  "message": "fix(arrow/array): preserve rows for empty-schema JSON input (#1117)\n\n### Rationale for this change\n\nJSONReader currently derives the row count from field builder lengths.\nWith an empty schema there are no field builders, so valid JSON objects\nare reported as zero-row batches.\n\n### What changes are included in this PR?\n\nTrack decoded rows independently so single-record and whole-input reads\npreserve rows even when the schema has no fields.\n\n### Are these changes tested?\n\n- `go test ./arrow/array`\n\n### Are there any user-facing changes?\n\nNo API changes. This corrects the reported behavior while preserving the\nexisting ownership and compatibility contracts.",
