+| `tree` | `tree` (object) | Full ORD tree (sent on SSE connect) |
+
+Example trace event:
+```
+event: message
+data: {"type":"trace","name":"App.Data.DDB.Counter","ts":1234567890,"value":42.0}
+
+```
+
+---
+
+## 3. UDP Telemetry Format (DebugService, default port 8081)
+
+Packets are little-endian and packed (`#pragma pack(1)`).
+
+### 3.1 `TraceHeader` (20 bytes)
+
+| Offset | Type | Field | Description |
+|---|---|---|---|
+| 0 | uint32 | `magic` | Always `0xDA7A57AD` |
+| 4 | uint32 | `seq` | Monotonically incrementing sequence number |
+| 8 | uint64 | `timestamp` | High-resolution hardware timestamp |
+| 16 | uint32 | `count` | Number of samples in this datagram |
+
+### 3.2 Sample Entry (per signal)
+
+| Offset | Type | Field | Description |
+|---|---|---|---|
+| 0 | uint32 | `id` | Signal ID from `DISCOVER` |
+| 4 | uint64 | `timestamp` | Per-sample RT timestamp |
+| 12 | uint32 | `size` | Payload size in bytes |
+| 16 | bytes | `data` | Raw signal memory (`size` bytes) |
+
+Multiple samples may be packed into one datagram up to `STREAMER_MTU = 1400` bytes.
+A new datagram is started when the next sample would overflow the MTU.
+
+---
+
+## 4. Log Forwarding (DebugService, default port 8082)
+
+The `TcpLogger` component (`Source/Components/Interfaces/TCPLogger/`) connects to the
+MARTe2 global `LoggerI` and forwards every `REPORT_ERROR` call as a text line:
+
+```
+<level>|<object>|<function>|<message>\n
+```
+
+Up to 8 simultaneous log clients are supported.  If no client is connected, log events
+are silently discarded.
+
+To enable:
+
+```text
++Logger = {
+    Class   = TcpLogger
+    Port    = 8082
+    MaxClients = 8
+}
+```
+
+On `WebDebugService`, logs are forwarded to SSE clients as `{"type":"log","level":"…","msg":"…"}`
+events — no separate `TcpLogger` instance is required.

 # 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.
+
+The MARTe2 Debug Suite is a C++ server library that instruments running MARTe2 applications
+without modifying their source code.  It exposes an abstract `DebugServiceI` interface that
+decouples the broker injection layer from the communication transport, allowing multiple
+transport backends to coexist (currently TCP/UDP and HTTP/SSE).
+

 ## 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).
+The "Zero-Code-Change" requirement is met by intercepting the MARTe2 `ClassRegistryDatabase`.
+When `DebugService` or `WebDebugService` initialises, `PatchRegistry()` replaces the
+`ObjectBuilder` for every standard `MemoryMap*Broker` class in the registry.  When
+`RealTimeApplication::ConfigureApplication()` runs afterward it instantiates wrapped broker
+objects instead of the originals — the application sees no difference.
 
-## 3. Communication Layer
-The system uses three distinct channels:
+Patched broker types:
 
-### 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.
+| Class | Wrapper |
+|---|---|
+| `MemoryMapInputBroker` | `DebugBrokerWrapper<MemoryMapInputBroker>` |
+| `MemoryMapOutputBroker` | `DebugBrokerWrapper<MemoryMapOutputBroker>` |
+| `MemoryMapSynchronisedInputBroker` | `DebugBrokerWrapper<MemoryMapSynchronisedInputBroker>` |
+| `MemoryMapSynchronisedOutputBroker` | `DebugBrokerWrapper<MemoryMapSynchronisedOutputBroker>` |
+| `MemoryMapMultiBufferBroker` | `DebugBrokerWrapper<MemoryMapMultiBufferBroker>` |
+| `MemoryMapMultiBufferOutputBroker` | `DebugBrokerWrapper<MemoryMapMultiBufferOutputBroker>` |
+| `MemoryMapAsynchronousInputBroker` | `DebugBrokerWrapperAsync<MemoryMapAsynchronousInputBroker>` |
+| `MemoryMapAsynchronousOutputBroker` | `DebugBrokerWrapperAsync<MemoryMapAsynchronousOutputBroker>` |
+| `MemoryMapInterpolatedInputBroker` | `DebugBrokerWrapper<MemoryMapInterpolatedInputBroker>` |
+| `MemoryMapStatefulOutputBroker` | `DebugBrokerWrapper<MemoryMapStatefulOutputBroker>` |
+| `MemoryMapStatefulInputBroker` | `DebugBrokerWrapper<MemoryMapStatefulInputBroker>` |
 
-### 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.
-- **Service:** `TcpLogger` (Standalone component).
-- **Role:** Forwards global `REPORT_ERROR` calls and `stdout` messages to the GUI client.

+`Source/Components/Interfaces/DebugService/DebugServiceI.h` defines the abstract singleton
+interface.  It has two logical groups:
+
+### 3.1 RT-path API
+Called from broker threads on every RT cycle.  Must be as cheap as possible; the only
+permissible synchronisation primitive is `FastPollingMutexSem`.
+
+| Method | Purpose |
+|---|---|
+| `RegisterSignal(addr, type, name, …)` | Called once per signal during broker `Init()` |
+| `ProcessSignal(info, size, timestamp)` | Apply forcing, check break, push trace sample |
+| `RegisterBroker(…)` | Cache broker metadata for active/break index updates |
+| `IsPaused() / SetPaused(bool)` | Query / set global pause state |
+| `ConsumeStepIfNeeded(gamName, thread)` | Decrement step counter on output-broker Execute |
+
+### 3.2 Control-path API
+Called from server/command-handler threads; latency acceptable.
+
+| Method | Purpose |
+|---|---|
+| `ForceSignal / UnforceSignal` | Persistent value injection |
+| `TraceSignal(name, enable, decimation)` | Enable/disable ring-buffer tracing |
+| `SetBreak / ClearBreak` | Conditional breakpoints |
+| `IsInstrumented(path, …)` | Query whether a signal is reachable |
+| `RegisterMonitorSignal / UnmonitorSignal` | Slow-rate signal polling |
+
+### 3.3 Static singleton pattern
+
+```cpp
+// Concrete implementation registers itself:
+DebugServiceI::SetInstance(this);          // in Initialise()
+DebugServiceI::SetInstance(NULL_PTR(…));   // in destructor
+
+// Broker wrappers retrieve it (no ORD search on the hot path):
+DebugServiceI *svc = DebugServiceI::GetInstance();
+if (svc != NULL_PTR(DebugServiceI*)) { ... }
+```
+
+Shared data structures (`SignalAlias`, `BrokerInfo`) are also defined in `DebugServiceI.h`
+so both transport implementations can use them without a circular dependency.
+
+---
+
+## 4. Transport Implementations
+
+### 4.1 DebugService (TCP/UDP)
+
+`Source/Components/Interfaces/DebugService/DebugService.h/.cpp`
+
+Runs two `SingleThreadService` threads:
+
+| Thread | Role |
+|---|---|
+| `Server()` | Accepts one TCP client at a time; reads text commands; writes JSON/text responses |
+| `Streamer()` | Drains `TraceRingBuffer`; assembles and sends UDP datagrams; polls monitored signals |
+
+Communication ports (all configurable):
+
+| Port | Protocol | Purpose |
+|---|---|---|
+| `ControlPort` (default 8080) | TCP text | Commands and responses |
+| `UdpPort` (default 8081) | UDP binary | High-speed telemetry (`TraceHeader` + samples) |
+| `LogPort` (default 8082) | TCP stream | Log forwarding via `TcpLogger` sidecar |
+
+### 4.2 WebDebugService (HTTP/SSE)
+
+`Source/Components/Interfaces/WebDebugService/WebDebugService.h/.cpp`
+
+Serves a single HTTP port (default 8090) with an embedded browser UI.  Runs two
+`SingleThreadService` threads:
+
+| Thread | Role |
+|---|---|
+| `HttpServer()` | Accepts TCP connections; routes GET/POST/OPTIONS; upgrades SSE clients |
+| `Streamer()` | Drains `TraceRingBuffer` → SSE events; polls monitored signals; heartbeat |
+
+HTTP endpoints:
+
+| Endpoint | Method | Purpose |
+|---|---|---|
+| `/` | GET | Serves embedded single-page application (HTML/CSS/JS) |
+| `/api/command` | POST | Execute a debug command; returns text response |
+| `/api/events` | GET | Server-Sent Events stream for real-time telemetry (up to 8 clients) |
+
+The embedded web UI (`Source/Components/Interfaces/WebDebugService/WebUI.h`) is a
+self-contained single-page application using Chart.js for real-time signal plots and a
+Catppuccin Mocha dark theme.  No install or server-side tooling required.
+
+---
+
+## 5. Signal Flow
+
+### 5.1 Registration (startup, single-threaded)
+
+```
+ConfigureApplication()
+  └─► DebugBrokerWrapper::Init()
+        └─► DebugBrokerHelper::InitSignals()
+              ├─► DebugServiceI::RegisterSignal()   (canonical name + GAM alias)
+              └─► DebugServiceI::RegisterBroker()
+```
+
+### 5.2 RT loop (hot path, multi-threaded)
+
+```
+RealTimeThread::Execute()
+  └─► DebugBrokerWrapper::Execute()
+        ├─► Base::Execute()                  (data moved in/out of GAM memory)
+        └─► DebugBrokerHelper::Process()
+              ├─► For each active signal:
+              │     └─► DebugServiceI::ProcessSignal()
+              │           ├─► if isForcing: memcpy forcedValue → signal memory
+              │           ├─► if isTracing & decimation fires:
+              │           │     └─► tracePushMutex → TraceRingBuffer::Push()
+              │           └─► if breakOp set: evaluate condition → SetPaused(true)
+              └─► (output brokers only) DebugServiceI::ConsumeStepIfNeeded()
+```
+
+### 5.3 Telemetry delivery
+
+**DebugService (UDP)**
+```
+Streamer thread
+  └─► TraceRingBuffer::Pop()
+        └─► assemble into streamerPacketBuffer (MTU=1400)
+              └─► BasicUDPSocket::Write() → client
+```
+
+**WebDebugService (SSE)**
+```
+Streamer thread
+  └─► TraceRingBuffer::Pop()
+        └─► BroadcastSse("message", {"type":"trace","name":…,"value":…})
+              └─► write "event: message\ndata: {…}\n\n" to each SSE socket
+```
+
+---
+
+## 6. TraceRingBuffer
+
+Single-producer / single-consumer circular byte buffer defined in `DebugCore.h`.
+
+```
+Buffer layout per entry: [ID:4][Timestamp:8][Size:4][Data:N]
+```
+
+- `Push()` is serialised by `tracePushMutex` (multiple RT threads write; one Streamer reads).
+- `Pop()` is called exclusively by the Streamer thread.
+- Ring is initialised to 4 MB in both transport implementations.
+- On corrupt `size` field (`size >= bufferSize`): discards all entries to prevent cascading
+  bad reads (Fix #5).
+
+---
+
+## 7. Performance Hardening
+
+The following fixes were applied after initial implementation to improve correctness and
+real-time safety.
+
+| Fix | Area | Change |
+|---|---|---|
+| **#1** | UDP streamer | Named constants `STREAMER_MTU = 1400` and `STREAMER_BUFFER_SIZE = 4096`; removed magic numbers |
+| **#2** | Multi-producer ring | `tracePushMutex` serialises `TraceRingBuffer::Push()` from concurrent RT threads |
+| **#3** | Break evaluation | Break indices copied to stack-local array while holding `activeMutex`; condition evaluated outside the lock |
+| **#4** | Decimation counter | `Atomic::Add` used for lock-free per-signal decimation in multi-producer `ProcessSignal` |
+| **#5** | Ring corruption | `Pop()` skips only the current corrupt entry; falls back to full discard only when `size >= bufferSize` |
+| **#6** | TCP rate limit | Server disconnects clients sending > 100 commands/second (`CMD_RATE_LIMIT = 100`) |
+| **#7** | Broker index swap | `Vec::Swap` inside spinlock followed by free outside; avoids holding the lock during deallocation |
+| **#8** | Idle timeout | Active TCP client disconnected after 30 s of silence (`CLIENT_IDLE_TIMEOUT_MS = 30000`) |
+| **#9** | VALUE output size | `GetSignalValue` caps output at 256 elements (`GET_VALUE_MAX_ELEMENTS`); includes `"Truncated"` flag |
+| **#10** | TCP framing | `inputBuffer` accumulates partial commands across `Read()` calls; bounded at 8 KiB (`INPUT_BUFFER_MAX`) |
+| **#11** | CDB cursor | `Initialise()` never calls `MoveToRoot()` on the CDB passed by the framework; avoids corrupting `ReferenceContainer` traversal |

 # Demo Walkthrough: High-Speed Tracing
 
-This demo demonstrates tracing a `Timer.Counter` signal at 100Hz and verifying its consistency.
+This demo traces a `Timer.Counter` signal at 100 Hz, tests execution control, and verifies
+signal forcing.  It works with either transport — choose the option that matches your setup.
+
+---
+
+## 1. Build and Launch the Test Environment
 
-### 1. Launch the Test Environment
-Start the validation environment which simulates a real-time app:
 ```bash
-./Build/Test/Integration/ValidationTest
+source env.sh
+make -f Makefile.gcc
+./Build/x86-linux/Test/Integration/IntegrationTests
 ```
-*Note: The test will wait for a trace command before finishing.*
 
-### 2. Connect the GUI
-In another terminal:
+The integration test starts a MARTe2 application with `DebugService` or `WebDebugService`
+already configured and waits for client interaction.
+
+---
+
+## 2. Connect a Client
+
+### Option A — Web Browser (`WebDebugService`)
+
+Open `http://localhost:8090` in any browser.  The UI appears instantly with the live
+object tree already loaded.
+
+### Option B — Rust GUI (`DebugService`)
+
 ```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.
+## 3. Explore the Tree
 
-### 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.
+1. In the **Application Tree**, expand `Root → App → Data → Timer`.
+2. Click **Info** (web UI) or **ℹ Info** (Rust GUI) on the `Timer` node.
+3. Verify the config panel shows `SleepTime: 10000` (100 Hz cycle).
+
+---
+
+## 4. Activate Trace
+
+1. Locate the `Counter` signal under `Timer`.
+2. Click **Trace** (web UI) or **📈 Trace** (Rust GUI).
+3. The real-time plot begins with a monotonically increasing counter.
+4. Confirm telemetry is flowing:
+   - **Web UI:** `{"type":"trace",…}` events appear in the browser DevTools Network tab.
+   - **Rust GUI:** The **UDP Packets** counter in the top bar increments rapidly.
+
+---
+
+## 5. Test Execution Control
+
+1. Click **Pause** (⏸).
+2. Observe that the plot freezes and the counter holds steady.
+3. Click **Step** with count = 5.
+4. The counter advances exactly 5 units then stops.
+5. Click **Resume** (▶) to continue normal execution.
+
+---
+
+## 6. Test Signal Forcing
+
+1. Locate `Root.App.Data.DDB.Counter`.
+2. Click **Force** and enter `99999`.
+3. Observe the oscilloscope plot jump to and hold at `99999`.
+4. Click **Unforce** to release — the counter resumes its normal value.
+
+---
+
+## 7. Test a Breakpoint
+
+1. Click **Break** on `Root.App.Data.DDB.Counter`.
+2. Set operator `>` and threshold `500`.
+3. Wait for the counter to exceed 500 — the application pauses automatically.
+4. The status shows **PAUSED** at the GAM that triggered the break.
+5. Click **Break OFF** then **Resume** to continue.

 }
 ```
-The suite automatically patches the registry to instrument your existing Brokers and Schedulers.
+
+---
+
+## Features
+
+| Feature | Description |
+|---|---|
+| **Zero-code-change** | Registry patching replaces standard brokers at runtime — no application changes needed |
+| **Signal tracing** | Stream any signal at full RT rate over UDP (DebugService) or SSE (WebDebugService) |
+| **Signal forcing** | Persistent value injection directly into the RT memory map |
+| **Breakpoints** | Halt execution when a signal crosses a threshold (`> < == >= <= !=`) |
+| **Execution stepping** | Step N RT cycles then pause; optionally filter by thread |
+| **Live object tree** | Browse the full `ObjectRegistryDatabase` hierarchy with signal metadata |
+| **Config serving** | Retrieve the complete application CDB as JSON |
+| **Log forwarding** | All `REPORT_ERROR` events forwarded to the client in real time |
+| **Signal monitoring** | Poll any `DataSourceI` signal at a configurable period |
+| **MARTe2 messaging** | Send `Message` objects to any ORD object from the debug client |
+
+---
+
+## Transports at a Glance
+
+| | `DebugService` | `WebDebugService` |
+|---|---|---|
+| **Client** | Rust native GUI or any TCP tool | Any web browser |
+| **Commands** | Text over TCP (port 8080) | HTTP POST `/api/command` |
+| **Telemetry** | Binary UDP (port 8081) | Server-Sent Events `/api/events` |
+| **Logs** | TcpLogger TCP (port 8082) | SSE event stream |
+| **Install** | Rust + Cargo | None |
+
+Both transports implement the same `DebugServiceI` interface and register themselves as the global singleton — they are mutually exclusive (one per application).

 # MARTe2 Debug Suite Specifications
 
-**Version:** 1.2  
+**Version:** 2.0
 **Status:** Active / Implemented
 
+---
+
 ## 1. Executive Summary
-This project implements a "Zero-Code-Change" observability and debugging layer for the MARTe2 real-time framework. The system allows developers to Trace, Force, and Monitor any signal in a running MARTe2 application without modifying existing source code.
+
+This project implements a "Zero-Code-Change" observability and debugging layer for the
+MARTe2 real-time framework.  Developers can trace, force, and monitor any signal in a
+running MARTe2 application without modifying existing source code.
+
+The suite ships two interchangeable transport backends sharing a common abstract interface:
+
+- **`DebugService`** — TCP command channel + binary UDP telemetry + `TcpLogger` sidecar.
+  Paired with a native Rust/egui GUI.
+- **`WebDebugService`** — HTTP command endpoint + Server-Sent Events telemetry, with an
+  embedded single-page browser UI. No additional client software required.
+
+---
 
 ## 2. System Architecture
-- **The Universal Debug Service (C++ Core):** A singleton MARTe2 Object that patches the registry and manages communication.
-- **The Broker Injection Layer (C++ Templates):** Templated wrappers that intercept `Execute()` and `Init()` calls for tracing, forcing, and execution control.
-- **The Remote Analyser (Rust/egui):** A high-performance, multi-threaded GUI for visualization and control.
-- **Network Stack:**
-    - **Port 8080 (TCP):** Commands and Metadata.
-    - **Port 8081 (UDP):** High-Speed Telemetry for Oscilloscope.
-    - **Port 8082 (TCP):** Independent Real-Time Log Stream via `TcpLogger`.
+
+- **`DebugServiceI` (Abstract Interface):** Singleton that decouples the broker injection
+  layer from the transport.  Defined in `DebugServiceI.h`.
+- **`DebugService` (TCP/UDP Transport):** TCP text command channel (port 8080), binary UDP
+  telemetry (port 8081), `TcpLogger` log sidecar (port 8082).
+- **`WebDebugService` (HTTP/SSE Transport):** Single HTTP port (default 8090) serving the
+  embedded web UI, command API, and SSE telemetry stream.
+- **`DebugBrokerWrapper` (Injection Layer):** C++ template wrappers injected via registry
+  patching.  Depend only on `DebugServiceI`; transport-agnostic.
+- **`TcpLogger` (Log Sidecar):** Optional standalone component forwarding `REPORT_ERROR`
+  events to TCP clients on a dedicated port (used with `DebugService` only).
+
+---
 
 ## 3. Requirements
 
 ### 3.1 Functional Requirements (FR)
-- **FR-01 (Discovery):** Discover the full MARTe2 object hierarchy at runtime. The GUI client SHALL request the full application tree upon connection and display it in a hierarchical tree view.
-- **FR-02 (Telemetry):** Stream high-frequency signal data (verified up to 100Hz+) to a remote client via UDP.
+
+- **FR-01 (Discovery):** Discover the full MARTe2 object hierarchy at runtime.  The client
+  SHALL request the full application tree and display it hierarchically.
+- **FR-02 (Telemetry):** Stream high-frequency signal data (verified > 100 Hz) to a remote
+  client.  `DebugService` uses binary UDP; `WebDebugService` uses SSE.
 - **FR-03 (Forcing):** Allow manual override of signal values in memory during execution.
-- **FR-04 (Logs):** Stream global framework logs to a dedicated terminal/client via a standalone `TcpLogger` service.
-- **FR-05 (Log Filtering):** The client must support filtering logs by type (Debug, Information, Warning, FatalError) and by content using regular expressions.
-- **FR-06 (Execution Control):** Provide a mechanism to pause and resume the execution of all patched real-time threads (via Brokers), allowing for static inspection of the system state.
-- **FR-07 (Session Management):** Support runtime re-configuration and "Apply & Reconnect" logic. The GUI provides a "Disconnect" button to close active network streams.
-- **FR-08 (Decoupled Tracing):** Tracing activates telemetry; data is buffered and shown as a "Last Value" in the sidebar, but not plotted until manually assigned.
-- **FR-09 (Advanced Plotting):** 
-    - Support multiple plot panels with perfectly synchronized time (X) axes.
-    - Drag-and-drop signals from the traced list into specific plots.
-    - Plot modes: Standard (Time Series) and Logic Analyzer (Stacked rows).
-    - Signal transformations: Gain, offset, units, and custom labels.
-- **FR-10 (Navigation & Scope):** 
-    - Context menus for resetting zoom (X, Y, or both).
-    - "Fit to View" functionality that automatically scales both axes.
-    - High-performance oscilloscope mode with configurable time windows (10ms to 10s).
-    - Triggered acquisition (Single/Continuous, rising/falling edges).
-- **FR-11 (Data Recording):** Record any traced signal to disk in Parquet format with a visual recording indicator in the GUI.
-- **FR-12 (Configuration Awareness):** The DebugService SHALL store a complete copy of the application's configuration provided at initialization.
-- **FR-13 (Metadata Enrichment):** Metadata returned by `INFO` and `DISCOVER` SHALL be enriched with additional fields from the stored configuration (e.g., Frequency, PVNames, Units).
-- **FR-14 (Configuration Serving):** Provide a `CONFIG` command to serve the full stored configuration in JSON format to the client.
+  The override SHALL persist across RT cycles until explicitly released.
+- **FR-04 (Logs):** Forward all `REPORT_ERROR` events to a connected client in real time.
+  `DebugService` uses `TcpLogger` on a dedicated TCP port.  `WebDebugService` embeds logs
+  in the SSE stream.
+- **FR-05 (Log Filtering):** The client SHOULD support filtering log output by level and
+  by content.
+- **FR-06 (Execution Control):** Provide pause and resume for all patched RT threads,
+  allowing static inspection of the system state.
+- **FR-07 (Breakpoints):** Halt execution when a signal crosses a threshold.  Supported
+  operators: `>`, `<`, `==`, `>=`, `<=`, `!=`.
+- **FR-08 (Execution Stepping):** After a pause or breakpoint, allow resuming for exactly
+  N output-broker cycles then pausing again.  Optional per-thread filter.
+- **FR-09 (Decoupled Tracing):** Activating a trace SHALL only stream data; displaying
+  the data (plot, sidebar) is the client's responsibility.
+- **FR-10 (Signal Monitoring):** Poll any `DataSourceI` signal at a configurable period
+  without requiring that signal to be traced at full RT rate.
+- **FR-11 (Config Awareness):** The service SHALL accept and store a full copy of the
+  application's CDB (`SetFullConfig`).  `INFO` and `DISCOVER` responses SHALL be enriched
+  with additional metadata fields from this CDB.
+- **FR-12 (Config Serving):** Provide a `CONFIG` command returning the full stored
+  configuration as JSON.
+- **FR-13 (MARTe2 Messaging):** Allow sending `Message` objects to any ORD object via an
+  `MSG` command.
+- **FR-14 (Dual Transport):** Both `DebugService` and `WebDebugService` SHALL implement
+  the identical `DebugServiceI` interface and be mutually exclusive singletons.  Switching
+  transport SHALL require only a config change (different class name, different port).
+- **FR-15 (Embedded Web UI):** `WebDebugService` SHALL serve a self-contained single-page
+  application with real-time plotting (Chart.js), signal tree, force/break/monitor dialogs,
+  and an integrated log viewer — without any external server or build tooling.
 
 ### 3.2 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.
+- **TC-02:** Instrumentation MUST use runtime class registry patching (`ClassRegistryDatabase`).
+- **TC-03:** RT-path methods (`ProcessSignal`, `IsPaused`) MUST be lock-free or use only
+  `FastPollingMutexSem`; no heap allocation on the RT path.
+- **TC-04:** `DebugService` telemetry MUST use UDP to minimise jitter impact.
+- **TC-05:** No STL — use `Vec<T>` and `StreamString` throughout.
+- **TC-06:** C++98 compatibility for all source files (no `auto`, no range-for, no raw
+  string literals).
+- **TC-07:** The `DebugServiceI` abstract interface MUST be the only dependency of
+  `DebugBrokerWrapper`.  Concrete transport headers MUST NOT be included by broker code.
 
-## 4. 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.
-- **Code Quality:** Maintain a minimum of **85% code coverage** across all core service and broker logic.
+---
 
-## 5. Communication Protocol (Port 8080)

-- **FORCE <Signal> <Value>:** Persistent signal override.
-- **UNFORCE <Signal>:** Remove override.
-- **LOG <Level> <Msg>:** Streaming format used on Port 8082.
+## 4. Performance Requirements
+
+- **Latency:** `ProcessSignal` overhead < 5 µs per signal when tracing is inactive.
+- **Throughput:** Support > 100 Hz signal tracing with zero sample loss on local networks
+  (UDP transport).
+- **Scalability:** Handle up to 4096 unique signals.
+- **Ring buffer size:** `TraceRingBuffer` initialised to 4 MB in both transports.
+- **SSE clients:** `WebDebugService` supports up to 8 simultaneous SSE clients.
+- **TCP rate limit:** Server disconnects clients sending > 100 commands/s.
+- **VALUE output cap:** `GetSignalValue` returns at most 256 elements per call.

+
+## 5. Performance Hardening Log
+
+| Fix | Category | Description |
+|---|---|---|
+| **#1** | Naming | `STREAMER_MTU = 1400`, `STREAMER_BUFFER_SIZE = 4096` replace magic numbers |
+| **#2** | Concurrency | `tracePushMutex` serialises multi-producer `TraceRingBuffer::Push()` |
+| **#3** | Concurrency | Break indices copied under `activeMutex`; condition evaluated outside lock |
+| **#4** | Concurrency | `Atomic::Add` for lock-free per-signal decimation counter |
+| **#5** | Robustness | `TraceRingBuffer::Pop` skips corrupt entry; full discard only when unrecoverable |
+| **#6** | Security | TCP command rate-limit: > 100 cmd/s → client disconnect |
+| **#7** | Latency | `Vec::Swap` inside spinlock; deallocation outside — shorter lock hold time |
+| **#8** | Robustness | 30-second idle timeout on active TCP client |
+| **#9** | Safety | `VALUE` output capped at 256 elements; `"truncated":true` flag included |
+| **#10** | Correctness | `inputBuffer` reassembles split TCP commands; bounded at 8 KiB |
+| **#11** | Correctness | `Initialise()` never calls `MoveToRoot()` on the framework-supplied CDB |

+ *   Control-path API
+ *     Called from server / command-handler threads (TCP, TTY, Web …).
+ *     Latency here is acceptable; correctness and thread-safety matter.

-# Tutorial: High-Speed Observability with MARTe2 Debug GUI
+# Tutorial: Observability and Debugging with the MARTe2 Debug Suite
 
-This guide will walk you through the process of tracing and forcing signals in a real-time MARTe2 application using the native Rust GUI client.
+This guide covers both transport options.  Choose the one that fits your workflow:
 
-## 1. Environment Setup
+| | `WebDebugService` | `DebugService` |
+|---|---|---|
+| **Client** | Any web browser | Rust native GUI |
+| **Setup** | Config only | Config + `cargo run` |
+| **Best for** | Quick inspection, remote access | High-performance plots, scripted tooling |
+
+---
+
+## Part A — Web UI (`WebDebugService`)
+
+### A.1 Environment Setup
 
-### Launch the MARTe2 Application
-First, start your application using the provided debug runner. This script launches the standard `MARTeApp.ex` while injecting the debugging layer:
 ```bash
-./run_debug_app.sh
+cd /path/to/your/marte2/project
+source /path/to/marte_debug/env.sh
 ```
-*Note: You should see logs indicating the `DebugService` has started on port 8080 and `TcpLogger` on port 8082.*
 
-### Start the GUI Client
-In a new terminal window, navigate to the client directory and run the GUI:
+### A.2 Add `WebDebugService` to Your Config
+
+Add the service as a **sibling** of the `+App` node (not inside it):
+
+```text
++WebDebugService = {
+    Class    = WebDebugService
+    HttpPort = 8090
+}
+
++App = {
+    Class = RealTimeApplication
+    ...
+}
+```
+
+Restart your application.  You should see:
+```
+[WebDebugService] HTTP server listening on port 8090
+```
+
+### A.3 Open the Web UI
+
+Navigate to `http://localhost:8090` in any browser.  The UI connects automatically via SSE.
+
+---
+
+### A.4 Exploring the Object Tree
+
+The **Application Tree** panel on the left mirrors your live ORD hierarchy.
+
+1. Expand `Root → App → Data` to find data sources.
+2. Click **Info** next to any node to see its class, config, and signals in the details panel.
+3. Click **List** to expand just the immediate children without recursing.
+
+---
+
+### A.5 Real-Time Signal Tracing
+
+1. Locate a signal in the tree, e.g. `Root.App.Data.Timer.Counter`.
+2. Click **Trace** next to the signal.  The signal appears in the **Traced Signals** list with
+   its live last value.
+3. Click **Plot** to open it in the real-time Chart.js graph.  Use the **Follow** toggle to
+   keep the time axis scrolling.
+4. To set the sampling decimation (e.g. every 10th sample), use the command box at the bottom
+   of the page:
+   ```
+   TRACE App.Data.Timer.Counter 1 10
+   ```
+5. Click **Trace** again (or send `TRACE … 0`) to stop.
+
+---
+
+### A.6 Signal Forcing
+
+1. Find a GAM output signal, e.g. `Root.App.Data.DDB.Counter`.
+2. Click **Force**.  A modal dialog appears.
+3. Enter a value (e.g. `9999`) and click **Apply**.
+4. The signal is locked at that value every RT cycle.
+5. Click **Unforce** (or use the **Active Controls** panel) to release.
+
+---
+
+### A.7 Breakpoints
+
+1. Click **Break** next to a signal.
+2. Select an operator (`>`, `<`, `==`, etc.) and enter a threshold.
+3. When the condition fires, the application pauses automatically.  The status bar shows
+   **PAUSED** and the GAM name where execution stopped.
+4. Use **Step** to advance one cycle at a time, or **Resume** to continue.
+5. Click **Break OFF** to clear the breakpoint.
+
+---
+
+### A.8 Execution Stepping
+
+While paused (after a breakpoint or manual **Pause**):
+
+1. Enter a step count in the **Step** box (e.g. `5`) and click **Step**.
+2. The RT loop runs exactly 5 output-broker cycles, then pauses again.
+3. The status SSE event (`{"type":"status","remaining":…}`) keeps the UI updated.
+
+---
+
+### A.9 Signal Monitoring
+
+Monitoring polls a signal at a slow rate without using the RT trace path — useful for
+`DataSourceI` signals not connected to any GAM.
+
+1. Click **Monitor** next to a signal.
+2. Enter a poll period in milliseconds (e.g. `500`).
+3. The signal's current value arrives via SSE every 500 ms as a `{"type":"monitor",…}` event.
+
+---
+
+### A.10 Log Viewer
+
+The **Logs** panel at the bottom shows every `REPORT_ERROR` call forwarded as SSE events.
+Use the level buttons (D / I / W / E) to filter by severity, or type a keyword to search.
+
+---
+
+## Part B — Rust Native GUI (`DebugService`)
+
+### B.1 Environment Setup
+
+```bash
+source /path/to/marte_debug/env.sh
+```
+
+### B.2 Add `DebugService` to Your Config
+
+```text
++DebugService = {
+    Class       = DebugService
+    ControlPort = 8080
+    UdpPort     = 8081
+    LogPort     = 8082
+}
+
++App = {
+    Class = RealTimeApplication
+    ...
+}
+```
+
+### B.3 Start the GUI Client
+
 ```bash
 cd Tools/gui_client
 cargo run --release
 ```
 
-## 2. Exploring the Object Tree
-Once connected, the left panel (**Application Tree**) displays the live hierarchy of your application.
+The GUI connects to `localhost:8080` automatically and requests the tree on startup.
 
-1.  **Navigate to Data:** Expand `Root` -> `App` -> `Data`.
-2.  **Inspect Nodes:** Click the **ℹ Info** button next to any node (like `Timer` or `DDB`). 
-3.  **View Metadata:** The bottom-left pane will display the full JSON configuration of that object, including its class, parameters, and signals.
+---
 
-## 3. Real-Time Signal Tracing (Oscilloscope)
-Tracing allows you to see signal values exactly as they exist in the real-time memory map.
+### B.4 Exploring the Object Tree
 
-1.  **Find a Signal:** In the tree, locate `Root.App.Data.Timer.Counter`.
-2.  **Activate Trace:** Click the **📈 Trace** button.
-3.  **Monitor the Scope:** The central **Oscilloscope** panel will begin plotting the signal. 
-4.  **Verify Data Flow:** Check the **UDP Packets** counter in the top bar; it should be increasing rapidly, confirming high-speed data reception (Port 8081).
-5.  **Multi-Signal Trace:** You can click **📈 Trace** on other signals (like `Time`) to overlay multiple plots.
+The **Application Tree** panel on the left shows the live ORD.
 
-## 4. Signal Forcing (Manual Override)
-Forcing allows you to bypass the framework logic and manually set a signal's value in memory.
+1. Expand `Root → App → Data`.
+2. Click **ℹ Info** next to any node to see its JSON config in the bottom-left pane.
 
-1.  **Locate Target:** Find a signal that is being written by a GAM, such as `Root.App.Data.DDB.Counter`.
-2.  **Open Force Dialog:** Click the **⚡ Force** button next to the signal.
-3.  **Inject Value:** In the popup dialog, enter a new value (e.g., `9999`) and click **Apply Force**.
-4.  **Observe Effect:** If you are tracing the same signal, the oscilloscope plot will immediately jump to and hold at `9999`.
-5.  **Release Control:** To stop forcing, click the **❌** button in the **Active Controls** (Right Panel) under "Forced Signals". The framework will resume writing its own values to that memory location.
+---
 
-## 5. Advanced Controls
+### B.5 Real-Time Signal Tracing (Oscilloscope)
 
-### Global Pause
-If you need to "freeze" the entire application to inspect a specific state:
-- Click **⏸ Pause** in the top bar. The real-time threads will halt at the start of their next cycle.
-- Click **▶ Resume** to restart the execution.
+1. Locate `Root.App.Data.Timer.Counter`.
+2. Click **📈 Trace**.  The **Oscilloscope** panel begins plotting.
+3. The **UDP Packets** counter in the top bar increments — confirming high-speed telemetry
+   on port 8081.
+4. Drag additional signals from the **Traced Signals** list into the oscilloscope panel for
+   multi-signal overlay.
 
-### Log Terminal
-The bottom panel displays every `REPORT_ERROR` event from the C++ framework, powered by the standalone `TcpLogger` service.
-- **Regex Filter:** Type a keyword like `Timer` in the filter box to isolate relevant events.
-- **Pause Logs:** Toggle **⏸ Pause Logs** to stop the scrolling view while data continues to be captured in the background.
+---
+
+### B.6 Signal Forcing
+
+1. Find `Root.App.Data.DDB.Counter`.
+2. Click **⚡ Force**.
+3. Enter a value (e.g. `9999`) and click **Apply Force**.
+4. The oscilloscope plot immediately jumps to and holds at `9999`.
+5. Click **❌** in the **Active Controls** panel to release the force.
+
+---
+
+### B.7 Global Pause and Resume
+
+- Click **⏸ Pause** in the top bar to halt all RT threads.
+- Click **▶ Resume** to continue.
+
+---
+
+### B.8 Log Terminal
+
+The bottom panel shows all `REPORT_ERROR` events forwarded from `TcpLogger` (port 8082).
+
+- **Regex Filter:** Type a keyword (e.g. `Timer`) to isolate events.
+- **⏸ Pause Logs:** Stop scrolling while continuing to capture.
+
+---
+
+## Part C — Scripted / Programmatic Access
+
+Both transports accept plain text commands.  You can use `nc` or any TCP client:
+
+```bash
+# DebugService
+echo -e "DISCOVER\nTRACE App.Data.DDB.Counter 1" | nc localhost 8080
+
+# WebDebugService
+curl -s -X POST http://localhost:8090/api/command \
+     -H "Content-Type: text/plain" \
+     -d "DISCOVER"
+```
+
+For the full command reference see [API.md](API.md).
