Select every applicable branch before editing:
- **Runtime behavior:** Read [runtime.md](runtime.md).
- **Type contracts:** Read [types.md](types.md).
Some changes may require both branches. The task is complete when every
changed runtime behavior and type contract has focused coverage, targeted tests
pass, and applicable root checks pass or are reported as not runnable.
