+# Builds the Expo example (Example/expoUsePushy, `use_expo_modules!`) against
+# the local package on both platforms. Nothing else compiles the Expo side:
+# the podspec's Expo detection (Podfile scan, expo/expo-modules-core lookup,
+# the ExpoModulesCore version gate that selects EXPO_SUPPORTS_BUNDLEURL), the
+# Swift ReactDelegateHandler and the Kotlin module. SDK 57 removed the
+# createBridge fallback and broke exactly this path once; the e2e app is a
+# bare React Native project and never reaches it.
+#
+# Build only (no simulator/emulator run): the update flow itself is covered
+# by e2e-ios / e2e-android. Paths are limited to the Expo integration's
+# inputs; changes to the native .mm/.java sources are already compiled by
+# the e2e workflows.
