Summary:

The ReactNativeNewArchitectureFeatureFlags.enableFabricRenderer() flag is being deleted; it always returns true on the canary release stage. The default initializer of ReactDelegate.isFabricEnabled reads the flag — change it to true directly.

The field itself is preserved because it can be set by the deprecated (activity, reactNativeHost, appKey, launchOptions, fabricEnabled) constructor that lets callers override the default.

Behavior is unchanged.

Summary:

The `enableFabricRenderer()` flag is being deleted; it always returns true on the canary release stage. In `loadWithFeatureFlags`, replace both `featureFlags.enableFabricRenderer()` reads with the literal `true` for `privateFabricEnabled` and `privateConcurrentReactEnabled`.

Behavior is unchanged.

Summary:

The `ReactNativeNewArchitectureFeatureFlags.enableFabricRenderer()` flag is being deleted; it always returns true on the canary release stage. In `createRootView`, inline `setIsFabric(true)` and remove the now-unused import.

Behavior is unchanged.

Summary:

The `ReactNativeNewArchitectureFeatureFlags.enableFabricRenderer()` flag is being deleted; it always returns true on the canary release stage. The DEBUG-only `assertCondition(enableFabricRenderer(), ...)` check in `getOrCreateStartTask` becomes tautological — delete it.

The other DEBUG assertions in the same block (`enableBridgelessArchitecture`, `useTurboModules`) are unaffected.

Behavior is unchanged.

Summary:

The `ReactNativeNewArchitectureFeatureFlags.enableFabricRenderer()` flag is being deleted; it always returns true on the canary release stage. The default body of `ReactActivityDelegate.isFabricEnabled()` reads the flag — change it to `return true` directly.

The method itself is preserved because it is a polymorphic `protected` hook that subclasses (e.g., `DefaultReactActivityDelegate`) override to provide per-activity behavior.

Behavior is unchanged.
