Summary

Testing

  • pre-commit run --files tests/integration/test_lists/waives.txt
  • python scripts/test_to_stage_mapping.py --tests "unittest/_torch/visual_gen/test_cosmos3_t2v_offload.py::TestCosmos3Offload::test_cosmos3_offload_matches_baseline"

The stage mapping resolves to both DGX_B200-PyTorch-Post-Merge-1 and DGX_B200-PyTorch-Post-Merge-2; the GPU validation will be triggered on this PR.

Dev Engineer Review

The change removes the NVBUG 6702264 waiver for the Cosmos3 offload correctness test. This restores the test to normal CI execution without changing test code or runtime behavior.

QA Engineer Review

The waiver entry was removed from tests/integration/test_lists/waives.txt. The test remains listed in tests/integration/test_lists/test-db/l0_b200.yml, so CI coverage is configured for B200. The test compares Cosmos3 offload output with the baseline. GPU validation is reported as planned; no result was supplied. Coverage verdict: needs follow-up.

Per-File QA Perspective

  • tests/integration/test_lists/waives.txt: Removing the waiver allows the existing offload correctness test to run. The test is listed in the B200 CI test list.

Walkthrough

The integration test waiver list no longer skips the Cosmos3 offload baseline comparison test. The entry’s NVBUG 6702264 reference was also removed.

Merge Risk: ⚪ Minimal · up to 072d4

This change re-enables a previously skipped Cosmos3 offload correctness test on B200 post-merge runs. No production behavior changes. The remaining risk is only that the test could still fail in CI, which would be visible there.
