## Title

    Use sweep names that cannot collide after path construction (source-backed, not verified by KFA)

## Body

    Source-backed, not verified by KFA: the reporter's controlled reproducer ran both benchmarks and returned completed counts [10, 20] when control names were distinct, whereas colliding names such as experiment/a and experiment_a reused the first result (https://github.com/vllm-project/vllm/issues/60794). The reporter also notes that names unique per axis can collide once joined, so check the final joined result paths, not just raw names. This is a mitigation inferred from the report, not a confirmed fix or maintainer guidance. Do not delete result directories on this basis without your own review.
