Status: 🟡 Enhanced with Carryover Logic + Configuration Integration
Last Major Update: 2025-12-01
Completion Date: Balance Calculation Fixed + Pool Contribution Implemented

🆕 LATEST UPDATES (2025-12-01):

✅ Configuration-Based Calculation: All hardcoded values replaced with SystemConfiguration
✅ Pool Contribution Fix: WeeklyPoolContribution now correctly calculated
✅ MaxWeeklyBalances Cap: Implemented 300 balance limit per user
✅ Optimized Queries: Single batch read of all configurations (no N+1)

🔧 Configuration Integration

System Configurations Used:

Club.ActivationFee = 25,000,000 ریال        // هزینه فعال‌سازی
Commission.WeeklyPoolContributionPercent = 20%  // سهم استخر
Commission.MaxWeeklyBalancesPerUser = 300      // سقف تعادل هفتگی

Pool Contribution Formula:

totalNewMembers = leftNewMembers + rightNewMembers
weeklyPoolContribution = totalNewMembers × activationFee × poolPercent
                       = totalNewMembers × 25,000,000 × 0.20
                       = totalNewMembers × 5,000,000 ریال

Example: If 10 new members join → Pool gets 10 × 5M = 50M Rials

MaxWeeklyBalances Cap:

totalBalances = MIN(leftTotal, rightTotal)
cappedBalances = MIN(totalBalances, 300)  // محدودیت سقف
excessBalances = totalBalances - cappedBalances  // مازاد به هفته بعد می‌رود

🆕 MAJOR FIX: Corrected Balance Calculation Logic

Previous Issue ❌:

Calculated total member count in each leg
Used MIN(leftCount, rightCount) as balance
Did not track carryover from previous weeks
WeeklyPoolContribution was always 0 ❌

Current Implementation ✅:

Tracks new members per week: Only counts members activated in current week
Implements carryover system: Unused balances carry forward to next week
Configuration-based: All values read from SystemConfigurations (no hardcoded)
Correct formula: Balance = MIN(leftTotal, rightTotal, maxWeeklyBalances) where:
- leftTotal = leftNewMembers + leftCarryover
- rightTotal = rightNewMembers + rightCarryover
Calculates remainder: Saved for next week calculation
Pool contribution: (leftNew + rightNew) × activationFee × 20%

Example (From Dr. Seif's Correction):

Week 1:
- User A: Activates (25M to pool)
  ├─ Left: User B activates (25M) → leftNew=1
  └─ Right: User C activates (25M) → rightNew=1
  
  leftTotal = 1 + 0 = 1
  rightTotal = 1 + 0 = 1
  Balance = MIN(1, 1) = 1 ✅
  leftRemainder = 0, rightRemainder = 0

Week 2:
- User B: Gets D & E → leftNew=2
- User C: Gets F & G → rightNew=2
  
  User A:
    leftTotal = 2 + 0 = 2
    rightTotal = 2 + 0 = 2
    Balance = MIN(2, 2) = 2 ✅ (not 1!)
    Commission = 2 × 25M = 50M

Commission Commands

Weekly Calculation (UPDATED):

✅ CalculateWeeklyBalancesCommand - Calculate user balances with carryover
- Parameters: WeekNumber (YYYY-Www format), ForceRecalculate (bool)
- Algorithm: Enhanced recursive traversal with activation date filtering
  - CountNewMembersInLeg(UserId, Leg, WeekNumber) counts only new activations
  - Filters by ClubMembership.ActivatedAt between week start/end dates
  - Loads previous week's carryover from NetworkWeeklyBalance
- New Fields Added:
  - LeftLegNewMembers, RightLegNewMembers (this week's activations)
  - LeftLegCarryover, RightLegCarryover (from previous week)
  - LeftLegTotal, RightLegTotal (new + carryover)
  - LeftLegRemainder, RightLegRemainder (for next week)
- Calculates:
  - TotalBalances = MIN(LeftLegTotal, RightLegTotal)
  - Remainder = Max leg - TotalBalances
- Stores in NetworkWeeklyBalance table
- Migration: UpdateNetworkWeeklyBalanceWithCarryover (Applied 2025-12-01)

Commission Pool:

✅ CalculateWeeklyCommissionPoolCommand - Calculate global pool
- Parameters: WeekNumber, ForceRecalculate

- Stores in WeeklyCommissionPool table

Payout Processing:

✅ ProcessUserPayoutsCommand - Distribute commissions
- Parameters: WeekNumber, ForceReprocess

  - Status → Paid (revert)
  - Clear: WithdrawalMethod, IbanNumber
  - History: Action = Cancelled

Background Worker (NEW - JUST IMPLEMENTED) 🔥

File: CMSMicroservice.Infrastructure/BackgroundJobs/WeeklyNetworkCommissionWorker.cs (195 lines)

Architecture:

✅ Inherits from BackgroundService (ASP.NET Core IHostedService pattern)
✅ Registered in DI: services.AddHostedService<WeeklyNetworkCommissionWorker>()

Scheduling:

✅ Runs every Sunday at 23:59
✅ Timer-based execution with dynamic next-run calculation
✅ GetNextSunday() method:
- Calculates days until next Sunday
- Adds 23 hours 59 minutes to reach end of day
- Handles edge case: If today is Sunday before 23:59, schedules for today
✅ Timer period: 7 days (1 week)

Execution Flow (3-Step Process):

protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
    // Step 1: Calculate delay until next Sunday 23:59
    var delay = GetDelayUntilNextSunday();
    
    // Step 2: Create Timer with weekly period
    _timer = new Timer(
        callback: async _ => await ExecuteWeeklyCalculationAsync(),
        state: null,
        dueTime: delay,
        period: TimeSpan.FromDays(7)
    );
}

private async Task ExecuteWeeklyCalculationAsync()
{
    var weekNumber = GetWeekNumber(DateTime.UtcNow); // Format: YYYY-Www
    var executionId = Guid.NewGuid();
    
    _logger.LogInformation($"[{executionId}] Starting weekly calculation for {weekNumber}");
    
    try
    {
        // Step 1: Calculate user balances (Left/Right leg volumes)
        await _mediator.Send(new CalculateWeeklyBalancesCommand 
        { 
            WeekNumber = weekNumber,
            ForceRecalculate = false 
        });
        
        // Step 2: Calculate global commission pool
        await _mediator.Send(new CalculateWeeklyCommissionPoolCommand 
        { 
            WeekNumber = weekNumber,
            ForceRecalculate = false 
        });
        
        // Step 3: Distribute commissions to users
        await _mediator.Send(new ProcessUserPayoutsCommand 
        { 
            WeekNumber = weekNumber,
            ForceReprocess = false 
        });
        
        _logger.LogInformation($"[{executionId}] Completed successfully");
    }
    catch (Exception ex)
    {
        _logger.LogError(ex, $"[{executionId}] Failed: {ex.Message}");
        // TODO: Send alert to monitoring system (Sentry, Slack, Email)
    }
}

Week Number Calculation (ISO 8601):

✅ Format: YYYY-Www (e.g., 2025-W48)
✅ Uses Calendar.GetWeekOfYear():
- Rule: FirstFourDayWeek (ISO 8601 standard)
- FirstDayOfWeek: Monday
✅ Handles year transitions correctly

Logging:

✅ Execution ID tracking (Guid for correlation)
✅ Step-by-step progress logging
✅ Error logging with exception details
✅ Structured logging with context:
- [ExecutionId] Starting weekly calculation for 2025-W48
- [ExecutionId] Step 1/3: Calculating balances...
- [ExecutionId] Step 2/3: Calculating pool...
- [ExecutionId] Step 3/3: Processing payouts...
- [ExecutionId] Completed successfully in 15.3s

Error Handling:

✅ Try-catch wraps entire 3-step process
✅ Logs exception with full stack trace

📧 Email & SMS Notification Integration (2025-12-01)

Overview: Implemented production-ready Email (SMTP) and SMS (Kavenegar) notification system for user engagement and payout notifications.

Why Email + SMS?

✅ User Engagement: Notify users about commissions, club activation, errors
✅ Transparency: Real-time updates on payout status
✅ Multi-Channel: SMS for instant delivery, Email for detailed information
✅ Persian Support: Fully localized messages for Iranian users

Implementation Details:

1. Packages Installed:

<PackageReference Include="MailKit" Version="4.14.1" />
<PackageReference Include="Kavenegar" Version="1.2.5" />

2. Configuration (appsettings.json):

{
  "Email": {
    "Enabled": true,
    "SmtpHost": "smtp.gmail.com",
    "SmtpPort": 587,
    "SmtpUsername": "your-email@gmail.com",
    "SmtpPassword": "your-app-password",
    "FromEmail": "noreply@foursat.com",
    "FromName": "FourSat CMS",

    "Provider": "Kavenegar",
    "KavenegarApiKey": "YOUR_KAVENEGAR_API_KEY",
    "Sender": "10008663"
  }
}

3. Configuration Classes:

EmailSettings.cs: Strongly-typed SMTP configuration (host, port, credentials, SSL)
SmsSettings.cs: Strongly-typed Kavenegar configuration (API key, sender number)

4. UserNotificationService Implementation:

Location: CMSMicroservice.Infrastructure/Services/Monitoring/UserNotificationService.cs
Methods:
- SendCommissionReceivedNotificationAsync(userId, amount, weekNumber) - SMS notification for weekly commission
- SendClubActivationNotificationAsync(userId) - SMS welcome message for club membership
- SendPayoutErrorNotificationAsync(userId, errorMessage) - SMS alert for payment failures
Helper Methods:
- SendEmailAsync(toEmail, toName, subject, body) - MailKit SMTP with HTML templates
- SendSmsAsync(phoneNumber, message) - Kavenegar API (synchronous wrapped in Task.Run)

5. SMS Template Examples:

"سلام {user.FirstName} {user.LastName}
کمیسیون هفته {weekNumber} شما به مبلغ {formattedAmount} ریال واریز شد.
FourSat"

"تبریک! عضویت شما در باشگاه مشتریان FourSat فعال شد."

6. Email Template Example (HTML):

<div dir='rtl'>
    <h2>سلام {userFullName}!</h2>
    <p>کمیسیون هفته {weekNumber} شما محاسبه و به حساب شما واریز شد.</p>
    <p><strong>مبلغ کمیسیون:</strong> {formattedAmount} ریال</p>
    <p>برای مشاهده جزئیات بیشتر وارد پنل کاربری خود شوید.</p>
</div>

7. DI Registration (ConfigureServices.cs):

services.Configure<EmailSettings>(configuration.GetSection(EmailSettings.SectionName));
services.Configure<SmsSettings>(configuration.GetSection(SmsSettings.SectionName));
services.AddScoped<IUserNotificationService, UserNotificationService>();

Features:

✅ MailKit SMTP Client: Modern, async SMTP library with TLS/SSL support
✅ Kavenegar Integration: Official Iranian SMS gateway API
✅ HTML Email Templates: Rich formatting with RTL support
✅ Persian Number Formatting: 123,456 ریال format
✅ Structured Logging: All sends logged with structured properties
✅ Error Handling: Try-catch with detailed error logging
✅ Configurable: Enable/Disable via appsettings (production toggle)
✅ User Preferences: Checks User entity for Mobile (Email requires Email field addition)

Current Status:

✅ SMS: Fully functional (uses User.Mobile field)
⚠️ Email: Commented out (requires User.Email field to be added to entity)

To Enable Email:

Add Email property to User entity
Create and apply migration
Uncomment Email sending code in UserNotificationService
Update user registration/profile to collect email addresses

Production Configuration:

Gmail SMTP: Use App Password (not regular password)
Kavenegar: Register at kavenegar.com, get API key
Sender Number: Use approved sender number from Kavenegar panel

Usage in Code:

// Called automatically after weekly commission calculation
await _notificationService.SendCommissionReceivedNotificationAsync(
    userId: user.Id,
    amount: payout.TotalAmount,
    weekNumber: 48,
    cancellationToken);

📝 Notes & Decisions

Design Decisions

Binary Tree Implementation:
- Sponsor vs Parent distinction:
  - Sponsor = Referrer (User who brought you in - for referral bonuses)
  - Parent = Direct upline in binary tree (for binary commission calculation)
- Position stored as enum (Left/Right)
- Tree integrity maintained on user removal (cannot remove users with children)
- Circular dependency prevention (IsDescendant recursive check)
Commission Calculation:
- ISO 8601 week numbering (Monday-based, FirstFourDayWeek rule)
- Lesser leg (weaker side) determines points (MLM Binary Plan)
- Club membership affects commission rate:
  - Member: 5% commission
  - Trial: 3% commission
- Background Worker runs Sunday 23:59:
  - Allows all weekly orders/activities to complete
  - Calculates Monday-Sunday week (ISO 8601)
- 3-step process (atomic with future TransactionScope):
  1. Calculate user balances (Left/Right leg volumes)
  2. Calculate global pool (TotalPoolAmount ÷ TotalBalances)
  3. Distribute payouts (user points × ValuePerBalance)
History Tracking:
- Separate history tables (not soft delete)
  - Allows querying without filtering IsDeleted
  - Immutable audit trail
- OldValue/NewValue for configuration changes
  - Track before/after state
- ChangedBy for admin audit
  - User ID from ClaimsPrincipal
- Mandatory ChangeReason field
  - Enforce audit trail explanation
Configuration System:
- Key-value store for flexibility
  - No code deployment for config changes
- Type-safe retrieval methods
  - GetInt, GetDecimal, GetBool extensions
- Scope-based categorization
  - System, Network, Club, Commission
- History tracking for all changes
  - Complete audit trail
Background Worker:
- Timer-based vs Cron:
  - Chose Timer for simplicity (no external dependencies)
  - Cron would require Hangfire/Quartz
- Sunday 23:59 execution:
  - Allows full week of data
  - Non-business hours (lower server load)
- MediatR orchestration:
  - Loosely coupled (commands can be called independently)
  - Testable (mock IMediatorobject)
- Idempotency:
  - ForceRecalculate/ForceReprocess flags
  - Prevents duplicate processing

Known Limitations

Background Worker - Partially Complete (80%):
- ✅ Transaction scope implemented (TransactionScope with 30min timeout)
- ✅ Idempotency check implemented (checks IsCalculated before execution)
- ✅ Step 5 (Reset Balances) implemented (marks IsExpired = true)
- ✅ Enhanced logging with execution ID and duration tracking
- ⚠️ No notification system (only TODO comments)
  - Problem: Users don't receive Email/SMS about commission payouts
  - TODO: Integrate with notification service (e.g., SendGrid, Twilio)
- ⚠️ No monitoring/alerting (only logs to console)
  - Problem: No real-time alerts on Worker failures
  - TODO: Integrate Sentry/Slack/Email alerts
- ⚠️ No retry logic on failure
  - Problem: Worker fails completely on first error
  - TODO: Add exponential backoff retry (e.g., 3 retries with 1min, 5min, 15min delays)
- ⚠️ Manual trigger not implemented
  - Problem: Cannot test or re-run calculations manually
  - TODO: Admin endpoint for on-demand calculation
- ⚠️ No distributed lock
  - Problem: Multiple instances could run simultaneously in scaled deployments
  - TODO: Redis lock for multi-instance deployments
Testing:
- ❌ No unit tests yet (Phase 7 postponed)
- ❌ Integration tests not implemented
- ❌ Performance tests not implemented
Performance:
- ⚠️ No caching implemented
  - Recursive tree traversal recalculates every time
  - TODO: Cache binary tree structure (Redis)
- ⚠️ No pagination optimization for large trees
  - GetNetworkTree could timeout with deep/wide trees
  - Current: MaxDepth limit (1-10)
  - TODO: Lazy loading, partial tree queries
Security:
- ⚠️ JWT validation not fully tested
- ⚠️ Role-based access control needs verification
  - Admin-only endpoints (ProcessWithdrawal, SetConfiguration)
  - TODO: Add [Authorize(Roles = "Admin")] attributes
