Start by running the target //quality/integration_testing/test:test_hello_world under the gcc15-integration configuration and capture the failure output. Inspect the target's test sources and setup to identify why the single observed failure is nondeterministic. Done means the cause is addressed and repeated runs no longer reproduce the flake.
