name: performance-analysis description: Performance analysis. Use for runtime throughput or latency benchmarks, TypeScript compiler cost, performance regressions, comparison harnesses, or thresholds.

Validate correctness with focused tests before measuring. Compare the same focused operation and environment across revisions; a single unpaired run is not evidence of improvement.

Select every applicable branch:

• Runtime performance: Read runtime.md.
• Type performance: Read types.md.

The task is complete when every selected branch meets its measurement and reporting criteria and applicable root checks pass or are reported as not runnable.
