+# System Architecture
+
+## 1. Overview
+The suite consists of a C++ server library (`libmarte_dev.so`) that instrument MARTe2 applications at runtime, and a native Rust client for visualization.
+
+## 2. Core Mechanism: Registry Patching
+The "Zero-Code-Change" requirement is met by intercepting the MARTe2 `ClassRegistryDatabase`. When the `DebugService` initializes, it replaces the standard object builders for critical classes:
+
+1.  **Broker Injection:** Standard Brokers (e.g., `MemoryMapInputBroker`) are replaced with `DebugBrokerWrapper`. This captures data every time a GAM reads or writes a signal.
+2.  **Scheduler Injection:** The `FastScheduler` is replaced with `DebugFastScheduler`. This provides hooks at the start/end of each real-time cycle for execution control (pausing).
+
+## 3. Communication Layer
+The system uses three distinct channels:
+
+### 3.1 Command & Control (TCP Port 8080)
+- **Protocol:** Text-based over TCP.
+- **Role:** Object tree discovery (`TREE`), signal metadata (`DISCOVER`), and trace activation (`TRACE`).
+- **Response Format:** JSON for complex data, `OK/ERROR` for status.
+
+### 3.2 High-Speed Telemetry (UDP Port 8081)
+- **Protocol:** Binary over UDP.
+- **Format:** Packed C-structs.
+- **Header:** `[Magic:4][Seq:4][TS:8][Count:4]` (Packed, 20 bytes).
+- **Payload:** `[ID:4][Size:4][Data:N]` (Repeated for each traced signal).
+
+### 3.3 Log Streaming (TCP Port 8082)
+- **Protocol:** Real-time event streaming.
+- **Role:** Forwards global `REPORT_ERROR` calls from the framework to the GUI client.

+# Demo Walkthrough: High-Speed Tracing
+
+This demo demonstrates tracing a `Timer.Counter` signal at 100Hz and verifying its consistency.
+
+### 1. Launch the Test Environment
+Start the validation environment which simulates a real-time app:
+```bash
+./Build/Test/Integration/ValidationTest
+```
+*Note: The test will wait for a trace command before finishing.*
+
+### 2. Connect the GUI
+In another terminal:
+```bash
+cd Tools/gui_client
+cargo run --release
+```
+
+### 3. Explore the Tree
+1.  On the left panel (**Application Tree**), expand `Root.App.Data.Timer`.
+2.  Click the `ℹ Info` button on the `Timer` node to see its configuration (e.g., `SleepTime: 10000`).
+
+### 4. Activate Trace
+1.  Locate the `Counter` signal under the `Timer` node.
+2.  Click the **📈 Trace** button.
+3.  The **Oscilloscope** in the center will immediately begin plotting the incremental counter.
+4.  Verify the **UDP Packets** counter in the top bar is increasing rapidly.
+
+### 5. Test Execution Control
+1.  Click the **⏸ Pause** button in the top bar.
+2.  Observe that the plot stops updating and the counter value holds steady.
+3.  Click **▶ Resume** to continue execution.

-### Run
+## Features
-1. Start your MARTe2 application with the `DebugService` enabled.
+- **Live Tree:** Explore the MARTe2 object database in real-time.
-2. Launch the GUI:
+- **Oscilloscope:** Trace any signal at high frequency (100Hz+) with automatic scaling.
-   ```bash
+- **Signal Forcing:** Inject values directly into the real-time memory map.
-   ./Tools/gui_client/target/release/marte_debug_gui

+- **Execution Control:** Global pause/resume via scheduler-level hooks.
 
-## Communication Ports
+## Usage
-- **8080 (TCP)**: Commands (TREE, FORCE, TRACE, PAUSE).
+To enable debugging in your application, add the following to your `.cfg`:
-- **8082 (TCP)**: Real-time framework logs.
+```text
-- **8081 (UDP)**: Signal telemetry data.
++DebugService = {
+    Class = DebugService
+    ControlPort = 8080
+    UdpPort = 8081
+}
+```
+The suite automatically patches the registry to instrument your existing Brokers and Schedulers.

+# MARTe2 Debug Suite Specifications
+
+## 1. Goal
+Implement a "Zero-Code-Change" observability layer for the MARTe2 real-time framework, providing live telemetry, signal forcing, and execution control without modifying existing application source code.
+
+## 2. Requirements
+### 2.1 Functional Requirements (FR)
+- **FR-01 (Discovery):** Discover the full MARTe2 object hierarchy at runtime.
+- **FR-02 (Telemetry):** Stream high-frequency signal data (verified up to 100Hz) to a remote client.
+- **FR-03 (Forcing):** Allow manual override of signal values in memory during execution.
+- **FR-04 (Logs):** Stream global framework logs to a dedicated terminal.
+- **FR-05 (Execution Control):** Pause and resume the real-time execution threads via scheduler injection.
+- **FR-06 (UI):** Provide a native, immediate-mode GUI for visualization (Oscilloscope).
+
+### 2.2 Technical Constraints (TC)
+- **TC-01:** No modifications allowed to the MARTe2 core library or component source code.
+- **TC-02:** Instrumentation must use Runtime Class Registry Patching.
+- **TC-03:** Real-time threads must remain lock-free; use `FastPollingMutexSem` or atomic operations for synchronization.
+- **TC-04:** Telemetry must be delivered via UDP to minimize impact on real-time jitter.
+
+## 3. Performance Metrics
+- **Latency:** Telemetry dispatch overhead < 5 microseconds per signal.
+- **Throughput:** Support for 100Hz+ sampling rates with zero packet loss on local networks.
+- **Scalability:** Handle up to 4096 unique signals and 16 simultaneous client connections.
