TRY ARP CLOUD
VERSION v0.1 — DRAFT

Mobile

The ARP mobile owner app runs on iOS and Android via Expo. It lives in the separate private repo github.com/KybernesisAI/arp-mobile and mirrors the desktop owner app's features — pairing, consent screens, audit viewer, revocation — with two platform-native additions:

  1. Principal key in hardware. The browser-held did:key from the desktop flow moves to iOS Secure Enclave / Android Keystore on first mobile login. Recovery is still via the 12-word phrase (Phase 8.5).
  2. Biometric gates per risk tier. Scopes tagged critical in the catalog require Face ID / Touch ID / Android Biometric before the signed request leaves the device.

Phase status

Phase 8 shipped the scaffold: Expo SDK 52, RN 0.76.3, all routes from the phase brief, 18/18 jest tests, expo prebuild clean on both platforms. App Store and Play Store submissions are Phase 10 — public launch is explicitly after Phase 9 (this site, cloud-side endpoints, WebAuthn).

Architecture

Same seven-layer stack as the sidecar; only the client surface + the principal-key storage differ. DIDComm isolation + obligation-merge invariants hold — mobile imports @kybernesis/arp-sdk the same way desktop adapters do, and the transport boundary is @kybernesis/arp-transport.
