Proof

expo-navigation-bar

real upstream package — not intercepted. the app's expo-navigation-bar JS runs from the bundle against the ExpoNavigationBar native module (native-seams/expo-navigation-bar.ts, mirroring NavigationBarModule.kt at 58.0.0-canary): visibility and style over the live engine system-bars mirror with per-device navigation-bar dimensions, transient-swipe behavior on hide/show, didChange events with the decor visibility int, and the config-plugin hidden/style theme defaults. iOS keeps upstream's unsupported path (the package ships no iOS native code). 4.x/5.x used the removed background/border/button/position/behavior surface and are out of range.

API coverage

No visual proof cases have been published for this package yet. The registry summary below describes what the compat layer implements.

Working

NavigationBar component with the entries-stack merge, NavigationBar.setStyle/setHidden statics, setVisibilityAsync/getVisibilityAsync round-trip (visible default), addVisibilityListener didChange events on explicit, transient-reveal, auto-hide, and status-bar visibility changes with visibility plus rawVisibility, useVisibility hook, plugin hidden/style initial theme

Missing

config-plugin enforceContrast:false opt-out (Peach runs no prebuild, so contrast stays OS-enforced as on an unthemed device) and extra-window style/visibility fan-out (Peach has a single tenant window)
