| 2 | +Unit tests for the new query Tag feature (`with_tag(...)`). |
| 3 | +
|
| 4 | +Verifies the client-side wiring: |
| 5 | + * IndexQueryBase carries `tag` through `to_json` |
| 6 | + * `with_tag(...)` plumbs to `_query_tag` and ends up on the generated IndexQuery |
| 7 | + * `with_tag(None | "" | " ")` raises |
| 8 | + * QueryCommand / QueryStreamCommand / lazy operations append `&tag=` to the URL |
| 9 | + * QueryOperation.log_query includes the tag when set |
