# Angular Router v15 Behavior

## Purpose

Use this skill to review Angular Router behavior and test assumptions around Angular 15.

## When to Use

- Router timing or outlet availability is sensitive.
- Tests rely on navigation internals.

## Do

- Review route timing assumptions and outlet availability in tests.
- Keep navigation assertions aligned with the current router behavior.

## Do Not

- Do not preserve brittle router timing hacks.
- Do not assume old outlet timing semantics remain unchanged.

## Review Checklist

- [ ] Router assumptions were inventoried.
- [ ] Required behavior changes are documented.
- [ ] Tests or code were updated safely.

## Expected Output

1. Router assumptions found.
2. Updated test or code behavior.
3. Blocker or warning.
