+### [react-native+0.83.1+034+fix-fabric-collapsed-accessibility-announcement.patch](react-native+0.83.1+034+fix-fabric-collapsed-accessibility-announcement.patch)
+
+- Reason: Fixes a Fabric regression where VoiceOver on iOS only announces "expanded" but never "collapsed" for elements with `accessibilityState.expanded`. In `RCTViewComponentView.mm`, the code uses `value_or(false)` which skips the announcement entirely when `expanded` is `false`. This patch changes the logic to use `has_value()` and correctly announce both "expanded" and "collapsed" states, matching the old architecture (Paper) behavior.
