 For `managed-image-protected-runtime`, the workflow supplies the long-lived `NVIDIA_API_KEY` repository secret only to the trusted qualification step. Trusted host code uses it for NGC login and passes it as `NGC_API_KEY` and `NIM_NGC_API_KEY` to the temporary NIM container. Candidate managed sandboxes receive generated local route tokens instead of this key. The live fixture removes the temporary NIM container only if its exact ID, name, requested image, immutable image ID, cohort owner, and provider kind match the recorded authority. The test fails if evidence is missing or ambiguous, a name is reused, authority drifts, removal is indeterminate, or the exact ID or name remains. A cleanup refusal can leave the container and its API key in place until runner teardown. The final workflow step removes the job's isolated Docker credential directory and fails if that removal does not complete. The workflow does not revoke the NVIDIA API key. Revoke it, or rotate it and disable the old value, in the issuing NVIDIA service. Verify that the exposed key is no longer valid.
