+# react-native-reanimated@4.5.3.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 hunks
+were rebased onto the 4.5.3 release sources.
+
+Note that upstream's own `pullTransaction` rework in 4.5.3 (the new
+`reconcileContradictedRemovals`) covers a different case - a `Create`/`Insert`
+contradicting a *withheld* exit removal - and does not subsume the deleted-tag
+`Update` filter here, which guards against the `LayoutAnimationDriver` final
+keyframe. That driver only runs at all once this patch frees the delegate slot.
