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 - **Prerequisite**: CalculateWeeklyBalances must run first - Aggregation: * TotalPoolAmount = SUM(WeeklyPoolContribution) from all users * TotalBalances = SUM(LesserLegPoints) from all users * ValuePerBalance = TotalPoolAmount ÷ TotalBalances (Rial per point) - Applies club membership commission rates (member: 5%, trial: 3%) - Stores in `WeeklyCommissionPool` table **Payout Processing**: - ✅ `ProcessUserPayoutsCommand` - Distribute commissions - Parameters: WeekNumber, ForceReprocess - **Prerequisite**: CalculateWeeklyCommissionPool must run first - For each user with `LesserLegPoints > 0`: * TotalAmount = User's LesserLegPoints × ValuePerBalance * Creates `UserCommissionPayout` record (Status = Pending) * Records in `CommissionPayoutHistory` (Action = Created) - Idempotent: ForceReprocess allows recalculation **Withdrawal System**: - ✅ `RequestWithdrawalCommand` - User withdrawal request - Parameters: PayoutId, WithdrawalMethod (Cash/Diamond), IbanNumber (for Cash) - Validations: * Payout must be in Paid status * IBAN format: `^IR\d{24}$` (for Cash method) - Updates: Status → WithdrawRequested - History: Action = WithdrawRequested - ✅ `ProcessWithdrawalCommand` - Admin approval/rejection - Parameters: PayoutId, IsApproved, AdminNotes - **If Approved**: * Status → Withdrawn * **If Diamond**: Add TotalAmount to `UserWallet.DiscountBalance` (instant) * **If Cash**: External bank transfer (uses stored IBAN) * History: Action = Withdrawn - **If Rejected**: * 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()` **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): ```csharp 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);

**gRPC**: Grpc.AspNetCore - **CQRS**: MediatR 12.x - **Validation**: FluentValidation 11.x - **Mapping**: AutoMapper 12.x - **Background Jobs**: IHostedService (ASP.NET Core built-in) - **Logging**: ILogger (Microsoft.Extensions.Logging) - **Serialization**: System.Text.Json --- ## 📝 Notes & Decisions ### Design Decisions 1. **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) 2. **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) 3. **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 4. **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 5. **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 1. **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 2. **Testing**: - ❌ No unit tests yet (Phase 7 postponed) - ❌ Integration tests not implemented - ❌ Performance tests not implemented 3. **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 4. **Security**: - ⚠️ JWT validation not fully tested - ⚠️ Role-based access control needs verification * Admin-only endpoints (ProcessWithdrawal, SetConfiguration) * TODO: Add [Authorize(Roles = "Admin")] attributes --- ## 🔗 Related Documentation - **System Design**: [network-club-commission-system-v1.1.md](./network-club-commission-system-v1.1.md) - Complete system specifications (Business rules, formulas, workflows) - **Database Model**: [model.ndm2](./model.ndm2) - ER diagram (Navicat Data Modeler format) - **CMS Business Logic**: [cms-data-and-business.md](./cms-data-and-business.md) - Original business rules (Persian) - **BackOffice README**: [../../BackOffice/README.md](../../BackOffice/README.md) - Admin dashboard documentation - **BackOffice.BFF README**: [../../BackOffice.BFF/README.md](../../BackOffice.BFF/README.md) - BFF gateway documentation --- ## 📞 Contact & Support **Developer**: Masoud (GitHub Copilot assisted) **Last Updated**: 2024-11-29 **Repository**: FourSat (local workspace) **Phase**: 7/10 Completed (Background Worker JUST COMPLETED - Phase 4) --- **Legend**: - ✅ = Completed - 🚧 = In Progress - ⏸️ = Postponed - ❌ = Not Started - 🟡 = Partially Complete - 🆕 = Newly completed today - ⚠️ = Warning/Limitation/TODO
