FLAKY - The following job failed but was likely due to flakiness present on trunk:

• Continuous Benchmark (PR) / CPU Pytest benchmark (gh) (similar failure)

BROKEN TRUNK - The following jobs failed but was present on the merge base:

👉 Rebase onto the `viable/strict` branch to avoid these failures

• Continuous Benchmark / CPU Pytest benchmark (gh) (trunk failure)
• Continuous Benchmark / GPU Pytest benchmark (gh) (trunk failure)
  Process completed with exit code 4.
