Opinionated Expo React Native scaffold: RevenueCat paywall, AdMob, i18n, NativeTabs

Test report

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 17, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 8859812

A single-file opinionated Expo guide that bans real footguns (AsyncStorage, lineHeight, expo-av, plain Tabs) and mandates the AdMob app.json plugin that otherwise crashes with GADInvalidInitializationException. Could not compile the delta: realizing its value needs a full Expo/EAS toolchain plus RevenueCat and AdMob accounts, so the edge over baseline is plausible but unproven by execution here.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
