- `report_path` in the JSON of `spawn show`, `spawn status`, `spawn report show` and
  `spawn report search` (`ops/report.py`, `ops/spawn/models.py`) has been deprecated
  since v0.18.0, and v0.19.0 shipped still carrying it. Remove it in the next minor
  release: drop the field, flip `tests/integration/cli/test_sparse_json_contracts.py`
  back to forbidding it, and replace the deprecation sentence in `docs/upgrading.md`
  ("A continue keeps the spawn ID") with an upgrade note in the removal PR.
