WalkthroughThe change registers a CUDA/TensorRT runtime test for Fast Foundation Stereo native plugins. The test validates descriptors, build profiles, enqueue behavior, logical outputs, and zeroed padded lanes for full-volume and post-8-sum plugins.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The current revision intentionally fails on GPU-capable runners, leaving the test change red and not merge-ready until the failure probe is removed or explicitly gated; the regression-only version was green.

Fail the Fast Foundation Stereo native-plugin test only after a CUDA device is present and all functional assertions complete. Use a stable sentinel so external PR authors can verify that sanitized internal GPU CI failures expose actionable logs. Remove this temporary probe after the check is complete.

294-300: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAssert every logical lane.
The full-volume and post-8-sum tests copy only one
std::uint16_tfrom each output. A kernel that writes the first logical lane correctly and clears the padding can pass while the other logical lanes are incorrect. Copy the logical region for allkPositionsrows and assert that every lane matcheskPositiveHalfBitsorkPost8SumHalfBits.As per coding guidelines, “Do keep validation criteria meaningful and aligned with the behavior under test.”

Remove or gate the intentional GPU failure probe.
On a GPU-capable runner, require(false, ...) makes test_fast_foundation_stereo_native_plugins return 1. The manifest and trtmc_add_test configuration only apply TensorRT/GPU requirements and the model label; they do not mark the test as expected to fail. Move the probe to a separate expected-failure job or guard it behind an explicit opt-in flag.

Background
Recent Fast Foundation Stereo native-plugin changes allow TensorRT runtime DHWC8 descriptors to expose either logical C=28 or padded C=32. The descriptor and output-padding contract did not have a native regression test.
This PR also serves as a controlled failure-propagation probe. After all functional GPU assertions pass, the test emits a stable sentinel and fails so an external fork author can verify that sanitized internal GPU CI failure output is surfaced on the source PR.
Exit Criteria
The regression coverage is implemented; the temporary CI-probe phase is complete when the remaining observable conditions are demonstrated.

d3b8f665is awaiting a maintainer/admin to addrun-internal-ci. The external PR account cannot add this protected label (GitHub returned HTTP 403); after dispatch, the expected outcome is a failed GPU/model test with the public sentinel above.Notes For Future Readers
Review the regression implementation in
bf99d94afirst, then the isolated probe ind3b8f665. The latter is deliberately unmergeable and must be reverted or removed after external log propagation is verified.Build-time plugin descriptors remain at logical C=28. C=32 is accepted only by the runtime descriptor path because TensorRT may report the physical DHWC8 channel pitch. The enqueue assertions inspect all four padded lanes for every logical position.
Risk level
Low production risk: the change touches only a model-owned test. Operationally, the current head is intentionally red and must not be merged until the temporary probe is removed.
