Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Focus traversal | Choose focus traversal when the design problem is the user's sequential path through focusable elements and dynamic state changes. | The sequential focus path follows DOM and reading order unless a well-tested component-specific model declares a different internal focus contract. | Supports tabindex behavior in sequential focus navigation. |
