Subject: [PATCH 1/6] refactor: Begin modular architecture and restore TODO

This commit introduces the core infrastructure for a new modular,
message-based architecture and restores the project's TODO list.

- A new `message_bus` component provides a global FreeRTOS queue for
  inter-task communication.
- The `bus_manager_task` is replaced by a new `servo_controller_task`
  that uses the message bus.
- `app_main` is updated to initialize the new components.
- The `TODO.md` file has been restored by merging the previous project
  roadmap with the new detailed plan for the architectural refactoring.

-## Phase 3: Future Enhancements (Not Started)
+## Phase 3: Architectural Refactoring (Inspired by Hexabitz BOS)
+
+The goal of this phase is to refactor the current monolithic application into a modular, message-based architecture. This will improve scalability, testability, and enable a true multi-MCU wired-mesh network in the future, fulfilling the goals of the original Phase 2 "Inter-ESP32 Communication" task in a more structured way.
+
+### 3.1: Core Infrastructure - The Message Bus
+-   [ ] **Create `message_bus.h`:**
+    -   Define the `message_type_t` enum with all message types (`MSG_SET_SERVO_POS`, `MSG_GET_ALL_SENSOR_DATA`, `MSG_REFLEX_VECTOR`, etc.).
+    -   Define the generic `message_t` struct, including source/target module IDs, payload, and an optional response queue.
+    -   Declare the global message bus queue handle: `extern QueueHandle_t g_message_bus;`.
+-   [ ] **Create `message_bus.c`:**
+    -   Define and create the global `g_message_bus` FreeRTOS queue.
+    -   Implement a `message_bus_init()` function.
+-   [ ] **Update `app_main`:**
+    -   Call `message_bus_init()` during startup.
+    -   Remove the old, separate `g_bus_request_queues`.
+
+### 3.2: Modularize Servo Control
+-   [ ] **Create `servo_controller.c/h`:**
+    -   Implement a `servo_controller_task` that replaces the old `bus_manager_task`.
+    -   This task will loop, waiting for messages on the `g_message_bus`.
+    -   It will contain a `switch` statement to handle servo-related messages (`MSG_SET_SERVO_POS`, `MSG_GET_SERVO_POS`, etc.).
+    -   The handlers will call the low-level `feetech_*` protocol functions.
+-   [ ] **Update `app_main`:**
+    -   Create the `servo_controller_task`.
+    -   Remove the creation of the old `bus_manager_task`.
+
+### 3.3: Unify Control into a Master Controller
+-   [ ] **Create `master_controller.c/h`:**
+    -   Implement a `master_controller_task`.
+    -   Move the console initialization logic from `console.c` into this task.
+    -   Move the MCP server initialization and task logic from `mcp_server.c` into this task.
+-   [ ] **Refactor Command Handlers:**
+    -   Modify the console command functions (`cmd_*`) to no longer call business logic directly.
+    -   Instead, they will parse user input, create the appropriate `message_t` struct, and send it to the `g_message_bus`.
+    -   Modify the MCP server's `handle_call_tool` function to do the same for incoming JSON commands.
+-   [ ] **Update `app_main`:**
+    -   Create the `master_controller_task`.
+    -   Remove the old `console_task` creation and the `mcp_server_init()` call.
+
+### 3.4: Modularize Core Brain Functions
+-   [ ] **Create separate modules for `learning`, `behavior`, and `reflexes`:**
+    -   Move the `learning_loop_task` to a new `learning_core.c` file.
+    -   Move the `behavior_task` to a new `behavior_engine.c` file.
+    -   Create a new `reflex_engine_task` in `reflex_engine.c`.
+-   [ ] **Refactor tasks to use the message bus:**
+    -   Modify all three tasks to communicate with other modules exclusively via the `g_message_bus`.
+    -   For example, to get sensor data, the `learning_loop_task` will now send a `MSG_GET_ALL_SENSOR_DATA` message instead of calling a function directly. To execute a move, it will send a `MSG_SET_SERVO_POS` message.
+-   [ ] **Create a dedicated Sensor Manager:**
+    -   Create a new `sensor_manager.c/h` module and `sensor_manager_task`.
+    -   This task will be responsible for all direct communication with sensor drivers (BMA400, Synsense).
+    -   It will listen for sensor data requests on the message bus and send back responses containing the data.
+
+### 3.5: Implement and Demonstrate the "Reflex" Path
+-   [ ] **Add `reflex_inject` console command:**
+    -   Add the new command to the `master_controller.c`.
+    -   This command will parse a vector from the command line.
+-   [ ] **Implement the reflex message:**
+    -   The `reflex_inject` command handler will create a `MSG_REFLEX_VECTOR` message containing the parsed vector and send it to the message bus, targeted at the `reflex_engine` module.
+-   [ ] **Implement the Reflex Engine logic:**
+    -   The `reflex_engine_task` will receive the `MSG_REFLEX_VECTOR` message.
+    -   It will perform a direct forward pass of the neural network using the vector data.
+    -   It will then send the resulting action vector as a command message to the `servo_controller` module.
+
+## Phase 4: Future Enhancements (Not Started)
 
 *   **[TODO] Advanced Clustering:** Upgrade the training pipeline from K-Means to a Self-Organizing Map (SOM) for a more topologically meaningful gesture map.
 *   **[TODO] Real-time Obstacle Avoidance:** Integrate distance sensors (e.g., IR, Ultrasonic) into the planner's cost function to enable dynamic obstacle avoidance.
 *   **[TODO] Higher-Level Behavior Tree:** Implement a formal behavior tree on a host PC that can sequence complex, multi-step tasks by sending goal sequences to the robot.
 *   **[TODO] Vision System Integration:** Add a camera and a vision processing pipeline (e.g., on the host PC) to enable object detection and visual servoing.
-
 *   **[DONE] Sub-task: Implement Python-based Vision Processing**
     *   **Description:** Implement a Python script to configure the Synsense Speck camera for a specific task (e.g., edge detection) and read the output. This approach leverages the high-level `samna` and `sinabs` libraries, removing the need for a low-level C driver.
-    *   **Status:** An `edge_detector.py` script has been created, which defines an SNN model, configures the chip, and includes a loop for real-time inference.
+    *   **Status:** An `edge_detector.py` script has been created, which defines an SNN model, aget_corrected_position_pynd configures the chip, and includes a loop for real-time inference.
+*   **[TODO] Coordinated Motion:** The ultimate goal of this phase. This involves deep integration between the two subsystems.
+    *   **Next Steps:**
+        *   **Offline:** Train a new, larger neural network on data from both the arm and base to create a **combined embedding space**.
+        *   **Online:** Implement a distributed planning system where a "master" ESP32 can send coordinated goal embeddings to the "slave" to perform complex tasks (e.g., moving while manipulating an object).

Subject: [PATCH 2/6] refactor: Implement message bus and servo controller
 module

This commit introduces the core infrastructure for a new modular,
message-based architecture.

- A new `message_bus` component has been added, which defines a global
  FreeRTOS queue (`g_message_bus`) for inter-task communication.
- The old `bus_manager_task` is replaced by a new
  `servo_controller_task` that processes servo commands received from
  the message bus.
- The `initialize_robot_arm` function is refactored to send
  messages to the new servo controller via the message bus.
- Other functions that still use the old queue system are temporarily
  disabled until they can be refactored.

-
-The goal of this phase is to refactor the current monolithic application into a modular, message-based architecture. This will improve scalability, testability, and enable a true multi-MCU wired-mesh network in the future, fulfilling the goals of the original Phase 2 "Inter-ESP32 Communication" task in a more structured way.

-    -   Define the `message_type_t` enum with all message types (`MSG_SET_SERVO_POS`, `MSG_GET_ALL_SENSOR_DATA`, `MSG_REFLEX_VECTOR`, etc.).
-    -   Define the generic `message_t` struct, including source/target module IDs, payload, and an optional response queue.
-    -   Declare the global message bus queue handle: `extern QueueHandle_t g_message_bus;`.
--   [ ] **Create `message_bus.c`:**
-    -   Define and create the global `g_message_bus` FreeRTOS queue.
-    -   Implement a `message_bus_init()` function.
--   [ ] **Update `app_main`:**
-    -   Call `message_bus_init()` during startup.
-    -   Remove the old, separate `g_bus_request_queues`.
-
-### 3.2: Modularize Servo Control
--   [ ] **Create `servo_controller.c/h`:**
-    -   Implement a `servo_controller_task` that replaces the old `bus_manager_task`.
-    -   This task will loop, waiting for messages on the `g_message_bus`.
-    -   It will contain a `switch` statement to handle servo-related messages (`MSG_SET_SERVO_POS`, `MSG_GET_SERVO_POS`, etc.).
-    -   The handlers will call the low-level `feetech_*` protocol functions.
--   [ ] **Update `app_main`:**
-    -   Create the `servo_controller_task`.
-    -   Remove the creation of the old `bus_manager_task`.
-
-### 3.3: Unify Control into a Master Controller
--   [ ] **Create `master_controller.c/h`:**
-    -   Implement a `master_controller_task`.
-    -   Move the console initialization logic from `console.c` into this task.
-    -   Move the MCP server initialization and task logic from `mcp_server.c` into this task.
--   [ ] **Refactor Command Handlers:**
-    -   Modify the console command functions (`cmd_*`) to no longer call business logic directly.
-    -   Instead, they will parse user input, create the appropriate `message_t` struct, and send it to the `g_message_bus`.
-    -   Modify the MCP server's `handle_call_tool` function to do the same for incoming JSON commands.
--   [ ] **Update `app_main`:**
-    -   Create the `master_controller_task`.
-    -   Remove the old `console_task` creation and the `mcp_server_init()` call.
-
-### 3.4: Modularize Core Brain Functions
--   [ ] **Create separate modules for `learning`, `behavior`, and `reflexes`:**
-    -   Move the `learning_loop_task` to a new `learning_core.c` file.
-    -   Move the `behavior_task` to a new `behavior_engine.c` file.
-    -   Create a new `reflex_engine_task` in `reflex_engine.c`.
--   [ ] **Refactor tasks to use the message bus:**
-    -   Modify all three tasks to communicate with other modules exclusively via the `g_message_bus`.
-    -   For example, to get sensor data, the `learning_loop_task` will now send a `MSG_GET_ALL_SENSOR_DATA` message instead of calling a function directly. To execute a move, it will send a `MSG_SET_SERVO_POS` message.
--   [ ] **Create a dedicated Sensor Manager:**
-    -   Create a new `sensor_manager.c/h` module and `sensor_manager_task`.
-    -   This task will be responsible for all direct communication with sensor drivers (BMA400, Synsense).
-    -   It will listen for sensor data requests on the message bus and send back responses containing the data.
-
-### 3.5: Implement and Demonstrate the "Reflex" Path
--   [ ] **Add `reflex_inject` console command:**
-    -   Add the new command to the `master_controller.c`.
-    -   This command will parse a vector from the command line.
--   [ ] **Implement the reflex message:**
-    -   The `reflex_inject` command handler will create a `MSG_REFLEX_VECTOR` message containing the parsed vector and send it to the message bus, targeted at the `reflex_engine` module.
--   [ ] **Implement the Reflex Engine logic:**
-    -   The `reflex_engine_task` will receive the `MSG_REFLEX_VECTOR` message.
-    -   It will perform a direct forward pass of the neural network using the vector data.
-    -   It will then send the resulting action vector as a command message to the `servo_controller` module.

-## Phase 4: Future Enhancements (Not Started)
+*   **[TODO] Sub-task: Establish Inter-ESP32 Communication**
+    *   **Description:** Implement a communication channel for the two ESP32s.
+    *   **Next Steps:**
+        *   Choose and implement a protocol (ESP-NOW is recommended).
+        *   Create a new `inter_esp_comm.c` module to handle message passing.
+        *   Define a clear message format for sharing status and coordinated goals.
+
+*   **[TODO] Sub-task: Implement Coordinated Motion**
+    *   **Description:** The ultimate goal of this phase. This involves deep integration between the two subsystems.
+    *   **Next Steps:**
+        *   **Offline:** Train a new, larger neural network on data from both the arm and base to create a **combined embedding space**.
+        *   **Online:** Implement a distributed planning system where a "master" ESP32 can send coordinated goal embeddings to the "slave" to perform complex tasks (e.g., moving while manipulating an object).
+        *   **Online:** Implement shared-state reflexes, such as the arm counter-balancing to prevent the base from tipping.
+
+## Phase 3: Future Enhancements (Not Started)
 
 *   **[TODO] Advanced Clustering:** Upgrade the training pipeline from K-Means to a Self-Organizing Map (SOM) for a more topologically meaningful gesture map.
 *   **[TODO] Real-time Obstacle Avoidance:** Integrate distance sensors (e.g., IR, Ultrasonic) into the planner's cost function to enable dynamic obstacle avoidance.
 *   **[TODO] Higher-Level Behavior Tree:** Implement a formal behavior tree on a host PC that can sequence complex, multi-step tasks by sending goal sequences to the robot.
 *   **[TODO] Vision System Integration:** Add a camera and a vision processing pipeline (e.g., on the host PC) to enable object detection and visual servoing.
+
 *   **[DONE] Sub-task: Implement Python-based Vision Processing**
     *   **Description:** Implement a Python script to configure the Synsense Speck camera for a specific task (e.g., edge detection) and read the output. This approach leverages the high-level `samna` and `sinabs` libraries, removing the need for a low-level C driver.
-    *   **Status:** An `edge_detector.py` script has been created, which defines an SNN model, aget_corrected_position_pynd configures the chip, and includes a loop for real-time inference.
-*   **[TODO] Coordinated Motion:** The ultimate goal of this phase. This involves deep integration between the two subsystems.
-    *   **Next Steps:**

-/**
- * @file generated_gestures.h.sample
- * @brief Sample of the gesture library and graph data structures.
- *
- * @note THIS IS A SAMPLE FILE. DO NOT EDIT.
- * The actual `generated_gestures.h` file is generated by a Python script
- * based on data collected from a specific robot. It should not be manually
- * created or modified.
- *
- * --- How to Generate This File ---
- *
- * This file is generated by the training pipeline script located at:
- *   `tools/training_pipeline.py`
- *
- * The pipeline script connects to the robot, collects trajectory data,
- * clusters the data to form "gestures", and then exports the final
- * gesture library and transition graph into `main/generated_gestures.h`.
- *
- * For detailed instructions on how to set up the environment and run the
- * training pipeline, please refer to the main agent instructions file:
- *   `AGENTS.md`
- *
- * --- Data Structure Format ---
- *
- * The file defines two main data structures:
- *
- * 1. `g_gesture_library`: An array of `GestureToken` structs. Each token
- *    represents a single learned motion primitive.
- *
- * 2. `g_gesture_graph`: A `GestureGraph` struct that contains the complete
- *    gesture library and the costs of transitioning between any two gestures.

-# Project Tests
+# Tests
 
-This directory contains the tests for the ESP32 Hebbian Learning Robot project. The testing framework is designed to be flexible, allowing for both offline unit testing with mock objects and online integration testing with real hardware.
+This directory contains unit tests for the project.
 
 ## Files
 
-*   `unit_test_script.py`: The main entry point for running all tests. It can be configured to run in different modes.
-*   `robot_client.py`: A crucial utility module that provides client classes for interacting with the robot's different interfaces (MCP server, console, and Feetech servos). It also contains mock server and serial port implementations for offline testing.
-*   `test_mcp_server.py`: Contains unit tests specifically for the MCP (Mission Control Protocol) server client (`MCPClient`).
-*   `test_torch.py`: A simple script to verify that the PyTorch and SNNTorch libraries are installed correctly, as they are dependencies for the training pipeline.
+*   `test_mcp_server.py`: A script to test the MCP server.
+*   `test_torch.py`: A script to test the PyTorch installation.
+*   `unit_test_script.py`: A script to run all the unit tests.
 
-## `robot_client.py` - The Core of Testing
-
-The `robot_client.py` module is central to the testing strategy. It provides a unified way to communicate with the robot's various components and allows tests to be run with or without hardware.
-
-### Client Classes
-
-*   `MCPClient`: A TCP client for sending commands to the robot's main MCP server (running on port 8888). It handles the JSON-based command protocol for high-level control.
-*   `ConsoleClient`: A client for interacting with the robot's serial console. It's used for sending CLI commands and reading log output.
-*   `FeetechClient`: A client that emulates a host controller for the Feetech serial bus servos. It's used for low-level servo testing.
+## Running the Tests
 
-### Mocking Infrastructure
+### Integration Tests (Python)
 
-To enable offline testing, `robot_client.py` also includes mock classes:
+To run the Python-based integration tests, which require a running ESP32 device, execute the `unit_test_script.py` script. You will need to provide the IP address of the device and the correct serial ports.
 
-*   `MockMCPServer`: A mock TCP server that emulates the robot's MCP server, allowing `MCPClient` to be tested without a real robot.
-*   `MockSerial`: A mock serial port that emulates the `pyserial` library, allowing `ConsoleClient` and `FeetechClient` to be tested offline. It can be configured to simulate various error conditions.
+```bash
+# Example
+python unit_test_script.py 192.168.1.100 /dev/ttyACM0 /dev/ttyACM1
+```
 
-## Running the Tests
+### Test Modes
 
-The `unit_test_script.py` script is the main runner for the test suite. It can be executed in two primary modes.
+The main test script `unit_test_script.py` can be run in two modes:
 
-### 1. Unit Test Mode (Offline)
+#### 1. Unit Test Mode (Default)
 
-This is the default mode. It runs the client code against the mock server and serial ports defined in `robot_client.py`. This mode does **not** require any hardware and is ideal for quickly verifying the logic of the Python client code and the robot's command parsing.
+This mode runs the Python client code against a mock ESP32 server and mock serial ports. It does **not** require any hardware and can be run on any machine with Python and `pyserial` installed. It is useful for quickly verifying the logic of the Python scripts.
 
-To run the unit tests:
 ```bash
 python unit_test_script.py --mode unit
 ```
 
-### 2. Integration Test Mode (Online)
+#### 2. Integration Test Mode
 
-This mode runs the tests against a real, running ESP32 device. You must provide the device's IP address and the correct serial port names for the console and Feetech interfaces. This is used to verify that the client code works correctly with the actual firmware.
+This mode runs the tests against a real, running ESP32 device. You must provide the device's IP address and the correct serial port names for the console and Feetech interfaces.
 
-To run the integration tests:
 ```bash
-# Example usage:
-python unit_test_script.py --mode integration --ip_address <ROBOT_IP> --console_port <CONSOLE_PORT> --feetech_port <FEETECH_PORT>
+# Example
+python unit_test_script.py --mode integration --ip_address 192.168.1.100 --console_port /dev/ttyACM0 --feetech_port /dev/ttyACM1
 ```
-
-Replace `<ROBOT_IP>`, `<CONSOLE_PORT>`, and `<FEETECH_PORT>` with the appropriate values for your hardware setup.
