"""
FC Debug Logging Module.

Provides modular, configurable debug logging for Function Calling components.

Usage:
    from logging_utils.fc_debug import get_fc_logger, FCModule

    fc_logger = get_fc_logger()

    # Log to specific modules
    fc_logger.debug(FCModule.CACHE, "Cache hit", req_id="abc123")
    fc_logger.info(FCModule.UI, "Toggle enabled", req_id="abc123")

    # Use convenience methods
    fc_logger.log_cache_hit(req_id, digest, age_seconds)
    fc_logger.log_ui_action(req_id, "click", "toggle_button", elapsed_ms=45.2)

    # Check if module is enabled (for performance-sensitive logging)
    if fc_logger.is_enabled(FCModule.SCHEMA):
        fc_logger.debug(FCModule.SCHEMA, "Converting tools", payload=tools)

Environment Variables:
    FC_DEBUG_ENABLED=true           # Master switch
    FC_DEBUG_CACHE=true             # Enable cache module
    FC_DEBUG_UI=true                # Enable UI module
    FC_DEBUG_LEVEL_CACHE=DEBUG      # Set log level for cache
    FC_DEBUG_COMBINED_LOG=true      # Also write to fc_combined.log
