Logic Flow Structure

Root: User Authentication Flow

IF user.isRegistered = true

→ Check login credentials

IF credentials.valid = true

→ Grant system access

IF credentials.valid = false

→ Show error message

→ Retry authentication (max 3 attempts)

IF user.isRegistered = false

→ Redirect to registration flow

Validation Results

No infinite loops detected
All conditions have defined outcomes
No orphaned branches identified
Warning: Consider adding timeout handling for authentication attempts

Structured Summary

Initial Condition Check: Verify if the user is registered in the system.
Path 1 - Registered User: Prompt for login credentials and validate them against stored data.
Path 2 - New User: Redirect to registration flow to collect user information.
Authentication Logic: Compare provided credentials with database records.
Success Path: Grant system access, generate session token, log activity.
Failure Path: Show appropriate error message, increment failure counter, limit attempts.
Security Measures: Implement account lockout after 3 failed attempts, provide password reset option.

Implementation Guidelines

Form Implementation

Create a multi-step form with clear error states and validation feedback. Use client-side validation for immediate user feedback and server-side validation for security.

Application Logic

Implement using stateful components that track user progress. Consider using a state machine pattern to manage complex transitions between states.

Automation Systems

Use event-driven architecture to trigger appropriate actions based on user inputs. Implement timeouts and retry mechanisms for external service calls.

Technical Recommendations

Store authentication state in secure HTTP-only cookies
Implement CSRF protection for all form submissions
Use proper input sanitization to prevent injection attacks
Log authentication attempts for security auditing

Edge Case Handling

Network Interruptions

Implement offline detection and automatic retry logic when connection is restored.

Session Expiration

Gracefully handle timeout scenarios with session refresh options and data preservation.

Database Unavailability

Implement circuit breaker pattern with friendly degradation messaging.

External API Failures

Use fallback mechanisms and local caching where applicable.

Recommended Fallback Scenarios

Implement progressive enhancement to support users with JavaScript disabled
Add timeout handling for third-party authentication providers
Create special handling for users with browser cookies disabled
