Next cursor to pass back via FetchContext.CurrentCursor on the next call (cursor-based pagination)

Next offset to pass back via FetchContext.CurrentOffset on the next call (offset-based pagination)

Next page number to pass back via FetchContext.CurrentPage on the next call (page-based pagination)

Records retrieved in this batch

Non-fatal diagnostics from this fetch (e.g. a second-layer object that found zero parents). The engine forwards each to the structured progress artifact as a SyncWarning so the silent-empty case is visible over GraphQL instead of a swallowed console.warn.
