Closing — temporary CI sample for #2473 flake re-validation. Conclusion (revert was premature; optimization restored) is recorded on #2473.

[pranaygp]

Behavior-neutral (comment-only) baseline for Windows-unit flake-rate measurement vs the synchronous consume-drain optimization. Runtime identical to main. Do not merge.

Closing — temporary CI sample for #2473 flake re-validation. Conclusion (revert was premature; optimization restored) is recorded on #2473.

[pranaygp]

Behavior-neutral (comment-only) baseline for Windows-unit flake-rate measurement vs the synchronous consume-drain optimization. Runtime identical to main. Do not merge.

Column Definitions

• Workflow Time: Runtime reported by workflow (completedAt - createdAt) - primary metric

Closing — temporary CI sample for #2473 flake re-validation. Conclusion (revert was premature; optimization restored) is recorded on #2473.

[pranaygp]

Behavior-neutral (comment-only) baseline for Windows-unit flake-rate measurement vs the synchronous consume-drain optimization. Runtime identical to main. Do not merge.

Closing — temporary CI sample for #2473 flake re-validation. Conclusion (revert was premature; optimization restored) is recorded on #2473.

[pranaygp]

Behavior-neutral (comment-only) baseline for Windows-unit flake-rate measurement vs the synchronous consume-drain optimization. Runtime identical to main. Do not merge.
