The extension class is specified via {env_prefix}_{prefix}_EXTENSION environment variable in the format "module.path:ClassName". Configuration for the extension is collected from all environment variables matching {env_prefix}_{prefix}_* (excluding the EXTENSION variable itself). Args: prefix: The extension prefix (e.g., "OPERATION_VALIDATOR"). base_class: The base class that the extension must inherit from. env_prefix: The environment variable prefix (default: "HINDSIGHT_API"). context: Optional ExtensionContext to provide system APIs to the extension. Returns: An instance of the extension, or None if not configured. Raises: ExtensionLoadError: If the extension fails to load or validate. Example: HINDSIGHT_API_OPERATION_VALIDATOR_EXTENSION=mypackage.validators:MyValidator HINDSIGHT_API_OPERATION_VALIDATOR_MAX_REQUESTS=100 ext = load_extension("OPERATION_VALIDATOR", OperationValidatorExtension) # ext.config == {"max_requests": "100"} _ _EXTENSIONzNo extension configured for NzLoading extension from =:zInvalid extension path 'z+'.
