## Module Overview

Detailed documentation for each module in the project:

### Metadata (`meta.ipynb`)

> Metadata introspection for the Silero VAD plugin used by cjm-ctl to
> generate the registration manifest.

#### Import

``` python
from cjm_media_plugin_silero_vad.meta import (
    get_plugin_metadata
)
```

#### Functions

``` python
def get_plugin_metadata() -> Dict[str, Any]:  # Plugin metadata for manifest generation
    """Return metadata required to register this plugin with the PluginManager."""
    # Fallback base path (current behavior for backward compatibility)
    base_path = os.path.dirname(os.path.dirname(sys.executable))
    
    # Use CJM config if available
    cjm_data_dir = os.environ.get("CJM_DATA_DIR")
    
    # Plugin data directory
    plugin_name = "cjm-media-plugin-silero-vad"
    if cjm_data_dir
    "Return metadata required to register this plugin with the PluginManager."
```

### Silero VAD Plugin (`plugin.ipynb`)

> Plugin implementation for Voice Activity Detection using Silero VAD
> with SQLite result caching.

#### Import

``` python
from cjm_media_plugin_silero_vad.plugin import (
    SileroVADConfig,
    SileroVADPlugin
)
```

#### Classes

``` python
