+# Phase 1 Plan 7: Password Reset Navigation and Deep Linking Summary
+
+**Complete password reset navigation system with URL parameter extraction and deep linking support across mobile and web platforms**
+
+## Performance
+
+- **Duration:** 10 minutes
+- **Started:** 2026-01-28T17:10:56Z
+- **Completed:** 2026-01-28T17:20:43Z
+- **Tasks:** 2
+- **Files modified:** 7
+
+## Accomplishments
+- Integrated password reset routes into the main router with deep linking support
+- Added URL parameter extraction for reset tokens and email addresses
+- Updated login and signup pages with functional "Forgot Password?" links
+- Enhanced password reset confirmation page to handle deep linking parameters
+- Updated password update page to extract and use reset tokens from URLs
+- Added proper navigation guards to allow password reset routes regardless of authentication state
+- Created comprehensive integration tests for password reset flow verification
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Integrate password reset with navigation** - `680ecdc` (feat)
+2. **Task 2: Update pages with password reset links** - `53329c9` (feat)
+
+**Plan metadata:** Not yet committed (docs: complete plan)
+
+## Files Created/Modified
+- `lib/core/router/app_router.dart` - Added password reset routes, deep linking support, URL parameter extraction helpers
+- `lib/features/authentication/presentation/pages/login_page.dart` - Updated forgot password handler to navigate to reset page
+- `lib/features/authentication/presentation/pages/signup_page.dart` - Added forgot password link and handler
+- `lib/features/authentication/presentation/pages/reset_password_confirm_page.dart` - Enhanced to extract URL parameters for deep linking
+- `lib/features/authentication/presentation/pages/update_password_page.dart` - Added token extraction from URL parameters
+- `lib/main.dart` - Updated MaterialApp.router configuration for deep linking support
+- `test/integration_test/auth_flow_test.dart` - Created comprehensive integration tests for password reset flow
+
+## Decisions Made
+- Used GoRouter's built-in query parameter extraction rather than manual URL parsing
+- Made password reset routes publicly accessible to support email-based deep linking
+- Added helper methods in AppRouter for consistent URL parameter handling
+- Documented URL schemes for both mobile (sage://) and web (https://) deep linking
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None - all tasks completed successfully without issues.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Password reset navigation is fully functional with deep linking support
+- All authentication pages are properly connected with password reset links
+- Router configuration supports both mobile and web deep linking scenarios
+- Integration tests verify the complete password reset flow works correctly
+- Ready for Phase 2: Household Creation with complete authentication foundation
