+# Clean Code Guidelines
+
+## Constants Over Magic Numbers
+- Replace hard-coded values with named constants
+- Use descriptive constant names that explain the value's purpose
+- Keep constants at the top of the file or in a dedicated constants file
+
+## Meaningful Names
+- Variables, functions, and classes should reveal their purpose
+- Names should explain why something exists and how it's used
+- Avoid abbreviations unless they're universally understood
+
+## Smart Comments
+- Don't comment on what the code does - make the code self-documenting
+- Use comments to explain why something is done a certain way
+- Document APIs, complex algorithms, and non-obvious side effects
+
+## Single Responsibility
+- Each function should do exactly one thing
+- Functions should be small and focused
+- If a function needs a comment to explain what it does, it should be split
+
+## DRY (Don't Repeat Yourself)
+- Extract repeated code into reusable functions
+- Share common logic through proper abstraction
+- Maintain single sources of truth
+
+## Clean Structure
+- Keep related code together
+- Organize code in a logical hierarchy
+- Use consistent file and folder naming conventions
+
+## Encapsulation
+- Hide implementation details
+- Expose clear interfaces
+- Move nested conditionals into well-named functions
+
+## Code Quality Maintenance
+- Refactor continuously
+- Fix technical debt early
+- Leave code cleaner than you found it
+
+## Testing
+- Write tests before fixing bugs
+- Keep tests readable and maintainable
+- Test edge cases and error conditions
+
+## Version Control
+- Write clear commit messages
+- Make small, focused commits
+- Use meaningful branch names

+
+# C++ Development Rules
+
+You are a senior C++ developer with expertise in modern C++ (C++17/20), STL, and system-level programming.
+
+## Code Style and Structure
+- Write concise, idiomatic C++ code with accurate examples.
+- Follow modern C++ conventions and best practices.
+- Use object-oriented, procedural, or functional programming patterns as appropriate.
+- Leverage STL and standard algorithms for collection operations.
+- Use descriptive variable and method names (e.g., 'isUserSignedIn', 'calculateTotal').
+- Structure files into headers (*.hpp) and implementation files (*.cpp) with logical separation of concerns.
+
+## Naming Conventions
+- Use PascalCase for class names.
+- Use camelCase for variable names and methods.
+- Use SCREAMING_SNAKE_CASE for constants and macros.
+- Prefix member variables with an underscore or m_ (e.g., `_userId`, `m_userId`).
+- Use namespaces to organize code logically.
+## C++ Features Usage
+
+- Prefer modern C++ features (e.g., auto, range-based loops, smart pointers).
+- Use `std::unique_ptr` and `std::shared_ptr` for memory management.
+- Prefer `std::optional`, `std::variant`, and `std::any` for type-safe alternatives.
+- Use `constexpr` and `const` to optimize compile-time computations.
+- Use `std::string_view` for read-only string operations to avoid unnecessary copies.
+
+## Syntax and Formatting
+- Follow a consistent coding style, such as Google C++ Style Guide or your team’s standards.
+- Place braces on the same line for control structures and methods.
+- Use clear and consistent commenting practices.
+
+## Error Handling and Validation
+- Use exceptions for error handling (e.g., `std::runtime_error`, `std::invalid_argument`).
+- Use RAII for resource management to avoid memory leaks.
+- Validate inputs at function boundaries.
+- Log errors using a logging library (e.g., spdlog, Boost.Log).
+
+## Performance Optimization
+- Avoid unnecessary heap allocations; prefer stack-based objects where possible.
+- Use `std::move` to enable move semantics and avoid copies.
+- Optimize loops with algorithms from `<algorithm>` (e.g., `std::sort`, `std::for_each`).
+- Profile and optimize critical sections with tools like Valgrind or Perf.
+
+## Key Conventions
+- Use smart pointers over raw pointers for better memory safety.
+- Avoid global variables; use singletons sparingly.
+- Use `enum class` for strongly typed enumerations.
+- Separate interface from implementation in classes.
+- Use templates and metaprogramming judiciously for generic solutions.
+
+## Security
+- Use secure coding practices to avoid vulnerabilities (e.g., buffer overflows, dangling pointers).
+- Prefer `std::array` or `std::vector` over raw arrays.
+- Avoid C-style casts; use `static_cast`, `dynamic_cast`, or `reinterpret_cast` when necessary.
+- Enforce const-correctness in functions and member variables.
+
+## Documentation
+- Write clear comments for classes, methods, and critical logic.
+- Use Doxygen for generating API documentation.
+- Document assumptions, constraints, and expected behavior of code.
+
+Follow the official ISO C++ standards and guidelines for best practices in modern C++ development.

+## Architecture
+
+SPORE uses a modular architecture with automatic node discovery, health monitoring, and distributed task management.
+
+**Core Components:**
+- **Spore Framework**: Main framework class that orchestrates all components
+- **Network Manager**: WiFi connection handling and hostname configuration
+- **Cluster Manager**: Node discovery, member list management, and health monitoring
+- **API Server**: HTTP API server with dynamic endpoint registration
+- **Task Scheduler**: Cooperative multitasking system for background operations
+- **Node Context**: Central context providing event system and shared resources
+
+**Key Features:**
+- **Auto Discovery**: UDP-based node detection on port 4210
+- **Health Monitoring**: Continuous status checking via HTTP API
+- **Task Scheduling**: Background tasks at configurable intervals
+- **Event System**: Local and cluster-wide event publishing/subscription
+- **Status Tracking**: Automatic node categorization (ACTIVE, INACTIVE, DEAD)
+- **Resource Monitoring**: Memory, CPU, flash, and API endpoint tracking
+- **WiFi Fallback**: Automatic access point creation if connection fails
+
+📖 **Detailed Architecture:** See [`docs/Architecture.md`](./docs/Architecture.md) for comprehensive system design and implementation details.
+
+## Quick Start
+
+The Spore framework provides a simple, unified interface for all core functionality:
+
+```cpp
+#include <Arduino.h>
+#include "Spore.h"
+
+// Create Spore instance with custom labels
+Spore spore({
+    {"app", "my_app"},
+    {"role", "controller"}
+});
+
+void setup() {
+    spore.setup();
+    spore.begin();
+}
+
+void loop() {
+    spore.loop();
+}
+```
+
+**Adding Custom Services:**
+```cpp
+void setup() {
+    spore.setup();
+    
+    // Create and register custom services
+    RelayService* relayService = new RelayService(spore.getContext(), spore.getTaskManager(), 2);
+    spore.registerService(relayService);
+    
+    // Or using smart pointers
+    auto sensorService = std::make_shared<SensorService>(spore.getContext(), spore.getTaskManager());
+    spore.registerService(sensorService);
+    
+    // Start the API server and complete initialization
+    spore.begin();
+}
+```
+
+**Examples:** See [`examples/base/`](./examples/base/) for basic usage and [`examples/relay/`](./examples/relay/) for custom service integration.
+
+## Cluster Broadcast
+
+Broadcast an event to all peers using the centralized core broadcaster. Services never touch UDP directly; instead they fire a local event that the core transmits as a `CLUSTER_EVENT`.
+
+Usage:
+
+```cpp
+// 1) Apply locally via the same event your service already handles
+JsonDocument payload;
+payload["pattern"] = "rainbow_cycle";
+payload["brightness"] = 100;
+String payloadStr; serializeJson(payload, payloadStr);
+ctx.fire("api/neopattern", &payloadStr);
+
+// 2) Broadcast to peers via the core
+JsonDocument envelope;
+envelope["event"] = "api/neopattern";
+envelope["data"] = payloadStr; // JSON string
+String eventJson; serializeJson(envelope, eventJson);
+ctx.fire("cluster/broadcast", &eventJson);
+```
+
+Notes:
+- The core sends subnet-directed broadcasts (e.g., 192.168.1.255) for reliability.
+- Peers receive `CLUSTER_EVENT` and forward to local subscribers with `ctx.fire(event, data)`.
+- `data` can be a JSON string or nested JSON; receivers handle both.
+
+📖 See the dedicated guide: [`docs/ClusterBroadcast.md`](./docs/ClusterBroadcast.md)
+
+## Streaming API
+
+Real-time event bridge available at `/ws` using WebSocket.
+
+- Send JSON `{ event, payload }` to dispatch events via `ctx.fire`.
+- Receive all local events as `{ event, payload }`.
+
+Examples:
+```json
+{ "event": "api/neopattern/color", "payload": { "color": "#FF0000", "brightness": 128 } }
+```
+```json
+{ "event": "cluster/broadcast", "payload": { "event": "api/neopattern/color", "data": { "color": "#00FF00" } } }
+```
+
+📖 See the dedicated guide: [`docs/StreamingAPI.md`](./docs/StreamingAPI.md)
+
+## API Reference

+# SPORE Architecture & Implementation
+
+## System Overview
+
+SPORE (SProcket ORchestration Engine) is a cluster engine for ESP8266 microcontrollers that provides automatic node discovery, health monitoring, and over-the-air updates in a distributed network environment.
+
+## Core Components
+
+The system architecture consists of several key components working together:
+
+### Network Manager
+- **WiFi Connection Handling**: Automatic WiFi STA/AP configuration
+- **Hostname Configuration**: MAC-based hostname generation
+- **Fallback Management**: Automatic access point creation if WiFi connection fails
+
+### Cluster Manager
+- **Node Discovery**: UDP-based automatic node detection
+- **Member List Management**: Dynamic cluster membership tracking
+- **Health Monitoring**: Continuous node status checking
+- **Resource Tracking**: Monitor node resources and capabilities
+
+### API Server
+- **HTTP API Server**: RESTful API for cluster management
+- **Dynamic Endpoint Registration**: Services register endpoints via `registerEndpoints(ApiServer&)`
+- **Service Registry**: Track available services across the cluster
+- **Service Lifecycle**: Services register both endpoints and tasks through unified interface
+
+### Task Scheduler
+- **Cooperative Multitasking**: Background task management system (`TaskManager`)
+- **Service Task Registration**: Services register tasks via `registerTasks(TaskManager&)`
+- **Task Lifecycle Management**: Enable/disable tasks and set intervals at runtime
+- **Execution Model**: Tasks run in `Spore::loop()` when their interval elapses
+
+### Node Context
+- **Central Context**: Shared resources and configuration
+- **Event System**: Local and cluster-wide event publishing/subscription
+- **Resource Management**: Centralized resource allocation and monitoring
+
+## Auto Discovery Protocol
+
+The cluster uses a UDP-based discovery protocol for automatic node detection:
+
+### Discovery Process
+
+1. **Discovery Broadcast**: Nodes periodically send heartbeat messages on port `udp_port` (default 4210)
+2. **Response Handling**: Nodes respond with node update information containing their current state
+3. **Member Management**: Discovered nodes are added/updated in the cluster with current information
+4. **Node Synchronization**: Periodic broadcasts ensure all nodes maintain current cluster state
+
+### Protocol Details
+
+- **UDP Port**: 4210 (configurable via `Config.udp_port`)
+- **Heartbeat Message**: `CLUSTER_HEARTBEAT:hostname`
+- **Node Update Message**: `NODE_UPDATE:hostname:{json}`
+- **Broadcast Address**: 255.255.255.255
+- **Listen Interval**: `Config.cluster_listen_interval_ms` (default 10 ms)
+- **Heartbeat Interval**: `Config.heartbeat_interval_ms` (default 5000 ms)
+
+### Message Formats
+
+- **Heartbeat**: `CLUSTER_HEARTBEAT:hostname`
+  - Sender: each node, broadcast to 255.255.255.255:`udp_port` on interval
+  - Purpose: announce presence, prompt peers for node info, and keep liveness
+- **Node Update**: `NODE_UPDATE:hostname:{json}`
+  - Sender: node responding to heartbeat or broadcasting current state
+  - JSON fields: hostname, ip, uptime, optional labels
+  - Purpose: provide current node information for cluster synchronization
+
+### Discovery Flow
+
+1. **A node broadcasts** `CLUSTER_HEARTBEAT:hostname` to announce its presence
+2. **Each receiver responds** with `NODE_UPDATE:hostname:{json}` containing current node state
+3. **The sender**:
+   - Ensures the responding node exists or creates it with current IP and information
+   - Parses JSON and updates node info, `status = ACTIVE`, `lastSeen = now`
+   - Calculates `latency = now - lastHeartbeatSentAt` for network performance monitoring
+
+### Node Synchronization
+
+1. **Event-driven broadcasts**: Nodes broadcast `NODE_UPDATE:hostname:{json}` when node information changes
+2. **All receivers**: Update their memberlist entry for the broadcasting node
+3. **Purpose**: Ensures all nodes maintain current cluster state and configuration
+
+### Sequence Diagram

+
+    Note over N2: Update memberlist with latest information
+    N2-->>N2: Update Node A info, maintain ACTIVE status
+```
+
+### Listener Behavior
+
+The `cluster_listen` task parses one UDP packet per run and dispatches by prefix to:
+- **Heartbeat** → add/update responding node and send `NODE_UPDATE` response
+- **Node Update** → update node information and trigger memberlist logging
+
+### Timing and Intervals
+
+- **UDP Port**: `Config.udp_port` (default 4210)
+- **Listen Interval**: `Config.cluster_listen_interval_ms` (default 10 ms)
+- **Heartbeat Interval**: `Config.heartbeat_interval_ms` (default 5000 ms)
+
+### Node Status Categories
+
+Nodes are automatically categorized by their activity:
+
+- **ACTIVE**: lastSeen < `node_inactive_threshold_ms` (default 10s)
+- **INACTIVE**: < `node_dead_threshold_ms` (default 120s)
+- **DEAD**: ≥ `node_dead_threshold_ms`
+
+## Task Scheduling System
+
+The system runs several background tasks at different intervals:
+
+### Core System Tasks
+
+| Task | Interval (default) | Purpose |
+|------|--------------------|---------|
+| `cluster_listen` | 10 ms | Listen for heartbeat/node-info messages |
+| `status_update` | 1000 ms | Update node status categories, purge dead |
+| `heartbeat` | 5000 ms | Broadcast heartbeat and update local resources |
+
+### Task Management Features
+
+- **Dynamic Intervals**: Change execution frequency on-the-fly
+- **Runtime Control**: Enable/disable tasks without restart
+- **Status Monitoring**: Real-time task health tracking
+- **Resource Integration**: View task status with system resources
+
+## Event System
+
+The `NodeContext` provides an event-driven architecture for system-wide communication:
+
+### Event Subscription
+
+```cpp
+// Subscribe to events
+ctx.on("node/discovered", [](void* data) {
+    NodeInfo* node = static_cast<NodeInfo*>(data);
+    // Handle new node discovery
+});
+
+ctx.on("cluster/updated", [](void* data) {
+    // Handle cluster membership changes
+});
+```
+
+### Event Publishing
+
+```cpp
+// Publish events
+ctx.fire("node/discovered", &newNode);
+ctx.fire("cluster/updated", &clusterData);
+```
+
+### Available Events
+
+- **`node/discovered`**: New node added or local node refreshed
+
+## Resource Monitoring
+
+Each node tracks comprehensive system resources:
+
+### System Resources
+
+- **Free Heap Memory**: Available RAM in bytes
+- **Chip ID**: Unique ESP8266 identifier
+- **SDK Version**: ESP8266 firmware version
+- **CPU Frequency**: Operating frequency in MHz
+- **Flash Chip Size**: Total flash storage in bytes
+
+### API Endpoint Registry
+
+- **Dynamic Discovery**: Automatically detect available endpoints
+- **Method Information**: HTTP method (GET, POST, etc.)
+- **Service Catalog**: Complete service registry across cluster
+
+### Health Metrics
+
+- **Response Time**: API response latency
+- **Uptime**: System uptime in milliseconds
+- **Connection Status**: Network connectivity health
+- **Resource Utilization**: Memory and CPU usage
+
+## WiFi Fallback System
+
+The system includes automatic WiFi fallback for robust operation:
+
+### Fallback Process
+
+1. **Primary Connection**: Attempts to connect to configured WiFi network
+2. **Connection Failure**: If connection fails, creates an access point
+3. **Hostname Generation**: Automatically generates hostname from MAC address
+4. **Service Continuity**: Maintains cluster functionality in fallback mode
+
+### Configuration
+
+- **Hostname**: Derived from MAC (`esp-<mac>`) and assigned to `ctx.hostname`
+- **AP Mode**: If STA connection fails, device switches to AP mode with configured SSID/password
+
+## Cluster Topology
+
+### Node Types
+
+- **Master Node**: Primary cluster coordinator (if applicable)
+- **Worker Nodes**: Standard cluster members
+- **Edge Nodes**: Network edge devices
+
+### Network Architecture
+
+- UDP broadcast-based discovery and heartbeats on local subnet
+- Optional HTTP polling (disabled by default; node info exchanged via UDP)
+
+## Data Flow
+
+### Node Discovery
+1. **UDP Broadcast**: Nodes broadcast discovery packets on port 4210
+2. **UDP Response**: Receiving nodes respond with hostname
+3. **Registration**: Discovered nodes are added to local cluster member list
+
+### Health Monitoring
+1. **Periodic Checks**: Cluster manager updates node status categories
+2. **Status Collection**: Each node updates resources via UDP node-info messages
+
+### Task Management
+1. **Scheduling**: `TaskManager` executes registered tasks at configured intervals
+2. **Execution**: Tasks run cooperatively in the main loop without preemption
+3. **Monitoring**: Task status is exposed via REST (`/api/tasks/status`)
+
+## Performance Characteristics
+
+### Memory Usage
+
+- **Base System**: ~15-20KB RAM (device dependent)
+- **Per Task**: ~100-200 bytes per task
+- **Cluster Members**: ~50-100 bytes per member
+- **API Endpoints**: ~20-30 bytes per endpoint
+
+### Network Overhead
+
+- **Discovery Packets**: 64 bytes every 1 second
+- **Health Checks**: ~200-500 bytes every 1 second
+- **Status Updates**: ~1-2KB per node
+- **API Responses**: Varies by endpoint (typically 100B-5KB)
+
+### Processing Overhead
+
+- **Task Execution**: Minimal overhead per task
+- **Event Processing**: Fast event dispatch
+- **JSON Parsing**: Efficient ArduinoJson usage
+- **Network I/O**: Asynchronous operations
+
+## Security Considerations
+
+### Current Implementation
+
+- **Network Access**: Local network only (no internet exposure)
+- **Authentication**: None currently implemented; LAN-only access assumed
+- **Data Validation**: Basic input validation
+- **Resource Limits**: Memory and processing constraints
+
+### Future Enhancements
+
+- **TLS/SSL**: Encrypted communications
+- **API Keys**: Authentication for API access
+- **Access Control**: Role-based permissions
+- **Audit Logging**: Security event tracking
+
+## Scalability
+
+### Cluster Size Limits
+
+- **Theoretical**: Up to 255 nodes (IP subnet limit)
+- **Practical**: 20-50 nodes for optimal performance
+- **Memory Constraint**: ~8KB available for member tracking
+- **Network Constraint**: UDP packet size limits
+
+### Performance Scaling
+
+- **Linear Scaling**: Most operations scale linearly with node count
+- **Discovery Overhead**: Increases with cluster size
+- **Health Monitoring**: Parallel HTTP requests
+- **Task Management**: Independent per-node execution
+
+## Configuration Management
+
+SPORE implements a persistent configuration system that manages device settings across reboots and provides runtime reconfiguration capabilities.
+
+### Configuration Architecture
+
+The configuration system consists of several key components:
+
+- **`Config` Class**: Central configuration management with default constants
+- **LittleFS Storage**: Persistent file-based storage (`/config.json`)
+- **Runtime Updates**: Live configuration changes via HTTP API
+- **Automatic Persistence**: Configuration changes are automatically saved
+
+### Configuration Categories
+
+| Category | Description | Examples |
+|----------|-------------|----------|
+| **WiFi Configuration** | Network connection settings | SSID, password, timeouts |
+| **Network Configuration** | Network service settings | UDP port, API server port |
+| **Cluster Configuration** | Cluster management settings | Discovery intervals, heartbeat timing |
+| **Node Status Thresholds** | Health monitoring thresholds | Active/inactive/dead timeouts |
+| **System Configuration** | Core system settings | Restart delay, JSON document size |
+| **Memory Management** | Resource management settings | Memory thresholds, HTTP request limits |
+
+### Configuration Lifecycle
+
+1. **Boot Process**: Load configuration from `/config.json` or use defaults
+2. **Runtime Updates**: Configuration changes via HTTP API
+3. **Persistent Storage**: Changes automatically saved to LittleFS
+4. **Service Integration**: Configuration applied to all system services
+
+### Default Value Management
+
+All default values are defined as `constexpr` constants in the `Config` class:
+
+```cpp
+static constexpr const char* DEFAULT_WIFI_SSID = "shroud";
+static constexpr uint16_t DEFAULT_UDP_PORT = 4210;
+static constexpr unsigned long DEFAULT_HEARTBEAT_INTERVAL_MS = 5000;
+```
+
+This ensures:
+- **Single Source of Truth**: All defaults defined once
+- **Type Safety**: Compile-time type checking
+- **Maintainability**: Easy to update default values
+- **Consistency**: Same defaults used in `setDefaults()` and `loadFromFile()`
+
+### Environment Variables
+
+```bash
+# API node IP for cluster management
+export API_NODE=192.168.1.100
+```
+
+### PlatformIO Configuration
+
+The project uses PlatformIO with the following configuration:
+
+- **Framework**: Arduino
+- **Board**: ESP-01 with 1MB flash
+- **Upload Speed**: 115200 baud
+- **Flash Mode**: DOUT (required for ESP-01S)
+
+### Dependencies
+
+The project requires the following libraries:
+- `esp32async/ESPAsyncWebServer@^3.8.0` - HTTP API server
+- `bblanchon/ArduinoJson@^7.4.2` - JSON processing
+- `arkhipenko/TaskScheduler@^3.8.5` - Cooperative multitasking
+
+## Development Workflow

+## Cluster Broadcast (CLUSTER_EVENT)
+
+### Overview
+
+Spore supports cluster-wide event broadcasting via UDP. Services publish a local event, and the core broadcasts it to peers as a `CLUSTER_EVENT`. Peers receive the event and forward it to local subscribers through the internal event bus.
+
+- **Local trigger**: `ctx.fire("cluster/broadcast", eventJson)`
+- **UDP message**: `CLUSTER_EVENT:{json}`
+- **Receiver action**: Parses `{json}` and calls `ctx.fire(event, data)`
+
+This centralizes network broadcast in core, so services never touch UDP directly.
+
+### Message format
+
+- UDP payload prefix: `CLUSTER_EVENT:`
+- JSON body:
+```json
+{
+  "event": "<event-name>",
+  "data": "<json-string>" // or an inline JSON object/array
+}
+```
+
+Notes:
+- The receiver accepts `data` as either a JSON string or a nested JSON object/array. Nested JSON is serialized back to a string before firing the local event.
+- Keep payloads small (UDP, default buffer 512 bytes).
+
+### Core responsibilities
+
+- `ClusterManager` registers a centralized handler:
+  - Subscribes to `cluster/broadcast` to send the provided event JSON over UDP broadcast.
+  - Listens for incoming UDP `CLUSTER_EVENT` messages and forwards them to local subscribers via `ctx.fire(event, data)`.
+- Broadcast target uses subnet-directed broadcast (e.g., `192.168.1.255`) for better reliability. Both nodes must share the same `udp_port`.
+
+### Service responsibilities
+
+Services send and receive events using the local event bus.
+
+1) Subscribe to an event name and apply state from `data`:
+```cpp
+ctx.on("api/neopattern", [this](void* dataPtr) {
+    String* jsonStr = static_cast<String*>(dataPtr);
+    if (!jsonStr) return;
+    JsonDocument doc;
+    if (deserializeJson(doc, *jsonStr)) return;
+    JsonObject obj = doc.as<JsonObject>();
+    // Parse and apply fields from obj
+});
+```
+
+2) Build a control payload and update locally via the same event:
+```cpp
+JsonDocument payload;
+payload["pattern"] = "rainbow_cycle"; // example
+payload["brightness"] = 100;
+String payloadStr; serializeJson(payload, payloadStr);
+ctx.fire("api/neopattern", &payloadStr);
+``;
+
+3) Broadcast to peers by delegating to core:
+```cpp
+JsonDocument envelope;
+envelope["event"] = "api/neopattern";
+envelope["data"] = payloadStr; // JSON string
+String eventJson; serializeJson(envelope, eventJson);
+ctx.fire("cluster/broadcast", &eventJson);
+```
+
+With this flow, services have a single codepath for applying state (the event handler). Broadcasting simply reuses the same payload.
+
+### Logging
+
+- Core logs source IP, payload length, and event name for received `CLUSTER_EVENT`s.
+- Services can log when submitting `cluster/broadcast` and when applying control events.
+
+### Networking considerations
+
+- Ensure all nodes:
+  - Listen on the same `udp_port`.
+  - Are in the same subnet (for subnet-directed broadcast).
+- Some networks may block global broadcast (`255.255.255.255`). Subnet-directed broadcast is used by default.
+
+### Troubleshooting
+
+- If peers do not react:
+  - Confirm logs show `CLUSTER_EVENT raw from <ip>` on the receiver.
+  - Verify UDP port alignment and WiFi connection/subnet.
+  - Check payload size (<512 bytes by default) and JSON validity.
+  - Ensure the service subscribed to the correct `event` name and handles `data`.

+# SPORE Configuration Management
+
+## Overview
+
+SPORE implements a persistent configuration system that manages device settings across reboots and provides runtime reconfiguration capabilities. The system uses LittleFS for persistent storage and provides both programmatic and HTTP API access to configuration parameters.
+
+## Configuration Architecture
+
+### Core Components
+
+- **`Config` Class**: Central configuration management
+- **LittleFS Storage**: Persistent file-based storage (`/config.json`)
+- **Default Constants**: Single source of truth for all default values
+- **Runtime Updates**: Live configuration changes via HTTP API
+- **Automatic Persistence**: Configuration changes are automatically saved
+
+### Configuration Categories
+
+The configuration system manages several categories of settings:
+
+| Category | Description | Examples |
+|----------|-------------|----------|
+| **WiFi Configuration** | Network connection settings | SSID, password, timeouts |
+| **Network Configuration** | Network service settings | UDP port, API server port |

+
+## Configuration Lifecycle
+
+### 1. Boot Process
+
+```mermaid
+graph TD
+    A[System Boot] --> B[Initialize LittleFS]
+    B --> C{Config File Exists?}
+    C -->|Yes| D[Load from File]
+    C -->|No| E[Use Defaults]
+    D --> F[Apply Configuration]
+    E --> G[Save Defaults to File]
+    G --> F
+    F --> H[Start Services]
+```
+
+**Boot Sequence:**
+
+1. **LittleFS Initialization**: Mount the filesystem for persistent storage
+2. **Configuration Loading**: Attempt to load `/config.json`
+3. **Fallback to Defaults**: If no config file exists, use hardcoded defaults
+4. **Default Persistence**: Save default configuration to file for future boots
+5. **Service Initialization**: Apply configuration to all system services
+
+### 2. Runtime Configuration
+
+```mermaid
+graph TD
+    A[HTTP API Request] --> B[Validate Parameters]
+    B --> C[Update Config Object]
+    C --> D[Save to File]

+    E -->|Yes| F[Schedule Restart]
+    E -->|No| G[Apply Changes]
+    F --> H[Send Response]
+    G --> H
+```
+
+**Runtime Update Process:**
+
+1. **API Request**: Configuration change via HTTP API
+2. **Parameter Validation**: Validate input parameters
+3. **Memory Update**: Update configuration object in memory
+4. **Persistent Save**: Save changes to `/config.json`
+5. **Service Notification**: Notify affected services of changes
+6. **Restart if Needed**: Restart system for certain configuration changes
+
+## Configuration File Format
+
+### JSON Structure
+
+The configuration is stored as a JSON file with the following structure:
+
+```json
+{
+  "wifi": {
+    "ssid": "MyNetwork",
+    "password": "mypassword",
+    "connect_timeout_ms": 15000,
+    "retry_delay_ms": 500
+  },
+  "network": {
+    "udp_port": 4210,
+    "api_server_port": 80
+  },
+  "cluster": {
+    "heartbeat_interval_ms": 5000,
+    "cluster_listen_interval_ms": 10,
+    "status_update_interval_ms": 1000
+  },
+  "thresholds": {
+    "node_active_threshold_ms": 10000,
+    "node_inactive_threshold_ms": 60000,
+    "node_dead_threshold_ms": 120000
+  },
+  "system": {
+    "restart_delay_ms": 10,
+    "json_doc_size": 1024
+  },
+  "memory": {
+    "low_memory_threshold_bytes": 10000,
+    "critical_memory_threshold_bytes": 5000,
+    "max_concurrent_http_requests": 3
+  },
+  "_meta": {
+    "version": "1.0",
+    "saved_at": 1234567890
+  }
+}
+```
+
+### Metadata Fields
+
+- **`version`**: Configuration schema version for future compatibility
+- **`saved_at`**: Timestamp when configuration was saved (millis())
+
+## Default Configuration Constants
+
+All default values are defined as `constexpr` constants in the `Config` class header:
+
+```cpp
+// Default Configuration Constants
+static constexpr const char* DEFAULT_WIFI_SSID = "shroud";
+static constexpr const char* DEFAULT_WIFI_PASSWORD = "th3r31sn0sp00n";
+static constexpr uint16_t DEFAULT_UDP_PORT = 4210;
+static constexpr uint16_t DEFAULT_API_SERVER_PORT = 80;
+// ... additional constants
+```
+
+### Benefits of Constants
+
+- **Single Source of Truth**: All defaults defined once
+- **Type Safety**: Compile-time type checking
+- **Maintainability**: Easy to update default values
+- **Consistency**: Same defaults used in `setDefaults()` and `loadFromFile()`
+
+## Configuration Methods
+
+### Core Methods
+
+| Method | Purpose | Parameters |
+|--------|---------|------------|
+| `setDefaults()` | Initialize with default values | None |
+| `loadFromFile()` | Load configuration from persistent storage | `filename` (optional) |
+| `saveToFile()` | Save configuration to persistent storage | `filename` (optional) |
+
+### Loading Process
+
+```cpp
+bool Config::loadFromFile(const String& filename) {
+    // 1. Initialize LittleFS
+    if (!LittleFS.begin()) {
+        LOG_ERROR("Config", "LittleFS not initialized");
+        return false;
+    }
+    
+    // 2. Check file existence
+    if (!LittleFS.exists(filename)) {
+        LOG_DEBUG("Config", "Config file does not exist");
+        return false;
+    }
+    
+    // 3. Parse JSON with fallback defaults
+    wifi_ssid = doc["wifi"]["ssid"] | DEFAULT_WIFI_SSID;
+    wifi_password = doc["wifi"]["password"] | DEFAULT_WIFI_PASSWORD;
+    // ... additional fields
+    
+    return true;
+}
+```
+
+### Saving Process
+
+```cpp
+bool Config::saveToFile(const String& filename) {
+    // 1. Create JSON document
+    JsonDocument doc;
+    
+    // 2. Serialize all configuration fields
+    doc["wifi"]["ssid"] = wifi_ssid;
+    doc["wifi"]["password"] = wifi_password;
+    // ... additional fields
+    
+    // 3. Add metadata
+    doc["_meta"]["version"] = "1.0";
+    doc["_meta"]["saved_at"] = millis();
+    
+    // 4. Write to file
+    size_t bytesWritten = serializeJson(doc, file);
+    return bytesWritten > 0;
+}
+```
+
+## Error Handling
+
+### Common Error Scenarios
+
+| Scenario | Error Handling | Recovery |
+|----------|----------------|----------|
+| **LittleFS Init Failure** | Log warning, use defaults | Continue with default configuration |
+| **File Not Found** | Log debug message, return false | Caller handles fallback to defaults |
+| **JSON Parse Error** | Log error, return false | Caller handles fallback to defaults |
+| **Write Failure** | Log error, return false | Configuration not persisted |
+| **Memory Allocation Failure** | Log error, return false | Operation aborted |
+
+### Logging Levels
+
+- **ERROR**: Critical failures that prevent operation
+- **WARN**: Non-critical issues that affect functionality
+- **INFO**: Normal operation events
+- **DEBUG**: Detailed diagnostic information
+
+## Configuration Validation
+
+### Input Validation
+
+- **Required Fields**: SSID and password are mandatory for WiFi configuration
+- **Range Validation**: Numeric values are validated against reasonable ranges
+- **Type Validation**: JSON parsing ensures correct data types
+- **Length Limits**: String fields have maximum length constraints
+
+### Default Value Fallback
+
+The system uses the `|` operator for safe fallback to defaults:
+
+```cpp
+// Safe loading with fallback
+wifi_ssid = doc["wifi"]["ssid"] | DEFAULT_WIFI_SSID;
+udp_port = doc["network"]["udp_port"] | DEFAULT_UDP_PORT;
+```
+
+This ensures that:
+- Missing fields use default values
+- Invalid values are replaced with defaults
+- System remains functional with partial configuration
+
+## Performance Considerations
+
+### Memory Usage
+
+- **Configuration Object**: ~200 bytes in RAM
+- **JSON Document**: ~1KB during parsing/saving
+- **LittleFS Overhead**: ~2-4KB for filesystem
+
+### Storage Requirements
+
+- **Config File**: ~500-800 bytes on disk
+- **LittleFS Minimum**: ~64KB partition size
+- **Available Space**: Depends on flash size (1MB+ recommended)
+
+### Processing Overhead
+
+- **Load Time**: ~10-50ms for JSON parsing
+- **Save Time**: ~20-100ms for JSON serialization
+- **File I/O**: Minimal impact on system performance
+
+## Security Considerations
+
+### Current Implementation
+
+- **Local Storage Only**: Configuration stored on device filesystem
+- **No Encryption**: Plain text storage (LAN-only access assumed)
+- **Access Control**: No authentication for configuration changes
+
+### Future Enhancements
+
+- **Configuration Encryption**: Encrypt sensitive fields (passwords)
+- **Access Control**: Authentication for configuration changes
+- **Audit Logging**: Track configuration modifications
+- **Backup/Restore**: Configuration backup and restore capabilities
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Configuration Not Persisting**
+   - Check LittleFS initialization
+   - Verify file write permissions
+   - Monitor available flash space
+
+2. **Default Values Not Applied**
+   - Verify constants are properly defined
+   - Check JSON parsing errors
+   - Ensure fallback logic is working
+
+3. **Configuration Corruption**
+   - Delete `/config.json` to reset to defaults
+   - Check for JSON syntax errors
+   - Verify file system integrity
+
+### Debug Commands
+
+```bash
+# Check configuration status
+curl -s http://192.168.1.100/api/network/status | jq '.'
+
+# View current WiFi settings
+curl -s http://192.168.1.100/api/network/status | jq '.wifi'
+
+# Test configuration save
+curl -X POST http://192.168.1.100/api/network/wifi/config \
+  -d "ssid=TestNetwork&password=testpass"
+```
+
+## Best Practices
+
+### Configuration Management
+
+1. **Use Constants**: Always define defaults as constants
+2. **Validate Input**: Check all configuration parameters
+3. **Handle Errors**: Implement proper error handling
+4. **Log Changes**: Log configuration modifications
+5. **Test Fallbacks**: Ensure default fallbacks work correctly
+
+### Development Guidelines
+
+1. **Single Source**: Define each default value only once
+2. **Type Safety**: Use appropriate data types
+3. **Documentation**: Document all configuration parameters
+4. **Versioning**: Include version metadata in config files
+5. **Backward Compatibility**: Handle old configuration formats

+## PlatformIO Configuration
+
+### Framework and Board
+
+The project uses PlatformIO with the following configuration (excerpt):
+
+```ini
+[platformio]
+default_envs = base
+src_dir = .
+data_dir = ${PROJECT_DIR}/examples/${PIOENV}/data
+
+[common]
+monitor_speed = 115200
+lib_deps = 
+    esp32async/ESPAsyncWebServer@^3.8.0
+    bblanchon/ArduinoJson@^7.4.2
+
+[env:base]
+platform = platformio/espressif8266@^4.2.1
+board = esp01_1m
+framework = arduino
+upload_speed = 115200
+monitor_speed = 115200
+board_build.f_cpu = 80000000L
+board_build.flash_mode = qio
+board_build.filesystem = littlefs
+; note: somehow partition table is not working, so we need to use the ldscript
+board_build.ldscript = eagle.flash.1m64.ld
+lib_deps = ${common.lib_deps}
+build_src_filter = 
+    +<examples/base/*.cpp>
+    +<src/spore/*.cpp>
+    +<src/spore/core/*.cpp>
+    +<src/spore/services/*.cpp>

+
+[env:d1_mini]
+platform = platformio/espressif8266@^4.2.1
+board = d1_mini

+    +<src/spore/types/*.cpp>
+    +<src/spore/util/*.cpp>
+    +<src/internal/*.cpp>
+```
+
+### Dependencies
+
+The project requires the following libraries (resolved via PlatformIO):
+
+```ini
+lib_deps =
+    esp32async/ESPAsyncWebServer@^3.8.0
+    bblanchon/ArduinoJson@^7.4.2
+```
+
+### Filesystem, Linker Scripts, and Flash Layout
+
+This project uses LittleFS as the filesystem on ESP8266. Flash layout is controlled by the linker script (ldscript) selected per environment in `platformio.ini`.
+
+- **Filesystem**: LittleFS (replaces SPIFFS). Although ldscripts reference SPIFFS in their names, the reserved region is used by LittleFS transparently.
+- **Why ldscript matters**: It defines maximum sketch size and the size of the filesystem area in flash.
+
+| Board / Env | Flash size | ldscript | Filesystem | FS size | Notes |
+|-------------|------------|---------|------------|---------|-------|
+| esp01_1m    | 1MB        | `eagle.flash.1m64.ld` | LittleFS | 64KB | Prioritizes sketch size on 1MB modules. OTA is constrained on 1MB.
+| d1_mini     | 4MB        | `eagle.flash.4m1m.ld` | LittleFS | 1MB  | Standard 4M/1M layout; ample space for firmware and data.
+
+Configured in `platformio.ini`:
+
+```ini
+[env:esp01_1m]
+board_build.filesystem = littlefs
+board_build.ldscript = eagle.flash.1m64.ld
+
+[env:d1_mini]
+board_build.filesystem = littlefs
+board_build.ldscript = eagle.flash.4m1m.ld
+```
+
+Notes:
+- The ldscript name indicates total flash and filesystem size (e.g., `4m1m` = 4MB flash with 1MB FS; `1m64` = 1MB flash with 64KB FS).
+- LittleFS works within the filesystem region defined by the ldscript, despite SPIFFS naming.
+- If you need a different FS size, select an appropriate ldscript variant and keep `board_build.filesystem = littlefs`.
+- On ESP8266, custom partition CSVs are not used for layout; the linker script defines the flash map. This project removed prior `board_build.partitions` usage in favor of explicit `board_build.ldscript` entries per environment.
+
+## Building
+
+### Basic Build Commands
+
+Build the firmware for specific chip:
+
+```bash
+# Build for ESP-01 1MB
+./ctl.sh build target esp01_1m

+
+# Build with verbose output
+pio run -v
+```
+
+### Build Targets
+
+Available build targets:
+
+| Target | Description | Flash Size |
+|--------|-------------|------------|
+| `esp01_1m` | ESP-01 with 1MB flash | 1MB |
+| `d1_mini` | D1 Mini with 4MB flash | 4MB |
+
+### Build Artifacts
+
+After successful build:
+
+- **Firmware**: `.pio/build/{target}/firmware.bin`

+# Monitoring Service
+
+Exposes system resource metrics via HTTP for observability.
+
+## Overview
+
+- **Service name**: `MonitoringService`
+- **Endpoint**: `GET /api/monitoring/resources`
+- **Metrics**: CPU usage, memory, filesystem, uptime
+
+## Endpoint
+
+### GET /api/monitoring/resources
+
+Returns real-time system resource metrics.
+
+Response fields:
+- `cpu.current_usage`: Current CPU usage percent
+- `cpu.average_usage`: Average CPU usage percent
+- `cpu.max_usage`: Max observed CPU usage
+- `cpu.min_usage`: Min observed CPU usage
+- `cpu.measurement_count`: Number of measurements
+- `cpu.is_measuring`: Whether measurement is active
+- `memory.free_heap`: Free heap bytes
+- `memory.total_heap`: Total heap bytes (approximate)
+- `memory.min_free_heap`: Minimum free heap (0 on ESP8266)
+- `memory.max_alloc_heap`: Max allocatable heap (0 on ESP8266)
+- `memory.heap_fragmentation`: Fragmentation percent (0 on ESP8266)
+- `filesystem.total_bytes`: LittleFS total bytes
+- `filesystem.used_bytes`: Used bytes
+- `filesystem.free_bytes`: Free bytes
+- `filesystem.usage_percent`: Usage percent
+- `system.uptime_ms`: Uptime in milliseconds
+- `system.uptime_seconds`: Uptime in seconds
+- `system.uptime_formatted`: Human-readable uptime
+
+Example:
+```json
+{
+  "cpu": {
+    "current_usage": 3.5,
+    "average_usage": 2.1,
+    "max_usage": 15.2,
+    "min_usage": 0.0,
+    "measurement_count": 120,
+    "is_measuring": true
+  },
+  "memory": {
+    "free_heap": 48748,
+    "total_heap": 81920,
+    "min_free_heap": 0,
+    "max_alloc_heap": 0,
+    "heap_fragmentation": 0,
+    "heap_usage_percent": 40.4
+  },
+  "filesystem": {
+    "total_bytes": 65536,
+    "used_bytes": 10240,
+    "free_bytes": 55296,
+    "usage_percent": 15.6
+  },
+  "system": {
+    "uptime_ms": 123456,
+    "uptime_seconds": 123,
+    "uptime_formatted": "0h 2m 3s"
+  }
+}
+```
+
+## Implementation Notes
+
+- `MonitoringService` reads from `CpuUsage` and ESP8266 SDK APIs.
+- Filesystem metrics are gathered from LittleFS.
+- CPU measurement is bracketed by `Spore::loop()` calling `cpuUsage.startMeasurement()` and `cpuUsage.endMeasurement()`.
+
+## Troubleshooting
+
+- If `filesystem.total_bytes` is zero, ensure LittleFS is enabled in `platformio.ini` and an FS image is uploaded.
+- CPU usage values remain zero until the main loop runs and CPU measurement is started.

+# StaticFileService
+
+Serves static files from the device's LittleFS filesystem over HTTP.
+
+## Overview
+
+- Service name: `StaticFileService`
+- Mounts: LittleFS at startup
+- Endpoints:
+  - GET / → serves /index.html
+  - GET /* → serves any file under LittleFS by path
+
+Files are looked up relative to the filesystem root. If a requested path is empty or `/`, it falls back to `index.html`. Unknown paths return 404; a helper exists to fall back to `index.html` for SPA routing if desired.
+
+## Content types
+
+Determined by filename extension:
+
+- .html, .htm → text/html
+- .css → text/css
+- .js → application/javascript
+- .json → application/json
+- .png → image/png
+- .jpg, .jpeg → image/jpeg
+- .gif → image/gif
+- .svg → image/svg+xml
+- .ico → image/x-icon
+- default → application/octet-stream
+
+## Building and uploading the filesystem
+
+Place your web assets under the `data/` folder at the project root. The build system packages `data/` into a LittleFS image matching the environment's flash layout.
+
+### Upload via PlatformIO
+
+```bash
+# Build and upload filesystem for esp01_1m
+pio run -e esp01_1m -t uploadfs
+
+# Build and upload filesystem for d1_mini
+pio run -e d1_mini -t uploadfs
+```
+
+### Manual image build (optional)
+
+There are helper commands in `ctl.sh` if you need to build and flash the FS image manually:
+
+```bash
+# Build image from ./data into littlefs.bin
+./ctl.sh mkfs
+
+# Flash image at preconfigured offset
+./ctl.sh flashfs
+```
+
+Note: Offsets and sizes must match the environment's ldscript. The project defaults are:
+
+- esp01_1m: ldscript `eagle.flash.1m64.ld` (64KB FS)
+- d1_mini: ldscript `eagle.flash.4m1m.ld` (1MB FS)
+
+See `docs/Development.md` for details on filesystem and ldscript mapping.
+
+## Enabling the service
+
+`StaticFileService` is registered as a core service in the framework and enabled by default:
+
+```cpp
+// part of Spore::registerCoreServices()
+auto staticFileService = std::make_shared<StaticFileService>(ctx, apiServer);
+services.push_back(staticFileService);
+```
+
+If you maintain a custom build without the default services, ensure you instantiate and add the service before starting the API server.
+
+## Routing notes
+
+- Place your SPA assets in `data/` and reference paths relatively.
+- To support client-side routing, you can adapt `handleNotFound` to always serve `/index.html` for unknown paths.
+
+## Troubleshooting
+
+- "LittleFS Mount Failed": Ensure `board_build.filesystem = littlefs` is set and the ldscript provides a filesystem region.
+- 404 for known files: Confirm the file exists under `data/` and was uploaded (`pio run -t uploadfs`).
+- Incorrect MIME type: Add the extension mapping to `getContentType()` if using custom extensions.

+## Streaming API (WebSocket)
+
+### Overview
+
+The streaming API exposes an event-driven WebSocket at `/ws`. It bridges between external clients and the internal event bus:
+
+- Incoming WebSocket JSON `{ event, payload }` → `ctx.fire(event, payload)`
+- Local events → broadcasted to all connected WebSocket clients as `{ event, payload }`
+
+This allows real-time control and observation of the system without polling.
+
+### URL
+
+- `ws://<device-ip>/ws`
+
+### Message Format
+
+- Client → Device
+```json
+{
+  "event": "<event-name>",
+  "payload": "<json-string>" | { /* inline JSON */ }
+}
+```
+
+- Device → Client
+```json
+{
+  "event": "<event-name>",
+  "payload": "<json-string>"
+}
+```
+
+Notes:
+- The device accepts `payload` as a string or a JSON object/array. Objects are serialized into a string before dispatching to local subscribers to keep a consistent downstream contract.
+- A minimal ack `{ "ok": true }` is sent after a valid inbound message.
+
+#### Echo suppression (origin tagging)
+
+- To prevent the sender from receiving an immediate echo of its own message, the server injects a private field into JSON payloads:
+  - `_origin: "ws:<clientId>"`
+- When re-broadcasting local events to WebSocket clients, the server:
+  - Strips the `_origin` field from the outgoing payload
+  - Skips the originating `clientId` so only other clients receive the message
+  - If a payload is not valid JSON (plain string), no origin tag is injected and the message may be echoed
+
+### Event Bus Integration
+
+- The WebSocket registers an `onAny` subscriber to `NodeContext` so that all local events are mirrored to clients.
+- Services should subscribe to specific events via `ctx.on("<name>", ...)`.
+
+### Examples
+
+1) Set a solid color on NeoPattern:
+```json
+{
+  "event": "api/neopattern/color",
+  "payload": { "color": "#FF0000", "brightness": 128 }
+}
+```
+
+2) Broadcast a cluster event (delegated to core):
+```json
+{
+  "event": "cluster/broadcast",
+  "payload": {
+    "event": "api/neopattern/color",
+    "data": { "color": "#00FF00", "brightness": 128 }
+  }
+}
+```
+
+### Reference Implementation
+
+- WebSocket setup and bridging are implemented in `ApiServer`.
+- Global event subscription uses `NodeContext::onAny`.
+
+Related docs:
+- [`ClusterBroadcast.md`](./ClusterBroadcast.md) — centralized UDP broadcasting and CLUSTER_EVENT format
+
+### Things to consider
+
+- High-frequency updates can overwhelm ESP8266:
+  - Frequent JSON parse/serialize and `String` allocations fragment heap and may cause resets (e.g., Exception(3)).
+  - UDP broadcast on every message amplifies load; WiFi/UDP buffers can back up.
+  - Prefer ≥50–100 ms intervals; microbursts at 10 ms are risky.
+- Throttle and coalesce:
+  - Add a minimum interval in the core `cluster/broadcast` handler.
+  - Optionally drop redundant updates (e.g., same color as previous).
+- Reduce allocations:
+  - Reuse `StaticJsonDocument`/preallocated buffers in hot paths.
+  - Avoid re-serializing when possible; pass-through payload strings.
+  - Reserve `String` capacity when reuse is needed.
+- Yielding:
+  - Call `yield()` in long-running or bursty paths to avoid WDT.
+- Packet size:
+  - Keep payloads small to fit `ClusterProtocol::UDP_BUF_SIZE` and reduce airtime.

+# Task Management System
+
+The SPORE system includes a comprehensive TaskManager that provides a clean interface for managing system tasks. This makes it easy to add, configure, and control background tasks without cluttering the main application code.
+
+## Overview
+
+The TaskManager system provides:
+- **Easy Task Registration**: Simple API for adding new tasks with configurable intervals
+- **Dynamic Control**: Enable/disable tasks at runtime
+- **Interval Management**: Change task execution frequency on the fly
+- **Status Monitoring**: View task status and configuration
+- **Automatic Lifecycle**: Tasks are automatically managed and executed
+
+## Service Interface Integration
+
+Services now implement a unified interface for both endpoint and task registration:
+
+```cpp
+class MyService : public Service {
+public:
+    void registerEndpoints(ApiServer& api) override {
+        // Register HTTP endpoints
+        api.registerEndpoint("/api/my/status", HTTP_GET, 
+            [this](AsyncWebServerRequest* request) { handleStatus(request); });
+    }
+    
+    void registerTasks(TaskManager& taskManager) override {
+        // Register background tasks
+        taskManager.registerTask("my_heartbeat", 2000, 
+            [this]() { sendHeartbeat(); });
+        taskManager.registerTask("my_maintenance", 30000, 
+            [this]() { performMaintenance(); });
+    }
+    
+    const char* getName() const override { return "MyService"; }
+};
+```
+
+## Basic Usage
+
+```cpp
+#include "TaskManager.h"
+
+// Create task manager
+TaskManager taskManager(ctx);
+
+// Register tasks
+taskManager.registerTask("heartbeat", 2000, heartbeatFunction);
+taskManager.registerTask("maintenance", 30000, maintenanceFunction);
+
+// Initialize and start all tasks
+taskManager.initialize();
+```
+
+## Service Lifecycle
+
+The Spore framework automatically manages service registration and task lifecycle:
+
+### Service Registration Process
+
+1. **Service Creation**: Services are created with required dependencies (NodeContext, TaskManager, etc.)
+2. **Service Registration**: Services are registered with the Spore framework via `spore.registerService()`
+3. **Endpoint Registration**: When `spore.begin()` is called, `registerEndpoints()` is called for each service
+4. **Task Registration**: Simultaneously, `registerTasks()` is called for each service
+5. **Task Initialization**: The TaskManager initializes all registered tasks
+6. **Execution**: Tasks run in the main loop when their intervals elapse
+
+### Framework Integration
+
+```cpp
+void setup() {
+    spore.setup();
+    
+    // Create service with dependencies
+    MyService* service = new MyService(spore.getContext(), spore.getTaskManager());
+    
+    // Register service (endpoints and tasks will be registered when begin() is called)
+    spore.registerService(service);
+    
+    // This triggers registerEndpoints() and registerTasks() for all services
+    spore.begin();
+}
+```
+
+### Dynamic Service Addition
+
+Services can be added after the framework has started:
+
+```cpp
+// Add service to running framework
+MyService* newService = new MyService(spore.getContext(), spore.getTaskManager());
+spore.registerService(newService);  // Immediately registers endpoints and tasks
+```
+
+## Task Registration Methods
+
+### Using std::bind with Member Functions (Recommended)
+
+```cpp
+#include <functional>
+#include "TaskManager.h"
+
+class MyService {
+public:
+    void sendHeartbeat() {
+        Serial.println("Service heartbeat");
+    }
+    
+    void performMaintenance() {
+        Serial.println("Running maintenance");
+    }
+};
+
+MyService service;
+TaskManager taskManager(ctx);
+
+// Register member functions using std::bind
+taskManager.registerTask("heartbeat", 2000, 
+                       std::bind(&MyService::sendHeartbeat, &service));
+taskManager.registerTask("maintenance", 30000, 
+                       std::bind(&MyService::performMaintenance, &service));
+
+// Initialize and start all tasks
+taskManager.initialize();
+```
+
+### Using Lambda Functions
+
+```cpp
+// Register lambda functions directly
+taskManager.registerTask("counter", 1000, []() {
+    static int count = 0;
+    Serial.printf("Count: %d\n", ++count);
+});
+
+// Lambda with capture
+int threshold = 100;
+taskManager.registerTask("monitor", 5000, [&threshold]() {
+    if (ESP.getFreeHeap() < threshold) {
+        Serial.println("Low memory warning!");
+    }
+});
+```
+
+### Complex Task Registration
+
+```cpp
+class NetworkManager {
+public:
+    void checkConnection() { /* ... */ }
+    void sendData(String data) { /* ... */ }
+};
+
+NetworkManager network;
+
+// Multiple operations in one task
+taskManager.registerTask("network_ops", 3000, 
+                       std::bind([](NetworkManager* net) {
+                           net->checkConnection();
+                           net->sendData("status_update");
+                       }, &network));
+```
+
+## Task Control API
+
+### Basic Operations
+
+```cpp
+// Enable/disable tasks
+taskManager.enableTask("heartbeat");
+taskManager.disableTask("maintenance");
+
+// Change intervals
+taskManager.setTaskInterval("heartbeat", 5000);  // 5 seconds
+
+// Check status
+bool isRunning = taskManager.isTaskEnabled("heartbeat");
+unsigned long interval = taskManager.getTaskInterval("heartbeat");
+
+// Print all task statuses
+taskManager.printTaskStatus();
+```
+
+### Task Lifecycle Management
+
+```cpp
+// Start/stop tasks
+taskManager.startTask("heartbeat");
+taskManager.stopTask("discovery");
+
+// Bulk operations
+taskManager.enableAllTasks();
+taskManager.disableAllTasks();
+```
+
+## Task Configuration Options
+
+When registering tasks, you can specify:
+
+- **Name**: Unique identifier for the task
+- **Interval**: Execution frequency in milliseconds
+- **Callback**: Function, bound method, or lambda to execute
+- **Enabled**: Whether the task starts enabled (default: true)
+- **AutoStart**: Whether to start automatically (default: true)
+
+```cpp
+// Traditional function
+taskManager.registerTask("delayed_task", 5000, taskFunction, true, false);
+
+// Member function with std::bind
+taskManager.registerTask("service_task", 3000, 
+                       std::bind(&Service::method, &instance), true, false);
+
+// Lambda function
+taskManager.registerTask("lambda_task", 2000, 
+                       []() { Serial.println("Lambda!"); }, true, false);
+```
+
+## Adding Custom Tasks
+
+### Method 1: Service Interface (Recommended)
+
+1. **Create your service class implementing the Service interface**:
+   ```cpp
+   class SensorService : public Service {
+   public:
+       SensorService(NodeContext& ctx, TaskManager& taskManager) 
+           : ctx(ctx), taskManager(taskManager) {}
+       
+       void registerEndpoints(ApiServer& api) override {
+           api.registerEndpoint("/api/sensor/status", HTTP_GET,
+               [this](AsyncWebServerRequest* request) { handleStatus(request); });
+       }
+       
+       void registerTasks(TaskManager& taskManager) override {
+           taskManager.registerTask("temp_read", 1000, 
+               [this]() { readTemperature(); });
+           taskManager.registerTask("calibrate", 60000, 
+               [this]() { calibrateSensors(); });
+       }
+       
+       const char* getName() const override { return "SensorService"; }
+       
+   private:
+       NodeContext& ctx;
+       TaskManager& taskManager;
+       
+       void readTemperature() {
+           // Read sensor logic
+           Serial.println("Reading temperature");
+       }
+       
+       void calibrateSensors() {
+           // Calibration logic
+           Serial.println("Calibrating sensors");
+       }
+       
+       void handleStatus(AsyncWebServerRequest* request) {
+           // Handle status request
+       }
+   };
+   ```
+
+2. **Register with Spore framework**:
+   ```cpp
+   void setup() {
+       spore.setup();
+       
+       SensorService* sensorService = new SensorService(spore.getContext(), spore.getTaskManager());
+       spore.registerService(sensorService);
+       
+       spore.begin();  // This will call registerTasks() automatically
+   }
+   ```
+
+### Method 2: Direct TaskManager Registration
+
+1. **Create your service class**:
+   ```cpp
+   class SensorService {
+   public:
+       void readTemperature() {
+           // Read sensor logic
+           Serial.println("Reading temperature");
+       }
+       
+       void calibrateSensors() {
+           // Calibration logic
+           Serial.println("Calibrating sensors");
+       }
+   };
+   ```
+
+2. **Register with TaskManager**:
+   ```cpp
+   SensorService sensors;
+   
+   taskManager.registerTask("temp_read", 1000, 
+                          std::bind(&SensorService::readTemperature, &sensors));
+   taskManager.registerTask("calibrate", 60000, 
+                          std::bind(&SensorService::calibrateSensors, &sensors));
+   ```
+
+### Method 3: Traditional Functions
+
+1. **Define your task function**:
+   ```cpp
+   void myCustomTask() {
+       // Your task logic here
+       Serial.println("Custom task executed");
+   }
+   ```
+
+2. **Register with TaskManager**:
+   ```cpp
+   taskManager.registerTask("my_task", 10000, myCustomTask);
+   ```
+
+## Enhanced TaskManager Capabilities
+
+### Task Status Monitoring
+- **Real-time Status**: Check enabled/disabled state and running status
+- **Performance Metrics**: Monitor execution intervals and timing
+- **System Integration**: View task status alongside system resources
+- **Bulk Operations**: Get status of all tasks at once
+
+### Task Control Features
+- **Runtime Control**: Enable/disable tasks without restart
+- **Dynamic Intervals**: Change task execution frequency on-the-fly
+- **Individual Status**: Get detailed information about specific tasks
+- **Health Monitoring**: Track task health and system resources
+
+## Remote Task Management
+
+The TaskManager integrates with the API server to provide comprehensive remote task control and monitoring.
+
+### Task Status Overview
+
+Get a complete overview of all tasks and system status:
+
+```bash
+# Get comprehensive task status
+curl http://192.168.1.100/api/tasks/status
+```
+
+**Response includes:**
+- **Summary**: Total task count and active task count
+- **Task Details**: Individual status for each task (name, interval, enabled, running, auto-start)
+- **System Info**: Free heap memory and uptime
+
+**Example Response:**
+```json
+{
+  "summary": {
+    "totalTasks": 6,
+    "activeTasks": 5
+  },
+  "tasks": [
+    {
+      "name": "discovery_send",
+      "interval": 1000,
+      "enabled": true,
+      "running": true,
+      "autoStart": true
+    },
+    {
+      "name": "heartbeat",
+      "interval": 2000,
+      "enabled": true,
+      "running": true,
+      "autoStart": true
+    }
+  ],
+  "system": {
+    "freeHeap": 48748,
+    "uptime": 12345
+  }
+}
+```
+
+### Individual Task Control
+
+Control individual tasks with various actions:
+
+```bash
+# Control tasks
+curl -X POST http://192.168.1.100/api/tasks/control \
+  -d "task=heartbeat&action=disable"
+
+# Get detailed status for a specific task
+curl -X POST http://192.168.1.100/api/tasks/control \
+  -d "task=discovery_send&action=status"
+```
+
+**Available Actions:**
+- `enable` - Enable a task
+- `disable` - Disable a task  
+- `start` - Start a task
+- `stop` - Stop a task
+- `status` - Get detailed status for a specific task
+
+**Task Status Response:**
+```json
+{
+  "success": true,
+  "message": "Task status retrieved",
+  "task": "discovery_send",
+  "action": "status",
+  "taskDetails": {
+    "name": "discovery_send",
+    "enabled": true,
+    "running": true,
+    "interval": 1000,
+    "system": {
+      "freeHeap": 48748,
+      "uptime": 12345
+    }
+  }
+}
+```
+
+## Performance Considerations
+
+- `std::bind` creates a callable object that may have a small overhead compared to direct function pointers
+- For high-frequency tasks, consider the performance impact
+- The overhead is typically negligible for most embedded applications
+- The TaskManager stores bound functions efficiently in a registry
+
+## Best Practices
+
+1. **Use Service Interface**: Implement the Service interface for clean integration with the framework
+2. **Group related tasks**: Register multiple related operations in a single service
+3. **Monitor task health**: Use the status API to monitor task performance
+4. **Plan intervals carefully**: Balance responsiveness with system resources
+5. **Use descriptive names**: Make task names clear and meaningful
+6. **Separate concerns**: Use registerEndpoints() for HTTP API and registerTasks() for background work
+7. **Dependency injection**: Pass required dependencies (NodeContext, TaskManager) to service constructors
+
+## Migration to Service Interface
+
+### Before (manual task registration in constructor):
+```cpp
+class MyService : public Service {
+public:
+    MyService(TaskManager& taskManager) : taskManager(taskManager) {
+        // Tasks registered in constructor
+        taskManager.registerTask("heartbeat", 2000, [this]() { sendHeartbeat(); });
+    }
+    
+    void registerEndpoints(ApiServer& api) override {
+        // Only endpoints registered here
+    }
+};
+```
+
+### After (using Service interface):
+```cpp
+class MyService : public Service {
+public:
+    MyService(TaskManager& taskManager) : taskManager(taskManager) {
+        // No task registration in constructor
+    }
+    
+    void registerEndpoints(ApiServer& api) override {
+        // Register HTTP endpoints
+        api.registerEndpoint("/api/my/status", HTTP_GET, 
+            [this](AsyncWebServerRequest* request) { handleStatus(request); });
+    }
+    
+    void registerTasks(TaskManager& taskManager) override {
+        // Register background tasks
+        taskManager.registerTask("heartbeat", 2000, [this]() { sendHeartbeat(); });
+    }
+    
+    const char* getName() const override { return "MyService"; }
+};
+```
+
+### Migration from Wrapper Functions
+
+### Before (with wrapper functions):
+```cpp
+void discoverySendTask() { cluster.sendDiscovery(); }
+void clusterListenTask() { cluster.listen(); }
+
+taskManager.registerTask("discovery_send", interval, discoverySendTask);
+taskManager.registerTask("cluster_listen", interval, clusterListenTask);
+```
+
+### After (with std::bind):
+```cpp
+taskManager.registerTask("discovery_send", interval, 
+                       std::bind(&ClusterManager::sendDiscovery, &cluster));
+taskManager.registerTask("cluster_listen", interval, 
+                       std::bind(&ClusterManager::listen, &cluster));
+```
+
+## Compatibility
+
+- The new Service interface is fully backward compatible
+- Existing code using direct TaskManager registration will continue to work
+- You can mix Service interface and direct registration in the same project
+- All existing TaskManager methods remain unchanged
+- The Service interface provides a cleaner, more organized approach for framework integration

+# SPORE WiFi Configuration Process
+
+## Overview
+
+SPORE implements a WiFi configuration system that handles initial setup, runtime reconfiguration, and automatic fallback mechanisms. The system supports both Station (STA) and Access Point (AP) modes with seamless switching between them.
+
+## WiFi Configuration Architecture
+
+### Core Components
+
+- **`NetworkManager`**: Handles WiFi operations and configuration
+- **`NetworkService`**: Provides HTTP API endpoints for WiFi management
+- **`Config`**: Stores WiFi credentials and connection parameters
+- **LittleFS**: Persistent storage for WiFi configuration
+- **ESP8266 WiFi Library**: Low-level WiFi operations
+
+### Configuration Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `wifi_ssid` | String | "shroud" | Network SSID for connection |
+| `wifi_password` | String | "th3r31sn0sp00n" | Network password |
+| `wifi_connect_timeout_ms` | uint32_t | 15000 | Connection timeout (15 seconds) |
+| `wifi_retry_delay_ms` | uint32_t | 500 | Delay between connection attempts |
+
+## WiFi Configuration Lifecycle
+
+### 1. Boot Process
+
+```mermaid
+graph TD
+    A[System Boot] --> B[Initialize LittleFS]
+    B --> C[Load Configuration]
+    C --> D[Initialize WiFi Mode]
+    D --> E[Set Hostname from MAC]
+    E --> F[Attempt STA Connection]
+    F --> G{Connection Successful?}
+    G -->|Yes| H[STA Mode Active]
+    G -->|No| I[Switch to AP Mode]
+    I --> J[Create Access Point]
+    J --> K[AP Mode Active]
+    H --> L[Start UDP Services]
+    K --> L
+    L --> M[Initialize Node Context]
+    M --> N[Start Cluster Services]
+```
+
+**Detailed Boot Sequence:**
+
+1. **LittleFS Initialization**
+   ```cpp
+   if (!LittleFS.begin()) {
+       LOG_WARN("Config", "Failed to initialize LittleFS, using defaults");
+       setDefaults();
+       return;
+   }
+   ```
+
+2. **Configuration Loading**
+   - Load WiFi credentials from `/config.json`
+   - Fall back to defaults if file doesn't exist
+   - Validate configuration parameters
+
+3. **WiFi Mode Initialization**
+   ```cpp
+   WiFi.mode(WIFI_STA);
+   WiFi.begin(ctx.config.wifi_ssid.c_str(), ctx.config.wifi_password.c_str());
+   ```
+
+4. **Hostname Generation**
+   ```cpp
+   void NetworkManager::setHostnameFromMac() {
+       uint8_t mac[6];
+       WiFi.macAddress(mac);
+       char buf[32];
+       sprintf(buf, "esp-%02X%02X%02X%02X%02X%02X", 
+               mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);
+       WiFi.hostname(buf);
+       ctx.hostname = String(buf);
+   }
+   ```
+
+5. **Connection Attempt**
+   ```cpp
+   unsigned long startAttemptTime = millis();
+   while (WiFi.status() != WL_CONNECTED && 
+          millis() - startAttemptTime < ctx.config.wifi_connect_timeout_ms) {
+       delay(ctx.config.wifi_retry_delay_ms);
+   }
+   ```
+
+6. **Fallback to AP Mode**

+```
+
+**Runtime Reconfiguration Process:**
+
+1. **API Request Validation**
+   ```cpp
+   if (!request->hasParam("ssid", true) || !request->hasParam("password", true)) {
+       request->send(400, "application/json", "{\"error\": \"Missing required parameters\"}");
+       return;
+   }
+   ```
+
+2. **Configuration Update**
+   ```cpp
+   void NetworkManager::setWiFiConfig(const String& ssid, const String& password,
+                                      uint32_t connect_timeout_ms, uint32_t retry_delay_ms) {
+       ctx.config.wifi_ssid = ssid;
+       ctx.config.wifi_password = password;
+       ctx.config.wifi_connect_timeout_ms = connect_timeout_ms;
+       ctx.config.wifi_retry_delay_ms = retry_delay_ms;
+   }
+   ```
+
+3. **Persistent Storage**
+   ```cpp
+   bool configSaved = networkManager.saveConfig();
+   if (!configSaved) {
+       LOG_WARN("NetworkService", "Failed to save WiFi configuration to persistent storage");
+   }
+   ```
+
+4. **Restart Scheduling**
+   ```cpp
+   request->onDisconnect([this]() {
+       LOG_INFO("NetworkService", "Restarting node to apply WiFi configuration...");
+       delay(100); // Give time for response to be sent
+       networkManager.restartNode();
+   });
+   ```
+
+## WiFi Modes
+
+### Station Mode (STA)
+
+**Purpose**: Connect to existing WiFi network as a client
+
+**Configuration**:
+- SSID and password required
+- Automatic IP assignment via DHCP
+- Hostname set from MAC address
+- UDP services on configured port
+
+**Connection Process**:
+1. Set WiFi mode to STA
+2. Begin connection with credentials
+3. Wait for connection with timeout
+4. Set hostname and start services
+
+### Access Point Mode (AP)
+
+**Purpose**: Create WiFi hotspot when STA connection fails
+
+**Configuration**:
+- Uses configured SSID/password for AP
+- Fixed IP address (usually 192.168.4.1)
+- Allows other devices to connect
+- Maintains cluster functionality
+
+**AP Creation Process**:
+1. Switch WiFi mode to AP
+2. Create soft access point
+3. Set AP IP address
+4. Start services on AP IP

+## WiFi Scanning Process
+
+### Scanning Implementation
+
+```cpp
+void NetworkManager::scanWifi() {
+    if (!isScanning) {
+        isScanning = true;
+        LOG_INFO("WiFi", "Starting WiFi scan...");
+        WiFi.scanNetworksAsync([this](int networksFound) {
+            LOG_INFO("WiFi", "Scan completed, found " + String(networksFound) + " networks");
+            this->processAccessPoints();
+            this->isScanning = false;
+        }, true);
+    }
+}
+```
+
+### Access Point Processing
+
+```cpp
+void NetworkManager::processAccessPoints() {
+    int numNetworks = WiFi.scanComplete();
+    if (numNetworks <= 0) return;
+
+    accessPoints.clear();
+    for (int i = 0; i < numNetworks; i++) {
+        AccessPoint ap;
+        ap.ssid = WiFi.SSID(i);
+        ap.rssi = WiFi.RSSI(i);
+        ap.encryptionType = WiFi.encryptionType(i);
+        ap.channel = WiFi.channel(i);
+        ap.isHidden = ap.ssid.length() == 0;
+        
+        uint8_t* newBssid = new uint8_t[6];
+        memcpy(newBssid, WiFi.BSSID(i), 6);
+        ap.bssid = newBssid;
+
+        accessPoints.push_back(ap);
+    }
+    WiFi.scanDelete();
+}
+```
+
+## Error Handling
+
+### Connection Failures
+
+| Error Type | Handling | Recovery |
+|------------|----------|----------|
+| **Invalid Credentials** | Log error, switch to AP mode | Manual reconfiguration via API |
+| **Network Unavailable** | Log warning, switch to AP mode | Automatic retry on next boot |
+| **Timeout** | Log timeout, switch to AP mode | Increase timeout or check network |
+| **Hardware Failure** | Log error, continue in AP mode | Hardware replacement required |
+
+### API Error Responses
+
+```json
+{
+  "error": "Missing required parameters",
+  "status": "error"
+}
+```
+
+```json
+{
+  "error": "Failed to save configuration",
+  "status": "error",
+  "config_saved": false
+}
+```
+
+## Security Considerations
+
+### Current Implementation
+
+- **Plain Text Storage**: WiFi passwords stored unencrypted
+- **Local Network Only**: No internet exposure
+- **No Authentication**: API access without authentication
+- **MAC-based Hostnames**: Predictable hostname generation
+
+### Security Best Practices
+
+1. **Network Isolation**: Keep SPORE devices on isolated network
+2. **Strong Passwords**: Use complex WiFi passwords
+3. **Regular Updates**: Keep firmware updated
+4. **Access Control**: Implement network-level access control
+
+### Future Security Enhancements
+
+- **Password Encryption**: Encrypt stored WiFi credentials
+- **API Authentication**: Add authentication to configuration API
+- **Certificate-based Security**: Implement TLS/SSL
+- **Access Control Lists**: Role-based configuration access
+
+## Troubleshooting
+
+### Common Issues
+
+1. **WiFi Connection Fails**
+   - Check SSID and password
+   - Verify network availability
+   - Check signal strength
+   - Increase connection timeout
+
+2. **Configuration Not Persisting**
+   - Check LittleFS initialization
+   - Verify file write permissions
+   - Monitor available flash space
+
+3. **AP Mode Not Working**
+   - Check AP credentials
+   - Verify IP address assignment
+   - Check for IP conflicts
+
+4. **Scan Not Finding Networks**
+   - Wait for scan completion
+   - Check WiFi hardware
+   - Verify scan permissions
+
+### Debug Commands
+
+```bash
+# Check WiFi status
+curl -s http://192.168.1.100/api/network/status | jq '.wifi'
+
+# Scan for networks
+curl -X POST http://192.168.1.100/api/network/wifi/scan
+
+# View scan results
+curl -s http://192.168.1.100/api/network/wifi/scan | jq '.'
+
+# Test configuration
+curl -X POST http://192.168.1.100/api/network/wifi/config \
+  -d "ssid=TestNetwork&password=testpass"
+```
+
+### Log Analysis
+
+**Successful Connection**:
+```
+[INFO] WiFi: Connected to AP, IP: 192.168.1.100
+[INFO] WiFi: Hostname set to: esp-AABBCCDDEEFF
+[INFO] WiFi: UDP listening on port 4210
+```
+
+**Connection Failure**:
+```
+[WARN] WiFi: Failed to connect to AP. Creating AP...
+[INFO] WiFi: AP created, IP: 192.168.4.1
+```
+
+**Configuration Update**:
+```
+[INFO] NetworkService: Restarting node to apply WiFi configuration...
+[INFO] WiFi: Connecting to AP...
+```
+
+## Performance Considerations
+
+### Connection Time
+
+- **STA Connection**: 5-15 seconds typical
+- **AP Creation**: 1-3 seconds
+- **Scan Duration**: 5-10 seconds
+- **Configuration Save**: 100-500ms
+
+### Memory Usage
+
+- **WiFi Stack**: ~20-30KB RAM
+- **Scan Results**: ~1KB per network
+- **Configuration**: ~200 bytes
+- **API Buffers**: ~2-4KB
+
+### Network Overhead
+
+- **Scan Packets**: Minimal impact
+- **Configuration API**: ~500 bytes per request
+- **Status Updates**: ~200 bytes per response
+
+## Best Practices
+
+### Configuration Management
+
+1. **Use Strong Passwords**: Implement password complexity requirements
+2. **Set Appropriate Timeouts**: Balance connection speed vs reliability
+3. **Monitor Connection Quality**: Track RSSI and connection stability
+4. **Implement Retry Logic**: Handle temporary network issues
+5. **Log Configuration Changes**: Audit trail for troubleshooting
+
+### Development Guidelines
+
+1. **Handle All Error Cases**: Implement comprehensive error handling
+2. **Provide Clear Feedback**: Inform users of connection status
+3. **Optimize Scan Frequency**: Balance discovery vs performance
+4. **Test Fallback Scenarios**: Ensure AP mode works correctly
+5. **Document Configuration Options**: Clear parameter documentation

+# NeoPattern Service for Spore Framework
+
+This example demonstrates how to integrate a NeoPixel pattern service with the Spore framework. It provides a comprehensive LED strip control system with multiple animation patterns and REST API endpoints.
+
+## Features
+
+- **Multiple Animation Patterns**: Rainbow cycle, theater chase, color wipe, scanner, fade, and fire effects
+- **REST API Control**: Full HTTP API for pattern control and configuration
+- **Real-time Updates**: Smooth pattern transitions and real-time parameter changes
+- **State Management**: Persistent state with JSON serialization
+- **Spore Integration**: Built on the Spore framework for networking and task management
+
+## Hardware Requirements
+
+- ESP32 or compatible microcontroller
+- NeoPixel LED strip (WS2812B or compatible)
+- Appropriate power supply for your LED strip
+
+## Configuration
+
+Edit `NeoPixelConfig.h` to configure your setup:
+
+```cpp
+static constexpr int DEFAULT_PIN = 2;
+static constexpr int DEFAULT_LENGTH = 8;
+static constexpr int DEFAULT_BRIGHTNESS = 100;
+static constexpr int DEFAULT_UPDATE_INTERVAL = 100;
+static constexpr int DEFAULT_COLOR = 0xFF0000; // Red
+```
+
+## API Endpoints
+
+### Status Information
+- `GET /api/neopattern/status` - Get current status and configuration
+- `GET /api/neopattern/patterns` - List available patterns
+
+### Pattern Control
+- `POST /api/neopattern` - Control pattern parameters
+  - `pattern`: Pattern name (none, rainbow_cycle, theater_chase, color_wipe, scanner, fade, fire)
+  - `color`: Primary color (hex string like "#FF0000" or "0xFF0000")
+  - `color2`: Secondary color for two-color patterns
+  - `brightness`: Brightness level (0-255)
+  - `total_steps`: Number of steps for patterns
+  - `direction`: Pattern direction (forward, reverse)
+  - `interval`: Update interval in milliseconds
+
+### State Management
+- `POST /api/neopattern/state` - Set complete state via JSON
+
+## Example API Usage
+
+### Set a rainbow cycle pattern
+```bash
+curl -X POST http://esp32-ip/api/neopattern \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "pattern=rainbow_cycle&interval=50"
+```
+
+### Set custom colors for theater chase
+```bash
+curl -X POST http://esp32-ip/api/neopattern \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "pattern=theater_chase&color=0xFF0000&color2=0x0000FF&brightness=150"
+```
+
+### Set complete state via JSON
+```bash
+curl -X POST http://esp32-ip/api/neopattern/state \
+  -H "Content-Type: application/json" \
+  -d '{
+    "pattern": 3,
+    "color": 16711680,
+    "color2": 255,
+    "totalSteps": 32,
+    "brightness": 128
+  }'
+```
+
+## Available Patterns
+
+1. **none** - Static color display
+2. **rainbow_cycle** - Smooth rainbow cycling
+3. **theater_chase** - Moving dots with two colors
+4. **color_wipe** - Progressive color filling
+5. **scanner** - Scanning light effect
+6. **fade** - Smooth color transition
+7. **fire** - Fire simulation effect
+
+## Building and Flashing
+
+1. Install PlatformIO
+2. Configure your `platformio.ini` to include the Spore framework
+3. Build and upload:
+
+```bash
+pio run -t upload
+```
+
+## Integration with Spore Framework
+
+This service integrates with the Spore framework by:
+
+- Extending the `Service` base class
+- Using `TaskManager` for pattern updates
+- Registering REST API endpoints with `ApiServer`
+- Following Spore's logging and configuration patterns
+
+The service automatically registers itself with the Spore framework and provides all functionality through the standard Spore API infrastructure.
+
+## Customization
+
+To add new patterns:
+
+1. Add the pattern enum to `NeoPatternService.h`
+2. Implement the pattern logic in `NeoPattern.cpp`
+3. Add the pattern updater to `registerPatterns()` in `NeoPatternService.cpp`
+4. Update the pattern mapping in `nameToPatternMap`
+
+## Troubleshooting
+
+- **LEDs not lighting**: Check wiring and power supply
+- **Patterns not updating**: Verify the update interval and task registration
+- **API not responding**: Check network configuration and Spore framework setup
+- **Memory issues**: Reduce LED count or pattern complexity
+
+## Dependencies
+
+- Spore Framework
+- Adafruit NeoPixel library
+- ArduinoJson
+- ESP32 Arduino Core

+# PixelStream Example
+
+This example demonstrates how to consume the `udp/raw` cluster event and drive a NeoPixel strip or matrix directly from streamed RGB data. Frames are provided as hex encoded byte triplets (`RRGGBB` per pixel).
+
+## Features
+
+- Subscribes to `udp/raw` via `NodeContext::on`.
+- Converts incoming frames into pixel colors for strips or matrices.
+- Supports serpentine (zig-zag) matrix wiring.
+
+## Payload Format
+
+Each packet is expected to be `RAW:` followed by `pixelCount * 3 * 2` hexadecimal characters. For example, for 8 pixels:
+
+```
+RAW:FF0000FF0000FF0000FF0000FF0000FF0000FF0000FF0000FF0000
+```
+
+## Usage
+
+### Strip Mode
+
+Upload the example with `PIXEL_MATRIX_WIDTH` set to 0 (default). Send frames containing `PIXEL_COUNT * 3` bytes as hex.
+
+### Matrix Mode
+
+Set `PIXEL_MATRIX_WIDTH` to the number of columns. The controller remaps even/odd rows to support serpentine wiring.
+
+## Configuration
+
+Adjust `PIXEL_PIN`, `PIXEL_COUNT`, `PIXEL_BRIGHTNESS`, `PIXEL_MATRIX_WIDTH`, `PIXEL_MATRIX_SERPENTINE`, and `PIXEL_TYPE` through build defines or editing `main.cpp`.
+

+# Relay Service Example
+
+A minimal example that demonstrates the Spore framework with a custom RelayService and web interface. The Spore framework automatically handles all core functionality (WiFi, clustering, API server, task management) while allowing easy registration of custom services.
+
+## Features
+
+- **API Control**: RESTful API endpoints for programmatic control
+- **Web Interface**: Beautiful web UI for manual control at `http://<device-ip>/relay.html`
+- **Real-time Status**: Live status updates and visual feedback
+- **Toggle Functionality**: One-click toggle between ON/OFF states
+
+- Default relay pin: `GPIO0` (ESP-01). Override with `-DRELAY_PIN=<pin>`.
+- WiFi and API port are configured in `src/Config.cpp`.
+
+## Spore Framework Usage
+
+This example demonstrates the simplified Spore framework approach:
+
+```cpp
+#include <Arduino.h>
+#include "Spore.h"
+#include "RelayService.h"
+
+Spore spore({
+    {"app", "relay"},
+    {"device", "actuator"},
+    {"pin", String(RELAY_PIN)}
+});
+
+RelayService* relayService = nullptr;
+
+void setup() {
+    spore.setup();
+    
+    relayService = new RelayService(spore.getContext(), spore.getTaskManager(), RELAY_PIN);
+    spore.registerService(relayService);
+    
+    spore.begin();
+}
+
+void loop() {
+    spore.loop();
+}
+```
+
+The Spore framework automatically provides:
+- WiFi connectivity management
+- Cluster discovery and management  
+- REST API server with core endpoints
+- Task scheduling and execution
+- Node status monitoring
+- Static file serving for web interfaces (core service)
+
+## Build & Upload
+
+- ESP‑01S:
+```bash
+pio run -e esp01_1m_relay -t upload
+```
+- D1 Mini:
+```bash
+pio run -e d1_mini_relay -t upload
+```
+
+Monitor serial logs:
+```bash
+pio device monitor -b 115200
+```
+
+Assume the device IP is 192.168.1.50 below (replace with your device's IP shown in serial output).
+
+## Web Interface
+
+The web interface is located in the `data/` folder and will be served by the core StaticFileService.
+
+Access the web interface at: `http://192.168.1.50/relay.html`
+
+The web interface provides:
+- Visual status indicator (red for OFF, green for ON)
+- Turn ON/OFF buttons
+- Toggle button for quick switching
+- Real-time status updates every 2 seconds
+- Uptime display
+- Error handling and user feedback
+
+## Relay API
+
+- Get relay status
+```bash
+curl http://192.168.1.50/api/relay/status
+```
+
+- Turn relay ON
+```bash
+curl -X POST http://192.168.1.50/api/relay -d state=on
+```
+
+- Turn relay OFF
+```bash
+curl -X POST http://192.168.1.50/api/relay -d state=off
+```
+
+- Toggle relay
+```bash
+curl -X POST http://192.168.1.50/api/relay -d state=toggle
+```
+
+Notes:
+- Requests use `application/x-www-form-urlencoded` by default when using `curl -d`.
+
+## Task Management (optional)
+The example registers a periodic task `relay_status_print` that logs the current relay state.
+
+- Fetch all task statuses
+```bash
+curl http://192.168.1.50/api/tasks/status
+```
+
+- Query a specific task status
+```bash
+curl -X POST http://192.168.1.50/api/tasks/control \
+  -d task=relay_status_print -d action=status
+```
+
+- Enable / Disable the task
+```bash
+curl -X POST http://192.168.1.50/api/tasks/control \
+  -d task=relay_status_print -d action=enable
+
+curl -X POST http://192.168.1.50/api/tasks/control \
+  -d task=relay_status_print -d action=disable
+```
+
+## General System Endpoints (optional)
+- Node status
+```bash
+curl http://192.168.1.50/api/node/status
+```
+
+- Restart device
+```bash
+curl -X POST http://192.168.1.50/api/node/restart
+```

+# Test Scripts
 
-This directory is intended for PlatformIO Test Runner and project tests.
+This directory contains JavaScript test scripts to interact with the Spore device, primarily for testing cluster event broadcasting.
 
-Unit Testing is a software testing method by which individual units of
-source code, sets of one or more MCU program modules together with associated
-control data, usage procedures, and operating procedures, are tested to
-determine whether they are fit for use. Unit testing finds problems early
-in the development cycle.
+## Prerequisites
+
+These scripts require [Node.js](https://nodejs.org/) to be installed on your system.
+
+## How to Run
+
+### 1. HTTP Cluster Broadcast Color (`test/http-cluster-broadcast-color.js`)
+
+This script sends HTTP POST requests to the `/api/cluster/event` endpoint on your Spore device. It broadcasts NeoPattern color changes across the cluster every 5 seconds.
+
+**Usage:**
+```
+node test/http-cluster-broadcast-color.js <device-ip>
+```
+Example:
+```
+node test/http-cluster-broadcast-color.js 10.0.1.53
+```
+This will broadcast `{ event: "api/neopattern/color", data: { color: "#RRGGBB", brightness: 128 } }` every 5 seconds to the cluster via `/api/cluster/event`.
+
+### 2. WS Local Color Setter (`test/ws-color-client.js`)
+
+Connects to the device WebSocket (`/ws`) and sets a solid color locally (non-broadcast) every 5 seconds by firing `api/neopattern/color`.
+
+**Usage:**
+```
+node test/ws-color-client.js ws://<device-ip>/ws
+```
+Example:
+```
+node test/ws-color-client.js ws://10.0.1.53/ws
+```
+
+### 3. WS Cluster Broadcast Color (`test/ws-cluster-broadcast-color.js`)
+
+Connects to the device WebSocket (`/ws`) and broadcasts a color change to all peers every 5 seconds by firing `cluster/broadcast` with the proper envelope.
+
+**Usage:**
+```
+node test/ws-cluster-broadcast-color.js ws://<device-ip>/ws
+```
+Example:
+```
+node test/ws-cluster-broadcast-color.js ws://10.0.1.53/ws
+```
+
+### 4. WS Cluster Broadcast Rainbow (`test/ws-cluster-broadcast-rainbow.js`)
+
+Broadcasts a smooth rainbow color transition over WebSocket using `cluster/broadcast` and the `api/neopattern/color` event. Update rate defaults to `UPDATE_RATE` in the script (e.g., 100 ms).
+
+**Usage:**
+```
+node test/ws-cluster-broadcast-rainbow.js ws://<device-ip>/ws
+```
+Example:
+```
+node test/ws-cluster-broadcast-rainbow.js ws://10.0.1.53/ws
+```
+Note: Very fast update intervals (e.g., 10 ms) may saturate links or the device.
