+## List UX requirements (must be generated)
+
+- Lists must include **filtering UI** via `filters` prop on `List` and an explicit actions toolbar with:
+  - `FilterButton` (so non-`alwaysOn` filters are discoverable)
+  - `CreateButton`
+  - `ExportButton`
+- Lists must include a **default sort** (`sort={{ field: "...", order: "ASC|DESC" }}`) appropriate for the entity.
+
+## Reference selection UX (must be generated)
+
+- For foreign keys (`ReferenceInput`) in Create/Edit forms, prefer `AutocompleteInput` over `SelectInput` to support search.
+- Autocomplete must send search text to backend using `filterToQuery={(searchText) => ({ q: searchText })}`.
+- Option text must include a **code** (or business identifier) and a name when available, e.g. `CODE — NAME`.
+
+## Enum filters (must be generated)
+
+- For enum fields in **list filters**, use:
+  - `SelectInput` for single-select filters
+  - `SelectArrayInput` for multi-select filters when users need to filter by multiple enum values (e.g. Status).
