Debug-signed Android APK built locally with expo prebuild + gradlew assembleRelease (79MB, minSdk 24).
Ships without API keys: Google Maps tiles and the AI advisor are offline and the app says so on screen. Route scoring, the heatmap, community reports, emergency contacts and SOS all work with no key.
See docs/safeher-demo.mp4 for an 83s walkthrough recorded from this build.
