Document logging, debug modules and the file logger The two getLogger() examples were not broken, but they are the ones a new plugin copies.
Document the stable-registry reload: no callback, no detach A plugin-owned ECStorage now opens once and survives core storage reloads untouched; openOrReload remains for the plugin's own config changing. SVWorldDataManager's canonical example loses the reload callback for the same reason.

Document the block store and link it from the storage pages
