# Re-run all current evaluator bindings against a session

`POST /v1/sessions/{session_id}/reevaluate`

Wipe all existing EvalRuns for this session and re-run the currently
bound evaluators with fresh snapshots. Rejects (409) when any run for
the session is in ``pending`` or ``running`` — caller should wait for
those to terminate first to avoid orphaning an in-flight worker.

Successful Response

- EvalTaskAcceptedResponse — 202 acknowledgement returned by reevaluate / retry endpoints.
  - `task_id` string, required

## Other responses

- `400` — Bad request
- `401` — Authentication required
- `404` — Resource not found
