**Note on benchmark variance:** These results were collected on a non-isolated machine without CPU frequency pinning. Small variances of ±5% on non-bw=0 paths (particularly `mandatory/optional, no NULLs`) are consistent with measurement noise rather than real regressions — the changes to those code paths are additive only. The `#[cold]` annotation on the terminal path (PR #9787) was added specifically to prevent icache pressure on the non-terminal hot path. Happy to share raw criterion output or rerun on a more controlled setup if helpful. -- This is an automated message from the Apache Git Service.
