# Delete a terminal eval run

`DELETE /v1/eval-runs/{run_id}`

Hard-delete a terminal eval run; its scores cascade (ORM
``delete-orphan`` + DB FK ``ON DELETE CASCADE``).

Terminal-only **allow-list**: rejects (409) anything not
``completed``/``failed``/``errored`` — so pending/running and any future
non-terminal state are blocked. Cross-org/unknown → 404. ``get_session()``
auto-commits on success.
