docs(sports): address review — test matrix, and compatible_versions

Both CodeRabbit findings on #427 hold up against the code; one sub-point was
already moot.

1. The compatibility regression test was described as one case (bundled copy
   removed on an old core) when it needs four. The case that actually matters
   is the one that was missing: an adopted plugin loading *with* its bundled
   copy on an old core, which is the entire basis for claiming B5 is safe to
   run ahead of the gate. Now a 2x2 table.

   The assertion was also wrong. "Fails loudly and specifically" is
   aspirational -- PluginManager.load_plugin catches ModuleNotFoundError, so
   nothing propagates and it fails into PluginState.ERROR with one log line.
   A test expecting a raise would pass for the wrong reason. Specified as
   PluginState.ERROR plus the exact missing module path, which is also what
   the rest of this document already says the failure looks like.

2. `compatible_versions` -- not `ledmatrix_min_version` -- is the canonical
   contract: schema/manifest_schema.json requires it, all 42 published
   manifests carry it, and it holds semver ranges ([">=2.0.0"] in 41,
   [">=1.0.0"] in 7-segment-clock). The gate as merged reads only the floor.

   Harmless today: no manifest uses an upper bound, and the two fields agree
   everywhere except 7-segment-clock. But the schema's range syntax permits
   upper bounds, so a plugin declaring ["2.0.0 - 2.9.9"] would be installed on
   3.2.0 regardless. Recorded as a named gap the gate must close before B6,
   and the migration step now has to reconcile both fields across every
   manifest the gate can refuse.

   Skipped, with reason: the finding also asked to migrate the deprecated
   top-level `ledmatrix_version`. No manifest carries it -- verified across
   all 42 -- so there is nothing to migrate.

Documentation only.

+# Cursor Helper Files for LEDMatrix Plugin Development
+
+This directory contains Cursor-specific helper files to assist with plugin development in the LEDMatrix project.
+
+## Files Overview
+
+### `.cursorrules`
+Comprehensive rules file that Cursor uses to understand plugin development patterns, best practices, and workflows. This file is automatically loaded by Cursor and helps guide AI-assisted development.
+
+### `plugins_guide.md`
+Detailed guide covering:
+- Plugin system overview
+- Creating new plugins
+- Running plugins (emulator and hardware)
+- Loading and configuring plugins
+- Development workflow
+- Testing strategies
+- Troubleshooting
+
+### `plugin_templates/`
+Template files for quick plugin creation:
+- `manifest.json.template` - Plugin metadata template
+- `manager.py.template` - Plugin class template
+- `config_schema.json.template` - Configuration schema template
+- `README.md.template` - Plugin documentation template
+- `requirements.txt.template` - Dependencies template
+- `QUICK_START.md` - Quick start guide for using templates
+
+## Quick Reference
+
+### Creating a New Plugin
+
+1. **Using templates** (recommended):
+```bash
+# See QUICK_START.md in plugin_templates/
+cd plugins
+mkdir my-plugin
+cd my-plugin
+cp ../../.cursor/plugin_templates/*.template .
+# Edit files, replacing PLUGIN_ID and other placeholders
+```
+
+2. **Using dev_plugin_setup.sh**:
+```bash
+# Link from GitHub
+./scripts/dev/dev_plugin_setup.sh link-github my-plugin
+
+# Link local repo
+./scripts/dev/dev_plugin_setup.sh link my-plugin /path/to/repo
+```
+
+### Running the Display
+
+```bash
+# Emulator mode (development, no hardware required)
+python3 run.py --emulator
+# (equivalent: EMULATOR=true python3 run.py)
+
+# Hardware (production, requires the rpi-rgb-led-matrix submodule built)
+python3 run.py
+
+# As a systemd service
+sudo systemctl start ledmatrix
+
+# Dev preview server (renders plugins to a browser without running run.py)
+python3 scripts/dev_server.py  # then open http://localhost:5001
+```
+
+The `-e`/`--emulator` CLI flag is defined in `run.py:19-20` and
+sets `os.environ["EMULATOR"] = "true"` before any display imports,
+which `src/display_manager.py:2` then reads to switch between the
+hardware and emulator backends.
+
+### Managing Plugins
+
+```bash
+# List plugins
+./scripts/dev/dev_plugin_setup.sh list
+
+# Check status
+./scripts/dev/dev_plugin_setup.sh status
+
+# Update plugin(s)
+./scripts/dev/dev_plugin_setup.sh update [plugin-name]
+
+# Unlink plugin
+./scripts/dev/dev_plugin_setup.sh unlink <plugin-name>
+```
+
+## Using These Files with Cursor
+
+### `.cursorrules`
+Cursor automatically reads this file to understand:
+- Plugin structure and requirements
+- Development workflows
+- Best practices
+- Common patterns
+- API reference
+
+When asking Cursor to help with plugins, it will use this context to provide better assistance.
+
+### Plugin Templates
+Use templates when creating new plugins:
+1. Copy templates from `.cursor/plugin_templates/`
+2. Replace placeholders (PLUGIN_ID, PluginClassName, etc.)
+3. Customize for your plugin's needs
+4. Follow the guide in `plugins_guide.md`
+
+### Documentation
+Refer to `plugins_guide.md` for:
+- Detailed explanations
+- Troubleshooting steps
+- Best practices
+- Examples and patterns
+
+## Plugin Development Workflow
+
+1. **Plan**: Determine plugin functionality and requirements
+2. **Create**: Use templates or dev_plugin_setup.sh to create plugin structure
+3. **Develop**: Implement plugin logic following BasePlugin interface
+4. **Test**: Test with emulator first, then on hardware
+5. **Configure**: Add plugin config to config/config.json
+6. **Iterate**: Refine based on testing and feedback
+
+## Resources
+
+- **Plugin System**: `src/plugin_system/`
+- **Base Plugin**: `src/plugin_system/base_plugin.py`
+- **Plugin Manager**: `src/plugin_system/plugin_manager.py`
+- **Example Plugins**: see the
+  [`ledmatrix-plugins`](https://github.com/ChuckBuilds/ledmatrix-plugins)
+  repo for canonical sources (e.g. `plugins/hockey-scoreboard/`,
+  `plugins/football-scoreboard/`). Installed plugins land in
+  `plugin-repos/` (default) or `plugins/` (dev fallback).
+- **Architecture Docs**: `docs/PLUGIN_ARCHITECTURE_SPEC.md`
+- **Development Setup**: `scripts/dev/dev_plugin_setup.sh`
+
+## Getting Help
+
+1. Check `plugins_guide.md` for detailed documentation

+# Quick Start: Creating a New Plugin
+
+This guide will help you create a new plugin using the templates in `.cursor/plugin_templates/`.
+
+## Step 1: Create Plugin Directory
+
+```bash
+cd /path/to/LEDMatrix
+mkdir -p plugins/my-plugin
+cd plugins/my-plugin
+```
+
+## Step 2: Copy Templates
+
+```bash
+# Copy all template files
+cp ../../.cursor/plugin_templates/manifest.json.template ./manifest.json
+cp ../../.cursor/plugin_templates/manager.py.template ./manager.py
+cp ../../.cursor/plugin_templates/config_schema.json.template ./config_schema.json
+cp ../../.cursor/plugin_templates/README.md.template ./README.md
+cp ../../.cursor/plugin_templates/requirements.txt.template ./requirements.txt
+```
+
+## Step 3: Customize Files
+
+### manifest.json
+
+Replace placeholders:
+- `PLUGIN_ID` → `my-plugin` (lowercase, use hyphens)
+- `Plugin Name` → Your plugin's display name
+- `PluginClassName` → `MyPlugin` (PascalCase)
+- Update description, author, homepage, etc.
+
+### manager.py
+
+Replace placeholders:
+- `PluginClassName` → `MyPlugin` (must match manifest)
+- Implement `_fetch_data()` method
+- Implement `_render_content()` method
+- Add any custom validation in `validate_config()`
+
+### config_schema.json
+
+Customize:
+- Update description
+- Add/remove configuration properties
+- Set default values
+- Add validation rules
+
+### README.md
+
+Replace placeholders:
+- `PLUGIN_ID` → `my-plugin`
+- `Plugin Name` → Your plugin's name
+- Fill in features, installation, configuration sections
+
+### requirements.txt
+
+Add your plugin's dependencies:
+```txt
+requests>=2.28.0
+pillow>=9.0.0
+```
+
+## Step 4: Enable Plugin
+
+Edit `config/config.json`:
+
+```json
+{
+  "my-plugin": {
+    "enabled": true,
+    "display_duration": 15
+  }
+}
+```
+
+## Step 5: Test Plugin
+
+### Test with Emulator
+
+```bash
+cd /path/to/LEDMatrix
+python run.py --emulator
+```
+
+### Check Plugin Loading
+
+Look for logs like:
+```
+[INFO] Discovered 1 plugin(s)
+[INFO] Loaded plugin: my-plugin v1.0.0
+[INFO] Added plugin mode: my-plugin
+```
+
+### Test Plugin Display
+
+The plugin should appear in the display rotation. Check logs for any errors.
+
+## Step 6: Develop and Iterate
+
+1. Edit `manager.py` to implement your plugin logic
+2. Test with emulator: `python run.py --emulator`
+3. Check logs for errors
+4. Iterate until working correctly
+
+## Step 7: Test on Hardware (Optional)
+
+When ready, test on Raspberry Pi:
+
+```bash
+# Deploy to Pi
+rsync -avz plugins/my-plugin/ pi@raspberrypi:/path/to/LEDMatrix/plugins/my-plugin/
+
+# Or if using git
+ssh pi@raspberrypi "cd /path/to/LEDMatrix/plugins/my-plugin && git pull"
+
+# Restart service
+ssh pi@raspberrypi "sudo systemctl restart ledmatrix"
+```
+
+## Common Customizations
+
+### Adding API Integration
+
+1. Add API key to `config_schema.json`:
+```json
+{
+  "api_key": {
+    "type": "string",
+    "description": "API key for service"
+  }
+}
+```
+
+2. Implement API call in `_fetch_data()`:
+```python
+import requests
+
+def _fetch_data(self):
+    response = requests.get(
+        "https://api.example.com/data",
+        headers={"Authorization": f"Bearer {self.api_key}"}
+    )
+    return response.json()
+```
+
+3. Store API key in `config/config_secrets.json`:
+```json
+{
+  "my-plugin": {
+    "api_key": "your-secret-key"
+  }
+}
+```
+
+### Adding Image Rendering
+
+There is no `draw_image()` helper on `DisplayManager`. To render an
+image, paste it directly onto the underlying PIL `Image`
+(`display_manager.image`) and then call `update_display()`:
+
+```python
+def _render_content(self):
+    # Load and paste image onto the display canvas
+    image = Image.open("assets/logo.png").convert("RGB")
+    self.display_manager.image.paste(image, (0, 0))
+
+    # Draw text overlay
+    self.display_manager.draw_text(
+        "Text",
+        x=10, y=20,
+        color=(255, 255, 255)
+    )
+
+    self.display_manager.update_display()
+```
+
+For transparency, paste with a mask:
+
+```python
+icon = Image.open("assets/icon.png").convert("RGBA")
+self.display_manager.image.paste(icon, (5, 5), icon)
+```
+
+
+### Adding Live Priority
+
+1. Enable in config:
+```json
+{
+  "my-plugin": {
+    "live_priority": true
+  }
+}
+```
+
+2. Implement `has_live_content()`:
+```python
+def has_live_content(self) -> bool:
+    return self.data and self.data.get("is_live", False)
+```
+
+3. Override `get_live_modes()` if needed:
+```python
+def get_live_modes(self) -> list:
+    return ["my_plugin_live_mode"]
+```
+
+## Troubleshooting
+
+### Plugin Not Loading
+
+- Check `manifest.json` syntax (must be valid JSON)
+- Verify `entry_point` file exists
+- Ensure `class_name` matches class name in manager.py
+- Check for import errors in logs
+
+### Configuration Errors
+
+- Validate config against `config_schema.json`
+- Check required fields are present
+- Verify data types match schema
+
+### Display Issues
+
+- Check display dimensions: `display_manager.width`, `display_manager.height`
+- Verify coordinates are within bounds
+- Ensure `update_display()` is called
+- Test with emulator first
+
+## Next Steps
+
+- Review existing plugins for patterns:
+  - `plugins/hockey-scoreboard/` - Sports scoreboard example
+  - `plugins/ledmatrix-music/` - Real-time data example
+  - `plugins/ledmatrix-stocks/` - Data display example
+
+- Read full documentation:
+  - `.cursor/plugins_guide.md` - Comprehensive guide
+  - `docs/PLUGIN_ARCHITECTURE_SPEC.md` - Architecture details
+  - `.cursorrules` - Development rules
+
+- Check plugin system code:
+  - `src/plugin_system/base_plugin.py` - Base class
+  - `src/plugin_system/plugin_manager.py` - Plugin manager

+
+## Plugin System Overview
+
+The LEDMatrix project uses a plugin-based architecture where all display functionality (except core calendar) is implemented as plugins. Plugins are dynamically loaded from the `plugins/` directory and integrated into the display rotation.
+
+### Plugin Architecture
+
+```
+LEDMatrix Core
+├── Plugin Manager (discovers, loads, manages plugins)
+├── Display Manager (handles LED matrix rendering)
+├── Cache Manager (data persistence)
+├── Config Manager (configuration management)
+└── Plugins/ (plugin directory)
+    ├── plugin-1/
+    ├── plugin-2/
+    └── ...
+```
+
+### Plugin Lifecycle
+
+1. **Discovery**: PluginManager scans `plugins/` for directories with `manifest.json`
+2. **Loading**: Plugin module is imported and class is instantiated
+3. **Configuration**: Plugin config is loaded from `config/config.json`
+4. **Validation**: `validate_config()` is called to verify configuration
+5. **Registration**: Plugin is added to available display modes
+6. **Execution**: `update()` is called periodically, `display()` is called during rotation
+
+---
+
+## Creating a New Plugin
+
+### Method 1: Using dev_plugin_setup.sh (Recommended)
+
+This method is best for plugins stored in separate Git repositories.
+
+#### From GitHub Repository
+
+```bash
+# Link a plugin from GitHub (auto-detects URL)
+./scripts/dev/dev_plugin_setup.sh link-github <plugin-name>
+
+# Example: Link hockey-scoreboard plugin
+./scripts/dev/dev_plugin_setup.sh link-github hockey-scoreboard
+
+# With custom URL
+./scripts/dev/dev_plugin_setup.sh link-github <plugin-name> https://github.com/user/repo.git
+```
+
+The script will:
+- Clone the repository to `~/.ledmatrix-dev-plugins/` (or configured directory)
+- Create a symlink in `plugins/<plugin-name>/` pointing to the cloned repo
+- Validate the plugin structure
+
+#### From Local Repository
+
+```bash
+# Link a local plugin repository
+./scripts/dev/dev_plugin_setup.sh link <plugin-name> <path-to-repo>
+
+# Example: Link a local plugin
+./scripts/dev/dev_plugin_setup.sh link my-plugin ../ledmatrix-my-plugin
+```
+
+### Method 2: Manual Plugin Creation
+
+1. **Create Plugin Directory**
+
+```bash
+mkdir -p plugins/my-plugin
+cd plugins/my-plugin
+```
+
+2. **Create manifest.json**
+
+```json
+{
+  "id": "my-plugin",
+  "name": "My Plugin",
+  "version": "1.0.0",
+  "author": "Your Name",
+  "description": "Description of what this plugin does",
+  "entry_point": "manager.py",
+  "class_name": "MyPlugin",
+  "category": "custom",
+  "tags": ["custom", "example"],
+  "display_modes": ["my_plugin"],
+  "update_interval": 60,
+  "default_duration": 15,
+  "requires": {
+    "python": ">=3.9"
+  },
+  "config_schema": "config_schema.json"
+}
+```
+
+3. **Create manager.py**
+
+```python
+from src.plugin_system.base_plugin import BasePlugin
+from PIL import Image
+import logging
+
+class MyPlugin(BasePlugin):
+    """My custom plugin implementation."""
+    
+    def update(self):
+        """Fetch/update data for this plugin."""
+        # Fetch data from API, files, etc.
+        # Use self.cache_manager for caching
+        cache_key = f"{self.plugin_id}_data"
+        cached = self.cache_manager.get(cache_key, max_age=3600)
+        if cached:
+            self.data = cached
+            return
+        
+        # Fetch new data
+        self.data = self._fetch_data()
+        self.cache_manager.set(cache_key, self.data)
+    
+    def display(self, force_clear=False):
+        """Render this plugin's display."""
+        if force_clear:
+            self.display_manager.clear()
+        
+        # Render content using display_manager
+        self.display_manager.draw_text(
+            "Hello, World!",
+            x=10, y=15,
+            color=(255, 255, 255)
+        )
+        
+        self.display_manager.update_display()
+    
+    def _fetch_data(self):
+        """Fetch data from external source."""
+        # Implement your data fetching logic
+        return {"message": "Hello, World!"}
+    
+    def validate_config(self):
+        """Validate plugin configuration."""
+        # Check required config fields
+        if not super().validate_config():
+            return False
+        
+        # Add custom validation
+        required_fields = ['api_key']  # Example
+        for field in required_fields:
+            if field not in self.config:
+                self.logger.error(f"Missing required field: {field}")
+                return False
+        
+        return True
+```
+
+4. **Create config_schema.json**
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "enabled": {
+      "type": "boolean",
+      "default": true,
+      "description": "Enable or disable this plugin"
+    },
+    "display_duration": {
+      "type": "number",
+      "default": 15,
+      "minimum": 1,
+      "description": "How long to display this plugin (seconds)"
+    },
+    "api_key": {
+      "type": "string",
+      "description": "API key for external service"
+    }
+  },
+  "required": ["enabled"]
+}
+```
+
+5. **Create requirements.txt** (if needed)
+
+```
+requests>=2.28.0
+pillow>=9.0.0
+```
+
+6. **Create README.md**
+
+Document your plugin's functionality, configuration options, and usage.
+
+---
+
+## Running Plugins
+
+### Development Mode (Emulator)
+
+Run the LEDMatrix system with emulator for plugin testing:
+
+```bash
+# Using run.py
+python run.py --emulator
+
+# Using emulator script
+./run_emulator.sh
+```
+
+The emulator will:
+- Load all enabled plugins
+- Display plugin content in a window (simulating LED matrix)
+- Show logs for plugin loading and execution
+- Allow testing without Raspberry Pi hardware
+
+### Production Mode (Raspberry Pi)
+
+Run on actual Raspberry Pi hardware:
+
+```bash
+# Direct execution
+python run.py
+
+# As systemd service
+sudo systemctl start ledmatrix
+sudo systemctl status ledmatrix
+sudo journalctl -u ledmatrix -f  # View logs
+```
+
+### Plugin-Specific Testing
+
+Test individual plugin loading:
+
+```python
+# test_my_plugin.py
+from src.plugin_system.plugin_manager import PluginManager
+from src.config_manager import ConfigManager
+from src.display_manager import DisplayManager
+from src.cache_manager import CacheManager
+
+# Initialize managers
+config_manager = ConfigManager()
+config = config_manager.load_config()
+display_manager = DisplayManager(config)
+cache_manager = CacheManager()
+
+# Initialize plugin manager
+plugin_manager = PluginManager(
+    plugins_dir="plugins",
+    config_manager=config_manager,
+    display_manager=display_manager,
+    cache_manager=cache_manager
+)
+
+# Discover and load plugin
+plugins = plugin_manager.discover_plugins()
+print(f"Discovered plugins: {plugins}")
+
+if "my-plugin" in plugins:
+    if plugin_manager.load_plugin("my-plugin"):
+        plugin = plugin_manager.get_plugin("my-plugin")
+        plugin.update()
+        plugin.display()
+        print("Plugin loaded and displayed successfully!")
+    else:
+        print("Failed to load plugin")
+```
+
+---
+
+## Loading Plugins
+
+### Enabling Plugins
+
+Plugins are enabled/disabled in `config/config.json`:
+
+```json
+{
+  "my-plugin": {
+    "enabled": true,
+    "display_duration": 15,
+    "api_key": "your-api-key-here"
+  }
+}
+```
+
+### Plugin Configuration Structure
+
+Each plugin has its own section in `config/config.json`:
+
+```json
+{
+  "<plugin-id>": {
+    "enabled": true,                    // Enable/disable plugin
+    "display_duration": 15,             // Display duration in seconds
+    "live_priority": false,             // Enable live priority takeover
+    "high_performance_transitions": false, // Use 120 FPS transitions
+    "transition": {                     // Transition configuration
+      "type": "redraw",                 // Transition type
+      "speed": 2,                       // Transition speed
+      "enabled": true                   // Enable transitions
+    },
+    // ... plugin-specific configuration
+  }
+}
+```
+
+### Secrets Management
+
+Store sensitive data (API keys, tokens) in `config/config_secrets.json`
+under the same plugin id you use in `config/config.json`:
+
+```json
+{
+  "my-plugin": {
+    "api_key": "secret-api-key-here"
+  }
+}
+```
+
+At load time, the config manager deep-merges `config_secrets.json` into
+the main config (verified at `src/config_manager.py:162-172`). So in
+your plugin's code:
+
+```python
+class MyPlugin(BasePlugin):
+    def __init__(self, plugin_id, config, display_manager, cache_manager, plugin_manager):
+        super().__init__(plugin_id, config, display_manager, cache_manager, plugin_manager)
+        self.api_key = config.get("api_key")  # already merged from secrets
+```
+
+There is no separate `config_secrets` reference field — just put the
+secret value under the same plugin namespace and read it from the
+merged config.
+
+### Plugin Discovery
+
+Plugins are automatically discovered when:
+- Directory exists in `plugins/`
+- Directory contains `manifest.json`
+- Manifest has required fields (`id`, `entry_point`, `class_name`)
+
+Check discovered plugins:
+
+```bash
+# Using dev_plugin_setup.sh
+./scripts/dev/dev_plugin_setup.sh list
+
+# Output shows:
+# ✓ plugin-name (symlink)
+#   → /path/to/repo
+#   ✓ Git repo is clean (branch: main)
+```
+
+### Plugin Status
+
+Check plugin status and git information:
+
+```bash
+./scripts/dev/dev_plugin_setup.sh status
+
+# Output shows:
+# ✓ plugin-name
+#   Path: /path/to/repo
+#   Branch: main
+#   Remote: https://github.com/user/repo.git
+#   Status: Clean and up to date
+```
+
+---
+
+## Plugin Development Workflow
+
+### 1. Initial Setup
+
+```bash
+# Create or clone plugin repository
+git clone https://github.com/user/ledmatrix-my-plugin.git
+cd ledmatrix-my-plugin
+
+# Link to LEDMatrix project
+cd /path/to/LEDMatrix
+./scripts/dev/dev_plugin_setup.sh link my-plugin ../ledmatrix-my-plugin
+```
+
+### 2. Development Cycle
+
+1. **Edit plugin code** in linked repository
+2. **Test with the dev preview server**:
+   `python3 scripts/dev_server.py` (then open `http://localhost:5001`).
+   Or run the full display in emulator mode with
+   `python3 run.py --emulator` (or equivalently
+   `EMULATOR=true python3 run.py`). The `-e`/`--emulator` CLI flag is
+   defined in `run.py:19-20` and sets the same `EMULATOR` environment
+   variable internally.
+3. **Check logs** for errors or warnings
+4. **Update configuration** in `config/config.json` if needed
+5. **Iterate** until plugin works correctly
+
+### 3. Testing on Hardware
+
+```bash
+# Deploy to Raspberry Pi
+rsync -avz plugins/my-plugin/ ledpi@your-pi-ip:/path/to/LEDMatrix/plugins/my-plugin/
+
+# Or if using git, pull on Pi
+ssh ledpi@your-pi-ip "cd /path/to/LEDMatrix/plugins/my-plugin && git pull"
+
+# Restart service
+ssh ledpi@your-pi-ip "sudo systemctl restart ledmatrix"
+```
+
+### 4. Updating Plugins
+
+```bash
+# Update single plugin from git
+./scripts/dev/dev_plugin_setup.sh update my-plugin
+
+# Update all linked plugins
+./scripts/dev/dev_plugin_setup.sh update
+```
+
+### 5. Unlinking Plugins
+
+```bash
+# Remove symlink (preserves repository)
+./scripts/dev/dev_plugin_setup.sh unlink my-plugin
+```
+
+---
+
+## Testing Plugins
+
+### Unit Testing
+
+Create test files in plugin directory:
+
+```python
+# plugins/my-plugin/test_my_plugin.py
+import unittest
+from unittest.mock import Mock, MagicMock
+from manager import MyPlugin
+
+class TestMyPlugin(unittest.TestCase):
+    def setUp(self):
+        self.config = {"enabled": True}
+        self.display_manager = Mock()
+        self.cache_manager = Mock()
+        self.plugin_manager = Mock()
+        
+        self.plugin = MyPlugin(
+            plugin_id="my-plugin",
+            config=self.config,
+            display_manager=self.display_manager,
+            cache_manager=self.cache_manager,
+            plugin_manager=self.plugin_manager
+        )
+    
+    def test_plugin_initialization(self):
+        self.assertEqual(self.plugin.plugin_id, "my-plugin")
+        self.assertTrue(self.plugin.enabled)
+    
+    def test_config_validation(self):
+        self.assertTrue(self.plugin.validate_config())
+    
+    def test_update(self):
+        self.cache_manager.get.return_value = None
+        self.plugin.update()
+        # Assert data was fetched and cached
+    
+    def test_display(self):
+        self.plugin.display()
+        self.display_manager.draw_text.assert_called()
+        self.display_manager.update_display.assert_called()
+
+if __name__ == '__main__':
+    unittest.main()
+```
+
+Run tests:
+
+```bash
+cd plugins/my-plugin
+python -m pytest test_my_plugin.py
+# or
+python test_my_plugin.py
+```
+
+### Integration Testing
+
+Test plugin with actual managers:
+
+```python
+# test_plugin_integration.py
+from src.plugin_system.plugin_manager import PluginManager
+from src.config_manager import ConfigManager
+from src.display_manager import DisplayManager
+from src.cache_manager import CacheManager
+
+def test_plugin_loading():
+    config_manager = ConfigManager()
+    config = config_manager.load_config()
+    display_manager = DisplayManager(config)
+    cache_manager = CacheManager()
+    
+    plugin_manager = PluginManager(
+        plugins_dir="plugins",
+        config_manager=config_manager,
+        display_manager=display_manager,
+        cache_manager=cache_manager
+    )
+    
+    plugins = plugin_manager.discover_plugins()
+    assert "my-plugin" in plugins
+    
+    assert plugin_manager.load_plugin("my-plugin")
+    plugin = plugin_manager.get_plugin("my-plugin")
+    assert plugin is not None
+    assert plugin.enabled
+    
+    plugin.update()
+    plugin.display()
+```
+
+### Emulator Testing
+
+Test plugin rendering visually:
+
+```bash
+# Run with emulator
+python run.py --emulator
+
+# Plugin should appear in display rotation
+# Check logs for plugin loading and execution
+```
+
+### Hardware Testing
+
+1. Deploy plugin to Raspberry Pi
+2. Enable in `config/config.json`
+3. Restart LEDMatrix service
+4. Observe LED matrix display
+5. Check logs: `journalctl -u ledmatrix -f`
+
+---
+
+## Troubleshooting
+
+### Plugin Not Loading
+
+**Symptoms**: Plugin doesn't appear in available modes, no logs about plugin
+
+**Solutions**:
+1. Check plugin directory exists: `ls plugins/my-plugin/`
+2. Verify `manifest.json` exists and is valid JSON
+3. Check manifest has required fields: `id`, `entry_point`, `class_name`
+4. Verify entry_point file exists: `ls plugins/my-plugin/manager.py`
+5. Check class name matches: `grep "class.*Plugin" plugins/my-plugin/manager.py`
+6. Review logs for import errors
+
+### Plugin Loading but Not Displaying
+
+**Symptoms**: Plugin loads successfully but doesn't appear in rotation
+
+**Solutions**:
+1. Check plugin is enabled: `config/config.json` has `"enabled": true`
+2. Verify display_modes in manifest match config
+3. Check plugin is in rotation schedule
+4. Review `display()` method for errors
+5. Check logs for runtime errors
+
+### Configuration Errors
+
+**Symptoms**: Plugin fails to load, validation errors in logs
+
+**Solutions**:
+1. Validate config against `config_schema.json`
+2. Check required fields are present
+3. Verify data types match schema
+4. Check for typos in config keys
+5. Review `validate_config()` method
+
+### Import Errors
+
+**Symptoms**: ModuleNotFoundError or ImportError in logs
+
+**Solutions**:
+1. Install plugin dependencies: `pip install -r plugins/my-plugin/requirements.txt`
+2. Check Python path includes plugin directory
+3. Verify relative imports are correct
+4. Check for circular import issues
+5. Ensure all dependencies are in requirements.txt
+
+### Display Issues
+
+**Symptoms**: Plugin renders incorrectly or not at all
+
+**Solutions**:
+1. Check display dimensions: `display_manager.width`, `display_manager.height`
+2. Verify coordinates are within display bounds
+3. Check color values are valid (0-255)
+4. Ensure `update_display()` is called after rendering
+5. Test with emulator first to debug rendering
+
+### Performance Issues
+
+**Symptoms**: Slow display updates, high CPU usage
+
+**Solutions**:
+1. Use `cache_manager` to avoid excessive API calls
+2. Implement background data fetching
+3. Optimize rendering code
+4. Consider using `high_performance_transitions`
+5. Profile plugin code to identify bottlenecks
+
+### Git/Symlink Issues
+
+**Symptoms**: Plugin changes not appearing, broken symlinks
+
+**Solutions**:
+1. Check symlink: `ls -la plugins/my-plugin`
+2. Verify target exists: `readlink -f plugins/my-plugin`
+3. Update plugin: `./scripts/dev/dev_plugin_setup.sh update my-plugin`
+4. Re-link plugin if needed: `./scripts/dev/dev_plugin_setup.sh unlink my-plugin && ./scripts/dev/dev_plugin_setup.sh link my-plugin <path>`
+5. Check git status: `cd plugins/my-plugin && git status`
+

+
+# Python Coding Standards
+
+## Code Quality Principles
+- **Simplicity First**: Prefer clear, readable code over clever optimizations
+- **Explicit over Implicit**: Make intentions clear through naming and structure
+- **Fail Fast**: Validate inputs and handle errors early
+- **Documentation**: Use docstrings for classes and complex functions
+
+## Naming Conventions
+- **Classes**: PascalCase (e.g., `NHLRecentManager`)
+- **Functions/Variables**: snake_case (e.g., `fetch_game_data`)
+- **Constants**: UPPER_SNAKE_CASE (e.g., `ESPN_NHL_SCOREBOARD_URL`)
+- **Private methods**: Leading underscore (e.g., `_fetch_data`)
+
+## Error Handling
+- **Logging**: Use structured logging with context (e.g., `[NHL Recent]`)
+- **Exceptions**: Catch specific exceptions, not bare `except:`
+- **User-friendly messages**: Explain what went wrong and potential solutions
+- **Graceful degradation**: Continue operation when non-critical features fail
+
+## Manager Pattern
+All sports managers should follow this structure:
+```python
+class BaseManager:
+    def __init__(self, config, display_manager, cache_manager)
+    def update(self)  # Fetch and process data
+    def display(self, force_clear=False)  # Render to display
+```
+
+## Configuration Management
+- **Type hints**: Use for function parameters and return values
+- **Configuration validation**: Check required fields on initialization
+- **Default values**: Provide sensible defaults in code, not config
+- **Environment awareness**: Handle different deployment contexts

+
+# Configuration Management
+
+## Configuration Structure
+- **Main config**: [config/config.json](mdc:config/config.json) - Primary configuration
+- **Secrets**: [config/config_secrets.json](mdc:config/config_secrets.json) - API keys and sensitive data
+- **Templates**: [config/config.template.json](mdc:config/config.template.json) - Default values
+
+## Configuration Principles
+- **Validation**: Check required fields and data types on startup
+- **Defaults**: Provide sensible defaults in code, not just config
+- **Environment awareness**: Handle development vs production differences
+- **Security**: Never commit secrets to version control
+
+## Manager Configuration Pattern
+```python
+def __init__(self, config, display_manager, cache_manager):
+    self.mode_config = config.get("sport_scoreboard", {})
+    self.favorite_teams = self.mode_config.get("favorite_teams", [])
+    self.show_favorite_only = self.mode_config.get("show_favorite_teams_only", False)
+```
+
+## Required Configuration Sections
+- **Display settings**: Update intervals, display durations
+- **API settings**: Timeouts, retry logic, rate limiting
+- **Background service**: Threading, caching, priority settings
+- **Team preferences**: Favorite teams, filtering options
+
+## Configuration Validation
+- **Type checking**: Ensure numeric values are numbers, lists are lists
+- **Range validation**: Check that intervals are reasonable
+- **Dependency checking**: Verify required services are available
+- **Fallback values**: Provide defaults when config is missing or invalid
+
+## Best Practices
+- **Documentation**: Comment complex configuration options
+- **Examples**: Provide working examples in templates
+- **Migration**: Handle configuration changes between versions
+- **Testing**: Validate configuration in test environments

+
+# Error Handling and Logging
+
+## Logging Standards
+- **Structured prefixes**: Use consistent tags like `[NHL Recent]`, `[NFL Live]`
+- **Context information**: Include relevant details (team names, game status, dates)
+- **Appropriate levels**: 
+  - `info`: Normal operations and status updates
+  - `debug`: Detailed information for troubleshooting
+  - `warning`: Non-critical issues that should be noted
+  - `error`: Problems that need attention
+
+## Error Handling Patterns
+```python
+try:
+    data = self._fetch_data()
+    if not data or 'events' not in data:
+        self.logger.warning("[Manager] No events found in API response")
+        return
+except requests.exceptions.RequestException as e:
+    self.logger.error(f"[Manager] API error: {e}")
+    return None
+```
+
+## User-Friendly Messages
+- **Explain the situation**: "No games available during off-season"
+- **Provide context**: "NHL season typically runs October-June"
+- **Suggest solutions**: "Check back when season starts"
+- **Distinguish issues**: API problems vs no data vs filtering results
+
+## Graceful Degradation
+- **Fallback content**: Show alternative games when favorites unavailable
+- **Cached data**: Use cached data when API fails
+- **Service continuity**: Continue operation when non-critical features fail
+- **Clear communication**: Explain what's happening to users
+
+## Debugging Support
+- **Comprehensive logging**: Log API responses, filtering results, display updates
+- **State tracking**: Log current state and transitions
+- **Performance monitoring**: Track timing and resource usage
+- **Error context**: Include stack traces for debugging
+
+## Off-Season Awareness
+- **Seasonal messaging**: Different messages for different times of year
+- **Helpful context**: Explain why no games are available
+- **Future planning**: Mention when season starts
+- **Realistic expectations**: Set appropriate expectations during off-season

+
+## Emergency Procedures
+
+### Hotfix Process
+1. Create `hotfix/` branch from `main`
+2. Make minimal fix
+3. Test thoroughly
+4. Create PR with expedited review
+5. Merge to `main` and tag release
+6. Cherry-pick to other branches if needed
+
+### Rollback Process
+1. Identify last known good commit
+2. Create revert PR if possible
+3. Use `git revert` for clean rollback
+4. Tag rollback release
+5. Document issue and resolution
+
+## Best Practices

+# Raspberry Pi Development Guidelines
+
+## Hardware Constraints
+- **Pi-only execution**: Code must run on Raspberry Pi, not Windows development machine
+- **LED matrix library**: Uses [rpi-rgb-led-matrix-master/](mdc:rpi-rgb-led-matrix-master/) for hardware control
+- **Memory limitations**: Optimize for Pi's limited RAM
+- **Performance**: Consider Pi's CPU capabilities in design
+
+## Development Workflow
+- **Local development**: Write and test code on Windows
+- **Pi deployment**: Deploy and test on actual Pi hardware
+- **SSH access**: Use SSH for Pi-based testing and debugging
+- **Service management**: Use systemd services for production deployment
+
+## Testing Strategy
+- **Unit tests**: Test logic without hardware dependencies
+- **Integration tests**: Test with mock display managers
+- **Hardware tests**: Validate on actual Pi with LED matrix
+- **Performance tests**: Monitor memory and CPU usage
+
+## Deployment Considerations
+- **Service files**: [ledmatrix.service](mdc:ledmatrix.service), [ledmatrix-web.service](mdc:ledmatrix-web.service)
+- **Installation scripts**: [first_time_install.sh](mdc:first_time_install.sh), [install_service.sh](mdc:install_service.sh)
+- **Dependencies**: [requirements.txt](mdc:requirements.txt) for Pi environment
+- **Permissions**: Handle file permissions for Pi user
+
+## Performance Optimization
+- **Caching**: Use [src/cache_manager.py](mdc:src/cache_manager.py) for data persistence
+- **Background services**: Non-blocking data fetching
+- **Memory management**: Clean up resources regularly
+- **Display optimization**: Minimize unnecessary redraws
+
+## Debugging on Pi
+- **Logging**: Comprehensive logging for remote debugging
+- **Error reporting**: Clear error messages for troubleshooting
+- **Status monitoring**: Health checks and status reporting
+- **Remote access**: Web interface for configuration and monitoring

+# Sports Manager Development
+
+## Manager Architecture
+All sports managers inherit from base classes and follow consistent patterns:
+- **Base classes**: [src/nhl_managers.py](mdc:src/nhl_managers.py), [src/nfl_managers.py](mdc:src/nfl_managers.py)
+- **Common functionality**: Data fetching, caching, display rendering
+- **Configuration-driven**: Behavior controlled via config sections
+
+## Required Methods
+```python
+def __init__(self, config, display_manager, cache_manager)
+def update(self)  # Fetch fresh data
+def display(self, force_clear=False)  # Render current data
+```
+
+## Data Flow Pattern
+1. **Fetch**: Get data from API (with caching)
+2. **Process**: Extract relevant game information
+3. **Filter**: Apply favorite team preferences
+4. **Display**: Render to LED matrix
+
+## Logging Standards
+- **Structured prefixes**: `[NHL Recent]`, `[NFL Live]`, etc.
+- **Context information**: Include team names, game status, dates
+- **Debug levels**: Use appropriate log levels (info, debug, warning, error)
+- **User-friendly messages**: Explain what's happening and why
+
+## Error Handling
+- **API failures**: Log and continue with cached data if available
+- **No data scenarios**: Distinguish between API issues vs no games available
+- **Off-season awareness**: Provide helpful context during non-active periods
+- **Fallback behavior**: Show alternative content when preferred content unavailable
+
+## Configuration Integration
+- **Required settings**: Validate on initialization
+- **Optional settings**: Provide sensible defaults
+- **Background service**: Use for non-blocking data fetching
+- **Caching strategy**: Implement intelligent cache management

+# Testing Standards
+
+## Test Organization
+- **Test directory**: [test/](mdc:test/) - All test files
+- **Unit tests**: Test individual components in isolation
+- **Integration tests**: Test component interactions
+- **Hardware tests**: Validate on Raspberry Pi with actual LED matrix
+
+## Testing Principles
+- **Test behavior, not implementation**: Focus on what the code does, not how
+- **Mock external dependencies**: Use mocks for APIs, display managers, cache
+- **Test edge cases**: Empty data, API failures, configuration errors
+- **Pi-specific testing**: Validate hardware integration
+
+## Test Structure
+```python
+def test_manager_initialization():
+    """Test that manager initializes with valid config"""
+    config = {"sport_scoreboard": {"enabled": True}}
+    manager = ManagerClass(config, mock_display, mock_cache)
+    assert manager.enabled == True
+
+def test_api_failure_handling():
+    """Test graceful handling of API failures"""
+    # Test that system continues when API fails
+    # Verify fallback to cached data
+    # Check appropriate error logging
+```
+
+## Mock Patterns
+- **Display Manager**: Mock for testing without hardware
+- **Cache Manager**: Mock for testing data persistence
+- **API responses**: Mock for consistent test data
+- **Configuration**: Use test-specific configs
+
+## Test Categories
+- **Unit tests**: Individual manager methods
+- **Integration tests**: Manager interactions with services
+- **Configuration tests**: Validate config loading and validation
+- **Error handling tests**: API failures, invalid data, edge cases
+
+## Testing Best Practices
+- **Descriptive names**: Test names should explain what they test
+- **Single responsibility**: Each test should verify one thing
+- **Independent tests**: Tests should not depend on each other
+- **Clean setup/teardown**: Reset state between tests
+- **Pi compatibility**: Ensure tests work in Pi environment

+# LEDMatrix Plugin Development Rules
+
+## Plugin System Overview
+
+The LEDMatrix project uses a plugin-based architecture. All display
+functionality (except core calendar) is implemented as plugins that are
+dynamically loaded from the directory configured by
+`plugin_system.plugins_directory` in `config.json` — the default is
+`plugin-repos/` (per `config/config.template.json:130`).
+
+> **Fallback note (scoped):** `PluginManager.discover_plugins()`
+> (`src/plugin_system/plugin_manager.py:154`) only scans the
+> configured directory — there is no fallback to `plugins/` in the
+> main discovery path. A fallback to `plugins/` does exist in two
+> narrower places:
+> - `store_manager.py:1700-1718` — store operations (install/update/
+>   uninstall) check `plugins/` if the plugin isn't found in the
+>   configured directory, so plugin-store flows work even when your
+>   dev symlinks live in `plugins/`.
+> - `schema_manager.py:70-80` — `get_schema_path()` probes both
+>   `plugins/` and `plugin-repos/` for `config_schema.json` so the
+>   web UI form generation finds the schema regardless of where the
+>   plugin lives.
+>
+> The dev workflow in `scripts/dev/dev_plugin_setup.sh` creates
+> symlinks under `plugins/`, which is why the store and schema
+> fallbacks exist. For day-to-day development, set
+> `plugin_system.plugins_directory` to `plugins` so the main
+> discovery path picks up your symlinks.
+
+## Plugin Structure
+
+### Required Files
+- **manifest.json**: Plugin metadata, entry point, class name, dependencies
+- **manager.py**: Main plugin class (must inherit from `BasePlugin`)
+- **config_schema.json**: JSON schema for plugin configuration validation
+- **requirements.txt**: Python dependencies (if any)
+- **README.md**: Plugin documentation
+
+### Plugin Class Requirements
+- Must inherit from `src.plugin_system.base_plugin.BasePlugin`
+- Must implement `update()` method for data fetching
+- Must implement `display()` method for rendering
+- Should implement `validate_config()` for configuration validation
+- Optional: Override `has_live_content()` for live priority features
+
+## Plugin Development Workflow
+
+### 1. Creating a New Plugin
+
+**Option A: Use dev_plugin_setup.sh (Recommended)**
+```bash
+# Link from GitHub
+./scripts/dev/dev_plugin_setup.sh link-github <plugin-name>
+
+# Link local repository
+./scripts/dev/dev_plugin_setup.sh link <plugin-name> <path-to-repo>
+```
+
+**Option B: Manual Setup**
+1. Create directory in `plugin-repos/<plugin-id>/` (or `plugins/<plugin-id>/`
+   if you're using the dev fallback location)
+2. Add `manifest.json` with required fields
+3. Create `manager.py` with plugin class
+4. Add `config_schema.json` for configuration
+5. Enable plugin in `config/config.json` under `"<plugin-id>": {"enabled": true}`
+
+### 2. Plugin Configuration
+
+Plugins are configured in `config/config.json`:
+```json
+{
+  "<plugin-id>": {
+    "enabled": true,
+    "display_duration": 15,
+    "live_priority": false,
+    "high_performance_transitions": false,
+    "transition": {
+      "type": "redraw",
+      "speed": 2,
+      "enabled": true
+    },
+    // ... plugin-specific config
+  }
+}
+```
+
+### 3. Testing Plugins
+
+**On Development Machine:**
+- Run the dev preview server: `python3 scripts/dev_server.py` (then
+  open `http://localhost:5001`) — renders plugins in the browser
+  without running the full display loop
+- Or run the full display in emulator mode:
+  `python3 run.py --emulator` (or equivalently
+  `EMULATOR=true python3 run.py`, or `./scripts/dev/run_emulator.sh`).
+  The `-e`/`--emulator` CLI flag is defined in `run.py:19-20`.
+- Test plugin loading: Check logs for plugin discovery and loading
+- Validate configuration: Ensure config matches `config_schema.json`
+
+**On Raspberry Pi:**
+- Deploy and test on actual hardware
+- Monitor logs: `journalctl -u ledmatrix -f` (if running as service)
+- Check plugin status in web interface
+
+### 4. Plugin Development Best Practices
+
+**Code Organization:**
+- Keep plugin code in `plugin-repos/<plugin-id>/` (or its dev-time
+  symlink in `plugins/<plugin-id>/`)
+- Use shared assets from `assets/` directory when possible
+- Follow existing plugin patterns — canonical sources live in the
+  [`ledmatrix-plugins`](https://github.com/ChuckBuilds/ledmatrix-plugins)
+  repo (`plugins/hockey-scoreboard/`, `plugins/football-scoreboard/`,
+  `plugins/clock-simple/`, etc.)
+- Place shared utilities in `src/common/` if reusable across plugins
+
+**Configuration Management:**
+- Use `config_schema.json` for validation
+- Store secrets in `config/config_secrets.json` under the same plugin
+  id namespace as the main config — they're deep-merged into the main
+  config at load time (`src/config_manager.py:162-172`), so plugin
+  code reads them directly from `config.get(...)` like any other key
+- There is no separate `config_secrets` reference field
+- Validate all required fields in `validate_config()`
+
+**Error Handling:**
+- Use plugin's logger: `self.logger.info/error/warning()`
+- Handle API failures gracefully
+- Cache data to avoid excessive API calls
+- Provide fallback displays when data unavailable
+
+**Performance:**
+- Use `cache_manager` for API response caching
+- Implement background data fetching if needed
+- Use `high_performance_transitions` for smoother animations
+- Optimize rendering for Pi's limited resources
+
+**Display Rendering:**
+- Use `display_manager` for all drawing operations
+- Support different display sizes (check `display_manager.width/height`)
+- Use `apply_transition()` for smooth transitions between displays
+- Clear display before rendering: `display_manager.clear()`
+- Always call `display_manager.update_display()` after rendering
+
+## Plugin API Reference
+
+### BasePlugin Class
+Located in: `src/plugin_system/base_plugin.py`
+
+**Required Methods:**
+- `update()`: Fetch/update data (called based on `update_interval` in manifest)
+- `display(force_clear=False)`: Render plugin content
+
+**Optional Methods:**
+- `validate_config()`: Validate plugin configuration
+- `has_live_content()`: Return True if plugin has live/urgent content
+- `get_live_modes()`: Return list of modes for live priority
+- `cleanup()`: Clean up resources on unload
+- `on_config_change(new_config)`: Handle config updates
+- `on_enable()`: Called when plugin enabled
+- `on_disable()`: Called when plugin disabled
+
+**Available Properties:**
+- `self.plugin_id`: Plugin identifier
+- `self.config`: Plugin configuration dict
+- `self.display_manager`: Display manager instance
+- `self.cache_manager`: Cache manager instance
+- `self.plugin_manager`: Plugin manager reference
+- `self.logger`: Plugin-specific logger
+- `self.enabled`: Boolean enabled status
+- `self.transition_manager`: Transition system (if available)
+
+### Display Manager
+Located in: `src/display_manager.py`
+
+**Key Methods:**
+- `clear()`: Clear the display
+- `draw_text(text, x, y, color, font, small_font, centered)`: Draw text
+- `update_display()`: Push the buffer to the physical display
+- `draw_weather_icon(condition, x, y, size)`: Draw a weather icon
+- `width`, `height`: Display dimensions
+
+**Image rendering**: there is no `draw_image()` helper. Paste directly
+onto the underlying PIL Image:
+```python
+self.display_manager.image.paste(pil_image, (x, y))
+self.display_manager.update_display()
+```
+For transparency, paste with a mask: `image.paste(rgba, (x, y), rgba)`.
+
+### Cache Manager
+Located in: `src/cache_manager.py`
+
+**Key Methods:**
+- `get(key, max_age=300)`: Get cached value (returns None if missing/stale)
+- `set(key, value, ttl=None)`: Cache a value
+- `delete(key)` / `clear_cache(key=None)`: Remove a single cache entry,
+  or (for `clear_cache` with no argument) every cached entry. `delete`
+  is an alias for `clear_cache(key)`.
+- `get_cached_data_with_strategy(key, data_type)`: Cache get with
+  data-type-aware TTL strategy
+- `get_background_cached_data(key, sport_key)`: Cache get for the
+  background-fetch service path
+
+## Plugin Manifest Schema
+
+Required fields in `manifest.json`:
+- `id`: Unique plugin identifier (matches directory name)
+- `name`: Human-readable plugin name
+- `version`: Semantic version (e.g., "1.0.0")
+- `entry_point`: Python file (usually "manager.py")
+- `class_name`: Plugin class name (must match class in entry_point)
+- `display_modes`: Array of mode names this plugin provides
+
+Common optional fields:
+- `description`: Plugin description
+- `author`: Plugin author
+- `homepage`: Plugin homepage URL
+- `category`: Plugin category (e.g., "sports", "weather")
+- `tags`: Array of tags
+- `update_interval`: Seconds between update() calls (default: 60)
+- `default_duration`: Default display duration (default: 15)
+- `requires`: Python version, display size requirements
+- `config_schema`: Path to config schema file
+- `api_requirements`: API dependencies and rate limits
+
+## Plugin Loading Process
+
+1. **Discovery**: PluginManager scans `plugins/` directory for directories containing `manifest.json`
+2. **Validation**: Validates manifest structure and required fields
+3. **Loading**: Imports plugin module and instantiates plugin class
+4. **Configuration**: Loads plugin config from `config/config.json`
+5. **Validation**: Calls `validate_config()` on plugin instance
+6. **Registration**: Adds plugin to available modes and stores instance
+7. **Enablement**: Calls `on_enable()` if plugin is enabled
+
+## Common Plugin Patterns
+
+### Sports Scoreboard Plugin
+- Use `background_data_service.py` pattern for API fetching
+- Implement live/recent/upcoming game modes
+- Use `scoreboard_renderer.py` for consistent rendering
+- Support team filtering and game filtering
+- Use shared sports logos from `assets/sports/`
+
+### Data Display Plugin
+- Fetch data in `update()` method
+- Cache API responses using `cache_manager`
+- Render in `display()` method
+- Handle API errors gracefully
+- Provide configuration for refresh intervals
+
+### Real-time Content Plugin
+- Implement `has_live_content()` for live priority
+- Use `get_live_modes()` to specify which modes are live
+- Set `live_priority: true` in config to enable live takeover
+- Update data frequently when live content exists
+
+## Debugging Plugins
+
+**Check Plugin Loading:**
+- Review logs for plugin discovery messages
+- Verify manifest.json syntax is valid JSON
+- Check that class_name matches actual class name
+- Ensure entry_point file exists and is importable
+
+**Check Plugin Execution:**
+- Add logging statements in `update()` and `display()`
+- Use `self.logger` for plugin-specific logging
+- Check cache_manager for cached data
+- Verify display_manager is rendering correctly
+
+**Common Issues:**
+- Import errors: Check Python path and dependencies
+- Config errors: Validate against config_schema.json
+- Display issues: Check display dimensions and coordinate calculations
+- Performance: Monitor CPU/memory usage on Pi
+
+## Plugin Testing
+
+**Unit Tests:**
+- Test plugin class instantiation
+- Test `update()` data fetching logic
+- Test `display()` rendering logic
+- Test `validate_config()` with various configs
+- Mock `display_manager` and `cache_manager` for testing
+
+**Integration Tests:**
+- Test plugin loading via PluginManager
+- Test plugin with actual config
+- Test plugin with emulator display
+- Test plugin with cache_manager
+
+**Hardware Tests:**
+- Test on Raspberry Pi with LED matrix
+- Verify display rendering on actual hardware
+- Test performance under load
+- Test with other plugins enabled
+
+## File Organization
+
+```
+plugins/
+  <plugin-id>/
+    manifest.json          # Plugin metadata
+    manager.py             # Main plugin class
+    config_schema.json     # Config validation schema
+    requirements.txt       # Python dependencies
+    README.md             # Plugin documentation
+    # Plugin-specific files
+    data_manager.py
+    renderer.py
+    etc.
+```
+
+## Git Workflow for Plugins
+
+**Plugin Development:**
+- Plugins are typically separate repositories
+- Use `dev_plugin_setup.sh` to link plugins for development
+- Symlinks are used to connect plugin repos to `plugins/` directory
+- Plugin repos follow naming: `ledmatrix-<plugin-name>`
+
+**Branching:**
+- Develop plugins in feature branches
+- Follow project branching conventions
+- Test plugins before merging to main
+
+**Automatic Version Bumping:**
+- **Automatic Version Management**: Version bumping is handled automatically via the pre-push git hook - no manual version bumping is required for normal development workflows
+- **GitHub as Source of Truth**: Plugin store always fetches latest versions from GitHub (releases/tags/manifest/commit)
+- **Pre-Push Hook**: Automatically bumps patch version and creates git tags when pushing code changes
+  - The hook is self-contained (no external dependencies) and works on any dev machine
+  - Installation: Copy the hook from LEDMatrix repo to your plugin repo:
+    ```bash
+    # From your plugin repository directory
+    cp /path/to/LEDMatrix/scripts/git-hooks/pre-push-plugin-version .git/hooks/pre-push
+    chmod +x .git/hooks/pre-push
+    ```
+  - Or use the installer script from the main LEDMatrix repo (one-time setup)
+  - The hook automatically:
+    1. Bumps the patch version (x.y.Z) in manifest.json when code changes are detected
+    2. Creates a git tag (v{version}) for the new version
+    3. Stages manifest.json for commit
+  - Skip auto-tagging: Set `SKIP_TAG=1` environment variable before pushing
+- **Manual Version Bumping (Edge Cases Only)**: Manual version bumps are only needed in rare circumstances:
+  - CI/CD pipelines that bypass git hooks
+  - Forked repositories without the pre-push hook installed
+  - Major/minor version bumps (hook only handles patch versions)
+  - When skipping auto-tagging but still needing a version bump
+  - For manual bumps, use the standalone script: `scripts/bump_plugin_version.py`
+- **Registry**: The plugin registry (plugins.json) stores only metadata (name, description, repo URL) - no versions
+- **Version Priority**: Plugin store checks versions in this order: GitHub Releases → GitHub Tags → Manifest from branch → Git commit hash

+- **Automatic version bumping**: Use the pre-push git hook for automatic patch version bumps

+- **GitHub as source of truth**: Plugin store fetches versions from GitHub releases/tags/manifest

-  cp /path/to/LEDMatrix/scripts/git-hooks/pre-push-plugin-version .git/hooks/pre-push
-  chmod +x .git/hooks/pre-push

-  Set `SKIP_TAG=1` in the environment to skip auto-tagging for one push.
-- **Manual versioning**: only needed for major/minor bumps, CI pipelines that
-  bypass hooks, or forks without the hook — use
-  `scripts/bump_plugin_version.py`.

 ## Common Issues by Category
 
-### Installation & Build Issues
-
-#### Step 6 fails: "Failed building wheel for rgbmatrix"
-
-**Symptoms:**
-
-```
-note: This error originates from a subprocess, and is likely not a problem with pip.
-  ERROR: Failed building wheel for rgbmatrix
-Failed to build rgbmatrix
-✗ Failed to install rpi-rgb-led-matrix Python package
-```
-
-**Cause:**
-
-Almost always the kernel's out-of-memory killer, not missing build tools. The
-`rpi-rgb-led-matrix` library compiles roughly 45 C++ translation units, two of
-them Cython-generated — a single `cc1plus` on those can peak near 800MB. The
-build system defaults to running several of those at once, which exceeds RAM on
-512MB and 1GB boards. Because the OOM killer writes nothing to pip's output, the
-failure looks like a toolchain problem, and `sudo apt install -y
-python-dev-is-python3 cmake build-essential` will report everything is already
-up to date.
-
-**How to confirm:**
-
-```bash
-dmesg -T | grep -i "out of memory"     # look for "Killed process ... (cc1plus)"
-free -h                                 # total RAM and swap
-```
-
-**Fix:**
-
-Current versions of the installer handle this automatically: they cap build
-parallelism based on available RAM and add a temporary swapfile for the build,
-removing it when the build finishes. If you are on an older checkout, or the
-temporary swapfile could not be created, either force a serial compile:
-
-```bash
-sudo ./first_time_install.sh --build-jobs 1
-```
-
-or add permanent swap and re-run the installer, which resumes at Step 6:
-
-```bash
-sudo apt install -y dphys-swapfile
-sudo sed -i 's/^#\?CONF_SWAPSIZE=.*/CONF_SWAPSIZE=2048/' /etc/dphys-swapfile
-sudo sed -i 's/^#\?CONF_MAXSWAP=.*/CONF_MAXSWAP=2048/' /etc/dphys-swapfile
-sudo dphys-swapfile swapoff && sudo dphys-swapfile setup && sudo dphys-swapfile swapon
-sudo ./first_time_install.sh
-```
-
-`CONF_MAXSWAP` matters: it defaults to 2048 and silently clamps `CONF_SWAPSIZE`,
-so setting only `CONF_SWAPSIZE` to a larger value has no effect.
-
-**Related:**
-
-- The installer needs roughly 3GB free on the card to place the swapfile. If
-  disk is tight it will say so and skip the swapfile: `sudo apt clean` first.
-- `sudo bash scripts/check_system_compatibility.sh` reports RAM and disk.
-- `sudo bash scripts/diagnose_dependencies.sh` dumps build-dependency state.

-Labels are **display only** — the stored value is still the enum value, so
-adding them never changes a saved config. The map may be partial: any value
-without a label keeps the humanised fallback. Older cores that predate this
-support ignore `x-options` and render the fallback for every option, so a
-plugin can ship labels without requiring a core upgrade.
-
-Array-table columns (`x-widget: array-table`) accept the same
-`x-options.labels` on a column definition, but their fallback is the **raw
-value** rather than the humanised one, because those columns hold values such
-as ticker symbols where `aapl` → "Aapl" would be wrong.

-said `"1.0.0"`; the bump to `"3.1.0"` did not land until 2026-07-12. Devices

-# compiles on a 4-core Pi. On a 512MB-1GB Pi the OOM killer reaps cc1plus and
-# pip reports only "Failed building wheel for rgbmatrix".

-# The caller runs under `set -Eeuo pipefail` with an ERR trap, and these are

-"""One place that answers "can this plugin run on this core?".
-
-Two callers ask that question and they must not drift apart:
-
-- `PluginLoader._warn_if_incompatible` — at load time, **advisory**. A plugin
-  already on disk keeps loading regardless, because the guarded-import pattern
-  means most incompatibilities degrade rather than break.
-- `PluginStoreManager.install_plugin` — at install/update time, **blocking**.
-  This is the point where refusing costs the user nothing (they keep the
-  version they already had) and allowing can cost them a plugin that fails to
-  load with only a log line to explain it.
-
-## The trustworthiness problem
-
-The core's own `__version__` has not always been right. `v3.1.0` was tagged
-2026-05-31 while `src/__init__.py` still said `"1.0.0"`; the bump landed
-2026-07-12. Devices installed from that release report `1.0.0` — below the
-floor that essentially every published plugin declares.
-
-So a core reporting a version below `TRUSTWORTHY_FLOOR` is treated as
-**unknown, not old**: it neither warns nor blocks. Blocking on it would be far
-worse than the problem being solved — nearly every manifest in the ecosystem
-floors at `2.0.0`, so a strict gate would stop those users installing *any*
-plugin. They are unprotected until they update the core, which is also what
-fixes their version string. See `docs/SPORTS_UNIFICATION.md`, phase B4.
