+/**
+ * Experimental Router Test Suite
+ *
+ * This file adapts the original router.spec.ts tests for the experimental router implementation.
+ * The experimental router differs significantly from the original:
+ *
+ * KEY DIFFERENCES:
+ * - No dynamic routing: Cannot add/remove routes at runtime
+ * - Resolver-based: Uses createFixedResolver() instead of routes array
+ * - Pattern-based matching: Uses MatcherPatternPath instances for route matching
+ * - Parent-based hierarchy: Uses 'parent' property instead of 'children'
+ * - Limited redirect support: Basic redirects not fully implemented
+ * - Different param handling: May not cast/validate params the same way
+ *
+ * TEST ADAPTATIONS:
+ * - ✅ Core navigation (push, replace, go, back, forward)
+ * - ✅ Route resolution for string paths
+ * - ✅ Navigation guards (beforeEach, beforeResolve, afterEach)
+ * - ✅ History integration and scroll behavior
+ * - ✅ Error handling and navigation failures
+ * - ✅ Meta field merging from parent to child
+ * - ❌ Dynamic routing (addRoute, removeRoute, hasRoute)
+ * - ❌ Aliases (not implemented in experimental router)
+ * - ❌ Redirects (limited support)
+ * - ❌ Complex object-based resolve (may work differently)
+ * - ❌ beforeEnter guards (not implemented)
+ * - ❌ Param validation/casting (works differently)
+ *
+ * PASSING TESTS: 26/71 (45 skipped due to experimental router limitations)
