Created backend/src/config/constants.js to centralize all magic numbers and configuration values used throughout the backend codebase. Changes: - Created constants.js with organized sections for: - SECURITY: JWT, rate limiting, password reset - AUTH: OTP configuration and rate limiting - SERVER: Port, body limits, startup delays - MQTT: Connection settings, cache limits - NOTIFICATIONS: Push settings, quiet hours, batching - SERIAL: Validation patterns and constraints - EMAIL: Template settings and defaults - CRON: Schedule configurations - STORAGE: Avatar storage settings - Updated files to use constants: - index.js: JWT validation, rate limits, startup delays - routes/auth.js: OTP generation, rate limits, JWT expiry - services/mqtt.js: Connection timeouts, cache size - services/notifications.js: Batch size, TTL, quiet hours - utils/serialValidation.js: Serial number constraints - Added comprehensive test suite (30 tests) for constants module - All tests passing (93 total including existing tests) - Validates reasonable values and consistency between related constants Benefits: - Single source of truth for configuration values - Easier to maintain and update settings - Better documentation of what each value represents - Improved code readability by removing hardcoded numbers - Testable configuration values 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Authentication Flow
The app uses email-based OTP authentication with two distinct paths:
Existing User (Login)
login.tsx -> Enter email -> welcome-back.tsx -> verify-otp.tsx -> Main App
- User enters email on login screen
- System checks if email exists in database
- If exists: navigates to "Welcome Back" screen, sends OTP
- User enters OTP code
- After verification: navigates to main app (tabs)
New User (Registration)
login.tsx -> Enter email -> verify-email.tsx (auto-sends OTP) -> verify-otp.tsx -> enter-name.tsx -> add-loved-one.tsx -> Main App
- User enters email on login screen
- System checks if email exists in database
- If NOT exists: navigates to "Verify Email" screen
- OTP is automatically sent when screen loads
- User can optionally enter a partner/referral code (6-digit numeric)
- User proceeds to OTP verification
- After verification: enters their name
- Then adds their first beneficiary (or skips)
- Finally navigates to main app
Partner/Referral Code
Partner codes are 6-digit numeric codes for marketing/referrals:
- Only available during NEW user registration (verify-email screen)
- NOT shown for existing users logging in
- Visual: 6 separate cells with hidden TextInput for keyboard
- Only accepts digits (non-numeric characters are filtered out)
- Test code "123456" available for development

Development Notes
Expo Go Limitations
Some features are stubbed when running in Expo Go:
expo-speech-recognition- Uses Alert fallback instead of native speechsherpa-onnx-tts- Uses expo-speech instead of native TTS
Running on Simulators
Use specific UDID for each port:
IOS_SIMULATOR_UDID=FCED72EF-3ADE-47D5-AC67-5C9B0DE59D7E npx expo start --port 8082 --ios
See ~/Desktop/dev instructions/SIMULATORS.md for full port-to-UDID mapping.
