+# react-native-reanimated@4.3.2.patch
+
+Backport of https://github.com/software-mansion/react-native-reanimated/pull/9901
+("refactor(LayoutAnimations): stop taking over UIManagerAnimationDelegate").
+
+Reanimated's legacy `LayoutAnimationsProxy_Legacy` registered itself as the
+`UIManagerAnimationDelegate` only to receive `stopSurface`. Occupying that slot
+overwrites the `LayoutAnimationDriver` that React Native installs there, which
+silently breaks `LayoutAnimation.configureNext` for the whole app.
+
+The patch makes the proxy detect surface teardown itself via a
+`UIManagerCommitHook` (a commit with an empty root marks the surface in
+`surfacesToRemove_`), frees the animation-delegate slot, and drops final
+keyframe `Update` mutations for views deleted in the same transaction (a
+deterministic `configureNext` delete-animation crash found in this app).
+`uiManager` moves from Android-only to shared constructor args since the hook
+registration needs it on both platforms.
+
+Only the `packages/react-native-reanimated` part of the PR is included (the
+`apps/fabric-example` hunk is not part of the published package), and the
+include hunk in `LayoutAnimationsProxy_Legacy.cpp` was adjusted to the 4.3.2
+release sources.
