The autoloader splits CamelCase on lowercase→uppercase transitions, so PRAutoBlogger_OpenRouter_Image_Provider maps to class-open-router-image-provider.php. Files were named class-openrouter-* (missing hyphen), causing a PHP fatal error when the pipeline tried to instantiate the provider — which killed the process before any logging could fire.
