Implementation Complete Summary

Date: 2025-10-31
Status: ✅ ALL HIGH-PRIORITY ITEMS COMPLETE

---

✅ Completed Implementation

1. ES256K JWT Token Generation (Item #1) - COMPLETE

Implementation:

• Added did-jwt@^7.0.0 and ethers@^6.0.0 dependencies
• Implemented generateEndorserJWT() function in test-user-zero.ts
• Derives Ethereum private key from seed phrase using ethers.HDNodeWallet
• Uses did-jwt.SimpleSigner for ES256K signing
• Creates proper ES256K signed JWTs matching TimeSafari's pattern

Files Modified:

• test-apps/daily-notification-test/src/config/test-user-zero.ts - Added generateEndorserJWT() function
• test-apps/daily-notification-test/src/views/HomeView.vue - Updated to use generateEndorserJWT()
• test-apps/daily-notification-test/package.json - Added dependencies

Architecture:

• JWT generation happens in TypeScript (no Java DID libraries needed)
• Native fetcher receives pre-generated tokens
• Matches TimeSafari's production pattern

---

2. Network Security Configuration (Item #15) - COMPLETE

Implementation:

• Created network_security_config.xml allowing cleartext HTTP traffic to 10.0.2.2, localhost, and 127.0.0.1
• Updated AndroidManifest.xml to reference the network security config

Files Created/Modified:

• test-apps/daily-notification-test/android/app/src/main/res/xml/network_security_config.xml (created)
• test-apps/daily-notification-test/android/app/src/main/AndroidManifest.xml (line 10)

Purpose:

• Enables HTTP connections to http://10.0.2.2:3000 from Android emulator
• Required for localhost testing (emulator's special IP for host machine)

---

3. TypeScript/Java Interface Updates - COMPLETE

Changes:

• Updated configureNativeFetcher() to accept jwtToken instead of jwtSecret
• Updated all TypeScript definitions, Java plugin, and native interface
• Removed as any type assertion from HomeView.vue
• Rebuilt plugin to update dist/definitions.d.ts

Files Modified:

• src/definitions.ts - Updated method signature and JSDoc
• android/plugin/.../DailyNotificationPlugin.java - Updated parameter handling
• android/plugin/.../NativeNotificationContentFetcher.java - Updated interface
• test-apps/.../TestNativeFetcher.java - Simplified (removed JWT generation)
• test-apps/.../HomeView.vue - Updated to use new token-based approach
• dist/definitions.d.ts - Rebuilt with updated types

---

4. TestNativeFetcher Simplification - COMPLETE

Changes:

• Removed entire generateJWTToken() method (HMAC-SHA256 implementation)
• Removed unused imports (Mac, SecretKeySpec, Base64, MessageDigest)
• Changed jwtSecret field → jwtToken
• Updated to use pre-generated token directly in Authorization header

Files Modified:

• test-apps/daily-notification-test/android/app/src/main/java/com/timesafari/dailynotification/test/TestNativeFetcher.java

🚀 Ready for Testing

Prerequisites Complete:

• ✅ ES256K JWT generation implemented
• ✅ Network security config in place
• ✅ All interfaces updated
• ✅ Plugin rebuilt with correct types

Next Steps for Testing:

1. Enable Real API Calls:

   // In test-apps/daily-notification-test/src/config/test-user-zero.ts
   // Change line 28:
   serverMode: "localhost" as "localhost" | "staging" | "production" | "mock" | "custom",
   

2. Build and Run Android Test App:

   cd test-apps/daily-notification-test
   npm run build
   npx cap sync android
   npx cap run android
   

3. Verify JWT Generation:

   • Check console logs for JWT generation
   • Verify token is passed to native fetcher
   • Check logcat for native fetcher configuration

4. Test API Calls:

   • Schedule a notification
   • Verify prefetch occurs
   • Check that API calls succeed with ES256K tokens
   • Verify notifications appear

📋 Remaining Optional Tasks

Medium Priority:

• Item #4: Add root.has("data") validation in API response parser
• Item #5: Enhance logging with timing and structured tags

Low Priority:

• Items #7-11: Unit tests, JWT utility extraction, interceptors, caching, metrics

Documentation:

• Update docs/NATIVE_FETCHER_CONFIGURATION.md to reflect token-based approach
• Document ES256K JWT generation pattern for TimeSafari integration
