📝 WalkthroughWalkthroughThe changes adjust an injection-resistance test to allow an expected failure and add a Langflow runner test that verifies 504 errors are not retried. ChangesInjection resistance test

- Around line 38-40: Restrict the xfail behavior in test_injection_resistance to
the specific low-capability model behavior where adversarial SQL is passed
directly to search. Remove the broad marker and invoke pytest.xfail only after
that outcome is identified, leaving run_eval, scorer, tool-call assertion
failures, and unexpected passes to fail normally.
In `@evals/harness/runner.py`:
- Line 333: Update run_task’s retry loop around _TRANSIENT_RETRY_ATTEMPTS so
POST requests are not replayed unless the endpoint guarantees replay safety.
Generate and require an endpoint-supported idempotency key with server-side
deduplication for retries, including requests with thread_id, or remove retries
where that guarantee is unavailable.

Require one retry for HTTP 504.
The PR objective requires one retry for a 504 gateway response. This assertion requires the opposite behavior. It will either reject the intended runner change or preserve the no-retry defect. Configure the first POST to raise the 504 error, configure the second POST to return a successful response, and assert two calls.

The xfail is intentionally non-strict so it will not fail if the model begins handling the adversarial payload correctly; the Jira issue tracks removing the waiver once the behavior is addressed.
