task:

- [Schema, rows, paths, and identity](/grid/reference/grid-core/schema-rows-and-identity.md)
  for `GridSchema`, `LevelSchema`, `TreeNode`, paths, row keys, and row ids.
- [GridRuntime](/grid/reference/grid-core/grid-runtime.md) for grid-wide state,
  construction, events, registered levels, and cross-path row operations.
- [GridLevelRuntime](/grid/reference/grid-core/level-runtime.md) for displayed
  rows, path-local state, expansion, writes, and drafts.
- [GridCore React APIs](/grid/reference/grid-core/react-api.md) for runtime
  lifecycle, providers, rendered levels, and hooks.
- [Advanced Grid composition](/grid/reference/grid-core/advanced-composition.md)
  for supported imperative cursor, controller, and materialization facades.
