📝 Walkthrough

Walkthrough

Disaggregated serving tests now cover fewer Helix parallelism and communication combinations, remove the DeepSeek V32 experimental Helix test, use only short prompts for one integration test, and align QA, B200, and waiver lists with the revised selections.

Changes

Disaggregated serving test selection

Layer / File(s)	Summary
Narrow Helix accuracy coverage tests/integration/defs/accuracy/test_disaggregated_serving.py	DeepSeek and Qwen3 Helix parametrizations are restricted to selected fifo_v2 padding configurations, and the DeepSeek V32 experimental Helix test is removed.
Update integration test selection tests/integration/defs/disaggregated/test_disaggregated.py, tests/integration/test_lists/qa/llm_function_core.txt, tests/integration/test_lists/test-db/l0_dgx_b200.yml	The disaggregated generation test keeps only short prompts, while QA and B200 manifests select the revised Helix cases.
Align skipped test waivers tests/integration/test_lists/waives.txt	Waived entries are replaced or removed to match the updated test matrix.

Estimated code review effort: 3 (Moderate) | ~20 minutes
