+### روز ۸: فاز ۴ - NetworkMembershipCQ (✅ کامل)
+
+#### 1. ✅ ساختار پوشه‌ها
+- [x] ایجاد `NetworkMembershipCQ/Commands/JoinNetwork/`
+- [x] ایجاد `NetworkMembershipCQ/Commands/MoveInNetwork/`
+- [x] ایجاد `NetworkMembershipCQ/Commands/RemoveFromNetwork/`
+- [x] ایجاد `NetworkMembershipCQ/Queries/GetNetworkTree/`
+- [x] ایجاد `NetworkMembershipCQ/Queries/GetUserNetworkPosition/`
+- [x] ایجاد `NetworkMembershipCQ/Queries/GetNetworkMembershipHistory/`
+
+#### 2. ✅ Commands (9 فایل)
+**JoinNetworkCommand**:
+- [x] `JoinNetworkCommand.cs` - Add user to binary network
+  - Properties: UserId, ParentId, LegPosition (Left/Right), Reason
+  - Returns: Unit
+- [x] `JoinNetworkCommandValidator.cs`
+  - UserId, ParentId: GreaterThan(0)
+  - LegPosition: IsInEnum
+  - Reason: MaxLength(500)
+- [x] `JoinNetworkCommandHandler.cs`
+  - Check user exists and NOT already in network
+  - Check parent exists and IS in network (or Root user)
+  - Validate leg position is empty (no duplicate)
+  - Set NetworkParentId and LegPosition
+  - History: Action.Join with old/new values
+
+**MoveInNetworkCommand**:
+- [x] `MoveInNetworkCommand.cs` - Move user in network
+  - Properties: UserId, NewParentId, NewLegPosition, Reason
+- [x] `MoveInNetworkCommandValidator.cs`
+- [x] `MoveInNetworkCommandHandler.cs`
+  - Check user IS in network
+  - Check new parent exists
+  - **IsDescendant check**: Prevent circular dependencies
+    - Recursive traversal to ensure newParent is not child of user
+  - Validate new leg position is empty
+  - Update NetworkParentId and LegPosition
+  - History: Track OldParentId → NewParentId, OldLeg → NewLeg
+
+**RemoveFromNetworkCommand**:
+- [x] `RemoveFromNetworkCommand.cs` - Remove user from network
+  - Properties: UserId, Reason
+- [x] `RemoveFromNetworkCommandValidator.cs`
+- [x] `RemoveFromNetworkCommandHandler.cs`
+  - Check user IS in network
+  - Check user has NO children (must move/remove first)
+  - Set NetworkParentId = null, LegPosition = null (soft delete)
+  - Idempotent: return if already removed
+  - History: Action.Remove
+
+#### 3. ✅ Queries (12 فایل)
+**GetNetworkTreeQuery**:
+- [x] `GetNetworkTreeQuery.cs`
+  - Parameters: UserId (root), MaxDepth (1-10, default: 3)
+  - Returns: NetworkTreeDto (recursive binary tree)
+- [x] `GetNetworkTreeQueryValidator.cs`
+  - MaxDepth: InclusiveBetween(1, 10)
+- [x] `GetNetworkTreeQueryHandler.cs`
+  - Recursive BuildTree method
+  - Queries Left/Right children at each level
+  - Stops at MaxDepth to prevent large trees
+  - Returns nested structure with CurrentDepth tracking
+- [x] `NetworkTreeDto.cs`
+  - Properties: UserId, Mobile, FirstName, LastName, LegPosition
+  - CurrentDepth, LeftChild, RightChild (recursive)
+
+**GetUserNetworkPositionQuery**:
+- [x] `GetUserNetworkPositionQuery.cs`
+  - Parameter: UserId
+  - Returns: UserNetworkPositionDto
+- [x] `GetUserNetworkPositionQueryValidator.cs`
+- [x] `GetUserNetworkPositionQueryHandler.cs`
+  - User info: Mobile, Name, NetworkParentId, LegPosition
+  - Parent info: ParentMobile
+  - Children counts: TotalChildren, LeftChildCount, RightChildCount
+  - IsInNetwork flag
+- [x] `UserNetworkPositionDto.cs`
+  - 11 properties including children statistics
+
+**GetNetworkMembershipHistoryQuery**:
+- [x] `GetNetworkMembershipHistoryQuery.cs`
+  - Parameters: UserId (nullable), SortBy, PaginationState
+  - Returns: ResponseDto with pagination
+- [x] `GetNetworkMembershipHistoryQueryValidator.cs`
+- [x] `GetNetworkMembershipHistoryQueryHandler.cs`
+  - Filter by UserId (optional - shows all if null)
+  - Default sort: -Created (newest first)
+  - Pagination support
+- [x] `GetNetworkMembershipHistoryResponseDto.cs`
+  - ResponseModel: OldParentId, NewParentId, OldLeg, NewLeg
+  - Action (Join/Move/Remove), Reason, PerformedBy
+
+#### 4. ✅ Advanced Features
+- ✅ **Binary Tree Validation**:
+  - Parent-child relationship checks
+  - Leg position uniqueness (Left/Right per parent)
+  - Prevents duplicate placements
+  
+- ✅ **Circular Dependency Prevention**:
+  - IsDescendant recursive check in MoveInNetwork
+  - Prevents moving parent under its own children
+  - Maintains tree integrity
+
+- ✅ **Children Protection**:
+  - RemoveFromNetwork validates no children exist
+  - Forces move/remove children first
+  - Prevents orphaned nodes
+
+- ✅ **Soft Delete Pattern**:
+  - NetworkParentId = null (not hard delete)
+  - Preserves history and audit trail
+  - Allows re-joining network
+
+- ✅ **History Tracking**:
+  - Complete audit trail: old/new parent, old/new leg
+  - Action enum: Join, Move, Remove
+  - Reason and PerformedBy fields
+
+**Commit**: `db96a02` - feat: Add NetworkMembershipCQ - Phase 4 Application Layer
+
+**آمار**:
+- 21 فایل جدید
+- 813 خط کد اضافه شده
+- 3 Command + 3 Query + 4 DTO
+- Build: ✅ موفق (0 error, 320 warnings در Legacy code)

+     - ذخیره در NetworkWeeklyBalance
+   - `CalculateWeeklyCommissionPoolCommand` + Handler + Validator
+     - محاسبه استخر کارمزد هفتگی
+     - محاسبه ValuePerBalance = TotalPoolAmount / TotalBalances
+   - `ProcessUserPayoutsCommand` + Handler + Validator
+     - توزیع کمیسیون به کاربران بر اساس Balances
+     - ایجاد UserCommissionPayout records
+   - `RequestWithdrawalCommand` + Handler + Validator
+     - درخواست برداشت (Cash یا Diamond)
+   - `ProcessWithdrawalCommand` + Handler + Validator
+     - پردازش برداشت و به‌روزرسانی وضعیت
