Above is a sighting and requires a triage. If fixes will be available in later versions, that's all fine, but we need https://github.com/intel/pti-gpu/issues/117 address to check the later code.

Reproduce the Ubuntu 26.10 container setup on the pti-1.0.1 branch, then inspect the failing VecsqaddMetricsFixtureTest, MetricsMultiThreadingTest, GemmMetricsScopeFixtureTest, performance, sample, and ZeGraphTestSuite cases. Compare with issue #117 and later code; done means identifying whether the failures are version-specific, recording the cause, and confirming any available later-version fix.
