// fell back to the storage registry). The consequence that matters is the OLD box: a controller.yaml
// written before the deletion that still carries `hdd_path` (empty or not) must keep loading, with
// every other field intact — a config that fails to parse is a controller that does not start.
// RED-PROOF (REPORT): switch loadAndParse to a strict decoder (yaml KnownFields) and this fails.
