Mobile App Integration Progress - Session Summary

Date: December 12, 2025
Session Focus: Wiring mobile app to backend systems

✅ Completed Today

1. Member Profile API (High Priority #2)

Backend:

• Created /v1/members/{coop_id}/{did} endpoint in gateway
• Returns comprehensive profile data:
  • Role (Steward/Facilitator/Participant)
  • Balance in hours
  • Transaction count
  • Joined timestamp
  • Placeholders for name and trust_score (future)
• 3 passing integration tests
• 137 total gateway tests passing

SDK:

• Added MemberProfile type to TypeScript SDK
• Added getMemberProfile(coopId, did) method
• TypeScript SDK builds cleanly
• Ready to use in React Native

Status: ✅ Complete - API operational, ready to wire to mobile UI

2. Real-time WebSocket Updates (High Priority #3)

HomeScreen:

• Connects to WebSocket on mount
• Listens for PaymentCreated events
• Auto-refreshes balance and transactions when user involved in payment
• Disconnects cleanly on unmount
• No polling needed!

GovernanceScreen:

• Listens for GovernanceVoteCast events
• Listens for GovernanceProposalCreated events
• Auto-refreshes proposal list when governance activity occurs
• Immediate feedback for collaborative actions

Benefits:

• Users see updates in real-time
• Better UX for cooperative scenarios (multiple people transacting)
• Reduces unnecessary API calls
• Foundation for future notifications

Status: ✅ Complete - WebSocket events wired to UI refresh logic

3. Bug Fixes & Test Improvements

React Native SDK:

• Fixed test storage key names for SecureStore compatibility
• All 86 tests passing (excluding wallet.test.ts ESM issue)

Gateway:

• SDIS endpoints fully integrated
• 134 tests passing (including 19 SDIS integration tests)

📊 Current Test Status

🎯 What's Working End-to-End

Financial Features (Pilot-Ready)

1. Login → Cooperative ID → DID signature → JWT token
2. Send Payment → Recipient DID + amount → Mutual credit transaction
3. View Balance → Real balance from ledger
4. Transaction History → Real transactions with pagination
5. Real-time Payment Updates → WebSocket events → Auto-refresh

Governance Features (Pilot-Ready)

1. View Proposals → Real proposals from domain
2. Cast Vote → For/Against on active proposals
3. Vote Tally → Real-time vote counts
4. Real-time Governance Updates → WebSocket events → Auto-refresh

Identity Features (API Ready)

1. SDIS Verification → Level 1 & 2 verification endpoints
2. Member Profiles → Role, balance, transaction count
3. DID Resolution → Identity lookup

🚧 Remaining High-Priority Items

From Original List

📝 Next Steps

Immediate (Can Do Now)

1. Wire Member Profile to Identity Screen

   • Replace "Demo User" with real getMemberProfile() call
   • Show actual transaction count, balance, role
   • Display "Member Since" timestamp

2. Add Toast/Snackbar for WebSocket Events

   • Show "Payment received from Alice" notification
   • Show "New proposal: Budget Approval" notification
   • Use react-native-paper Snackbar or similar

3. Error Message Improvements

   • Better error handling in payment screen
   • Network error retry UI
   • Input validation messages

Near-term (Requires Libraries)

4. QR Scanner Integration

   • Add expo-camera or react-native-camera
   • Wire to payment recipient field
   • Wire to identity verification

5. Biometric Auth

   • Add expo-local-authentication
   • Unlock wallet with fingerprint/face
   • Optional but nice-to-have

Medium-term (Requires Backend Work)

6. Display Names

   • Add name field to identity system
   • Wire to member profile API
   • Show names instead of DIDs where possible

7. Trust Scores

   • Integrate trust graph with member profiles
   • Display trust scores in identity screen
   • Use for reputation display

8. Push Notifications

   • FCM for payment alerts
   • Background notifications
   • Deep linking from notifications
