-### ✅ Phase 4: Commission Calculation & Background Worker (100% Complete) 🆕
+### ✅ Phase 4: Commission Calculation & Background Worker (100% Complete) ✅

-**Status**: ✅ Fully Implemented  
-**Completion Date**: 2024-11-29 (Worker just completed today!)
+**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):**
+
+1. **✅ Configuration-Based Calculation**: All hardcoded values replaced with SystemConfiguration
+2. **✅ Pool Contribution Fix**: WeeklyPoolContribution now correctly calculated
+3. **✅ MaxWeeklyBalances Cap**: Implemented 300 balance limit per user
+4. **✅ Optimized Queries**: Single batch read of all configurations (no N+1)
+
+---
+
+#### **🔧 Configuration Integration**
+
+**System Configurations Used**:
+```csharp
+Club.ActivationFee = 25,000,000 ریال        // هزینه فعال‌سازی
+Commission.WeeklyPoolContributionPercent = 20%  // سهم استخر
+Commission.MaxWeeklyBalancesPerUser = 300      // سقف تعادل هفتگی
+```
+
+**Pool Contribution Formula**:
+```csharp
+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**:
+```csharp
+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**:
- ✅ `CalculateWeeklyBalancesCommand` - Calculate user balances
+**Weekly Calculation** (UPDATED):
+- ✅ `CalculateWeeklyBalancesCommand` - Calculate user balances with carryover
  - Parameters: WeekNumber (YYYY-Www format), ForceRecalculate (bool)
-  - **Algorithm**: Recursive binary tree traversal
-    - `CalculateLegBalances(UserId, Position)` counts all descendants
-    - Formula: Balance = 1 (child) + childLeftLeg + childRightLeg
+  - **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

+  - **New Fields Added**:
+    * `LeftLegNewMembers`, `RightLegNewMembers` (this week's activations)
+    * `LeftLegCarryover`, `RightLegCarryover` (from previous week)
+    * `LeftLegTotal`, `RightLegTotal` (new + carryover)
+    * `LeftLegRemainder`, `RightLegRemainder` (for next week)
  - Calculates:
-    * LeftVolume = Total users in left leg
-    * RightVolume = Total users in right leg
-    * WeakerLegVolume = MIN(Left, Right)
-    * LesserLegPoints = WeakerLegVolume (MLM Binary Plan)
-  - Stores in `NetworkWeeklyBalance` table (Upsert if ForceRecalculate)

+- ✅ **Job Persistence**: Jobs survive application restarts (SQL Server storage)
+- ✅ **Cron Scheduling**: Flexible scheduling (weekly, daily, custom intervals)
+- ✅ **Manual Triggers**: On-demand job execution via API
+- ✅ **Retry Support**: Automatic retry on failure with exponential backoff
+- ✅ **Distributed**: Can run on multiple servers with coordination
+
+**Implementation Details**:
+
+**1. Packages Installed:**
+```xml
+<PackageReference Include="Hangfire.AspNetCore" Version="1.8.22" />
+<PackageReference Include="Hangfire.SqlServer" Version="1.8.22" />
+<PackageReference Include="Microsoft.Extensions.Diagnostics.HealthChecks.EntityFrameworkCore" Version="9.0.0" />
+```
+
+**2. Hangfire Configuration (Program.cs):**

+// Services
+builder.Services.AddHangfire(config => config
+    .SetDataCompatibilityLevel(CompatibilityLevel.Version_180)
+    .UseSimpleAssemblyNameTypeSerializer()
+    .UseRecommendedSerializerSettings()
+    .UseSqlServerStorage(builder.Configuration["ConnectionStrings:DefaultConnection"]));
+builder.Services.AddHangfireServer();
+
+// Dashboard
+app.UseHangfireDashboard("/hangfire");
+
+// Recurring Job Registration
+recurringJobManager.AddOrUpdate<WeeklyCommissionJob>(
+    recurringJobId: "weekly-commission-calculation",
+    methodCall: job => job.ExecuteAsync(CancellationToken.None),
+    cronExpression: "5 0 * * 0", // Sunday at 00:05 UTC
+    options: new RecurringJobOptions { TimeZone = TimeZoneInfo.Utc });
+```
+
+**3. WeeklyCommissionJob Class:**
+- **Location**: `CMSMicroservice.Infrastructure/BackgroundJobs/WeeklyCommissionJob.cs`
+- **Purpose**: Refactored from `WeeklyNetworkCommissionWorker` (BackgroundService)
+- **Features**:
+  - Scoped DI (IMediator, ILogger, IApplicationDbContext injected per job execution)
+  - Polly retry pipeline (3 attempts, exponential backoff)
+  - WorkerExecutionLog creation and update
+  - Transaction scope for atomicity
+  - Idempotency check (skip if already calculated)
+- **Execution Flow**: Same 3-step process (CalculateBalances → CalculatePool → ProcessPayouts)
+
+**4. Admin API Endpoints:**
+- **Controller**: `CMSMicroservice.WebApi/Controllers/AdminController.cs`
+- **Endpoints**:
+  - `POST /api/admin/trigger-weekly-calculation` - Enqueue immediate job execution
+  - `POST /api/admin/trigger-recurring-job-now` - Trigger scheduled job immediately
+  - `GET /api/admin/recurring-jobs-status` - Get list of registered recurring jobs
+- **Response Example**:
+  ```json
+  {
+    "success": true,
+    "jobId": "8c7f4a2e-1234-5678-90ab-cdef12345678",
+    "message": "Weekly calculation job enqueued successfully",
+    "dashboardUrl": "/hangfire/jobs/details/8c7f4a2e-1234-5678-90ab-cdef12345678"
+  }
+  ```
+
+**5. Health Check Endpoints:**
+- `/health` - Overall health (database + application)
+- `/health/ready` - Readiness probe (for Kubernetes/Docker)
+- `/health/live` - Liveness probe (for Kubernetes/Docker)
+- **Checks**: EF Core DbContext connectivity test
+
+**6. Migration from BackgroundService:**
+- **Before**: `services.AddHostedService<WeeklyNetworkCommissionWorker>()` (Timer-based, runs on single server)
+- **After**: `services.AddScoped<WeeklyCommissionJob>()` (Hangfire-managed, distributed-ready)
+- **Old Worker**: Disabled in `ConfigureServices.cs` (commented out)
+
+**Dashboard Access**:
+- **URL**: `http://localhost:5133/hangfire`
+- **Features**:
+  - Recurring Jobs tab: View schedule, last execution, next execution
+  - Jobs tab: History of all job executions (succeeded, failed, processing)
+  - Retries tab: Jobs that failed and are being retried
+  - Servers tab: Active Hangfire servers
+
+**Cron Schedule**:
+- `5 0 * * 0` = Every Sunday at 00:05 UTC
+- ISO 8601 week boundary (Monday start)
+- Calculates commission for **previous week** (completed week)
+
+**Production Benefits**:
+- ✅ **No Code Deploy for Schedule Changes**: Update cron expression without redeployment
+- ✅ **Job History**: Full audit trail in Hangfire SQL tables
+- ✅ **Zero Downtime**: Jobs continue during deployments (job persistence)
+- ✅ **Load Balancing**: Can run multiple Hangfire servers (distributed locks prevent double execution)
