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](runtime.md).
- **Type performance:** Read [types.md](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.
