Android wrapper app (android/): a minimal TWA around v3.coinos.io whose whole reason to exist is intent registration — lightning:/bitcoin:/nostr:/lnurl:/lnurlw:/lnurlp: VIEW intents and the same schemes via NFC NDEF dispatch (bolt cards, address stickers; NFC declared required=false), plus verified https links to the site. LauncherActivity forwards a scheme URI into the web app as ?u=<encoded>; the web app reads it BEFORE features construct — a nostr npub/nprofile rewrites itself onto the existing /npub profile deep link, payment URIs stash and dispatch through handleScanned (the QR path) once a wallet is open, and the param is stripped from the URL either way. assetlinks.json (static/.well-known/, copied by build.js) vouches for the signing cert so the TWA runs URL-bar-less; the built APK is served at /coinos.apk for sideloading. Signing keystore lives in android/ GITIGNORED (keystore.properties beside it) — the assetlinks fingerprint pins it, so losing it means re-shipping assetlinks too. Verified: headless ?u= routing (lightning → Send with invoice filled + URL cleaned; nostr → profile page), APK installed on a real phone via adb, schemes registered (chooser appears where other wallets also claim lightning:)
