Root cause: ExceptionHandlingInitializer attempted to autowire EnvironmentType directly, but it was never registered in the DI container. This caused the debug mode resolution to fail silently. Changes: - Use TypedConfiguration instead of EnvironmentType for proper DI - Create ErrorHandlingConfig value object to centralize config - Access debug mode via AppConfig.isDebugEnabled() which respects both APP_DEBUG env var AND EnvironmentType.isDebugEnabled() - Register ErrorHandlingConfig as singleton in container - Remove diagnostic logging from ResponseErrorRenderer This ensures that staging/production environments (where EnvironmentType != DEV) will not display stack traces, code context, or file paths in error responses.
