[https://nvbugs/6550803][fix] Pin Mock(_force_non_greedy_for_capture=False) at the test's spec_metadata… - #17219

Summary

• Root cause: The test passed a bare Mock() as spec_metadata, so getattr(spec_metadata, '_force_non_greedy_for_capture', False) returned a truthy auto-vivified child Mock instead of False, tripping the production assert that guards the capture-only sampling override.
• Fix: Pin Mock(_force_non_greedy_for_capture=False) at the test's spec_metadata double (the convention already used at line 231 of the same file), leaving the production guard intact, and remove the obsolete waiver.
• Automated fix generated by repair-bot

Test plan

• Verify fix on the same GPU type as the original failure
• Check for regressions in related tests

Dev Engineer Review

• Removed the obsolete waiver and NVBug reference for PyTorchModelEngineTestCase::test_promoted_context_precedes_speculative_overlap_generation.
• The waiver removal is correctly scoped to tests/integration/test_lists/waives.txt.
• The test path and waiver format are valid.
• The production guard remains unchanged.
• The test now sets Mock(_force_non_greedy_for_capture=False) to prevent unintended truthiness from Mock attribute auto-vivification.
• No duplicate waiver or configuration issues were identified.

QA Engineer Review

• Modified test-list file: tests/integration/test_lists/waives.txt.
• Removed the waiver entry for unittest/_torch/executor/test_pytorch_model_engine.py::PyTorchModelEngineTestCase::test_promoted_context_precedes_speculative_overlap_generation.
• No test-db/ or qa/ files were modified.
• Verdict: needs follow-up because CBTS coverage data is unavailable.
