MnaRegistryLoader::loadFile parses one manifest JSON, walks the ops array, deserialises each entry into a MnaOpSchema with its port and attribute lists, and calls MnaOpRegistry::registerOp; missing or malformed entries are skipped with a warning so a single broken op does not abort the load. loadDirectory loads mna-registry.json first, then every *.json file under mna-registry.d/ in alphabetical order so later files override earlier definitions, which is how plug-in packages extend or shadow built-in ops.

saveFile inverts the process: it walks every schema currently registered with MnaOpRegistry, emits the canonical manifest header (mna_registry_version, provider) and the ops array, and writes the file pretty-printed so the output remains diff-friendly under version control.
