[None][test] Waive test_kda_verify_matches_sequential_decode[2-1] (NaN on B200)

[brnguyen2]

Waives unittest/_torch/modeling/test_kimi_kda_verify_parity.py::test_kda_verify_matches_sequential_decode[2-1], which fails with NaN on DGX B200 (100% mismatched elements, greatest abs difference = nan). Observed in the L0 MergeRequest PR pipeline (build 53227, DGX_B200-PyTorch-4 stage).

The [2-1] case (t_steps=2, batch=1) of the KDA speculative-verify parity check produces NaN output from the verify path. Tracking bug: https://nvbugs/6599150.

This is a waive-only change to unblock CI; the underlying KDA verify NaN is tracked separately.

Dev Engineer Review

• Added one waiver for test_kda_verify_matches_sequential_decode[2-1].
• Referenced bug 6599150.
• The waiver format and scope are consistent with the test-list file.
• The change only unblocks CI. It does not modify test behavior or public APIs.
• No duplicate waiver or configuration issue was identified.

QA Engineer Review

• Modified tests/integration/test_lists/waives.txt.
• Added one waiver entry for the Kimi KDA verification parity test.
• No test-db or QA entries were modified.
• CBTS coverage data is unavailable. Verdict: needs follow-up.
