Build Auth Screens

Step 3: ConsentScreen.tsx

Three sequential consent steps (all required before proceeding):

1. Not Therapy — "Relio is NOT therapy, counseling, or a substitute for professional mental health care." [Checkbox]
2. Privacy Model — 3-Tier explanation with interactive before/after demo. "Your raw words are NEVER shown to your partner." [Checkbox]
3. AI Processing — GDPR Art. 22 consent. "Relio uses AI to detect patterns and rephrase your words." [Checkbox]

• Each checkbox calls POST /api/v1/consent with type + version
• Link to full ToS and Privacy Policy at bottom of each screen
• All three must be checked to proceed

Step 4: OnboardingScreen.tsx — Stage Selection

• Four card-based options (NOT radio buttons): Dating, Married, Pre-Divorced, Divorced
• Each card: 1 emoji + 1 user-friendly label + 1 sentence description
• NO clinical language: "We're going through a rough patch" not "Pre-Divorced phase"
• "I'd rather not say" option → defaults to dating agent
• Selection changeable anytime from Settings
• No option pre-selected (avoid anchoring bias)

Step 5: InvitePartnerScreen.tsx

• Display 6-char invite code in large format with hyphen: RLO-K7M
• Copy-to-clipboard button
• QR code display (fetched from /api/v1/qr/:code)
• Share button using React Native's native share sheet (deep link)
• "Your partner hasn't joined yet" status with re-invite button
• Timer showing expiry countdown

Step 6: AcceptInviteScreen.tsx

• Auto-opened via deep link (myrelio.io/invite/{code})
• Shows Partner A's first name only
• Accept / Decline buttons
• On accept: celebration animation → navigate to SharedChatScreen
• On decline: silent — no notification to Partner A. Generic "link expired" if blocked.

Step 7: Biometric Gate

• Use expo-local-authentication for FaceID/TouchID/fingerprint
• Enforce on every app re-open (configurable: every time / after 5min / after 1hr)
• Fallback to app PIN if biometric unavailable
• Settings toggle to configure timing
• NEVER skip biometric in production builds

Constraints

• NEVER store sensitive data in AsyncStorage (use expo-secure-store)
• NEVER show Partner A's full profile to Partner B during invitation
• NEVER auto-select a relationship stage
• All screens must support dark mode and accessibility (VoiceOver/TalkBack)
• Emergency resource footer visible on every onboarding screen
