Verification limit
Code snippets are concise examples for operational guidance. A full SDK 56 sample app should be
maintained separately if compile-tested examples become required.
When a new Expo SDK patch or minor release ships, review sdk56-breaking-changes, expo-ui-native, and eas-update-ota.
When EAS Observe becomes GA, update beta wording in performance-profiling.
When the expo-widgets API reference alpha banner is removed, simplify the caveat.
When the Expo Router migration guide changes, re-check codemod commands and import boundaries.
When EAS CLI major versions change, update eas-build-pipeline and the Expo handbook check script together.
