+# Đánh Giá Chi Tiết Source Code CartographerSharp
+
+## 1. Tổng Quan
+**CartographerSharp** là một bản port (chuyển đổi) đầy đủ và trung thành của hệ thống Google Cartographer sang ngôn ngữ C# (.NET 10.0). Dự án được cấu trúc bài bản, thể hiện sự hiểu biết sâu sắc về cả thuật toán SLAM và các tính năng hiện đại của .NET.
+
+### Điểm Nổi Bật
+- **Technology Stack**: Sử dụng .NET 10.0 (Preview), tối ưu hiệu năng.
+- **Dependency**: Tích hợp chặt chẽ với `CeresSharp` cho các bài toán tối ưu phi tuyến.
+- **Kiến Trúc**: Giữ nguyên mô hình Frontend-Backend mạnh mẽ của bản gốc.
+- **Tính Năng**: Hỗ trợ đầy đủ các thuật toán Scan Matching (Real-time Correlative, Fast Correlative, Ceres Scan Matcher).
+
+## 2. Kiến Trúc Hệ Thống
+
+Hệ thống tuân theo kiến trúc module hóa cao, tách biệt rõ ràng giữa việc xử lý dữ liệu cảm biến (Local SLAM) và tối ưu hóa toàn cục (Global SLAM).
+
+```mermaid
+graph TB
+    subgraph "Core Interfaces"
+        MapBuilder["IMapBuilder (Orchestrator)"]
+        TrajBuilder["ITrajectoryBuilder (Frontend)"]
+        PoseGraph["IPoseGraph (Backend)"]
+    end
+
+    subgraph "Mapping Implementation"
+        LocalScanMatcher["Scan Matchers (Ceres/Correlative)"]
+        Submaps["Submaps (Grid2D/3D)"]
+        Optimization["OptimizationProblem (Ceres)"]
+    end
+
+    Sensors[/"Sensors (Lidar, IMU, Odom)"/] --> TrajBuilder
+    
+    TrajBuilder -->|"Scan Matching"| LocalScanMatcher
+    LocalScanMatcher -->|"Update"| Submaps
+    LocalScanMatcher -->|"Node & Constraints"| PoseGraph
+    
+    PoseGraph -->|"Loop Closure"| Optimization
+    Optimization -->|"Optimized Pose"| MapBuilder
+```
+
+### Luồng Dữ Liệu (Data Flow)
+
+1.  **Input**: Dữ liệu từ Lidar, IMU, Odometry được đưa vào qua `ITrajectoryBuilder`.
+2.  **Frontend (Local SLAM)**: 
+    - `LocalTrajectoryBuilder2D` xử lý dữ liệu thô.
+    - `VoxelFilter` lọc nhiễu và giảm kích thước dữ liệu.
+    - `ScanMatching` (sử dụng `CeresScanMatcher2D` hoặc `RealTimeCorrelativeScanMatcher2D`) tìm vị trí robot cục bộ bằng cách khớp với Submap hiện tại.
+    - Kết quả là một `Node` mới trong đồ thị quỹ đạo.
+3.  **Backend (Global SLAM)**:
+    - `PoseGraph2D` quản lý đồ thị các pose.
+    - Khi phát hiện Loop Closure (quay lại chốn cũ), `ConstraintBuilder` sẽ tạo ràng buộc mới.
+    - `OptimizationProblem2D` sử dụng `CeresSharp` để giải bài toán tối ưu toàn cục, giảm sai số tích lũy.
+
+## 3. Phân Tích Cấu Trúc Mã Nguon
+
+Thư mục `srcs\RobotNet10\RobotApp\Communication\CartographerSharp` được tổ chức rất rõ ràng:
+
+| Thư mục | Vai trò | Chi tiết |
+|---------|---------|----------|
+| `Mapping` | **Core Logic** | Chứa `MapBuilder`, `PoseGraph` và các interface chính. |
+| `Mapping/Internal` | **Implementation** | Các thuật toán chi tiết, ẩn giấu khỏi API public. |
+| `Mapping/Internal/2D/ScanMatching` | **Thuật toán SLAM** | Chứa `FastCorrelativeScanMatcher`, `CeresScanMatcher` - trái tim của Local SLAM. |
+| `Sensor` | **Data Types** | `PointCloud`, `ImuData`, `OdometryData`, `VoxelFilter`. |
+| `IO` | **Serialization** | Đọc/Ghi file `.pbstream` (tương thích Protocol Buffers). |
+| `Common` | **Utilities** | Math helpers, Time conversion. |
+
+## 4. Đánh Giá Chất Lượng Code
+
+### Ưu Điểm
+1.  **Modern C#**: Sử dụng các tính năng mới nhất của C# như `record`, `nullable reference types`, `System.Text.Json`.
+2.  **Hiệu Năng**: 
+    - Sử dụng `unsafe` code block ở những nơi cần thiết (ví dụ: thao tác pointer trong xử lý ảnh hoặc math loop) để đạt hiệu năng gần với C++.
+    - Sử dụng `System.Numerics.Vector3` để tận dụng SIMD.
+3.  **Clean Code**:
+    - Tên biến và hàm rõ nghĩa, tuân thủ chuẩn naming convention của C#.
+    - Comments đầy đủ, đặc biệt là các phần thuật toán phức tạp (như trong `VoxelFilter.cs`).
+4.  **Tương Thích**:
+    - Hệ thống Serialization/Deserialization qua ProtoBuf đảm bảo có thể load/save map tương thích với các tool khác trong hệ sinh thái Cartographer.
+
+### Nhược Điểm / Cần Lưu Ý
+1.  **Độ Phức Tạp Cao**: Do port từ C++ nên một số cấu trúc (như `Delegate` hay `Callback`) có thể hơi phức tạp đối với người mới làm quen C# thuần túy.
+2.  **Dependency**: Phụ thuộc vào native library `Ceres Solver` (thông qua `CeresSharp`). Việc deploy cần đảm bảo có đủ native binaries cho OS tương ứng (Windows/Linux).
+
+## 5. Chi Tiết Các Component Quan Trọng
+
+### 5.1. Scan Matching (`Mapping/Internal/2D/ScanMatching`)
+Đây là phần ấn tượng nhất. Source code đã implement đầy đủ:
+- **`RealTimeCorrelativeScanMatcher2D`**: Dùng cho local slam nhanh, tìm kiếm trong cửa sổ nhỏ.
+- **`FastCorrelativeScanMatcher2D`**: Dùng cho Loop Closure, tìm kiếm trên toàn map sử dụng Branch & Bound.
+- **`CeresScanMatcher2D`**: Tinh chỉnh pose (refinement) với độ chính xác sub-pixel.
+
+### 5.2. Pose Graph (`Mapping/PoseGraph.cs`)
+- Implement logic `Trimmer` để giới hạn kích thước map (xóa bớt submap cũ nếu cần).
+- Xử lý đa luồng (Multi-threading) cho việc tính toán Constraint (rất quan trọng cho hiệu năng Real-time).
+
+## 6. Kết Luận
+Source code `CartographerSharp` là một tài sản giá trị, chất lượng cao. Nó không chỉ là một wrapper đơn giản mà là một bản implement thực sự của các thuật toán SLAM phức tạp trên nền tảng .NET.
+
+**Khuyến nghị**:
+- Nên duy trì unit test (nếu có) để đảm bảo tính đúng đắn khi nâng cấp .NET version.
+- Cần chú ý phần `Interop` với `CeresSharp` khi deploy lên các môi trường khác nhau (Docker, Linux ARM64, v.v.).

+**Key Implementation Details**:
+- **Callback marshalling**: Similar to `AutoDiffCostFunction` pattern
+  - Marshal `IntPtr` → `double[]` arrays
+  - Call C# delegate
+  - Marshal result arrays back to `IntPtr`
+- **Memory management**: 
+  - Pin `GCHandle` cho wrapper object
+  - Pin `GCHandle` cho native callbacks
+  - Cleanup trong `Dispose()` (not finalizer)
+- **Error handling**: 
+  - Validate parameters trong constructor
+  - Throw `CeresException` on failure
+  - Handle `IntPtr.Zero` return from native
+- **Ownership**: 
+  - Problem owns manifold when set via `SetManifold()`
+  - But we need to cleanup callbacks (GCHandles) when AutoDiffManifold is disposed
+  - Similar pattern to `AutoDiffCostFunction`
+
+**Example Structure** (reference from AutoDiffCostFunction):
+```csharp
+public sealed class AutoDiffManifold : Manifold
+{
+    private readonly GCHandle _wrapperHandle;
+    private readonly int _ambientSize;
+    private readonly int _tangentSize;
+
+    public delegate bool PlusOperation(double[] x, double[] delta, double[] xPlusDelta);
+    public delegate bool MinusOperation(double[] y, double[] x, double[] yMinusX);
+
+    public AutoDiffManifold(
+        int ambientSize,
+        int tangentSize,
+        PlusOperation plus,
+        MinusOperation minus)
+        : base(CreateHandle(ambientSize, tangentSize, plus, minus, out var wrapperHandle))
+    {
+        _ambientSize = ambientSize;
+        _tangentSize = tangentSize;
+        _wrapperHandle = wrapperHandle;
+    }
+
+    private static ManifoldHandle CreateHandle(...)
+    {
+        // Similar to AutoDiffCostFunction.CreateHandle()
+        // 1. Create CallbackWrapper
+        // 2. Pin với GCHandle
+        // 3. Create native callbacks
+        // 4. Pin native callbacks
+        // 5. Call ceres_wrapper_create_autodiff_manifold()
+        // 6. Return ManifoldHandle
+    }
+
+    protected override void Dispose(bool disposing)
+    {
+        if (disposing && _wrapperHandle.IsAllocated)
+        {
+            base.Dispose(disposing);
+            _wrapperHandle.Free();
+            // Free native callback handles from wrapper
+        }
+    }
+
+    private class CallbackWrapper
+    {
+        public PlusOperation Plus = null!;
+        public MinusOperation Minus = null!;
+        public int AmbientSize;
+        public int TangentSize;
+        public GCHandle[]? NativeCallbackHandles;
+    }
+}

+## 📝 Notes
+
+### Implementation Considerations
+
+1. **Memory Management**:
+   - Problem owns manifold when set via `SetManifold()`
+   - But we need to cleanup callbacks (GCHandles) when AutoDiffManifold is disposed
+   - Similar pattern to `AutoDiffCostFunction`
+
+2. **Jacobian Computation**:
+   - ✅ **Đã implement trong C wrapper** với numeric differentiation (epsilon = 1e-8)
+   - ✅ `PlusJacobian`: Finite difference w.r.t. `delta` parameter
+   - ✅ `MinusJacobian`: Finite difference w.r.t. first argument `y`
+   - ✅ **Không cần implement trong C#** - C wrapper đã handle
+
+3. **Error Handling**:
+   - ✅ **C wrapper**: Đã có error handling (try-catch, NULL checks)
+   - [ ] **C# wrapper**: Validate parameters trong constructor
+   - [ ] **C# wrapper**: Throw `CeresException` on failure
+   - [ ] **C# wrapper**: Handle `IntPtr.Zero` return from native
+
+4. **Testing Strategy**:
+   - ✅ **C wrapper**: Đã test với Euclidean manifold
+   - [ ] **C# wrapper**: Test với simple manifolds (Euclidean) - similar to C tests
+   - [ ] **C# wrapper**: Test với ConstantYawQuaternion (Cartographer use case)
+   - [ ] **C# wrapper**: Verify memory management (GCHandle cleanup)
+   - [ ] **C# wrapper**: Test với Problem integration

+
+## 📝 Implementation Notes
+
+### C Wrapper Implementation Details ✅ **COMPLETE**
+
+**File**: `ipc/CeresWrapper/ceres_wrapper.cc` lines 752-904
+
+**Key Features**:
+- ✅ `AutoDiffManifoldWrapper` class extends `ceres::Manifold`
+- ✅ `Plus()` và `Minus()` call C callbacks directly
+- ✅ `PlusJacobian()`: Numeric differentiation w.r.t. `delta` (epsilon = 1e-8)
+- ✅ `MinusJacobian()`: Numeric differentiation w.r.t. first argument `y` (epsilon = 1e-8)
+- ✅ Error handling với try-catch
+- ✅ Memory management với `std::unique_ptr` và custom deleter
+
+**Jacobian Computation** (đã implement trong C wrapper):
+- **PlusJacobian**: Finite difference `(Plus(x, perturbed_delta) - Plus(x, 0)) / epsilon`
+  - Perturb từng element của `delta`
+  - Compute finite difference cho mỗi column
+- **MinusJacobian**: Finite difference `(Minus(perturbed_y, x) - Minus(x, x)) / epsilon`
+  - Perturb từng element của `y` (first argument)
+  - Compute finite difference cho mỗi column
+- Epsilon: `1e-8` (sufficient for most use cases)
+
+**API Signature** (từ `ceres_wrapper.h`):
+```c
+// Callback types
+typedef int (*ceres_autodiff_manifold_plus_t)(
+    void* user_data,
+    const double* x,              // ambient_size elements
+    const double* delta,          // tangent_size elements
+    double* x_plus_delta);        // ambient_size elements (output)
+
+typedef int (*ceres_autodiff_manifold_minus_t)(
+    void* user_data,
+    const double* y,              // ambient_size elements
+    const double* x,              // ambient_size elements
+    double* y_minus_x);          // tangent_size elements (output)
+
+// Functions
+CERES_WRAPPER_EXPORT ceres_manifold_t* ceres_wrapper_create_autodiff_manifold(
+    int ambient_size,
+    int tangent_size,
+    ceres_autodiff_manifold_plus_t plus_callback,
+    ceres_autodiff_manifold_minus_t minus_callback,
+    void* user_data);
+
+CERES_WRAPPER_EXPORT void ceres_wrapper_free_autodiff_manifold(ceres_manifold_t* manifold);
+```
+
+**Test Coverage** (từ `ceres_wrapper_test.c`):
+- ✅ Create/destroy AutoDiff manifold
+- ✅ Verify dimensions (ambient_size, tangent_size)
+- ✅ Test Plus operation (via Problem integration)
+- ✅ Test Problem integration (SetManifold, HasManifold, GetTangentSize)
+- ✅ Test với Euclidean manifold use case
+
+### C# Wrapper Implementation Pattern
+
+**Similar to AutoDiffCostFunction**:
+- Use `GCHandle` để pin callbacks
+- Marshal C# delegates → C callbacks
+- Handle memory cleanup trong `Dispose()`
+- Problem owns manifold, nhưng cần cleanup callbacks
+
+**Reference Implementation**:
+- ✅ `CeresSharp/Core/AutoDiffCostFunction.cs` - Pattern cho callback marshalling
+- ✅ `CeresSharp/Core/Manifold.cs` - Base class structure
+- ✅ `CeresSharp/Core/ProductManifold.cs` - Example của custom manifold với callbacks
+
+**Key Differences từ AutoDiffCostFunction**:
+- AutoDiffCostFunction: `double[][] parameters` → `double[] residuals`
+- AutoDiffManifold: `double[] x, double[] delta` → `double[] xPlusDelta` (Plus)
+- AutoDiffManifold: `double[] y, double[] x` → `double[] yMinusX` (Minus)
+- Simpler array marshalling (single arrays, not jagged arrays)
+
+**Memory Management Pattern**:
+```csharp
+// 1. Create CallbackWrapper object
+var wrapper = new CallbackWrapper { Plus = plus, Minus = minus, ... };
+
+// 2. Pin wrapper
+var wrapperHandle = GCHandle.Alloc(wrapper);
+
+// 3. Create native callbacks (marshal C# → C)
+var plusCallback = new CeresNative.CeresAutoDiffManifoldPlus((userData, x, delta, xPlusDelta) =>
+{
+    var handle = GCHandle.FromIntPtr(userData);
+    var wrapperObj = (CallbackWrapper)handle.Target!;
+    
+    // Marshal arrays
+    var xArray = new double[wrapperObj.AmbientSize];
+    var deltaArray = new double[wrapperObj.TangentSize];
+    var xPlusDeltaArray = new double[wrapperObj.AmbientSize];
+    
+    Marshal.Copy(x, xArray, 0, wrapperObj.AmbientSize);
+    Marshal.Copy(delta, deltaArray, 0, wrapperObj.TangentSize);
+    
+    // Call C# delegate
+    var success = wrapperObj.Plus(xArray, deltaArray, xPlusDeltaArray);
+    
+    // Marshal result back
+    if (success)
+        Marshal.Copy(xPlusDeltaArray, 0, xPlusDelta, wrapperObj.AmbientSize);
+    
+    return success ? 1 : 0;
+});
+
+// 4. Pin native callbacks
+var plusHandle = GCHandle.Alloc(plusCallback);
+var minusHandle = GCHandle.Alloc(minusCallback);
+
+// 5. Call native function
+var handle = CeresNative.ceres_wrapper_create_autodiff_manifold(...);
+
+// 6. Store handles for cleanup
+wrapper.NativeCallbackHandles = new[] { plusHandle, minusHandle };
+```

+# CeresSharp Integration Tasks - Chi tiết Công việc
+
+## 📋 Tổng quan
+
+Tài liệu này mô tả **cụ thể** những gì cần làm để tích hợp CeresSharp vào CartographerSharp, hoàn thiện các components còn thiếu.
+
+## ✅ Trạng thái hiện tại
+
+- **CeresSharp**: ✅ Đã có sẵn (100% complete - 216+ APIs)
+- **Ceres Solver Version**: 2.2.0
+- **CartographerSharp**: ⏳ Đang chờ CeresSharp integration
+
+## 🎯 Nơi Triển Khai: **CartographerSharp**
+
+**Quan trọng**: Tất cả implementation sẽ được làm **trong CartographerSharp**, không phải CeresSharp.
+
+### Lý do:

+- **Scan Matching**: ~40% code sử dụng Ceres
+- **Pose Graph Optimization**: ~45% code sử dụng Ceres
+- **IMU Extrapolation**: ~10% code sử dụng Ceres
+- **Utilities**: ~5% (configuration, helper classes)
+
+### Số lượng Cost Functions:

+
+### Solver Types:
+- **DENSE_QR**: Scan matching (nhỏ, real-time)
+- **SPARSE_SCHUR**: Pose graph optimization (lớn, hiệu quả)
+
+---
+
+## ⚠️ Thách thức khi Chuyển đổi sang C#
+
+### 1. **Core APIs phải có:**
+- ✅ `Problem` - Container cho optimization
+- ✅ `Solver` - Nonlinear solver
+- ✅ `AutoDiffCostFunction` - Automatic differentiation
+- ✅ `CostFunction` - Base class
+- ✅ `LossFunction` (HuberLoss) - Robust loss
+- ✅ `Parameterization` (QuaternionParameterization) - Constraint handling
+- ✅ `BiCubicInterpolator` - Grid interpolation
+
+### 2. **Features quan trọng:**
+- **Dynamic residuals** - Số lượng points trong point cloud không cố định
+- **Multi-parameter blocks** - Nhiều poses cùng optimize
+- **Parameter constraints** - Fix certain parameters
+- **Robust optimization** - Huber loss cho outliers
+
+### 3. **Performance Requirements:**
+- Real-time scan matching (milliseconds)
+- Large-scale pose graph optimization (hàng nghìn nodes)
+- Efficient sparse solvers cho large problems
+
+---
+
+## 💡 Kết luận
+
+Ceres Solver là **thành phần CORE không thể thiếu** của Cartographer:
+
+1. **Scan Matching**: Cần cho local SLAM - tìm vị trí robot
+2. **Pose Graph Optimization**: Cần cho global SLAM - optimize toàn bộ map
+3. **IMU Integration**: Cần cho pose extrapolation
+
+**Không có Ceres Solver = Không có SLAM algorithm**
+
+Khi chuyển đổi sang C#, cần:
+- ✅ Quyết định phương án thay thế sớm
+- ✅ Đảm bảo có đầy đủ APIs cần thiết
+- ✅ Test performance để đảm bảo real-time requirements
+

+---
+
+### 2. **Google Glog (glog)** ⭐⭐⭐
+
+**C/C++**: Google logging library
+- `LOG(INFO)`, `LOG(WARNING)`, `LOG(ERROR)`, `LOG(FATAL)`
+
+**Thay thế C#:**
+- ✅ **Microsoft.Extensions.Logging.ILogger** + **NLog**
+  - `ILogger` là abstraction interface (dependency injection friendly)
+  - NLog là implementation provider với nhiều features
+
+**Ví dụ chuyển đổi:**
+```cpp
+// C++
+LOG(INFO) << "Message: " << value;
+LOG(ERROR) << "Error occurred";
+```
+
+```csharp
+// C#
+_logger.LogInformation("Message: {Value}", value);
+_logger.LogError("Error occurred");
+
+// Constructor injection
+public class SomeClass
+{
+    private readonly ILogger<SomeClass> _logger;
+    
+    public SomeClass(ILogger<SomeClass> logger)

+    
+    public MapBuilder(MapBuilderOptions options)
+    {
+        _options = options ?? throw new ArgumentNullException(nameof(options));
+    }
+}
+
+// Sử dụng

+**C/C++**: Nonlinear optimization library
+- Sử dụng rộng rãi cho: Scan matching (2D và 3D), Pose graph optimization, IMU-based pose extrapolation
+- **⚠️ Lưu ý quan trọng**: Cartographer source code (`refs/cartographer`) sử dụng Ceres phiên bản cũ với `LocalParameterization` API
+- **CeresSharp sử dụng Ceres 2.2.0** với `Manifold` API (thay thế `LocalParameterization`)
+
+**Thay thế C# - CeresSharp (Đã Implement):**
+
+#### ✅ Phương án Đã Chọn: CeresSharp (P/Invoke Ceres 2.2.0)
+- ✅ **Tích hợp native Ceres 2.2.0** qua P/Invoke wrapper

+| `problem.SetParameterization()` ⚠️ **DEPRECATED** | `problem.SetManifold()` | ✅ **Có sẵn** |
+
+**Chi tiết Migration:**
+- **QuaternionParameterization → QuaternionManifold**: ✅ **Trực tiếp** - Chỉ cần thay tên class
+- **AutoDiffLocalParameterization → AutoDiffManifold**: ✅ **Có sẵn** - Sử dụng callback-based API trong CeresSharp
+  - Example: `new AutoDiffManifold(ambientSize, tangentSize, plus, minus)`
+  - Sẵn sàng cho ConstantYawQuaternion use case trong Cartographer's IMU extrapolation
+- **SetParameterization() → SetManifold()**: ✅ **Trực tiếp** - Chỉ cần thay method name
+  - `SetParameterization()` đã bị **DEPRECATED** trong Ceres 2.1.0 và **REMOVED** trong Ceres 2.2.0

+var m = Matrix4x4.Identity;
+var q = Quaternion.Identity;
+var result = Vector3.Transform(v, m);
+
+// Matrix operations
+var rotation = Matrix4x4.CreateRotationX(MathF.PI / 4);
+var translation = Matrix4x4.CreateTranslation(new Vector3(10, 20, 30));
+var transform = rotation * translation;
+```

+    "MinRange": 0.5,
+    "NumAccumulatedRangeData": 1,
+    "VoxelFilterSize": 0.025
+  }
+}
+```
+
+**C# Class:**

+{
+    [JsonPropertyName("max_range")]
+    public double MaxRange { get; set; }
+    
+    [JsonPropertyName("min_range")]
+    public double MinRange { get; set; }
+

+    
+    [JsonPropertyName("voxel_filter_size")]
+    public double VoxelFilterSize { get; set; }
+}
+
+// Loading

+
+**Thay thế C# - Manual Conversion:**
+- ✅ **Chuyển đổi trực tiếp** (không dùng code generation)
+  - **Message Proto** → **C# struct/class** với attributes cho serialization
+  - **Service Proto** → **C# interface**
+  - Sử dụng `System.Text.Json` hoặc `BinaryFormatter` cho serialization
+
+**Ví dụ:**
+
+**Proto Message:**
+```protobuf
+message Rigid2d {
+  double translation_x = 1;
+  double translation_y = 2;
+  double rotation = 3;
+}
+```
+
+**C# Struct:**
+```csharp
+public struct Rigid2d
+{
+    [JsonPropertyName("translation_x")]
+    public double TranslationX { get; set; }
+    
+    [JsonPropertyName("translation_y")]
+    public double TranslationY { get; set; }
+

+
+## 💡 Ghi chú Quan trọng
+
+### Cho AI Agent / Developers
+
+1. **Luôn tham chiếu source code C/C++** trong `refs/cartographer/` khi chuyển đổi
+2. **Giữ nguyên logic và thuật toán**, chỉ thay đổi syntax và patterns theo C#
+3. **Ưu tiên type safety** - sử dụng strong typing của C#
+4. **Sử dụng async/await** cho I/O operations
+5. **Xem xét memory management** - C# garbage collection vs C++ manual
+6. **Test từng module** sau khi chuyển đổi
+
+### Key Decisions
+
+1. **Ceres Solver** - ✅ **Đã quyết định**: Sử dụng **CeresSharp** (P/Invoke Ceres 2.2.0)
+   - ✅ **Đã implement đầy đủ** - 220+ APIs (bao gồm AutoDiffManifold), 99%+ test coverage
+   - ✅ **100 tests, tất cả pass** - Comprehensive test coverage
+   - ✅ **Production ready** - Đã fix memory management issues
+   - ✅ **API tương thích cao** - Dễ dàng convert từ C++ code
+   - ✅ **AutoDiffManifold đã hoàn thành** - Sẵn sàng cho Cartographer integration
+   - ⚠️ **Migration cần thiết**: Từ `LocalParameterization` (Ceres cũ) → `Manifold` (Ceres 2.2.0)
+     - ✅ **Tất cả APIs đã có sẵn** - QuaternionManifold, AutoDiffManifold, SetManifold()
+   - 📋 **Chi tiết**: Xem `CERES_READINESS_EVALUATION.md`, `CERES_USAGE.md`, và `AUTODIFF_MANIFOLD_IMPLEMENTATION_TASKS.md`
+
+2. **Ưu tiên Standard Library** - Trừ Ceres Solver, tất cả dependencies khác nên ưu tiên standard .NET libraries trước khi dùng third-party packages.
+
+3. **Protocol Buffers** - Manual conversion (proto → structs/interfaces) giúp code C# native hơn, không phụ thuộc vào Google.Protobuf package.
+
+4. **Lua Configuration** - Chuyển sang JSON với System.Text.Json (standard library) sẽ đơn giản và type-safe hơn.
+
+5. **Google gflags** - Vì CartographerSharp là Library, không cần command-line parsing. Dùng constructor parameters và configuration objects.
+
+6. **Cairo → SkiaSharp** - Đã quyết định sử dụng SkiaSharp thay cho Cairo cho tất cả visualization tasks. SkiaSharp cung cấp modern API và cross-platform support tốt hơn.
+
+7. **Performance** - SLAM là real-time, cần performance cao. .NET 10 cung cấp:
+   - SIMD improvements trong System.Numerics
+   - Better vectorization và JIT optimizations
+   - Source generators cho JSON serialization
+   - Xem xét unsafe code nếu cần performance cực cao

+

+
+## 🐛 Vấn đề đã gặp và Giải pháp
+
+### 1. Lỗi CS0102: Duplicate Definition
+**Vấn đề**: Compiler báo lỗi duplicate definition cho `Translation` và `Rotation` properties trong `Rigid2d`, `Rigid2f`, `Rigid3d`, `Rigid3f`.
+
+**Nguyên nhân**: Static methods `Translation()` và `Rotation()` trùng tên với properties `Translation` và `Rotation`, gây conflict trong compiler.
+
+**Giải pháp**: Đổi tên static factory methods:
+- `Translation()` → `FromTranslation()`
+- `Rotation()` → `FromRotation()`
+
+**Files đã sửa**:
+- `Transform/Rigid2.cs`
+- `Transform/Rigid3.cs`
+
+### 2. Lỗi CS0234: Namespace Conflict với Math
+**Vấn đề**: Compiler không tìm thấy `Math.PI` và `Math.Atan2` trong `MathUtils.cs`.
+
+**Nguyên nhân**: Namespace `CartographerSharp.Common.Math` conflict với `System.Math`.
+
+**Giải pháp**: Sử dụng fully qualified name `System.Math.PI` và `System.Math.Atan2`.
+
+**Files đã sửa**:
+- `Common/Math/MathUtils.cs`
+
+### 3. Lỗi CS0122: Inaccessible Method
+**Vấn đề**: `Task.cs` không thể gọi `NotifyDependenciesCompleted` vì method là `protected`.
+
+**Nguyên nhân**: `NotifyDependenciesCompleted` được định nghĩa là `protected abstract` trong `ThreadPoolInterface`, nhưng `Task` cần gọi từ bên ngoài class hierarchy.
+
+**Giải pháp**: Đổi access modifier từ `protected` sang `internal`:
+- `ThreadPoolInterface.NotifyDependenciesCompleted` → `internal abstract`
+- `ThreadPool.NotifyDependenciesCompleted` → `internal override`
+
+**Files đã sửa**:
+- `Common/Threading/ThreadPool.cs`
+
+### 4. Lỗi CS1061/CS1503: Nullable Struct Handling trong ProtoStreamDeserializer
+**Vấn đề**: Compiler báo lỗi `'SerializedData' does not contain a definition for 'HasValue'` và `cannot convert from 'out SerializedData?' to 'out SerializedData'` khi xử lý nullable structs.
+
+**Nguyên nhân**: Khi sử dụng `out var` với generic method `ReadProto<T>(out T? proto)`, compiler không tự động infer nullable struct type (`SerializedData?`) cho struct types.
+
+**Giải pháp**: Sử dụng `ReadNextSerializedData()` method pattern thay vì gọi `ReadProto` trực tiếp trong constructor, vì `ReadNextSerializedData` có explicit `out SerializedData?` parameter type.
+
+**Files đã sửa**:
+- `IO/ProtoStreamDeserializer.cs`
+
+### 5. Lỗi CS0117: Naming Conflict giữa PoseGraph Class và Proto Struct
+**Vấn đề**: Compiler không thể resolve `PoseGraph.FromProto()` vì có naming conflict giữa `CartographerSharp.Mapping.PoseGraph` (class) và `CartographerSharp.Proto.Mapping.PoseGraph` (struct).
+
+**Nguyên nhân**: `using CartographerSharp.Proto.Mapping;` statement gây conflict khi reference `PoseGraph` trong cùng namespace.
+
+**Giải pháp**: Sử dụng reflection để gọi static method `FromProto` từ `CartographerSharp.Mapping.PoseGraph` class để tránh naming conflict.
+
+**Files đã sửa**:
+- `Mapping/MapBuilder.cs`

+
+### ✅ Tối ưu Performance - Thay thế Tuple bằng Array2i Struct
+- **Vấn đề**: Ban đầu sử dụng `(int x, int y)` tuple để thay thế `Eigen::Array2i`

+  - Operators (+, -, *, /, <, <=, >, >=, ==, !=)
+  - Methods (ToVector2, FromVector2, Deconstruct)
+  - Zero static property
+- **Lợi ích**:
+  - Tối ưu performance hơn tuple (struct value type)
+  - Rõ ràng về semantic (tương đương với Eigen)
+  - Dễ dàng mở rộng với operators và methods

+
+### Design Decisions
+1. **Generic Math Functions**: Sử dụng generic constraints (`IFloatingPoint<T>`, `IMultiplyOperators<T>`) để hỗ trợ nhiều kiểu số
+2. **Struct over Class**: Sử dụng `struct` cho `Rigid2d/f`, `Rigid3d/f` để tối ưu performance
+3. **Implicit Operators**: Sử dụng implicit operators trong proto structs để seamless conversion với `System.Numerics` types
+4. **Thread Safety**: Sử dụng `lock` và `ConcurrentQueue` cho thread-safe operations

+
+### 1.1 Input Processing
+- **Time Conversion**: Mọi timestamp đều được chuyển về `ticks` (C# `DateTime.Ticks` hoặc Universal Time).
+- **Multiple Sensors**: Dữ liệu từ nhiều Lidar được hợp nhất (merged) dựa trên thời gian nếu chúng được cấu hình trong cùng một trajectory.
+
+### 1.2 Extrapolation
+Trước khi scan matching, hệ thống cần một "dự đoán" vị trí robot.
+- `PoseExtrapolator` sử dụng:
+  - **IMU**: Để dự đoán hướng (rotation) chính xác.
+  - **Odometry**: Để dự đoán dịch chuyển (translation).
+  - **Constant Velocity Model**: Nếu không có Odom, giả định vận tốc không đổi từ các scan trước.
+
+---
+
+## 2. Cơ Chế Local SLAM
+
+Local SLAM chịu trách nhiệm xác định vị trí robot tức thời so với submap hiện tại.
+
+### 2.1 Voxel Filtering
+Giảm số lượng điểm để tăng tốc độ tính toán.
+- `VoxelFilterSize`: Kích thước cạnh của voxel lập phương (ví dụ 0.05m).
+- Mỗi voxel chỉ giữ lại 1 điểm đại diện (thường là tâm hoặc điểm đầu tiên).
+
+### 2.2 Scan Matching Logic
+CartographerSharp sử dụng chiến lược 2 bước:
+
+1. **Real-Time Correlative Scan Matcher (CSM)**:
+   - **Mục đích**: Tìm kiếm trong một vùng lân cận (Search Window) để tránh rơi vào cực trị địa phương (local minima).
+   - **Cách hoạt động**: Thử các tư thế (poses) khác nhau xung quanh pose dự đoán, tính điểm khớp với grid map.
+   - **Ưu điểm**: Mạnh mẽ, không cần gradient.
+   - **Nhược điểm**: Chậm nếu Search Window lớn.
+
+2. **Ceres Scan Matcher**:
+   - **Mục đích**: Tinh chỉnh kết quả của CSM để đạt độ chính xác cao nhất (sub-pixel).
+   - **Cách hoạt động**: Giải bài toán tối ưu phi tuyến (Non-linear Least Squares).
+   - **Cost Function**: $J = w_{map} * (1 - P(M, T\cdot p))^2 + w_{trans} * ||T_{trans}||^2 + w_{rot} * ||T_{rot}||^2$
+     - $P(M, x)$: Xác suất tại vị trí x trên bản đồ M.
+     - $T$: Biến đổi (pose) cần tìm.
+
+### 2.3 Submaps
+- Dữ liệu được chèn vào **Probability Grid**.
+- Mỗi ô (cell) lưu trữ xác suất có vật cản (odds).
+- Một `ActiveSubmaps` giữ 2 submap cùng lúc:
+  1. Old Submap: Đang hoàn thiện, dùng để scan match.
+  2. New Submap: Đang xây dựng, để đảm bảo sự liên tục khi Old Submap hoàn thành.
+
+---
+
+## 3. Cơ Chế Global SLAM
+
+### 3.1 Constraints
+Ràng buộc (Constraint) là "lò xo" kết nối các node và submap.
+- **Intra-submap constraints**: Tạo ra tự động khi node được thêm vào submap. Giữ cho quỹ đạo liền mạch.
+- **Inter-submap constraints (Loop Closure)**: Kết nối node hiện tại với submap *cũ* đã đi qua từ lâu.
+
+### 3.2 Optimization Problem
+Backend giải bài toán tối ưu hóa đồ thị khổng lồ (Sparse Pose Graph Optimization).
+- **Biến (Variables)**: Poses của các Submap và Nodes.
+- **Mục tiêu**: Giảm thiểu năng lượng của các "lò xo" (constraints).
+
+---
+
+## 4. Giải Thích Tham Số Cấu Hình
+
+Dưới đây là các tham số quan trọng nhất trong `TrajectoryBuilder2DOptions` và `PoseGraphOptions`.
+
+### 4.1 TrajectoryBuilder2DOptions
+
+| Tham Sô | Giá Trị Mẫu | Ý Nghĩa | Tác Động Tuning |
+|---------|-------------|---------|-----------------|
+| `MinRange` | 0.3 | Bỏ qua điểm quá gần | Tăng nếu robot thấy "thân mình". |
+| `MaxRange` | 30.0 | Bỏ qua điểm quá xa | Giảm nếu môi trường nhiễu ở xa. |
+| `MinZ`/`MaxZ` | -0.8 / 2.0 | Giới hạn chiều cao (cho 3D -> 2D) | Quan trọng để loại bỏ sàn nhà/trần nhà. |
+| `VoxelFilterSize` | 0.025 | Kích thước lưới lọc | Tăng (0.05) giảm CPU, giảm (0.01) tăng chi tiết. |
+| `UseImu` | true | Bật/Tắt IMU | Luôn để `true` nếu có IMU. |
+
+### 4.2 CeresScanMatcherOptions2D
+
+| Tham Số | Giá Trị Mẫu | Ý Nghĩa |
+|---------|-------------|---------|
+| `OccupiedSpaceWeight` | 1.0 | Trọng số khớp bản đồ |
+| `TranslationWeight` | 10.0 | Trọng số tin vào pose dự đoán (vị trí) | Tăng nếu scan matching hay bị trượt dọc hành lang. |
+| `RotationWeight` | 40.0 | Trọng số tin vào pose dự đoán (hướng/IMU) | Rất quan trọng. Tăng cao nếu IMU tốt. |
+
+### 4.3 PoseGraphOptions
+
+| Tham Số | Giá Trị Mẫu | Ý Nghĩa |
+|---------|-------------|---------|
+| `OptimizeEveryNNodes` | 90 | Tần suất chạy Global SLAM | 0 = Tắt Global SLAM. Giảm số này = Chạy thường xuyên hơn (CPU cao). |
+| `ConstraintBuilderOptions.MinScore` | 0.55 | Ngưỡng tin cậy Loop Closure | Giảm -> Nhạy hơn (dễ loop close sai). Tăng -> Khắt khe hơn. |
+| `ConstraintBuilderOptions.SamplingRatio` | 0.3 | Tỉ lệ node để check loop closure | 1.0 = Check toàn bộ (chậm). 0.1 = Check 10%. |
+

+
+## 5. Mở Rộng & Tùy Biến
+
+### 5.1 Thêm Custom Cost Function
+Bạn có thể định nghĩa luật tối ưu riêng bằng cách kế thừa `CostFunction` từ `CeresSharp`.
+
+Ví dụ: Muốn robot luôn bám sát tường phải (Right Wall Following Constraint).
+
+```csharp
+public class WallFollowCostFunction : CostFunction
+{
+    private readonly double _targetDistance;
+    
+    public WallFollowCostFunction(double targetDistance)
+    {
+        _targetDistance = targetDistance;
+        // Output: 1 residual. Input: 1 parameter block (Pose 3D: [x, y, theta])
+        SetNumResiduals(1);
+        AddParameterBlock(3);
+    }
+

+
+### 5.2 Xử Lý Dữ Liệu GPS
+Để tích hợp GPS (FixedFramePose):
+1. Cấu hình `MapBuilder` dùng `FixedFramePoseData`.
+2. Định nghĩa `NavSatFix` -> `FixedFramePoseData` converter.
+3. Chú ý: GPS pose cần được chuyển đổi sang hệ tọa độ của bản đồ (thường là UTM hoặc Local Tangent Plane).

+
+## 6. Performance Tuning Checklist
+
+- [ ] **Lidar Rate**: 5Hz - 20Hz là lý tưởng. Quá nhanh (>100Hz) sẽ làm nghẽn hàng đợi TrajectoryBuilder.
+- [ ] **Data Compression**: Dữ liệu `TimedPointCloudData` khá nặng. CartographerSharp truyền tham chiếu (reference) nội bộ để tránh copy.
+- [ ] **GC Pressure**: 
+  - Hạn chế tạo `new List<Vector3>` liên tục.
+  - Sử dụng `ArrayPool` nếu can thiệp sâu vào code core.

+
+## 📋 Tổng Quan
+
+TSDF (Truncated Signed Distance Function) 2D là một loại grid khác ngoài ProbabilityGrid cho 2D SLAM. TSDF lưu trữ:
+- **TSD (Truncated Signed Distance)**: Khoảng cách có dấu tới bề mặt, được truncate trong phạm vi `[-truncation_distance, truncation_distance]`
+- **Weight**: Trọng số của measurement, sử dụng để tích hợp nhiều measurements
+
+**Ưu điểm của TSDF so với ProbabilityGrid:**
+- Hỗ trợ subpixel accuracy tốt hơn
+- Xử lý uncertainty tốt hơn với weighted integration
+- Có thể extract surface với độ chính xác cao hơn

+
+2. **InsertHit method:**
+   - Calculate cells along ray (hoặc around hit)
+   - For each cell:
+     - Compute SDF distance:
+       - If `project_sdf_distance_to_scan_normal`: Project distance to scan normal
+       - Else: Use Euclidean distance from cell to hit
+     - Compute update weight:
+       - Base weight: `1.0 / distance^update_weight_range_exponent`
+       - Angle weight: Gaussian kernel based on angle between scan normal and ray
+       - Distance weight: Gaussian kernel based on distance from cell to hit
+     - Call `UpdateCell`
+
+3. **UpdateCell method:**
+   - Get current TSD and weight: `(currentTSD, currentWeight) = tsdf.GetTSDAndWeight(cell)`
+   - Compute new TSD: Weighted average
+     - `newTSD = (currentTSD * currentWeight + updateSdf * updateWeight) / (currentWeight + updateWeight)`
+     - Clamp to `[-truncation_distance, truncation_distance]`
+   - Compute new weight: `newWeight = min(currentWeight + updateWeight, maxWeight)`
+   - Call `tsdf.SetCell(cell, newTSD, newWeight)`
+
+4. **GrowAsNeeded:**
+   - Similar to ProbabilityGrid inserter
+   - Include truncation distance when calculating bounding box
+
+**Helper Functions:**
+```csharp
+// Gaussian kernel for weight calculation
+private static float GaussianKernel(float x, float sigma)
+{
+    return 1.0f / (Math.Sqrt(2.0 * Math.PI) * sigma) * 
+           Math.Exp(-0.5 * x * x / (sigma * sigma));
+}
+
+// Range weight factor: 1.0 / range^exponent
+private static float ComputeRangeWeightFactor(float range, int exponent)
+
+// RangeDataSorter: Sort points by angle from origin
+private class RangeDataSorter : IComparer<RangefinderPoint>
+```
+
+**C++ Reference:** `refs/cartographer/cartographer/mapping/internal/2d/tsdf_range_data_inserter_2d.h/cc`
+

+
+### Phase 4: Scan Matching Support
+
+#### 4.1 InterpolatedTSDF2D
+**File:** `Mapping/Internal/2D/ScanMatching/InterpolatedTSDF2D.cs`
+
+**Purpose:** Bilinear interpolation của TSDF values cho Ceres autodiff.
+
+**Methods:**
+```csharp
+public class InterpolatedTSDF2D
+{
+    private readonly TSDF2D _tsdf;
+    
+    public InterpolatedTSDF2D(TSDF2D tsdf);
+    
+    // Template method for Ceres autodiff
+    public T GetCorrespondenceCost<T>(T x, T y) where T : struct
+    {
+        // Bilinear interpolation of TSD values
+        // Returns MaxCorrespondenceCost if any interpolation point is unknown (weight == 0)
+    }
+    
+    public T GetWeight<T>(T x, T y) where T : struct
+    {
+        // Bilinear interpolation of weight values
+    }
+    
+    private Vector2 CenterOfLowerPixel(double x, double y);
+    private T InterpolateBilinear<T>(T x, T y, float x1, float y1, float x2, float y2, 
+                                      float q11, float q12, float q21, float q22);
+}
+```
+
+**Key Implementation Details:**
+- Get 4 neighboring cells: `(x1,y1)`, `(x1+1,y1)`, `(x1,y1+1)`, `(x1+1,y1+1)`
+- Check weights: If any weight == 0, return `MaxCorrespondenceCost`
+- Interpolate TSD values using bilinear interpolation
+- Works with Ceres Jet types (automatic differentiation)
+
+**C++ Reference:** `refs/cartographer/cartographer/mapping/internal/2d/scan_matching/interpolated_tsdf_2d.h`
+
+---
+
+#### 4.2 TSDFMatchCostFunction2D
+**File:** `Mapping/Internal/2D/ScanMatching/TSDFMatchCostFunction2D.cs`
+
+**Purpose:** Ceres cost function cho TSDF-based scan matching.
+
+**Methods:**
+```csharp
+public static class TSDFMatchCostFunction2D
+{
+    public static CostFunction CreateAutoDiffCostFunction(
+        double scalingFactor,
+        PointCloud pointCloud,
+        TSDF2D grid)
+    {
+        // Create InterpolatedTSDF2D
+        // Return AutoDiffCostFunction with TSDFMatchCostFunctor2D
+    }
+}
+
+private struct TSDFMatchCostFunctor2D
+{
+    private readonly double _scalingFactor;
+    private readonly PointCloud _pointCloud;
+    private readonly InterpolatedTSDF2D _interpolatedTSDF;
+    
+    public void Evaluate(double[] parameters, double[] residuals, double[][] jacobians)
+    {
+        // parameters: [x, y, cos_theta, sin_theta]
+        // Transform each point in pointCloud by pose
+        // For each transformed point:
+        //   residual = scaling_factor * interpolatedTSDF.GetCorrespondenceCost(x, y)
+        // residuals length = pointCloud.Count
+    }
+}
+```
+
+**Key Implementation Details:**
+- Transform point cloud by pose: `R * point + translation`
+- Get interpolated correspondence cost for each transformed point
+- Residual = `scaling_factor * correspondence_cost`
+- Ceres sẽ minimize tổng squared residuals
+
+**C++ Reference:** `refs/cartographer/cartographer/mapping/internal/2d/scan_matching/tsdf_match_cost_function_2d.h/cc`
+
+---
+
+#### 4.3 Update Scan Matchers
+
+**4.3.1 RealTimeCorrelativeScanMatcher2D**
+**File:** `Mapping/Internal/2D/ScanMatching/RealTimeCorrelativeScanMatcher2D.cs`
+
+**Changes needed:**
+- Line 125: Implement TSDF scoring
+```csharp
+case GridType.TSDF:
+    if (grid is TSDF2D tsdfGrid)
+    {
+        foreach (var point in discreteScan)
+        {
+            var tsd = tsdfGrid.GetTSD(proposedXYIndex);
+            // Score based on distance from zero-crossing (surface)
+            // Cells with TSD near 0 are likely to be on surface
+            candidateScore += -Math.Abs(tsd); // Closer to 0 = better
+        }
+        candidateScore /= discreteScan.Count;
+    }
+    break;
+```
+
+**Note:** TSDF scoring có thể đơn giản hơn ProbabilityGrid vì TSD gần 0 = surface.
+
+---
+
+**4.3.2 CeresScanMatcher2D**
+**File:** `Mapping/Internal/2D/ScanMatching/CeresScanMatcher2D.cs`
+
+**Changes needed:**
+- Line 112-114: Replace TODO với TSDF cost function
+```csharp
+case GridType.TSDF:
+    if (grid is TSDF2D tsdfGrid)
+    {
+        var tsdfMatchCost = TSDFMatchCostFunction2D.CreateAutoDiffCostFunction(
+            _options.OccupiedSpaceWeight / Math.Sqrt(pointCloud.Count),
+            pointCloud,
+            tsdfGrid
+        );
+        problem.AddResidualBlock(tsdfMatchCost, null, [poseParams]);
+    }
+    break;
+```
+
+---
+
+### Phase 5: Integration
+
+#### 5.1 Update RangeDataInserterOptionsProto
+**File:** `Proto/Mapping/RangeDataInserterOptionsProto.cs`
+
+**Changes needed:**
+- Uncomment and add TSDF options:
+```csharp
+[JsonPropertyName("tsdf_range_data_inserter_options_2d")]
+[JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingNull)]
+public TSDFRangeDataInserterOptions2D? TsdfRangeDataInserterOptions2D { get; set; }
+```
+
+- Update constructor to accept TSDF options
+
+---
+
+#### 5.2 Update ActiveSubmaps2D
+**File:** `Mapping/2D/ActiveSubmaps2D.cs`
+
+**Changes needed:**
+- Line 131: Replace `NotImplementedException` với TSDF2D creation
+```csharp
+GridOptions2D.GridType.Tsdf => new TSDF2D(
+    mapLimits,
+    _options.GridOptions2D.TsdfOptions?.TruncationDistance ?? 0.3f, // Default
+    _options.GridOptions2D.TsdfOptions?.MaxWeight ?? 10.0f, // Default
+    _conversionTables
+),
+```
+
+**Note:** Cần add `TsdfOptions` vào `GridOptions2D` proto nếu chưa có.
+
+---
+
+#### 5.3 Update RangeDataInserterFactory
+**File:** (tìm file tạo RangeDataInserter, có thể trong `Mapping/2D/` hoặc `Mapping/Internal/2D/`)
+
+**Changes needed:**
+- Add TSDF inserter creation:
+```csharp
+case RangeDataInserterOptions.RangeDataInserterType.TsdfInserter2D:
+    if (options.TsdfRangeDataInserterOptions2D.HasValue)
+    {
+        return new TSDFRangeDataInserter2D(options.TsdfRangeDataInserterOptions2D.Value);
+    }
+    throw new ArgumentException("TSDFRangeDataInserterOptions2D is required for TSDF inserter");
+```

+
+## ⚠️ Notes & Considerations
+
+1. **Performance:**
+   - TSDF computation phức tạp hơn ProbabilityGrid (normal estimation, weighted integration)
+   - Consider caching normal estimates nếu cần
+   - Weight calculation có thể tốn kém (Gaussian kernels)
+
+2. **Memory:**
+   - TSDF2D cần thêm `weight_cells` array (same size as correspondence_cost_cells)
+   - Memory usage ~2x so với ProbabilityGrid
+
+3. **Accuracy:**
+   - TSDF thường cho accuracy cao hơn, đặc biệt với subpixel features
+   - Normal estimation quality ảnh hưởng lớn đến SDF accuracy
+
+4. **Configuration:**
+   - `truncation_distance`: Thường 0.1-0.5m
+   - `maximum_weight`: Thường 10-50
+   - `update_weight_range_exponent`: Thường 0-2
+   - Kernel bandwidths: Cần tune cho từng sensor
+
+5. **Compatibility:**
+   - Ensure TSDF grids có thể serialize/deserialize correctly
+   - Backward compatibility với ProbabilityGrid configs

+# Luồng gọi từ Action → LiftModule → Động cơ (CiA402 Servo)
+
+## 1. liftCameraByHeight (di chuyển theo chiều cao)
+
+| Bước | Nơi gọi | Gì xảy ra |
+|------|---------|------------|
+| 1 | **LiftCameraByHeightAction** | Parse HEIGHT (m) → `_liftModule.LiftToPositionAsync(position)` |
+| 2 | **LiftModuleService.LiftToPositionAsync** | Kiểm tra Enable, _servo, limit, **State == Ready**. Set `_targetPosition = position`, gọi `_stateMachine.Fire(StartMoving)`. **Log:** `LiftModule: StartMoving fired, target position {Position}` |
+| 3 | **State machine** | Chuyển **Ready → Moving**. Trong Moving, `ExecuteOnEntry` chạy `Task.Run(...)`. **Log:** `LiftModule: Moving state entered, calling servo.MoveToPositionAsync(position=...)` |
+| 4 | **LiftModuleService (Task.Run)** | `await _servo.MoveToPositionAsync(_targetPosition, ProfileVelocity, ...)`. _servo là **ICiA402Servo** (thực tế là **CiA402Servo** từ DeviceProvider). |
+| 5 | **CiA402Servo.MoveToPositionAsync** | **Log:** `CiA402Servo[{DeviceId}]: MoveToPositionAsync position=..., velocity=... -> writing to drive`. Gọi DisableOperation → SetOperationMode(ProfilePosition) → Enable → SetProfileSpeed/Accel/Decel → **SetTargetPositionAsync** (ghi 0x607A) → **StartPositionMoveAsync** (set bit controlword). Tất cả qua **WriteObjectAsync** / **_canOpenDevice** → SDO/PDO → **động cơ**. |
+
+**Kết luận:** Có gọi xuống động cơ. Nếu thấy log `CiA402Servo[...]: MoveToPositionAsync...` thì lệnh đã tới driver và được ghi xuống drive.
+
+---
+
+## 2. homingCamera (homing camera/lift)
+
+| Bước | Nơi gọi | Gì xảy ra |
+|------|---------|------------|
+| 1 | **HomingCameraAction** | `await _liftModule.HomeAsync(...)` |
+| 2 | **LiftModuleService.HomeAsync** | **Log:** `LiftModule: calling servo.StartHomingAsync(method=..., speed=...)`. Gọi _servo.TryFaultResetAsync → EnableAsync → SetHomingMethod/Speed/Offset → **StartHomingAsync**. |
+| 3 | **CiA402Servo.StartHomingAsync** | **Log:** `CiA402Servo[{DeviceId}]: StartHomingAsync method=..., speed=... -> writing to drive`. Ghi homing params (0x6098, 0x6099, 0x607C, 0x609A) → SetOperationMode(Homing) → SetControlword(0x000F) → SetControlword(0x001F) start homing. Qua **_canOpenDevice.WriteInt32Async / SetControlwordAsync** → **động cơ**. |
+
+**Kết luận:** Có gọi xuống động cơ. Nếu thấy log `CiA402Servo[...]: StartHomingAsync...` thì lệnh đã tới driver và được ghi xuống drive.
+
+---
+
+## 3. Điều kiện để liftCameraByHeight thực sự chạy
+
+- **LiftModuleService** phải ở trạng thái **Ready** khi gọi `LiftToPositionAsync`.  
+  Nếu đang Homing / Moving / Error / Uninitialized thì `Fire(StartMoving)` **không đổi state** → không vào Moving → **không gọi _servo.MoveToPositionAsync**.
+- **Log cần thấy khi chạy đúng:**
+  1. `LiftModule: StartMoving fired, target position ...`
+  2. `LiftModule: Moving state entered, calling servo.MoveToPositionAsync(position=...)`
+  3. `CiA402Servo[lift-motor]: MoveToPositionAsync position=... -> writing to drive`
+
+Nếu chỉ thấy (1) mà không thấy (2)(3) → state machine không ở Ready khi fire, hoặc _servo null.
+
+---
+
+## 4. Nguồn _servo trong LiftModuleService
+
+- Trong **StartAsync** (IHostedService): `_servo = _deviceProvider.GetDevice(_config.DeviceId)` với **DeviceId** từ config (vd. `Modules:LiftModule:DeviceId` = `"lift-motor"`).
+- Device phải là **ICiA402Servo** (thường là **CiA402Servo** PhenikaaX). Nếu không có device hoặc sai type → _servo = null → Moving state log "servo is null" và fire MovingFailed.

+
+## 10. Key Design Principles
+
+### Dependency Inversion
+- `LocalizationService` và `ScanMappingService` chỉ phụ thuộc vào `ICartographerService`
+- `CartographerService` là trung tâm quản lý dependencies: `CartographerSensorManager`, `MapStorageService`, `OccupancyGridProvider`
+
+### State Machine Pattern
+- Tất cả services sử dụng `Appccelerate.StateMachine` để quản lý lifecycle
+- States và triggers được định nghĩa rõ ràng trong các enum riêng biệt
+- State transitions được kiểm soát chặt chẽ để tránh race conditions
+
+### Single Responsibility
+- `CartographerService`: Quản lý Cartographer core và state machine chính
+- `LocalizationService`: Quản lý localization lifecycle
+- `ScanMappingService`: Quản lý scan mapping lifecycle
+- `MapStorageService`: Quản lý lưu/load maps
+- `OccupancyGridProvider`: Cung cấp occupancy grid từ maps
+- `CartographerSensorManager`: Quản lý sensor subscriptions và routing
+
+### Thread Safety
+- Sử dụng `Lock` (spin lock) cho các critical sections
+- Thread-safe event invocation với lock objects
+- State machines được khởi tạo lazy với `field` keyword (C# 14)
+
+### Resource Management
+- Tất cả services implement `IDisposable` để cleanup resources
+- State machines được stop trong `Dispose()`
+- Background threads được cancel và join trong `Dispose()`
+
+## 11. Notes
+
+- **CartographerService** là `IHostedService`, tự động start khi application start
+- **CartographerSensorManager** được inject vào `CartographerService` và expose qua property `SensorManager`
+- **OccupancyGridProvider** tự động chuyển sang `Ready` state khi `CartographerService` ở `Localizing` hoặc `ScanMapping` state
+- Tất cả services được đăng ký là `Singleton` trong DI container
+- State machines sử dụng lazy initialization với `field` keyword (C# 14 feature)

+# Database Design / Thiết kế Database
+
+## 📋 Overview / Tổng quan
+
+MapEditor sử dụng normalized relational schema để lưu trữ map data thay vì JSON blob.
+
+## 🎯 Design Philosophy / Triết lý Thiết kế
+
+### ❌ Anti-pattern (Not Used)
+
+```
+Maps table:
+  - id
+  - name
+  - vdma_lif_json TEXT  <-- Store entire JSON blob
+```
+
+**Problems với JSON blob approach**:
+- Cannot query specific elements
+- No foreign key constraints
+- Poor performance for complex queries
+- Cannot index nested data
+
+### ✅ Our Approach - Normalized Relational Schema
+
+**Benefits**:
+- Query any element directly
+- Foreign keys ensure data integrity
+- Efficient indexes
+- Easy to join với robot positions, orders, analytics

+
+## 🔑 Key Design Decisions
+
+**1. Dual ID System**:
+- `id` (UUID): Database primary key
+- `{entity}Id` (String): VDMA LIF identifier, business key
+
+**2. Position Decomposition**:
+- Store as separate columns: `positionX`, `positionY`, `positionTheta`
+- Enable spatial queries và indexing
+
+**3. Trajectory as JSON**:
+- Store NURBS trajectory as JSON string
+- Complex structure, rarely queried independently
+
+**4. Vehicle Type IDs as JSON Array**:
+- Store vehicleTypeIds as JSON array
+- Typically small arrays, loaded together with edge/node
+
+**5. Actions Hierarchy**:
+- Actions belong to InteractionNodes (not Stations directly)
+- Follows VDMA LIF structure exactly
+
+## 📈 Indexes for Performance
+
+**Critical Indexes**:
+- Maps: layoutId (unique)
+- Stations: mapId, stationId, stationType, (positionX, positionY)
+- Edges: mapId, edgeId, startStationId, endStationId
+- InteractionNodes: stationId, interactionNodeId

+
+## 📊 Graph Representation
+
+**Adjacency List Structure**:
+- Nodes Map: stationId → Station object
+- Edges Map: edgeId → Edge object
+- Adjacency List: stationId → List of Edge
+
+## 🎯 Heuristic Function
+
+**Euclidean Distance**:
+```
+h(station, goal) = sqrt((goal.x - station.x)² + (goal.y - station.y)²)
+```
+
+**Properties**:
+- Admissible: Never overestimates
+- Consistent: Satisfies triangle inequality
+- Guarantees: Optimal path với A*
+
+## ⚖️ Edge Weight Calculation
+
+**Weight = Travel Time**:
+```
+weight(edge) = edge.length / edge.maxSpeed
+```
+
+**Rationale**: Optimize for fastest path (considers both distance AND speed limits)
+
+## 🚗 Vehicle Type Filtering
+
+**Filter Logic**:
+- Edge có vehicleTypeIds empty/null → Allow all vehicles
+- Edge có vehicleTypeIds → Check if contains requestedType
+- If match → Include in graph
+- If no match → Exclude from graph
+
+## ✅ Path Validation
+
+**Validation Steps**:
+1. Connectivity: Path exists?
+2. Edge Sequence: Edges connect properly?
+3. Speed Limits: Robot capabilities compatible?
+4. Orientation: Robot can achieve required orientations?
+
+**Return Path Object**:
+- edgeIds: string[]
+- stationIds: string[]
+- totalDistance: float
+- estimatedTime: float
+- validationStatus: Valid | Warning | Invalid

+# MapEditor Documentation / Tài liệu MapEditor
+
+## 📋 Overview / Tổng quan
+
+**MapEditor** là shared library cung cấp công cụ web-based để tạo, chỉnh sửa và quản lý bản đồ nhà máy theo chuẩn VDMA LIF (Layout Interchange Format). Module này được sử dụng bởi **FleetManager** để định nghĩa không gian hoạt động của robot AMR.
+
+## 🎯 Problem & Solution / Vấn đề & Giải pháp
+
+### 🔴 Challenges / Thách thức
+
+**Trong môi trường nhà máy thực tế**:
+- Bản đồ nhà máy phức tạp với hàng trăm điểm (stations, nodes, edges)
+- Cần import/export data từ nhiều nguồn khác nhau (CAD tools, other fleet systems)
+- Operators không phải programmers, cần giao diện trực quan
+- Phải tuân thủ chuẩn VDMA LIF để tích hợp với hệ thống khác
+- Database cần normalized schema để query hiệu quả (không lưu JSON blob)
+- PathFinding để validate routes và generate VDA 5050 orders
+- Multi-map support cho nhiều tầng, nhiều khu vực
+
+### ✅ MapEditor Solution / Giải pháp MapEditor
+
+**Visual Editor**: Blazor WASM + SVG canvas
+- Vẽ và chỉnh sửa map objects trực quan (drag, drop, resize)
+- Pan, zoom, layer management
+- Real-time validation với visual feedback
+
+**VDMA LIF Standard**: Import/export JSON format
+- Tuân thủ VDMA 40499-1 và 40499-2 specifications
+- Interoperability với CAD tools và other fleet systems
+- Complete map data: stations, edges, zones, vehicle types
+
+**Normalized Database**: PostgreSQL với relational schema
+- Separate tables cho Maps, Stations, InteractionNodes, Edges, Actions
+- Foreign key constraints đảm bảo data integrity
+- Efficient queries (find all charging stations, edges by speed limit)
+- No JSON blob storage (except for complex nested data như trajectory)
+
+**PathFinding Integration**: A* algorithm
+- Validate route existence trước khi dispatch missions
+- Calculate shortest/fastest paths
+- Support bidirectional và unidirectional edges
+- Consider vehicle type compatibility
+
+**VDA 5050 Integration**: Generate Order messages
+- Convert map data (stations, edges) thành VDA 5050 nodes và edges
+- Include actions từ stations vào order
+- Apply vehicle type filtering
+
+### 🎪 Use Cases / Trường hợp Sử dụng
+
+**Initial Setup**:
+- Import VDMA LIF JSON từ AutoCAD hoặc design tool
+- Visual editing để adjust positions, thêm bớt elements
+- Define stations (pickup, dropoff, charging, parking)
+- Configure edges (paths, speed limits, directions)
+- Define zones (restricted areas, slow-speed zones)
+- Set up vehicle types (dimensions, envelopes)
+
+**Operations** (FleetManager):
+- Query database để tạo VDA 5050 Orders cho robots
+- PathFinding service validate routes trước khi dispatch
+- Operators view map trên dashboard với real-time robot positions
+- Export VDMA LIF để backup hoặc share với other systems
+
+**Maintenance**:
+- Update map khi factory layout thay đổi
+- Add/remove stations khi production changes
+- Adjust edge configurations (speed limits, orientations)
+- Manage multiple map versions (version control)

+# MapManager Database Design - Discussion Summary
+
+**Project:** RobotNet10.MapManager  
+**Date:** 2024-11-26  
+**Participants:** AI Assistant & DangNV  
+**Topic:** Database design for VDMA LIF 1.0.0 compliant map management system  
+**Final Version:** 2.0 (GUID-based naming)
+
+---
+
+## 📋 Overview
+
+This document summarizes the complete discussion and design decisions for the RobotNet10.MapManager database schema, which manages AGV/AMR maps according to VDMA LIF (Layout Interchange Format) 1.0.0 standard.
+
+**FINAL IMPLEMENTATION:** GUID 8-character based automatic naming system (optimized for Import/Export scenarios)
+
+---
+
+## 🎯 Project Goals
+
+1. **VDMA LIF Compliance**: 100% adherence to lif-schema.json specification
+2. **Multi-Level Support**: Handle buildings with multiple floors
+3. **Version Control**: Track layout changes over time
+4. **VehicleType Customization**: Per-vehicle properties for nodes and edges
+5. **Scalability**: Support up to 100k+ nodes and edges per level
+6. **Import/Export Ready**: Seamless VDMA LIF JSON import/export without conflicts
+
+---
+
+## 📚 Reference Documents
+
+- **VDMA LIF Schema**: `lif-schema.json` (provided by user)
+- **VDMA LIF Specification**: `FuI_Guideline_LIF_GB_final.pdf`
+- **Target Framework**: .NET 10.0
+- **ORM**: Entity Framework Core 9.0.0
+- **Database**: SQLite (design-time), SQL Server (production)
+
+---
+
+## 🔍 Key Discussion Points & Evolution
+
+### 1. Layout Hierarchy Structure
+
+**Decision: Option B - Hierarchy** ✅
+
+```
+Layout (Building/Facility)
+  └── LayoutVersion (Version History)
+      └── LayoutLevel (Floor/Level)
+          ├── Nodes
+          ├── Edges
+          └── Stations
+```
+
+**Rationale:**
+- Clear separation: Layout represents the facility, not a specific version
+- Multiple versions per layout for history tracking
+- Multiple levels per version for multi-floor buildings
+- VDMA LIF export: layoutId is shared across all levels within a version
+
+---
+
+### 2. VehicleType Architecture
+
+**Decision:** Separate `VehicleTypes` table as master data ✅
+
+**Structure:**
+```
+VehicleTypes (Master data)
+  ├── Used in: NodeVehicleProperties (junction table)
+  └── Used in: EdgeVehicleProperties (junction table)
+```
+
+**Key Points:**
+- VehicleType = Robot type (e.g., AMR-T800, AMR-F100)
+- One map can support multiple VehicleTypes
+- Properties are vehicle-specific:
+  - `vehicleTypeNodeProperties`: theta, actions (JSON)
+  - `vehicleTypeEdgeProperties`: orientation, speed limits, trajectory, etc.
+- No physical specs (width, length) - focus on schema-defined properties only
+
+---
+
+### 3. Zones vs Stations
+
+**Initial:** Zones concept was discussed  
+**Final Decision:** Use **Stations** per VDMA LIF schema ✅
+
+**Structure:**
+```
+Stations
+  └── StationInteractionNodes (Many-to-Many with Nodes)
+```
+
+**Rationale:**
+- VDMA LIF schema defines "stations" not "zones"
+- Stations have interactionNodeIds array
+- Represents loading/unloading points
+
+---
+
+### 4. Actions Storage
+
+**Decision:** Store as JSON within vehicleType properties ✅
+
+**Not separate tables** because:
+- Actions structure varies by action type
+- VDMA LIF defines actions as array within properties
+- Flexibility for different action parameters
+- Export/Import simplicity
+
+**Format:**
+```json
+{
+  "actions": [
+    {
+      "actionType": "pick",
+      "actionParameters": [...]
+    }
+  ]
+}
+```
+
+---
+
+### 5. Layout Flags & Versioning
+
+**Layouts:**
+- ~~`IsArchived`~~ ❌ Removed by user request
+- `IsActive` ✅ Added - Indicates if layout is currently active
+
+**LayoutVersions:**
+- `IsActive` ✅ - Only ONE active version per layout
+- When active → READ-ONLY (cannot edit)
+
+**LayoutLevels:**
+- `LevelOrder` ✅ Kept - For flexible UI sorting (not tied to layoutLevelId)
+
+---
+
+### 6. **Editor Settings - Major Design Evolution** ⭐
+
+This went through significant iteration:
+
+#### **Phase 1: Counter + Template Approach** (Initial Design)
+
+**Proposed Fields:**
+```
+LayoutLevelEditorSettings:
+- EdgeCount (long)
+- EdgeNameTemplate (string) e.g., "Edge_{0:D4}"
+- NodeCount (long)
+- NodeNameTemplate (string) e.g., "Node_{0:D4}"
+- EdgeMinLengthCreate (double)
+- EdgeNameAutoGenerate (bool)
+- NodeNameAutoGenerate (bool)
+- ImageWidth, ImageHeight (double?)
+```
+
+**Pros:**
+- ✅ Human-readable: Node_0001, Node_0002
+- ✅ Sortable chronologically
+- ✅ Template flexibility
+
+**Cons:**
+- ❌ **Import Problem**: When importing VDMA LIF with existing nodes, counter conflicts occur
+- ❌ Need atomic increment (complexity)
+- ❌ 4 extra fields for counter state
+- ❌ Template validation required
+
+---
+
+#### **Phase 2: GUID-based Approach** (Final) ✅✅✅
+
+**User Requirements:**
+1. Large project expected (10k+ items per level)
+2. Import/Export is critical - counter causes conflicts
+3. Human-readability NOT important
+4. Sortability NOT needed
+5. Reference by name: nice to have but not critical
+
+**Analysis Performed:**
+- **GUID 4 chars:** ❌ 7% collision @ 100 items (too risky)
+- **GUID 6 chars:** ⚠️ 3% collision @ 10k items (risky)
+- **GUID 8 chars:** ✅ 0.0012% collision @ 10k items (safe with retry)
+
+**Final Decision: GUID 8 Characters** ⭐
+
+**Simplified Fields:**
+```
+LayoutLevelEditorSettings:
+- EdgeNameAutoGenerate (bool)
+- NodeNameAutoGenerate (bool)
+- EdgeMinLengthCreate (double) - Meters
+- OriginX (double) - Coordinate origin X in meters
+- OriginY (double) - Coordinate origin Y in meters
+- Resolution (double) - Meters per pixel (default: 0.05)
+- BoundsMinX, BoundsMaxX (double?) - Coordinate bounds in meters
+- BoundsMinY, BoundsMaxY (double?) - Coordinate bounds in meters
+- ImageWidth (double?) - Pixels
+- ImageHeight (double?) - Pixels
+- CreatedDate, ModifiedDate (DateTime)
+```
+
+**14 fields total** (3 required coordinate fields + 4 optional bounds)
+
+**Name Format:**
+```
+Node_a7f2e3b1 (8-char GUID)
+Edge_3d8f9a2c (8-char GUID)
+```
+
+**Benefits:**
+- ✅ **Import-friendly**: No counter conflicts
+- ✅ **Concurrent-safe**: Parallel generation, no database locks
+- ✅ **Simpler**: 4 fewer fields, no template validation
+- ✅ **Scalable**: Safe up to 100k+ items with retry logic
+- ✅ **Fast**: No atomic increment overhead
+
+**Collision Safety:**
+```
+10,000 items: 0.0012% collision (1 in 83,000 cases)
+50,000 items: 0.03% collision (1 in 3,000 cases)
+100,000 items: 0.12% collision (1 in 800 cases)
+
+With 2 retries: Practically zero collision
+```
+
+**Service Implementation:**
+- Max 5 retries
+- Logging for collision monitoring
+- Exception if all retries fail (extremely unlikely)
+

+## 🔄 Import/Export Logic
+
+### **Export (Database → VDMA LIF JSON)**
+
+```
+Input: LayoutId + LayoutVersion
+Output: Single JSON file with all layoutLevelIds
+
+Structure:
+{
+  "metaInformation": {...},
+  "layouts": [
+    {
+      "layoutId": "warehouse_main",
+      "layoutVersion": "1.0",
+      "layoutLevelId": "floor_1",
+      "nodes": [...],
+      "edges": [...],
+      "stations": [...]
+    },
+    {
+      "layoutId": "warehouse_main",
+      "layoutVersion": "1.0",
+      "layoutLevelId": "floor_2",
+      ...
+    }
+  ]
+}
+```
+
+**Important:** ❌ Do NOT export `LayoutLevelEditorSettings` (internal only)
+
+### **Import (VDMA LIF JSON → Database)**
+
+```
+1. Create/Update Layout (by layoutId)
+2. Create/Update LayoutVersion (by layoutVersion)
+3. For each layoutLevelId:
+   a. Create/Update LayoutLevel

+## 🗺️ Coordinate System Design ⭐
+
+### **Overview**
+
+The MapManager uses a **dual coordinate system** approach to handle both physical world coordinates (for robot navigation) and image/screen coordinates (for UI rendering).
+
+### **Coordinate Systems**
+
+#### **1. World Coordinates (Physical Space)**
+- **Unit**: METERS (per VDMA LIF standard)
+- **Storage**: All Nodes, Edges, Stations store X, Y in meters
+- **Origin**: Defined by OriginX, OriginY in LayoutLevelEditorSettings
+- **Axis Convention**:
+  - X-axis: Right (positive)
+  - Y-axis: Up (positive) - Mathematical/Engineering convention
+- **Used for**: VDMA LIF data, robot navigation, path planning
+
+#### **2. Image Coordinates (Rendering Space)**
+- **Unit**: PIXELS
+- **Storage**: ImageWidth, ImageHeight in LayoutLevelEditorSettings
+- **Origin**: Top-left corner (standard image/screen convention)
+- **Axis Convention**:
+  - X-axis: Right (positive)
+  - Y-axis: Down (positive) - Image/Screen convention
+- **Used for**: Background image rendering, UI interactions
+
+### **Coordinate Transformation**
+
+**World → Image Pixel:**
+```csharp
+double imageX = (worldX - settings.OriginX) / settings.Resolution;
+double imageY = (settings.ImageHeight ?? 0) - ((worldY - settings.OriginY) / settings.Resolution);
+// Note: Y-axis is flipped (world Y-up vs image Y-down)
+```
+
+**Image Pixel → World:**
+```csharp
+double worldX = (imageX * settings.Resolution) + settings.OriginX;
+double worldY = ((settings.ImageHeight ?? 0) - imageY) * settings.Resolution + settings.OriginY;
+```
+
+### **LayoutLevelEditorSettings Coordinate Fields**
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| **OriginX** | double | 0.0 | World coordinate origin X in meters |
+| **OriginY** | double | 0.0 | World coordinate origin Y in meters |
+| **Resolution** | double | 0.05 | Meters per pixel (0.05 = 5cm per pixel) |
+| **BoundsMinX** | double? | null | Minimum X boundary in meters (optional) |
+| **BoundsMaxX** | double? | null | Maximum X boundary in meters (optional) |
+| **BoundsMinY** | double? | null | Minimum Y boundary in meters (optional) |
+| **BoundsMaxY** | double? | null | Maximum Y boundary in meters (optional) |
+| **ImageWidth** | double? | null | Background image width in pixels |
+| **ImageHeight** | double? | null | Background image height in pixels |
+
+### **Resolution Examples**
+
+| Resolution | Meaning | Use Case |
+|------------|---------|----------|
+| 0.01 | 1 pixel = 1 cm | High precision, small areas |
+| 0.05 | 1 pixel = 5 cm | **Default**, balanced |
+| 0.10 | 1 pixel = 10 cm | Large warehouses |
+| 0.50 | 1 pixel = 50 cm | Very large outdoor areas |
+
+### **Coordinate Bounds**
+
+Optional boundaries to constrain valid coordinates for a level:
+
+**Purpose:**
+- Prevent robots from being assigned invalid positions
+- Define operational area limits
+- Validate imported data
+
+**Example:**
+```
+Warehouse Level 1:
+- BoundsMinX: -10.0 meters (10m west of origin)
+- BoundsMaxX: 100.0 meters (100m east of origin)
+- BoundsMinY: -5.0 meters (5m south of origin)
+- BoundsMaxY: 50.0 meters (50m north of origin)
+- Total area: 110m × 55m = 6,050 square meters
+```
+
+**Validation:**
+```csharp
+bool IsWithinBounds(double x, double y, LayoutLevelEditorSettings settings)
+{
+    if (settings.BoundsMinX.HasValue && x < settings.BoundsMinX.Value) return false;
+    if (settings.BoundsMaxX.HasValue && x > settings.BoundsMaxX.Value) return false;
+    if (settings.BoundsMinY.HasValue && y < settings.BoundsMinY.Value) return false;
+    if (settings.BoundsMaxY.HasValue && y > settings.BoundsMaxY.Value) return false;
+    return true;
+}
+```
+
+### **Design Rationale**
+
+| Decision | Rationale |
+|----------|-----------|
+| **Meters in database** | VDMA LIF standard, robot navigation uses meters |
+| **Origin configurable** | Different maps have different reference points |
+| **Resolution per level** | Each floor may need different scale/precision |
+| **Y-axis flip in conversion** | World (Y-up) vs Image (Y-down) standards |
+| **Optional bounds** | Not always needed, flexibility |
+| **Part of EditorSettings** | Coordinate mapping is UI/editor concern, not VDMA LIF data |
+
+### **Import/Export Behavior**
+
+**Export (Database → VDMA LIF):**
+- ✅ Export Node.X, Node.Y directly (already in meters)
+- ✅ Export Station.X, Station.Y directly (already in meters)
+- ❌ Do NOT export OriginX, OriginY, Resolution (editor-specific)
+- ❌ Do NOT export Bounds (editor-specific)
+
+**Import (VDMA LIF → Database):**
+- ✅ Import coordinates directly to Node.X, Node.Y (meters)
+- ✅ Use default Origin (0, 0) and Resolution (0.05)
+- ✅ User can adjust Origin/Resolution after import for UI alignment
+
+### **Common Scenarios**
+
+#### **Scenario 1: New Map from Scratch**
+```
+1. Create LayoutLevel
+2. EditorSettings auto-created with defaults:
+   - OriginX = 0.0, OriginY = 0.0
+   - Resolution = 0.05 (5cm/pixel)
+3. User places nodes → stored in meters from (0,0)
+```
+
+#### **Scenario 2: Import Existing VDMA LIF**
+```
+1. Import nodes with world coordinates (meters)
+2. EditorSettings created with defaults
+3. User uploads background image
+4. User adjusts OriginX, OriginY to align image with nodes
+5. User adjusts Resolution if scale doesn't match
+```
+
+#### **Scenario 3: Large Warehouse**
+```
+1. Import facility map (1000m × 500m)
+2. Background image: 2000px × 1000px
+3. Calculate Resolution: 1000m / 2000px = 0.5 m/pixel
+4. Set OriginX = 0, OriginY = 0 (bottom-left corner)
+5. Set Bounds: MinX=0, MaxX=1000, MinY=0, MaxY=500
+```

+## 🎓 Key Learnings
+
+### **1. Import/Export First Design**
+- Original counter approach didn't account for import scenarios
+- GUID approach solves this elegantly
+- Design for data interchange, not just internal use
+
+### **2. Simplicity Wins**
+- Removed 4 fields (templates + counters)
+- Simpler is better when trade-offs are acceptable
+- User confirmed human-readability not critical
+
+### **3. Scale Appropriately**
+- 8-character GUID is sweet spot for this use case
+- Not too short (high collision), not too long (unnecessary)
+- Consider actual requirements, not theoretical extremes
+
+### **4. VDMA LIF Extensions**
+- Clearly separate VDMA LIF data from UI extensions
+- Document which fields are NOT exported
+- Maintain 100% schema compliance where it matters
+

+
+### **14. Trajectory Degree Change Logic**
+**Khi TĂNG Degree (thêm control points):**
+- **Degree 1 → Degree 2:** Thêm 1 point tại giữa curve (t = 0.5)
+- **Degree 2 → Degree 3:** Thêm 1 point tại t = 0.33 hoặc t = 0.67
+- Chèn điểm mới ở giữa 2 điểm có khoảng cách lớn nhất để giữ biên dạng ít thay đổi
+
+**Khi GIẢM Degree (xóa control points):**
+- **Degree 3 → Degree 2:** Giữ P0 và P_last, tính P_middle = weighted average của các control points cũ
+- **Degree 2 → Degree 1:** Chỉ giữ P0 và P_last, curve thành đường thẳng
+- Giảm từ n points xuống n-1 points bằng cách tính trung bình các cặp điểm liền kề
+
+### **15. Actions Form Builder**
+| Feature | Behavior |
+|---------|----------|

+[Merge][Split] │ 
+VehicleType: [AMR-T800 ▼] │ 
+[Undo][Redo] [Save] [Delete] [Check] [Exit]
+```
+
+**Note:** Display Options và Grid Spacing đã được chuyển vào Settings Tab (không còn trên Toolbar).

+
+## 🎯 Implementation Phases
+
+### **Phase 1: Foundation (Core Structure)** ✅ COMPLETE
+**Status:** Hoàn thành trong cuộc hội thoại ban đầu
+
+**Deliverables:**
+- `LayoutEditorComponent.razor` - Main container với left canvas, right panel
+- `EditorToolbar.razor` - Full toolbar với tất cả buttons
+- `LayoutEditorState.cs` - Centralized state management
+- Host page: `RobotApp.Client/Pages/LayoutEditor.razor` với route `/layout-editor/{LevelId:guid}`
+- Navigation từ LayoutManager page
+
+**Key Features:**
+- State management với data loading (Level, Nodes, Edges, Stations, VehicleTypes)
+- Selection management (single/multi-select)
+- Viewport control structure (`ViewportState` class)
+- Coordinate transforms (SVG ↔ World)
+- Undo/Redo stack (Command pattern với `EditorCommand` abstract class)
+- Editor modes enum (`Select`, `Scanner`, `CreateEdge1Way`, `CreateEdge2Way`, `Pan`, `Move`, `Copy`)
+
+**State Management Structure:**
+- `LayoutEditorState` - Centralized state với:
+  - Data: `Level`, `Nodes`, `Edges`, `Stations`, `VehicleTypes`
+  - Selection: `SelectedNodeIds`, `SelectedEdgeIds`
+  - Viewport: `ViewportState` (ViewBoxX, ViewBoxY, ViewBoxWidth, ViewBoxHeight, ZoomLevel)
+  - Display options: `ShowEdgeNames`, `ShowNodeNames`, `ShowGrid`, `ShowBackgroundImage`, `GridSpacing`
+  - Undo/Redo: `UndoStack`, `RedoStack`
+  - Editor mode: `CurrentMode`
+  - Methods: `InitializeAsync()`, `Pan()`, `Zoom()`, `FitToScreen()`, `SelectNodes()`, `SelectEdges()`, etc.
+
+**Command Pattern:**
+- `EditorCommand` abstract class với `Execute()` và `Undo()` methods
+- `MoveNodesCommand` - Example command cho move operations
+- Commands được push vào `UndoStack` khi execute
+
+---
+
+### **Phase 2: SVG Canvas (Basic)** ✅ COMPLETE
+**Status:** Hoàn thành trong cuộc hội thoại ban đầu
+
+**Deliverables:**
+- `SvgEditorCanvas.razor` - SVG rendering component
+- `MousePositionDisplay.razor` - World coordinates display (góc trên trái)
+- `svgEditor.js` - JavaScript interop module
+
+**Key Features:**
+- Background image rendering (Y-axis flip để match world coordinates)
+- Grid rendering (togglable, configurable spacing)
+- Nodes rendering (circles, green color for nodes with stations)
+- Edges rendering (lines with direction arrows at EndNode)
+- Edge/Node names (togglable, scale with zoom level)
+- Box select rectangle visualization (Scanner mode)
+- Create edge preview line (dashed/gray line from start node to mouse)
+- Mouse position tracking (world coordinates in meters, displayed top-left)
+
+**Coordinate System:**
+- **World Coordinates:** Bottom-left origin (0,0), Y increases upward (meters)
+- **SVG Coordinates:** Top-left origin (0,0), Y increases downward (pixels)
+- **Transform:** `svgY = physicalHeight - worldY` (flip Y axis)
+
+**JavaScript Interop (`svgEditor.js`):**
+- Mouse events: `mousemove`, `mousedown`, `mouseup`, `wheel`
+- Keyboard shortcuts: `keydown` (Ctrl+Z/Y/S, Delete, Escape)
+- Coordinate conversion: `screenToSvg()`, `screenToSvgArray()` (exported for Blazor)

+
+**Rendering Layers (implemented):**
+1. Background Image (if available)
+2. Grid (if `ShowGrid` = true)
+3. Edges (with arrows and names if enabled)
+4. Nodes (circles with names if enabled)
+5. Selection highlights (rings around selected nodes)
+6. Box select rectangle (when in Scanner mode)
+7. Create edge preview line (when creating edge)
+
+**Event Handling:**
+- `OnMouseMove` - Updates mouse position, handles box select, pan, create edge preview
+- `OnMouseDown` - Handles selection, starts pan, starts create edge
+- `OnMouseUp` - Ends pan, completes box select, completes create edge
+- `OnWheel` - Handles zoom (with cursor position preservation)
+
+---
+
+### **Phase 3: Viewport Controls** ⏳ IN PROGRESS
+**Status:** Đã implement cơ bản, đang polish và fix bugs
+
+#### **3.1. Pan (Middle Mouse Drag)** ✅ FIXED
+**Vấn đề ban đầu:**
+- Pan bị giật và không di chuyển đúng theo chuột
+- Delta bị cộng dồn khi di chuyển chuột
+
+**Nguyên nhân:**
+- Tính delta từ điểm bắt đầu pan mỗi lần mouse move
+- Khi ViewBox thay đổi sau mỗi lần pan, việc convert `panStartScreen` sang SVG cho giá trị khác
+- Gây ra việc cộng dồn delta
+
+**Giải pháp:**
+- Thay đổi từ tính delta từ điểm bắt đầu sang **incremental delta**
+- Lưu `panLastScreen` (vị trí screen của lần move trước)
+- Mỗi lần mouse move:
+  1. Convert `panLastScreen` và `currentScreen` sang SVG (dùng ViewBox hiện tại)
+  2. Tính delta = `lastSvg - currentSvg`
+  3. Pan ViewBox theo delta
+  4. Update `panLastScreen = currentScreen`
+
+**Code Changes:**
+```csharp
+// Thêm panLastScreen để track vị trí trước đó
+private (double X, double Y)? panLastScreen;
+
+// Trong OnMouseMove:
+if (isPanning && panLastScreen.HasValue)
+{
+    // Tính incremental delta từ lần move trước
+    _ = PanIncrementalAsync(panLastScreen.Value.X, panLastScreen.Value.Y, screenX, screenY);
+    panLastScreen = (screenX, screenY);
+}
+
+// Trong OnMouseDown (button == 1):
+panStartScreen = (screenX, screenY);
+panLastScreen = (screenX, screenY); // Initialize
+```
+
+**JavaScript Changes:**
+- Thêm `screenToSvgArray()` function để export cho Blazor
+- `OnMouseMove` và `OnMouseDown` nhận thêm `screenX, screenY` parameters
+
+#### **3.2. Zoom (Mouse Wheel)** ✅ FIXED
+**Vấn đề ban đầu:**
+- Zoom không giữ tọa độ mouse không đổi
+- Zoom không chính xác tại vị trí cursor
+
+**Giải pháp:**
+- Tính tỷ lệ vị trí cursor trong viewBox hiện tại
+- Giữ điểm cursor không đổi trong world coordinates khi zoom
+- Logic:
+  ```csharp
+  // Tính ratio của cursor trong viewBox
+  var ratioX = (svgCenterX - ViewBoxX) / ViewBoxWidth;
+  var ratioY = (svgCenterY - ViewBoxY) / ViewBoxHeight;
+  
+  // New dimensions
+  var newWidth = ViewBoxWidth / factor;
+  var newHeight = ViewBoxHeight / factor;
+  
+  // Adjust ViewBox để giữ cursor tại cùng vị trí world
+  ViewBoxX = svgCenterX - ratioX * newWidth;
+  ViewBoxY = svgCenterY - ratioY * newHeight;
+  ```
+
+#### **3.3. Grid Rendering** ✅ FIXED
+**Thay đổi:**
+- `stroke="#999"` (đậm hơn, từ #ccc)
+- `stroke-width="0.04"` (đậm gấp đôi, từ 0.02)
+- `opacity="0.7"` (rõ hơn, từ 0.5)
+- Thêm `stroke-dasharray="0.1,0.1"` (nét đứt)
+
+---

+**Đã implement:**
+- CreateEdge 1-Way mode với API call (`CreateEdgeAsync`)
+- CreateEdge 2-Way mode với API call (tạo 2 edges ngược chiều)
+- Edge preview while creating (preview line + preview nodes)
+- Smart node detection (tích hợp API - tự động tìm node trong `NodeProximityRadius` hoặc tạo mới)
+- Preview node hiển thị tại vị trí click đầu tiên và vị trí mouse
+- Escape key để cancel CreateEdge operation
+
+**API Integration:**
+- `POST /api/edges` - Create edge với smart node detection
+- Backend tự động tìm hoặc tạo nodes tại tọa độ start/end
+- Nếu điểm nằm trong `NodeProximityRadius` của node hiện có → kết nối với node đó
+- Nếu không → tạo node mới tại tọa độ đó
+
+**Visual Features:**
+- Preview line: dashed line từ start node đến mouse position
+- Preview nodes: semi-transparent circles tại start và end positions
+- 2-way edges: hiển thị thành 2 đường song song với offset
+
+---
+
+### **Phase 6: Edit Operations** ⏳ PARTIAL
+**Status:** Đã implement một phần
+
+#### **6.1. Move Nodes** ✅ COMPLETE
+- **Trigger:** Ctrl + Drag (hoặc Move mode với Ctrl+M)
+- **Behavior:** Di chuyển node theo chuột, khi thả Ctrl thì giữ nguyên vị trí hiện tại
+- **Undo/Redo:** Hỗ trợ qua `MoveNodesCommand`
+- **Change Tracking:** Đánh dấu nodes đã modified để Save sau
+
+#### **6.2. Copy Nodes/Edges** ✅ COMPLETE

+  - Click và drag để định offset
+  - Preview nodes và edges tại vị trí mới
+  - Thả chuột để hoàn thành copy
+  - Escape để cancel
+- **API:** `POST /api/layout-data/copy-nodes` - Backend xử lý toàn bộ logic
+- **Logic:**
+  - Tạo tất cả nodes mới với offset trước (validate coordinates, copy vehicle properties)
+  - Sau đó tạo tất cả edges mới (sử dụng node ID mapping)
+  - Xử lý 2-way edges: copy cả forward và reverse edge
+  - Không copy stations
+- **Selection:** Tự động select các nodes/edges mới sau khi copy
+
+#### **6.3. Delete Selected** ✅ COMPLETE
+- **Trigger:** Delete button hoặc Delete key
+- **API:** `DELETE /api/edges/{id}` hoặc batch delete
+- **Behavior:** Xóa edges, backend tự động xóa orphaned nodes
+- **Confirmation:** Dialog xác nhận trước khi xóa
+
+#### **6.4. Merge Nodes** ✅ COMPLETE
+- **Trigger:** Toolbar button (khi có 2+ nodes selected)
+- **API:** `POST /api/layout-data/merge-nodes`
+- **Behavior:**
+  - Gộp tất cả selected nodes thành 1 node tại vị trí center
+  - Redirect tất cả edges đến node mới
+  - Gộp vehicle properties từ tất cả nodes
+  - Nếu nhiều nodes có stations → dialog chọn node giữ station
+  - Distance check: nếu nodes ngoài `NodeProximityRadius` → confirmation dialog
+- **Selection:** Tự động select node mới sau khi merge
+
+#### **6.5. Split Node** ✅ COMPLETE
+- **Trigger:** Toolbar button (khi có 1 node selected với 2+ edges)
+- **API:** `POST /api/layout-data/split-node`
+- **Behavior:**
+  - Split 1 node thành N nodes (N = số edges connected)
+  - Mỗi edge được redirect đến node mới tương ứng
+  - Copy vehicle properties đến tất cả nodes mới
+  - Nếu node có station → dialog chọn node nhận station
+  - Validation: node phải có ít nhất 2 edges mới được split
+- **Selection:** Tự động select tất cả nodes mới sau khi split
+
+#### **6.6. Alignment Functions** ❌ NOT STARTED
+- **Status:** Buttons đã có, chưa implement logic
+
+---
+
+### **Phase 7: Right Panel - Properties** ⏳ PARTIAL
+**Status:** UI đã có, cần tích hợp API
+
+#### **7.1. Settings Tab** ✅ FIXED & ENHANCED
+**Thay đổi trong cuộc hội thoại này:**

+- Thêm `EditorSettings` property vào `UpdateLayoutLevelRequest`
+- Cập nhật `LayoutService.UpdateLevelAsync()` để xử lý editor settings
+- Settings được lưu vào database khi click Save
+
+**Code Structure:**
+```csharp
+// Local editable state
+private bool nodeNameAutoGenerate;
+private bool edgeNameAutoGenerate;
+private double edgeMinLengthCreate;
+private double nodeProximityRadius;
+
+// Initialize từ settings khi component load
+protected override void OnParametersSet()
+{
+    if (State.Level?.EditorSettings != null)
+    {
+        var settings = State.Level.EditorSettings;
+        nodeNameAutoGenerate = settings.NodeNameAutoGenerate;
+        // ... initialize other fields
+    }
+}
+
+// Save to API
+private async Task SaveEditorSettings()
+{
+    var request = new UpdateLayoutLevelRequest
+    {
+        EditorSettings = new EditorSettingsInfo
+        {
+            NodeNameAutoGenerate = nodeNameAutoGenerate,
+            // ... other fields
+        }
+    };
+    var updatedLevel = await ApiService.UpdateLevelAsync(State.Level.Id, request);

+}
+```
+
+**Đã có:**
+- Node properties editor (UI)
+- Edge properties editor (UI)
+- VehicleType dropdown
+- Vehicle properties editor (UI)
+- Station info display
+
+**Cần làm:**
+- Save properties to API

+- Drag control points
+- Add/Remove control points
+- Change degree (với logic giữ biên dạng ít thay đổi)
+
+---
+
+### **Phase 9: Actions Form Builder** ❌ NOT STARTED
+**Status:** Chưa thực hiện
+
+**Cần implement:**
+- Actions form dialog
+- ActionType dropdown (VehicleType defaults + custom text)
+- Parameters key-value editor
+- Validation
+
+---
+
+### **Phase 10: Undo/Redo & Save** ⏳ PARTIAL
+**Status:** Structure đã có, Save API đã implement
+
+**Đã có:**
+- Command pattern structure
+- Undo stack
+- Redo stack
+- Save button (UI)
+- Save API: `POST /api/layout-data/save` - Batch save với transaction
+- Change tracking: `_modifiedNodeIds`, `_modifiedEdgeIds`

+
+## 🏗️ Architecture Overview
+
+### **Component Hierarchy**
+```
+LayoutManager (click Edit) 
+    → Navigate to /layout-editor/{levelId}
+        → LayoutEditorComponent
+            ├── EditorToolbar (top)
+            ├── SVG Canvas (left) + MousePositionDisplay
+            └── Right Panel
+                ├── Properties Tab
+                │   ├── NodePropertiesEditor (single node)
+                │   └── EdgePropertiesEditor (single edge)
+                └── Settings Tab

+                    ├── Display Options
+                    ├── Auto-generation Settings
+                    ├── Layout Level Info
+                    └── Statistics
+```
+
+### **Data Flow**
+1. **Initialization:**
+   - User clicks "Edit" on LayoutManager
+   - Navigate to `/layout-editor/{levelId}`
+   - `LayoutEditorComponent` loads
+   - `LayoutEditorState.InitializeAsync()` fetches:
+     - Level info (with EditorSettings)
+     - Layout data (Nodes, Edges, Stations)
+     - VehicleTypes
+     - Background image (if available)
+   - Viewport initialized to fit image bounds
+
+2. **User Interactions:**
+   - Mouse events → JavaScript (`svgEditor.js`) → Blazor (`SvgEditorCanvas.razor`)
+   - State changes → `LayoutEditorState` → Notify components via `OnStateChanged` event
+   - UI updates → Blazor re-renders affected components
+
+3. **Save Operations:**
+   - User edits properties → Local state changes
+   - Click "Save Settings" → API call (`MapManagerApiService.UpdateLevelEditorSettingsAsync`)
+   - Backend updates database → Returns updated Level
+   - State updated → UI refreshed
+
+### **State Management Pattern**
+- **Centralized State:** `LayoutEditorState` (scoped service)
+- **Event-driven:** Components subscribe to `OnStateChanged` event
+- **Immutable Updates:** State methods return new state or update properties and notify
+- **Command Pattern:** Undo/Redo via `EditorCommand` abstract class
+
+### **Coordinate Transformation**
+- **World → SVG:** `WorldToSvg(worldX, worldY)` → `(worldX, physicalHeight - worldY)`
+- **SVG → World:** `SvgToWorld(svgX, svgY)` → `(svgX, physicalHeight - svgY)`
+- **Screen → SVG:** JavaScript `screenToSvgArray(screenX, screenY)` using `getScreenCTM()`
+
+### **API Integration**
+- **Service:** `MapManagerApiService` (injected)
+- **Endpoints Used:**
+  - `GET /api/layouts/{layoutId}/levels/{levelId}` - Get level info
+  - `GET /api/layouts/{layoutId}/levels/{levelId}/data` - Get layout data
+  - `PUT /api/layouts/{layoutId}/levels/{levelId}` - Update level (including editor settings)
+  - `GET /api/layouts/{layoutId}/levels/{levelId}/background-image` - Get background image
+  - `POST /api/edges` - Create edge (with smart node detection)
+  - `DELETE /api/edges/{id}` - Delete edge (single)
+  - `DELETE /api/edges/batch` - Delete edges (batch)
+  - `POST /api/layout-data/save` - Batch save nodes/edges (transactional)
+  - `POST /api/layout-data/copy-nodes` - Copy nodes/edges with offset
+  - `POST /api/layout-data/merge-nodes` - Merge multiple nodes into one
+  - `POST /api/layout-data/split-node` - Split one node into multiple nodes
+
+---
+
+## 🔧 Technical Details
+
+### **Coordinate System**
+- **World Coordinates:** Bottom-left origin (0,0), Y increases upward, units in meters
+- **SVG Coordinates:** Top-left origin (0,0), Y increases downward, units in pixels
+- **Transform:** `svgY = physicalHeight - worldY` (flip Y axis)
+
+### **Pan Logic (Fixed)**
+- Sử dụng incremental delta thay vì delta từ điểm bắt đầu
+- Lưu `panLastScreen` để track vị trí trước đó
+- Convert screen coordinates sang SVG mỗi lần để đảm bảo chính xác khi ViewBox thay đổi
+
+### **Zoom Logic (Fixed)**
+- Zoom tại vị trí cursor
+- Giữ tọa độ mouse không đổi trong world space
+- Tính ratio của cursor trong viewBox và adjust ViewBox position
+
+### **Grid Styling**
+- Stroke: `#999` (đậm)
+- Stroke width: `0.04` (đậm gấp đôi)
+- Opacity: `0.7` (rõ)
+- Stroke dasharray: `0.1,0.1` (nét đứt)
+
+### **Text Rendering (Node/Edge Names)**
+- **Font Size Formula:** `fontSizeSVG = baseFontSizeWorld / (Resolution * ZoomLevel)`
+  - `baseFontSizeWorld`: 0.24 meters
+  - `Resolution`: meters per pixel (from `EditorSettings.Resolution`)
+  - `ZoomLevel`: current zoom factor
+- **Result:** Text có cùng kích thước visual với mọi Resolution, zoom theo ZoomLevel
+- **Color:** Red (#f44336)
+- **Font:** Segoe UI, font-weight 500
+- **Letter Spacing:** -0.02em (characters gần nhau hơn)
+- **Position:**
+  - Node names: Below node center
+  - Edge names: Above edge center
+
+### **Settings Tab Structure**
+1. Grid Settings (editable)
+2. Display Options (session state)
+3. Auto-generation Settings (editable với Save button)
+4. Layout Level Info (read-only)
+5. Statistics (read-only)
+

+
+## 🐛 Bugs Fixed in This Session
+
+### **1. Pan Logic - Cộng Dồn Delta**
+**Problem:** Pan bị cộng dồn quãng đường di chuyển
+**Root Cause:** Tính delta từ điểm bắt đầu mỗi lần thay vì incremental
+**Solution:** Chuyển sang incremental delta từ lần move trước
+
+### **2. Zoom Logic - Tọa Độ Mouse Thay Đổi**
+**Problem:** Zoom không giữ tọa độ mouse không đổi
+**Solution:** Tính ratio và adjust ViewBox để giữ cursor tại cùng vị trí world
+
+### **3. Grid Styling**
+**Problem:** Grid quá nhạt và nét liền
+**Solution:** Đậm hơn, opacity cao hơn, thêm stroke-dasharray
+
+### **4. Settings Tab - Display Options**
+**Problem:** Display Options ở Toolbar thay vì Settings
+**Solution:** Chuyển về Settings Tab, xóa khỏi Toolbar
+
+### **5. Settings Tab - Auto-generation Settings Read-only**
+**Problem:** Auto-generation Settings chỉ hiển thị, không thể edit
+**Solution:** Làm editable với local state và Save button, tích hợp API
+
+### **6. Create Edge - Smart Node Detection**
+**Problem:** CreateEdge không hoạt động, chỉ tạo được trên nodes đã có
+**Solution:** 
+- Backend API tự động detect nodes trong `NodeProximityRadius` hoặc tạo mới
+- Frontend chỉ cần gửi world coordinates, backend xử lý logic
+
+### **7. 2-Way Edges Visualization**
+**Problem:** 2-way edges hiển thị thành 1 line với 2 arrowheads
+**Solution:** Tính toán offset để hiển thị thành 2 đường song song riêng biệt
+
+### **8. Text Font Size - Resolution Independence**
+**Problem:** Text size thay đổi khi Resolution thay đổi
+**Solution:** Công thức `fontSizeSVG = baseFontSizeWorld / (Resolution * ZoomLevel)` để text có cùng kích thước visual với mọi Resolution
+
+### **9. HasUnsavedChanges - Direct API Calls**
+**Problem:** `HasUnsavedChanges` được set sau các API calls trực tiếp (CreateEdge, DeleteEdge, etc.)
+**Solution:** Xóa `HasUnsavedChanges = true` sau các API calls trực tiếp vì đã lưu vào database rồi
+
+### **10. CopyNodesAsync - Refactor**
+**Problem:** Copy logic phức tạp ở frontend, dùng temp edges
+**Solution:** 
+- Refactor để backend xử lý toàn bộ logic
+- Tạo nodes trực tiếp vào database (validate coordinates, copy vehicle properties)
+- Tạo edges trực tiếp với node ID mapping
+- Xử lý 2-way edges tự động
+
+---

+### Design Patterns
+
+1. **Component Pattern:** Separation of Page vs Component
+   - `LayoutManager.razor` (Page): Routing, render mode, providers
+   - `LayoutManagerComponent.razor` (Component): Business logic, UI
+
+2. **State Management:** Centralized state with event notification
+   - `LayoutManagerState`: Single source of truth
+   - `OnStateChanged` event for reactive updates
+
+3. **API Service:** HTTP client wrapper
+   - `MapManagerApiService`: Encapsulates all API calls
+   - Typed DTOs for request/response
+
+4. **Repository Pattern:** Backend data access
+   - `ILayoutService`: Business logic interface
+   - EF Core for data persistence

+
+## State Management
+
+### LayoutManagerState.cs
+
+**Responsibilities:**
+- Hold current UI state (selected layout/version/level)
+- Load data from API
+- Cache preview data and images
+- Notify components of changes via events
+
+**Key Properties:**
+
+```csharp
+public class LayoutManagerState
+{
+    // Data
+    public List<LayoutDto> Layouts { get; private set; }
+    public LayoutDto? SelectedLayout { get; private set; }
+    public LayoutVersionDto? SelectedVersion { get; private set; }
+    public LayoutLevelDto? SelectedLevel { get; private set; }
+    
+    // Preview Data
+    public LayoutDataDto? PreviewData { get; private set; }
+    public byte[]? PreviewImage { get; private set; }
+    
+    // Loading States
+    public bool IsLoading { get; private set; }
+    public bool IsLoadingPreview { get; private set; }
+    
+    // Event for reactive updates
+    public event Action? OnStateChanged;
+}
+```
+
+**Key Methods:**
+
+```csharp
+// Load all layouts from API
+public async Task LoadLayoutsAsync(string? search = null)
+
+// Select a level and load its preview
+public async Task SelectLevelAsync(LayoutLevelDto level)
+
+// CRUD operations
+public async Task CreateLayoutAsync(CreateLayoutRequest request)
+public async Task CreateVersionAsync(Guid layoutId, CreateLayoutVersionRequest request)
+public async Task CreateLevelAsync(Guid versionId, CreateLayoutLevelRequest request)
+public async Task DeleteLayoutAsync(Guid layoutId)
+public async Task DeleteVersionAsync(Guid versionId)
+public async Task DeleteLevelAsync(Guid levelId)
+```
+
+**Usage Pattern:**
+
+```csharp
+@inject LayoutManagerState State
+@implements IDisposable
+
+protected override async Task OnInitializedAsync()
+{
+    // Subscribe to state changes
+    State.OnStateChanged += StateHasChanged;
+    
+    // Load initial data
+    await State.LoadLayoutsAsync();
+}
+
+public void Dispose()
+{
+    // Unsubscribe to prevent memory leaks
+    State.OnStateChanged -= StateHasChanged;
+}
+```
+
+---
+
+## API Integration
+
+### MapManagerApiService.cs
+
+**Base Configuration:**
+
+```csharp
+// Program.cs
+builder.Services.AddHttpClient<MapManagerApiService>(client =>
+{
+    var baseUrl = builder.Configuration["MapManagerApi:BaseUrl"] ?? "https://localhost:5001";
+    client.BaseAddress = new Uri(baseUrl);
+});
+
+builder.Services.AddScoped<LayoutManagerState>();
+```
+
+**API Methods:**
+
+```csharp
+public class MapManagerApiService
+{
+    // Layouts
+    Task<List<LayoutDto>> SearchLayoutsAsync(string? search = null)
+    Task<LayoutDto> CreateLayoutAsync(CreateLayoutRequest request)
+    Task<LayoutDto> UpdateLayoutAsync(Guid layoutId, UpdateLayoutRequest request)
+    Task DeleteLayoutAsync(Guid layoutId)
+    Task<LayoutDto> ActivateLayoutAsync(Guid layoutId)
+    Task<LayoutDto> DeactivateLayoutAsync(Guid layoutId)
+    
+    // Versions
+    Task<LayoutVersionDto> CreateVersionAsync(Guid layoutId, CreateLayoutVersionRequest request)
+    Task<List<LayoutVersionDto>> GetVersionsAsync(Guid layoutId)
+    Task DeleteVersionAsync(Guid versionId)
+    
+    // Levels
+    Task<LayoutLevelDto> CreateLevelAsync(Guid versionId, CreateLayoutLevelRequest request)
+    Task<LayoutLevelDto> CreateLevelWithImageAsync(
+        Guid versionId, string layoutLevelId, int levelOrder,
+        double resolution, double originX, double originY,
+        Stream imageStream, string fileName)
+    Task<LayoutLevelDto> UpdateLevelAsync(Guid levelId, UpdateLayoutLevelRequest request)
+    Task DeleteLevelAsync(Guid levelId)
+    
+    // Layout Data
+    Task<LayoutDataDto> GetLayoutDataAsync(Guid layoutLevelId)
+    
+    // Images
+    Task<byte[]?> GetLayoutImageAsync(Guid layoutLevelId)
+    Task UploadLayoutImageAsync(Guid layoutLevelId, Stream imageStream, string fileName)
+    Task DeleteLayoutImageAsync(Guid layoutLevelId)
+}
+```
+
+### HTTP Request Flow
+
+**Example: Create Level with Image**
+
+```
+1. Frontend: User fills CreateLevelDialog
+   ↓
+2. Frontend: Call CreateLevelWithImageAsync()
+   ↓
+3. HTTP: POST /api/layouts/versions/{versionId}/levels/with-image
+   Content-Type: multipart/form-data
+   Body:
+     - layoutLevelId: "floor_1"
+     - levelOrder: 0
+     - resolution: 0.05
+     - originX: 0
+     - originY: 0
+     - file: [PNG binary]
+   ↓
+4. Backend: LayoutManagerController.CreateLevelWithImage()
+   a. Extract image dimensions (ImageSharp)
+   b. Create LayoutLevel entity
+   c. Create LayoutLevelEditorSettings entity
+   d. Save to database
+   e. Upload image to storage
+   f. (Rollback if image upload fails)
+   ↓
+5. Backend: Return 201 Created with LayoutLevelDto
+   ↓
+6. Frontend: Update state, refresh UI
+   ↓
+7. Frontend: Show success notification
+```

+
+## Implementation Details
+
+### 1. Tree View Implementation
+
+**Challenge:** MudBlazor `MudTreeView` has complex data binding.
+
+**Solution:** Custom tree rendering with nested MudPaper + MudStack
+
+```razor
+@foreach (var layout in State.Layouts)
+{
+    <MudPaper>
+        <MudStack Row="true">
+            <MudIconButton Icon="..." OnClick="() => ToggleLayout(layout.Id)" />
+            <MudIcon Icon="@Icons.Material.Filled.Map" />
+            <MudText>@layout.LayoutName</MudText>
+            <MudMenu>...</MudMenu>
+        </MudStack>
+    </MudPaper>
+    
+    @if (expandedLayouts.Contains(layout.Id))
+    {
+        <MudStack Class="ml-6">
+            @foreach (var version in layout.Versions)
+            {
+                <!-- Nested version rendering -->
+            }
+        </MudStack>
+    }
+}
+```
+
+**State:**
+```csharp
+private HashSet<Guid> expandedLayouts = new();
+private HashSet<Guid> expandedVersions = new();
+
+private void ToggleLayout(Guid layoutId)
+{
+    if (expandedLayouts.Contains(layoutId))
+        expandedLayouts.Remove(layoutId);
+    else
+        expandedLayouts.Add(layoutId);
+}
+```
+
+---
+
+### 2. SVG Preview Canvas
+
+**Challenge:** Responsive SVG that fits container without overflow.
+
+**Solution:** Dynamic viewBox calculation
+
+```razor
+<svg width="100%" height="100%" viewBox="@ViewBoxString" ...>
+    <image href="@GetImageDataUrl()" 
+           x="0" y="0"
+           width="@GetImageWidth()" 
+           height="@GetImageHeight()" />
+    
+    <!-- Nodes, Edges, Stations -->
+</svg>
+```
+
+**ViewBox Logic:**
+```csharp
+private string ViewBoxString
+{
+    get
+    {
+        // If image exists, use physical size (meters)
+        if (EditorSettings?.ImageWidth.HasValue == true)
+        {
+            var width = EditorSettings.ImageWidth.Value * EditorSettings.Resolution;
+            var height = EditorSettings.ImageHeight.Value * EditorSettings.Resolution;
+            return $"0 0 {width:F2} {height:F2}";
+        }
+        
+        // Otherwise, calculate from nodes
+        if (LayoutData?.Nodes.Count > 0)
+        {
+            var minX = LayoutData.Nodes.Min(n => n.X);
+            var maxX = LayoutData.Nodes.Max(n => n.X);
+            var minY = LayoutData.Nodes.Min(n => n.Y);
+            var maxY = LayoutData.Nodes.Max(n => n.Y);
+            var padding = Math.Max((maxX - minX), (maxY - minY)) * 0.1;
+            return $"{minX - padding:F2} {minY - padding:F2} ...";
+        }
+        
+        // Default
+        return "0 0 100 50";
+    }
+}
+```
+
+**Key Points:**
+- `width="100%" height="100%"` → SVG scales to container
+- `viewBox` defines coordinate system (meters, not pixels)
+- Image dimensions in meters: `PixelSize × Resolution`
+- `preserveAspectRatio="none"` → Image stretches to fill viewBox
+
+---
+
+### 3. Image Upload with Dimension Extraction
+
+**Frontend (Client-Side):**
+
+```csharp
+private async Task OnImageSelected(InputFileChangeEventArgs e)
+{
+    var file = e.File;
+    
+    // Read file as byte array
+    using var stream = file.OpenReadStream(maxAllowedSize: 10 * 1024 * 1024);
+    using var ms = new MemoryStream();
+    await stream.CopyToAsync(ms);
+    var bytes = ms.ToArray();
+    
+    // Extract dimensions from PNG header (bytes 16-23)
+    if (bytes[0] == 0x89 && bytes[1] == 0x50 && bytes[2] == 0x4E && bytes[3] == 0x47)
+    {
+        imageWidth = (bytes[16] << 24) | (bytes[17] << 16) | (bytes[18] << 8) | bytes[19];
+        imageHeight = (bytes[20] << 24) | (bytes[21] << 16) | (bytes[22] << 8) | bytes[23];
+    }
+}
+```
+
+**Backend (Server-Side with ImageSharp):**
+
+```csharp
+// In FileSystemImageStorageService.cs
+public async Task<(int width, int height)> GetImageDimensionsAsync(Stream imageStream)
+{
+    if (imageStream.CanSeek)
+        imageStream.Position = 0;
+    
+    using var image = await Image.LoadAsync(imageStream);
+    return (image.Width, image.Height);
+}
+
+// In LayoutManagerController.cs
+[HttpPost("versions/{versionId:guid}/levels/with-image")]
+public async Task<ActionResult<LayoutLevelDto>> CreateLevelWithImage(
+    Guid versionId, [FromForm] string layoutLevelId, ... , IFormFile file)
+{
+    // Step 1: Extract dimensions
+    int imageWidth, imageHeight;
+    using (var stream = file.OpenReadStream())
+    {
+        (imageWidth, imageHeight) = await _imageStorageService.GetImageDimensionsAsync(stream);
+    }
+    
+    // Step 2: Create level with dimensions
+    var request = new CreateLayoutLevelRequest
+    {
+        LayoutLevelId = layoutLevelId,
+        CoordinateSystem = new CoordinateSystemInfo
+        {
+            Resolution = resolution,
+            OriginX = originX,
+            OriginY = originY,
+            ImageWidth = imageWidth,
+            ImageHeight = imageHeight,
+            BoundsMinX = 0,
+            BoundsMaxX = imageWidth * resolution,
+            BoundsMinY = 0,
+            BoundsMaxY = imageHeight * resolution
+        }
+    };
+    
+    var level = await _layoutService.CreateLevelAsync(versionId, request);
+    
+    // Step 3: Upload image
+    try
+    {
+        using (var stream = file.OpenReadStream())
+        {
+            await _imageStorageService.SaveImageAsync(level.Id, stream);
+        }
+    }
+    catch
+    {
+        // Rollback: Delete created level
+        await _layoutService.DeleteLevelAsync(level.Id);
+        throw;
+    }
+    
+    return CreatedAtAction(nameof(GetLevel), new { levelId = level.Id }, dto);
+}
+```
+
+---
+
+### 4. File Download (JavaScript Interop)
+
+**Challenge:** Download byte[] as file from Blazor WASM.
+
+**Solution:** Generate data URL and trigger download via JS
+
+```csharp
+private async Task DownloadImage()
+{
+    if (State.PreviewImage == null) return;
+    
+    var base64 = Convert.ToBase64String(State.PreviewImage);
+    var fileName = $"{State.SelectedLevel.LayoutLevelId}_background.png";
+    
+    await JS.InvokeVoidAsync("eval", 
+        $@"
+        const link = document.createElement('a');
+        link.href = 'data:image/png;base64,{base64}';
+        link.download = '{fileName}';
+        document.body.appendChild(link);
+        link.click();
+        document.body.removeChild(link);
+        ");
+}
+```
+
+**Alternative (Cleaner):**
+
+Create `wwwroot/download.js`:
+```javascript
+window.downloadFile = (fileName, base64Data) => {
+    const link = document.createElement('a');
+    link.href = `data:image/png;base64,${base64Data}`;
+    link.download = fileName;
+    document.body.appendChild(link);
+    link.click();
+    document.body.removeChild(link);
+};
+```
+
+Then in Blazor:
+```csharp
+await JS.InvokeVoidAsync("downloadFile", fileName, base64);
+```
+
+---
+
+## Extension Guide
+
+### Adding New Dialog
+
+1. **Create Dialog Component:**
+
+```razor
+@* NewFeatureDialog.razor *@
+@inject MapManagerApiService ApiService
+@inject ISnackbar Snackbar
+
+<MudDialog>
+    <DialogContent>
+        <!-- Form fields -->
+    </DialogContent>
+    <DialogActions>
+        <MudButton OnClick="Cancel">Cancel</MudButton>
+        <MudButton Color="Color.Primary" OnClick="Submit">Submit</MudButton>
+    </DialogActions>
+</MudDialog>
+
+@code {
+    [CascadingParameter] private IMudDialogInstance? MudDialog { get; set; }
+    [Parameter] public SomeDto Data { get; set; }
+    
+    private void Cancel() => MudDialog?.Cancel();
+    
+    private async Task Submit()
+    {
+        // Call API
+        // Close dialog
+        MudDialog?.Close(DialogResult.Ok(result));
+    }
+}
+```
+
+2. **Register in Parent Component:**
+
+```csharp
+private async Task OpenNewFeatureDialog()
+{
+    var dialog = await DialogService.ShowAsync<NewFeatureDialog>(
+        "Title",
+        new DialogParameters { ["Data"] = someData });
+    
+    var result = await dialog.Result;
+    
+    if (result != null && !result.Canceled)
+    {
+        Snackbar.Add("Success!", Severity.Success);
+        await RefreshData();
+    }
+}
+```
+
+---
+
+### Adding New API Endpoint
+
+1. **Backend Controller:**
+
+```csharp
+[HttpPost("custom-action")]
+public async Task<IActionResult> CustomAction([FromBody] CustomRequest request)
+{
+    var result = await _service.DoSomethingAsync(request);
+    return Ok(result);
+}
+```
+
+2. **Frontend API Service:**
+
+```csharp
+public async Task<CustomResponse> CustomActionAsync(CustomRequest request)
+{
+    var response = await _httpClient.PostAsJsonAsync(
+        $"{_baseUrl}api/layouts/custom-action", request);
+    response.EnsureSuccessStatusCode();
+    return await response.Content.ReadFromJsonAsync<CustomResponse>();
+}
+```
+
+3. **Use in State:**
+
+```csharp
+public async Task PerformCustomActionAsync(CustomRequest request)
+{
+    IsLoading = true;
+    NotifyStateChanged();
+    
+    try
+    {
+        var result = await _apiService.CustomActionAsync(request);
+        // Update state
+    }
+    finally
+    {
+        IsLoading = false;
+        NotifyStateChanged();
+    }
+}
+```
+
+---
+
+### Performance Optimization
+
+**1. Debounce Search:**
+
+```csharp
+private Timer? searchTimer;
+
+private void OnSearchKeyUp(KeyboardEventArgs e)
+{
+    searchTimer?.Dispose();
+    searchTimer = new Timer(async _ =>
+    {
+        await InvokeAsync(async () =>
+        {
+            await State.LoadLayoutsAsync(searchText);
+        });
+    }, null, 500, Timeout.Infinite); // 500ms debounce
+}
+```
+
+**2. Lazy Load Images:**
+
+```csharp
+// Only load image when level selected
+public async Task SelectLevelAsync(LayoutLevelDto level)
+{
+    SelectedLevel = level;
+    IsLoadingPreview = true;
+    NotifyStateChanged();
+    
+    // Load preview data
+    PreviewData = await _apiService.GetLayoutDataAsync(level.Id);
+    
+    // Load image separately (can be large)
+    PreviewImage = await _apiService.GetLayoutImageAsync(level.Id);
+    
+    IsLoadingPreview = false;
+    NotifyStateChanged();
+}
+```
+
+**3. Cache API Responses:**
+
+```csharp
+private Dictionary<Guid, LayoutDataDto> _previewCache = new();
+
+public async Task<LayoutDataDto> GetLayoutDataCachedAsync(Guid levelId)
+{
+    if (_previewCache.TryGetValue(levelId, out var cached))
+        return cached;
+    
+    var data = await _apiService.GetLayoutDataAsync(levelId);
+    _previewCache[levelId] = data;
+    return data;
+}
+```
+
+---
+
+## Testing
+
+### Unit Tests
+
+```csharp
+[Fact]
+public async Task CreateLevel_WithImage_ShouldExtractDimensions()
+{
+    // Arrange
+    var service = new FileSystemImageStorageService(logger);
+    using var stream = File.OpenRead("test_1024x768.png");
+    
+    // Act
+    var (width, height) = await service.GetImageDimensionsAsync(stream);
+    
+    // Assert
+    Assert.Equal(1024, width);
+    Assert.Equal(768, height);
+}
+```
+
+### Integration Tests
+
+```csharp
+[Fact]
+public async Task E2E_CreateLayoutWithLevel()
+{
+    // Create layout
+    var layout = await apiService.CreateLayoutAsync(new CreateLayoutRequest
+    {
+        LayoutId = "test",
+        LayoutName = "Test"
+    });
+    
+    // Create version
+    var version = await apiService.CreateVersionAsync(layout.Id, new CreateLayoutVersionRequest
+    {
+        Version = "1.0"
+    });
+    
+    // Create level with image
+    using var imageStream = File.OpenRead("test.png");
+    var level = await apiService.CreateLevelWithImageAsync(
+        version.Id, "floor_1", 0, 0.05, 0, 0, imageStream, "test.png");
+    
+    // Assert
+    Assert.NotNull(level);
+    Assert.Equal("floor_1", level.LayoutLevelId);
+    Assert.NotNull(level.EditorSettings);
+    Assert.True(level.EditorSettings.ImageWidth > 0);
+}
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+**1. CORS Errors:**
+```
+Access to XMLHttpRequest at 'https://localhost:5001/api/layouts' from origin 'https://localhost:5002' 
+has been blocked by CORS policy
+```
+
+**Fix:** Configure CORS in backend `Program.cs`:
+```csharp
+builder.Services.AddCors(options =>
+{
+    options.AddDefaultPolicy(policy =>
+    {
+        policy.WithOrigins("https://localhost:5002")
+              .AllowAnyMethod()
+              .AllowAnyHeader();
+    });
+});
+
+app.UseCors();
+```
+
+**2. Image Upload 413 Payload Too Large:**
+
+**Fix:** Increase max request size:
+```csharp
+// Program.cs
+builder.Services.Configure<FormOptions>(options =>
+{
+    options.MultipartBodyLengthLimit = 10 * 1024 * 1024; // 10 MB
+});
+
+// Also in web.config for IIS
+<system.webServer>
+  <security>
+    <requestFiltering>
+      <requestLimits maxAllowedContentLength="10485760" />
+    </requestFiltering>
+  </security>
+</system.webServer>
+```
+
+**3. State Not Updating:**
+
+Check:
+- Subscribed to `OnStateChanged` event?
+- Calling `StateHasChanged()` in event handler?
+- Disposed subscription to prevent memory leaks?
+
+```csharp
+protected override async Task OnInitializedAsync()
+{
+    State.OnStateChanged += StateHasChanged; // ✅
+    await State.LoadLayoutsAsync();
+}
+
+public void Dispose()
+{
+    State.OnStateChanged -= StateHasChanged; // ✅ Important!
+}
+```
+
+---
+
+## Best Practices
+
+1. **Always validate input before API calls**
+2. **Handle exceptions and show user-friendly messages**
+3. **Use loading indicators for async operations**
+4. **Dispose subscriptions and timers**
+5. **Keep components small and focused**
+6. **Extract reusable logic into services**
+7. **Use typed DTOs, avoid magic strings**
+8. **Log errors for debugging**
+9. **Test with real data (large images, many nodes)**
+10. **Profile performance for bottlenecks**
+
+---
+
+## Future Improvements
+
+- [ ] Batch operations (delete multiple levels)
+- [ ] Undo/Redo for state changes
+- [ ] Keyboard shortcuts
+- [ ] Drag & drop image upload
+- [ ] Image cropping/editing in browser

+## Overview
+
+**LayoutManager** là công cụ quản lý bản đồ (layouts) cho robot AGV/AMR. Nó cho phép:
+- Tạo và quản lý layouts với versioning
+- Upload background images (floor plans, SLAM maps)
+- Cấu hình coordinate system (resolution, origin)
+- Preview layouts với nodes, edges, stations
+- Export/Import VDMA LIF format
+
+### Key Concepts
+
+```
+Layout (Warehouse, Factory, ...)
+  └─ Version (v1.0, v2.0, ...)
+      └─ Level (floor_1, floor_2, ...)
+          ├─ Background Image (PNG)
+          ├─ Coordinate System (Resolution, Origin)
+          └─ Map Elements (Nodes, Edges, Stations)
+```
+
+**Terminology:**
+- **Layout:** Container cao nhất (e.g., "Warehouse A", "Factory Floor")
+- **Version:** Phiên bản của layout, hỗ trợ rollback/versioning
+- **Level:** Tầng/lớp của map (e.g., "Ground Floor", "Basement")
+- **Background Image:** Ảnh nền (floor plan hoặc SLAM map)
+- **Resolution:** Tỷ lệ chuyển đổi pixels → meters
+- **Origin:** Gốc tọa độ trong hệ thống (meters)

+
+## Workflows
+
+### Workflow 1: New Map from Floor Plan
+
+**Scenario:** You have a PNG floor plan, need to create navigable map.
+
+```
+1. Prepare PNG floor plan (clean, high contrast)
+   ↓
+2. Create Layout ("Factory A")
+   ↓
+3. Create Version ("1.0")
+   ↓
+4. Create Level with Image
+   - Upload floor plan PNG
+   - Set resolution (measure 1 meter = X pixels)
+   - Set origin (usually 0,0 or building corner)
+   ↓
+5. Open LayoutEditor (future)
+   - Add nodes (waypoints)
+   - Connect edges (paths)
+   - Define stations (pickup/dropoff)
+   ↓
+6. Test & Deploy
+```
+
+**Tips:**
+- Measure resolution: Put tape measure on floor, count pixels in photo
+- Typical resolution: 0.01 - 0.1 m/px
+- Origin at bottom-left corner simplifies coordinates
+
+---
+
+### Workflow 2: SLAM Map Integration
+
+**Scenario:** Robot generated SLAM map, need to import.
+
+```
+1. Export SLAM map as PNG from robot software
+   ↓
+2. Note SLAM map metadata:
+   - Resolution (from SLAM config)
+   - Origin (from SLAM config)
+   ↓
+3. Create Layout → Version → Level
+   - Upload SLAM map PNG
+   - Enter exact resolution from SLAM
+   - Enter exact origin from SLAM
+   ↓
+4. Verify alignment:
+   - Real-world distances match calculated
+   - Origin aligns with robot's coordinate system
+   ↓
+5. Add nodes at known positions
+   ↓
+6. Deploy
+```
+
+**Tips:**
+- SLAM resolution usually in config file (e.g., `resolution: 0.05`)
+- SLAM origin often in map YAML (e.g., `origin: [-10.0, -10.0, 0.0]`)
+- Verify by measuring known features (doors, walls)
+
+---
+
+### Workflow 3: Update Existing Map
+
+**Scenario:** Floor layout changed, need to update map.
+
+```
+1. Select existing Level
+   ↓
+2. Option A: Minor changes
+   - Open LayoutEditor
+   - Adjust nodes/edges
+   ↓
+   Option B: Major changes (new floor plan)
+   - Click "Replace Image"
+   - Upload new floor plan
+   - Adjust resolution/origin if needed
+   ↓
+3. Update nodes/edges to match new layout
+   ↓
+4. Test with robot
+   ↓
+5. If good: Keep version
+   If issues: Create new version, revert if needed
+```
+
+**Tips:**
+- Always test after image replacement
+- Consider creating new version for major changes
+- Keep old version as backup
+
+---
+
+### Workflow 4: Multi-Floor Building
+
+**Scenario:** Building with multiple floors.
+
+```
+Layout: "Building A"
+└─ Version: "1.0"
+   ├─ Level: "basement" (order: 0)
+   │  - Image: basement_plan.png
+   │  - Origin: (0, 0)
+   ├─ Level: "ground_floor" (order: 1)
+   │  - Image: ground_plan.png
+   │  - Origin: (0, 0)
+   └─ Level: "floor_2" (order: 2)
+      - Image: floor2_plan.png
+      - Origin: (0, 0)
+```
+
+**Key Points:**
+- Use **Level Order** to sort floors (0 = lowest)
+- Use **same resolution** for all floors if possible
+- Use **same origin** convention (e.g., SW corner of building)
+- Each level has independent image and coordinate system
+
+---
+
+## Tips & Best Practices
+
+### Image Preparation
+
+✅ **DO:**
+- Use high-resolution images (at least 1024 px on shortest side)
+- Clean floor plan (remove furniture, labels if possible)
+- High contrast (walls dark, floor light or vice versa)
+- Accurate scale (measure real-world distances)
+- PNG format (lossless, supports transparency)
+
+❌ **DON'T:**
+- Use JPEG (lossy compression, artifacts)
+- Include skewed/distorted photos (correct perspective first)
+- Mix different scales in one image
+- Use images with text overlays (remove first)
+
+### Resolution Guidelines
+
+| Environment | Typical Resolution | Notes |
+|-------------|-------------------|-------|
+| Small indoor | 0.01 - 0.02 m/px | High precision |
+| Medium indoor | 0.05 m/px | Good balance |
+| Large warehouse | 0.1 m/px | Larger area coverage |
+| Outdoor | 0.2 - 0.5 m/px | Lower precision OK |
+
+**How to measure:**
+1. Place object of known size in scene (e.g., 1m ruler)
+2. Count pixels in photo
+3. Resolution = RealSize / PixelCount
+
+**Example:**
+- Ruler: 1 meter
+- Pixels: 20 pixels
+- Resolution: 1m / 20px = 0.05 m/px
+
+### Naming Conventions
+
+**Layout IDs:**
+- Use lowercase, underscores
+- Examples: `warehouse_a`, `factory_floor_1`, `office_building_a`
+
+**Layout Names:**
+- Use Title Case, spaces OK
+- Examples: "Warehouse A", "Factory Floor 1", "Office Building A"
+
+**Versions:**
+- Semantic versioning: `Major.Minor` (e.g., 1.0, 1.1, 2.0)
+- Or date-based: `2024.12.02`
+- Or descriptive: `production`, `testing`, `backup`
+
+**Level IDs:**
+- Descriptive: `floor_1`, `basement`, `ground_floor`, `roof`
+- Or numbered: `level_0`, `level_1`, `level_2`
+
+### Version Management
+
+**When to create new version:**
+- Major layout changes (walls added/removed)
+- Complete re-mapping
+- Switching from floor plan to SLAM map
+- Before risky changes (for rollback)
+
+**When to update existing version:**
+- Minor adjustments (node positions)
+- Adding new nodes/edges
+- Tweaking resolution/origin
+- Bug fixes
+
+### Data Organization
+
+```
+Production System:
+└─ Warehouse Layout [Active]
+   ├─ v2.1 [Active] ← Current production
+   ├─ v2.0 ← Previous stable
+   └─ v1.0 ← Original
+
+Testing System:
+└─ Warehouse Layout [Active]
+   └─ v3.0-beta [Active] ← Testing new layout
+```
+
+**Strategy:**
+- Keep 2-3 old versions for rollback
+- Use testing layout for experiments
+- Activate in production only after thorough testing
+
+### Performance Tips
+
+- **Image size:** Keep < 2048×2048 px for good performance
+- **File size:** Keep < 5 MB for fast upload
+- **Compression:** Use PNG with optimized compression
+- **Lazy loading:** Only preview shows on selection (not all at once)
+
+### Troubleshooting
+
+**Problem: Image looks distorted**
+- Cause: Wrong aspect ratio or preserveAspectRatio setting
+- Fix: Check image dimensions, re-upload if needed
+
+**Problem: Coordinates don't match reality**
+- Cause: Wrong resolution or origin
+- Fix: Measure real-world distance, recalculate resolution
+
+**Problem: Upload fails**
+- Cause: File too large (> 10 MB) or not PNG
+- Fix: Compress image, convert to PNG
+
+**Problem: Preview blank**
+- Cause: No image uploaded or image load failed
+- Fix: Check console for errors, re-upload image

+```
+
+## 📋 Mapping Rules
+
+**InteractionNode → VDA 5050 Node**:
+- nodeId: InteractionNode.interactionNodeId
+- sequenceId: Even numbers (0, 2, 4, ...)
+- nodePosition: From InteractionNode position
+- actions: From Actions table
+
+**Edge → VDA 5050 Edge**:
+- edgeId: Edge.edgeId
+- sequenceId: Odd numbers (1, 3, 5, ...)
+- trajectory: From Edge.trajectory
+- maxSpeed: From Edge.maxSpeed
+
+**Action → VDA 5050 Action**:
+- actionType: Action.actionType
+- blockingType: Action.blockingType
+- actionParameters: Action.actionParameters
+
+## 🚗 Vehicle Type Filtering
+
+**Filtering Logic**:
+- Load InteractionNodes for each station

+
+### What is RobotNet10?
+AMR fleet management system with **RobotApp** (on robots) and **FleetManager** (on server), communicating via **MQTT/VDA 5050**.
+
+### Technology
+**.NET 10**, Blazor Web App, MQTT, **SQL Server** (FleetManager), **SQLite** (RobotApp), VDA 5050 v2.1.0, VDMA LIF
+
+### Project Status
+📝 **Documentation Phase** - Architecture complete, implementation starting
+
+---
+
+## 👤 Quick Start by Role / Bắt đầu Theo Vai trò
+
+### 🤖 For AI Agents
+
+**1. Read NOW** (15 min):
+[AI Collaboration Guide](ai-guide/README.md) - **MANDATORY**
+
+**2. Skim** (10 min):
+- [Architecture Overview](architecture/README.md)
+- [VDA 5050 Integration](vda5050/README.md)
+
+**3. Start coding** with patterns from AI Guide
+
+**Key points for AI**:
+- ✅ Use exact VDA 5050 field names (e.g., `orderId` not `OrderId`)
+- ✅ Always async/await for I/O
+- ✅ Constructor injection for dependencies
+- ✅ Structured logging with parameters
+- ✅ Validate all VDA 5050 messages
+
+---
+
+### 👨‍💻 For Developers
+
+**Step 1: Setup Environment** (30-45 min)
+
+```bash
+# Install .NET 10
+# Windows: winget install Microsoft.DotNet.SDK.10
+# Linux: see Development Guide
+
+# Clone repo
+git clone https://github.com/your-org/RobotNet10.git
+cd RobotNet10
+
+# Install MQTT broker (Mosquitto)
+# Windows: winget install EclipseFoundation.Mosquitto
+# Linux: sudo apt install mosquitto
+
+# Install SQL Server (for FleetManager)
+# Windows: SQL Server Express or Developer Edition
+# Linux: See Microsoft SQL Server on Linux docs
+
+# Note: RobotApp uses SQLite (no installation needed)
+```
+
+**Step 2: Read Docs** (30 min)
+- [Development Guide](development/README.md) - Full setup
+- [Architecture Overview](architecture/README.md) - System design
+
+**Step 3: Choose Component**
+- Working on robot? → [RobotApp Docs](robotapp/README.md)
+- Working on server? → [FleetManager Docs](fleetmanager/README.md)
+
+**Step 4: Setup ScriptEngine DLLs** (Required for RobotApp)
+
+ScriptEngine cần load các DLL từ thư mục `dlls`. Bạn cần copy các file sau vào thư mục `bin/Debug/net10.0/dlls`:
+
+```bash
+# Tạo thư mục dlls nếu chưa có
+mkdir -p srcs/RobotApp/bin/Debug/net10.0/dlls
+
+# Copy .NET runtime assemblies
+# Thay $DOTNET_VERSION bằng phiên bản .NET 10 của bạn (ví dụ: 10.0.0)
+# Windows PowerShell:
+$DOTNET_VERSION = (dotnet --version)
+Copy-Item "$env:ProgramFiles\dotnet\shared\Microsoft.NETCore.App\$DOTNET_VERSION\System.Private.CoreLib.dll" -Destination "srcs/RobotApp/bin/Debug/net10.0/dlls/"
+Copy-Item "$env:ProgramFiles\dotnet\shared\Microsoft.NETCore.App\$DOTNET_VERSION\System.Runtime.dll" -Destination "srcs/RobotApp/bin/Debug/net10.0/dlls/"
+
+# Linux/Mac:
+DOTNET_VERSION=$(dotnet --version)
+cp "$HOME/.dotnet/shared/Microsoft.NETCore.App/$DOTNET_VERSION/System.Private.CoreLib.dll" srcs/RobotApp/bin/Debug/net10.0/dlls/
+cp "$HOME/.dotnet/shared/Microsoft.NETCore.App/$DOTNET_VERSION/System.Runtime.dll" srcs/RobotApp/bin/Debug/net10.0/dlls/
+
+# Copy project DLLs (sau khi build)
+cp srcs/RobotNet10/Commons/RobotNet10.Script/bin/Debug/net10.0/RobotNet10.Script.dll srcs/RobotApp/bin/Debug/net10.0/dlls/
+cp srcs/RobotNet10/RobotApp/RobotNet10.RobotApp.Script/bin/Debug/net10.0/RobotNet10.RobotApp.Script.dll srcs/RobotApp/bin/Debug/net10.0/dlls/
+```
+
+**Lưu ý**: 
+- Thư mục `dlls` phải được tạo trong `bin/Debug/net10.0/` sau khi build lần đầu
+- Các DLL này cần được copy lại mỗi khi rebuild project
+- Có thể tự động hóa bằng build script hoặc post-build event
+
+**Step 5: Start Coding**
+```bash
+cd srcs/RobotApp
+dotnet run
+# Access: http://localhost:5000
+```
+
+---
+
+### 👷 For System Integrators
+
+**1. Understand System** (45 min):
+- [Architecture Overview](architecture/README.md)
+- [VDA 5050 Integration](vda5050/README.md)
+
+**2. Check Compatibility**:
+- Your system supports MQTT? ✅
+- Your system supports VDA 5050 v2.1.0? ✅ (Backward compatible with v2.0.0)
+
+**3. Integration Points**:
+- **MQTT Broker**: localhost:1883 (or your broker)
+- **Topics**: `uagv/v2/{manufacturer}/{serialNumber}/*`
+- **QoS**: Order/InstantActions (QoS 1), State/Viz (QoS 0)
+
+**4. Test Integration**:
+```bash
+# Subscribe to robot states
+mosquitto_sub -h localhost -t "uagv/v2/RobotNet10/+/state" -v
+
+# Publish test order
+mosquitto_pub -h localhost -t "uagv/v2/RobotNet10/ROBOT001/order" -f order.json
+```
+
+---
+
+## 📋 Common Tasks / Nhiệm vụ Thường gặp
+
+### Task: Run the System Locally
+
+```bash
+# Terminal 1: Start MQTT Broker
+mosquitto -v
+
+# Terminal 2: Start FleetManager
+cd srcs/FleetManager
+dotnet run
+# Access: http://localhost:5100
+
+# Terminal 3: Setup ScriptEngine DLLs (Required for RobotApp)
+# Xem Step 4 ở trên để biết cách copy DLLs vào bin/Debug/net10.0/dlls/
+
+# Terminal 4: Start RobotApp (simulate robot)
+cd srcs/RobotApp
+dotnet run
+# Access: http://localhost:5000
+```
+
+**Important**: RobotApp yêu cầu setup ScriptEngine DLLs trước khi chạy (xem Step 4 ở trên).
+
+### Task: Implement VDA 5050 Order Handler
+
+**1. Check spec**: [VDA 5050 Integration](vda5050/README.md)
+
+**2. Create model** (if not exists):
+```csharp
+// In Shared/VDA5050/Models/Order.cs
+public class Order
+{
+    [JsonPropertyName("orderId")]
+    public string OrderId { get; set; }
+    // ... match VDA 5050 exactly
+}
+```
+
+**3. Create handler**:
+```csharp
+// In RobotApp/Services/VDA5050/OrderHandler.cs
+public class OrderHandler : IOrderHandler
+{
+    public async Task<bool> HandleOrderAsync(Order order)
+    {
+        // 1. Validate
+        // 2. Process
+        // 3. Execute
+    }
+}
+```
+
+**4. Register in DI**:
+```csharp
+// In Program.cs
+builder.Services.AddScoped<IOrderHandler, OrderHandler>();
+```
+
+### Task: Add New Database Entity
+
+**1. Create model**:
+```csharp
+public class Robot
+{
+    public Guid Id { get; set; }
+    public string SerialNumber { get; set; }
+    // ...
+}
+```
+
+**2. Add to DbContext**:
+```csharp
+public class FleetDbContext : DbContext
+{
+    public DbSet<Robot> Robots { get; set; }
+}
+```
+
+**3. Create migration**:
+```bash
+dotnet ef migrations add AddRobotEntity
+dotnet ef database update
+```
+
+### Task: Debug MQTT Messages
+
+**1. Monitor all topics**:
+```bash
+mosquitto_sub -h localhost -t "#" -v
+```
+
+**2. Test specific robot**:
+```bash
+# Subscribe to state
+mosquitto_sub -h localhost -t "uagv/v2/RobotNet10/ROBOT001/state" -v
+
+# Publish order
+echo '{"orderId":"TEST-001","orderUpdateId":0}' | \
+  mosquitto_pub -h localhost -t "uagv/v2/RobotNet10/ROBOT001/order" -l
+```
+
+**3. Check logs**:
+```csharp
+_logger.LogDebug("MQTT message received: Topic={Topic}", topic);
+```
+
+---
+
+## 🆘 Quick Troubleshooting / Xử lý Nhanh
+
+### MQTT Connection Failed
+```bash
+# Check Mosquitto running
+# Windows: sc query mosquitto
+# Linux: sudo systemctl status mosquitto
+

+
+## DEFAULT CONFIGURATIONS
+
+All default values with detailed justifications.
+
+---
+
+### 1. Robot Physical Configuration
+
+```csharp
+public static class DefaultConfigurations
+{
+    public static RobotPhysicalConfig Physical => new()
+    {
+        // Wheelbase: Distance between left and right wheels
+        // Typical for small indoor robot: 0.3-0.5m
+        // Affects: Turning radius, stability
+        Wheelbase = 0.35f,  // meters
+        
+        // Wheel radius: Affects odometry calculations
+        // Typical: 0.05-0.1m for small robots
+        WheelRadius = 0.075f,  // meters
+        
+        // Max linear velocity: User-specified
+        MaxLinearVelocity = 1.5f,  // m/s
+        
+        // Max angular velocity: Calculated from max linear velocity
+        // ω_max ≈ 2 * v_max / wheelbase
+        // Conservative estimate: 2 * 1.5 / 0.35 ≈ 8.57 rad/s
+        // Use 6 rad/s for safety margin (~343°/s)
+        MaxAngularVelocity = 6.0f,  // rad/s
+        
+        // Max linear acceleration: For smooth motion
+        // 1.0 m/s² means 0 → 1.5 m/s in 1.5 seconds
+        // Typical range: 0.5-2.0 m/s²
+        MaxLinearAcceleration = 1.0f,  // m/s²
+        
+        // Max angular acceleration: User-specified
+        MaxAngularAcceleration = 1.0f,  // rad/s²
+        
+        // Robot mass: Estimated for small mobile robot
+        Mass = 25.0f  // kg
+    };
+}
+```
+
+---
+
+### 2. Control Timing Configuration
+
+```csharp
+public static ControlTimingConfig Timing => new()
+{
+    // Control loop frequency: 50Hz (20ms per cycle)
+    // Justification:
+    // - 10Hz: Too slow, robot will oscillate
+    // - 50Hz: Optimal for indoor navigation (balance performance/CPU)
+    // - 100Hz: Better but requires more CPU, marginal gains
+    // - 200Hz+: Overkill for this application
+    ControlLoopFrequency = 50,  // Hz
+    
+    // Encoder sampling: Match or exceed control frequency
+    EncoderSamplingRate = 50,  // Hz
+    
+    // Motor command rate: Match control frequency
+    MotorCommandRate = 50  // Hz
+};
+```
+
+---
+
+### 3. PID Controller Configuration
+
+```csharp
+public static VelocityPIDConfig PID => new()
+{
+    // Kp: Proportional gain
+    // Higher Kp = faster response but more overshoot
+    // Starting point: 0.8 (moderate response)
+    // Tuning range: 0.1-5.0
+    Kp = 0.8f,
+    
+    // Ki: Integral gain
+    // Eliminates steady-state error
+    // Keep small to avoid windup
+    // Starting point: 0.1
+    // Tuning range: 0.0-2.0
+    Ki = 0.1f,
+    
+    // Kd: Derivative gain
+    // Dampens oscillations, smooths response
+    // Starting point: 0.05 (gentle damping)
+    // Tuning range: 0.0-1.0
+    Kd = 0.05f,
+    
+    // Velocity limits
+    MaxVelocity = 1.5f,  // m/s (from physical config)
+    MinVelocity = 0.1f,  // m/s (minimum for robot to move)
+    
+    // Anti-windup: Prevent integral term from growing unbounded
+    IntegralWindupLimit = 0.5f,  // m/s
+    
+    // Output saturation: Ensure output stays within limits
+    OutputSaturationEnabled = true
+};
+```
+
+**PID Tuning Guidelines:**
+- Start with Kp only (Ki=0, Kd=0), increase until oscillation
+- Reduce Kp to 60% of oscillation value
+- Add Kd to dampen remaining oscillation
+- Add Ki last, only if steady-state error exists
+
+---
+
+### 4. Velocity Estimator Configuration
+
+```csharp
+public static VelocityEstimatorConfig Estimator => new()
+{
+    // Alpha filter: Exponential moving average for encoder
+    // Lower α (0.1-0.2): More filtering, more lag
+    // Higher α (0.3-0.4): Less filtering, more responsive
+    // Recommended: 0.3 for balance
+    AlphaFilter = 0.3f,
+    
+    // Blend ratio bounds
+    MinBlendRatio = 0.15f,  // Min 15% model, 85% encoder
+    MaxBlendRatio = 0.8f,   // Max 80% model, 20% encoder
+    DefaultBlendRatio = 0.6f,  // Start with 60% model
+    
+    // Adaptive blending thresholds
+    GoodTrackingThreshold = 0.12f,  // < 12% error
+    ModerateTrackingThreshold = 0.3f,  // < 30% error
+    
+    // CORRECTED blend ratios (based on architecture review):
+    // Good tracking → trust encoder more (model prediction matches reality)
+    GoodTrackingBlend = 0.3f,  // 30% model, 70% encoder
+    
+    // Moderate tracking → balanced
+    ModerateTrackingBlend = 0.5f,  // 50-50 blend
+    
+    // Poor tracking → trust model more (encoder may have slip)
+    PoorTrackingBlend = 0.7f,  // 70% model, 30% encoder
+    
+    // Confidence decay: How fast confidence drops
+    // 0.98 = slow decay (1% per cycle at 50Hz = ~2s to halve)
+    // 0.95 = medium decay
+    // 0.90 = fast decay
+    ConfidenceDecayRate = 0.98f,
+    
+    // Minimum confidence floor
+    MinConfidence = 0.3f  // Never go below 30%
+};
+```
+
+---
+
+### 5. Pure Pursuit Configuration
+
+```csharp
+public static PurePursuitConfig PurePursuit => new()
+{
+    // Lookahead minimum: Smallest lookahead distance
+    // Too small: Oscillation, overshoot corners
+    // Too large: Cuts corners, poor tracking
+    // Recommended: 0.2-0.4m for indoor robot
+    LookaheadMin = 0.3f,  // meters
+    
+    // Kdd: Lookahead velocity scaling factor
+    // lookahead = LookaheadMin + Kdd * |velocity|
+    // Kdd = 1.0 means 1 second lookahead time
+    // Kdd = 0.5 means 0.5 second lookahead
+    // Recommended: 0.8-1.5
+    Kdd = 1.0f,  // seconds
+    
+    // Lookahead maximum: Cap lookahead distance
+    // Prevents looking too far ahead at high speeds
+    // Recommended: 1.5-3.0m
+    LookaheadMax = 2.0f  // meters
+};
+```
+
+**Pure Pursuit Tuning Guidelines:**
+- Increase Kdd for smoother, more predictive tracking
+- Decrease Kdd for tighter, more reactive tracking
+- Increase LookaheadMin if robot oscillates
+- Decrease LookaheadMin if robot cuts corners
+

+
+### 6. Path Following Configuration
+
+```csharp
+public static PathFollowingConfig PathFollowing => new()
+{
+    // Waypoint tolerance: How close to consider waypoint "reached"
+    WaypointTolerance = 0.15f,  // 15cm
+    
+    // Final goal tolerance: Tighter tolerance for final goal
+    FinalGoalTolerance = 0.05f,  // 5cm
+    
+    // Goal heading tolerance: Acceptable heading error at goal
+    GoalHeadingTolerance = 5f * MathF.PI / 180f,  // 5 degrees
+    
+    // Stop distance: When to start preparing to stop
+    StopDistance = 0.1f,  // 10cm before goal
+    
+    // Stop velocity: Threshold to consider robot "stopped"
+    StopVelocity = 0.05f  // 5cm/s
+};
+```
+
+---
+
+### 7. Safety Configuration
+
+```csharp
+public static SafetyConfig Safety => new()
+{
+    // Max cross-track error before abort
+    // 0.5m is reasonable for 10x20m indoor space
+    MaxCrossTrackError = 0.5f,  // meters
+    
+    // Max heading error before abort
+    // 45° means robot is severely off course
+    MaxHeadingError = 45f * MathF.PI / 180f,  // radians
+    
+    // Sustained error duration before abort
+    // 3 seconds allows recovery from temporary issues
+    MaxTrackingErrorDuration = 3000,  // milliseconds
+    
+    // Obstacle safety distances (for future sensors)
+    MinObstacleDistance = 0.3f,  // 30cm emergency stop
+    SafetyStopDistance = 0.5f,   // 50cm slow down
+    
+    // Emergency deceleration limit
+    EmergencyStopDeceleration = 2.0f  // m/s²
+};
+```
+
+---
+
+### 8. Acceptance Criteria Configuration
+
+```csharp
+public static AcceptanceCriteria Criteria => new()
+{
+    // PRIMARY: Tracking Accuracy (50% weight)
+    // Cross-track error RMS: 10cm is good for indoor robot
+    MaxCrossTrackErrorRMS = 0.10f,  // meters
+    
+    // Peak CTE: Allow double RMS as occasional spike
+    MaxCrossTrackErrorPeak = 0.20f,  // meters
+    
+    // Heading error: 10° RMS is acceptable
+    MaxHeadingErrorRMS = 10f * MathF.PI / 180f,  // radians
+    
+    // Goal position error: 5cm final accuracy
+    MaxGoalPositionError = 0.05f,  // meters
+    
+    // Goal heading error: 5° final accuracy
+    MaxGoalHeadingError = 5f * MathF.PI / 180f,  // radians
+    
+    // SECONDARY: Smoothness (30% weight)
+    // Max jerk: 5 m/s³ is smooth for human comfort
+    MaxJerk = 5.0f,  // m/s³
+    
+    // Max angular jerk: 10 rad/s³
+    MaxAngularJerk = 10.0f,  // rad/s³
+    
+    // TERTIARY: Efficiency (20% weight)
+    // Path length ratio: <15% deviation from optimal
+    MaxPathLengthRatio = 1.15f,  // 115% of optimal
+    
+    // Success rate: 90% of runs should pass
+    MinSuccessRate = 0.90f  // 90%
+};
+```
+
+---
+
+### 9. Scoring Weights

+```csharp
+public static ScoringWeights Weights => new()
+{
+    // How much each category contributes to overall score
+    TrackingAccuracy = 0.5f,  // 50%
+    Smoothness = 0.3f,        // 30%
+    Efficiency = 0.2f         // 20%
+};
+```
+
+---
+

+    var avgInterval = intervals.Average();
+    var actualFrequency = 1000.0 / avgInterval;
+    
+    Assert.InRange(actualFrequency, 48, 52); // 50Hz ± 2Hz
+}
+```
+
+---
+
+### 4. End-to-End Tests
+
+**Manual Test Plan:**
+
+1. **Happy Path Test**
+   - Load default config
+   - Run straight line test
+   - Verify metrics displayed
+   - Save configuration
+   - Reload and verify
+
+2. **Error Handling Test**
+   - Set invalid parameter (Kp = 100)
+   - Attempt to run test
+   - Verify error message shown
+   - Verify test doesn't start
+
+3. **Real-time Update Test**
+   - Start test
+   - Verify UI updates at ~10Hz
+   - Pause test
+   - Verify pause works
+   - Resume and complete
+
+4. **Comparison Test**
+   - Create 2 configs
+   - Run comparison
+   - Verify side-by-side display
+   - Export results

+---
+
+## 2. SYSTEM CONTEXT
+
+### 2.1. Robot Overview
+
+**Robot Type:** Differential Drive Mobile Robot  
+**Physical Characteristics:**
+- Wheelbase: 0.35m (distance between left/right wheels)
+- Wheel radius: 0.075m
+- Mass: ~25kg
+- Max linear velocity: 1.5 m/s
+- Max angular velocity: 6 rad/s
+- Max linear acceleration: 1.0 m/s²
+- Max angular acceleration: 1.0 rad/s²
+
+**Operating Environment:**
+- Indoor spaces (smooth floors)
+- Test area: 10m × 20m
+- No dynamic obstacles during tuning
+
+### 2.2. Control System Architecture
+
+The robot uses a **hierarchical control structure**:
+
+```
+Goal Position
+    ↓
+[Distance-based PID] → Linear Velocity (v_max)
+    ↓
+[Velocity Estimator] → Estimated Velocity (v_hybrid)
+    ↓                          ↓
+    └───────→ [Pure Pursuit] ←─┘
+                  ↓
+            Angular Velocity (ω)
+                  ↓
+    [Combine (v_max, ω)] → (v_cmd, ω_cmd)
+                  ↓
+    [Differential Kinematics] → (wheel_left, wheel_right)
+                  ↓
+            Motor Commands
+```
+
+**Controller Descriptions:**
+
+1. **Distance-based PID Controller:**
+   - **Input:** Distance to goal (error = distance_to_goal)
+   - **Output:** Maximum linear velocity (v_max)
+   - **Logic:** 
+     - If distance > 5m: return max velocity (1.5 m/s)
+     - If distance ≤ 5m: PID control
+     - If velocity < min velocity: return min velocity
+   - **Parameters to tune:** Kp, Ki, Kd
+
+2. **Velocity Estimator:**
+   - **Purpose:** Combine encoder measurements with kinematic model for accurate velocity estimation
+   - **Method:** Adaptive blending based on tracking quality
+   - **Model:** First-order system response
+     ```
+     v_predicted = v_actual + (v_cmd - v_actual) × (1 - e^(-t_eff/τ))
+     where t_eff = t_ahead - delay
+     ```
+   - **Blending:** 
+     ```
+     v_hybrid = blend_ratio × v_model + (1 - blend_ratio) × v_encoder
+     ```
+   - **Adaptive Logic:**
+     - Good tracking (error < 12%): blend_ratio = 0.3 (trust encoder 70%)
+     - Moderate tracking (error < 30%): blend_ratio = 0.5
+     - Poor tracking (error ≥ 30%): blend_ratio = 0.7 (trust model 70%)
+   - **Parameters to tune:** AlphaFilter, blend ratios, confidence decay rate
+
+3. **Pure Pursuit Controller:**
+   - **Input:** Current position, v_hybrid, reference path
+   - **Output:** Angular velocity (ω)
+   - **Lookahead calculation:**
+     ```
+     lookahead = clamp(
+         LookaheadMin + Kdd × |v_hybrid|,
+         LookaheadMin,
+         LookaheadMax
+     )
+     lookahead *= confidence  // Reduce if estimator confidence is low
+     ```
+   - **Parameters to tune:** Kdd, LookaheadMin, LookaheadMax
+
+### 2.3. Tuning Challenges
+
+**Current State:**
+- Manual tuning takes days per robot
+- No systematic approach to parameter selection
+- Difficult to validate performance across scenarios
+- Parameters tuned for one trajectory may fail on others
+
+**Desired State:**
+- Semi-automated tuning process
+- Data-driven parameter optimization
+- Cross-scenario validation
+- Reproducible results with confidence metrics

+## 📝 NOTES
+
+### Known Issues
+
+1. **Validation Logic**: ParameterManager validation có logic `GoodTrackingBlend < PoorTrackingBlend` - có thể cần review lại logic này
+2. **Metrics Calculation**: Một số edge cases có thể return NaN - cần handle better
+3. **Test Data**: TestHelpers.CreateTelemetryHistory() có thể cần improve để có realistic timestamps
+
+### Recent Fixes (2026-01-27)
+
+1. **DI Container Fix**: Fixed ITestExecutor registration - changed from concrete class to interface registration
+2. **Entity Framework Configuration**: 
+   - Added JSON conversion cho all complex types trong NavigationParameterSet
+   - Configured proper enum conversions (TestStatus, ViolationType, ViolationSeverity)
+   - Added optimized indexes cho performance
+   - Configured proper relationships với cascade delete
+   - Added MaxLength constraints cho string properties
+3. **Project Structure**: Created NavigationTune.Shared project để decouple frontend from backend
+4. **Build Issues**: Fixed all compilation errors related to namespace changes và missing references
+
+### Design Decisions
+
+1. **Abstract Class Persistence**: Sử dụng `TestScenarioEntity` với JSON serialization thay vì EF Core TPH
+2. **Simplified Controllers**: PurePursuit và VelocityEstimator được simplified với custom DTOs
+3. **Adapter Pattern**: Sử dụng adapters để decouple từ RobotApp dependencies
+

+## 📚 PARAMETER REFERENCE
+
+### Pure Pursuit Configuration
+
+#### **Basic Lookahead Parameters**
+
+##### `LookaheadMin` (meters)
+**Default:** 0.3m
+**Meaning:** Điểm gần nhất phía trước mà robot hướng đến
+
+**↑ Tăng (0.4-0.6m):**
+- ✓ Smoother tracking trên đường thẳng
+- ✓ Ít reactive, predictive hơn
+- ✗ Có thể cắt góc trên curves
+- ✗ Kém chính xác ở low speed
+
+**↓ Giảm (0.2-0.25m):**
+- ✓ Tracking curves chặt hơn
+- ✓ Chính xác hơn ở low speed
+- ✗ Jittery/oscillation nhiều hơn
+- ✗ Nhạy với noise
+
+**Tuning Tips:**
+- Warehouse AGV: 0.4-0.5m (smooth)
+- Tight spaces: 0.25-0.3m (precision)
+- Start: 0.3m (balanced)
+
+**UI Location:** `Pure Pursuit Tab > Basic Lookahead > LookaheadMin`
+
+---
+
+##### `Kdd` (seconds)
+**Default:** 1.0s
+**Formula:** `lookahead = LookaheadMin + Kdd × |velocity|`
+
+**↑ Tăng (1.2-1.5s):**
+- ✓ Look xa hơn ở high speed → smoother
+- ✓ Tốt cho fast robots (>1.5 m/s)
+- ✗ Có thể quá predictive (overshoot)
+
+**↓ Giảm (0.7-0.9s):**
+- ✓ Reactive control hơn
+- ✓ Tốt cho slow robots
+- ✗ Jittery ở high speed
+
+**Tuning Tips:**
+- Check formula: At 1.0m/s → lookahead = 0.3 + 1.0×1.0 = 1.3m
+- Slow robot (<0.5 m/s): Kdd = 0.8-1.0
+- Fast robot (>1.5 m/s): Kdd = 1.2-1.5
+
+**UI Location:** `Pure Pursuit Tab > Basic Lookahead > Kdd`
+
+---
+
+##### `LookaheadMax` (meters)
+**Default:** 2.0m
+**Meaning:** Upper limit cho lookahead distance
+
+**↑ Tăng (2.5-3.0m):**
+- ✓ Very smooth ở high speed
+- ✓ Tốt cho long straight paths
+- ✗ Cắt góc aggressive
+- ✗ Phản ứng chậm với path changes
+
+**↓ Giảm (1.5-1.8m):**
+- ✓ Tighter path following
+- ✓ Tốt cho complex paths
+- ✗ Kém smooth ở high speed
+
+**Tuning Tips:**
+- Must be: `LookaheadMax > LookaheadMin + Kdd × MaxVelocity`
+- Example: MaxVel=1.5m/s → need ≥ 0.3+1.0×1.5 = 1.8m
+
+**UI Location:** `Pure Pursuit Tab > Basic Lookahead > LookaheadMax`
+
+---
+
+#### **Adaptive Lookahead Parameters** (NEW in v2.0)
+
+##### `GoalRegionDistance` (meters)
+**Default:** 1.5m
+**Meaning:** Bắt đầu giảm lookahead khi trong khoảng này từ goal
+
+**How it works:**
+```
+Distance > 1.5m: lookahead = 100% (normal)
+Distance = 1.0m: lookahead = 83%
+Distance = 0.5m: lookahead = 67%
+Distance = 0.0m: lookahead = 50%
+```
+
+**↑ Tăng (2.0-3.0m):**
+- ✓ Earlier precision mode
+- ✓ Smoother deceleration
+- ✗ Slower overall
+
+**↓ Giảm (0.8-1.2m):**
+- ✓ Faster approach
+- ✗ Abrupt gần goal
+
+**Tuning Tips:**
+- Fast robot: Tăng (need more brake distance)
+- Short paths: 1.0-1.5m
+- Long paths: 2.0-2.5m
+
+**UI Location:** `Pure Pursuit Tab > Adaptive > GoalRegionDistance`
+
+---
+
+##### `KCurvature`
+**Default:** 2.0
+**Formula:** `curvatureFactor = 1 / (1 + KCurvature × curvature)`
+
+**How it works:**
+```
+Straight path (k=0):   curvatureFactor = 1.0 (100% lookahead)
+Gentle curve (k=0.5):  curvatureFactor = 0.67 (67% lookahead)
+Sharp curve (k=1.0):   curvatureFactor = 0.33 (33% lookahead)
+```
+
+**↑ Tăng (3.0-5.0):**
+- ✓ Tighter tracking trên curves
+- ✓ Ít cắt góc
+- ✗ Có thể quá reactive
+- ✗ Oscillation trên curves
+
+**↓ Giảm (1.0-1.5):**
+- ✓ Smoother trên curves
+- ✗ Cắt góc nhiều hơn
+- ✗ Kém precise
+
+**Tuning Tips:**
+- Warehouse (gentle curves): 1.5-2.0
+- Tight spaces (sharp curves): 3.0-4.0
+- If cutting corners: Tăng KCurvature
+
+**UI Location:** `Pure Pursuit Tab > Adaptive > KCurvature`
+
+---
+
+#### **Final Approach Parameters**
+
+##### `FinalApproachThreshold` (meters)
+**Default:** 0.2m
+**Meaning:** Khoảng cách activate final approach mode
+
+**Behavior:**
+- Distance > 0.2m: Normal Pure Pursuit tracking
+- Distance ≤ 0.2m: Switch to 3-phase final approach controller
+
+**3 Phases:**
+1. **Phase 1:** Approach position (distance > 3cm)
+2. **Phase 2:** Align heading (position OK, heading error > 3°)
+3. **Phase 3:** Goal reached (both OK)
+
+**↑ Tăng (0.3-0.5m):**
+- ✓ Earlier slow down → smoother
+- ✗ Takes longer
+
+**↓ Giảm (0.1-0.15m):**
+- ✓ Faster approach
+- ✗ Abrupt/jerky
+
+**Tuning Tips:**
+- Should be: `> PositionTolerance × 3`
+- High precision: 0.3-0.5m
+- Speed priority: 0.15-0.2m
+
+**UI Location:** `Pure Pursuit Tab > Final Approach > Threshold`
+
+---
+
+##### `PositionTolerance` (meters)
+**Default:** 0.03m (3cm)
+**Meaning:** Robot cần ở gần goal bao nhiêu
+
+**↑ Tăng (0.05-0.08m):**
+- ✓ Faster goal reaching
+- ✗ Lower precision
+
+**↓ Giảm (0.01-0.02m):**
+- ✓ Higher precision
+- ✗ May never reach (nếu localization error lớn)
+
+**Critical Constraint:**
+```
+PositionTolerance >= 2 × Localization_RMS_Error
+```
+
+**Tuning Tips:**
+- Typical localization: 1-2cm → use 0.03-0.05m
+- High precision app: 0.02m (if localization allows)
+- Cannot be < localization capability
+
+**UI Location:** `Pure Pursuit Tab > Final Approach > PositionTolerance`
+
+---
+
+##### `HeadingTolerance` (degrees)
+**Default:** 3.0°
+**Meaning:** Robot heading phải align trong khoảng này
+
+**Phase 2 Behavior:**
+- Position đạt → Stop linear motion
+- Rotate in-place để align heading
+- Khi heading error < 3° → Done
+
+**↑ Tăng (5-10°):**
+- ✓ Faster completion
+- ✗ Robot may face wrong direction
+
+**↓ Giảm (1-2°):**
+- ✓ Very precise alignment
+- ✗ Takes much longer
+- ✗ May oscillate
+
+**Tuning Tips:**
+- Docking/charging: 2-3° (precision critical)
+- General navigation: 5-8°
+- No heading requirement: 10-15° (fast)
+
+**UI Location:** `Pure Pursuit Tab > Final Approach > HeadingTolerance`
+
+---
+
+### Navigation Limits
+
+##### `MaxLinearVelocity` (m/s)
+**Default:** 1.5 m/s
+**Meaning:** Top speed during navigation
+
+**Safety Check:**
+```
+Braking distance = v² / (2 × deceleration)
+At 1.5 m/s, 0.5 m/s² decel → 2.25m braking distance
+```
+
+**Tuning Tips:**
+- MUST match motor controller limits
+- Warehouse AGV: 1.0-1.5 m/s
+- Outdoor: 2.0-3.0 m/s
+- Crowded areas: 0.5-0.8 m/s
+
+**UI Location:** `Navigation Limits Tab > MaxLinearVelocity`
+

+
+## 🛠️ TROUBLESHOOTING SCENARIOS
+
+### Scenario 1: Robot Oscillates (Dao động)
+
+**Triệu chứng:**
+- ✗ Robot swing qua lại
+- ✗ Angular velocity thay đổi liên tục
+- ✗ Path không smooth
+- **Metrics:** High velocity StdDev, high jerk
+
+**Root Causes & Solutions:**
+
+| Cause | Parameter | Action | Priority |
+|-------|-----------|--------|----------|
+| Lookahead quá ngắn | `LookaheadMin` | 0.3 → 0.4m | ⭐⭐⭐ |
+| Curvature sensitivity cao | `KCurvature` | 2.0 → 1.5 | ⭐⭐ |
+| Angular gain lớn | `MaxAngularVelocity` | 1.5 → 1.2 rad/s | ⭐⭐ |
+| Signal noise | `AlphaFilter` | 0.3 → 0.2 | ⭐ |
+| PID Kd thấp | `MovePidConfig.Kd` | +0.1-0.2 | ⭐⭐ |
+
+**Step-by-Step Fix:**
+```
+1. Tăng LookaheadMin: 0.3 → 0.4m
+   └─> Test → Still oscillate?
+2. Giảm KCurvature: 2.0 → 1.5
+   └─> Test → Still oscillate?
+3. Giảm MaxAngularVelocity: 1.5 → 1.2 rad/s
+   └─> Test → Still oscillate?
+4. Increase damping: MovePidConfig.Kd +0.1
+```
+
+**Expected Improvement:**
+- Velocity StdDev: 0.3 → 0.15 m/s
+- Max Jerk: 6.0 → 3.5 m/s³
+- Overall Score: +10-15 points
+
+---
+
+### Scenario 2: Robot Cuts Corners (Cắt góc)
+
+**Triệu chứng:**
+- ✗ Robot không follow đường cong chặt
+- ✗ Cross-track error lớn trên curves
+- ✗ Shortcut qua góc
+- **Metrics:** CTE RMS > 0.10m, Path Length Ratio < 1.0
+
+**Root Causes & Solutions:**
+
+| Cause | Parameter | Action | Priority |
+|-------|-----------|--------|----------|
+| Lookahead quá dài | `LookaheadMax` | 2.0 → 1.5m | ⭐⭐⭐ |
+| Không adapt curvature | `KCurvature` | 2.0 → 3.0-4.0 | ⭐⭐⭐ |
+| Lookahead time lớn | `MaxLookaheadTimeRatio` | 2.0 → 1.5s | ⭐⭐ |
+
+**Step-by-Step Fix:**
+```
+1. Tăng KCurvature: 2.0 → 3.0
+   └─> Test on sharp curve
+2. Vẫn cut? → Giảm LookaheadMax: 2.0 → 1.8m
+   └─> Check CTE RMS improvement
+3. Fine-tune: MaxLookaheadTimeRatio: 2.0 → 1.7s
+```
+
+**Test Case:**
+- Circle 0.5m Radius (challenging)
+- Goal: CTE RMS < 0.08m
+
+---
+
+### Scenario 3: Poor Goal Precision
+
+**Triệu chứng:**
+- ✗ Robot không dừng đúng vị trí
+- ✗ Heading sai khi đến goal
+- ✗ Overshoot hoặc undershoot
+- **Metrics:** Final position error > 5cm, heading error > 5°
+
+**Diagnosis:**
+```
+Check Phase Logs:
+FA-P1: DTG=0.085m, AErr=8.3°, LV=0.15, AV=0.12
+                    ^^^^^ Heading error cao
+FA-P2: HErr=2.1°, AV=0.08 (Aligning heading)
+                    ^^^^^ Good alignment
+FA-P3: Goal reached! DTG=0.02m, HErr=1.5°
+                           ^^^^^ Position OK
+```
+
+**Root Causes & Solutions:**
+
+| Cause | Parameter | Action | Priority |
+|-------|-----------|--------|----------|
+| Position tolerance lớn | `PositionTolerance` | 0.03 → 0.02m | ⭐⭐⭐ |
+| Final approach xa | `FinalApproachThreshold` | 0.2 → 0.15m | ⭐⭐ |
+| Angular gain thấp | `FinalKdAngular` | 2.0 → 2.5-3.0 | ⭐⭐⭐ |
+| Goal region lớn | `GoalRegionDistance` | 1.5 → 1.0m | ⭐ |
+
+**Special Case: Heading Issues**
+```
+If position OK but heading wrong:
+1. Check CalculateGoalHeading() logic
+2. Tăng FinalKdAngular: 2.0 → 3.0
+3. Giảm HeadingTolerance: 3° → 2° (stricter)
+4. Increase FinalApproachMaxAngularVel: 0.3 → 0.4 rad/s (faster rotation)
+```
+
+---
+
+### Scenario 4: High Speed Instability
+
+**Triệu chứng:**
+- ✗ Không stable ở tốc độ cao
+- ✗ Overshoot nhiều
+- ✗ Hard braking
+- **Metrics:** High jerk ở cuối path, position overshoot
+
+**Root Causes & Solutions:**
+
+| Cause | Parameter | Action | Priority |
+|-------|-----------|--------|----------|
+| Lookahead không đủ xa | `LookaheadMax` | 2.0 → 2.5-3.0m | ⭐⭐⭐ |
+| Kdd quá nhỏ | `Kdd` | 1.0 → 1.2-1.5s | ⭐⭐⭐ |
+| Goal region ngắn | `GoalRegionDistance` | 1.5 → 2.0-2.5m | ⭐⭐⭐ |
+
+**Formula Check:**
+```
+Braking Distance = v² / (2 × decel)
+At 1.5 m/s, 0.5 m/s² → 2.25m
+
+GoalRegionDistance should be ≥ Braking Distance
+→ Set GoalRegionDistance = 2.5m (safety margin)
+```
+

+Completion Time (s)  12.5        11.8        -6% ✓
+```
+
+**Decision:**
+- All metrics improved → ✓ Config B is better, save it
+- Mixed results → Need further tuning
+- Worse results → Revert, try different approach
+
+---
+
+## ⚠️ BEST PRACTICES & SAFETY
+
+### 1. Tuning Safety
+
+**Safety Monitoring (Auto Abort):**
+```
+Test sẽ stop nếu:
+- Cross-track error > 0.5m
+- Heading error > 45°
+- Sustained tracking error > 3s
+- Velocity exceeds motor limits
+```
+
+**Before Tuning:**
+- ✓ Check hardware health
+- ✓ Verify sensor calibration
+- ✓ Test in safe environment
+- ✓ Have emergency stop ready
+
+### 2. Parameter Validation
+
+**Automatic Constraints:**
+```csharp
+// System validates these automatically:
+LookaheadMax > LookaheadMin
+GoodTrackingBlend < PoorTrackingBlend
+MaxLinearVelocity <= Motor_Max_Velocity
+PositionTolerance >= 2 × Localization_Error
+```
+
+**If validation fails:**
+- Red border on parameter field
+- Tooltip shows violation
+- Cannot save until fixed
+
+### 3. Incremental Changes
+
+**Rule of Thumb:**
+```
+Change 1-2 parameters per iteration
+Max change: ±30% of current value
+Test after each change
+```
+
+**Example:**
+```
+❌ Bad:
+  LookaheadMin: 0.3 → 0.6 (+100%)
+  Kdd: 1.0 → 1.5 (+50%)
+  KCurvature: 2.0 → 4.0 (+100%)
+  → Too many changes, can't isolate effect
+
+✓ Good:
+  LookaheadMin: 0.3 → 0.35 (+17%)
+  Test → Evaluate → Next change
+```
+
+### 4. Documentation
+
+**Every Configuration Should Have:**
+```json
+{
+  "Name": "Tuned_2026-02-01_v3",
+  "Description": "Increased KCurvature to 3.0 to reduce corner cutting on tight curves. Improved CTE RMS from 0.095m to 0.062m on Circle 2m scenario.",
+  "CreatedBy": "User Name",
+  "BaseConfig": "Balanced Default",
+  "TestResults": [
+    {
+      "Scenario": "Circle 2m",
+      "Score": 84,
+      "CTE_RMS": 0.062
+    }
+  ]
+}
+```
+
+### 5. Multi-Scenario Validation
+
+**Minimum Test Matrix:**
+```
+Scenario             Min Score  Critical Metrics
+───────────────────  ─────────  ────────────────────
+Straight Line 10m    > 80       CTE RMS < 0.05m
+Circle 2m Radius     > 75       CTE RMS < 0.08m
+Circle 0.5m Radius   > 65       CTE RMS < 0.12m
+```
+
+**Full Validation (Before Deployment):**
+- All 3 scenarios > thresholds
+- No safety violations
+- Smooth trajectories (visual check)
+- Repeatable results (run 3 times)
+
+---
+
+## 📖 WORKFLOW EXAMPLES
+
+### Example 1: Fix Oscillation Issue
+
+**Initial State:**
+```
+Scenario: Straight Line 10m
+Score: 68/100
+Issues:
+- Velocity StdDev: 0.32 m/s (high)
+- Max Jerk: 6.2 m/s³ (high)
+- Visual: Robot swings left-right
+```
+
+**Iteration 1:**
+```
+Change: LookaheadMin: 0.3 → 0.4m
+Reason: Increase preview distance
+Result:
+  Score: 68 → 75 (+7)
+  Velocity StdDev: 0.32 → 0.22 (-31%)
+  Still some oscillation → Continue
+```
+
+**Iteration 2:**
+```
+Change: KCurvature: 2.0 → 1.5
+Reason: Less aggressive on curves
+Result:
+  Score: 75 → 79 (+4)
+  Max Jerk: 6.2 → 4.5 (-27%)
+  Better but not perfect → Continue
+```
+
+**Iteration 3:**
+```
+Change: MovePidConfig.Kd: 0.6 → 0.8
+Reason: Add damping
+Result:
+  Score: 79 → 83 (+4)
+  Velocity StdDev: 0.22 → 0.15 (-32%)
+  Visual: Smooth tracking ✓
+  PASS! Save as "Smooth_v1"
+```
+
+**Total Time:** 25 phút (3 iterations × ~8 phút/iteration)
+
+---
+
+### Example 2: Improve Goal Precision
+
+**Initial State:**
+```
+Scenario: Docking Test
+Issues:
+- Final position error: 8cm (target: <3cm)
+- Final heading error: 6° (target: <3°)
+```
+
+**Analysis:**
+```
+Phase Logs:
+FA-P1: DTG=0.18m, AErr=12°, LV=0.20
+      └─> Slow approach OK
+FA-P2: HErr=6.2°, AV=0.15
+      └─> Heading alignment too slow
+FA-P3: Not reached (timeout)
+```
+
+**Iteration 1:**
+```
+Change: FinalKdAngular: 2.0 → 3.0
+Reason: Faster heading correction
+Result:
+  Final heading error: 6° → 3.5°
+  Better but still over target
+```
+
+**Iteration 2:**
+```
+Changes:
+  - HeadingTolerance: 3° → 2° (stricter)
+  - FinalApproachMaxAngularVel: 0.3 → 0.4 (faster rotation)
+Result:
+  Final heading error: 3.5° → 2.1° ✓
+  Final position: 8cm → 2.5cm ✓
+  PASS!
+```
+

+
+## 🔮 FUTURE FEATURES
+
+### Planned: Automated Optimization (Phase 3)
+
+**Status:** Not yet implemented
+
+**Algorithms Under Consideration:**
+- Bayesian Optimization (most promising)
+- Grid Search (exhaustive but slow)
+- Genetic Algorithm (for multi-objective)
+
+**Estimated Workflow:**
+```
+1. Select parameters to optimize
+   ☑ LookaheadMin, Kdd, KCurvature
+   ☐ (Lock other parameters)
+
+2. Define objective function
+   Minimize: 0.6×CTE_RMS + 0.2×Jerk + 0.2×Time
+
+3. Set constraints
+   LookaheadMin: [0.2, 0.6]
+   Kdd: [0.7, 1.5]
+   ...
+
+4. Run optimization (30-60 phút)
+   Progress: [████░░░░] 50% (25/50 iterations)
+
+5. Review best parameters
+   Best Score: 87 (iteration 38)
+
+6. Validate on test scenarios
+```
+
+**Timeline:** Q2 2026 (planned)
+
+---
+
+## ❓ FAQ
+
+**Q: Nên tune bao nhiêu parameters cùng lúc?**
+A: 1-2 parameters per iteration. Tune theo nhóm (Pure Pursuit → PID → Velocity).
+
+**Q: Làm sao biết tuning có hiệu quả?**
+A: Use Comparison tool. Overall Score tăng ≥5 điểm + visual improvement.
+
+**Q: Robot vẫn oscillate sau khi tăng LookaheadMin?**
+A: Try giảm KCurvature hoặc tăng PID Kd (damping).
+
+**Q: Goal precision kém dù đã giảm PositionTolerance?**
+A: Check localization error. PositionTolerance không thể < 2× localization RMS error.
+
+**Q: Cần test bao nhiêu scenarios?**
+A: Minimum 3 (Straight, Circle 2m, Circle 0.5m). Recommend 5+ for robustness.
+
+**Q: Làm sao load preset vào UI?**
+A: Configuration dropdown → Select preset name → Click "Load".
+
+**Q: Configuration comparison cho kết quả khác nhau mỗi lần?**
+A: Check randomness in test scenario. Some scenarios có stochastic elements. Run multiple times và average.
+
+**Q: Tôi có thể export configuration không?**
+A: Yes, click "Export JSON" button. File có thể import vào hệ thống khác.

+# Missions / Nhiệm vụ Dài hạn
+
+## 📋 Overview / Tổng quan
+
+Missions là long-running workflows với progress tracking, phù hợp cho các nhiệm vụ phức tạp có thể cancel và track progress.
+
+**Lưu ý quan trọng**: 
+- `Mission` = method trong script với `[Mission]` attribute (không có state machine)
+- `MissionInstance` = instance được tạo từ Mission method khi gọi `CreateMission()` (có state machine)
+- Xem chi tiết về state machine trong [StateMachine_Design.md](StateMachine_Design.md)
+
+## 🔧 Cách sử dụng / Usage
+
+```csharp
+[Mission(TotalScore = 10)]
+public async IAsyncEnumerable<MissionStatus> PickAndPlace(
+    string pickLocation,
+    string placeLocation,
+    [EnumeratorCancellation] CancellationToken ct)
+{
+    yield return new MissionStatus { Score = 1, Message = "Moving to pick" };
+    await MoveTo(pickLocation);
+
+    yield return new MissionStatus { Score = 3, Message = "Picking item" };
+    await PerformPick();
+
+    yield return new MissionStatus { Score = 5, Message = "Moving to place" };
+    await MoveTo(placeLocation);
+
+    yield return new MissionStatus { Score = 8, Message = "Placing item" };
+    await PerformPlace();
+
+    yield return new MissionStatus { Score = 10, Message = "Completed" };
+}
+```
+
+## ⚙️ Đặc điểm / Features
+
+- **IAsyncEnumerable<MissionStatus>**: Return type để track progress
+- **CancellationToken support**: Có thể cancel mission
+- **Progress tracking**: Score/TotalScore để track tiến độ
+- **Per-instance MissionGlobals**: Isolated execution cho mỗi mission instance
+- **Persist to database**: Mission history được lưu vào database
+
+## 🎛️ Mission Attributes / Thuộc tính Mission
+
+- `[Mission(TotalScore = number)]`: Định nghĩa total score cho progress tracking
+
+## 📊 Mission Status / Trạng thái Mission
+
+**ScriptMissionState Enum** (tương ứng với state machine trong [StateMachine_Design.md](StateMachine_Design.md)):
+- `Idle` (0) - MissionInstance chưa được start
+- `Running` (1) - MissionInstance đang thực thi
+- `Canceling` (2) - MissionInstance đang được cancel
+- `Pausing` (3) - MissionInstance đang được pause
+- `Paused` (4) - MissionInstance đã bị pause
+- `Resuming` (5) - MissionInstance đang được resume
+- `Canceled` (6) - MissionInstance đã bị cancel
+- `Completed` (7) - MissionInstance đã hoàn thành thành công
+- `Error` (8) - MissionInstance gặp lỗi
+
+**Lưu ý**: 
+- `Mission` là method trong script với `[Mission]` attribute (không có state machine)
+- `MissionInstance` là instance được tạo từ Mission method khi gọi `CreateMission()` (có state machine)
+- State machine quản lý state của **MissionInstance**, không phải Mission
+- Terminal states (`Completed`, `Canceled`, `Error`) là final states - khi về các state này, MissionInstance sẽ:
+  1. Lưu trạng thái, log và score vào database
+  2. Dispose MissionInstance
+
+## 🔄 Mission Management APIs / API Quản lý Mission
+
+```csharp
+// Create mission
+Guid missionId = CreateMission("DeliverPackage",
+    fromLocation: "A1",
+    toLocation: "B2");
+
+// Cancel mission
+CancelMission(missionId);
+```
+
+## 💾 Data Persistence / Lưu trữ Dữ liệu
+
+Missions được persist vào database với MissionInstances và MissionLogs tables.

+# ScriptEngine Documentation / Tài liệu ScriptEngine
+
+## 📋 Overview / Tổng quan
+
+**ScriptEngine** là shared library cho phép viết và thực thi C# scripts trực tiếp trên web mà không cần rebuild ứng dụng. Module này được dùng bởi **RobotApp** và **FleetManager** để mở rộng chức năng linh hoạt.
+
+### 🎯 Vấn đề Cần Giải quyết
+
+**Thách thức**: Trong môi trường sản xuất thực tế:
+- Mỗi robot có hành vi riêng (custom actions, sensor processing)
+- Mỗi nhà máy có quy trình khác nhau (business logic)
+- Cần tích hợp với thiết bị bên thứ 3 (conveyors, elevators, stations)
+- Không thể rebuild/redeploy app mỗi lần thay đổi logic
+
+**Giải pháp ScriptEngine**:
+- ✅ Viết C# code trực tiếp trên web browser
+- ✅ IntelliSense, diagnostics, refactoring (Monaco Editor + Roslyn)
+- ✅ Multi-file support (organize code như C# project)
+- ✅ Variables, Tasks (periodic), Missions (workflows)
+- ✅ Extension APIs (mỗi app expose custom functions)
+- ✅ Real-time updates qua SignalR
+
+### 🎪 Use Cases / Trường hợp Sử dụng
+
+**RobotApp**:
+- Custom VDA 5050 actions (pick, drop, scan, charge)
+- Robot-specific behaviors (sensor calibration, custom navigation)
+- Hardware integration (custom actuators, sensors)
+
+**FleetManager**:
+- Mission planning algorithms (optimize routes, load balancing)
+- External system integration (HTTP APIs, MQTT, OPC UA)
+- Business logic (station management, elevator control, conveyor sync)
+- Custom analytics and reporting
+

+
+### State Machine / Máy Trạng thái
+
+ScriptEngine sử dụng state machine để quản lý lifecycle của Engine, Tasks và MissionInstances.
+
+📖 **[Xem chi tiết về State Machine Architecture →](StateMachine_Design.md)**
+
+**Tóm tắt**:
+- **Engine State Machine**: Quản lý trạng thái của ScriptEngine (Initializing → Idle → Building → Ready → Starting → Running → Stopping)
+- **Task State Machine**: Quản lý trạng thái của mỗi Task (Idle → Running → Pausing → Paused → Resuming → Stopping → Stopped → Error)
+- **MissionInstance State Machine**: Quản lý trạng thái của mỗi MissionInstance (Idle → Running → Pausing → Paused → Resuming → Canceling → Completed/Canceled/Error)

+# Script Files / File Script
+
+## 📋 Overview / Tổng quan
+
+ScriptEngine hỗ trợ multi-file C# scripts, cho phép tổ chức code như một C# project thực sự.
+
+## 📁 File Organization / Tổ chức File
+
+Scripts được tổ chức như C# project:
+
+```
+Scripts/
+├── Common/
+│   ├── Helpers.cs          # Shared helper methods
+│   └── Constants.cs        # Global constants
+├── Tasks/
+│   ├── MonitorTask.cs      # Periodic monitoring
+│   └── MaintenanceTask.cs  # Periodic maintenance
+└── Missions/
+    ├── DeliverMission.cs   # Delivery workflow
+    └── ChargeMission.cs    # Charging workflow
+```
+
+## ✨ Đặc điểm / Features
+
+- **Multi-file support**: Files share variables & methods
+- **Top-level statements**: Allowed trong C# scripts
+- **Class definitions**: Can define classes, structs, enums
+- **Using directives**: Supported for namespaces
+- **File system storage**: Scripts lưu trong file system
+- **Backup & Restore**: ZIP format với preserved structure
+
+## 🔒 File Locking / Khóa File
+
+- SignalR-based file locking
+- Khi user đang edit, các session khác không được sửa file
+- ScriptEngine quản lý trạng thái cho phép chỉnh sửa hay không
+- Không có realtime update file content, chỉ khi user gọi action Save mới gửi lên server

+# Security & Limitations / Bảo mật & Giới hạn
+
+## 📋 Overview / Tổng quan
+
+ScriptEngine có các giới hạn về security và metadata references để đảm bảo an toàn.
+
+## 🔒 MetadataReference Restrictions
+
+### Allowed / Được phép
+
+- `System.Runtime`
+- `System.Collections`
+- `System.Private.CoreLib`
+- `RobotNet.Script` (ScriptEngine APIs)
+- App-specific DLL
+
+### Forbidden / Không được phép

+**Not included** (for security):
+- `System.IO` (file system access)
+- `System.Net` (network - trừ khi app explicitly add)
+- `System.Reflection.Emit`
+- `System.Diagnostics.Process`
+
+## 🔐 Thread Safety / An toàn Luồng
+
+**Current Design**:
+- Variables stored in `ConcurrentDictionary` (thread-safe dictionary ops)
+- BUT: Complex operations (read-modify-write) NOT atomic
+
+**Recommendation**: User adds manual locking if needed

+# ScriptEngine State Machine Architecture / Kiến trúc State Machine cho ScriptEngine
+
+## 📋 Overview / Tổng quan
+
+Tài liệu này mô tả kiến trúc state machine cho module ScriptEngine sử dụng **Appccelerate.StateMachine**. Module ScriptEngine có 3 state machine chính:
+
+1. **TaskStateMachine** - Quản lý state của Task (periodic execution)
+2. **MissionStateMachine** - Quản lý state của Mission (long-running workflow)
+3. **EngineManagerStateMachine** - Quản lý state của ScriptEngine Manager
+
+---
+
+## 🎯 State Machine Definitions / Định nghĩa State Machine
+
+### 1. Task State Machine
+
+#### States / Trạng thái
+
+```csharp
+public enum ScriptTaskState
+{
+    Idle = 0,
+    Running,
+    Pausing,
+    Paused,
+    Resuming,
+    Stopping,
+    Stopped,
+    Error,
+}
+```
+
+#### Triggers / Sự kiện
+
+**Public Triggers** (có thể gọi từ bên ngoài):
+- `Start` - Bắt đầu task
+- `Pause` - Tạm dừng task (timer tiếp tục chạy, chỉ skip execution)
+- `Resume` - Tiếp tục task (timer đã chạy, chỉ enable execution lại)
+- `Stop` - Dừng task (dừng timer và cleanup)
+
+**Internal Triggers** (tự động fire khi operation hoàn thành):
+- `PausingCompleted` - Hoàn thành quá trình pausing
+- `ResumingCompleted` - Hoàn thành quá trình resuming
+- `StoppingCompleted` - Hoàn thành quá trình stopping
+- `ErrorOccurred` - Xảy ra lỗi
+
+#### State Transition Diagram / Sơ đồ Chuyển đổi Trạng thái
+
+```mermaid

+    [*] --> Idle
+    
+    Idle --> Running: Start
+    
+    Running --> Pausing: Pause

+    
+    Stopped --> Running: Start
+    
+    Error --> Running: Start
+    
+    note right of Running
+        Task đang chạy định kỳ
+        theo interval
+        Timer/Realtime loop đang chạy
+    end note
+    
+    note right of Paused
+        Task đã tạm dừng
+        Timer/Realtime loop vẫn chạy
+        Chỉ skip execution
+        Có thể resume hoặc stop
+    end note
+    
+    note right of Stopped
+        Task đã dừng
+        Timer/Realtime loop đã dừng
+        Có thể start lại
+    end note
+    
+    note right of Error
+        Task gặp lỗi
+        Có thể start lại
+    end note
+```
+
+---
+
+**Lưu ý về Task State Machine**:
+- Task bắt đầu ở state `Idle`
+- Khi ở `Running`, task chạy định kỳ theo interval
+- **Pause/Resume Behavior**: 
+  - Khi `Pause`: Timer/Realtime loop **vẫn tiếp tục chạy**, chỉ skip execution khi timer expire
+  - Khi `Resume`: Timer/Realtime loop **đã chạy**, chỉ enable execution lại
+  - Điều này đảm bảo timer không bị gián đoạn và có thể resume ngay lập tức
+- Các intermediate states (`Pausing`, `Resuming`, `Stopping`) được sử dụng khi có async operations
+- Từ `Stopped` hoặc `Error`, có thể `Start` lại để về `Running` (không cần về `Idle`)
+- Task có thể được pause/resume nhiều lần
+- Task có thuộc tính `AutoStart` (mặc định `true`) - khi `AutoStart = true`, task sẽ tự động start khi Engine chuyển sang `Running`
+- Khi Engine chuyển sang `Stopping`, tất cả Tasks phải stop và về `Stopped`
+- **Enable/Disable là API level, Pause/Resume là state machine level**:
+  - `Enable()` = `Resume()` - chuyển từ `Paused` → `Resuming` → `Running`
+  - `Disable()` = `Pause()` - chuyển từ `Running` → `Pausing` → `Paused`
+  - `Stopped` chỉ xảy ra khi Engine stop, không phải khi Disable
+- **Dispose**: `Dispose()` method được gọi trực tiếp, không qua state machine trigger. Dispose có thể được gọi từ bất kỳ state nào và sẽ tự động stop task nếu đang running trước khi cleanup
+
+---
+
+### 2. Mission State Machine
+
+#### States / Trạng thái
+
+```csharp

+
+**Lưu ý về Mission State Machine**:
+- **Mission vs MissionInstance**: 
+  - `Mission` là method được khai báo trong script với `[Mission]` attribute (không có state machine)
+  - `MissionInstance` là instance được tạo từ Mission method khi gọi `CreateMission()` (có state machine)
+  - State machine này quản lý state của **MissionInstance**, không phải Mission class
+- MissionInstance bắt đầu ở state `Idle`
+- Khi ở `Running`, MissionInstance thực thi IAsyncEnumerable workflow
+- Có thể pause/resume MissionInstance trong quá trình execution thông qua cơ chế `MoveNext()` của IAsyncEnumerable
+- Terminal states (`Completed`, `Canceled`, `Error`) là final states - không thể transition từ đây
+- Mỗi MissionInstance chỉ chạy một lần, sau khi complete/cancel/error thì không thể reuse
+- Để chạy lại mission, phải tạo MissionInstance mới
+- Khi Engine chuyển sang `Stopping`, các MissionInstance đang `Running` sẽ bị cancel và chờ về `Canceled`
+- **MissionInstance Lifecycle**: Khi MissionInstance về terminal states (`Completed`, `Canceled`, `Error`):
+  1. Lưu trạng thái, log và score vào database
+  2. Dispose MissionInstance

+
+**Lưu ý về Engine Manager State Machine**:
+- Engine bắt đầu ở state `Initializing` khi khởi động
+- Engine tự động chuyển từ `Initializing` sang `Idle` khi initialization hoàn thành
+- `Idle`: Scripts có thể được edit và save
+- `Building`: Compile scripts và extract metadata (Tasks, Missions, Variables). Khi build thành công, sẽ tạo lại Task và Mission từ compiled scripts
+- `Ready`: Scripts đã compiled thành công, sẵn sàng để start. **Không thể edit scripts khi ở Ready**, phải gọi `Reset` để về `Idle` mới edit được
+- `Starting`: Khi Engine vào `Starting`, các Task có `AutoStart = true` sẽ bắt đầu start
+- `Running`: Tasks và MissionInstances có thể execute. MissionInstance có thể được tạo khi Engine ở `Running`
+- `Stopping`: Engine chỉ chuyển sang `Ready` khi **TẤT CẢ** Tasks đã về `Stopped` **VÀ** **TẤT CẢ** MissionInstances không còn ở state `Running`
+- `BuildError`: Lỗi khi compile, có thể reset về Idle hoặc build lại
+- `Fault`: Lỗi hệ thống nghiêm trọng, cần reset để recovery
+- Engine chỉ có thể `Build` từ `Idle` hoặc `BuildError`. Khi `Running`, chỉ có thể gọi `Stop`
+- Khi Engine `Reset`, TaskManager và MissionManager sẽ giải phóng (dispose) tất cả Tasks và MissionInstances

+
+### State Dependencies / Phụ thuộc Trạng thái
+
+1. **EngineManager → TaskManager**:
+   - Tasks chỉ có thể chạy khi Engine ở state `Running`
+   - Khi Engine chuyển sang `Stopping`, tất cả Tasks phải stop và về `Stopped`
+   - Khi Engine ở `Starting`, các Task có `AutoStart = true` sẽ tự động start
+   - Task có thể được Enable/Disable khi Engine ở `Running` (tương đương pause/resume)
+   - Khi Engine `Reset`, tất cả Tasks sẽ bị dispose
+
+2. **EngineManager → MissionManager**:
+   - MissionInstance chỉ có thể start khi Engine ở state `Running`
+   - MissionInstance có thể được tạo khi Engine ở `Running`
+   - Khi Engine chuyển sang `Stopping`, các MissionInstance đang `Running` sẽ bị cancel và chờ về `Canceled`
+   - Engine chỉ chuyển từ `Stopping` sang `Ready` khi **TẤT CẢ** MissionInstances không còn ở state `Running`
+   - Khi Engine `Reset`, tất cả MissionInstances sẽ bị dispose
+
+3. **Task và MissionInstance độc lập**:
+   - Tasks và MissionInstances không phụ thuộc trực tiếp vào nhau
+   - Chúng có thể tương tác qua Variables và APIs
+   - Có thể chạy song song nhiều MissionInstances cùng lúc
+
+4. **Engine Lifecycle**:
+   - `Building → Ready`: Tạo lại Task và Mission từ compiled scripts
+   - `Starting`: Các Task có `AutoStart = true` bắt đầu start
+   - `Stopping → Ready`: Chờ tất cả Tasks về `Stopped` và tất cả MissionInstances không còn `Running`
+   - `Reset`: Dispose tất cả Tasks và MissionInstances
+
+---
+
+## 📝 Important Clarifications / Làm rõ Quan trọng
+
+### 1. Task Enable/Disable vs Pause/Resume
+
+**Đã làm rõ**:
+- `Enable/Disable` là **API level** (public interface cho scripts/users)
+- `Pause/Resume` là **state machine level** (internal state transitions)
+- `Enable()` = `Resume()` - chuyển từ `Paused` → `Resuming` → `Running`
+- `Disable()` = `Pause()` - chuyển từ `Running` → `Pausing` → `Paused`
+- Khi Task đang `Running` và bị `Disable()`, sẽ chuyển sang `Pausing` rồi mới về `Paused`
+- Khi Task bị `Disable`, state machine sẽ về `Paused` (không phải `Stopped`)
+- `Stopped` chỉ xảy ra khi Engine stop, không phải khi Disable
+
+### 2. Mission vs MissionInstance
+
+**Đã làm rõ**:
+- `Mission` = method trong script với `[Mission]` attribute (không có state machine)
+- `MissionInstance` = instance được tạo từ Mission (có state machine)
+- State machine quản lý state của **MissionInstance**, không phải Mission
+
+### 3. Engine Stopping → Ready Transition
+
+**Đã làm rõ**:
+- Engine chỉ chuyển từ `Stopping` sang `Ready` khi:
+  - **TẤT CẢ** Tasks đã về `Stopped`
+  - **VÀ** **TẤT CẢ** MissionInstances không còn ở state `Running`
+- Cần implement logic kiểm tra điều kiện này trước khi fire `StoppingCompleted` trigger
+
+### 4. Task AutoStart Behavior
+
+**Đã làm rõ**:
+- Task có thuộc tính `AutoStart` (mặc định `true`)
+- Khi Engine chuyển sang `Starting`, các Task có `AutoStart = true` sẽ tự động start
+- Task có `AutoStart = false` phải manually start
+
+### 5. Engine Building → Ready
+
+**Đã làm rõ**:
+- Khi Engine chuyển từ `Building` sang `Ready`, sẽ tạo lại Task và Mission từ compiled scripts
+- Các Task và MissionInstance cũ sẽ bị dispose trước đó (khi Engine Reset hoặc khi bắt đầu Building)
+- Flow: `Reset` → dispose Tasks/MissionInstances → `Building` → compile scripts → `Ready` → tạo lại Tasks/Missions từ compiled scripts
+
+### 6. Engine Reset Behavior
+
+**Đã làm rõ**:
+- Khi Engine `Reset`, TaskManager và MissionManager sẽ dispose tất cả Tasks và MissionInstances
+- Engine về `Idle`, scripts có thể được edit

+# Tasks / Nhiệm vụ Định kỳ
+
+## 📋 Overview / Tổng quan
+
+Tasks là methods chạy lặp lại theo interval định kỳ, phù hợp cho monitoring và automation đơn giản.
+
+## 🔧 Cách sử dụng / Usage
+
+```csharp
+[Task(Interval = 1000, AutoStart = true)]
+public void MonitorBattery()
+{
+    var level = GetBatteryLevel();
+    if (level < batteryThreshold)
+    {
+        Logger.Warning($"Battery low: {level}%");
+    }
+}
+
+// Async task support
+[Task(Interval = 5000, AutoStart = false)]
+public async Task CheckConnection()
+{
+    await PingServerAsync();
+    Logger.Info("Connection OK");
+}
+```
+
+## ⚙️ Đặc điểm / Features
+
+- **Timer-based execution**: 
+  - Standard: Sử dụng `System.Threading.Timer`
+  - Realtime (Linux): Sử dụng `RealtimeTimer` với dedicated thread và highest priority
+- **AutoStart option**: Task có `AutoStart = true` sẽ tự động start khi Engine chuyển sang `Starting` state (xem [StateMachine_Design.md](StateMachine_Design.md))
+- **Warning**: Nếu execution time > interval
+- **ScriptGlobals**: Reused cho tất cả executions (performance)
+- **Thread-safe**: Variables được chia sẻ thread-safe
+- **State Machine**: Task có state machine quản lý lifecycle (Idle, Running, Pausing, Paused, Resuming, Stopping, Stopped, Error)
+- **Pause/Resume**: Timer/Realtime loop tiếp tục chạy khi paused, chỉ skip execution. Resume ngay lập tức không cần restart timer
+
+## 🎛️ Task Attributes / Thuộc tính Task
+
+- `[Task(Interval = milliseconds)]`: Định nghĩa interval giữa các lần chạy
+- `[Task(Interval = milliseconds, AutoStart = true/false)]`: Tự động start khi engine ready
+
+## 🔄 Task Control APIs / API Điều khiển Task
+
+```csharp
+EnableTask("MonitoringTask");   // Tương đương task.Resume() - chuyển từ Paused → Running
+DisableTask("MaintenanceTask"); // Tương đương task.Pause() - chuyển từ Running → Paused
+```
+
+**Lưu ý**:
+- `EnableTask/DisableTask` là API level (public interface cho scripts)
+- `Pause/Resume` là state machine level (internal state transitions)
+- `EnableTask()` = `Resume()` - chuyển từ `Paused` → `Resuming` → `Running`
+- `DisableTask()` = `Pause()` - chuyển từ `Running` → `Pausing` → `Paused`
+- **Pause/Resume Behavior**: 
+  - Khi `Pause`: Timer/Realtime loop **vẫn tiếp tục chạy**, chỉ skip execution khi timer expire
+  - Khi `Resume`: Timer/Realtime loop **đã chạy**, chỉ enable execution lại
+  - Điều này đảm bảo timer không bị gián đoạn và có thể resume ngay lập tức

+# Variables / Biến Toàn cục
+
+## 📋 Overview / Tổng quan
+
+Variables là shared state được chia sẻ giữa tất cả scripts trong ScriptEngine.
+
+## 🔧 Cách sử dụng / Usage
+
+```csharp
+// Simple variable (không hiện UI)
+int counter = 0;
+string robotName = "ROBOT001";
+
+// Variable visible trong UI (read-only)
+[Variable]
+double batteryThreshold = 20.0;
+
+// Variable có thể edit từ UI
+[Variable(Writeable = true)]
+int maxSpeed = 100;
+```
+
+## ⚙️ Cách hoạt động / How It Works
+
+- Stored in `ConcurrentDictionary<string, object?>`
+- Thread-safe dictionary operations
+- Runtime-only (không persist to database)
+- Property wrappers tự động generate
+
+## 📊 Variable Attributes / Thuộc tính Variable
+
+- `[Variable]`: Variable hiển thị trong UI, read-only
+- `[Variable(Writeable = true)]`: Variable có thể edit từ UI
+- Không có attribute: Variable không hiển thị trong UI

+- **SQLite** - RobotApp local database
+- **VDA 5050** (v2.1.0) - Standard protocol (backward compatible with v2.0.0)
+- **VDMA LIF** - Map data standard
+
+### Project Status / Trạng thái Dự án
+
+**Current Phase**: 📝 Documentation & Architecture Design
+
+**What exists**:
+- ✅ Project structure defined
+- ✅ Comprehensive documentation
+- ✅ Linux RT kernel prepared
+- ⏳ Source code implementation (NOT started yet)
+
+**What doesn't exist yet**:
+- ❌ RobotApp source code
+- ❌ FleetManager source code
+- ❌ Shared libraries
+- ❌ Tests
+- ❌ Database schemas
+
+**This means**: When implementing, you'll be creating NEW code, not modifying existing code.
+
+## 🎯 Key Design Decisions / Quyết định Thiết kế Quan trọng
+
+### 1. Why VDA 5050?
+- **Interoperability**: Work with third-party systems
+- **Standardization**: Clear protocol specification
+- **Industry adoption**: Widely supported
+
+### 2. Why .NET/Blazor?
+- **Cross-platform**: Runs on Linux (robots) and Windows/Linux (server)
+- **Performance**: High-performance runtime
+- **Unified UI**: Blazor for both RobotApp and FleetManager web interfaces
+- **Strong typing**: C# type safety reduces bugs
+- **Ecosystem**: Rich libraries (MQTTnet, EF Core, etc.)
+
+### 3. Why MQTT?
+- **Lightweight**: Low overhead for IoT/robotics
+- **Publish-Subscribe**: Perfect for 1-to-many communication
+- **QoS Levels**: Reliable message delivery
+- **VDA 5050 requirement**: Standard specifies MQTT
+
+### 4. Architecture Pattern
+- **Clean Architecture**: Separation of concerns
+- **Dependency Injection**: Testable, maintainable code
+- **Async/Await**: Non-blocking I/O operations
+- **Repository Pattern**: Data access abstraction
+
+### 5. FleetManager Core Modules
+FleetManager được tổ chức thành 7 core modules:
+
+1. **Identity**: Authentication & Authorization (ASP.NET Identity, RBAC)
+2. **MapEditor**: Map management theo VDMA LIF standard (shared library)
+3. **RobotConnections**: MQTT connection management, heartbeat monitoring
+4. **RobotManager**: Robot state, order, và action management
+5. **TrafficControl**: Route calculation (A*), conflict detection & resolution
+6. **ScriptEngine**: C# scripting engine cho custom behaviors (shared library)
+7. **FleetManagerConfig**: Dynamic configuration management (runtime updates)
+
+**Important**: ScriptEngine và MapEditor là shared libraries được dùng bởi cả RobotApp và FleetManager.

+
+### Naming Conventions
+
+**Interfaces**:
+```csharp
+public interface IFleetCoordinator { }
+public interface IMissionPlanner { }
+public interface IVda5050Handler { }
+```
+
+**Services**:
+```csharp
+public class FleetCoordinator : IFleetCoordinator { }
+public class MissionPlanner : IMissionPlanner { }
+```
+
+**Models** (VDA 5050 - match standard):
+```csharp
+public class Order { }      // Exactly as in VDA 5050
+public class State { }      // Exactly as in VDA 5050
+public class Node { }       // Exactly as in VDA 5050
+```
+
+**Models** (Domain-specific):
+```csharp
+public class Robot { }
+public class Mission { }
+public class Waypoint { }
+```
+
+## 🔍 Important Patterns / Các Pattern Quan trọng
+
+### 1. Dependency Injection
+
+**Always use constructor injection**:
+```csharp
+public class FleetCoordinator : IFleetCoordinator
+{
+    private readonly ILogger<FleetCoordinator> _logger;
+    private readonly IMqttClient _mqttClient;
+    private readonly IRepository<Robot> _robotRepository;
+
+    // ✅ Correct: Constructor injection
+    public FleetCoordinator(
+        ILogger<FleetCoordinator> logger,
+        IMqttClient mqttClient,
+        IRepository<Robot> robotRepository)
+    {
+        _logger = logger;
+        _mqttClient = mqttClient;
+        _robotRepository = robotRepository;
+    }
+}
+
+// ❌ Wrong: Don't use service locator pattern
+public class BadExample
+{
+    public void DoSomething()
+    {
+        var service = ServiceLocator.Get<ISomeService>(); // Don't do this
+    }
+}
+```
+
+### 2. Async/Await
+
+**All I/O operations must be async**:
+```csharp
+// ✅ Correct
+public async Task PublishStateAsync(RobotState state)
+{
+    var message = CreateMqttMessage(state);
+    await _mqttClient.PublishAsync(message);
+}
+
+// ❌ Wrong: Blocking synchronous call
+public void PublishState(RobotState state)
+{
+    var message = CreateMqttMessage(state);
+    _mqttClient.PublishAsync(message).Wait(); // Don't do this
+}
+```
+
+### 3. Repository Pattern
+
+**Abstract data access**:
+```csharp
+public interface IRepository<T> where T : class
+{
+    Task<T> GetByIdAsync(Guid id);
+    Task<IEnumerable<T>> GetAllAsync();
+    Task<T> AddAsync(T entity);
+    Task UpdateAsync(T entity);
+    Task DeleteAsync(Guid id);
+}
+
+public class Repository<T> : IRepository<T> where T : class
+{
+    private readonly DbContext _context;
+    private readonly DbSet<T> _dbSet;
+
+    public Repository(DbContext context)
+    {
+        _context = context;
+        _dbSet = context.Set<T>();
+    }
+
+    public async Task<T> GetByIdAsync(Guid id)
+    {
+        return await _dbSet.FindAsync(id);
+    }
+    // ... other implementations
+}
+```
+
+### 4. VDA 5050 Message Handling

+**Always validate VDA 5050 messages**:
+```csharp
+public class OrderProcessor
+{
+    private readonly IVda5050Validator _validator;
+
+    public async Task<bool> ProcessOrderAsync(Order order)
+    {
+        // 1. Validate against VDA 5050 spec
+        var validationResult = _validator.ValidateOrder(order);
+        if (!validationResult.IsValid)
+        {
+            _logger.LogError("Invalid order: {Errors}", validationResult.Errors);
+            return false;
+        }
+
+        // 2. Check business logic
+        if (!IsOrderFeasible(order))
+        {
+            _logger.LogWarning("Order not feasible: {OrderId}", order.OrderId);
+            return false;
+        }
+
+        // 3. Process order
+        await ExecuteOrderAsync(order);
+        return true;
+    }
+}
+```
+
+## 🚨 Critical Implementation Guidelines / Hướng dẫn Triển khai Quan trọng
+
+### 1. VDA 5050 Compliance / Tuân thủ VDA 5050
+
+**DO**:
+- ✅ Use exact field names from VDA 5050 specification
+- ✅ Follow sequence ID ordering (nodes: even, edges: odd)
+- ✅ Validate all messages against VDA 5050 schema
+- ✅ Handle all mandatory fields
+- ✅ Implement all required message types
+
+**DON'T**:
+- ❌ Change VDA 5050 field names (e.g., don't rename `orderId` to `OrderId`)
+- ❌ Skip message validation
+- ❌ Ignore optional fields that might be used by third-party systems
+
+**Example - Correct VDA 5050 Model**:
+```csharp
+// ✅ Correct: Matches VDA 5050 exactly
+public class Order
+{
+    [JsonPropertyName("headerId")]
+    public long HeaderId { get; set; }
+
+    [JsonPropertyName("timestamp")]
+    public DateTime Timestamp { get; set; }
+
+    [JsonPropertyName("version")]
+    public string Version { get; set; }
+
+    [JsonPropertyName("manufacturer")]
+    public string Manufacturer { get; set; }
+
+    [JsonPropertyName("serialNumber")]
+    public string SerialNumber { get; set; }
+
+    [JsonPropertyName("orderId")]
+    public string OrderId { get; set; }
+
+    [JsonPropertyName("orderUpdateId")]
+    public long OrderUpdateId { get; set; }
+
+    [JsonPropertyName("nodes")]
+    public List<Node> Nodes { get; set; }
+
+    [JsonPropertyName("edges")]
+    public List<Edge> Edges { get; set; }
+}
+
+// ❌ Wrong: Field names don't match VDA 5050
+public class BadOrder
+{
+    public long Id { get; set; }           // Should be "headerId"
+    public string OrderNumber { get; set; } // Should be "orderId"
+}
+```
+
+### 2. MQTT Connection Management / Quản lý Kết nối MQTT
+
+**Implement reconnection logic**:
+```csharp
+public class MqttService
+{
+    private readonly IMqttClient _mqttClient;
+    private bool _isReconnecting;
+
+    public async Task ConnectAsync()
+    {
+        var options = new MqttClientOptionsBuilder()
+            .WithTcpServer(_config.BrokerAddress, _config.Port)
+            .WithClientId(_config.ClientId)
+            .WithCleanSession(false)
+            .WithKeepAlivePeriod(TimeSpan.FromSeconds(60))
+            .Build();
+
+        _mqttClient.DisconnectedAsync += async e =>
+        {
+            if (_isReconnecting) return;
+
+            _isReconnecting = true;
+            _logger.LogWarning("MQTT disconnected. Reconnecting...");
+
+            await Task.Delay(TimeSpan.FromSeconds(5));
+
+            try
+            {
+                await _mqttClient.ConnectAsync(options);
+                _logger.LogInformation("MQTT reconnected successfully");
+            }
+            catch (Exception ex)
+            {
+                _logger.LogError(ex, "MQTT reconnection failed");
+            }
+            finally
+            {
+                _isReconnecting = false;
+            }
+        };
+
+        await _mqttClient.ConnectAsync(options);
+    }
+}
+```
+
+### 3. Error Handling / Xử lý Lỗi
+
+**Use structured error handling**:
+```csharp
+public async Task<Result<Mission>> CreateMissionAsync(MissionRequest request)
+{
+    try
+    {
+        // Validate input
+        if (request == null)
+            return Result<Mission>.Failure("Request cannot be null");
+
+        // Business logic
+        var mission = await _missionPlanner.CreateMissionAsync(request);
+
+        if (mission == null)
+            return Result<Mission>.Failure("Failed to create mission");
+
+        // Persist
+        await _repository.AddAsync(mission);
+
+        _logger.LogInformation("Mission created: {MissionId}", mission.Id);
+        return Result<Mission>.Success(mission);
+    }
+    catch (Exception ex)
+    {
+        _logger.LogError(ex, "Error creating mission");
+        return Result<Mission>.Failure($"Error: {ex.Message}");
+    }
+}
+
+// Result class for clean error handling
+public class Result<T>
+{
+    public bool IsSuccess { get; set; }
+    public T Data { get; set; }
+    public string ErrorMessage { get; set; }
+
+    public static Result<T> Success(T data) =>
+        new Result<T> { IsSuccess = true, Data = data };
+
+    public static Result<T> Failure(string errorMessage) =>
+        new Result<T> { IsSuccess = false, ErrorMessage = errorMessage };
+}
+```
+
+### 4. Logging Best Practices / Thực hành Log tốt
+
+```csharp
+public class OrderProcessor
+{
+    private readonly ILogger<OrderProcessor> _logger;
+
+    public async Task ProcessOrderAsync(Order order)
+    {
+        // ✅ Use structured logging with parameters
+        _logger.LogInformation(
+            "Processing order: OrderId={OrderId}, UpdateId={UpdateId}, Nodes={NodeCount}",
+            order.OrderId,
+            order.OrderUpdateId,
+            order.Nodes.Count
+        );
+
+        // ❌ Don't use string interpolation in logs
+        // _logger.LogInformation($"Processing order: {order.OrderId}");
+
+        try
+        {
+            await ExecuteOrderAsync(order);
+            _logger.LogInformation("Order completed: {OrderId}", order.OrderId);
+        }
+        catch (Exception ex)
+        {
+            // ✅ Include exception and context
+            _logger.LogError(ex,
+                "Failed to process order: OrderId={OrderId}",
+                order.OrderId
+            );
+        }
+    }
+}
+```
+

+**Example**:
+```csharp
+// 1. Model (in Shared project)
+public class Order
+{
+    [JsonPropertyName("orderId")]
+    public string OrderId { get; set; }
+    // ... other fields
+}
+
+// 2. Handler (in RobotApp project)
+public interface IOrderHandler
+{
+    Task<bool> HandleOrderAsync(Order order);
+}
+
+public class OrderHandler : IOrderHandler
+{
+    private readonly ILogger<OrderHandler> _logger;
+    private readonly IVda5050Validator _validator;
+    private readonly INavigationController _navigation;
+
+    public OrderHandler(
+        ILogger<OrderHandler> logger,
+        IVda5050Validator validator,
+        INavigationController navigation)
+    {
+        _logger = logger;
+        _validator = validator;
+        _navigation = navigation;
+    }
+
+    public async Task<bool> HandleOrderAsync(Order order)
+    {
+        // Validate
+        var validationResult = _validator.ValidateOrder(order);
+        if (!validationResult.IsValid)
+        {
+            _logger.LogError("Invalid order: {Errors}", validationResult.Errors);
+            return false;

+    }
+
+    public async Task<Mission> CreateMissionAsync(MissionRequest request)
+    {
+        // Implementation
+    }
+
+    public async Task<bool> ValidateMissionAsync(Mission mission)
+    {
+        // Implementation
+    }
+}
+
+// 3. Register
+builder.Services.AddScoped<IMissionPlanner, MissionPlanner>();
+```
+
+### Task 3: Add Database Entity
+
+**Steps**:
+1. Create model class in Models/
+2. Add DbSet to DbContext
+3. Create migration
+4. Apply migration
+5. Create repository (if needed)
+6. Add seed data (if needed)
+
+**Example**:
+```csharp
+// 1. Model
+public class Robot
+{
+    public Guid Id { get; set; }
+    public string SerialNumber { get; set; }
+    public string Manufacturer { get; set; }
+    public RobotStatus Status { get; set; }
+    public double? CurrentX { get; set; }
+    public double? CurrentY { get; set; }
+    public double? BatteryLevel { get; set; }
+    public DateTime Created { get; set; }
+    public DateTime Modified { get; set; }
+}
+
+// 2. DbContext
+public class FleetDbContext : DbContext
+{
+    public DbSet<Robot> Robots { get; set; }
+    public DbSet<Mission> Missions { get; set; }
+
+    protected override void OnModelCreating(ModelBuilder modelBuilder)
+    {
+        modelBuilder.Entity<Robot>(entity =>
+        {
+            entity.HasKey(e => e.Id);
+            entity.HasIndex(e => e.SerialNumber).IsUnique();
+            entity.Property(e => e.SerialNumber).IsRequired().HasMaxLength(50);
+        });
+    }
+}
+
+// 3. Create migration
+// dotnet ef migrations add AddRobotEntity
+
+// 4. Apply migration
+// dotnet ef database update
+```

+# Appccelerate.StateMachine Usage Guide / Hướng dẫn Sử dụng Appccelerate.StateMachine
+
+## 📋 Overview / Tổng quan
+
+Tài liệu này mô tả cách sử dụng thư viện **Appccelerate.StateMachine** trong dự án RobotNet10. Thư viện này được sử dụng để quản lý state machine cho ScriptEngine (Task, Mission, và Engine Manager).
+
+## 📦 Installation / Cài đặt
+
+### NuGet Package
+
+```xml
+<PackageReference Include="Appccelerate.StateMachine" Version="6.0.0" />
+```
+
+### Namespaces
+
+```csharp
+using Appccelerate.StateMachine;
+using Appccelerate.StateMachine.Machine;
+```
+
+## 🎯 Core Concepts / Khái niệm Cơ bản
+
+### 1. States / Trạng thái
+
+States là các trạng thái mà state machine có thể ở trong. Thường được định nghĩa bằng enum:
+
+```csharp
+public enum TaskState
+{
+    Idle = 0,
+    Running,
+    Pausing,
+    Paused,
+    Resuming,
+    Stopping,
+    Stopped,
+    Error,
+}
+```
+
+### 2. Triggers / Sự kiện
+
+Triggers là các sự kiện có thể kích hoạt chuyển đổi trạng thái. Cũng thường là enum:
+
+```csharp
+public enum TaskTrigger
+{
+    Start,
+    Pause,
+    Resume,
+    Stop,
+    Dispose,
+    PausingCompleted,
+    ResumingCompleted,
+    StoppingCompleted,
+    ErrorOccurred,
+}
+```
+
+### 3. State Machine Types / Các Loại State Machine
+
+Appccelerate.StateMachine hỗ trợ hai loại state machine:
+
+- **PassiveStateMachine**: State machine được điều khiển thủ công, cần gọi `Fire()` để trigger transitions
+- **ActiveStateMachine**: State machine tự động xử lý events từ queue
+
+**Trong RobotNet10, chúng ta sử dụng `PassiveStateMachine`** để có kiểm soát tốt hơn.
+
+## 🏗️ Building State Machine / Xây dựng State Machine
+
+### Step 1: Create Builder / Tạo Builder
+
+```csharp
+var builder = new StateMachineDefinitionBuilder<TState, TTrigger>();
+```
+
+### Step 2: Configure States / Cấu hình States
+
+Sử dụng fluent API để cấu hình các states và transitions:
+
+```csharp
+builder.In(TaskState.Idle)
+    .On(TaskTrigger.Start)
+    .Goto(TaskState.Running)
+    .Execute(() => OnEnterRunning());
+```
+
+### Step 3: Configure Entry/Exit Actions / Cấu hình Entry/Exit Actions
+
+**Important**: `ExecuteOnEntry()` và `ExecuteOnExit()` phải được gọi **trước** các `On()` calls:
+
+```csharp
+builder.In(TaskState.Running)
+    .ExecuteOnEntry(() => { _currentState = TaskState.Running; OnEnterRunning(); })
+    .ExecuteOnExit(() => OnExitRunning())
+    .On(TaskTrigger.Pause)
+    .Goto(TaskState.Pausing)
+    .Execute(() => { _currentState = TaskState.Pausing; OnEnterPausing(); });
+```
+
+**⚠️ Common Mistake**: Đặt `ExecuteOnEntry()` sau `On()` sẽ gây lỗi compile.
+
+### Step 4: Build and Create / Build và Tạo
+
+```csharp
+var stateMachine = builder
+    .WithInitialState(TaskState.Idle)
+    .Build()
+    .CreatePassiveStateMachine();
+
+stateMachine.Start();
+```
+
+## 📝 Complete Example / Ví dụ Hoàn chỉnh
+
+Dựa trên implementation của `ScriptTask`:
+
+```csharp
+using Appccelerate.StateMachine;
+using Appccelerate.StateMachine.Machine;
+
+public class ScriptTask
+{
+    private readonly PassiveStateMachine<ScriptTaskState, TaskTrigger> _stateMachine;
+    private ScriptTaskState _currentState; // Track state manually
+

+        Start,
+        Pause,
+        Resume,
+        Stop,
+        Dispose,
+        PausingCompleted,
+        ResumingCompleted,
+        StoppingCompleted,
+        ErrorOccurred,
+    }
+
+    public ScriptTask()

+| `Fire(TTrigger trigger)` | Fire một trigger | `stateMachine.Fire(TaskTrigger.Start)` |
+| `Stop()` | Dừng state machine | `stateMachine.Stop()` |
+
+## ⚠️ Important Notes / Lưu Ý Quan trọng
+
+### 1. State Tracking / Theo dõi State
+
+**Problem**: `PassiveStateMachine` không có property `CurrentState` hoặc `CurrentStateId` để đọc state hiện tại.
+
+**Solution**: Sử dụng một field riêng để track state và update nó trong các transition handlers:
+
+```csharp
+private ScriptTaskState _currentState;
+
+// Update trong ExecuteOnEntry hoặc Execute
+builder.In(TaskState.Running)
+    .ExecuteOnEntry(() => { _currentState = TaskState.Running; OnEnterRunning(); });
+
+// Hoặc trong Execute của transition
+.On(TaskTrigger.Start)
+    .Goto(TaskState.Running)
+    .Execute(() => { _currentState = TaskState.Running; OnEnterRunning(); });
+```
+
+### 2. Entry/Exit Actions Order / Thứ tự Entry/Exit Actions
+
+**Critical**: `ExecuteOnEntry()` và `ExecuteOnExit()` **PHẢI** được gọi **TRƯỚC** các `On()` calls:
+
+```csharp
+// ✅ CORRECT
+builder.In(TaskState.Running)
+    .ExecuteOnEntry(() => OnEnterRunning())  // First
+    .ExecuteOnExit(() => OnExitRunning())   // Second
+    .On(TaskTrigger.Pause)                   // Then transitions
+    .Goto(TaskState.Pausing);
+
+// ❌ WRONG - Will cause compile error
+builder.In(TaskState.Running)
+    .On(TaskTrigger.Pause)
+    .Goto(TaskState.Pausing)
+    .ExecuteOnEntry(() => OnEnterRunning()); // Error!
+```
+
+### 3. State Machine Lifecycle / Vòng đời State Machine
+
+1. **Create**: Build definition và create state machine
+2. **Start**: Gọi `Start()` để khởi động (state machine sẽ ở initial state)
+3. **Fire Triggers**: Sử dụng `Fire()` để trigger transitions
+4. **Stop**: Gọi `Stop()` khi không cần dùng nữa
+
+```csharp
+var stateMachine = builder
+    .WithInitialState(TaskState.Idle)
+    .Build()
+    .CreatePassiveStateMachine();
+
+stateMachine.Start();  // State machine is now in Idle state
+
+// Later...
+stateMachine.Fire(TaskTrigger.Start);  // Transition to Running
+
+// When done...
+stateMachine.Stop();
+```
+
+### 4. Error Handling / Xử lý Lỗi
+
+State machine sẽ throw exception nếu:
+- Fire trigger không hợp lệ (không có transition từ state hiện tại)
+- State machine chưa được start
+- State machine đã được stop
+
+```csharp
+try
+{
+    _stateMachine.Fire(TaskTrigger.Start);
+}
+catch (Exception ex)
+{
+    _logger.LogError($"Failed to fire trigger: {ex.Message}");
+    throw;
+}
+```
+
+### 5. Thread Safety / An toàn Luồng
+
+`PassiveStateMachine` **không thread-safe**. Nếu cần thread safety, sử dụng lock:
+
+```csharp
+private readonly object _lockObject = new();
+
+public void Start()
+{
+    lock (_lockObject)
+    {
+        _stateMachine.Fire(TaskTrigger.Start);
+    }
+}
+```
+
+## 🎨 Best Practices / Thực hành Tốt nhất
+
+### 1. Separate Configuration Method / Tách Method Cấu hình
+
+Tách logic cấu hình state machine ra method riêng để code dễ đọc:
+
+```csharp
+private void ConfigureStateMachine(StateMachineDefinitionBuilder<TState, TTrigger> builder)
+{
+    // All configuration here
+}
+```
+
+### 2. Consistent State Tracking / Theo dõi State Nhất quán
+
+Luôn update `_currentState` trong cả `ExecuteOnEntry()` và `Execute()` của transitions để đảm bảo consistency:
+
+```csharp
+builder.In(TaskState.Running)
+    .ExecuteOnEntry(() => { _currentState = TaskState.Running; OnEnterRunning(); })
+    .On(TaskTrigger.Start)
+    .Goto(TaskState.Running)
+    .Execute(() => { _currentState = TaskState.Running; OnEnterRunning(); });
+```
+
+### 3. Use Descriptive Trigger Names / Sử dụng Tên Trigger Mô tả
+
+Đặt tên trigger rõ ràng để dễ hiểu:
+
+```csharp
+// ✅ Good
+TaskTrigger.PausingCompleted
+TaskTrigger.ResumingCompleted
+TaskTrigger.ErrorOccurred
+
+// ❌ Bad
+TaskTrigger.Done
+TaskTrigger.Ok
+TaskTrigger.Err
+```
+
+### 4. Document State Transitions / Tài liệu hóa State Transitions
+
+Sử dụng comments để giải thích logic:
+
+```csharp
+// Idle → Running: Start task
+builder.In(TaskState.Idle)
+    .On(TaskTrigger.Start)
+    .Goto(TaskState.Running);
+
+// Running → Pausing → Paused: Pause task (wait for current execution)
+builder.In(TaskState.Running)
+    .On(TaskTrigger.Pause)
+    .Goto(TaskState.Pausing);
+```
+
+## 🔄 State Transition Patterns / Mẫu Chuyển đổi State
+
+### Pattern 1: Simple Transition / Chuyển đổi Đơn giản
+
+```csharp
+builder.In(StateA)
+    .On(TriggerX)
+    .Goto(StateB)
+    .Execute(() => OnEnterStateB());
+```
+
+### Pattern 2: Transition with Entry/Exit / Chuyển đổi với Entry/Exit
+
+```csharp
+builder.In(StateA)
+    .ExecuteOnEntry(() => OnEnterStateA())
+    .ExecuteOnExit(() => OnExitStateA())
+    .On(TriggerX)
+    .Goto(StateB)
+    .Execute(() => OnEnterStateB());
+```
+
+### Pattern 3: Intermediate State / State Trung gian
+
+Sử dụng intermediate state cho async operations:
+
+```csharp
+// Start → Intermediate → Final
+builder.In(StateA)
+    .On(TriggerStart)
+    .Goto(StateIntermediate)
+    .Execute(() => StartAsyncOperation());
+
+builder.In(StateIntermediate)
+    .ExecuteOnEntry(() => OnEnterIntermediate())
+    .On(TriggerCompleted)
+    .Goto(StateFinal)
+    .Execute(() => OnEnterFinal());
+```
+
+## 🐛 Common Pitfalls / Lỗi Thường gặp
+
+### 1. Forgetting to Start / Quên Start
+
+```csharp
+// ❌ Wrong
+var stateMachine = builder.Build().CreatePassiveStateMachine();
+stateMachine.Fire(TaskTrigger.Start); // Exception!
+
+// ✅ Correct
+var stateMachine = builder.Build().CreatePassiveStateMachine();
+stateMachine.Start();
+stateMachine.Fire(TaskTrigger.Start);
+```
+
+### 2. Wrong Order of ExecuteOnEntry / Thứ tự ExecuteOnEntry Sai
+
+```csharp
+// ❌ Wrong - Compile error
+builder.In(StateA)
+    .On(TriggerX)
+    .Goto(StateB)
+    .ExecuteOnEntry(() => OnEnterStateB());
+
+// ✅ Correct
+builder.In(StateA)
+    .ExecuteOnEntry(() => OnEnterStateA())
+    .On(TriggerX)
+    .Goto(StateB)
+    .Execute(() => OnEnterStateB());
+```
+
+### 3. Not Tracking State / Không Theo dõi State
+
+```csharp
+// ❌ Wrong - No way to read current state
+public TaskState State => _stateMachine.CurrentState; // Property doesn't exist!
+
+// ✅ Correct
+private TaskState _currentState;
+public TaskState State => _currentState;
+
+// Update in transitions
+.Execute(() => { _currentState = TaskState.Running; OnEnterRunning(); });
+```
+
+### 4. Fire Invalid Trigger / Fire Trigger Không hợp lệ
+
+```csharp
+// ❌ Wrong - Will throw exception if no transition defined
+stateMachine.Fire(TaskTrigger.Start); // If current state doesn't allow Start
+
+// ✅ Correct - Check state first or handle exception
+if (_currentState == TaskState.Idle || _currentState == TaskState.Stopped)
+{
+    stateMachine.Fire(TaskTrigger.Start);
+}
+```

+
+## 📝 Naming Conventions / Quy ước Đặt tên
+
+### Namespaces
+
+**Pattern**: `RobotNet10.{ProjectName}[.{SubNamespace}]`
+
+**Examples**:
+```csharp
+namespace RobotNet10.Script;                    // Commons
+namespace RobotNet10.ScriptEngine.Shared;       // Shared

+public interface IRobotAppScriptGlobals { }
+public interface ILogger { }
+```
+
+**Classes**:
+```csharp
+// PascalCase, descriptive names
+public class ScriptEngine { }
+public class HubClient { }
+public class TaskAttribute : Attribute { }
+```
+
+**Abstract Classes**:

+```
+
+**Properties**:
+```csharp
+// PascalCase, noun-based names
+public IRobot Robot { get; }
+public bool IsConnected => Connection.State == HubConnectionState.Connected;
+public int Interval { get; }
+```
+
+**Async Methods**:
+- ✅ Always end with `Async` suffix
+- ✅ Return `Task` or `Task<T>`
+- ✅ Use `async/await` pattern
+
+**Rules**:
+- ✅ Use PascalCase
+- ✅ Methods: verb-based (e.g., `StartAsync`, `EnableTask`)
+- ✅ Properties: noun-based (e.g., `Robot`, `IsConnected`)
+- ✅ Async methods: suffix `Async`
+
+### Fields & Variables
+
+**Private Fields**:
+```csharp
+// camelCase with underscore prefix (if needed for clarity)
+private readonly HubConnection Connection;
+private readonly ManualResetEvent connectedWaitHandler;
+```
+
+**Local Variables**:
+```csharp
+// camelCase
+var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
+var app = builder.Build();
+```
+
+**Constants**:
+```csharp
+// PascalCase
+public const int DefaultInterval = 60;
+public const string DefaultConnectionString = "DefaultConnection";
+```
+
+**Rules**:
+- ✅ Private fields: camelCase (or underscore prefix if needed)
+- ✅ Local variables: camelCase
+- ✅ Constants: PascalCase
+
+### Attributes
+
+**Custom Attributes**:
+```csharp
+// End with 'Attribute', PascalCase
+[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = false)]
+public class TaskAttribute(int interval, bool autoStart = true) : Attribute
+{
+    public int Interval { get; } = interval;
+    public bool AutoStart { get; } = autoStart;
+}
+```
+
+**Usage**:
+```csharp
+[Task(interval: 60, autoStart: true)]
+public void MonitorTask() { }
+```
+
+### Project & File Names
+
+**Projects**:
+- ✅ Format: `RobotNet10.{Component}.{SubComponent}`
+- ✅ Examples: `RobotNet10.RobotApp`, `RobotNet10.FleetManager.Client`
+
+**Files**:
+- ✅ Match class/interface name (one class per file)
+- ✅ Use PascalCase: `HubClient.cs`, `TaskAttribute.cs`
+
+**Folders**:
+- ✅ Use PascalCase: `Components/`, `Clients/`, `Data/`
+
+## 🎯 Code Organization Principles / Nguyên tắc Tổ chức Code
+
+### 1. Separation of Concerns / Phân tách Trách nhiệm
+
+**Layers**:
+- **Presentation**: Blazor components và pages
+- **Application**: Business logic và services
+- **Data**: Database access (EF Core)
+- **Infrastructure**: External integrations (MQTT, hardware)
+
+### 2. Dependency Injection / Tiêm Phụ thuộc
+
+**Pattern**: Constructor injection
+
+```csharp
+public class OrderManager
+{
+    private readonly INavigationService _navigation;
+    private readonly ILogger<OrderManager> _logger;
+    
+    public OrderManager(INavigationService navigation, ILogger<OrderManager> logger)
+    {
+        _navigation = navigation;
+        _logger = logger;
+    }
+}
+```
+
+**Registration**:
+```csharp
+// In Program.cs
+builder.Services.AddScoped<IOrderManager, OrderManager>();
+builder.Services.AddSingleton<IRobotController, RobotController>();
+```
+
+### 3. Async/Await Pattern / Mẫu Async/Await
+
+**Always use async for I/O operations**:
+
+```csharp
+public async Task<bool> HandleOrderAsync(Order order)
+{
+    // Validate
+    if (!ValidateOrder(order))
+        return false;
+    
+    // Process (async)
+    await _navigation.MoveToNodeAsync(order.Nodes[0].NodeId);
+    
+    return true;
+}
+```
+
+**Rules**:
+- ✅ All I/O operations: async
+- ✅ Database queries: async
+- ✅ MQTT operations: async
+- ✅ HTTP requests: async
+- ✅ File operations: async
+
+### 4. Error Handling / Xử lý Lỗi
+
+**Pattern**: Structured exception handling
+
+```csharp
+try
+{
+    await ProcessOrderAsync(order);
+}
+catch (ValidationException ex)
+{
+    _logger.LogWarning(ex, "Order validation failed: OrderId={OrderId}", order.OrderId);
+    return false;
+}
+catch (Exception ex)
+{
+    _logger.LogError(ex, "Unexpected error processing order: OrderId={OrderId}", order.OrderId);
+    throw;
+}
+```
+
+### 5. Logging / Ghi Log
+
+**Pattern**: Structured logging với parameters
+
+```csharp
+_logger.LogInformation("Order received: OrderId={OrderId}, UpdateId={UpdateId}", 
+    order.OrderId, order.OrderUpdateId);
+
+_logger.LogWarning("Robot not available: SerialNumber={SerialNumber}", serialNumber);
+
+_logger.LogError(ex, "Failed to process order: OrderId={OrderId}", order.OrderId);
+```
+
+**Rules**:
+- ✅ Use structured logging (parameters, not string interpolation)
+- ✅ Appropriate log levels (Debug, Information, Warning, Error)
+- ✅ Include context (OrderId, SerialNumber, etc.)

+# Realtime Integration Guide / Hướng dẫn Tích hợp Realtime
+
+## 📋 Overview / Tổng quan
+
+Tài liệu này mô tả cách tích hợp tính năng Linux realtime (preempt_rt) vào ScriptTask và cách enable/disable tính năng này ở compile time.
+
+## 🔧 Enabling Realtime Support / Bật Hỗ trợ Realtime
+
+### Step 1: Uncomment DefineConstants / Bỏ comment DefineConstants
+
+Trong file `RobotNet10.ScriptEngine.csproj`, uncomment dòng sau:
+
+```xml
+<PropertyGroup>
+  <TargetFramework>net10.0</TargetFramework>
+  <ImplicitUsings>enable</ImplicitUsings>
+  <Nullable>enable</Nullable>
+  <!-- Define REALTIME symbol to enable Linux realtime features -->
+  <DefineConstants>$(DefineConstants);REALTIME</DefineConstants>
+</PropertyGroup>
+```
+
+### Step 2: Build Project / Build Dự án
+
+```bash
+dotnet build srcs/RobotNet10/Commons/RobotNet10.ScriptEngine/RobotNet10.ScriptEngine.csproj
+```
+
+Khi `REALTIME` symbol được define:
+- Code realtime sẽ được compile vào binary
+- ScriptTask sẽ sử dụng `RealtimeTimer` thay vì `System.Threading.Timer`
+- Có thể configure realtime scheduling policy và CPU affinity
+
+Khi `REALTIME` symbol **KHÔNG** được define:
+- Code realtime sẽ bị loại bỏ hoàn toàn (không compile)
+- ScriptTask sử dụng `System.Threading.Timer` (standard .NET timer)
+- Không có dependency vào Linux-specific APIs
+
+## 📝 Usage Examples / Ví dụ Sử dụng
+
+### Example 1: Basic Realtime Task / Task Realtime Cơ bản
+
+```csharp
+using RobotNet10.ScriptEngine.Models;
+using Microsoft.CodeAnalysis.Scripting;
+
+// Create ScriptTaskModel with compiled script runner
+var taskModel = new ScriptTaskModel(
+    name: "HighPriorityTask",
+    interval: 1, // 1 second
+    autoStart: true,
+    code: scriptCode,
+    runner: compiledScriptRunner
+);
+
+// Create ScriptGlobals with dictionaries
+var globals = new ScriptGlobals(
+    scriptRobotNet: robotNetGlobals,
+    scriptApp: appGlobals,
+    scriptVariables: variables,
+    scriptParameters: parameters
+);
+
+// Create task with realtime options
+var realtimeOptions = new RealtimeTaskOptions
+{
+    Enabled = true,
+    SetSchedulingPolicy = true,
+    SchedulingPolicy = RealtimeSchedulingPolicy.Fifo,
+    Priority = 50,
+    ClockType = RealtimeClockType.Monotonic
+};
+
+var task = new ScriptTask(
+    model: taskModel,
+    globals: globals,
+    realtimeOptions: realtimeOptions
+);
+```
+
+### Example 2: Task with CPU Affinity / Task với CPU Affinity
+
+```csharp
+var taskModel = new ScriptTaskModel(
+    name: "PinnedTask",
+    interval: 2,
+    autoStart: true,
+    code: scriptCode,
+    runner: compiledScriptRunner
+);
+
+var globals = new ScriptGlobals(
+    scriptRobotNet: robotNetGlobals,
+    scriptApp: appGlobals,
+    scriptVariables: variables,
+    scriptParameters: parameters
+);
+
+var realtimeOptions = new RealtimeTaskOptions
+{
+    Enabled = true,
+    SetSchedulingPolicy = true,
+    SchedulingPolicy = RealtimeSchedulingPolicy.Fifo,
+    Priority = 75,
+    CpuAffinity = new[] { 0, 1 }, // Pin to CPU 0 and 1
+    ClockType = RealtimeClockType.Monotonic
+};
+
+var task = new ScriptTask(
+    model: taskModel,
+    globals: globals,
+    realtimeOptions: realtimeOptions
+);
+```
+
+### Example 3: Disable Realtime for Specific Task / Tắt Realtime cho Task Cụ thể
+
+```csharp
+var taskModel = new ScriptTaskModel(
+    name: "StandardTask",
+    interval: 5,
+    autoStart: true,
+    code: scriptCode,
+    runner: compiledScriptRunner
+);
+
+var globals = new ScriptGlobals(
+    scriptRobotNet: robotNetGlobals,
+    scriptApp: appGlobals,
+    scriptVariables: variables,
+    scriptParameters: parameters
+);
+
+var realtimeOptions = new RealtimeTaskOptions
+{
+    Enabled = false // Use standard timer even if REALTIME is defined
+};
+
+var task = new ScriptTask(
+    model: taskModel,
+    globals: globals,
+    realtimeOptions: realtimeOptions
+);
+```
+
+### Example 4: Without Realtime Options / Không có Realtime Options
+
+```csharp
+var taskModel = new ScriptTaskModel(
+    name: "StandardTask",
+    interval: 10,
+    autoStart: true,
+    code: scriptCode,
+    runner: compiledScriptRunner
+);
+
+var globals = new ScriptGlobals(
+    scriptRobotNet: robotNetGlobals,
+    scriptApp: appGlobals,
+    scriptVariables: variables,
+    scriptParameters: parameters
+);
+
+// If realtimeOptions is null or not provided, uses standard timer
+var task = new ScriptTask(
+    model: taskModel,
+    globals: globals
+    // realtimeOptions: null (default)
+);
+```
+
+## ⚙️ RealtimeTaskOptions Configuration / Cấu hình RealtimeTaskOptions
+
+| Property | Type | Default | Description |
+|----------|------|---------|-------------|
+| `Enabled` | `bool` | `true` | Enable/disable realtime features for this task |
+| `SetSchedulingPolicy` | `bool` | `true` | Whether to set realtime scheduling policy |
+| `SchedulingPolicy` | `RealtimeSchedulingPolicy` | `Fifo` | SCHED_FIFO or SCHED_RR |
+| `Priority` | `int` | `50` | Priority (1-99, higher = higher priority) |
+| `CpuAffinity` | `int[]?` | `null` | CPU cores to pin thread to (null = no affinity) |
+| `ClockType` | `RealtimeClockType` | `Monotonic` | Clock type for timer (Monotonic recommended) |
+| `NonBlocking` | `bool` | `false` | **Note**: Always set to `true` internally for async monitoring |
+
+## 🎯 How It Works / Cách Hoạt động
+
+### Without REALTIME Symbol / Không có REALTIME Symbol
+
+```mermaid
+graph LR
+    A[ScriptTask.Start] --> B[System.Threading.Timer]
+    B --> C[ExecuteTask callback]
+    C --> D[Task execution]
+```
+
+### With REALTIME Symbol / Có REALTIME Symbol
+
+```mermaid
+graph LR
+    A[ScriptTask.Start] --> B{RealtimeOptions<br/>Enabled?}
+    B -->|Yes| C[RealtimeTimer<br/>timerfd]
+    B -->|No| D[System.Threading.Timer]
+    C --> E[Create Dedicated Thread<br/>Highest Priority]
+    E --> F[Set Scheduling Policy<br/>SCHED_FIFO/RR in thread]
+    E --> G[Set CPU Affinity<br/>in thread if configured]
+    E --> H[MonitorRealtimeTimer<br/>loop in thread]
+    H --> I[ReadExpirations<br/>non-blocking]
+    I --> J{Is Paused?}
+    J -->|No| K[ExecuteTask]
+    J -->|Yes| L[Skip Execution]
+    D --> K
+```
+
+## 🔑 Key Features / Tính năng Chính
+
+### 1. High-Resolution Timer / Timer Độ phân giải Cao
+
+- **RealtimeTimer**: Sử dụng Linux `timerfd` API
+- **Accuracy**: Nanosecond precision
+- **Better than**: `System.Threading.Timer` (millisecond precision)
+
+### 2. Dedicated Thread with Highest Priority / Thread Riêng với Độ Ưu tiên Cao nhất
+
+- **Dedicated Thread**: Tạo thread riêng cho realtime monitoring với `IsBackground = false`
+- **Thread Priority**: Set SCHED_FIFO/SCHED_RR với priority cao nhất trong thread
+- **Isolation**: Realtime monitoring chạy độc lập, không bị ảnh hưởng bởi các thread khác
+- **CPU Affinity**: Pin thread to specific CPU cores (nếu configured)
+- **Reduces cache misses**: Improves determinism
+
+### 3. Real-time Scheduling / Lập lịch Real-time
+
+- **SCHED_FIFO**: First-In-First-Out, highest priority threads run first
+- **SCHED_RR**: Round-Robin, time-sliced real-time scheduling
+- **Priority**: 1-99 (higher = higher priority)
+- **Applied in thread**: Scheduling policy được set trong dedicated thread, không ảnh hưởng main thread
+
+### 4. Pause/Resume Behavior / Hành vi Pause/Resume
+
+- **Timer continues**: Khi paused, timer/realtime loop vẫn tiếp tục chạy
+- **Skip execution**: Chỉ skip execution khi timer expire (check `_isPaused` flag)
+- **Instant resume**: Resume ngay lập tức không cần restart timer
+- **No interruption**: Timer không bị gián đoạn khi pause/resume
+
+### 5. ScriptTask Constructor / Constructor của ScriptTask
+
+- **ScriptTaskModel**: Nhận model chứa metadata và `ScriptRunner<object>`
+- **ScriptGlobals**: Nhận globals dictionary với ScriptRobotNet, ScriptApp, ScriptVariables, ScriptParameters
+- **Logger**: Tự động lấy từ `globals.ScriptRobotNet.TryGetValue("get_Logger", ...)`
+- **Execution**: Gọi `model.Runner(globals)` trực tiếp, không merge dictionaries
+
+### 6. Fallback Mechanism / Cơ chế Dự phòng
+
+- Nếu realtime initialization fails, falls back to standard timer
+- Logs error but continues operation
+- Ensures system reliability
+
+## ⚠️ Important Notes / Lưu Ý Quan trọng
+
+### 1. Root Privileges / Quyền Root
+
+Realtime scheduling requires root privileges or capabilities:
+
+```bash
+# Option 1: Run with sudo
+sudo dotnet run
+
+# Option 2: Set capabilities (recommended for production)
+sudo setcap cap_sys_nice+ep /path/to/your/app
+```
+
+### 2. Platform Specific / Phụ thuộc Nền tảng
+
+- **Only works on Linux**: Realtime features require Linux kernel
+- **preempt_rt recommended**: For best real-time performance
+- **Windows/macOS**: Code compiles but realtime features are disabled
+
+### 3. Performance Considerations / Xem xét Hiệu năng
+
+- **RealtimeTimer**: More accurate but requires Linux
+- **Standard Timer**: Cross-platform but less accurate
+- **Choose based on**: Target platform and accuracy requirements
+
+### 4. Error Handling / Xử lý Lỗi
+
+- Realtime initialization errors are caught and logged
+- System automatically falls back to standard timer
+- Task continues to function normally
+
+## 📊 Comparison / So sánh
+
+| Feature | Standard Timer | Realtime Timer |
+|---------|---------------|----------------|
+| **Platform** | Cross-platform | Linux only |
+| **Accuracy** | ~1ms | Nanosecond |
+| **Scheduling** | OS default | SCHED_FIFO/RR |
+| **CPU Affinity** | No | Yes |
+| **Root Required** | No | Yes (for scheduling) |
+| **Compile-time** | Always available | Requires REALTIME symbol |

+## 🔌 SignalR Integration
+
+### **Subscription Strategy**
+
+**Subscribe to All Robots (Broadcast từ Server)**
+- Get list of all robots from API
+- Subscribe to each robot individually
+- Handle add/remove robots dynamically
+- **Server broadcasts StateMsg và VisualizationMsg đến tất cả subscribed clients**
+
+**Implementation:**
+```csharp
+private async Task SubscribeToAllRobots()
+{
+    // Get all robots from API
+    var robots = await RobotApiService.GetAllAsync();
+    
+    foreach (var robot in robots)
+    {
+        await _hubClient.SubscribeToRobotAsync(robot.RobotId);
+    }
+}
+```
+
+### **Update Handling (Broadcast từ Server)**
+
+```csharp
+private void HandleStateUpdate(StateMsg state)
+{
+    var robotId = state.SerialNumber;
+    
+    // Get or create robot data
+    if (!Robots.TryGetValue(robotId, out var robotData))
+    {
+        // Load robot model image
+        robotData = new RobotMonitorData
+        {
+            RobotId = robotId,
+            ModelId = GetRobotModelId(robotId), // From RobotDto
+            ModelImageBase64 = await LoadRobotModelImage(robotId)
+        };
+        Robots[robotId] = robotData;
+    }
+    
+    // Update position and state
+    robotData.X = state.Pose?.X ?? 0;
+    robotData.Y = state.Pose?.Y ?? 0;
+    robotData.Theta = state.Pose?.Theta ?? 0;
+    robotData.LastState = state;
+    robotData.LastUpdateTime = DateTime.UtcNow;
+    
+    // Update path if ShowPath = true
+    if (ShowPath)
+    {
+        UpdateRobotPath(robotData);
+    }
+    
+    // If FollowRobot and this is selected robot, update viewport
+    if (FollowRobot && SelectedRobotId == robotId)
+    {
+        FocusOnRobot(robotId);
+    }
+    
+    NotifyStateChanged();
+}
+
+private void HandleVisualizationUpdate(VisualizationMsg visualization)
+{
+    var robotId = visualization.SerialNumber;
+    
+    if (Robots.TryGetValue(robotId, out var robotData))
+    {
+        robotData.LastVisualization = visualization;
+        robotData.LastUpdateTime = DateTime.UtcNow;
+        NotifyStateChanged();
+    }
+}
+```
+
+### **Robot Timeout (Remove Inactive Robots)**
+
+```csharp
+private void RemoveInactiveRobots()
+{
+    var timeout = TimeSpan.FromSeconds(10); // 10 seconds timeout
+    var now = DateTime.UtcNow;
+    
+    var inactiveRobots = Robots
+        .Where(kvp => now - kvp.Value.LastUpdateTime > timeout)
+        .Select(kvp => kvp.Key)
+        .ToList();
+    
+    foreach (var robotId in inactiveRobots)
+    {
+        Robots.Remove(robotId);
+        if (SelectedRobotId == robotId)
+        {
+            SelectedRobotId = null;
+        }
+    }
+    
+    if (inactiveRobots.Count > 0)
+    {
+        NotifyStateChanged();
+    }
+}
+```
+
+---
+
+## 🎯 Viewport Operations
+
+### **Zoom**
+- Similar to LayoutEditor
+- Zoom at cursor position (mouse wheel)
+- Zoom at center (toolbar buttons)
+- Limit zoom level (0.1x to 10x)
+
+### **Pan**
+- Middle mouse drag
+- Incremental delta (like LayoutEditor fix)
+
+### **FitToScreen**
+- Fit viewport to image bounds
+- Similar to LayoutEditor
+
+### **FocusOnRobot**
+- Center viewport on selected robot position
+- Optional: Zoom to fit robot (or keep current zoom)
+
+```csharp
+public void FocusOnRobot(string robotId)
+{
+    if (!Robots.TryGetValue(robotId, out var robot))
+        return;
+    
+    // Center viewport on robot
+    var (physicalWidth, physicalHeight) = GetPhysicalDimensions();
+    var svgX = WorldToSvg(robot.X, robot.Y).X;
+    var svgY = WorldToSvg(robot.X, robot.Y).Y;
+    
+    Viewport.ViewBoxX = svgX - Viewport.ViewBoxWidth / 2;
+    Viewport.ViewBoxY = svgY - Viewport.ViewBoxHeight / 2;
+    
+    NotifyStateChanged();
+}
+```
+
+---
+
+## 🖼️ Robot Image Rendering
+
+### **Image Loading**
+- Load robot model image when robot is first added
+- Cache images in state (Dictionary<Guid, string> for base64)
+- Load from API: `RobotModelApiService.GetImageAsync(modelId)`
+
+### **Image Positioning**
+- Position at (X, Y) from StateMsg
+- Convert world coordinates to SVG coordinates
+- Apply rotation by Theta (radians)
+
+### **Image Scaling**
+- Scale based on robot model dimensions (Length, Width)
+- Adjust for zoom level
+- Maintain aspect ratio
+
+### **SVG Implementation**
+```xml
+<g transform="translate(@svgX, @svgY) rotate(@degrees)">
+    <image href="data:image/png;base64,@robotData.ModelImageBase64"
+           x="@(-robotModel.Length/2)"
+           y="@(-robotModel.Width/2)"
+           width="@robotModel.Length"
+           height="@robotModel.Width"
+           preserveAspectRatio="xMidYMid" />
+</g>
+```
+
+---
+
+## 📝 Key Design Decisions
+
+### **1. Robot Data Management**
+- **Decision:** Store robot data in Dictionary<string, RobotMonitorData>
+- **Rationale:** Fast lookup by robotId, easy add/remove
+
+### **2. SignalR Subscription**
+- **Decision:** Subscribe to all robots individually, receive broadcast từ Server
+- **Rationale:** More control, can unsubscribe specific robots, Server broadcasts to all subscribed clients
+
+### **3. Robot Timeout**
+- **Decision:** Remove robots after 10 seconds of no updates
+- **Rationale:** Clean up inactive robots, avoid stale data
+
+### **4. Follow Robot**
+- **Decision:** Auto-update viewport when selected robot moves (if enabled)
+- **Rationale:** Better UX for tracking specific robot
+
+### **5. Path Visualization**
+- **Decision:** Store path as list of (X, Y) points
+- **Rationale:** Simple, can draw as polyline
+
+### **6. MudBlazor Components**
+- **Decision:** Use MudBlazor for all UI components
+- **Rationale:** Consistent with existing codebase, faster development
+
+### **7. Panel Expand/Collapse**
+- **Decision:** Button on toolbar to toggle RobotInfoPanel visibility
+- **Rationale:** More screen space for canvas when needed
+
+---
+

+
+## 📦 Module Structure
+
+### 1. RobotConnections Service
+
+**Trách nhiệm:**
+- Quản lý MQTT client connection (single instance)
+- Subscribe topics với wildcard pattern
+- Deserialize và route messages dựa trên SerialNumber
+- Publish orders và instantActions đến robots
+- Validate SerialNumber tồn tại trong database trước khi xử lý
+
+**MQTT Topics:**
+
+**Subscribe (wildcard):**
+- `uagv/v2/{Manufacturer}/+/state` (QoS 0, Retain: true)
+- `uagv/v2/{Manufacturer}/+/connection` (QoS 1, Retain: true)
+- `uagv/v2/{Manufacturer}/+/visualization` (QoS 0, Retain: false)
+- `uagv/v2/{Manufacturer}/+/factsheet` (QoS 0, Retain: true)
+
+**Publish:**
+- `uagv/v2/{Manufacturer}/{SerialNumber}/order` (QoS 1, Retain: false)
+- `uagv/v2/{Manufacturer}/{SerialNumber}/instantActions` (QoS 1, Retain: false)
+
+**Configuration (appsettings.json):**
+```json
+{
+  "VDA5050": {
+    "MqttBroker": {
+      "Host": "localhost",
+      "Port": 1883,
+      "Username": "",
+      "Password": "",
+      "EnablePassword": false,
+      "EnableTls": false,
+      "CaCertificatesPath": "",
+      "ClientCertificatePath": "",
+      "ClientKeyPath": ""
+    },
+    "Protocol": {
+      "Manufacturer": "RobotNet",
+      "Version": "2.1.0",
+      "TopicPrefix": "uagv/v2"
+    }
+  }
+}
+```
+
+**Interfaces:**
+```csharp
+public interface IRobotConnectionsService
+{
+    Task StartAsync(CancellationToken cancellationToken = default);
+    Task StopAsync(CancellationToken cancellationToken = default);
+    bool IsConnected();
+    Task<bool> PublishOrderAsync(string robotId, OrderMsg order, CancellationToken cancellationToken = default);
+    Task<bool> PublishInstantActionsAsync(string robotId, InstantActionsMsg instantActions, CancellationToken cancellationToken = default);
+}
+```
+
+### 2. RobotManager Service
+
+**Trách nhiệm:**
+- Quản lý `RobotController` instances (mỗi robot có 1 instance)
+- Subscribe events từ RobotConnectionsService qua Event Bus
+- Route events đến đúng RobotController instance và update RobotData
+- Auto-create RobotController khi nhận Connection/State message đầu tiên (sau khi validate có trong DB)
+- Timeout monitoring: Check mỗi 15s, nếu 30s không có State hoặc Visualization → set ConnectionState = OFFLINE
+- Remove RobotController khi robotId bị xóa khỏi DB
+
+**Data Structures (In-Memory):**
+```csharp
+// RobotController instances per robot
+ConcurrentDictionary<string, IRobotController> // Key: RobotId (SerialNumber)
+```
+
+**Timeout Monitoring:**
+- Sử dụng `WatchTimerAsync` từ RobotNet10.Common
+- Check interval: 15 giây
+- Timeout threshold: 30 giây không có State hoặc Visualization message
+- Reset timeout riêng biệt cho State và Visualization
+- Khi timeout: Set `ConnectionState = OFFLINE` trong RobotController.RobotData
+- Không cần retry/reconnect/event notification
+
+**RobotController Lifecycle:**
+- **Creation**: Tạo khi nhận Connection/State message đầu tiên và SerialNumber tồn tại trong DB
+- **Deletion**: Xóa khi robotId bị xóa khỏi DB (service xóa robot sẽ inject RobotManagerService và gọi `RemoveRobotController(robotId)`)
+- **Dispose**: RobotController implement IDisposable để cleanup resources
+
+**Interfaces:**
+```csharp
+public interface IRobotManagerService
+{
+    // RobotController Management
+    IRobotController? GetRobotController(string robotId);
+    IReadOnlyDictionary<string, IRobotController> GetAllRobotControllers();
+    void RemoveRobotController(string robotId);
+    
+    // Backward compatibility (delegate to RobotController)
+    RobotData? GetRobotData(string robotId);
+    IReadOnlyDictionary<string, RobotData> GetAllRobotData();
+    IReadOnlyList<string> GetAvailableRobots(); // Robots với IsOnline == true
+}
+```
+
+### 3. RobotController (Instance per Robot)
+
+**Trách nhiệm:**
+- Mô hình hóa thông tin của 1 robot, định danh bằng RobotId (SerialNumber)
+- Không phải service, mà là instance với mỗi robot
+- Chứa thông tin robot gửi lên (RobotData)
+- Chứa các functions để xử lý và publish xuống robot
+- Thread-safe với lock cho các methods gửi order/instantAction
+
+**Properties:**
+```csharp
+public interface IRobotController : IDisposable
+{
+    string RobotId { get; }              // SerialNumber
+    RobotData RobotData { get; }         // Tất cả thông tin robot
+    bool IsOnline { get; }               // Derived từ ConnectionState
+}
+```
+
+**Methods (Thread-safe với lock):**
+```csharp
+public interface IRobotController
+{
+    // Robot Control
+    Task<bool> MoveToNodeAsync(string nodeName, CancellationToken cancellationToken = default);
+    Task<bool> SendInstantActionAsync(Action action, CancellationToken cancellationToken = default);
+    Task<bool> SendOrderAsync(OrderMsg order, CancellationToken cancellationToken = default);
+    Task<bool> SendInstantActionsAsync(InstantActionsMsg instantActions, CancellationToken cancellationToken = default);
+    Task<bool> RequestFactsheetAsync(CancellationToken cancellationToken = default);
+    Task<bool> RequestStateAsync(CancellationToken cancellationToken = default);
+    Task<bool> CancelOrderAsync(CancellationToken cancellationToken = default);
+}
+```
+
+**Dependencies (Injected):**
+- `IRobotConnectionsService` - Để publish messages
+- `IConfigManager` - Để lấy VDA5050 config (Manufacturer, Version)
+- `Logger<RobotController>` - Để logging
+- `IRobotManagerService` - (Optional) Để tự xóa khi cần
+
+**MoveToNode Implementation:**
+- Implement cơ bản: Tạo OrderMsg đơn giản với 1 node (target node)
+- Có thể inject `ITrafficControlService` sau để tính route phức tạp hơn
+- Sẽ được implement trong cuộc hội thoại khác
+
+**Thread-Safety:**
+- Lock các methods có thể gửi order hoặc instantAction xuống robot
+- Không cần lock RobotData (read-only access từ bên ngoài)
+- RobotManagerService update RobotData trực tiếp (thread-safe dictionary)
+
+### 4. Event Bus System
+
+**Trách nhiệm:**
+- In-memory event system để communication giữa modules
+- Decouple RobotConnections và RobotManager
+- Sử dụng C# event pattern
+
+**Events:**
+```csharp
+public interface IRobotEventBus
+{
+    event EventHandler<StateMessageReceivedEvent>? StateMessageReceived;
+    event EventHandler<ConnectionStateChangedEvent>? ConnectionStateChanged;
+    event EventHandler<VisualizationMessageReceivedEvent>? VisualizationMessageReceived;
+    event EventHandler<FactsheetMessageReceivedEvent>? FactsheetMessageReceived;
+    
+    void PublishStateMessageReceived(string robotId, StateMsg stateMsg);
+    void PublishConnectionStateChanged(string robotId, ConnectionState connectionState);
+    void PublishVisualizationMessageReceived(string robotId, Visualizationmsg visualizationMsg);
+    void PublishFactsheetMessageReceived(string robotId, FactSheetMsg factsheetMsg);
+}
+```
+
+**Event Classes:**
+- `StateMessageReceivedEvent` - Khi nhận state message từ robot
+- `ConnectionStateChangedEvent` - Khi connection state thay đổi
+- `VisualizationMessageReceivedEvent` - Khi nhận visualization message
+- `FactsheetMessageReceivedEvent` - Khi nhận factsheet message
+
+### 5. SignalR Hub
+
+**Trách nhiệm:**
+- Broadcast real-time updates đến WebUI clients
+- Support per-robot subscriptions
+- Broadcast tất cả state changes
+
+**Hub Methods:**
+- `SubscribeToRobot(string robotId)` - Subscribe updates cho 1 robot
+- `UnsubscribeFromRobot(string robotId)` - Unsubscribe
+
+**Broadcast:**
+- Broadcast tất cả state changes đến tất cả clients
+- Group: `robot:{robotId}` cho subscription per robot
+
+## 🔄 Data Flow
+
+### State Message Flow
+```
+Robot → MQTT Broker → RobotConnectionsService
+    → Deserialize & Validate SerialNumber exists in DB
+    → Publish StateMessageReceivedEvent via Event Bus
+    → RobotManagerService receives event
+    → Tìm RobotController instance theo RobotId
+    → Update RobotData.State vào RobotController
+    → Determine OrderStatus từ State message
+    → Broadcast via SignalR Hub
+    → WebUI Clients receive update
+```
+
+### Order Flow
+```
+ScriptEngine/WebUI → RobotManagerService.GetRobotController(robotId)
+    → robotController.MoveToNode("NodeA")
+    → RobotController tính toán route (cơ bản)
+    → Tạo OrderMsg
+    → RobotConnectionsService.PublishOrderAsync()
+    → MQTT Broker → Robot
+    → Robot processes order
+    → Robot sends State message with orderId/orderUpdateId
+    → RobotManagerService updates RobotData vào RobotController
+    → Determine OrderStatus (Accepted, Completed, etc.)
+```
+
+### Connection State Flow
+```
+Robot → MQTT Broker (connection message)
+    → RobotConnectionsService
+    → Publish ConnectionStateChangedEvent
+    → RobotManagerService receives event
+    → Tìm hoặc tạo RobotController instance
+    → Update RobotData.ConnectionState vào RobotController
+    → SignalR broadcasts update
+```
+
+### RobotController Creation Flow
+```
+Robot → MQTT Broker (connection/state message)
+    → RobotConnectionsService
+    → Validate SerialNumber exists in DB
+    → Publish event via Event Bus
+    → RobotManagerService receives event
+    → Check if RobotController exists
+    → If not exists: Create new RobotController instance
+    → Inject dependencies (IRobotConnectionsService, IConfigManager, Logger)
+    → Add to ConcurrentDictionary<string, IRobotController>
+    → Update RobotData vào RobotController
+```
+
+## 📊 Data Models
+
+### RobotData
+```csharp
+public class RobotData
+{
+    public string RobotId { get; set; }              // SerialNumber
+    public StateMsg? State { get; set; }              // Latest State message
+    public ConnectionState ConnectionState { get; set; }
+    public OrderMsg? Order { get; set; }              // Latest Order message
+    public OrderStatus OrderStatus { get; set; }      // Order status tracking
+    public FactSheetMsg? Factsheet { get; set; }      // Latest Factsheet
+    public VisualizationMsg? Visualization { get; set; } // Latest Visualization
+    public DateTime LastUpdated { get; set; }         // Last update timestamp
+}
+```
+
+### OrderStatus
+```csharp
+public enum OrderStatus
+{
+    Pending,      // Order đã tạo nhưng chưa gửi
+    Sent,         // Order đã gửi qua MQTT
+    Accepted,     // Robot đã accept order (orderId và orderUpdateId khớp)
+    Rejected,     // Robot reject order (error với errorReferences)
+    Completed,    // Order hoàn thành (nodeStates và edgeStates empty)
+    Failed        // Order failed (FATAL error liên quan đến order)
+}
+```
+
+**Order Status Determination Logic:**
+- **Accepted**: `orderId` và `orderUpdateId` trong state khớp với order đã gửi
+- **Rejected (Error)**: Có error với `errorReferences` chứa `orderId` hoặc `orderUpdateId` → Log và hủy order (không retry)
+- **Completed**: `nodeStates` và `edgeStates` empty, `orderId` khác rỗng
+- **Failed**: Có error FATAL liên quan đến order
+
+## 🔍 Robot Discovery
+
+**Auto-Discovery:**
+- Khi nhận connection/state message với SerialNumber
+- Kiểm tra SerialNumber có trong database không (qua IRobotService)
+- Nếu không có → Bỏ qua message (không tự động tạo robot)
+- Nếu có → Xử lý message và update state
+
+**Mapping:**
+- `SerialNumber` (từ VDA5050) = `RobotId` (trong database)
+
+## ⚙️ Configuration
+
+### MQTT Configuration
+- Lưu trong `appsettings.json` section `VDA5050`
+- Bao gồm: Host, Port, Username, Password, TLS settings, Manufacturer, Version, TopicPrefix
+
+### Service Registration
+- `IRobotConnectionsService` → Singleton
+- `IRobotManagerService` → Singleton
+- `IRobotEventBus` → Singleton
+- `RobotController` instances → Managed by RobotManagerService (không register trong DI)
+
+## 🔄 Retry Logic
+
+**Order Rejection Handling:**
+- **Reject do Error**: Log và hủy order (không retry)
+- **Reject do Connection/Timeout**: Retry với exponential backoff
+- Retry cho đến khi có hành động hủy bỏ
+
+## 📡 Factsheet Handling
+
+- Subscribe factsheet topic với wildcard
+- Lưu factsheet per robot khi nhận được
+- Có thể request factsheet bằng instant action `factsheetRequest`
+- Factsheet được retain trên MQTT broker
+
+## 🎯 Performance Considerations
+
+**Với 203 robots:**
+- State messages: ~1,015 messages/second (5 Hz per robot)
+- Visualization: ~406 messages/second (2 Hz per robot)
+- Total inbound: ~1,500 messages/second
+- Estimated CPU: ~2.25 cores for message processing
+- Memory: ~1-2 GB (in-memory state + overhead)
+
+**Optimization:**
+- In-memory storage (no database writes for state)
+- Single MQTT client (no connection pool needed)
+- Event-driven architecture (async processing)
+
+## 🔐 Security Considerations
+
+- MQTT TLS support (optional)
+- Certificate-based authentication (optional)
+- SerialNumber validation (must exist in database)
+- No auto-creation of robots from messages
+
+## 📝 Notes
+
+- **Single Instance**: FleetManager chạy single instance (không cần HA)
+- **In-Memory Queue**: Sử dụng Channel<T> cho async processing nếu cần
+- **No History**: Chỉ lưu state/order/action mới nhất (không lưu history)
+- **RobotController**: Instance per robot, không phải service
+- **MoveToNode**: Implement cơ bản (tạo order đơn giản), có thể enhance với TrafficControl sau
+- **Timeout Monitoring**: 30s không có State hoặc Visualization → OFFLINE
+
+## 🔗 Dependencies
+
+- `RobotNet.VDA5050` - VDA5050 message models (qua RobotNet10.Common)
+- `RobotNet10.Common` - Common utilities (WatchTimerAsync, MQTTClient, etc.)
+- `Microsoft.AspNetCore.SignalR` - SignalR for real-time updates

+
+## 📡 VDA 5050 Protocol Handler
+
+**Mục đích**: Xử lý giao tiếp VDA 5050 với các robot (không phải module riêng, mà là phần của RobotManager và RobotConnections).
+
+**Chức năng**:
+- **Order Generation**: Tạo VDA 5050 orders từ TrafficControl
+- **Order Updates**: Tạo OrderUpdate (cùng orderId, orderUpdateId tăng) khi TrafficControl yêu cầu
+- **State Processing**: Xử lý state messages từ robots (chỉ quản lý state hiện tại, không lưu history)
+- **Action Generation**: Tạo instant actions (stopPause, cancelOrder, etc.)
+- **Message Validation**: Validate VDA 5050 messages

+
+## 🎯 Design Principles / Nguyên tắc Thiết kế
+
+### 1. Scalability / Khả năng Mở rộng
+
+**Mục tiêu**: Hỗ trợ 100+ robot đồng thời
+
+**Thiết kế**:
+- Stateless service design (không lưu state trong memory)
+- Asynchronous processing (async/await)
+- Efficient database queries (indexes, pagination)
+- MQTT broker clustering support (nếu cần)
+
+### 2. Reliability / Độ Tin cậy
+
+**Mục tiêu**: Hệ thống không được gián đoạn
+
+**Thiết kế**:
+- MQTT QoS levels phù hợp (QoS 1 cho orders)
+- Auto-reconnection logic
+- Graceful degradation (degraded mode khi có lỗi)
+- Comprehensive error handling
+- Safety monitoring (emergency stop < 50ms)
+
+### 3. Real-time Performance / Hiệu năng Real-time
+
+**Yêu cầu**:
+- State processing: < 50ms per robot state
+- Order generation: < 100ms
+- Conflict detection: < 500ms
+- Dashboard update: < 100ms (via SignalR)
+
+**Thiết kế**:
+- SignalR for real-time updates
+- Efficient state processing pipeline
+- Background workers for heavy tasks
+- Caching frequently accessed data
+
+### 4. Interoperability / Khả năng Tương tác
+
+**Mục tiêu**: Tương thích với hệ thống bên thứ 3
+
+**Thiết kế**:
+- Tuân thủ nghiêm ngặt VDA 5050 v2.1.0 (tương thích ngược với v2.0.0)
+- Standard MQTT protocol
+- REST API for external integration (planned)
+- JSON message format (camelCase)
+

+
+## 📈 Performance Requirements / Yêu cầu Hiệu năng
+
+| Chỉ số | Mục tiêu | Ghi chú |
+|--------|----------|---------|
+| **Max Robots** | 100+ | Per FleetManager instance |
+| **State Processing** | < 50ms | Per robot state message |
+| **Order Generation** | < 100ms | From mission to VDA 5050 order |
+| **Conflict Detection** | < 500ms | Multi-robot conflict check |
+| **Route Optimization** | < 2 seconds | A* pathfinding |
+| **Dashboard Update** | < 100ms | Via SignalR real-time |
+| **Database Query** | < 200ms | Average response time |
+
+## 🔌 ScriptEngine Integration / Tích hợp ScriptEngine
+
+**Mục đích**: Cho phép tùy chỉnh logic mission planning và tích hợp hệ thống bên ngoài.
+
+**FleetManager Script APIs**:
+
+ScriptEngine trong FleetManager expose các APIs thông qua `FleetScriptGlobals`:
+
+```csharp
+// Robot Management
+Robot GetRobotById(string robotId);
+Robot GetRobotBySerial(string serialNumber);
+List<Robot> GetAvailableRobots();
+
+// Order Creation (tự động tìm route và tạo order)
+Task MoveToNode(string robotSerial, string nodeId);
+Task MoveToStation(string robotSerial, string stationId);
+
+// Robot State
+RobotState GetRobotState(string robotSerial);
+
+// External System Integration
+// Có thể khai báo kết nối với:
+// - HTTP APIs
+// - Modbus TCP
+// - OPC UA
+// - CcLink
+// - ProfileNet
+// - MQTT (external)
+```
+
+**Mission và Task trong FleetManager**:
+
+- **Mission**: Methods có `[Mission]` attribute trong script, được ScriptEngine extract và tạo thành MissionInstance
+- **Task**: Methods có `[Task]` attribute, chạy lặp lại theo interval
+- Mission và Task có thể tương tác qua common APIs:
+  - `EnableTask(string taskName)` / `DisableTask(string taskName)`
+  - `CreateMission(string missionName, params)` / `CancelMission(Guid missionId)`
+
+**Luồng Mission Execution**:
+
+```mermaid
+sequenceDiagram
+    participant Script as C# Script
+    participant ScriptEngine
+    participant MissionInstance
+    participant FleetAPI as FleetManager APIs
+    participant RouteSvc as Route Service
+    participant VDAHandler as VDA Handler
+    participant Robot
+    
+    Script->>ScriptEngine: [Mission] method defined
+    ScriptEngine->>ScriptEngine: Extract & compile
+    ScriptEngine->>MissionInstance: Create MissionInstance
+    MissionInstance->>FleetAPI: MoveToNode("ROBOT001", "NodeA")
+    FleetAPI->>RouteSvc: Find route to NodeA
+    RouteSvc->>VDAHandler: Generate VDA 5050 Order
+    VDAHandler->>Robot: Send Order
+    Robot->>FleetAPI: State updates
+    FleetAPI->>MissionInstance: Continue execution
+```
+
+## 🚀 Deployment Architecture / Kiến trúc Triển khai
+
+**Deployment Model**:
+- **Single Instance**: FleetManager chạy một instance duy nhất, có thể điều phối nhiều robot (100+)
+- **Không hỗ trợ multiple instances**: FleetManager không chạy multiple instances để share workload
+
+**Infrastructure**:
+
+```mermaid
+graph TB
+    subgraph "FleetManager Server"

+
+### 4.2 RF Handle → RobotController → StateMachine
+
+```
+RF Handle Mode Changes (detected in ManualControlService.UpdateFromDeviceLoop):
+
+ManualControlService.HandleRfModeChange():
+    Detects RF Mode change → raises OnRfModeChanged event (does NOT fire StateMachine directly)
+
+ManualControlService disconnect detection:
+    RF Handle loses connection (RemoteReady=false) → fires OnRfModeChanged(RFMode.None)
+    → RobotController releases RF priority and transitions to PLC mode
+
+ManualControlService EStop handling:
+    RF Handle EStop pressed → ManualControlService enters SafeStop internally (stops robot)
+    → Does NOT clear _externallySetState → StateMachine stays in Service/Remote_Override
+    → When EStop released → ManualControlService recovers to Maintenance/Override automatically
+
+RobotController.OnRfModeChanged(rfMode):
+    RFMode.Maintenance  → _rfHandleHasPriority=true → Pause if in Auto → Fire(EnterService)
+    RFMode.Override     → _rfHandleHasPriority=true → Pause if in Auto → Fire(RemoteOverride)
+    RFMode.Default/None → _rfHandleHasPriority=false → SwichModeChanged(PlcController.PeripheralMode)
+                           (returns to PLC-determined mode: Auto with resume, Manual, etc.)
+
+ModeSelect Button Hold (2 seconds):
+    Active state     + hold 2s → PlcController.SetRFMode(Maintenance)
+    Maintenance state + hold 2s → PlcController.SetRFMode(Override)
+    → PLC changes → RF reads new mode → OnRfModeChanged → RobotController handles transition
+```
+
+> **Design**: All state transitions go through `RobotController` to ensure Pause/Resume and PLC sync.
+> `ManualControlService` never fires `RobotStateMachine` directly.
+
+### 4.4 RF Handle Priority & Thread Safety
+
+```
+_rfHandleHasPriority flag (in RobotController):
+    Set to true  when OnRfModeChanged(Maintenance/Override)
+    Set to false when OnRfModeChanged(Default/None) or RF Handle disconnect
+
+Protection:
+    - OnPlcModeChanged: checks _rfHandleHasPriority → ignores PLC switch changes when RF active
+    - WatchThread mode mismatch: skipped when _rfHandleHasPriority (backup stop still runs)
+
+_stateTransitionLock (in RobotController):
+    All state transition methods use lock(_stateTransitionLock):
+    - OnPlcModeChanged, OnRfModeChanged, OnStop, OnButtonPressed, OnNewFatalError, WatchThreadCallback
+    → Prevents race conditions between PLC Modbus thread, RF Handle 20Hz thread, WatchThread 5Hz
+
+ClearExternalState (in ManualControlService):
+    Called from ExitService/ExitRemoteOverride → resets _previousRfMode=None
+    → Next UpdateFromDeviceLoop cycle detects current RF mode as "changed"
+    → Fires OnRfModeChanged → RobotController re-enters Service/Remote_Override if RF still active
+```

+```
+
+---
+
+## 5. Order Execution Flow
+
+### 5.1 RobotOrderController (IOrder)
+
+Timer-based execution engine running at 100ms intervals.
+
+```
+UpdateOrder(OrderMsg) ─┬─ [first time] → HandleOrderStart() → Timer(100ms, OrderHandler)
+                       └─ [update] → lock(NewOrder = order)
+
+OrderHandler() every 100ms:
+    1. If NewOrder exists:
+       - New order ID → HandleNewOrder():
+           a. ClearOldOrder()
+           b. ValidateNodes() → check sequence IDs, collect actions per node
+           c. ValidateEdges() → check startNode/endNode, build trajectory
+           d. ActionManager.AddOrderActions(collected actions)
+           e. If single-node with actions → NavigationFinished(Completed), Fire(StartACT)
+       - Same order ID, higher updateId → HandleUpdateOrder():
+           a. Merge new nodes/edges with existing base
+           b. Same validation logic
+
+    2. If HasNewOrder (after validation):
+       - First node has actions? → StartActionTerminal() (run actions first)
+       - No actions? → NavigationManager.Move(Nodes, Edges)
+                     → Fire(StartExecution) if not already Executing
+                     → Subscribe OnNavigationFinished, OnSafetySpeedChanged
+
+    3. If IsCancelOrder → NavigationManager.CancelMovement()
+
+    4. If IsNavigationFinished:
+       - Canceled → HandleOrderStop()
+       - Completed → run terminal actions on last node, then HandleOrderStop()
+       - Error → HandleOrderStop()
+
+    5. Track current node position:
+       - GetCurrentNode() checks robot distance to each node
+       - When arriving at node → update LastNode, ClearLastNode()
+       - If node has SOFT/HARD actions → Pause navigation, enqueue actions
+       - Run actions sequentially (HARD blocks until done)
+       - All actions done → Resume navigation
+
+HandleOrderStop():
+    - Dispose timer
+    - Clear all order data
+    - Unsubscribe events
+    - Fire(CompleteExecution) → Executing → Idle
+```
+
+### 5.2 Action Blocking Types During Navigation
+
+| BlockingType | Behavior |
+|---|---|
+| `NONE` | Action runs in parallel, navigation continues |
+| `SOFT` | Navigation pauses at node, all SOFT+HARD actions enqueued, navigation resumes after all done |
+| `HARD` | Same as SOFT but each HARD action must complete before next action starts |
+
+---
+
+## 6. Action System
+
+### 6.1 RobotAction Base Class
+
+Each action has its own internal state machine:
+
+```
+WAITING ──► INITIALIZING ──► RUNNING ──► FINISHED
+   │              │              │
+   └──► FAILED    └──► FAILED   └──► FAILED
+   │              │              │
+   └──► PAUSED    └──► PAUSED   └──► PAUSED ──► WAITING (resume)
+```
+
+**Lifecycle:**
+1. `RobotActionProvider.GetRobotAction(type)` creates instance via `ActivatorUtilities`
+2. `Initialize(scope, action)` validates ActionType, BlockingType, ActionScope, parameters
+3. `Start()` → timer 200ms → `ActionHandler()` loop:
+   - `INITIALIZING` → calls `StartAction()`
+   - `RUNNING` → calls `ExecuteAction()` repeatedly
+   - `PAUSED` → calls `PauseAction()`
+   - Cancel requested → calls `StopAction()`
+4. When `IsCompleted` (FINISHED or FAILED) → `DisposeAsync()`
+
+### 6.2 Action Discovery
+
+`RobotActionProvider` scans all assemblies starting with "RobotNet10.RobotApp" for classes:
+- Inheriting `RobotAction`
+- Having `[RobotActionAttribute]`
+- Maps `ActionType → Type` for factory creation
+
+### 6.3 Available Actions
+
+| ActionType | Class | Scope | Blocking | Implementation Status |
+|---|---|---|---|---|
+| `CANCEL_ORDER` | `RobotCancelOrderAction` | INSTANT | ALL | Implemented - calls StopOrder() + StopOrderAction(), polls until cleared |

+| `MOVE_STRAIGHT_WITH_DISTANCE` | `RobotMoveStraightWithDistanceAction` | INSTANT | HARD | Not implemented |
+| `SCRIPT` | `RobotScriptAction` | ALL | ALL | Not implemented (has bug in Initialize: `!string.IsNullOrEmpty` should be `string.IsNullOrEmpty`) |
+| `INIT_POSITION` | `RobotInitPositionAction` | INSTANT | HARD | (needs verification) |
+| `STATE_REQUEST` | `RobotStateRequestAction` | INSTANT | ALL | (needs verification) |
+| `FACTSHEET_REQUEST` | `RobotFactsheetRequestAction` | INSTANT | ALL | (needs verification) |

+| `MUTED_LOAD_ON/OFF` | `RobotMutedLoadOnAction/OffAction` | INSTANT | ALL | (needs verification) |

+
+## 7. SystemState (PLC Level)
+
+The PLC has its own state representation written via Modbus coils.
+
+```csharp
+public enum SystemState { INIT, PAUSED, IDLE, PROCCESSING, DOCKING, MAINTENANCE, MANUAL, OVERRIDE, CHARGING, ERROR }
+```
+
+### Mapping: RobotStateMachine → PLC SystemState
+
+Set directly in each Entry handler of `RobotStateMachineExecute` via `PlcController.SetSystemState()`.
+
+| Robot State | SystemState | Notes |
+|---|---|---|
+| `Initializing` | `INIT` | Set directly in ModuleInitializeAsync() |
+| `Standby` | `IDLE` | |
+| `Idle` | `IDLE` | |
+| `Moving` | `PROCCESSING` | |
+| `Loading` / `Unloading` / `TechAction` | `PROCCESSING` | |
+| `Stop` | `PAUSED` | |
+| `Manual` | `MANUAL` | |
+| `Service` | `MAINTENANCE` | |
+| `Fault` | `ERROR` | |
+| `Docking` / `Docked` / `Undocking` | `DOCKING` | |
+| `Charging` | `CHARGING` | |
+| `Remote_Override` | `OVERRIDE` | |
+
+---
+
+## 8. ManualControlService State Machine
+
+Separate from RobotStateMachine. Runs on dedicated high-priority thread at configurable UpdateRate (e.g., 20Hz).
+
+```csharp
+public enum ManualControlState
+{
+    Initialization,  // RF Handle not connected
+    Disabled,        // RemoteReady == false (no signal)
+    SafeStop,        // EStop pressed
+    Active,          // Has signal + no EStop, waiting for RobotStateMachine to set mode
+    Maintenance,     // Allows robot control (set by RobotStateMachine via EntryService)
+    Override,        // Full override control (set by RobotStateMachine via EntryRemoteOverride)
+    Default          // Reserved
+}
+```
+
+### State Determination Priority (every cycle)
+
+1. RF Handle not connected → `Initialization`
+2. `RemoteReady == false` → `Disabled` (resets external state)
+3. `EStop == true` → `SafeStop` (resets external state)
+4. External state set (by RobotStateMachine) → use that state (`Maintenance` or `Override`)
+5. Otherwise → `Active`
+
+### Bidirectional Interaction with RobotStateMachine
+
+```
+RobotStateMachine ──EntryService()──► ManualControlService.SetState(Maintenance)
+RobotStateMachine ──ExitService()──► ManualControlService.ClearExternalState()
+RobotStateMachine ──EntryRemoteOverride()──► ManualControlService.SetState(Override)
+RobotStateMachine ──ExitRemoteOverride()──► ManualControlService.ClearExternalState()
+
+ManualControlService ──HandleRfModeChange()──► RobotStateMachine.Fire(EnterService/RemoteOverride/EnterAuto)
+```
+
+### Control Actions (only in Maintenance/Override/Active states)
+
+- **Velocity**: RF Handle Forward/Backward → linear, Left/Right → angular
+- **Lift**: RF Handle LiftUp/LiftDown → ILiftModule.LiftUpAsync/LiftDownAsync
+- **Rotation**: RF Handle RotateLeft/RotateRight → IRotationModule.RotateOffsetAsync(+/-90)
+- Speed controlled by RF Handle Speed potentiometer (0-100%)

+## 9. VDA5050 State Publishing
+
+`RobotStates` (IState) publishes `StateMsg` every 1 second via MQTT:
+
+```csharp
+StateMsg includes:
+    - HeaderId, Manufacturer, Version, SerialNumber
+    - OrderId, OrderUpdateId, ZoneSetId
+    - LastNodeId, LastNodeSequenceId
+    - Driving (based on velocity > 0)

+
+## 11. WatchThread (5Hz Background Monitor)
+
+`RobotController` starts a `WatchTimer<RobotController>` at 200ms (5Hz) after initialization. All operations run inside `lock(_stateTransitionLock)`. Responsibilities:
+
+1. **Fatal error detection**: Checks `ErrorManager.HasFatalError` → if true and not in Fault → `Pause()` + `Fire(EnterFault)`.
+   Also triggered reactively by `ErrorManager.OnNewFatalError` event.
+
+2. **PLC mode backup sync**: Detects missed `OnPeripheralModeChanged` events:
+   - If in `Standby` (after ReleaseStop or init) → calls `SwichModeChanged(plcMode)` to enter correct mode
+   - If PLC mode doesn't match current state → calls `SwichModeChanged(plcMode)` to correct
+   - **Skipped when `_rfHandleHasPriority`** — RF Handle mode takes precedence over PLC switch
+
+3. **Backup stop detection**: Reads PLC safety properties (`Emergency`, `Bumper`) directly. If any active and not in Stop → enters Stop state. **Always runs, even when RF Handle has priority** — safety overrides everything.
+
+### Stop Release Flow
+
+```
+1. Safety triggers (EMC, Bumper, etc.) → OnStop(state!=None) → Pause + EnterStop
+2. Safety clears → OnStop(None) → _stopCleared = true (wait for Start button)
+3. Operator presses Start → OnButtonPressed(Start) checks:
+   - IsInState(Stop) && _stopCleared
+   - Double-checks all PLC safety properties are false
+   → Fire(ReleaseStop) → System/Standby (Deep History)
+4. WatchThread detects Standby → SwichModeChanged(plcMode) → Auto (Deep History)
+   → Resumes order/navigation from where it was interrupted
+```
+
+### Mode Change Flow (with Order Preservation)
+
+```
+Auto/Executing/Moving → PLC switch to MANUAL
+    → SwichModeChanged(MANUAL):
+      1. IsInState(Auto) → Pause() → NavigationManager.Pause()
+      2. Unsubscribe order events
+      3. Fire(EnterManual) → exits Auto (Auto remembers Deep History: Executing/Moving)
+      → State: Manual
+
+PLC switch back to AUTOMATIC
+    → SwichModeChanged(AUTOMATIC):
+      1. Fire(EnterAuto) → Auto (Deep History: Executing/Moving restored)
+      2. Subscribe order events (prevent duplicates: unsub then sub)
+      3. Resume() → NavigationManager.Resume()
+      → State: Auto/Executing/Moving (resumed)
+```
+
+---
+
+## 12. Known Issues and TODOs
+
+1. ~~**Pause/Resume not implemented**~~: **FIXED** - `Pause()` calls `OrderManager.PauseOrder()` + `ActionManager.PauseActions()`, `Resume()` calls `OrderManager.ResumeOrder()` + `ActionManager.ResumeActions()`. Used for Stop, mode changes, and fleet Pause/Resume via `START_PAUSE`/`STOP_PAUSE` actions.
+
+2. ~~**HandleOrderStop fires EnterAuto**~~: **FIXED** - Now fires `CompleteExecution` for proper `Executing → Idle` transition.
+
+3. **Many ACT sub-state events never triggered**: `StartDocking`, `CompleteDocking`, `StartCharging`, etc. are defined in the state machine but no code fires them. Actions are still placeholder implementations.
+
+4. ~~**ReleaseStop not triggered**~~: **FIXED** - `OnButtonPressed(Start)` fires `ReleaseStop` when safety cleared + Start pressed. `ExitFault` is not yet triggered (manual intervention path TBD).
+
+5. **Many actions are placeholders**: `DOCK_TO`, `START_CHARGING`, `STOP_CHARGING`, `SCRIPT`, `MOVE_STRAIGHT_TO_COOR`, `LIFT_ROTATE` either finish immediately or have empty implementations.
+
+6. **RobotScriptAction has a bug**: In `Initialize()`, line 43: `if(!string.IsNullOrEmpty(para.Value))` should be `if(string.IsNullOrEmpty(para.Value))` - the logic is inverted.
+
+7. **StopRobot vs EmergencyStop**: Two different stop methods:
+   - `StopRobot()`: Sends zero velocity via `IInverseKinematics.SetVelocity(zeroTwist)` - used in Paused, Canceling, Manual, Service, Remote_Override, ACT, ExitMoving
+   - `EmergencyStop()`: Sends zero velocity + calls `IInverseKinematics.Disable()` - used only in Stop and Fault states
+   - Note: `ExitStop()` does not re-enable IK. This may need to be added for proper Stop release.
+
+8. **Async blocking pattern**: Many async operations use `.GetAwaiter().GetResult()` which blocks threads. This is a known trade-off for state machine entry actions that must be synchronous.
+
+9. **Paused state reserved for future use**: The `Paused` state (sub-state of Auto) with `PauseExecution`/`ResumeExecution` events exists in the state machine but is intentionally not used yet. Current pause/resume is done at order level (NavigationManager.Pause/Resume) without changing the state machine state.
+
+10. ~~**WatchThread overrides RF Handle's Service state**~~: **FIXED** - Added `_rfHandleHasPriority` flag. WatchThread mode mismatch check is skipped when RF Handle has priority. Backup stop detection always runs.
+
+11. ~~**PLC OnPeripheralModeChanged overrides RF Handle**~~: **FIXED** - PLC mode changes go through `OnPlcModeChanged()` wrapper which checks `_rfHandleHasPriority` before delegating to `SwichModeChanged()`.
+
+12. ~~**RF Handle EStop doesn't sync StateMachine**~~: **FIXED** - `DetermineStateFromRfHandle()` no longer clears `_externallySetState` on EStop. ManualControlService stays in SafeStop but remembers Maintenance/Override state for recovery. RF Handle disconnect fires `OnRfModeChanged(None)` to release priority.
+
+13. ~~**Race conditions between multiple threads**~~: **FIXED** - All state transition methods in RobotController use `lock(_stateTransitionLock)`: `OnPlcModeChanged`, `OnRfModeChanged`, `OnStop`, `OnButtonPressed`, `OnNewFatalError`, `WatchThreadCallback`.
+
+---
+
+## 12. Complete Flow Example: Order A→B(PICK)→C(DROP)
+
+```
+1. Fleet Manager sends OrderMsg [A→B→C] via MQTT
+2. IRobotEventBus.PublishOrderMessageReceived()
+3. RobotController.NewOrderUpdated()
+   - Checks StateManager.IsInState(Auto) → true
+   - Calls RobotOrderController.UpdateOrder(order)
+4. HandleNewOrder():
+   - ValidateNodes: A (no action), B (+PICK), C (+DROP)
+   - ValidateEdges: A→B, B→C
+   - AddAction(PICK, nodeB), AddAction(DROP, nodeC)
+   - ActionManager.AddOrderActions([PICK, DROP])
+5. OrderHandler() cycle:
+   - HasNewOrder=true, Nodes[0] (A) has no actions
+   - NavigationManager.Move(Nodes, Edges)
+   - Fire(StartExecution) → State becomes Executing/Moving
+   - Subscribe OnNavigationFinished, OnSafetySpeedChanged
+6. Robot navigates A→B...
+7. GetCurrentNode() detects robot at B:
+   - LastNode = B, ClearLastNode()
+   - B has PICK (HARD) → NavigationManager.Pause(), IsWaitingPaused=true
+   - Enqueue PICK action
+8. Navigation paused confirmed:
+   - ActionManager.StartOrderAction("PICK")
+   - ActionHard = PICK
+9. PICK runs (200ms timer):
+   - StartAction(): count=0
+   - ExecuteAction() x10 cycles (~2s): count > 10 → LoadManager.ClearLoad() → FINISHED
+10. PICK done, ActionHard = null
+    - ActionWaitingRunning empty, IsWaitingPaused → NavigationManager.Resume()
+11. Robot navigates B→C...
+12. Same flow for DROP at C
+13. NavigationFinished(Completed):
+    - Last node C, no more actions
+    - HandleOrderStop() → Dispose timer, Fire(CompleteExecution) → State = Auto/Idle
+```

+    style Business fill:#fff0e6
+    style State fill:#e6ffe6
+    style Process fill:#e6ffe6
+    style Error fill:#ffe6e6
+```
+
+**Validation Checks**:
+
+1. **JSON Schema Validation**:
+   - Use official VDA 5050 JSON schemas
+   - Validate structure and data types
+   - Check required fields
+
+2. **Business Logic Validation**:
+   - Sequence IDs: Nodes (even), Edges (odd), sequential
+   - Node/Edge relationships: Edges connect nodes properly
+   - Released flags: Valid release sequence
+   - Order updates: orderUpdateId increments correctly
+
+3. **State Consistency Validation**:
+   - Order progress matches current order
+   - Position matches mapId
+   - Action states match order actions
+
+### Testing Strategy
+
+**Testing Approach**:
+
+```mermaid
+graph TB
+    subgraph "Test Levels"
+        Unit[Unit Tests<br/>Message Parsing<br/>Validation Logic]
+        Integration[Integration Tests<br/>MQTT Communication<br/>End-to-end Flow]

+    Interop --> Valid
+    
+    style Unit fill:#e6f3ff
+    style Integration fill:#fff0e6
+    style Interop fill:#e6ffe6
+```
+
+**Key Test Scenarios**:
+
+1. **Order Handling**:
+   - Valid order acceptance
+   - Invalid order rejection
+   - Order update handling (same orderId, higher orderUpdateId)
+   - Order replacement (new orderId)
+   - Sequence ID ordering
+   - Released vs unreleased nodes/edges
+
+2. **State Reporting**:
+   - Publishing frequency (1-10 Hz)
+   - Required fields present
+   - Position accuracy
+   - Battery state correctness
+   - Action state updates
+   - Error reporting
+
+3. **Instant Actions**:
+   - stopPause immediate response (< 50ms)
+   - cancelOrder order cancellation
+   - Resume after pause
+
+4. **Connection Management**:
+   - MQTT disconnection handling
+   - Auto-reconnection
+   - Missed message handling
+   - Connection state reporting
+
+5. **Interoperability**:
+   - Third-party Fleet Manager compatibility
+   - Third-party robot compatibility
+   - VDA 5050 conformance validation

+
+**Key Metrics**:
+- Message processing time
+- State update frequency
+- Error rates
+- Connection stability
+
+## 🔄 Common Scenarios / Các Tình huống Thường gặp
+
+### Scenario 1: Simple Transport Mission
+
+**FleetManager sends**:
+```json
+{
+  "orderId": "TRANSPORT-001",
+  "orderUpdateId": 0,
+  "nodes": [
+    {"nodeId": "A", "sequenceId": 0, "released": true, "nodePosition": {...}},
+    {"nodeId": "B", "sequenceId": 2, "released": true, "nodePosition": {...}}
+  ],
+  "edges": [
+    {"edgeId": "A-B", "sequenceId": 1, "released": true,
+     "startNodeId": "A", "endNodeId": "B"}
+  ]
+}
+```
+
+**RobotApp executes**:
+1. Receives order
+2. Moves to node A (sequenceId 0)
+3. Reaches node A, updates state (lastNodeId = "A", lastNodeSequenceId = 0)
+4. Follows edge A-B (sequenceId 1)
+5. Reaches node B (sequenceId 2)
+6. Updates state (lastNodeId = "B", lastNodeSequenceId = 2, driving = false)
+
+### Scenario 2: Pick and Place with Actions
+
+**FleetManager sends**:
+```json
+{
+  "orderId": "PICK-PLACE-001",
+  "orderUpdateId": 0,
+  "nodes": [
+    {
+      "nodeId": "PICK",
+      "sequenceId": 0,
+      "released": true,
+      "actions": [
+        {"actionId": "pick1", "actionType": "pick", "blockingType": "HARD"}
+      ]
+    },
+    {
+      "nodeId": "DROP",
+      "sequenceId": 2,
+      "released": true,
+      "actions": [
+        {"actionId": "drop1", "actionType": "drop", "blockingType": "HARD"}
+      ]
+    }
+  ],
+  "edges": [...]
+}
+```
+
+**RobotApp executes**:
+1. Moves to PICK node
+2. Executes pick action (actionStates: RUNNING → FINISHED)
+3. Moves to DROP node
+4. Executes drop action
+5. Reports completion
+
+### Scenario 3: Order Update (Add Waypoint)
+
+**Initial order**:
+```json
+{"orderId": "ORD-001", "orderUpdateId": 0, "nodes": ["A", "B"]}
+```
+
+**Updated order** (add node C):
+```json
+{"orderId": "ORD-001", "orderUpdateId": 1, "nodes": ["A", "B", "C"]}
+```
+
+**RobotApp behavior**:
+- Recognize same orderId with higher orderUpdateId
+- Continue current node/edge
+- Append new nodes to plan
+- Update state with new orderUpdateId
+
+### Scenario 4: Emergency Stop
+
+**FleetManager sends InstantAction**:
+```json
+{
+  "instantActions": [
+    {"actionId": "stop1", "actionType": "stopPause", "blockingType": "HARD"}
+  ]
+}
+```
+
+**RobotApp behavior**:
+1. Immediately stop motion
+2. Set `paused = true` in state
+3. Continue publishing state
+4. Wait for resume command

+
+**✅ Acceptable (không cần thiết):**
+- Getters, setters đơn giản return `void` (standard C pattern, acceptable)
+- Free functions return `void` (standard C pattern, acceptable)
+
+### 1.2. Functions Cần Cải Thiện
+
+#### Functions trả về `void` (không có error handling) - **NON-CRITICAL**:
+- ✅ `ceres_wrapper_problem_set_parameter_block_constant()` - Simple setter, có thể chấp nhận
+- ✅ `ceres_wrapper_problem_set_parameter_block_variable()` - Simple setter, có thể chấp nhận
+- ✅ `ceres_wrapper_problem_set_manifold()` - Simple setter, có thể chấp nhận
+- ✅ `ceres_wrapper_free_*()` functions - Free functions, có thể chấp nhận
+- ✅ Tất cả các `set_*` functions trong SolverOptions, ProblemOptions, etc. - Simple setters
+
+#### Functions trả về `int` (0/1) - **OPTIONAL ENHANCEMENT**:
+- ⚠️ `ceres_wrapper_covariance_compute()` - Returns 1/0 (optional - có thể enhance)
+- ⚠️ `ceres_wrapper_covariance_get_covariance_block()` - Returns 1/0 (optional)
+- ⚠️ `ceres_wrapper_covariance_get_covariance_matrix()` - Returns 1/0 (optional)

+
+#### Functions trả về pointer (NULL = error) - **ACCEPTABLE**:
+- ✅ `ceres_wrapper_create_*()` functions - Return NULL on error (standard C pattern, acceptable)
+
+### 1.3. Status
+
+**✅ Đã hoàn thành 100%:**
+1. ✅ Tất cả critical functions đã có error handling

+   - Free functions - Giữ nguyên `void` return (standard pattern)
+   - Create functions - Giữ nguyên NULL return (standard C pattern)
+   - `ceres_wrapper_solver_options_is_valid()` - Giữ nguyên `int` return (validation function)
+
+**Status: ✅ COMPLETE (100%)** - Tất cả functions cần error handling đã có đầy đủ
+
+---
+
+## 2. Optional Loss Functions - ✅ **COMPLETE** ⬆️
+
+### 2.1. Tình Trạng Hiện Tại
+
+**✅ Đã có (100%):**
+- `ceres_wrapper_create_huber_loss()` - ⭐ **CRITICAL cho Cartographer**
+- `ceres_wrapper_create_trivial_loss()`
+- `ceres_wrapper_create_cauchy_loss()`
+- `ceres_wrapper_create_softl1_loss()`
+- `ceres_wrapper_create_arctan_loss()`
+- `ceres_wrapper_create_tolerant_loss()`
+- ✅ `ceres_wrapper_create_composed_loss()` - ⭐ **NEW** - Compose two loss functions
+- ✅ `ceres_wrapper_create_scaled_loss()` - ⭐ **NEW** - Scale a loss function
+
+**Status:** ✅ **COMPLETE** - Tất cả loss functions bao gồm optional ones đã có đầy đủ
+
+### 2.2. Chi Tiết
+
+**ComposedLoss:**
+- Trong Ceres: `ceres::ComposedLoss(const LossFunction* f, Ownership ownership_f, const LossFunction* g, Ownership ownership_g)`
+- Use case: Compose two loss functions: `ComposedLoss(f, g)` evaluates `f(g(s))`
+- Impact: **LOW** - Ít khi cần thiết
+
+**ScaledLoss:**
+- Trong Ceres: `ceres::ScaledLoss(const LossFunction* rho, double a, Ownership ownership)`
+- Use case: Scale a loss function by a scalar: `ScaledLoss(rho, a)` evaluates `a * rho(s)`
+- Impact: **LOW** - Có thể workaround bằng cách scale residuals trước
+
+### 2.3. Status
+
+**✅ Đã hoàn thành:**
+- ComposedLoss và ScaledLoss đã được implement
+- Full integration với Problem API
+- Test cases đã được thêm
+
+**Implementation:**
+```c
+CERES_WRAPPER_EXPORT ceres_wrapper_loss_function_t* 
+ceres_wrapper_create_composed_loss(
+    ceres_wrapper_loss_function_t* f,
+    int ownership_f,
+    ceres_wrapper_loss_function_t* g,
+    int ownership_g);
+
+CERES_WRAPPER_EXPORT ceres_wrapper_loss_function_t* 
+ceres_wrapper_create_scaled_loss(
+    ceres_wrapper_loss_function_t* rho,
+    double a,
+    int ownership);
+```
+
+**Impact:** LOW - Optional nhưng đã có đầy đủ cho advanced use cases
+
+---
+
+## 3. Official C API Integration - ✅ **GOOD**
+
+### 3.1. Tình Trạng Hiện Tại
+
+**✅ Đã tích hợp:**
+- Test file sử dụng `ceres_create_problem()` và `ceres_free_problem()` từ official C API
+- Wrapper không conflict với official C API naming
+- Wrapper bổ sung các APIs mà official C API thiếu
+
+**⚠️ Có thể cải thiện:**
+- Wrapper không include `c_api.h` trực tiếp trong implementation
+- Có thể document rõ hơn về việc sử dụng official C API
+
+### 3.2. Official C API Functions Được Sử Dụng
+
+Từ `refs/ceres-solver/include/ceres/c_api.h`:
+- ✅ `ceres_init()` - Initialization (used in test)
+- ✅ `ceres_create_problem()` - Create problem (used in test)
+- ✅ `ceres_free_problem()` - Free problem (used in test)
+- ✅ `ceres_problem_add_residual_block()` - For callback-based cost functions (mentioned in doc)
+
+### 3.3. Đề Xuất
+
+**Priority: LOW** (không phải vấn đề)
+
+- Có thể thêm comment trong code về việc sử dụng official C API
+- Có thể thêm include guard để tránh conflict
+
+**Impact:** LOW - Không ảnh hưởng đến functionality

+- Migration guide từ C++ API sang C API
+- Performance notes
+
+### 4.2. Đề Xuất
+
+**Priority: LOW** (có thể làm sau khi C# wrapper hoàn thành)
+
+**Impact:** LOW - Documentation hiện tại đủ cho development
+
+---
+
+## 5. Testing Coverage - ✅ **GOOD**
+
+### 5.1. Tình Trạng Hiện Tại
+
+**✅ Đã có:**
+- Test file (`ceres_wrapper_test.c`) với nhiều test cases
+- Tests cho các critical features:
+  - Problem operations
+  - Cost functions
+  - Loss functions
+  - Manifolds
+  - Interpolators
+  - Solver options
+
+**⚠️ Có thể cải thiện:**
+- Unit tests cho error handling

+- Performance benchmarks
+
+### 5.2. Đề Xuất
+
+**Priority: LOW** (có thể làm trong quá trình C# development)
+
+**Impact:** LOW - Test coverage hiện tại đủ
+
+---
+

+# Hướng dẫn Build Linux Kernel Realtime
+
+Hướng dẫn này mô tả cách build Linux kernel với patch realtime (RT) để có độ trễ thấp cho các ứng dụng thời gian thực.
+
+## Phiên bản sử dụng
+
+- **Kernel**: Linux 6.6.116
+- **RT Patch**: patch-6.6.116-rt66
+
+## Yêu cầu hệ thống
+
+### Phần cứng tối thiểu
+- RAM: ít nhất 4GB (khuyến nghị 8GB+)
+- Ổ cứng: ít nhất 20GB dung lượng trống
+- CPU: hỗ trợ đa nhân để tăng tốc quá trình build
+
+### Phần mềm cần thiết (Ubuntu/Debian)
+```bash
+sudo apt update
+sudo apt install -y build-essential libncurses-dev bison flex libssl-dev libelf-dev \
+    fakeroot dwarves zstd liblz4-tool bc kmod cpio initramfs-tools \
+    git wget curl xz-utils debhelper
+```
+
+## Bước 1: Tải xuống Kernel và RT Patch
+
+### Tạo thư mục làm việc
+```bash
+mkdir -p ~/kernel-build
+cd ~/kernel-build
+```
+
+### Tải kernel source
+```bash
+wget https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/linux-6.6.116.tar.xz
+```
+
+### Tải RT patch
+```bash
+wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/6.6/patch-6.6.116-rt66.patch.xz
+```
+
+### Kiểm tra tính toàn vẹn (tùy chọn)
+```bash
+# Tải signature files để verify (nếu có)
+wget https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/linux-6.6.116.tar.sign
+wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/6.12/patch-6.6.116-rt66.patch.sign
+```
+
+## Bước 2: Giải nén và áp dụng RT Patch
+
+### Giải nén kernel
+```bash
+tar -xf linux-6.6.116.tar.xz
+cd linux-6.6.116
+```
+
+### Giải nén và áp dụng RT patch
+```bash
+xzcat ../patch-6.6.116-rt66.patch.xz | patch -p1
+```
+
+**Lưu ý**: Nếu có lỗi khi patch, kiểm tra:
+- Đảm bảo đang ở trong thư mục kernel source
+- Kiểm tra phiên bản patch có khớp với kernel không
+- Có thể cần `--dry-run` để test trước: `patch -p1 --dry-run < ../patch-6.6.116-rt66.patch`
+
+## Bước 3: Cấu hình Kernel
+
+### Sao chép cấu hình hiện tại (khuyến nghị)
+```bash
+cp /boot/config-$(uname -r) .config
+```
+
+### Hoặc tạo cấu hình mặc định
+```bash
+make defconfig
+```
+
+### Cấu hình RT-specific options
+```bash
+make menuconfig
+```
+
+**Đường dẫn cụ thể trong menuconfig để cấu hình RT (Kernel 6.6.116-rt66):**
+
+#### 1. High Resolution Timers và Tick Handling
+```
+General setup --->
+  Timers subsystem --->
+    [*] High Resolution Timer Support (CONFIG_HIGH_RES_TIMERS)
+    Timer tick handling (Full dynticks system (tickless)) --->
+      (X) Full dynticks system (tickless) (CONFIG_NO_HZ_FULL)
+```
+
+#### 2. RT Preemption Model (QUAN TRỌNG NHẤT)
+```
+General setup --->
+  [*] Expert users only (CONFIG_EXPERT) - PHẢI BẬT TRƯỚC
+  Preemption Model (Fully Preemptible Kernel (Real-Time)) --->  
+    (X) Fully Preemptible Kernel (Real-Time) (CONFIG_PREEMPT_RT)
+```
+
+**Lưu ý quan trọng**: 
+- PHẢI bật `CONFIG_EXPERT=y` trước khi có thể thấy option `PREEMPT_RT`
+- Option này nằm trong `General setup`, KHÔNG phải `Processor type and features`
+
+#### 3. Kernel Tracing (để debug RT latency)
+```
+Kernel hacking --->
+  Tracers --->
+    [*] Kernel Function Tracer (CONFIG_FUNCTION_TRACER)
+    [*] Preemption-off Latency Tracer (CONFIG_PREEMPT_TRACER)
+    [*] Interrupts-off Latency Tracer (CONFIG_IRQSOFF_TRACER)  
+    [*] Scheduling Latency Tracer (CONFIG_SCHED_TRACER)
+    [*] Trace max stack (CONFIG_STACK_TRACER)
+```
+
+#### 4. Tắt Debug Info (giảm kích thước package)
+```
+Kernel hacking --->
+  Compile-time checks and compiler options --->
+    [ ] Compile the kernel with debug info (CONFIG_DEBUG_INFO) - TẮT
+    [ ] Generate BTF typeinfo (CONFIG_DEBUG_INFO_BTF) - TẮT
+```
+
+#### 5. Processor Features (Tùy chọn thêm)
+```
+Processor type and features --->
+  Timer frequency (1000 HZ) --->
+    (X) 1000 HZ (CONFIG_HZ_1000) - Khuyến nghị cho RT
+  [*] Symmetric multi-processing support (CONFIG_SMP)
+```
+
+### Kiểm tra và xóa TRUSTED_KEYS/REVOCATION_KEYS
+Khi copy config từ máy khác, cần kiểm tra và xóa các key không tồn tại:
+
+```bash
+# Kiểm tra các key files
+grep -E "CONFIG_SYSTEM_TRUSTED_KEYS|CONFIG_SYSTEM_REVOCATION_KEYS" .config
+
+# Xóa các key files không tồn tại
+scripts/config --set-str CONFIG_SYSTEM_TRUSTED_KEYS ""
+scripts/config --set-str CONFIG_SYSTEM_REVOCATION_KEYS ""
+```
+
+### Cấu hình nhanh bằng scripts (thay vì menuconfig)
+Nếu không muốn dùng menuconfig, có thể cấu hình nhanh bằng lệnh:
+
+```bash
+# QUAN TRỌNG: Phải enable EXPERT trước
+scripts/config --enable CONFIG_EXPERT
+
+# Enable RT preemption và các tùy chọn cần thiết  
+scripts/config --enable CONFIG_PREEMPT_RT
+scripts/config --enable CONFIG_HIGH_RES_TIMERS
+scripts/config --enable CONFIG_NO_HZ_FULL
+scripts/config --set-val CONFIG_HZ_1000 y
+scripts/config --set-val CONFIG_HZ 1000
+
+# Enable tracing cho debug RT latency
+scripts/config --enable CONFIG_PREEMPT_TRACER
+scripts/config --enable CONFIG_IRQSOFF_TRACER  
+scripts/config --enable CONFIG_SCHED_TRACER
+scripts/config --enable CONFIG_FUNCTION_TRACER
+scripts/config --enable CONFIG_STACK_TRACER
+
+# Tắt debug symbols để giảm kích thước package

+
+## Bước 4: Build Kernel
+
+### Kiểm tra số CPU cores
+```bash
+nproc
+```
+
+### Build kernel packages (không tạo debug packages)
+```bash
+make -j$(nproc) bindeb-pkg
+```
+
+**Lưu ý về bindeb-pkg:**
+- `bindeb-pkg`: Tạo binary packages (.deb) không có debug symbols
+- Nhanh hơn và tạo ra file nhỏ hơn so với `deb-pkg`
+- Không tạo ra `linux-image-*-dbg.deb` (debug package)
+
+**Các tùy chọn build khác (nếu cần):**
+```bash
+# Build kernel image only
+make -j$(nproc)
+
+# Build modules only
+make -j$(nproc) modules
+
+# Build với debug (không khuyến nghị - tạo file lớn)
+make -j$(nproc) deb-pkg
+```
+
+### Kiểm tra cấu hình trước khi build
+```bash
+# Kiểm tra các config quan trọng
+grep -E "CONFIG_PREEMPT_RT|CONFIG_HIGH_RES_TIMERS|CONFIG_NO_HZ_FULL" .config
+grep -E "CONFIG_CPU_FREQ|CONFIG_CPU_IDLE" .config
+grep -E "CONFIG_DEBUG_INFO" .config
+
+# Kết quả mong muốn:
+# CONFIG_PREEMPT_RT=y
+# CONFIG_HIGH_RES_TIMERS=y  
+# CONFIG_NO_HZ_FULL=y
+# # CONFIG_CPU_FREQ is not set
+# # CONFIG_CPU_IDLE is not set
+# # CONFIG_DEBUG_INFO is not set
+```
+
+**Thời gian build**: Khoảng 30 phút - 2 giờ tùy theo cấu hình máy.
+
+## Bước 5: Cài đặt Kernel
+
+### Cài đặt từ Debian packages
+
+#### Cách 1: Cài đặt trực tiếp vào hệ thống
+```bash
+cd ..
+# List các file .deb được tạo
+ls -la linux-*.deb
+
+# Cài đặt kernel packages (không có debug package)
+sudo dpkg -i linux-image-*.deb linux-headers-*.deb
+```
+
+#### Cách 2: Cài đặt vào folder đặc biệt (khuyến nghị để test)
+```bash
+cd ..
+# Tạo folder để cài kernel tạm thời
+sudo mkdir -p /opt/rt-kernel
+export KERNEL_INSTALL_DIR="/opt/rt-kernel"
+
+# Giải nén package để kiểm tra nội dung trước
+dpkg-deb --extract linux-image-*.deb $KERNEL_INSTALL_DIR/
+dpkg-deb --extract linux-headers-*.deb $KERNEL_INSTALL_DIR/
+
+# Xem cấu trúc files được cài
+ls -la $KERNEL_INSTALL_DIR/
+tree $KERNEL_INSTALL_DIR/ || find $KERNEL_INSTALL_DIR/ -type f | head -20
+
+# Copy kernel files vào /boot từ folder tạm
+sudo cp $KERNEL_INSTALL_DIR/boot/vmlinuz-* /boot/
+sudo cp $KERNEL_INSTALL_DIR/boot/initrd.img-* /boot/ 
+sudo cp $KERNEL_INSTALL_DIR/boot/System.map-* /boot/
+sudo cp $KERNEL_INSTALL_DIR/boot/config-* /boot/
+
+# Copy modules vào /lib/modules
+sudo cp -r $KERNEL_INSTALL_DIR/lib/modules/* /lib/modules/
+
+# Tạo symbolic links (nếu cần)
+sudo ln -sf /boot/vmlinuz-6.6.116-rt66 /boot/vmlinuz-rt
+sudo ln -sf /boot/initrd.img-6.6.116-rt66 /boot/initrd.img-rt
+```
+
+#### Cách 3: Sử dụng dpkg với --root option
+```bash
+cd ..
+# Cài vào thư mục riêng để kiểm tra
+sudo mkdir -p /tmp/kernel-staging
+sudo dpkg --root=/tmp/kernel-staging -i linux-image-*.deb
+
+# Xem files sẽ được cài
+find /tmp/kernel-staging -name "vmlinuz*" -o -name "initrd*"
+
+# Copy thủ công vào hệ thống sau khi kiểm tra
+sudo cp /tmp/kernel-staging/boot/* /boot/
+sudo cp -r /tmp/kernel-staging/lib/modules/* /lib/modules/
+```
+
+**Files được tạo bởi bindeb-pkg:**
+- `linux-image-*-rt*.deb` - Kernel image và modules
+- `linux-headers-*-rt*.deb` - Headers cho development
+- `linux-libc-dev_*.deb` - Libc development files
+
+### Cập nhật bootloader
+```bash
+sudo update-grub
+```
+
+### Đặt RT kernel làm mặc định
+Sau khi cài đặt và update-grub, cần đặt RT kernel làm boot option mặc định:
+
+#### Cách 1: Sử dụng grub-set-default
+```bash
+# Liệt kê các kernel entries trong GRUB
+grep "menuentry\|submenu" /boot/grub/grub.cfg | grep -E "(rt|6\.6\.116)"
+
+# Đặt kernel RT làm mặc định (thay số 0 bằng index thực tế)
+sudo grub-set-default "1>2"  # Ví dụ: submenu 1, entry 2
+
+# Hoặc sử dụng tên đầy đủ
+sudo grub-set-default "Advanced options for Ubuntu>Ubuntu, with Linux 6.6.116-rt66"
+```
+
+#### Cách 2: Chỉnh sửa /etc/default/grub
+```bash
+# Backup file gốc
+sudo cp /etc/default/grub /etc/default/grub.backup
+
+# Chỉnh sửa GRUB_DEFAULT
+sudo nano /etc/default/grub
+```
+
+Thay đổi dòng:
+```bash
+# Từ:
+GRUB_DEFAULT=0
+
+# Thành (với saved):
+GRUB_DEFAULT=saved
+GRUB_SAVEDEFAULT=true
+
+# Hoặc chỉ định trực tiếp:
+GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 6.6.116-rt66"
+```
+
+#### Cách 3: Sử dụng grub-reboot (tạm thời)
+```bash
+# Boot vào RT kernel chỉ cho lần khởi động tiếp theo
+sudo grub-reboot "Advanced options for Ubuntu>Ubuntu, with Linux 6.6.116-rt66"
+```
+
+### Cập nhật GRUB sau khi thay đổi
+```bash
+sudo update-grub
+```
+
+## Bước 6: Khởi động với RT Kernel
+
+### Reboot và chọn kernel
+```bash
+sudo reboot
+```
+
+Trong GRUB menu, chọn kernel mới với tên có chứa "rt" hoặc version 6.6.116.
+
+### Kiểm tra RT kernel đã load
+```bash
+uname -a
+# Nên thấy output có chứa "rt12" và "PREEMPT_RT"
+
+cat /sys/kernel/realtime
+# Nên output "1" nếu RT enabled
+```
+
+### Kiểm tra kernel mặc định hiện tại
+```bash
+# Xem kernel nào sẽ boot mặc định
+sudo grub-editenv list
+
+# Xem tất cả kernel entries có sẵn
+awk -F\' '/menuentry |submenu / {print $1 $2}' /boot/grub/grub.cfg
+
+# Kiểm tra GRUB_DEFAULT hiện tại
+grep "GRUB_DEFAULT" /etc/default/grub
+```
+
+### Xóa kernel cũ (tùy chọn)
+Sau khi đã chắc chắn RT kernel hoạt động tốt:
+
+#### Nếu cài bằng dpkg trực tiếp:
+```bash
+# Liệt kê các kernel packages đã cài
+dpkg --list | grep linux-image
+
+# Xóa kernel cũ (cẩn thận!)
+sudo apt remove linux-image-<version-cũ>
+sudo apt autoremove
+
+# Cập nhật GRUB sau khi xóa
+sudo update-grub
+```
+
+#### Nếu cài từ folder đặc biệt:
+```bash
+# Xóa files kernel cũ từ /boot
+sudo rm /boot/vmlinuz-<version-cũ>
+sudo rm /boot/initrd.img-<version-cũ>
+sudo rm /boot/System.map-<version-cũ>
+sudo rm /boot/config-<version-cũ>
+
+# Xóa modules cũ
+sudo rm -rf /lib/modules/<version-cũ>
+
+# Cleanup staging folder
+sudo rm -rf /opt/rt-kernel
+sudo rm -rf /tmp/kernel-staging
+
+# Cập nhật GRUB
+sudo update-grub
+```
+
+## Bước 7: Tối ưu hóa hệ thống cho RT
+
+### Kernel parameters
+Thêm vào `/etc/default/grub`:
+```bash
+GRUB_CMDLINE_LINUX_DEFAULT="quiet splash isolcpus=1-3 nohz_full=1-3 rcu_nocbs=1-3"
+```
+
+Trong đó:
+- `isolcpus=1-3`: Cô lập CPU cores 1-3 cho RT tasks
+- `nohz_full=1-3`: Tắt timer interrupts trên cores này
+- `rcu_nocbs=1-3`: RCU callbacks không chạy trên cores này
+
+### RT scheduling policy
+```bash
+# Set RT priority cho process
+sudo chrt -f 99 your_rt_application
+
+# Check RT processes
+ps -eo pid,cls,rtprio,ni,comm | grep -E "(FF|RR)"
+```
+
+### Memory locking
+```bash
+# Lock memory để tránh page faults
+ulimit -l unlimited
+```
+
+## Kiểm tra hiệu năng RT
+
+### Test latency với cyclictest
+```bash
+# Cài đặt rt-tests
+sudo apt install rt-tests
+
+# Test latency cơ bản
+cyclictest -t1 -p99 -n -i200 -l1000
+
+# Test stress với load
+cyclictest -t4 -p99 -n -i200 -l10000 -q
+```
+
+### Test với hackbench
+```bash
+hackbench -l 10000
+```
+
+## Xử lý sự cố
+
+### Lỗi build do TRUSTED_KEYS
+```bash
+# Nếu gặp lỗi về certificate/key files
+make[4]: *** No rule to make target 'debian/canonical-certs.pem'
+
+# Giải pháp: Xóa các key files
+scripts/config --set-str CONFIG_SYSTEM_TRUSTED_KEYS ""
+scripts/config --set-str CONFIG_SYSTEM_REVOCATION_KEYS ""
+make clean && make -j$(nproc) bindeb-pkg
+```
+
+### GRUB không hiện RT kernel
+```bash
+# Nếu không thấy RT kernel trong GRUB menu
+sudo update-grub
+sudo grub-install /dev/sda  # thay sda bằng disk thực tế
+
+# Kiểm tra kernel files có tồn tại không
+ls -la /boot/vmlinuz-*rt*
+ls -la /boot/initrd.img-*rt*
+
+# Nếu cài từ folder đặc biệt, kiểm tra permissions
+sudo chmod 644 /boot/vmlinuz-*rt*
+sudo chmod 644 /boot/initrd.img-*rt*
+sudo chown root:root /boot/vmlinuz-*rt* /boot/initrd.img-*rt*
+
+# Rebuild initramfs nếu cần
+sudo update-initramfs -u -k 6.6.116-rt66
+```
+
+### Kernel files không đúng vị trí (khi cài từ folder đặc biệt)
+```bash
+# Kiểm tra kernel modules đã được copy chưa
+ls -la /lib/modules/ | grep rt
+
+# Nếu thiếu modules, copy lại từ staging folder
+sudo cp -r /opt/rt-kernel/lib/modules/6.6.116-rt66 /lib/modules/
+
+# Update module dependencies
+sudo depmod -a 6.6.116-rt66
+
+# Kiểm tra symbolic links
+ls -la /boot/ | grep -E "vmlinuz$|initrd.img$"
+```
+
+### Không boot được vào RT kernel
+```bash
+# Boot vào kernel cũ và kiểm tra
+journalctl -b -1 | grep -i error
+
+# Kiểm tra kernel modules
+sudo depmod -a 6.6.116-rt66
+sudo update-initramfs -u -k 6.6.116-rt66
+
+# Reset GRUB default về kernel cũ
+sudo grub-set-default 0
+sudo update-grub
+```
+
+### Kernel panic khi boot
+- Boot với kernel cũ từ GRUB
+- Kiểm tra logs: `dmesg` hoặc `/var/log/kern.log`
+- Có thể cần disable một số drivers/modules
+
+### Hiệu năng kém
+- Kiểm tra `CONFIG_PREEMPT_RT=y` trong `/boot/config-*`
+- Verify kernel parameters với `cat /proc/cmdline`
+- Check IRQ affinity: `cat /proc/interrupts`
+
+### Module driver không tương thích
+```bash
+# List missing modules
+dmesg | grep -i "unknown symbol\|unresolved symbol"
+
+# Rebuild external modules
+sudo dkms autoinstall
+```
+
+### File .deb quá lớn
+Nếu vẫn tạo ra file quá lớn:
+```bash
+# Kiểm tra debug info đã tắt chưa
+grep DEBUG_INFO .config
+
+# Nên thấy:
+# CONFIG_DEBUG_INFO is not set
+# CONFIG_DEBUG_INFO_BTF is not set
+```
+
+## Tham khảo
+
+- [Linux RT Wiki](https://rt.wiki.kernel.org/)
+- [Real-Time Linux Kernel Documentation](https://www.kernel.org/doc/Documentation/admin-guide/real-time-kernel.txt)
+- [RT-Tests Suite](https://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git)
+
+## Ghi chú
+
+- **Backup**: Luôn backup kernel cũ trước khi cài RT kernel
+- **Testing**: Test kỹ trên môi trường dev trước khi deploy production
+- **Updates**: RT patches thường ra sau kernel chính vài tuần/tháng
+- **Hardware**: Một số hardware cần firmware/drivers đặc biệt cho RT

+Tôi đang phát triển ứng dụng RobotApp (/home/robotics/anhnv/RobotNet10/srcs/RobotNet10/RobotApp/RobotNet10.RobotApp) dành cho mobile robot với chức năng điều khiển di chuyển, định vị robot và quét bản đồ (SLAM). 
+Phần định vị và quét bản đồ sẽ sử dụng CartographerSharp.
+CartographerSharp là thư viện c# viết lại cartographer project của google.
+CartographerSharp sử dụng thư viện ceres 2.2.0 thông qua CeresWrapper(C API tại /home/robotics/anhnv/RobotNet10/ipc/CeresWrapper) và CeresSharp(C# API tại /home/robotics/anhnv/RobotNet10/ipc/CeresSharp).
+Các project gốc C/C++ là cartographer project có trong thư mục /home/robotics/anhnv/RobotNet10/refs/xloc_cpp-main/third_party/cartographer.
+Và ceres solver project của google có trong thư mục /home/robotics/anhnv/RobotNet10/refs/ceres-solver.
+Project tham khảo xử lý slam với cartographer là xloc tại thư mục /home/robotics/anhnv/RobotNet10/refs/xloc-cpp_main
+
+Hiện tại chức năng di chuyển băng RobotNet10.RobotApp.Motion.ManualControlService đã hoạt động bình thường nhưng khi gọi RobotNet10.RobotApp.Localization.ScanMappingService.StartMappingAsync thì bị lỗi như trong log srcs/RobotNet10/RobotApp/RobotNet10.RobotApp/logs/log.txt 
+Có vẻ phần điều khiển manual và servo đang dùng các hàm bất đồng bộ nên bị tạm dừng khi phần scan mapping được gọi.
+Code hiện tại đang chạy trên CPU 20 core và lúc đó tài nguyên sử dụng CPU cũng rất thấp.
+Bạn hãy điều tra nguyên nhân và cho tôi phương án xử lý để có thể điều khiển manual đồng thời với scan mapping.
